Time flies, it has been nearly two months in the blink of an eye, and the end of the year is approaching.

During this time, Li Yuanjing stayed in Huangzhuang and rarely left here.

The biggest change in the Huangzhuang in the past two months is the addition of a blue-gray stone wall made of strange materials.

Li Yuanjing's guards have been expanded to six hundred, and although they are not yet full, it is more than enough to control this place from being invaded.

In addition, a thousand palace guards were transferred from the palace to station in the cement workshop, and the transformation of Yangli's loom failed after a month and a half of sinking, and finally found a breakthrough in the last half a month, and soon a new loom could be developed.

In addition, Li Yuanjing was shy in his pocket, and he made a sum of money from several two hundred and five, which was called an investment.

But several people jointly contributed 20,000 yuan, but only got 40% of the shares, and the remaining 60% belonged to Li Yuanjing.

A large part of this money was used to purchase cotton linen and raw materials for weaving.

Li Shimin had almost forgotten about this matter, and received a notice from Li Yuanjing three days ago that he could come for acceptance.

However, Li Shimin did not come immediately, but waited until Hugh Muri to bring a few henchmen and ministers, most of whom were military generals.

As for the iron that Li Yuanjing requested, Li Shimin did not give him 10,000 catties, only 2,000 catties, and the iron of the imperial court was not rich enough to play at will.

"That's what you came up with?" Looking at the building in front of him, although he felt very magnificent, Li Shimin couldn't help but feel angry.

"Brother Chen just doesn't want to waste it, anyway, it's just an experiment, you can't build a section of the city wall, right? What will my palace do with the walls? Li Yuanjing didn't care at all.

I gave 2,000 pounds of iron, what kind of bicycle do you want?

We are considering this in line with the principle of not wasting it, which is also to facilitate your experiments, or this king would not have built this gate.

That's right, Li Yuanjing took two thousand catties of iron and built a new gate of King Zhao's Mansion, which is also the reason why Li Shimin was angry.

"Is this thing really indestructible?" Cheng Zhijie circled around suspiciously, and then reached out and touched it, it did feel different, but if it was said to be indestructible, he still didn't believe it.

"The water here was put in ten days ago, as you few little rabbits can testify, and they put it in themselves." Li Yuanjing pointed to an area specially circled in the corner of the wall on the ground, and dug a pit, in which a certain amount of water was maintained, so that the roots of the wall could be soaked in water all the time.

Cheng Zhijie's suspicion also represents the suspicion of most people, but Li Yuanjing just likes this kind of suspicion, and only when there is doubt can he be slapped in the face.

"Chen Miao, take the hammer!" Li Yuanjing shouted to Chen Miao on the side.

Chen Miao is Chen Ershui, this name is still given by Li Yuanjing, and Du Ruhui, the head of the household department, personally did it, and it is also a lot of face to brag to his grandchildren in the future.

Look at your grandfather and me, the name is from King Zhao, and the household registration is personally run by the Hubu Shangshu, and even the emperor Lao Tzu nodded in approval, so he asked you are awesome?

Li Yuanjing took the hammer, handed it directly to Cheng Zhijie, and said with a big grin: "Come, the hammer is given to you, the location is as you choose, give you a day to smash it down, and the king will eat this gate!" If you can't smash it, you will lose the king's money for repairing the door! ”

"Hehe, that's what you said!" Cheng Zhijie looked at Li Yuanjing with a cheap smile.

He raised his hands and spat on them, rubbed them hard, and then picked up the sledgehammer and slammed it towards the door.

If you want to say that it is stronger than the ordinary city wall, Cheng Zhijie will not object to this, it feels quite strong, but if you say that it can't collapse in a day, you can't help but look down on me Cheng Zhijie, right?

This gate is only about two steps wide, or a day, half a day is guaranteed to collapse for you.

As an experienced veteran general, Cheng Zhijie still had to nod his face, and did not directly carry a sledgehammer to smash the wooden door, because that door was obviously not within the scope of the assessment.

Cheng Zhijie directly chose the corner position to start, it is the most vulnerable place, and he will not choose there when attacking the city, but it is definitely the easiest place to be smashed when he is attacked.

Looking at Cheng Zhijie's excited appearance, Li Shimin looked at Li Chengqian thoughtfully and asked, "This door really can't be broken in a day?" ”

"If it's bad, it's sure to be bad, but it's hard to smash it, and it's the sledgehammer that can bring the most damage, and the sword or something will leave a mark at most, and the palace guards have broken more than ten weapons just for testing." Li Chengqian glanced left and right, and found that the other ministers were eavesdropping with their ears pricked up, so he couldn't help but take a step closer, and said in a lower voice:

"Father, those iron were made into steel bars by Uncle Wang, staggered and arranged inside, and then put into the mud mixed with cement, sand, and stones, and ordered people to continue to pour solid, after a month of air drying to completely dry, the bottom has been soaked in water for twelve days, it is still very hard, Erchen will come to check every day, even if Su Guogong smashes the surface, he will be helpless when he encounters the steel bars inside."

Li Shimin was slightly stunned, Li Yuanjing proposed that it was only two months, and it took a month to dry it, and the materials had to be prepared during the period, so ......

"How long did it take?"

"Seven days, mainly waiting for the blacksmith to beat the iron into steel bars, if there are ready-made steel bars, three days is enough, Uncle Wang said that it is not strong, it depends on whether it is smashed and strong when it is built, half a month in winter is enough, but there is no harm in a long time, it will be ten days at most in summer, and the effect will be better than now." Li Chengqian has changed his opinion of Li Yuanjing.

The experience of the past two months has made him feel that this world is really amazing, and there are so many interesting things.

And Li Yuanjing didn't criticize himself every day as he imagined, here, Li Chengqian didn't need to read, just play casually with different craftsmen every day, and if he was interested, he could also experience it himself, which was fun, if it weren't for the greater attraction of the throne to him, Li Chengqian wouldn't even want to go back to Chang'an.

On the other side, Cheng Zhijie had already smashed dozens of times with a sledgehammer, and a large piece of the corner of the wall was indeed smashed, but his hands were as heavy as being poured lead, and the shock was painful.

'Bang ......'

With another hammer, a piece of concrete shattered into small pieces and fell to the ground, and Cheng Zhijie finally saw the true face inside.

Moment......

"You're a fool! The old man stopped playing...... "Seeing the internal structure clearly, Cheng Zhijie threw the hammer on the ground in a huff, he was already desperate.

I've smashed it hundreds of times, right? As a result, only so many points were smashed, and there were still steel bars like spider webs inside, and it was so hard to smash a concrete, Cheng Zhijie was very skeptical that he could break the first steel bar before dark.

Li Yuanjing looked at Cheng Zhijie with a smile: "Giving up is equivalent to failure, losing the money of the king to repair the door, 1,000 yuan, if you don't give it, you will deduct 2,000 yuan from the shares, half of which is interest!" ”

"Yuanjing!" Li Shimin had to shout with a straight face, Cheng Zhijie can be regarded as the captain of the acceptance team this time, right? How can you make him lose money?
