"Grand Commander, is it enough to stir up to this?" Wang Rucheng, who was in charge of firing glass, asked Yang Wenli not very confidently.

"It's not enough, the liquid glass has to be stirred until it is as thin as water, and there is no bubble before it can be baked, even if there is a little bubble, the glass cast is waste, so I would rather stir it more."

Yang Wenli explained to him that the ancients have always had the idea of moderation, and they only do ninety-nine things to do, and if they do not do it to the fullest, this is fatal in scientific research and often means failure.

"Ru Cheng, in scientific research, there are no uncertain factors such as maybe, should, almost, etc., but to achieve the extreme, because the nature of materials is often a little difference is the gap between heaven and earth." Yang Wenli did not forget to teach Wang Ru to become a Taoist.

"Thank you, Commander, my subordinates have been taught." Wang Rucheng hurriedly thanked.

Because it has been fired before, there is no difficulty in firing glass, and the amount is not large, only some small round, oval, and rectangular glass are fired, and it is only a crucible of liquid glass, and most of the time is completed.

In the grinding stage, Yang Wenli did not forget to tell Wang Rucheng: "Glass grinding, five processes, one can not be missing, the glass must be polished to the extreme flatness, squinting at it, it must also be horizontal on one side, without a trace of wave lines, which is a very important key to the glass mirror." ”

As he spoke, Yang Wenli handed him a piece of glass and said, "At a glance, the glass seems to be very smooth and flat, but if you try to look at it obliquely, you will see ripples like the surface of the water." ”

Wang Rucheng did as he said, and he saw that the glass that was originally very flat was not smooth at all, and he sighed in surprise: "Sure enough, Grand Commander, why is this?" ”

"This is the refraction of light, optics is a very advanced science, I have not studied it deeply, I don't know much, but there are scholars in the West who specialize in this science. The gap between our China and the West's science and technology is very big, because our Chinese scholars have gone to read the books of Confucius and Mencius, and they hate these strange and strange things, but they don't know that it is these strange and strange things that help the West's science and technology and military development at a high speed, and their footprints are all over the world, while our dignified China is still being invaded by foreign tribes, which is really hateful! My Chinese scholars have been poisoned by Confucius and Mencius for a long time! ”

“……”

Yang Wenli answered Wang Rucheng's question, and took the opportunity to extend the play, talked about the scientific and technological gap between the West and China, and finally criticized Confucius and Mencius, so that Wang Rucheng was at a loss, he learned Confucius and Mencius since he was a child, and has always regarded Confucius and Mencius as the guide, but now the general is criticizing them, one side is an ancient sage, can not be slandered casually, one side is the top superior, he can not refute out loud, so he had to be embarrassed speechless.

"I know that you are difficult to accept for a while, I don't blame you, you follow me to engage in scientific research, and after a long time, you will know that some miscellaneous studies are also very useful, far from what Old Master Kong can understand."

What did Wang Rucheng think in his heart, Yang Wenli was clear in his heart, if the ancient scholars wanted to change their concepts, they couldn't do it with just a few words, so he went on to say so.

Polishing glass is completely artificial, this is water grinding kung fu, Yang Wenli told Wang Rucheng to take care of it, and returned to the consulate general with the rest of the slave soldiers.

He had a short time to spare, and now the glass mirror and bone china have not been fired, the fleet cannot go to sea to trade with the Japanese and Koreans, and the soldiers of the Black Armor Army are not qualified, nor can they go to attack the tunbao of Jiannu.

Of the more than 3,000 black-armored troops, he planned to develop as a seed army, and he did not dare to bear any losses, and the soldiers' combat skills and strength were not up to standard, so he would never dare to fight easily.

To compete for the world with Jiannu, the number of people must be in the tens of thousands, and then the slave soldiers, he will not plan to have such a high standard, it will be too time-consuming, and it will not be successful in a few years. Therefore, he planned that the slave soldiers in the future would be complete cannon fodder, and the source of the slave soldiers was the Jiannu soldiers who were captured on the battlefield, whether they were Manchu or Liaodong Han people, Koreans and other armored people, all of them were reduced to slaves, and when they went to the battlefield, they were ordered to escort them to take the lead, and their elite soldiers used bows and arrows in the rear to assist remotely.

In fact, Yang Wenli's set is to learn from Jiannu and the thief, both of them are masters in this, Yang Wenli can only defeat them if he learns their "advantages".

Of course! The promotion system he instituted was still in effect, regardless of whether the slave soldier was full or not, and in this regard, he valued credibility more than life.

The ancients actually didn't have so many nation-state concepts, that was the slogan of the upper class of profiteers, and the ordinary people at the bottom were illiterate and did not understand so many great truths, and only the word "profit" was effective for them.

Moreover, the Jurchens are not monolithic, the so-called Manchus are just the integration of Nurhachi's conquest of various ethnic groups in the northeast, and they actually have a deep blood feud within themselves, but the old slaves use interests to envelop them, thus covering up the contradictions.

Moreover, the Manchus are also divided into strict hierarchies, there is a huge difference in identity between the ordinary Jurchens and the Jianzhou Jurchens, and there are five major generals when the old slaves rebelled, and their tribes are also Jurchen nobles.

Yang Wenli's ambition is constantly changing with the development of the current situation, at the beginning, he just wanted to protect himself, so that he could hide on a certain island overseas and be free.

But since his five young men easily defeated a group of Jiang bandits with more than 200 people, he realized that his special training method was very awesome, and it seemed that he could have a powerful army as long as he copied it?

That's why he came up with the idea of dominating the world, and then he attacked Happy Valley, which strengthened his idea. Now that he has more than 3,000 elite armor soldiers, he thinks about the problem more long-term.

For example, if he conquers Asia in the future, or even conquers the whole world, then he should dilute the concept of nationality, Han nationalism, which is the biggest obstacle to the conquest of foreign countries and races.

Therefore, from the beginning of his conquest of the Jurchens, he deliberately downplayed the concept of nationality, and only used a unified force and a unified regime to win over the people under his rule.

The United States is a multi-ethnic immigrant country, and China does not discriminate against any sect, but these two superpowers seem to be doing well, and they have become the two superpowers in the world, which is enough to prove that the systems of the two countries have merit.

It is the advantages that must be absorbed, people are not born to know everything, absorb the strengths of others, and avoid the shortcomings of others, this is what a reborn person should do.
