"Second brother, let's talk to the concubine again, your words make the concubine very worried." After a while, when Li Er's mood eased a little, Empress Changsun once again brought up the old matter.

"Okay, well, you, it's really heartbreaking for your children, I just hope they can understand something!" Comrade Lao Li had no choice but to talk about the incident from beginning to end with his wife, who had grown up together since childhood.

"After half a month, the second brother (accept the suggestion of the book friend and adjust the use time of the cement) really want to bring the courtiers over to see, the concubine has never heard of anything that can build a fortress in such a short time." After listening to Li Er's story, the eldest grandson was even more worried.

With so many courtiers present, if Li Chengqian did not fulfill his promise, it would be a small matter of losing face, but this crime of bullying the king could not be escaped.

"Guanyin, don't worry, have you seen that kid do things that you are not sure of? And even if he can't finish it, he can learn a lesson. Seeing the eldest grandson's worried face, Li Er began to regret talking to her too much, and couldn't help but persuade him.

"Are you really alright?" The eldest grandson asked seriously.

"Don't worry, all the people who will go to Tiance Mansion will be the old people of Tiance Mansion at that time, even if that kid can't finish it, there will be no big problem." Li Er said solemnly, and his appearance was the same as Li Chengqian.

finally found the root cause why Li Chengqian likes to swear.

"I hope so." Empress Eldest Sun said with some distraction.

The eldest grandson was worried, Li Er was confused in anticipation, and 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 said that it had been half a month, Lao Li simply didn't care, anyway, it was not the first time that this bastard boy had done such an inexplicable thing.

Li Chengqian didn't care much about the construction of the house, and the concrete structure of the fortress was the most important.

Huge foundations were dug out, and wooden planks were put together in the shape of boxes, which were then formed into a fortress.

Sand, cement, stones, and water were thoroughly mixed and poured into the middle of the boxes, and countless long wooden poles were inserted into the middle of the concrete, and the patrol guards who had been caught by Li Chengqian were responsible for the shaking work.

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

Countless workers evacuated the temple and the palace almost overnight.

There is only a huge wooden box left in Zongzheng Temple, and the other is Li Chengqian's blue brick and tile house that has been built, of course, Li Xiaogong's office is still there, but it has been surrounded by wooden boxes and cannot be seen.

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

He didn't understand what the 'recuperation period' was, and he didn't know why a fortress still had to maintain health.

Time passed, half a month passed in a flash, and no one took care of the huge gray bastion except for the seventh day after the craftsman withdrew.

"Hurry up and keep up, it's really a waste, this broken thing Lao Cheng could carry two by himself when he was young." Following behind Li Er, Cheng Yanjin turned around and urged a few men carrying bed crossbows with disdain.

This old man had already heard that he was going to test a fortress built in half a month, and he dragged out two bed crossbows from the right guard early, and claimed to let Li Chengqian show his face well.

"Lao Cheng, can you be more shameless? The prince is your junior after all, build a fortress, and you even took a bed crossbow to experiment. Chai Shao, as Li Chengqian's uncle, is mostly biased towards Li Chengqian.

"You're still a general, don't you know that there is no joke in the army? If the two armies are in front of the formation, can they still let the enemy show mercy? Besides, Lao Cheng trusts the prince, knowing that the kid never says big things, he says that if there is no problem, then there must be no problem, so he will use this to support him."

Lao Cheng chattered a lot, all the good and bad things were said, all the good people and bad people were done, and his shameless demeanor was even better than at the beginning, and the angry Chai Shao viciously dropped a sentence of 'old horseman' and turned around and left.

Listening to the conversation between the two behind him, Lao Li, who was walking in front and chatting with the eldest grandson Wuji, flashed a trace of arrogance in his eyes, and Cheng Lao Pifu was afraid that he would be embarrassed this time.

Lao Li had been to see the fortress the night before, and the gray one-piece building under the night was like a creeping giant beast, ready to be devoured at any time.

The building is completely a whole, and Lao Li groped with his hands on it for a long time and did not find a single gap. To be on the safe side, Li Er asked the 'Monkey King' to shoot once with a four-stone bow, but it didn't have any effect except for leaving a white spot on the wall.

The fortress made Li Er very satisfied, and even he thought that what Li Chengqian said was a bit conservative, this cement is not only for the benefit of the country and the people for Datang, but also a weapon for the country.

With this thing, the Mobei Grassland and the Western Desert are no longer the forbidden places of the Tang Dynasty, and the fortresses that watch and help each other can completely extend the tentacles of the Tang Dynasty to any place on this continent.

Merely...... It's a little awkward to put such a military building in the palace, and it seems that since Qin Shi Huang, I haven't heard of any emperor building a fortress in his own house, and this is a precedent.

"Your Majesty seems to be confident, I'm afraid that he has tried it in advance, right?" The relationship between the eldest grandson Wuji and Li Er is extraordinary, and they talk a lot more casually.

"Don't say, you'll see it when you get there." Li Er smiled mysteriously, intending to surprise this gang of veterans for a while.

With a strong curiosity, the old man also planned to see what the fortress that could make Lao Li Zhi proud was like, judging from his performance of not preventing Cheng Fairy from bringing the bed crossbow, this was clearly full confidence in this fortress.

After going around a palace, a huge gray building covering an area of about two or three acres was finally presented in front of a group of old goods.

"This ...... This ......" Looking at the huge building, Eldest Sun Wuji was the first to be a little dumbfounded.

"My mother, come on, this, this is a stone." The old lieutenant blinked in amazement with a pair of bull's eyes.

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

The rest of the people twitched from the corners of their eyes, and they didn't know what to say.

The Tang Dynasty turtles who saw the concrete building for the first time were completely stunned, and their performance was no less than that of the people who drove the '212 jeep' through the city every day, and suddenly saw a 'Knight XV'.

"Cheng Qian has seen his father and uncle." In the distance, Li Chengqian took the 'bald king' and Wu Chen, wearing a suit similar to a practice uniform, and stood in front of the 'blue brick and tile house'.
