After everyone dispersed, Liu Che waved his hand again, retreated from the maid eunuchs in the palace, and left the royal road to serve.

"Qing has been familiar with the workshops and craftsmen of Sixian Yuan these days, so I think I should have some opinions, let's talk about it...... listen to it," Liu Che asked softly.

Yang Yi was a little restrained after all, and he couldn't let go of it, so he lowered his head and said a few opinions to Liu Che.

Liu Che asked Wang Dao to write down all these opinions, and instructed: "Take these recorded opinions to Zhang Tang to see, and if there are any changes, they will be encouraged......

"No!" Wang Dao nodded.

When Yang Yi heard this, he was also quite moved in his heart, and he only felt that the style of this prince was indeed a little different from the Liu family legend in the door.

At the very least, it's very respectful.

The relationship between these days also shows that the prince has no prejudice against the Mo family.

He even respects the beliefs and habits of the Mohists.

For example, he was allowed to walk barefoot in the palace.

In this way, perhaps, the teachers and brothers in their own sect can also try to assist this one.

It's just that......

Yang Yi lowered his head and thought for a while, and finally asked: "Qi Qi family, the family may not know, my Mo family has a system, and those who are masters need to implement and carry forward my Mo family thoughts and concepts......

"Lonely Knowledge!" He was only halfway through his words when he was interrupted by Liu Che waving his hand, only to hear Liu Che say: "A hundred flowers bloom and a hundred schools of thought contend, and Gu has always been quite recommended...... Just ......"

Liu Che stood up and looked at him, and said solemnly: "Differences in ideas cannot be brought to work. The academic returns to the academic, and the political zhì returns to the government, and there are those who have transgressed. Loneliness is never indulgent, do you understand? ”

When Yang Yi heard this, he said respectfully: "The minister knows!" ”

As long as the prince can maintain such an attitude, it will be the greatest benefit to the Mo family.

If you talk about competition, go head-to-head, whether it is literary debate or martial theory. The Mo family has never been afraid of the other princes.

Liu Che walked up to Yang Yi, looked at him, and pondered for a moment. Finally said: "Qing also learned about the work of Baigong in Sixian Yuan, and next, there are a few tasks to be handed over to Qing!" ”

"Please command the family, and the ministers will bow to the best. Die for your family! Yang Yi bowed his head and said solemnly.

"First things first. Qing for the lonely to study this thing, to see what kind of ratio, in order to meet the requirements of the lonely, regardless of the method, time, the sooner the better! Liu Che said and handed a blank piece of paper full of words to Yang Yi.

Yang Yi took it and looked at it, and was stunned for a moment.

I saw that the beginning of the paper wrote: If you want to unite things, you should combine them with water. Ten days are self-drying, solid as rocks. The name is cement, and the ingredients are said: a number of furnace ash or enamel fragments are ground into powder, a number of quicklime, and a number of gypsum.

This is a kind of cement products that were put on the horse by the soil method when the Celestial Empire was buzzing in later generations.

It is the easiest version of cement to prepare and manufacture in human history.

There may be many limitations in terms of quality and use.

But, this soil cement is still cement!

In the era before Liu Che crossed over, when he was very young, he had seen his elders grind some limestone and clay into noodles, and then add slag or something after calcination.

It can be said that it highlights a simple and crude, which can be regarded as a way for working people to use their own wisdom to invent and create zào when material is extremely scarce.

It's just that later, the society slowly became richer, and cement was no longer luxurious, so after Liu Che went to school, this kind of soil cement has disappeared.

Therefore, Liu Che himself does not remember the formula and manufacturing process of this soil cement.

But it doesn't matter.

In his previous life, Yang Yi relied on the little clues given by Liu Che, and it only took one year to prepare soil cement in the Western Han Dynasty, so Liu Che already knew the specific formula.

It's just that the proportions or something forgot about jì.

"With a formula in this life, even if Yang Yi is not as powerful as in his previous life, he should be able to get earth cement in a short time, right?" Liu Che thought to himself.

This soil cement is certainly inferior to modern industrial cement.

But for Liu Che's next Daxing water conservancy, it can be described as an artifact.

The only downside may be that the cement consumes a lot of energy and is very harmful to the environment and workers.

It's just, to develop industry, where is there no pollution?

Yang Yi pondered for a while, and thought: Since the prince has given the formula, I will give it a try......

So he nodded and said, "Please continue to command!" ”

In Yang Yi's view, this matter is just a job to practice, and the amount is not large, and it only needs to be supervised and supervised.

It is far from the kind of device that Yang Yi thought in his heart to create a world-changing instrument by relying on his hands.

After all, Yang Yi is still young and has limited knowledge, so it is impossible for him to estimate what kind of changes cement will make to the world.

Liu Che remembered very well that in his previous life, Yang Yi's mouth couldn't close after seeing the power of the cement on the soil law.

Therefore, he was too lazy to say, and continued: "Second, Gu Zeng said to Qing before that if he wants to create a thing, take water from the rivers and irrigate the fields, Qing can start to study this matter!" ”

In fact, this waterwheel is common to the hydraulic forging press in many principles, and basically the waterwheel can be used to make the basic hydraulic forging facilities.

Liu Che had seen some hydraulic rice machines before crossing, so he knew that the principle of the two was the same, and the only difficulty was the problem of output power.

If you want to forge plate armor, the output power of the hydraulic forging press must at least reach the point where it can swing dozens of catties of hammers day and night.

And this research and development work, within a few years, Liu Che still can't see the light of day for the time being.

It is better to first build a waterwheel and a water-powered rice machine, use these relatively simple basic technologies to accumulate experience and train craftsmen, and then promote a hydraulic forging press with a larger output power, which is more appropriate, and can also benefit the country and the people.

"Third, Lone plans to classify and name the world's ores, Qing can relay this news to the sages of Momen, if you are interested, you can come to Chang'an to participate in this matter!" Liu Che said shallowly.

It was kind of a decoy he threw out.

It has been used to attract some Mohist technology nerds, and at the same time, it can be regarded as a foreshadowing for the compilation of the future Western Han Dynasty version of the encyclopedia.

Liu Che planned to use the power of the state to compile an encyclopedia covering geography, biology, nature, and science in the future, as a basic book for local officials with more than 800 stone and government officials with more than 1,000 stones.

Lest there be someone who reads books and becomes a nerd, who can't even figure out basic common sense and makes a lot of jokes.

At the same time, Liu Che knows better that the advent of an encyclopedia like this will greatly expand people's horizons, so that at least the elite will not be too stupid.

For a dynasty, ensuring that the majority of its elite bureaucratic class is not stupid is the most important matter in the life and death of the dynasty.

And at this moment, for Liu Che, for the time being, this matter is just a cover to avoid too much interference from public opinion.

Regarding the introduction of the Mo family, Liu Che feels that it is better to be careful and slowly test the reaction of public opinion! (To be continued......)
