"Boy, you're not going to be a good thing, are you?" When everyone walked up to Li Chengqian, Cheng Fairy asked aggressively.

"Uncle came with a bed crossbow, whether it is a good thing or not, you will know if you try it." Looking at a few strong men who were fiddling with the bed crossbow, Li Chengqian said with a light smile.

"There's no hurry, but this house behind you looks strange, and it's also made of cement?" Cheng Fairy couldn't understand Li Chengqian's depth, and he didn't plan to test the bed crossbow before Li Er spoke, so he changed the topic and said.

"Exactly." Looking back at Lao Li and Li Xiaogong, who had already slipped into the room, Li Chengqian nodded and replied.

"Can I go in and have a look?" Although Cheng Laoxiang was asking, he had already walked towards the house under his feet.

Li Chengqian, who was helpless, shook his head, gestured to Li Jing, Qin Qiong and the others who came with Li Er, and took the lead to walk towards his big blue brick house.

It's like bandits entering the village, bears and blind men entering cornfields, and the old people who are extremely curious about Li Chengqian's blue-brick and tiled house have been constantly tossing around in the room.

Knocking on the wall, stomping on the ground, the most terrible thing is Cheng Lao, the girl is actually holding her arms and hitting the wall vigorously, quite a bit of a frame that does not hit the south wall and does not look back. But in the end, the old man gave up on this stupid practice, rubbed his shoulders and ran to the side to lick his wounds.

It is close to the 500mm thick brick wall of later generations, not to mention that Lao Cheng hit it with his shoulder, or he smashed it with a sledgehammer, and it took some effort to smash it through.

"Prince, come here." Just when Li Chengqian snickered at Lao Cheng's inadequacy, Li Er's voice came.

"Father, are you looking for me?" Running to Li Er, Li Chengqian said with a salivating face.

"This ground is the same as that wall?" Lao Li stepped on the ground with his feet and gestured in the direction of the fortress with his eyes.

"Yes, it's all the same." Li Chengqian nodded.

Then, just as Li Er was about to continue to say something, the loud sound of "Boom ......" accompanied by a slight tremor made everyone look in the direction from which the sound came from.

I saw Cheng Laoxiang leaning against the wall, holding a Xuanhua axe in his left hand, and his right hand was constantly shaking with porcelain teeth, and there were some broken blue brick powder on the ground under his feet.

"Old horseman, what kind of demon moth are you making trouble with?" Comrade Lao Li was obviously frightened by Fairy Cheng, and shouted angrily.

"Your Majesty, didn't you say that you came today to test whether the wall is strong?" Cheng Lao Pifu's face changed faster than turning a book, and as soon as Lao Li's voice was alive, the old man muttered with an aggrieved face.

"Fart, I'm asking you to try the fortress, not demolishing the house." Lao Li was almost jumping on his feet and roaring.

Ya is really annoying, just hit the wall with his shoulder, and now he actually uses an axe to chop, Lao Li, who has fought all his life, has never heard of anyone who uses an axe to cut the city wall.

"Oh, I'll try it." Cheng Laoxiang shrank his neck when he was scolded, dragged the axe and left, but when he arrived at Li Chengqian's side, he dragged him out of the room.

"Boy, is there any cement left? Get some for me Lao Cheng. Outside the room, the voice of the old man came in, and Li Er, who was listening, gritted his teeth, and wanted to take out a horizontal knife and stab him.

"Yes, but the little nephew is also a small business, and the uncle wants to, so he has to pay some costs, right?" Li Chengqian's equally shameless voice also sounded outside, making Lao Li hang his head quite weakly.

I feel that Li Chengqian should not be allowed to have more contact with that old man, and he must be fireproof, anti-theft and anti-goblin in the future, otherwise his own children will bring damage to this old man.

"I also need money for some cement in Lao Cheng?" Fairy Cheng asked with a glare.

"The little nephew is also thinking about the uncle, otherwise others will think that the uncle is clever and robbing, and he is forced to buy and sell, which is also detrimental to the uncle's reputation!" was stared at by Lao Cheng a lot, and Li Chengqian had some immunity.

"Boy, there's really a kind!" Cheng Fairy gave a thumbs up and ignored Li Chengqian.

He looked up and yelled at the men who were fiddling with the bed crossbows: "Little ones, is the bed crossbow set ready?" The prince's fortress is still waiting for our right guard to experiment. ”

"General, it's already debugged!" A man who seemed to be on fire replied.

"Then what are you standing there for? Aim at the gray stone and shoot at Lao Tzu. Lao Cheng seemed to want to vent all his dissatisfaction with Li Chengqian on the fortress, and he seemed to grit his teeth when he gave orders to the man.

"Well, follow the general's orders." After the man agreed, the characteristic "crunch" sound began to sound when the bed crossbow was hung on the strings.

"Let's go, let's see." The sound of chaotic footsteps sounded, and the old goods came out of the room one after another, standing in front of the big brick and tiled house, looking at the direction of the fortress from afar.

Just now Lao Cheng cut on the wall as a result of the old goods are in their eyes, at this time the confidence in the fortress is much stronger, even if this fortress can reach the strength of the current city wall, the military also talks about the full use, after all, the use of this cement can save time to build the city.

The hammer was smashed, and the bowstring trembled with a "buzz", followed by a "bang", and the arm-thick crossbow bolt slammed into the gray wall of the fortress.

In an instant, the scene that made everyone dumbfounded happened, and the crossbow arrow that should have been inserted into the wall in the original impression actually crashed into the air, rolled and flew into the distance, and smashed to the ground.

"Keep shooting." Li Er's eyes flashed with excitement, as if he had seen the scene of the northern grassland of the concrete fortress, as if he had seen those nomadic cavalry crashing into the fortress like waves crashing into the reef.

"Bang, bang, bang" The sound of the bed crossbow sounded again and again, crossbow arrows, siege chisels, and all kinds of long-range siege weapons were constantly put into use, and they were tossed until two hours later.

"Alright, let's stop." Li Er, whose excitement had diminished slightly, waved his hand and stopped this futile experiment.

"What's wrong with this thing?" Looking at a section of the wall that was being taken care of, Li Er asked Li Chengqian.

"Huge vibrations, such as trebuchet attacks, and the other thing is that you can only build a city in the summer, and in the winter because the water freezes, and the cement doesn't work at all." Li Chengqian also looked at the gray fortress, thought for a while and said.

"Your Majesty, this is good enough, much stronger than our current walls. And saving time is the biggest advantage of cement, and the degree of robustness is just a bonus. The eldest grandson Wuji, who had never spoken, took over Li Chengqian's words.

"Yes, yes, I almost forgot the purpose of this experiment." Lao Li pondered for a while, and felt as if he had forgotten what the purpose of coming here was, so he couldn't help but laugh at himself.

"I think we can build a section of the city wall outside the city and continue the experiment." At this time, Li Jing had already run to the side of the fortress to pick up some concrete fragments and came back, put them in his hand and said playing.
