Yun Duo rolled his eyes secretly.

What era is this? I still admire the use of materials on animals as weapons and armor. It is so out of date and dare to call it "civilization" - Bah!

Looking back to the past, in the early days of human civilization, in the wilderness era before the Stone Age, the weapons and armor in human hands could only be used locally, using the bones of wild beasts as weapons, and then there was a stone replacement. So the Stone Age came, followed by the arrival of the Bronze Age...

It is understandable to think about it. The civilization of immortal cultivation was born in the wilderness era, mainly focusing on training personal strength. This civilization that originated in the wilderness era may never be able to get rid of the wilderness worship. Therefore, they have always continued the habit of using animal skins and bones to this day.

Yun Duo has not forgotten that this civilization is more respectful to the sages, and rarely questions the achievements of his predecessors, but only a blind respect, which makes it easy for people to admire what was created in ancient and wilderness. At the same time, this civilization also has its own brilliant features. For example, the training and exploration of personal abilities they created has reached the peak, which makes them ignore technological progress... Of course, with the ability of immortals, technology is no longer needed.

Think back to it, remember that several immortal masters in the town once said that the history of the powerful people chanted in the world of immortal cultivation can be traced back to more than 100,000 years ago, which means that the civilization of immortal cultivation has a longer period of writing, and this also means that the planet in front of us is far older than the planet where the clouds are located.

During the operation of the planet, it will constantly absorb dust in space and capture foreign stars such as meteors, making the planet's own body larger. As the planet becomes larger in size, the gravity becomes larger at the same time, so some macromolecular objects appear...

As the planet grows bigger, humans and animals have evolved their own evolution in order to adapt to the environment. Now it seems that they have evolved everything, but the tools used by the immortal civilization have not evolved. Perhaps this is the current situation where the animal skins and bones tools left over from ancient times are still in the coexistence of metal tools.

Look at what currency is used in the world of cultivation? It is actually a spirit stone. Isn’t this the residual stone worship in the Stone Age?

...

In the wilderness era, the first metal discovered by humans was tin, and then they discovered copper. These two metals were not as hard as stone tools, but they combined them to form bronze, which quickly replaced the stone civilization...

How lucky it was to be born in this civilization. With just a little effort... Yun Duo's eyes turned, and suddenly he raised his face and said to Bixi: "Nephew, turn around, stick out your butt, let me kick you, and then I will tell you a way to make you one of the best weapon refiners in this era."

Bixi sat upright lazily, looked at Yun Duo with contempt, and his butt didn't move, so he changed his posture and sat down again, saying indifferently: "Sir, I am a monk in the Foundation Establishment Stage, you are a commoner who has not yet drawn into your body. Even if I stick my butt up and let you kick it, the recoil force can shake you to death.

Uncle Master, do you know how much strength I used to endure it just now that I didn’t crush you to death?”

Yunduo stood up, moved his short legs, and crossed the threshold with difficulty. He walked to Bixi's desk with a stern face, knocked on the table with his index finger, raised his hand, and signaled Bixi to move aside: "Mr. Nephew, take a step away, let me sit down, and you will reply to me while standing."

Bixi tilted his head and looked at Yun Duo, but his face still didn't take it seriously. He asked carefully: "Are you really playing?"

For a long time, Yun Duo has always looked like a cute child who is pleasing to behave in front of Bixi. Suddenly becoming serious, Bixi is very uncomfortable... However, once Yun Duo becomes serious and takes the role of his uncle as his commander, Bixi can't be tough.

Yun Duo nodded heavily with a stern face. Bixi held on for a while, stood up lazily and moved away from the seat. He didn't dare to walk away, so he could only take a step back and stood up not far from the desk, lowered his head, waiting for Yun Duo's instructions.

This is the rule of the sect. If Bixi dares to resist a master of the Qing generation, all Jindan real people of the Qing generation, no matter what their relationship with Yun Duo is, they must unite to maintain the dignity of the Qing generation.

If this happens, Bixi will die without a place to bury him.

Yun Duo sat in front of the huge desk. The stool was relatively high, and his feet could hardly occupy the floor. He wanted to put his elbow on the desk and put his chin on his palm to make a contemplative look. However, the distance between the chair and the desk was too far, and the height of the desk was not suitable...

So he gestured for a long time, and could only cross his legs on the chair, put his elbow on his thighs, and put his adult thoughts: "Mr. Nephew, what is the sharpest weapon in the world?...It shouldn't be an iron weapon?"

Bixi honestly replied: "Uncle Shi is indeed not an iron tool, but an alloy composed of two rare metals. One of the metals is mitral, and the other heavy metal is called 'tianjin'. These two metals, the former is silver-white, a bit close to the color of silver; the other metal is slightly yellow and looks like gold, but it is heavier than gold at the same size."

clear!

These two things are similar to platinum and osmium alloys. The tools made of this alloy are much sharper than iron tools, but this alloy is still not the sharpest tool on earth. The sharpest weapon is actually an alloy composed of two radioactive metals...

Of course, if the planet becomes larger in size and the terrain gravity also increases, the original radioactive metal may lose its radioactivity due to the increased gravity, becoming a stable state - "heavy metal"!

"There should be a sharper weapon..."

Bixi raised his face with a memory expression and replied: "Have you heard of the 'ten weapons' legends on the mainland? The legendary weapon is called the Blazing Sword. It is said that once this sword is unsheathed, its light makes people dare not look directly at..."

Oh, it is a sword made of radioactive metal, so it emits dazzling light like the sun when it is unsheathed.

"...The second-ranked weapon is a long axe. This axe should be called an axe. Its light is also radiant and cannot be seen directly... Legend has it that this axe is left over from Xing Tian, ​​who created the world, so it is called Xing Tian Axe.

The third weapon is a bow. This bow is called a stringless bow. It has no bow string and does not require specific arrow branches. Once the person who pulls the bow has full of spiritual power, a light arrow will automatically appear on the bow string, and then the bow holder can hit it wherever he points..."

Yun Duo's eyes lit up. Maybe this bow is the most correct direction for the development of weapons!

The civilization of immortal cultivation originally paid special attention to collecting energy and accumulating energy, and the impact force and penetration of weapons, etc., to put it bluntly, it is just the damage caused by various energy.

Bixi sighed and continued, "...These three weapons were all taken by Taiyue. It is said that these three weapons were made by several weapon refiners tens of thousands of years ago..."

After pausing for a while, Bixi said again: "The sword in the hand of Master Duanjin is ranked 11th in the weapon spectrum. This sword is said to be made by the master of weapon refining 50,000 years ago. As soon as this sword is unsheathed, the wronged souls who were killed by this sword will cry and howl, causing the sharp sword of the golden blade to roar in the wind, which will capture people's hearts..."

Bixi continued to introduce the top ten famous weapons in the weapon list. Yun Duo interrupted the other party's narration and asked: "Mr. Nephew, I have heard that someone has added some metal to the animal skin armor to improve the quality of the animal skin armor and enhance the defense of the animal skin armor... Is there any such thing?"

Bixi is very good at it, so he picked up his fingers and introduced to Yunduo as many as possible that the metal and ore of animal leather armor could be mixed...

That's right. This shows that the predecessors once discovered the function of alloys and they also smelted various famous weapons. However, their smelting techniques were all based on empiricism, knowing the truth but not the reason. Therefore, the smelting principle was not passed down, so later generations could only tell their achievements on various occasions, but could not surpass these people.

Of course, this kind of speculation was made by Yun Duo with the greatest kindness. Maybe there is another reason why they did not say the smelting principle...

Various metals can be incorporated into the animal skin, which also means that during the evolution process, high-level monsters have consciously accumulated various heavy metals in their bodies to improve their defense, improve their skin firmness, and the sharpness of their attacks...

Based on this, the so-called absorption of spiritual energy into the body, forging Taoist foundations, Dharma bodies, etc. are actually interesting to create mutations in the human body to accumulate high-energy polymer substances in the human body.

"There is a way." Yun Duo no longer held his chin to make me think. He took out a lead strip from the storage bracelet, took a piece of talisman paper from the table, and drew a pattern on the talisman paper...

After finishing drawing this pattern, Yun Duo thought about it and drew another side view.

He handed the pattern to Bixi and Yunduo asked: "Mr. Nephew, can you make this kind of machine?"

Bixi's eyes fell on the top view, and he asked in confusion: "Six-hole lotus root?"

Yun Duo pointed at the picture below: "This picture is a side-study, just to observe from the side. The picture is not very similar to what I draw. The key to making this thing is that the six holes must be balanced, and the rotating spiral rod must be very solid..."

Bixi shook the child's talisman paper and asked: "Uncle Master, what is this?"

Yun Duo blurted out: "Centrifuge."

But Yun Duo immediately concealed and said, "No, this name is not easy to understand, so just call it a cyclone machine in a popular way?"

Bixi understood and immediately asked: "Don't you want to build this machine to make these six-hole lotus roots rotate like a whirlwind?"

Yun Duo went down the slope and said, "You can call Liukong and even the lotus root machine. This thing is the key to becoming a master of weapon refining. Let's make this thing first... However, you and I have to make an agreement in advance: after you start refining weapons, all the benefits will be half of you and half, okay?"

Bixi looked at Yunduo with his eyes slanted: "Uncle Master, this is not good. It's me who works hard to do it. You actually want to take away half of the profit?"

What Bixi hasn't said yet is: "You are an ordinary person. Can you do these things for you? Now if you talk and I do it, you will actually take away half of the profits. It's so unreasonable."

Yun Duo jumped off the chair, and he walked to Bixi, looked up at Bixi's shoulder, waved to him: "Squat down, squat down, my nephew, squat down and talk to me."

Bixi squatted down depressedly - even though he squatted down, his figure was still taller than Yunduo standing.

Yun Duo could only tiptoe and patted Bixi on the shoulder: "Bixi, my junior, a small gang, if you want to twist your strength into a rope and think about it in the same direction, you can only come from two situations, one is interests and the other is emotions.

Can you understand the so-called emotions? You and I are not blood relatives, so there is no family affection between us; you are a man, and I am a man, and we cannot have love; but you are not my enemy, and you and I have no common enemy, so we cannot have consistent hatred...

So after all, if you and I want to make big money together in the future and never leave me if I make enough money, it is unrealistic to maintain your cohesion by relying solely on feelings. So we can only talk about interests.

When it comes to interests, I am willing to share half of your profits. I am really too kind... Don't roll your eyes and tell you that only creativity in this world is the most valuable.

I have creativity, I have innovative ideas, and I have new ideas. Who will do the specific work? I can let you Bixi do this work, or I can grab someone from the road, ask him to finish the work, and then pay him a cent of the employee salary, only the employee salary--do you think so?"

The reason was clearly stated. Bixi thought about it for a while and thought to himself that this was really the case.

But can Bixi believe in clouds?

Such a guy who has not even completed the qi entering the body, such an absolute idiot who has the celestial spiritual roots and has not completed the qi entering the body for several months, can he come up with a great idea?"

Bixi's eyes fell on the design drawing and pondered, "Uncle Master, I don't know what this thing is for, but since you said: the rotating spiral rod in the middle must be very hard. It must be made of good materials - it may cost a lot to create such a thing."

Yun Duo continued to tiptoe, patted Bixi's shoulder like an adult, and said, "Mr. Nephew, since I have half of the profit, I will of course spend half of the investment. How much can this thing cost? 20,000 low-grade spirit stones? Then I will spend half of the funds, 10,000 low-grade spirit stones, what do you think?"

Bixi was startled: "Uncle Master, you are really rich, but I'm afraid I can't get it out of ten thousand low-grade spirit stones."

Yun Duo touched his chin and thought, "Then, we might as well invest less in advance, make a small one first, and try its effect?"

Bixi blurted out: "How young should you be? Uncle Master, can this thing be useful if it is small?"

Yun Duo nodded heavily: "It's useful, absolutely useful... You just mentioned the elixirs. How many elixirs are there in the city that are related to Yangshen Grass?"

Bixi immediately replied: "Among the foundation-building monks left this time, there is another monk named Biliu who has learned alchemy, but his alchemy is not very good... I'll call him over, can you talk to him?"

Biliu was called over quickly and saw Biliu squatting on the ground. The uncle of the junior teacher was walking around the room with his hands on his back. Biliu felt incredible... But it was not his business, he just needed to answer the questions.

"There are seven kinds of elixirs made of Yangshen Grass... Ah, the best sellers and the most expensive ones are the Yuanshen Pill, Qi Yi Pill, and the Tian Bu Tian Pill.

Among them, Yuanshen Pill is the most expensive, Qi-replenishing Pill is the cheapest, but the sales are the best. It is troublesome to make the Butian Pill, which requires more than 100 herbs, which are relatively rare on the market. The price is unspeakable...

What are the uses of these three elixirs? As the name suggests, the Yuanshen Pill is to make up for the injury of the Yuanshen; most Qi-replenishing Pills are taken by Qi-training practitioners. Cultivators in the Foundation Establishment Stage need to use the Tian-replenishing Pills, but if they cannot buy the Tian-replenishing Pills, it is barely enough to use Qi-replenishing Pills to replenish qi, but the amount taken at one time requires a lot...

How to refine Qi-enhancing pill? I can refine this. I have been doing this recently. There is no way. Now this sect mission is too leisurely. Cultivators in the Foundation Establishment Stage also have to live... What, the pill recipe, that is three portions of Yangshen Grass, one portion of Motherwort, and Baizhi..."

"Stop and stop", Yun Duo pondered at this question: "Three portions of Yangshen Grass, how do you measure this?"

Bi Liu looked puzzled: "A portion of Yangshen Grass is about two liang... The alchemy is measured in this way. This is the alchemy recipe that has been passed down from ancient times to the present. It is very effective. Why, uncle, are there any problems?"

Yun Duo waved his hand, and Bixi quickly interrupted: "Junior Brother Biliu, you go back."

When Biliu left the room, Yunduo patted Bixi's shoulder with an excited look on his face: "I've got rich, I've got rich... Well, can this Biliu trust me?"

Bixi thought for a while and replied: "Uncle Junior, the Foundation Establishment Stage disciples who stayed in Jieyin City this time are all those who are not very popular among the sects. Think about it, the war you see is coming, and the monsters in the monster jungle are ready to move. The sect hurriedly withdraws the main force. How could people with ability and background not follow the main force?"

Yun Duo shook his head and said contemptuously: "Mr. Nephew, you will definitely be stupid to death in the future... Oh, what should you do without me? Do you think that the excluded person is good-minded and will not betray him?"

Bixi thought for a while and said tentatively: "Uncle Master, you just said 'benefit' can increase cohesion, so why not let us pull him into the group...Uncle Master, I don't understand what you said just now. I was very nervous. If you pull one more person, you will spend a penny extra. If you fail, you can at least spread the risks."

Yun Duo shook his head: "Don't worry, let's make your little thing. This is the key to keeping it confidential and not let too many people know."

Bixi frowned and looked at Yunduo. After a long time, he made a decision: "Uncle Master, I am not rich... You just said that little thing can make money. Although I don't know how it makes money, if the uncle insists on making trouble, then I will take out two thousand low-grade spirit stones and play with the uncle. If there are more, I can't afford to play this game."

Yun Duo glared at Bixi with contempt: "One day, you will regret today's stinginess... Well, you will give two thousand low-grade spirit stones, and I will give two thousand too.

Now let me tell you about this rotating six-hole lotus root. The key to this thing is the spiral rod in the middle, which needs to rotate at high speed and is very high speed... Well, the rotation can be done using a cyclone talisman, and then powered by inlaid spirit stones.

Let's make a gadget first, but the rotating rod in the middle of this gadget should be strong enough. I plan to use the fourth-grade cyclone talisman to drive it. I don't know if the speed is enough. If it is not enough, it needs to be increased, at least to make it rotate at a speed of 10,000 revolutions in a blink of an eye.

The fourth-level whirlwind talisman is equivalent to the power of the peak stage of foundation building, so the rotating rod you make must at least be able to withstand the full-strength attack in the foundation building stage...

When this thing makes money, we will also make larger six-hole lotus roots. At that time, the speed needs to be higher and faster. The rotating rod in the middle will be at least able to withstand the power of the sixth and seventh grade whirlwind talisman..."
