"Father, why are you here?" For Li Xiaogong, who rushed over, Li Chengqian flashed his body and let him in, so that he had time to face Li Er.

"Say, what are you tossing again!" Looking at the Zongzheng Temple in front of him, Comrade Lao Li was gasping for breath, and asked with his eyes glaring.

There are so many people running around the palace, transporting sand for a while, and boards for a while, as long as they are not fools, there is nothing that they can't notice, how can they not come and see if they notice.

Since Li Chengqian was locked up, he has not heard the news of his tossing for more than half a month, which makes Lao Li more or less unaccustomed to it. I was thinking about asking Li Xiaogong, how was Li Chengqian's life in Zongzheng Temple, I never thought that I had just gone down to the court, and when I left the hall, I saw craftsmen who were busy transporting materials.

With a certain premonition rising in his heart, Lao Li decisively followed the craftsmen, intending to verify his guess, and the result was ...... The scene can be described as frenzied.

Zongzheng Temple, which was fine a few days ago, has become miserable in half a month.

Bricks and rubble were everywhere, the largest room had been demolished to the ground, and the courtyard walls were almost all gone, turning into broken bricks piled together.

"Father, Uncle Hejian said that Erchen has no hope of going out this year, so Erchen plans to pack up and prepare for winter." Li Chengqian glanced at Li Xiaogong, who was running around in the yard, and said to Li Er.

"Winter? It's only summer and you're ready for the winter? Then I will reward you with two sets of fur furs to wear now. Lao Li said with an ugly face, and he didn't take Li Chengqian's stubble to tell Li Xiaogong at all.

"Uh~, I don't need this." Li Chengqian said embarrassedly, if you get a fur coat to wear in this summer, it will heat people to death.

"Not really? I see it very useful! And you see for yourself what you're wearing, what kind of mess you look like, and whether you look like a prince. The more Lao Li spoke, the more angry he became, and a finger was about to pestle on Li Chengqian's head.

"Father, this dress is something that the retainer is experimenting with, and it is cool to wear in summer. If it weren't for the fact that the sons couldn't get out, they would have thought about making a few sets for you and your mother to send over! Leaning back with his body and pulling on his clothes, Li Chengqian said aggrievedly.

"Don't pretend to be pitiful to me, and say what the hell are you trying to do." Li Er pointed to the mess behind Li Chengqian and asked.

As for dressing, Lao Li just said a word, the Tang Dynasty is open, and he doesn't talk much about dressing, as long as he is not seen by those officials in the palace, even he usually wears Hu clothes.

"You have seen it, Erchen plans to rebuild the house, this is too boring to live in, and it is a little uncomfortable." Looking back at the messy yard, Li Chengqian said with a bitter face.

"You're not cultivating, you're demolishing, half of Zongzheng Temple has been demolished by you." Li Xiaogong, who had already circled in Zongzheng Temple, walked over from afar.

"Uncle Hejian Wang, don't worry, can't I promise to pay you back a better one in two days." Li Chengqian was afraid that this Uncle Wang would fall into the well again, so he hurriedly blocked his next words.

The old man is angry enough, if this Uncle Wang is adding a few words to add fuel to the fire, then the days will really not be able to live.

"Two days? Tear it down like this, and you can fix it back in two days? Li Xiaogong said with a joke on his face.

"Three days, three days at most." Li Chengqian stretched out three fingers and said.

"Cheng, this is what you kid said. If you can really repair it in three days, the old man will intercede with you and ask your father to spare you this meal; If you can't fix it back, hehe, don't blame the old man for falling into the well. He looked at Li Chengqian again with a scrutinizing gaze for a while, and the unscrupulous old man Li Xiaogong said.

"King Hejian, your bet is really unwise, I'm afraid you will lose very badly." The eldest grandson Wuji took a turn in the yard, and finally stood on the edge of the half-alive sand and cement, and joked to Li Xiaogong.

The eldest grandson, the old fox, was notoriously cunning, and as soon as he said this, he attracted everyone's attention at that time.

"Mowgli, hide it and make it clear." Li Er's attention was also attracted by the eldest grandson Wuji, and he looked at the push of sand ash under his feet and said.

"Cheng Qian, let's talk about it, what are these things on the ground?" The eldest grandson Wuji winked at Li Chengqian and asked.

Returning a grateful look to the eldest grandson, Li Chengqian didn't care about the pile of live sand on the ground, but walked to the edge of a bunch of pockets, patted it on it and said: "Let me introduce to you uncles, the latest product of the Carboniferous Division, whether in military or civil, will be widely used in the construction artifact - cement." ”

"Don't fart, talk well." "Slap" The old man slapped Li Chengqian on the back of the head.

"Ugh." Retracting his head that was almost slapped into the cement, he glanced back at the old man resentfully, and after brewing for a long time, he found that he couldn't squeeze out a single tear.

"Cement and sand are mixed together in a certain proportion, and when mixed with water, the adhesion between the masonry can be increased, and when dried, it is no different from masonry. Moreover, cement is easy to use and has a wide range of uses, whether it is in civil buildings, military fortresses, or even bridges and paving roads. ”

Trying to recall the introduction of cement in later generations, Li Chengqian said slowly. The main reason is that Lao Li came too suddenly, so he was not prepared at all, and the preparation of the words was not very comprehensive.

"Uh, Uncle Wang......" Just when Li Chengqian was a little short of words and was about to take a breath to continue, Li Xiaogong had already reached the edge of the cement bag, and a big hand was inserted into the cement bag with a 'poof'.

"What's wrong?" With one hand in the cement bag, the unscrupulous old man Li Xiaogong raised his head and twisted his eyebrows and asked.

"No, it's okay, but Uncle Wang, your hand ...... Don't you panic if you don't burn? Taking two steps back, Li Chengqian asked in a tangled manner.

"Burn?" Li Xiaogong was a little confused, and then: "Donkey Day, what is this!" ”

Pulling his hand out of the bag violently, he patted it his body, and slapped the cement on it, and the unscrupulous old man finally felt that the cement was a little burning.

"Uncle Wang, this thing is similar to lime, it's very hand-burning." Take two more steps back and move away from the old man on the verge of rage.

"You bastard, you don't say it sooner." Li Xiaogong said angrily, wondering if he had collided with an immortal today, why he was so unlucky.

"You two don't make a fuss, prince, tell me about this cement." Hearing that there was a military purpose, Li Er immediately forgot the purpose of coming here, pulled Li Chengqian over, pointed to the cement and said.
