The concrete fragments that Li Jing brought back were passed back and forth in the hands of everyone, during which except for Lao Cheng who bit his teeth with his teeth, the observation methods of others were very normal.

"Your Majesty, why don't we go and see the outer wall of the fortress?" Datang's tactics of relying on bed crossbows to embed siege chisels into the city wall, and then letting soldiers climb and climb the city, fell short in the face of the fortress, and none of them could be embedded in the outer wall of the fortress, which made everyone curious.

Although they had seen the concrete fragments, they still couldn't understand what the façade looked like.

And everyone also wanted to know how thick the exterior wall was, and what it looked like after an attack.

"Go together, go together, and the prince will come too." Lao Li said with a smile.

He had seen it the night before yesterday and knew that the outer wall was no more than two feet at most, which was much thinner than the current city wall of the Tang Dynasty, so now Lao Li was looking forward to seeing the second surprise of the ministers.

A group of people, led by Li Er, walked towards the fortress with a hula la, accompanied by the bargaining sound of Cheng Fairy's broken gong, after seeing the defensive power of the fortress, he was even more obsessed with cement.

"Your Majesty, this, this wall is only less than two feet thick?" Chai Shao turned around three times inside and out, and finally asked suspiciously.

"Well, it's much thinner than the current city walls of my Tang Dynasty." Duan Zhixuan watched it with Chai Shao, and also echoed it together.

"What is that, didn't you see the wall just now? The biggest trauma is only the size of the bowl. "It's better for the old lieutenant to show off his eyes.

"This cement is really a good thing, building a walled castle is fast and strong, it is better to build a road wall to enclose the Turks." I don't know if the second person said this, but it is very likely that Cheng Lao is the old goods, and no one can come up with such an idea except him.

All kinds of exclamations finally satisfied Li Er, and the 108,000 pores on his body were all relaxed, and Li Chengqian's gaze softened a lot.

"Hejian, this place for you to work is good, it's really safe." Entering the 'office' of Li Xiaogong, who was surrounded by the fortress, just sat down, Wei Chi said with a grin, causing everyone in the room to laugh.

"You like to send you." Li Xiaogong rolled his eyes and said.

Last time, he was accused of rebellion because he built a stone town outside where he lived, and now this unscrupulous old man has a psychological shadow.

"Okay, okay, let's stop. You've also seen the effects of the fortress and cement, so tell me what you think. Lao Li knocked on the table with the pen holder on the table and said.

The whole process made the expression on the face of Li Xiaogong, the king of Hejian County, twitch again and again, for fear that Lao Li would break his pen holder.

"Your Majesty, what else is there to say, one in ten miles, the fortress is built all over the grassland, and when the time comes, see how those Turks still graze." Cheng Laoxiang was the first to respond to Lao Li's call, stood up to express his opinions, and firmly believed that his idea was the most correct - to enclose the grassland.

"Nonsense, didn't you hear the prince say, does this concrete need stones? It's all over the grassland, where do you get your sand and stones? Is it transported from Longyou to the grassland? Chai Shao interjected coldly on the side.

"So what do you say to get it? If you don't have such a good thing to build a fortress, why keep it? Leave it at home to have a baby? Lao Cheng, who was rejected by Chai Shao, stared at him, and immediately took out a state of preparing to fight.

"According to a certain family, all the walls should be bulldozed, and all of them should be rebuilt with this mud." The old lieutenant didn't wait for Chai Shao to speak again, and rushed up to express his opinion.

"Nonsense, who will be pushed to build the city wall? Mobilize the people? Do you want to start a riot like the end of the Sui Dynasty? Li Jing said unhurriedly on the side.

"This doesn't work, that doesn't work, so what do you say?"

"I think the prince's house is good, it's better to use it for people's livelihood construction first." Fang Xuanling, who hadn't spoken much, said.

"How can this be, cement, a weapon for building cities, must be used in the military." Although Chai Shao and Lao Cheng are together, if you really want to talk about use, he still has the same opinion as Lao Cheng, it must be military.

"Shut up. The cement was studied by the prince's Carboniferous Division, so let the prince talk about it. Lao Li continued to knock on the pen holder that made Li Xiaogong's flesh hurt, and the unscrupulous old man who saw it not only twitched his face, but also kept twitching his body.

"Build roads, if you want to get rich, build roads first." Li Chengqian almost didn't think about it, and opened his mouth to say.

As a result, the voice fell in exchange for Lao Li's big brain: "Rebel, am I short of your flowers?" Open your mouth for money, shut up for money, what kind of system! Again! ”

Looking at the old people who were smiling, especially the old goblins who were squeezing their eyebrows, Li Chengqian felt that the old man was jealous that his brain was too smart and wanted to beat himself stupid.

But the old man is an old man after all, and if he fights, he will fight, rubbing the back of his head that is faintly painful, Li Chengqian said with a pout: "The road is repaired, which can increase the speed of the march and facilitate the supply of logistics." Is that okay, Father? ”

"Not bad." Lao Li nodded, and said that he was satisfied, looking like he was taking the school Li Chengqian.

"Isn't there still no one to build roads, you can't recruit people, and no one is doing this work." The old lieutenant was rarely smart.

"Prince, go on." Comrade Li turned his gaze to Li Chengqian, as if Li Chengqian was a roundworm in his stomach.

Many of Datang's projects that require a lot of labor are in a state of suspension, in order to recuperate, but also to reduce the burden of the people.

In such a situation, Lao Li also couldn't solve the problem of labor, so this arduous task was once handed over to Li Chengqian, who was 'far away from the rivers and lakes'.

looked at his old man pitifully, trying to make himself look more cute, but in exchange for a 'you can't do it' look.

With a deep sigh, Li Chengqian looked at the several generals of the Sixteenth Guard who were seated, and only said after a while: "This worker's problem still needs to be solved by being listed as an uncle." ”

"Cheng Qian, this joke can't be made, the sixteen guards are stationed in important places in Gyeonggi, and they can't be arbitrarily adjusted. Your farm is on the edge of Chang'an, and there is no problem for everyone to allocate some people to help you, and the road construction can't be done according to the rules. Without waiting for others to speak, Chai Shao spoke out and vetoed Li Chengqian's proposal.

Even Li Er stared at Li Chengqian with a somewhat unkind face, thinking that his idea was bad enough.

However, Li Chengqian had no intention of stopping, jumped down from his chair, and under the gaze of a group of old goods, he said unhurriedly: "Who said that the soldiers of the Sixteen Guards were going to be moved? ”
