"Ironwood: Everyone is here to learn how to prepare for crossing, I have learned how to make salt, soap, glass, winemaking, papermaking, etc. 》

"Qin Yi: After passing through, remember everyone to work together, become bigger and stronger, and create brilliance!" [Tooth baring]. 》

"Tiantai Mountain: Good guy, it turns out that I am not the only one who thinks [look], and sure enough, I have seen too much [look], and I think that if I cross over, at least I can mix the wind and water. 》

Qin Dynasty.

Qin Shi Huang frowned when he saw this comment.

Why do the people of this later generation always want to cross? Isn't it good to live in your own time?

However, seeing the skills that later generations learned in order to travel through time, Qin Shi Huang became interested in soap and glass.

As for salt, papermaking, and winemaking, these three things that the Qin Dynasty originally had, Qin Shi Huang was no longer interested, and he wanted to know the role of these two things.

Why do people in later generations still remember these things after they have crossed over, and feel that after having them, they can work hard after crossing over?

Not only Qin Shi Huang was curious about these two things, but also the emperors and people of other dynasties were curious about these two things.

They wondered if these two things, like paper and salt, were essential to human life.

After they crossed over, how did they take advantage of the wind and water of these two things?

"Happy Day: Crossing Pre-Skills: 1. Strange Accidents; 2. The orphan suffers from a terminal illness, and the more painful the terminal illness, the better, which affects the passive real man BUFF you go to over there; 3. It is best to be a graduate student in archaeology, and not to fall behind in mathematics, physics and chemistry. 4. Go to the tourist area to buy antiques or divine objects, which affects whether you can turn on the system ......"

This...... Is that really the case?

After the dynasties learned about the concept of crossing, the people who wanted to cross saw the definition of crossing on the canopy, and they were deeply skeptical.

In their previous worlds, the concept had never been crossed.

It wasn't until these two words appeared on the canopy that they became more and more aware of the word traversal.

But why are these conditions needed? This made the people of all dynasties and generations very curious.

Even some patients, seeing these conditions on the canopy, they feel that they are lucky to have reached the preconditions of the traverser, in that case, can they also cross?

After the other people saw this comment, they learned a lot of skills in order to travel through the same as the people in later generations.

The emperors of various dynasties also deeply felt the novelty when they saw the conditions of crossing the canopy.

It's just that they also have a little doubt in their hearts, wondering if these conditions are true?

If it's true, why have they never encountered one?

So they gave an order to get more people to pay attention to whether there is a real traverser?

If there is, they hope that these traversers can help them learn the content on the canopy faster.

"Sending Carbon in the Snow: It is better to take out the three divine books of "Barefoot Doctor's Handbook", "Militia Military Training Manual", and "Friends of Military and Civilian Talents", I believe that after crossing over, if you take out these three books, you will be the king and dominate [呲tooth][呲tooth][呲tooth]. 》

Qin Dynasty.

Qin Shi Huang looked at the comments on the canopy, his brow furrowed even tighter.

The names of these three books are very straightforward about their role.

And these three books, as you can tell from the name, their role.

Is this book really as magical as it says in the canopy? Able to make the traverser king and dominate.

Not only Qin Shi Huang was so suspicious, but the emperors of other dynasties were also very suspicious.

In their opinion, books from ancient times to the present, except for a small number of books such as "The Art of War", which are helpful for attacking the world, what remains is more of a method of governing the world.

However, now the canopy of heaven actually says that these three books are divine books, which can allow a time-traveler to claim the throne in ancient times, which is really underestimating them!

Those ambitious careerists in the various war-torn eras, when they saw the three books mentioned on the canopy, they felt that they needed it very much.

If these three books are really as they say in the canopy, they can also go up and sit on the throne they think.

"Haha: [smiles] Anything can burn to more than a thousand degrees. 》

"No Taste: Add More Coal. 》

"The Freedom of the Wind: Is Coal Expensive or Not Expensive?" In which dynasty was the coal dug up? What if there is no coal? 》

Oh my God! : Charcoal is better. That's very simple, dig a hole and burn the wood, you can make it. The temperature is higher than coal. It is even possible to alchemy [than heart]. 》

Qin Dynasty.

Qin Shi Huang looked at the information on the canopy, and he was a little confused.

If you heard earlier, it takes more than 1,000 degrees to make cement, so he doesn't know what to burn to reach this temperature.

However, now the answer is given on the canopy, which is to use this kind of thing called coal, or to use charcoal, and also kindly gives the steps of how to burn charcoal.

Qin Shi Huang was very pleased with such a comment.

Not only Qin Shi Huang was delighted, but the children of the Mo family were even more like a treasure.

Just now they were worried about how to burn such a high temperature, and now the comments on the canopy gave them a solution.

Now that they had a solution, they hurried into action.

They used that kind of burned carbon, and as for that coal, they didn't know exactly what it was, so they had to give it up.

After two days, after the struggle of the children of the Mo family, the cement was finally fired.

But they didn't know how effective it was, so they learned from the canopy, found some water, sand and cement to mix, and smoothed it on the ground at random, waiting for the final experimental results.

After a while, the cement slowly dried.

The children of the Mo family first looked at the dry cement and found that the color was really like a stone on the canopy.

They struck it with the hammer again, and found that it was as hard as a stone, and the hammer landed on it, leaving only a white mark.

The children of the Mo family were very happy to see this result, and they felt that this was the cement mentioned on the canopy.

They hurriedly passed the good news to Qin Shi Huang, after all, Qin Shi Huang had been waiting for their answer.

Qin Shi Huang looked at the cement in his hand, and he was very happy.

Although he didn't know how much this kind of thing would cost, in his opinion, since it was so magical, even if it was too expensive, it was acceptable.

And Qin Shi Huang believed that with the artifact of cement, the speed of building the Great Wall would be greatly improved.

Song dynasty.

Shen Kuo was very happy when he saw the method on the canopy.

Coal is such a thing as in his "Dream Creek Writings".

But this kind of thing is not very popular.

Moreover, coal in the open air is even less rare in nature, and more of it is buried deep underground.

However, seeing that this kind of thing on the canopy can be used to burn cement, Shen Kuo feels that this kind of thing will be used by many people in the future, and it will also be mined in large quantities.
