The cold wind was blowing, but it couldn't blow away the hot scene on the leaf plain. There are already tens of thousands of nomads working here, and they can basically build a city.

The lockdown of Benlong City was lifted, and a large number of hunting teams went deep into the Burial Dragon Valley, and the souls in the Burial Dragon Valley were first killed by the black dragon who dragged the top of the "Heavenly Tribulation", and then killed a large number by the three-city alliance, plus the black dragon and the winged dragon were dead, the threat of the soul beasts of the entire Burial Dragon Valley was greatly reduced, and the hunting team naturally marched all the way and directly attacked the hinterland of the Burial Dragon Valley, and harvested a lot, especially the green vines as the basic food, in a month-long time, they grew wantonly, and this large number of green vines, It was also collected as a reward for the work of the nomads in the wilderness, and the hunting party received orders from Benlong City - not to care about the amount of green vine mined, how much to dig. Anyway, Ye Yu is already engaged in his "Soul Beast Farm", so he doesn't have to worry about the extinction of the green vine.

Against a cold wind, Ye Yu took Ah Fei and came to Ye Yuan's construction site to investigate, Liu Limeng probably never dreamed that with the support of the liaison station, Ye Yu's recovery speed was far beyond his imagination, although his body was still a little weak, Ye Yu could continue to jump around.

The skeleton of the city wall of the new city has been built, and there are forests of cement and steel bars everywhere, Ye Yu has almost exhausted all the steel stocks in the southern region in order to build the city wall, you know, there is no systematic steel mining in the last days, most of these steels are accumulated over time, and it is not easy to get these.

"Captain, can this work?" Ah Fei looked at this steel jungle with some uncertainty, "Aren't the city walls all made of stones?" Captain, can you handle a bunch of stone powder? Ah Fei said, picking up a ball of solidified cement and pinching it into a ball of powder with a gentle pinch. You see, the intensity is too low. ”

Ye Hao smiled, "You don't understand, reinforced concrete is a thing that turns decay into magic. Unless you can get enough chunks of granite or simply cast steel walls, reinforced concrete is the most cost-effective, convenient, and defensive model. ”

"Why?" Ah Fei had a curious baby's expression.

Ye Hao spread his hands, how did he know why! He didn't study engineering, but occasionally read some popular science about reinforced concrete on the Internet, in short, this thing is definitely stronger than building a wall with bricks, you know, a famous dam is all watered with high-strength concrete, which is claimed to be able to withstand the existence of nuclear bombs!

This is the advantage of modern society, even if you are not this major, but your vision is there, and your thinking is to be higher and farther than those who are backward in the world.

Ye Hui believes that with the scientific and technological level of Shushan, the knowledge of reinforced concrete is absolutely well understood, and many liaison stations are reinforced concrete structures, but they are not even willing to spread this most basic and convenient technology, which makes Ye Hui even more disgusted with Shushan.

In fact, the arrangement of the steel bars of this city wall may not be the most scientific, but it is already the limit, which is still calculated and planned with the help of the little drill. If it weren't for the fact that the little drill hadn't entered the brain domain to evolve and had his own sword pill to assist in calculations, these steel structures would have been more perfect.

Glancing at the workplace, Ye Yu muttered, "Why do I feel that my progress has slowed down?" ”

"Is there one?" Ah Fei silently looked back at the back of his head, "I can't see it." ”

"Let's go, go over and have a look!" Ye Yu led Ah Fei towards the construction site quickly. As soon as they approached the construction site, they heard the sound of a leather whip.

"This little bastard dares to run! Lao Tzu won't kill you today! A man shouted rudely, Ye Yu and Ah Fei turned a corner, only to see a man in the uniform of the Long Xiang Guard's outer army wielding a whip and whipping a skinny little boy.

This little boy is so thin and weak, it is terrifying to watch, Ye Hao has seen some photos of hungry people on the Internet before, they may not be as scary as children, almost a thin layer of skin is attached to the bones, the little boy's body is not much different from a skeleton, his head is a little big, it is obviously a sign of malnutrition, and wrinkles have appeared on the skin that should have been tight. The whip whipped at him, leaving bloody scars in his wake.

The little child is like a demon crawling out of hell. Ye Hao's heart trembled, even though he had experienced so many killings, he was still shocked by the scene in front of him.

"Stop fighting, please stop fighting." A thin old man pounced on him and took the child in his arms, his upper body and lower body surrounded by a simple leaf braid, and there were many blood marks on his body.

"Fuck off! Old guys! I'll teach you a lesson later! The dragon guard kicked the old man away with one kick and raised the whip again. As soon as he raised his whip, he felt a loosening in his hand.

"Grass mud horse, who dares to ......" He turned his head scolding, and when he saw Ye Yu, he suddenly bent his knees, knelt down with an ordinary sound, and kept kowtowing. Small...... The villain doesn't know that His Majesty has arrived, please forgive your sins, please forgive your sins. ”

"Why did you hit them!" Ye Yu threw the whip aside, forcibly suppressing the anger.

When the sergeant heard this, he hurriedly shouted: "Your Majesty doesn't know, this old man was originally here to do work, who knew that he was lazy and lazy, lazy and slippery, he is a little bastard, he went to steal our supply of green buns all day long, and today I was finally caught, so I ......"

Ye Yu turned his head to look at the little boy, the latter's eyes flickered slightly, and Ye Yu immediately realized that he had indeed stolen something.

But...... Looking at the little boy's appearance, Ye Hao felt that the words were in his mouth, he squatted down and wanted to touch the little boy's head, but the latter immediately retreated in cringe.

"Has the progress of the construction of the city wall been slowing down recently?" Ye Yu asked suddenly.

"Yes," the sergeant immediately complained, "these wilderness vagrants, one is lazier than the other, one is more cunning than the other, they take the green bun and don't do anything, or they just pretend to do something, Your Majesty, don't look at them one or two miserable, they are really lazy, and they can make you angry to death!" ”

The sergeant obviously held back for a long time, and poured bitter water in front of Ye Yu a little uncontrollably, chattering endlessly.

"That's it!" Ye Yu stood up and stopped the sergeant's words, and at this moment, there was only a tingling in his heart.

Are the sergeant's words true? There is certainly an element of exaggeration, but the truth is ...... Maybe it really is.

Ye Yu let out a long sigh, what could he say? Punish the sergeant? Or is it a meal for these two people? None of this made any sense, and Ye Yu suddenly felt that some things could not be solved by just building a city.

Half of the backbone of humanity, which has been forged by thousands of years of struggle, has been broken!
