In fact, in fact, I first went to visit Lu Deming, Li Gang, Kong Yingda, Yu Zhining, Li Baiyao, Du Zhenglun, Qin Shubao and other teachers, and gave gifts, thanking the teacher for his education.

Then there are some young people of the same age, such as Li Yuanchang, Changsun Chong, Wei Shuyu, Du He, Fang Jun, Cheng Chuliang, Chai Lingwu, Wei Chi Baolin, Qin Huaiyu and more than a dozen people came to visit him, negotiate investment intentions, discuss whose girl is beautiful, take a lot of good things from him, and say in his own name: like-minded, like-minded.

Immediately afterwards, some young officials, such as Ma Zhou, Sun Fujia, Shangguanyi, Yan Liben, and more than a dozen of them, including Guozijian, came to visit the meeting, talk about the past and the present, recite poems, discuss policies, and discuss the disadvantages of the times. Each person took a lot of things with them. He is known as a faithful believer and a die-hard fan.

As for the other civil and military ministers above the fourth grade, none of them went to visit, let alone visited, so they really couldn't do it. He has long understood in the past few years that in novels, films and television, the protagonist can do anything, dare to do anything, that's nonsense, no matter which prince you have, without Li Shimin's permission, it is impossible for you to go to the East Market in Weifu, let alone other things.

After the change of Xuanwumen, Li Yuan became acquainted with each other and quickly abdicated and gave way to the East Palace. If Li Yuan doesn't abdicate, Li Shimin will kill this old man. Li Shimin is a good emperor? Li Yuan is willing to give up power and abdicate willingly? Li Jiancheng must not be able to become an emperor? Anyway, Li Chengqian doesn't think that Li Shimin is a good person, after all, he has seen this Lao Tzu's insidious and vicious methods. Although this father is still very good to himself, it is also because he is the eldest son, and he knows how to be polite, knows how to advance and retreat, and abides by the rules.

I finally stopped, it was already the seventh day of the new year, and I thought I could finally rest for a while. Wang Shouquan personally ran over.

"Why don't you let your father-in-law run around and send a guard over?" Li Chengqian asked while handing over a pot of tea with a smile.

"What the sage ordered, the old slave didn't dare to change hands to others, and now the sage is waiting in the Hongwen Pavilion, so you can go and meet alone." Wang Shouquan took the tea, and then said in a low voice, "Your Highness rewarded it, and the old slave accepted it with shame." In addition, if you have any other good things, Your Highness, you may wish to bring them, I believe that the saint will be even happier. ”

In the inner hall of the Hongwen Pavilion, Li Chengqian, who looked flattered, sat on the side of the tea table and looked down at Li Shimin, who had been silent, feeling helpless. You called me here and just sat there? Pretending to be deep? Didn't you have enough at the court? Anyway, I want to say something.

Li Shimin was holding a cup of tea at this time, squinting and leaning on the wide general's chair. A look of satisfaction and intoxication. I couldn't help but think about it, it turns out that tea can still be drunk like this. No, I'm so tasteful, I should be tasting tea, and it's not right, it's so cheesy to call tea, another way to call it tea, well-it's better to call it tea tasting in the future. If Li Chengqian knew that he had been thinking about this, he would definitely despise him for a long time.

It took a long time for Li Shimin to open his eyes and say with a smile: "Gao Ming, you have recently made a lot of fresh things, and the thing that Grandpa feels most happy about is sugar tea." Your industry has added a lot to my Datang, and I am very grateful. However, at the moment, it seems that most of them are strange and obscene items, but there are few things that are useful for the national society. Remember that you had a lot of ideas before, and you don't know how to go? In these aspects, Grandpa has also helped you a lot, what can Grandpa see? ”

This is a naked open mouth, Li Chengqian thought in his heart, how many people did you send to be undercover agents to find out the news in my industry? Now it's just the right time to take advantage of the trend. Thinking of this, he opened his mouth and replied: "Actually, I haven't made anything good, Grandpa knows, I don't have money, and many things can't go on, but although I am short of money, I still got some good things for Grandpa, Grandpa, please see." ”

After that, he took out a stack of papers, took out a few, and handed them to Li Shimin. Li Shimin took the paper in his hand, but his eyes were staring at the paper that his son put into his arms again, and he couldn't help but swallow. And also?

Movable type printing? Improve the efficiency and quantity of printed books, reduce costs, and make books accessible to the poor? Concrete? Roads can be built and foundations can be made. Horseshoe? Improve the combat capability and service life of war horses. Concrete (concrete)? Better than bluestone for building cities, roads, and building materials. Li Shimin looked at the explanation on the paper in his hand, and his heart jumped wildly involuntarily.

"My son has brought the real thing over today, and now they are all outside the door, so let them move in, grandpa, please take a look." Li Chengqian instructed the guards and brought things in. In addition to the first printing machine is easier to identify, I think I can still imagine the outline, and the rest is basically not understood.

"Horseshoe, where?" Li Shimin's first concern is this, and cavalry is the most important thing for him. Looking at the ring of cast iron and a few nails handed to him by the guards in confusion, what is this?

"It has been experimented on the royal estate, and the horses with the horseshoe nailed to the horseshoe are generally longer running than those without nails, and running in the gravel Gobi land is not easy to wear, fall and slip. The horse's hoof wear is reduced, and the life of the horse is extended. Li Chengqian said while gesturing with a horseshoe.

Li Shimin made a comparison and suddenly understood that this is an excellent idea, in the future, the combat power of the war horse will be increased by at least two percent. Isn't it just a piece of iron, a few nails? So easy to solve the problem that has been a headache before? It's so simple, why can't others think of it?

"Good stuff, a small thing, a big problem. Gaoming, what is concrete? Li Shimin laughed. Li Chengqian pointed to a stone slab that was two feet long, more than a foot wide, and five inches thick, "This is concrete, in fact, this thing is made of cement sand and gravel mixed with water in a certain proportion, I call it: concrete." Grandpa can find a powerful samurai to try it with a hammer. ”

The two strong men smashed for a while, panting tiredly. Looking at the concrete block that did not move except for a few white marks on the surface, Li Chengqian thought to himself, he didn't know how to find a sledgehammer, without a sledgehammer, it was impossible to move with this small hammer alone. Li Shimin gasped. It's harder than bluestone.

"Grandpa, imagine that if you use this thing to build roads, you will no longer be afraid of damage, and you will not be afraid of mud on rainy days, even if the speed of marching and transporting food will increase. If you use this thing to build a city wall, who can break it? If you build a dam with this material, you will not be afraid of flooding, and if you build an aqueduct, you will prevent the water from leaking. And if you use this thing to repair the granary? Grandpa think about it. I don't know if Grandpa likes these things? ”

"Gao Ming, what you said is too important to Jiangshan Sheji, you have a heart. Grandpa will consider the use of these things as soon as possible, what are your requirements now, or is there anything Grandpa can help with? Li Shimin couldn't suppress the joy in his heart.
