Being able to keep the hunter is a good thing to celebrate for Lia and the Black Stone Collar.

Linda is about to have a qualified teacher.

...

Nearly afternoon, Qin Song and Alice were still busy in the hut. After a day of hard work and countless modifications and adjustments, a simple steel drilling machine about one meter long and a small simple milling machine half a meter long was finally completed.

There are seven types of brackets, slide rails, fixtures, and hand-pulled drill bits. There are seven types of drill bits alone, with different diameters and sizes. Although there are no high-end components such as bearings, the overall design is reasonable and enough to drill standard steel pipes. At least in this era, the accuracy is unparalleled.

Of course, the development work is not smooth. The larger the diameter, the more difficult it is to make, and the reason is the driving problem.

The initial was a hand-pulled drill bit. After Alice's plasticization, it was able to make steel pipes with a diameter of about 2-3 cm. As the diameter increased, the efficiency of the hand-pulled drill began to drop sharply. Steel pipes with more than five centimeters and huge drill bits could slowly drill in with the combined force of Qin Song and Alice.

The key reason is that Alice's plasticization ability cannot make the strength of the steel pipe too low, otherwise the pipe body will deform under the impact of the drill bit. But it cannot be too high, and it cannot be drilled in. Moreover, as time goes by, the strength of the pipe body continues to recover, and sometimes even the entire drill bit will be stuck inside.

In the end, after many efforts, the only large-diameter finished steel pipe was a steel pipe with a diameter of about 5 cm and a length of nearly one meter, which was only barely completed after drilling through both ends.

Qin Song stroked the shiny metal tube, and the joy on his face was beyond words. The caliber and length, as long as the shells were designed reasonably, it would be a deadly weapon that transcends the era.

"Huh." Alice wiped the fine sweat beads on her face. In order to drill out the steel pipe, she tried a lot of effort and her shoulders were sore: "Qin, is this kind of pipe the weapon you mentioned?"

"It's still too small." In Qin Song's imagination, the super-large caliber is the true meaning of the cannon. 5 cm is equivalent to 50 mm caliber. Even a mortar is light: "But it's barely enough."

"Uh, is it even bigger?" Alice stuck out her tongue: "Maybe we can ask Linda to help, she's even bigger than the two of us combined."

"Alice, why do you ask for help from others?" Qin Song smiled and shook his head: "Knowledge is power."

Alice asked again, but Qin Song put down the steel pipe: "Are you tired? Let's go out for a break and drink some water."

"Oh." Alice's divine power had just been used up, and she was indeed very tired mentally, and nodded obediently.

Adding some water to the soup pot from the water tank, Qin Song lit the bonfire below, then moved a wooden stool, sat under the shade of the stone house, quietly not talking.

Alice sat quietly beside him, but she was still thinking in her mind that 'knowledge is power'. After a while, she couldn't help but be curious and asked in a low voice: "Qin, do you mean, can knowledge replace us?"

“Not a substitution, but a transcendence.”

"Beyond?" Alice had no doubts: "Is it more than humanity's power?"

"Including the power of Linda."

Alice became more and more curious: "What kind of knowledge is that."

Qin Song turned his head, the light in his eyes jumped, and he slowly said, "Wait."

"Uh...wait? OK."

Gradually, the water in the soup pot began to produce white steam, and Qin Song added some firewood to make the fire more prosperous. Not long after, the water boiled and the steam sang out.

"Alice, what did you see?" Qin Song looked at Tang Pot with a smile.

Alice was stunned for a moment, with a confused expression on her face, and said tentatively: "The burning heat of fire makes the water boil."

"That is knowledge, Alice." Qin Song nodded: "Knowledge - exists in nature, exists around you. Boiling water is knowledge."

"Uh..." Alice's brows frowned: "That, knowledge--it's just boiling water?"

"That's right!" Qin Song stood up, found a wooden board and walked over, covered the soup pot, then sat down again, and continued to remain silent.

Alice stared at the wooden board tightly, and white steam began to gush out from the gap at the edge, and the wooden board continued to tremble.

"Alice, what did you see?"

Qin Song asked again, Alice thought carefully and said slowly: "The water vapor makes the lid jump."

Qin Song's lips curled up in a curve: "Yes, as you can see, this means that even water vapor has its own power. It looks very weak, right? But what if the surroundings are sealed, what will happen after continuous accumulation of weak power?"

"The power of water vapor? Continuous accumulation." Alice thought, and there seemed to be some inspiration in her mind: "It will lift the lid!"

"This is the power of boiling water. If we had a soup pot that was large enough, even a stone slab would probably not be able to stop the power of water."

"Qin, what you mean." Alice frowned: "We can use the power of water vapor, right? But I don't understand, how can we use this power? Can this power of water vapor really surpass people, or even Linda?"

"Knowledge will reveal the answer." Qin Song stood up and lifted the wooden board on the soup pot. The long-accumulated steam squirted out: "Alice, nature is the real power. As the gods said, everything he created contained wonderful knowledge, and we will uncover the true face of knowledge under the guidance of his wisdom."

"Is the power of boiling water?" Alice's heart felt a deep expectation: "What kind of power will that be?"

Qin Song smiled and filled the enamel wine glass with hot water: "Stay, take a break."

Holding the hot wine glass in his hand, Alice touched the heat with her hands, turned her head and saw Qin Song's beautiful side face. He blew the heat gently, and it looked so calm, full of wisdom.

Alice fell in love with him a little, cooperated tacitly, listened to his wisdom, or just stayed by his side quietly.

Stay away from the castle, away from the hustle and bustle, away from those troubled and trivial matters, and wander with him in the ocean of knowledge.

Wonderful and comfortable.

The power problem is the basis of industry. Now it relies on Alice's divine power, but if it is mass-made, her divine power is far from enough.

It's time to create a real artifact - a steam engine.

After drinking the hot water, Alice's divine power was almost restored. Qin Song put down the wine glass and smiled and said, "Alice, are you ready to solve the mystery with your own hands?"

Alice's eyes flashed with excitement and she said sweetly: "Ready!"

"Since it is the knowledge of boiling water, the first thing we do is to make boiling water utensils - pots and stoves."

“Put and stove?”

“Only by combining the two can we improve efficiency.”

"clear!"

The difficulty of a steam engine lies in the cylinder and piston, which have high accuracy requirements. The boiler requirement is sealing, and the accuracy requirements can be ignored.

"Come on, let's make a big iron sheet first."

Alice's plasticization ability is simply a magical tool for industrial manufacturing. It combines various functions such as forging, cutting, welding, etc., including the joints, which can be perfectly smoothed and integrated.

Soon, a large bucket surrounded by large iron sheets was made of a water tank base plate near the bottom, and the upper part was sealed with a conical lid, and the lower furnace had a square outlet and a chimney as a combustion chamber.

In this way, a simple version of the boiler was successfully manufactured.

"Qin, I understand a little bit." Alice looked at the boiler that was almost as tall as hers: "We want to seal the water gas in it, right?"

"That's right, but it can't be closed all the time, otherwise there will be serious consequences." Qin Song patted the lid at the top of the boiler: "We need to set an outlet for the water gas so that it can do the work."

"Do work?" Alice couldn't understand the meaning of the word.

"It's just let the water gas work."

"Let the water gas work?"

This sounded even more incredible. Alice was a little dizzy when she heard it, completely beyond people's imagination.

"Yes, so we want to create a place for water vapor." The principle of steam engine is very simple. There are countless handmade videos on the Internet, including various 'foreign guys hand-made mini steam engines', 'wood board steam engines' and even 'cardboard steam engines'.
