Sb set off firecrackers in the middle of the night My mental state is too poor.

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

For AO Yan, a pile of things he can't play anymore, after refining and combining by Wei Xiaobei, he turned into a strange vehicle he hasn't seen before, and he can also pull himself to run on that track.

I have to say, it's a little magical.

Of course, after understanding the structure and use of this thing, it can be easily refined by AO Yan's refining means.

The most important thing is the concept!

Without Wei Xiaobei's concept of steam engine in reality, Ao Yan might be able to refine clouds and flying cars, but this steam engine train can't be refined.

"Xiao Hong, Xiao Hong, come after me!"

Ao Yan drove a small train and waved to Xiao Hong who was chasing after him. He was very happy.

When Wei Xiaobei saw this scene, he felt some heartache for AO Yan. I'm afraid the child hasn't had such a happy play since he was a child?

However, looking at the small train, Wei Xiaobei couldn't help but move. Since the steam engine can be copied in the gray world, can't the internal combustion engine, even the motor, be copied?

However, Wei Xiaobei just thought so for the time being.

The steam engine and internal combustion engine may be easy to copy, and the motor should not be difficult.

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

Making cars?

Well, planes and ships are still useful, but it's not easy to get a series of supporting things.

It's very troublesome, but it's used for chicken ribs.

In short, what's the use of the whole car?

Those dragon horses can't run slower than ordinary cars, or even much faster!

Well, in the grey world, individual strength has made the use of these mechanical creations weaker.

It takes a long time to make more powerful mechanical creations.

Wei Xiaobei doesn't have that time to consume.

Of course, this steam engine train alone would be of some use.

Thinking of this, Wei Xiaobei said goodbye to Ao Yan, who had a good time, and turned to the great plain.

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

I haven't come in for such a period of time. I don't know how much the area of the great plain has been widened. Everywhere I can see, there are farmland, villages and towns.

I'm afraid it's more than ten times larger than before.

When he rushed towards the camp, Wei Xiaobei met many caravans on the road.

But this road is a little too bad.

A uniform dirt road is a road formed by directly clearing weeds on the plain.

Just after a rain, when people walk away, the dirt road becomes pitted and muddy as soon as the vehicles of those caravans are pressed. Not to mention the vehicles of those caravans, even Wei Xiaobei has to be covered with muddy water if he doesn't lift his breath and step on the air at a height of several meters.

As for the vehicles of some caravans trapped in the mud, Wei Xiaobei saw more.

After entering the camp, he found the big tent of the Chinese army, lifted the curtain and went in. He saw Zhao Yun sitting in front of the case and busy.

"Big brother."

Wei Xiaobei said hello. Zhao Yun looked up and saw that it was Wei Xiaobei. He was surprised: "the second brother is back?"

Zhao Yun put down his papers and chatted with Wei Xiaobei.

Hearing Wei Xiaobei say that what train can improve the transportation conditions, Zhao Yun couldn't help but rejoice.

You know, although the shark fishing camp catches a lot every day, due to the transportation conditions, only one third of the daily output can be transported to the camp, resulting in a large accumulation of catches.

In addition, the area of the Great Plains has expanded a lot, and the material transportation between cities is also a trouble.

No way, the road is rotten!

"Second brother, I'll leave it to you. You can find the master book to allocate the manpower and materials you need."

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

After taking the job, Wei Xiaobei remembered what he had come to do this time.

I came in to test the combat evolution ability of breeding creatures.

Now I'm ready to carry a lot of things on my shoulders.

Of course, with Wei Xiaobei's current brain, it is not difficult to solve this contradiction and conflict.

After finding Zhuge master's book, Wei Xiaobei asked about the recent Tiewei mountain, and then asked him to mobilize a group of craftsmen for standby.

After that, Wei Xiaobei went directly to the tieweishan defense line.

As far as the current situation is concerned, Zhao Yunjun and tieweishan belong to large-scale war, and there are no small-scale conflicts.

Zhao Yunjun did not intend to directly attack Tiewei mountain. Zhao Yun has explained this.

The Tiewei mountain is very dangerous. It's not a good place to go.

The iron stone monsters in Tiewei mountain will come out from time to time, and then be killed by the soldiers on the defense line, so as to become the raw materials in the hands of craftsmen.

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

After all, the locomotive made of gravel is certainly more beautiful, but it is far from strong.

Say Ao Yan's locomotive. I'm afraid it will be destroyed soon.

Therefore, it is better to make it with iron 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, their eyes are much more flexible than before.

Wei Xiaobei refined a batch of sledgehammers in batches to fill their weapons.

These sledgehammers don't have much technical content, but the victory lies in their solid weight. Their production material is the heaven mountain stone dug by Wei Xiaobei from heaven mountain.

After melting and purifying in the Dragon Fire tripod, these paradise rocks are turned into big hammers.

As for runes, Wei Xiaobei didn't integrate. You know, integrating runes is also a physical work, which requires a lot of spirit.

Thousands of ordinary people, carrying big hammers, set off towards Tiewei mountain.

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

Before long, several wolf type iron and stone monsters came out of the clouds. After seeing these ordinary people, they immediately made the sound of gold and stone impact. Although it was not as high as wolf howling, the sound was not small.

Before long, the movement in the clouds became larger, and an iron stone monster emerged from the clouds.

At this time, under the command of Wei Xiaobei, those ordinary people rushed towards the iron and stone monsters. When they got close, they jumped up 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 at this time are wolves, leopards, chickens, ducks and geese.

However, these iron and stone monsters didn't seem to be afraid of this emotion. When they saw the common people rushing over, they immediately met, rushed over, jumped over, and two wild boars rushed over from the ground.

Bang Bang

In a moment, a series of dull bangs came out.

To tell the truth, compared with the weapons commonly used by the army, the blunt weapon such as the big hammer is undoubtedly much stronger against iron and stone monsters.

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

Of course, two kinds of iron and stone monsters like wolf and leopard are much more difficult to deal with. In addition to their biological level up to two-star terror, their body shape is much more flexible than other iron and stone monsters.

If these ordinary people didn't form a square array and advance and retreat together, I'm afraid there would be many casualties in the twinkling of an eye.

Of course, there were many casualties on the common people's side.

But with the passage of time, the common people are more and more brave.

After all, they took advantage of the formation and gave full play to the strength of the group. On the other hand, the iron and stone monsters were in chaos. They fought each other completely. Even some wolf iron and stone monsters killed those small iron and stone monsters in order to recover from their injuries, which further weakened the strength of the iron and stone monsters.

So before long, a thousand people killed five or six hundred iron stone monsters everywhere. Many iron stone monsters couldn't support it at this time, so they turned and ran away.

When the battle was over, those ordinary people dragged the bodies of the killed iron stone monsters back quickly.

When they returned to the defense line, there was a violent fluctuation in the clouds around the iron mountain, and more iron stone monsters were killed from the rain and fog.

These iron stone monsters are much more powerful than the previous wave of iron stone monsters. There are many lions and giants like this.

However, they appeared a little late, and the common people had all withdrawn. When these iron and stone monsters rushed over, the catapults, bed crossbows and other heavy weapons on the defense line began to become powerful, throwing boulders and crossbows into the iron and stone monsters, splashing pieces of iron and stone fragments.

Prepared to meet the challenge of Zhao Yunjun's hard line, even if these iron stones are not strong enough for four stars or even the elite of four stars, there is no awesome force.

Only the heavy weapons fired one after another beat the iron and stone monsters in the charge.

When they get close to the defense line, countless traps appear and part of them fall.

At this time, the generals in charge of the defense line also shot one after another and beat the water dog.

In this way, those iron and stone monsters approached the defense line, and then had to turn around and run for their lives.

Even so, before they escape back to the clouds of Tiewei mountain, many bodies will be left by the army that will be pursued and killed again.

I have to say that this harvest is very good. The bodies of those iron and stone monsters are made of good steel materials.

Of course, Wei Xiaobei pays more attention to 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 has been upgraded to two-star terror.

The ordinary people with slightly poor luck have also been promoted to the two-star elite. Of course, more ordinary people are still two-star ordinary strength. (to be continued.)
