There are SB firecrackers in the middle of the night, and the poor road is in a poor mental state.

For Ao Yan, a bunch of things that he couldn't play anymore turned into a strange vehicle that he hadn't seen before, and after Wei Xiaobei's refining and combination, he was able to pull himself to run on that track.

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

Of course, after understanding the structure and usefulness of this thing, it can be easily refined with Ao Yan's refining methods.

The most important thing here is the concept!

If it weren't for Wei Xiaobei's realistic concept of steam engine, Ao Yan might be able to refine clouds, flying cars, or something, but this steam engine train is impossible to refine.

"Xiaohong, Xiaohong, come and chase me!"

Ao Yan drove the small train and waved to Xiaohong, who was chasing after him, but he was very happy.

When Wei Xiaobei saw this scene, he felt a little heartache for Ao Yan, this kid, I'm afraid he hasn't played so happily since he was a child, right?

But looking at the little train, Wei Xiaobei's heart couldn't help but move, since this steam engine can be copied in the gray world, then the internal combustion engine, and even the electric motor, etc., can't be copied?

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

If you want to say that this steam engine, the internal combustion engine may be easier to copy, and the electric motor should not be difficult.

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

Making cars?

Well, airplanes and ships are still a bit useful, but that series of supporting things is not so easy to come up with.

Not to mention that it is extremely troublesome, but the use is relatively chicken.

To put it simply, what's the use of even if it's a whole car?

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

Well, in the Gray Realm, individual strength has made the usefulness of these mechanical creations relatively weak.

And if you want to make a more powerful mechanical creation, it will take a long time.

Wei Xiaobei didn't have that time to consume.

Of course, if it were just a steam engine, it would be of some use.

Thinking of this, Wei Xiaobei temporarily said goodbye to Ao Yan, who was having a good time, and turned around and headed towards the Great Plains.

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

I didn't come in for a while, and I don't know how much the area of this great plain has widened, and everywhere I look, there are farmlands, villages, and small towns.

Compared to before, I am afraid that it is more than ten times larger.

When rushing towards the direction of Daying, Wei Xiaobei also encountered a lot of caravans on the way.

But it's a bit too bad.

A dirt road is a road formed by clearing weeds and other things directly on the plains.

Just after a rain, and as soon as people walked away, as soon as the vehicles of those caravans were pressed, the dirt road became potholed and full of mud, not to mention the vehicles of those caravans, even Wei Xiaobei, if he didn't lift his breath and stepped on the air at a height of several meters, he would have to be covered in muddy water.

As for the vehicles of some caravans being stuck in mud puddles and unable to move, Wei Xiaobei saw too much.

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

"Big brother."

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

Zhao Yun put down the paperwork in his hand and chatted with Wei Xiaobei.

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

You must know that although the shark fishing camp catches a lot of fish every day, due to the transportation conditions, only one-third of the daily output can be transported to the big camp, so that a large amount of fish is piled up.

In addition, the Great Plains are now much wider, and the transportation of materials between the various cities is also a troublesome matter.

No way, the road is rotten!

"Second brother, this matter will be handed over to you, and the people and materials you need can be transferred to the master book."

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

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

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

Now it's okay, and I have a mess of things on my shoulders.

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

After finding Zhuge Master's Book, Wei Xiaobei inquired about the recent situation of the Tiewei Mountain, and then asked him to mobilize a group of craftsmen for backup.

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

As far as the current situation is concerned, Zhao Yunjun and Tieweishan are not large-scale wars, and small-scale conflicts are continuous.

Zhao Yunjun did not plan to directly attack Tiewei Mountain, Zhao Yun had already explained this.

There are many dangers in the Tiewei Mountain, but it is not a good place to go.

And those ironstone monsters in the Iron Fence Mountain will come out from time to time, and then be killed by the soldiers on the defense line, so as to become raw materials in the hands of craftsmen.

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

After all, a locomotive made of sand and gravel is good-looking, but in terms of firmness, it is far from good.

Let's just say that Ao Yan's locomotive, I'm afraid it won't be long before it will be destroyed.

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

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

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

Wei Xiaobei refined a batch of sledgehammers in batches and filled them with weapons.

These sledgehammers don't have much technical content, but they are solid in weight, and their production materials are the Heavenly Mountain Stones dug up by Wei Xiaobei from Heavenly Mountain.

These Heavenly Mountain Stones were melted and purified by the Dragon Fire Ding, and then turned into big hammers.

As for the runes, Wei Xiaobei didn't integrate them, you know, this integration into the runes is also a physical work, which requires a lot of energy.

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

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

It didn't take long for several wolf-type ironstone monsters to come out of the clouds, and after seeing this group of ordinary people, they immediately made a sound of gold and stone impact, although it was not as high as a wolf howl, but the sound was not small.

It didn't take long for the movement in the clouds to become larger, and one after another iron and stone monsters emerged from the clouds.

At this time, those ordinary people were also under Wei Xiaobei's order, and rushed towards those ironstone monsters, and when they got closer, they jumped high and smashed the big hammer in their hands towards the ironstone monsters.

To say, most of the ironstone monsters that appeared at this time were wolves, leopards, and some chickens, ducks, geese, and so on.

However, these iron-stone monsters did not seem to be afraid of this emotion, and when they saw the ordinary people rushing over, they immediately met them, pounced on them, jumped over, and two wild boars rushed over from the ground.

Bang bang bang

In an instant, a series of dull crashing sounds were heard.

To be honest, compared to the weapons used by the army, such as swords, guns, swords, and halberds, the blunt weapon of the sledgehammer is undoubtedly much stronger to deal with ironstone monsters.

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

Of course, the two ironstone monsters like wolves and leopards are much more difficult to deal with, in addition to their biological level as high as two-star horror, their body shape is also much more flexible than other ironstone monsters.

If these ordinary people had not formed a phalanx and advanced and retreated together, I am afraid that there would have been many casualties in the blink of an eye.

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

But as time passed, the common people became more and more courageous.

After all, they occupy the advantage of the formation and give full play to the strength of the group, while on the other hand, the ironstone monsters are chaotic, and they are completely fighting their own, and even some wolf-type ironstone monsters are injured, in order to recover from their injuries, they actually hunt and kill those small ironstone monsters, which further weakens the strength of the ironstone monsters.

Therefore, it didn't take long for more than a thousand ordinary people to kill five or six hundred iron and stone monster corpses all over the place, and many iron and stone monsters couldn't support it at this time, so they turned around and fled.

When the battle was over, the ordinary people quickly returned with the corpses of the iron-stone monsters they had killed.

And when they returned to the defensive line, there was a violent fluctuation in the clouds and mist of the Iron Fence Mountain, and more iron and stone monsters were killed from the rain and mist.

These ironstone monsters are much more powerful than the previous wave of ironstone monsters, and there are many giant beasts such as lions and elephants.

However, they appeared a little late, and the common people had already withdrawn, and when these ironstone monsters rushed over, the catapults, bed crossbows and other heavy weapons on the defense line began to wield their might, throwing boulders and crossbow arrows into the ironstone monsters, splashing pieces of ironstone fragments.

There is no doubt that even if there are many four-star ordinary and even four-star elites in these iron-stone monsters, it is really a little difficult to shake the defense line that Zhao Yunjun is waiting for.

The heavy weapons that were fired alone smashed the ironstone monsters in the middle of the charge.

As soon as they got close to the line, countless traps appeared, and some of them were trapped.

And at this time, the generals sitting on the defense line also took action one after another and beat the water dogs.

As a result, the ironstone monsters approached the defense line for a moment, and then had to hurriedly turn around and flee for their lives.

Even so, before they could escape back to the clouds of Tiewei Mountain, the generals who were going to be hunted down would leave behind a lot of corpses.

I have to say that this harvest is very good, and the corpses of those ironstone monsters are all good steel materials.

Of course, Wei Xiaobei paid more attention to his ordinary people at this time.

There is no doubt that the effect of Combat Evolution is indeed useful.

Among this group of ordinary people, the luckiest one has been upgraded to a two-star horror level.

The ordinary people who were slightly unlucky were also promoted to the two-star elite, and of course, more ordinary people still have the strength of two-star ordinary people. (To be continued.) )
