The newly built city walls are indeed wood, and large pieces of wooden boards are pieced together, which looks... very neat.

The old guys followed Li Er and admired the wooden wall that Li Jing spent a month driving out and said nothing.

Killing people is just a lie. Everyone is a minister in the same palace and usually eats, drinks, and calls brothers. If you take advantage of the situation at this time, you will be unkind.

After a long time, the old man Cheng Yaojing laughed dryly behind Li Er: "That..., this wall looks quite strong. It's not easy to make it like this in a month, haha, not easy."

"Well, it's pretty good." Li Ji agreed awkwardly.

"It's not bad. You can even remove it after the competition, so as to save waste." Chai Shao took over the conversation.

Li Jing's expression was calm, without any sorrow or joy, and he was with Li Er like nothing was wrong, as if everything had nothing to do with him.

At this time, Changsun Wuji also regretted that he was too impulsive at the beginning, and the disaster was not as good as his family. Besides, it was not all Li Dejian's responsibility to join the army. He was all adults, and he should always have his own ideas when encountering problems. He should not follow the crowd.

The atmosphere was a bit dull, and the old guys didn't even want to chat awkwardly, staring at the wooden walls one by one and silent.

Li Jing came to the so-called city wall at this time and introduced quietly: "Your Majesty, my colleagues, this city is 568 steps long, three or two feet thick, two feet high, and there are four horse roads and two city gates. Since the construction started twenty-five days ago, it cost 1,400 stag, 2,400 manpower, and 200 cattle and horses in total."

Everyone: "..."

It's over, right? I admit that I was a bit unauthentic before, but you, Li Jing, can't do this either.

Isn’t it just a wooden city wall? What kind of achievements are used to show? Your Majesty is still here. Is he trying to sell his misery?

Li Er naturally knew that Li Jing was cheated by him, and he felt a little uncomfortable when he looked at the wooden city wall, but with Li Jing's introduction, the imperialist leader began to feel uncomfortable.

The so-called king is the leader of the minister. If the king calls the minister to die, the minister has to die. What's wrong with me? Even if I'm wrong, you don't have to humiliate me in public.

At this moment, Li Er's face sank: "Pharmacist, I want to know, since there is a horse path in the city wall you supervised, I wonder if there is a horse on it?"

Li Jing smiled slightly: "Your Majesty is a little restless, I haven't finished speaking yet." After saying that, he waved to the craftsmen waiting not far away: "Come here and open the template."

What template? What to open? Is there something in this wall?

Seeing several craftsmen coming with crowbars, the imperial guards who were accompanying him came to Li Er and protected him behind him.

The other old guys scattered to both sides and stood in a row, intending to see what was behind the wooden boards.

Several craftsmen were moving very quickly, and crowbars pointed at the gap between the wooden boards and pried hard. With the sound of "squeaking", a wooden board that was not much smaller than the city gate was pried off, revealing the blue-gray wall inside.

The old guys couldn't help but frowned. No one knew what was behind the wooden board. Could it be really a city wall?

This is impossible. No matter the money spent, the labor spent, or the time spent, it is not enough to build such a wide city wall.

Maybe it's just some special locations, it doesn't seem like a pen. It's impossible that the huge city walls are all made of wood, and it's reasonable to have a little stone.

Cheng Yaojin has always been a pioneer. He went up and patted the blue-gray wall twice, turned around and grinned and said, "No, very strong, Li Jing, you are so powerful."

Li Er rolled his eyes. Old Man Cheng's play was too fake, and the intention of pleading for Li Jing was too obvious.

Li Ji and Qin Qiong also came up. They were more serious and looked around the blue-gray wall. After a suspicious look at each other, Old Qin took a crowbar from a craftsman and looked at Li Jing.

The meaning is very obvious, I want to try it, no.

Li Jing nodded slightly, still with a lukewarm expression.

Since that's the case, what are you waiting for? Qin Qiong and the second brother of Qin held a crowbar in his hand. With a sudden force, Qin Qiong was shocked and his palms were numb. Looking at the blue-gray wall, there was only one white dot.

Cheng Yaojin was stunned: "Why is this wall so strong? My second brother is extremely brave. Even the city wall in Chang'an cannot stop him from poking. Why is there only a white dot on this wall?"

Yes, how is this possible? What exactly is this wall made of? Is it steel?

No, if it is steel, it should be very loud.

The old guys looked at each other and looked at Li Jing one after another. Even Li Er was shocked and came down from the horse, came to the front of the blue-gray city wall, tried to touch it with his hands, patted it twice, and asked in wonder: "Pharmacist, why is this city wall so strong? Could it be that you have used some immortal magic?"

Because he was too shocked by the solidity of the city wall, Li Er forgot to be angry at this moment.

"Your Majesty, this wall is made of concrete, and its strength is comparable to that of gold and stone, and it is actually an indispensable thing for building a city." Li Jing finally showed a smile on his face: "

"Concrete?" Li Er frowned, a new term.

Li Jingyu said proudly: "Oh, concrete is the result of my son Dejian's painstaking efforts and studying hard for several years. He was planning to present it to Your Majesty in front of the emperor, but he was afraid that there would be nothing to say, so he used it here."

Li Er blinked his eyes, and was weeping again. He studied hard and thoughtfully. If you, the Li family, there are no other words available, right? Both the father and son are all in this set of words.

Besides, your son is so fucked, and he doesn’t have the appearance of two taels of flesh all over his body. He is always crying and bleeding, so he is not afraid of vomiting blood and dying?

Nodded: "Dejian is really a talented child, and I will not lose to him. But the pharmacist, such a magical object must have cost a lot of manpower and material resources? Can this section of the city wall be built with this object? How much does it cost?"

"This..." Li Jing was a little embarrassed and looked at the city wall and didn't know how to answer.

Cheng Yaojin was impatient and couldn't help but urge, "Oh, what's the one here? Li Jing, tell me quickly, how much money it cost and how many geniuses it took to build this wall."

In front of everyone, Li Jing raised his hand and pointed to the city wall, and said in a very intriguing tone: "It took 1,200 guan, twenty-five days, two thousand four hundred labor, and two hundred cattle and horses."

Li Er was a little unhappy after hearing this: "You don't need to say this. I know that you used a total of 1,200 stagnants of this city wall, which took twenty-five days and worked..."

Halfway through, Li Er suddenly stopped his eyes and stared at him like a lantern, and pulled Li Jing: "Master Li, you, you shouldn't want to tell me that this whole wall... is all built by this thing!"

Not only Li Er was shocked, but also the old guys were shocked.

If the city walls built in twenty-five days are as strong as those of Qin Qiong’s position just now, then this concrete will really become a magical object.

Finally, Li Jing spoke and said in a very hated tone: "Yes, Your Majesty, this entire city wall is made of concrete. If your colleagues don't believe it, you can give it a try."

Just try it, who is afraid of whom.

As long as they were able to use swords and guns, the old men scattered and grabbed a few craftsmen: "Disassemble, all the wood is demolished, I want to see if this wall cannot be smashed."

One or two, a group of old guys were scattered within more than 500 steps under the city wall, either using hammers, crowbars, knives and axes. In short, all the big guys who could use were used were used and he tried his best to greet the city wall.

Eighty, eighty, and a quarter of an hour later, dozens of some sledgehammers were exhausted and panting, shaking their heads, saying they could do nothing to the city wall.

To be honest, concrete is indeed not something that humans can fight against, especially when the thickness reaches a certain level.

All the wooden boards outside the entire city wall have been demolished, and the original yellow dragon turned blue-gray. Li Er stood at the top of the city with great enthusiasm and shouted to the sky: "God blesses the Tang Dynasty. If you get this magical object, I will have no worries about everything in the Tang Dynasty."

All the old men bowed together: "Your Majesty is full of blessings, auspiciousness comes from heaven, and the Tang Dynasty, and thousands of victories!"

"Hahaha... all the good guys are calm!" Li Er was in a good mood, and did not care about Li Jing's previous rudeness, and took his hand and walked side by side on the city.

There is no way, the son is good, but I am not convinced by my son's fortune? You can also give birth to a son who can develop cement.

A month ago, Li Jing lived a life with the jokes of the old guys. He was in power today and smiled like a flower.

As for chasing Li Hao with a big stick, he ran all over the yard...

Hey? Is this happening?

No, if there is, it will be a filial son. Just imagine, if he doesn't use a big stick to beat that bastard, how could he have such a good thing?

The more Li Jing thought about it, the more he felt that it was very correct. Before he knew it, his hands began to itch again. Why don’t he go home and beat that kid again.

The old guys who originally felt a little sorry for Li Jing no matter how they looked at Li Jing, they felt that this guy was disliked. People were more than people, and they had to throw away goods. The old guy didn't know which incense stick was burned right, but his son actually had such a big future. How could this mud horse make people live?

There is also this city wall. This thing is so strong that it has become a cheating tool during the competition of the entire army? No matter who comes to defend the city, it will be a situation where you can win or lose.

The Li family and his son are really cheating. If they had known this, they would not have given him the work of building the city walls.
