The stick did not fall on Li Hao in the end, because at the most critical moment, the mother Hongfu, who was going shopping, came back. A light-piao-piao sentence made the old man give up his plan to chase Li Hao to the ends of the world: "Husband, no matter what mistake Dejian made, it is my responsibility, so if you want to hit you, just hit me."

Li Jing had no choice but to put down the stick in his hand: "Madam, you don't know, this gangster, this gangster actually spoke wildly in front of His Majesty, saying that all the military exercises in the past were plays. If you want to know the true combat power of the army, you must fight with real swords and guns."

Hongfu looked at Li Hao with a cute face and said, "Husband, Dejian is right. I have seen me in the past military exercises. A group of people fought for a long time, but in the end they didn't even get hurt. What's the point?"

Li Jing: “…”

He paused, shouted with a hurry and a white face, "But do you know that Madam, because of his words, he would build a city wall that is two meters high, five hundred steps wide and three meters thick within a month."

"What?" Hongfu's face changed: "This, how is this possible? Isn't this bullying?"

Hongfu is not a woman who doesn’t know anything. She knows very well that even in normal seasons, it will take half a year to build such a city wall. Moreover, it is spring plowing now and it is impossible to recruit people. It is no different to dream to build such a city wall within one month.

Li Jing stared at Li Hao angrily, snorted coldly and said, "This is not bullying people, but the jokes that the old guys plan to read me. But in the final analysis, all this is caused by this rebellious son's misunderstanding. Madam, do you think this rebellious son should be beaten?"

Hongfu was in a dilemma and said he shouldn't fight. Li Hao caused a lot of trouble. If Li Jing could not build the city wall within one month, it would be embarrassing. If he delayed the competition for the entire army, he would be suspected of dereliction of duty. It could be said that he should fight. Seeing his son's pitiful appearance, he felt a little embarrassed.

While he was thinking about asking for help, Li Hao said, "Dad, mother, isn't it just a city wall? This is nothing. As long as the court provides materials and wages, the child will ensure that he completes the task within one month."

Li Jing was furious: "Bastard, what do you do? Don't tell me that you want to recruit a large number of people. Now it is the busy farming season. If you dare to recruit people, you will be criticized by thousands of people immediately. My Li family will also leave a stigma for eternity."

Li Hao hid behind his mother Hongfu: "How is that possible, Dad, your son is very outstanding. Not to mention just a wall, even a whole city, it's not a problem."

Li Jing was so angry, but Hongfu was blocking the middle, and he had no choice but to deal with Li Hao.

There is no trick, at most, you can use wood to build a shelf and fool it in a fake way. Anyway, when discussing during the day, the old lights have no requirements for the solidity of the city wall.

The old man left and my mother left, and Li Hao stood at the door of the yard with his chin rubbed his chin alone.

Why don’t everyone believe me? Isn’t it just a city wall? I can really build it in one month.

"Young Master." The housekeeper Chen came up and said worriedly: "Young Master, you really did something wrong this time."

Li Hao smiled and suddenly asked back: "Old Chen, do you believe your young master?"

Old Chen was a little embarrassed: "Young Master, I really can't build a city wall in a month. This is a big project."

"The young master only asked you whether you believe it or not, and didn't ask if you could."

Old Chen hesitated for a while, and finally shook his head: "Young Master, it's not that I don't believe it, it's really..."

"Okay, OK, stop talking." Li Hao knew that Old Chen would not be able to afford a city wall for a month, so he waved his hand to interrupt him and said, "Let's do it, go outside and find out where there are lime kilns to sell. If so, buy more. It will be of great use to the young master."

"Ah?" Old Chen raised his head in surprise: "Young Master, what did you buy a lime kiln?"

"Stop talking nonsense. If you ask you to buy it, go buy it. If you don't have money, go to the account and give it two days. If you can't do it well, don't come back."

After sending Lao Chen away, Li Hao turned around and returned to his yard.

The essential raw materials for limestone, clay, gypsum, and firing cement are only proportions.

After writing down the required materials, Li Hao began to formulate a combat plan.

Yes, it is to formulate a combat plan, how to attack, how to defend, how to attack, and how to attack, all kinds of plans must be included.

As for the construction of the city wall... the cement was not burned out and any other city wall was built.

In the next two days, the old man was so busy that the dragon was not in sight. He probably was busy repairing the city wall.

Li Hao can't get involved in this kind of thing. Anyway, the old man doesn't believe it after some things are said. It's better to speak with facts in a few days.

Old Chen did not disappoint Li Hao. The day after he explained, he handled the lime kiln. Li Hao personally supervised it. After two days, after continuous experiments by ten kilns, the first batch of cement was freshly released in the eyes of everyone.

Staring at the dark gray powder piled together, Old Chen asked with uncertainty: "Young Master, is this what you are talking about cement?"

"Yes, this is cement." Li Hao nodded confidently: "Someone let someone pretend, and then buy some stones, sand, etc. The young master will let you see what concrete is."

"What a mess?" Old Chen was confused when he listened to the new noun.

"Concrete." Li Hao emphasized for a moment, then waved his hand: "Oh, you'll know how powerful this thing is in a few days. Now go do your business first."

"Oh." Old Chen turned around and ordered someone to do something.

Li Hao brought people to his house with a truck full of cement. Before leaving, he told people to continue boiling cement and not to stop.

...

...

Three days later, when Li Jing came back, he found that Li Hao was actually at home. Judging from the situation, it seemed that he was waiting for him.

"Is there anything wrong?" Li Jing asked lightly after glanced at the son who was coming to meet him.

The matter of repairing the city wall is irreversible. Let's give up. Li Jing has already accepted his fate at this time and has not scolded Li Hao again.

Li Hao didn't care about the old man's cold words, so he got up and went outside the flower hall, pointing to a gray stone slab: "Dad, can you recognize this thing?"

"What is this?" Li Jing frowned. The conditioned reflex made him feel that Li Hao was going to do something new.

"This is called a concrete prefabricated slab." Li Hao said, and handed Li Jing a sledgehammer.

Li Jing didn't take the sledgehammer and asked, "What are you going to do?"

"It's nothing, I just want you to try whether this thing is solid." Li Hao handed the hammer back to the iron pillar who was staying aside, looked at the gray stone slab affectionately and said: "This thing is as solid as iron and stone, and it is simple to make. Just mix the cement, sand and stones together and mix them evenly and then dry them."

Li Jing seemed to understand something vaguely. Just as he was about to speak, he saw that Tiezhu had already swung the iron hammer and smashed it hard at the prefabricated board on the ground.

With a loud "clang", under Li Jing's gaze, there was a white dot on the prefabricated board.

Well? No shattering? No cracking?

Li Jing's expression suddenly became solemn, and he seemed to realize something vaguely. He pointed to the prefabricated board and said to Li Hao: "You just said... is this thing made?"

Li Hao nodded and said with a smile: "Yes, this thing is very simple to make. Make a wooden box and pour the concrete slurry in. Open it after three days. This thing is this thing."

After saying that, Li Hao was afraid that the old man would not understand, so he explained: "Of course, this thing can also be used to build the city wall. As long as the box is made larger, it will only take three or five days to reach its current hardness."

"Be serious?" Li Jing suddenly felt energetic when he heard this. His back was no longer hunched, his eyes were no longer dazzled, and he looked at Li Hao and asked.

Li Hao said aggrievedly: "Dad, when did you deceive you? I said that it would be fine to build the city wall in January because there is concrete, but you insisted on doing it alone."

"Hmph, since there is this thing, why not take it out earlier? Red mouth and white teeth want to make your father believe that you think everyone is so stupid as Changsun Chong."

Hey? Why did you get to Changsun Chong?

Wait, it seems that I haven't been to Ling Mansion for several days, and I don't know how Changsun Chong was doing and whether he regretted it.

Thinking of Changsun Chong, Li Hao realized that he had to go back to Ling Mansion to check out. Even if he didn't want to be Changsun Chong, he would make arrangements for the entire army competition.

"Dad, I have told Lao Chen how to prepare this concrete. If you have anything to do, just ask him. I have to go back and prepare for the competition."

Regardless of whether concrete really works, at least it has an extra solution. Li Jing was in a good mood and waved his hand to his son: "Well, go, go, then, do not disappoint your father."

In the following time, Chang'an City was calm on the surface, but in private there was a turbulent tide.

Countless people were waiting to see Li Jing’s joke. It would be nice to lay out the foundation in one month. Build a city wall that is five hundred steps long, two zhang high and three zhang thick, and build a few bars.

But who can blame this? Who makes the Li Jing family's baby so worry-free?

You are so outstanding that others can live. You are good at medical treatment, good at writing poetry, and good at training troops. Yes, you can also cook.

I really don't know what that kid doesn't know.

Everyone was waiting for the envy, jealous and hated. They only waited for a month before the city was built, or Li Jing made a fake one to deal with it and then laughed at him.

In this way, April was unknowingly, and the acceptance time finally came. Li Er brought a group of court officials to the martial arts competition of Longshouyuan, the Longshouyuan, the north of the city.

Along the way, I saw a five hundred-step-long city wall lying horizontally like a giant dragon, with stalking on it, and flags like clouds.

"Oh, it really looks like that." Hou Junji looked at the "city wall" of the giant dragon plate from afar and sighed.

An old man immediately took over the conversation: "I just don't know if it's a silver-like wax gun tip, so don't be attracted by it."
