This is still taught to him by Zhao Kuo, before that, no one had ever considered the value of the captives from an economic point of view, and if they were kind, they were all locked up like Le Yi, and when they were replaced by cavalry robbers, Nakata schemed and cut off all their noses.

If you are ruthless, you will kill them all like Bai Qi.

After listening to Zhao Kuo's analysis, Zhao Jiang changed his previous thinking, no longer killing or abusing prisoners, but choosing to maximize his value.

"Listening to your words is better than reading a book for ten years." Qu Jing bowed over and said solemnly. He had never figured out such a simple question, and he suddenly felt that he had lived in vain for half of his life, but thinking that he had never thought of so many capable generals in history, Qu Jing was relieved again.

"How does this thing work? Don't you feel anything special?" Li Si touched the golden eagle twice, put it in his mouth and gnawed it twice, except that the carving was indeed vivid and lifelike, there was nothing peculiar.

Of course, with Donghu's level, it is already very rare to be able to make it vividly.

"I'll try." Yan Ju took it and wanted to see if he could break it, but Li Si hurriedly stopped, "Be careful, don't break it."

"If nothing else, it should be this thing, when General Li Mu took it out of King Donghu's arms, King Donghu's face changed." Cai Ze said with a smile.

"Just this thing can change the strength of an entire legion or even the fortune of an entire clan?" Li Si still didn't believe it, if they were just dead things, if they could have such a big effect, where would they put these living people?

"There's a lot of faith in it, but I don't know how to use it." Li Mu walked over, the strength of the Great Wall Guards was particularly sensitive to the power of Zhuhu, and as long as there was a little bit of it, it could be felt.

"Let's take it back and study it for everyone." Cai Ze said.

"It's fine." The crowd nodded.

There are so many talents in Handan, and everyone brainstorms and there is always a solution.

……

Zhao Kuo has also been busy recently, and began to write books on mathematics, physics, biology, etc., there is no way, this matter can only be done by him, and no one can replace him.

Although mathematics, physics, chemistry, etc., in this era, are still in the most primitive stage, it is the best period to carry forward.

There is no inferiority in everything, only high reading, no corrupt Confucianism to rule the world, and no layman commanding insiders.

Countless sages have overcome obstacles and blazed trails in various fields.

Just like Mozi proved the principle of light propagating along a straight line through the small hole imaging experiment, and defined the concept of time and space, naming time as 'long,' and space as 'yu,'.

In addition to the concepts of optics and space-time, Mozi has a certain amount of research on mechanics and acoustics, and even uses bamboo and wood to make a trap bird that can fly for three days in a row.

It is said that Mozi also made a wooden carriage for his mother, which was carried by a wooden man, and as a result, he lost his mother because he did not return. and lost his mother.

However, the sad thing is that 2,000 years ago, China led all regions in optics and acoustics, and after 2,000 years, China did not have any development in optics and acoustics, not even Mozi. ….

If Mozi knows, I don't know if he will feel sad for such descendants, or scold his descendants.

Nowadays, the Mo family has long since lost its heyday, and no one has been able to fully inherit Mozi's technology, although there are still drawings, but no one has been able to make Mozi's trap birds and wooden carriages.

As for the research of chemistry and biology, it can be said that it is almost equal to zero, and the only thing that is close to chemistry is the group of alchemy monks, and finally came up with gunpowder, but unlike Mozi's systematic research summary, those guys just want to refine the elixir to look better, so as to cheat the funds, and it has nothing to do with the study of gunpowder, but it happened to come out.

The farmer's biological research is limited to food, and there is no other aspect.

Not to mention some things that are ahead of the times, basic mathematics, physics, chemistry, biology, etc. Zhao Kuo still has to come out, and there are millions of people in Zhao Kingdom, and there may not be nothing in the future

There can be another Mozi who will push science and technology forward for hundreds of years.

The microscope used for research has also been made, although the multiplier is not too high, but it is enough to support the current research, the lens is polished with crystal, and there are only three in the entire Zhao Kingdom, which are in the hands of the doctor, the Mo family and the farmer.

As for the microscopes that need higher magnifications in the future, they will have to rely on themselves.

Zhao Kuo is responsible for leading the door, and it depends on them personally to what level of cultivation they reach.

"I'm so tired!" Zhao Kuo shook his head and said helplessly.

Even with paper, writing with a brush is still a bit unaccustomed, and it is completely impossible for those people to write hard.

What made Zhao Kuo even more devastated was that after compiling these books, he had to teach his students, and after teaching others, he would let others hand them over to others, so that he could be the shopkeeper.

It's impossible to just throw it away and let them learn it on their own, it's an absolute genius to learn.

"Let Mo Feng find a few smarter students between the ages of fifteen and twenty-five." Zhao Kuo said to the guards.

Zhao Kuo decided to teach while writing, in case there is a mistake, it is easy to revise, after all, after so many years after graduation, although the mental power has been strengthened, the memory is inevitably a little ambiguous, and it is normal for mistakes to occur.

The guards had just walked out, and Song Zhen walked in.

"Is there something wrong with Mr. Song?" Zhao Kuo asked.

"That's right, King, our research has reached a bottleneck, and I want to ...... I want some corpses to study." Song Zhen said with some hesitation, it is still very shocking to use corpse research in this era, and he also took great courage to ask Zhao Kuo, that is, Zhao Kuo has always been very open-minded, and Song Zhen will not open his mouth if he changes the monarch.

"I almost forgot about it." Zhao Kuo patted his head, "It was hot before, and the corpses were not easy to store, so they were all buried. I will inform Li Mu to keep a few corpses and keep them with ice. In addition, I will transfer a few death row prisoners and prisoners over, and the loss of one death row prisoner is much better than the loss of my people of Zhao Kingdom."

"Thank you, thank you, King." Song Zhen practiced and bent over, he was ready to be rejected, but he didn't expect Zhao Kuo to agree so refreshingly.

"In the future, any need can be said by the widow, and the widow who can meet it will be satisfied." Zhao Kuo said.

As long as a physician can cure a disease, he can live countless lives. Moreover, if Zhao wants to develop southward in the future, all kinds of miasma and poisonous insects will have to be solved by doctors, and there will be no loss.

"It's really a blessing for my doctor to have the king here." Song Zhen said with great joy.
