"Second brother, let me talk to you again. Your words make me very worried." After a while, after Li Er's mood calmed down, Empress Changsun once again brought up the old story.

"Okay, okay, you, I'm really worried about your children. I just hope they can understand it!" Comrade Li had no choice but to talk about this wife who grew up with her since childhood. In desperation, he had to talk about the afternoon from beginning to end.

"My second brother has half a month later (accepting the advice of a book friend and adjusting the cement usage time) really wants to take the court officials over to see it? I have never heard of anything that can build a bastion in such a short time." After listening to Li Er's story about Changsun, he was even more worried.

There were so many court officials present, and if Li Chengqian did not fulfill his promise, it would be a shameful thing, and the crime of deceiving the emperor would not be able to escape.

"Don't worry, Guanyin maid, have you seen that kid do something unsure? And even if he can't finish it, he can teach him a lesson." Seeing Changsun's worried look on his face, Li Er began to regret saying too much to her and couldn't help but persuade him.

"Is it really okay?" Changsun asked seriously.

"Don't worry, then all the people who go to Tiance Mansion will be old people. Even if that kid fails to complete, there will be no big problems." Li Er said in a vow, looking exactly like Li Chengqian.

Finally, I found the reason why Li Chengqian likes to swear.

"I hope so." Empress Changsun said a little lost.

Changsun was worried, and Li Er was confused while expecting. As time passed, the two began to care more and more about Li Chengqian's movements.

Sand, cement, gravel and wooden boards, all the materials used by Li Chengqian made Lao Li feel unfamiliar, but since he had been talking for half a month, Lao Li just ignored it. Anyway, this guy is not the first time this inexplicable thing.

Li Chengqian no longer cares about the construction of the house, and the castle of the concrete structure is the most important.

Huge foundations were dug out, and wooden boards were put together in the shape of boxes, and then formed a prism.

The sand, cement, stones and water were fully mixed and poured into the middle of the boxes. In addition, countless long wooden poles were inserted into the middle of the poured concrete, and the patrol guards who were caught by Li Chengqian were responsible for the shock and pounding work.

The entire Zongzheng Temple was turned into a huge construction site by Li Chengqian. It was constructed day and night for four days and four nights, and then suddenly everything stopped.

Countless workers evacuated from Zongzheng Temple almost overnight and the palace.

Only a huge wooden box was left in Zongzheng Temple, and the other one was the large blue brick building that Li Chengqian had built. Of course, Li Xiaogong's office was still there, but it was already surrounded by wooden boxes and could not be seen.

Li Er came to see it once after the shutdown, but finally shook his head and left in confusion.

He couldn't understand what was going on in the "health period" and didn't know why a bastion still needed to maintain health.

Time passed, half a month passed in a flash. During this period, except for the seventh day after the craftsmen evacuated, no one had ever taken care of the huge gray castle.

"You guys hurry up and keep up, it's really a waste. Cheng could carry two broken things when he was young." Following Li Er, Cheng Yaojin turned around and urged the men carrying the crossbow in contempt.

This old man had long heard that he would test a bastion built in half a month, so he dragged out two crossbows from the Right Martial Guard early on, claiming that he would let Li Chengqian show his face.

"Old Cheng, can you be more shameless? The prince is your junior after all. After all, you built a battalion and you actually used a crossbow to experiment." As Li Chengqian's uncle, Chai Shao's words mostly favored Li Chengqian.

"You are still a general. Don't you know there is no joke in the army? If the two armies can still show mercy in front of the enemy army? Besides, Lao Cheng trusts the prince. He knows that the boy never speaks big, and he says there is no problem, then there will be no problem, so he uses this to support the scene."

Old Cheng said a lot of nagging, saying all good and bad things, and doing all good and bad things. His shameless style was even better than that of the beginning. Chai Shao was so angry that he left a vicious sentence, "Old man" and turned around and left.

Listening to the conversation between the two behind him, Lao Li, who was walking in front of him, chatting with Changsun Wuji, a hint of pride flashed in his eyes. Old Man Cheng was afraid that this time he would be embarrassed.

The day before yesterday, Lao Li went to see the castle. The gray integrated building under the night sky was like a crawling giant beast, and he had to choose people to eat at any time.

The building is a whole. Lao Li fumbled on it for a long time but couldn't find a gap. To be on the safe side, Li Er asked the "Qi Tian Da Sheng" to shoot with the four stone bow once, but there was no effect except leaving a white dot on the wall.

The castle made Li Er very satisfied. He even thought that what Li Chengqian said was a bit conservative. For the Tang Dynasty, this cement was not only beneficial to the country and the people, but also a weapon for the country.

With this thing, the deserts in the northern desert of the Desert and the Western Regions are no longer the forbidden area of ​​the Tang Dynasty. The bastions that watch over each other can extend the tentacles of the Tang Dynasty to anywhere on this continent.

But... it's a bit awkward to put such a military building in the palace. And it seems that since Qin Shihuang, I have never heard of any emperor building a bastion at his home, so he has set a precedent.

"Your Majesty looks confident, I'm afraid he's tried it in advance?" Changsun Wuji and Li Er had an extraordinary relationship and spoke much casually.

"It's hard to say, you'll know it when you're here and you'll see it." Li Er smiled mysteriously, intending to surprise these old guys in a while.

The old man was very curious and also planned to see what the bulwark that could make Old Li Zhi proud would look like. Judging from his performance of not stopping Cheng Yaojing from taking the crossbow, this was clearly full of confidence in the bulwark.

After going around, it was not long. After turning around a palace, a huge gray building covering an area of ​​about two acres and three acres of grey finally appeared in front of a group of old people.

"This...this..." Looking at the huge building, Changsun Wuji was the first to be stunned.

"My mother, this is a stone." Old Yuchi blinked his cow's eyes and exclaimed in surprise.

"Uh~." Lao Cheng didn't say a word, and all his sighs were replaced by the word "Uh".

The rest of the eyes were twitching, and they were speechless.

The Tang Dynasty rustic bullies who saw concrete buildings for the first time were completely shocked. Their performance was no less than the dandy who drove the '212 Jeep' every day and suddenly saw a 'Knight 15th'.

"Chengqian has met his father and uncles." From afar, Li Chengqian, wearing a suit similar to a practice suit, stood in front of the "Black Brick House".
