"I'll go, isn't it just fuel! You don't know, this king knows, there is a natural black stone in North Hengzhou (now Datong, Shanxi), that can be used as fuel, as a fuel is a first-class good thing, and not only in North Hengzhou, there are also many in Taiyuan, by the way, this king wants Zhang Gao to buy more such black stone mountains, and you wait a minute" said, Li Chengqian, who thought of something, found a pen and paper on the spot, where to write and draw.

Soon a modern honeycomb coal stove appeared on the paper, as well as supporting honeycomb coal, and what was even more infuriating was that Li Chengqian also drew the boiler, and after Li Chengqian finished drawing, he handed the drawings to Mo Cheng: "Mo Lao, take a look, can you make this old man?" ”

"This is very simple, you don't need to be old, just find a blacksmith, but Your Highness, what's the use of this thing" Mo Cheng took the drawings and looked at them, and said to Li Chengqian.

"If you can do it, that's okay, the one above is for heating, you can also boil water for cooking, put in honeycomb coal made of black stone, just three pieces can be used for at least 3 hours, and the back is a cooking utensil, this Mo Lao doesn't have to worry about it, this king asks people to get it, this king is very curious now, what other technology does the Mo family have, can you always talk to this king" After introducing the honeycomb coal stove and fire boiler, Li Chengqian was really looking forward to the Mo family's technology.

"This, there are a lot, I don't know what His Highness is asking" Mo Cheng looked at Li Chengqian after speaking.

Hearing this, Li Chengqian was about to go crazy, did he think this was the first time, in the end, is my brother crossing the crowd, or is your Mo family's disciple crossing the crowd, there are still a lot?

However, with Mo Cheng's introduction, Li Chengqian knew that there were really a lot, such as the more useful high-temperature forging technology, the waterwheel mill powered by water flow, and the cement that passed through the alleys, and the Mo family also got it, in addition to these, there are also the Mo family's most proud siege mechanism, crossbow arrows and so on.

After listening to Mo Cheng's introduction, Li Chengqian really didn't know what to say, this Mo family has so many advanced technologies, some of which are still hundreds of thousands of years ahead of the world, just because of the suppression of Confucianism, and their self-style, they have not been promoted, so that these technologies that should have changed the world slowly disappeared in the long river of history, until hundreds of years later, they were re-figured, this is the sadness and helplessness of this era, but now it will not be, with him, these technologies will wait until they should have a little light.

"Mo Lao, look, these are all good things, can you ......?"

"Your Highness is polite, if Your Highness sees it, these techniques can serve Your Highness, and since my Mo family is loyal to Your Highness, then these techniques are Your Highness" Looking at Li Chengqian's excited look, before he could finish speaking, Mo Chengcheng, who had already understood what was going on, spoke.

"That's really good, you can rest assured, these techniques are all the children of the Mo family, this king will never treat them badly, whether it is fame or fortune, it should be given, this king has a lot" But as soon as he finished speaking, Li Chengqian regretted it, this money is nothing, but this name, now he wants to give, he really doesn't know how to give, if he wants to give it, he has to let his father know, but knowing that it is really not good for him.

"Your Highness doesn't have to be entangled, this fame or fortune or something, the old and the old disciples don't care, so Your Highness doesn't have to be like this" Mo Cheng saw Li Chengqian's entanglement, and immediately comforted Li Chengqian.

"That's okay, let this go in advance, you always hurry up and bring your Mo family children to Chang'an, you don't need to work in the workshop, you are directly looking for a place, just study what you talked about just now, make a process out, so that ordinary workers can produce on a large scale, this is what you have to do in the future, how to get it, how to reduce costs, simplify the process, these kings don't know much, just look at it, this king will let Zhang Gao fully cooperate with your old man, but one thing is that you can't pass it on privately" After speaking, Li Chengqian was excited, I thought I was looking for some craftsmen, but I didn't expect it to be a group of scientists.

"Your Highness, this is not very good" Mo Cheng looked at Li Chengqian with some apprehension.

"What's wrong with this, you're always worried about spending too much money, it's completely unnecessary, as long as you can make some good weapons, you can give my Tang soldiers more hope of surviving on the battlefield, how much money the king spends is also worth it, I'm saying that you don't make money for this king at all, just say that Liuli, as long as the quality of your apprentice improves, then I'm afraid that this king won't make money, it doesn't exist, so you can take your Mo family disciples to get it with peace of mind" Li Chengqian, who knew what Mo Cheng was worried about, explained to him.

"Since Your Highness, you have said so, then the old man will definitely live up to His Highness's entrustment" Hearing Li Chengqian's words, Mo Cheng thought about it and said to him.

After that, Li Chengqian discussed with Mo Cheng and others, although Li Chengqian didn't understand a lot of the specific matters of the newly established Royal Academy of Sciences, but after all, later generations saw a lot, and he told Mo Cheng about some of the management and some things that sounded like production, whether it was right or wrong.

Just such a dare to speak, a dare to listen and dare to do, and soon some details of the Royal Academy of Sciences were recorded by the ink ducks on the side in this child's play-like dialogue, and it also became the code of conduct of the Royal Academy of Sciences in the future.

Until Zhang Gao came back, Li Chengqian handed over the purchase of coal mountains and the establishment of various workshops to him, Li Chengqian once again became the shopkeeper, and after having a rich meal with Mo Cheng and others, his family directly took Mo Li back to the barracks.

In the days that followed, Mo Chengcheng, with the cooperation of Zhang Gao, bought a large amount of land not far from the workshop, directly built the Royal Academy of Sciences, the cradle of Datang's advanced technology in the future, and asked people to bring a letter back to Qiantang and let all the children of the Mo family come over.

Compared with the smooth sailing of the Mo family, Zhang Gao, who had been busy with various things, was forced to fall ill.

Regarding Zhang Gao's illness, Li Chengqian found that there were still too few people around him, although he was also cultivating by himself, but the time was still too short, there was no way, he could only beg his wife, give him a few old people, and let them help Zhang Gao and share everything.

And the eldest grandson, Wuji, who has always wanted people to go in and see what his son is doing, is happy to help with this.

And because Li Chengqian was too confident, thinking that he had cleaned up the ground rats in the East Palace once before, thinking that these people wouldn't say anything, he didn't specifically order them.

But he forgot that it was his wife standing behind these people, and it was such a little omission that made him severely beaten in the future.
