There are firecrackers in the middle of the night.........I am in a bad state of mind.

-------------------------

For Ao Yan, a bunch of things that he could no longer play with were transformed and combined after Wei Xiaobei's refining and combining, it turned into a strange vehicle that he had never seen before, and could still pull himself to run on that track.

I have to say, this is a bit magical.

Of course, after understanding the structure and use of this thing, Ao Yan's weapon refining method can be easily refined.

The most important thing here is the concept!

If there was no realistic steam engine concept like Wei Xiaobei, Ao Yan might be able to refine clouds, speed cars, etc., but this steam engine and train would never be able to refine it.

"Xiaohong, Xiaohong, come and chase me!"

Ao Yan drove a small train and waved to Xiaohong who was chasing him behind, and he was extremely happy.

Wei Xiaobei felt a little sad about Ao Yan when he saw this scene. I'm afraid this child has never played so happily since he was a child, right?

However, looking at the small train, Wei Xiaobei couldn't help but feel his heart. Since the steam engine can be copied in the ash world, then can the internal combustion engine, even the electric motor, etc. be copied?

However, Wei Xiaobei just thought about it for the time being.

To talk about this steam engine, an internal combustion engine may be easier to replicate, and the motor should not be difficult.

But the question is, what is the use of these things?

Making a car?

Well, planes and ships are a bit useful, but that series of supporting things are not so easy to make.

Not to mention the troublesomeness, but the purpose is rather useless.

Simply put, what's the use of a car?

The speed of those dragon and horses running is not slower than ordinary cars, and it is even much faster!

Well, in the gray world, individual strength has made the use of these mechanical creations relatively weak.

It takes a long time to create a more powerful mechanical creation.

Wei Xiaobei doesn't have that time to spend it.

Of course, if it is just this steam train, it will be of some use.

Thinking of this, Wei Xiaobei said goodbye to Ao Yan, who was having fun for a while, and turned toward the direction of the Great Plain.

When Wei Xiaobei walked out of the desert and saw the Great Plain, he was a little surprised.

I haven't come in for a while, and I don't know how much the area of ​​this big plain has expanded. Wherever I look, there are farmland, villages, and small towns everywhere.

Compared to before, it may have expanded by more than ten times.

While rushing towards the direction of the camp, Wei Xiaobei encountered many caravans on the road.

But this road is a bit too bad.

A total of dirt roads are roads formed after cleaning weeds and other things on the plains.

As soon as it rained, when someone left, the caravans' vehicles pressed down, the dirt road became bumpy and covered with mud. Not to mention the caravans' vehicles, even Wei Xiaobei would have to be covered in mud if he didn't take the air and stepped on the air at a height of several meters.

As for some caravans' vehicles being trapped in mud pits and unable to move, Wei Xiaobei saw a lot.

After entering the camp, he found the tent of the central army, lifted the curtain and saw Zhao Yun sitting in front of the desk busy.

"Big Brother."

Wei Xiaobei greeted him, Zhao Yun raised his head and saw that it was Wei Xiaobei, and couldn't help but feel a little surprised: "Second brother is back?"

Zhao Yun put down the documents in his hand and started chatting with Wei Xiaobei.

After hearing Wei Xiaobei say that what train can improve transportation conditions, Zhao Yun couldn't help but feel happy.

You should know that although the shark catches a lot every day, due to transportation conditions, only one-third of the daily output can be transported to the camp, causing a large amount of fishing catches to accumulate.

In addition, the area of ​​the Great Plain has now expanded a lot, and material transportation between cities is also a troublesome.

No way, the road is broken!

"Second brother, I'll leave this matter to you. Please contact the chief clerk to transfer the personnel and materials you need."

Zhao Yun directly handed his waist card to Wei Xiaobei and entrusted the matter.

After taking the errand, Wei Xiaobei remembered what he was doing when he entered the gray world this time.

I came in by testing the combat evolution ability of nurturing creatures.

Now, I'm carrying all the things on my shoulders.

Of course, with Wei Xiaobei's current mind, it is not difficult to resolve this conflict.

After finding Zhuge Zhuge, Wei Xiaobei asked about the recent situation of Tieweishan, and then asked him to mobilize a group of craftsmen to set aside.

Afterwards, Wei Xiaobei went directly to the Tieweishan defense line.

As of the current situation, Zhao Yunjun and Tieweishan have no large-scale wars, and there are constant small-scale conflicts.

Zhao Yun's army did not intend to directly attack Tiewei Mountain, which Zhao Yun has explained.

The iron-environment mountain is full of dangers and is not a good place to go.

The iron and stone monsters in Tiewei Mountain will come out from time to time and be killed by soldiers on the defense line, thus becoming the raw materials for the craftsmen.

This time, Wei Xiaobei is planning to use those iron and stone monsters to try the combat evolution effect of cultivating creatures. At the same time, those killed iron and stone monsters will become materials for refining locomotives and railway tracks.

After all, the locomotive made of gravel is quite good-looking, but in terms of strength, it is far from the bottom.

Just talking about the locomotive Ao Yan, it will probably be destroyed in no time.

Therefore, it is better to make it with iron and stone.

In the following time, Wei Xiaobei cultivated thousands of ordinary people.

After the evolution of the Altar of Life, although the strength of ordinary people has not improved much, just looking at their eyes is much more flexible than before.

Wei Xiaobei refined a batch of sledgehammers in batches, filling them with their weapons.

These sledgehammers do not have much technical content, but their strength lies in their solid weight. The material is the Heavenly Mountain stone dug by Wei Xiaobei from Heavenly Mountain.

After being melted and purified by the Dragon Fire Cauldron, these heavenly rocks turned into big hammers.

As for runes, Wei Xiaobei has not integrated them. You should know that integrating runes is also a physical job and requires a lot of energy to consume.

Thousands of ordinary people, carrying big hammers, set out towards Tieweishan.

Perhaps I felt the approaching of a large group of creatures, and there was some movement in the clouds and mist on the Tiewei Mountain.

Not long after, several wolf-shaped iron and stone monsters emerged from the clouds and mist. After seeing these ordinary people, they immediately made a sound of metal and stone collision. Although they were not as high as the howl of the wolf, the sound was not small.

Not long after, the movements in the clouds became larger, and iron and stone monsters emerged from the clouds.

At this time, under the order of Wei Xiaobei, those ordinary people rushed towards the iron and stone monsters. When they got closer, they jumped high and smashed the big hammer in their hands towards the iron and stone monsters.

It should be said that most of the iron and stone monsters that appeared at this time were wolf, leopard, chicken, duck, geese, etc.

However, these iron and stone monsters seemed not afraid of this. When they saw the generals rushing over, they immediately fought, rushing over, jumping over, and two wild boars rushed over from the ground.

Bang bang bang...

In the meantime, a series of dull collisions came out.

To be honest, compared with the weapons commonly used by the army such as swords, guns, swords and halberds, blunt weapons such as the Big Hammer are undoubtedly much stronger than those used to deal with iron and stone monsters.

Like chickens, ducks, geese, birds and other small iron and stone monsters, in front of ordinary people, they were the goods smashed by two hammers.

Of course, the two iron and stone monsters like wolves and leopards are much harder to deal with. In addition to their biological level as high as two-star terrifying, their bodies are also much more flexible than other iron and stone monsters.

If these ordinary people did not form a square formation and advance and retreat together, there would probably be many casualties in the blink of an eye.

Of course, there were also many casualties on the ordinary side.

But as time goes by, the generals become more and more braver.

After all, they occupied the advantage of the formation and fully utilized the strength of the group. On the other hand, the iron stone monsters were in chaos and they were all attacking their own. Even some wolf-type iron stone monsters were injured, in order to recover from their injuries, they actually hunted and killed small iron stone monsters, which further weakened the strength of the iron stone monsters.

Therefore, not long after, a thousand people killed five or six hundred iron and stone monsters everywhere, and many iron and stone monsters could not hold on at this time, so they turned around and ran away.

When the battle ended, the ordinary people dragged the corpses of the iron and stone monsters they killed and returned quickly.

When they returned to the defense line, there was a violent fluctuation in the clouds and mist of the Tiewei Mountain, and more iron and stone monsters were killed out of the rain and fog.

These iron and stone monsters are much more powerful than the previous wave of iron and stone monsters, and there are many lions and giant beasts like this.

However, they appeared a little late, and the people had all withdrawn. When these iron and stone monsters rushed over, heavy weapons such as catapults, bed crossbows and other heavy weapons on the defense line began to show their power, throwing huge rocks and crossbow arrows into the iron and stone monster group, splashing pieces of iron and stone fragments.

There is no doubt that even though there are many powerful existences of four-star ordinary people, or even four-star elites among these iron and stone monsters, it is really not very powerful to strike the defense line that Zhao Yunjun is ready for battle.

The heavy weapons fired alone knocked the iron and stone monsters in the charge into pieces.

When they approach the defense line, countless traps appear and some of them fall out.

At this time, the generals who were on the defense line also took action and beat the dogs in the water.

In this way, the iron and stone monsters approached the defense line and then had to turn around and run away.

Even so, before they escaped back to the Tiewei Mountain, the generals who were going to be hunted left behind many corpses.

I have to say that the harvest this time was very good, and the corpses of those iron and stone monsters were all of the best steel materials.

Of course, Wei Xiaobei is more concerned about his ordinary people at this time.

There is no doubt that the effect of combat evolution is indeed useful.

Among these ordinary people, the one with the best luck is that their creature level has been upgraded to two-star horror.
