The beginning and development of science and technology, to put it bluntly, is the beginning and growth of mathematics, physics and chemistry.

Mathematics doesn't need Zhu Zhanyan, because the last number in the six arts of the gentleman, music, archery, royalty, calligraphy, and number is mathematics.

Of course, today's mathematics is not comparable with the mathematics of later generations, and it is even inferior to the junior high school curriculum of later generations, but after all, the foundation is there.

The really hard ones are physics and chemistry.

Physics and chemistry were also used in ancient times, but very few, what Zhu Zhanyan had to do was to open this head, as for the follow-up ......

Although he was very reluctant to admit it, Zhu Zhanyan still had to admit that he couldn't do it, it was already good that he could open his head, and he didn't have to think about anything in the future.

A few years ago, when he was in Xiangzhou Mansion, he took the time to write some things about physics and chemistry, but at first he wanted to systematically write down the courses he had learned.

But then he found out that no.

The first is that too much time has passed, and he has almost forgotten it, and the second is that in fact, these things were basically returned to the teacher before he came to Daming, and the rest is just a little more than the so-called common sense.

If you want to compile a set of systematic teaching materials, this is a big test for Zhu Zhanyan's memory, and it will take too much time in addition.

He didn't have the time, so he had to make a start.

However, with the current situation of the Ming Dynasty, basically as long as the descendants of the future generations are not losers to the extreme, it should be no problem to walk in front of everyone.

Chen Xun wanted to persuade Zhu Zhan Yan, because he knew Zhu Zhan Yan better, and knew that Zhu Zhan Yan was just a preliminary plan, and there would be follow-ups.

Chen Xun believes that this kind of investment without a guarantee is not very worthwhile, because you can't be sure if you can make a weapon like white phospho eggs.

But in the same way, Chen Xun also knew that Zhu Zhanyan was actually a very stubborn person in some aspects.

Previously, Chen Xun had persuaded Zhu Zhan on the excavation of the Suez Canal, asking him to restrain himself and not kill too much, after all, it takes a lot of people to dig the canal.

But Zhu Zhanyan still went on a killing spree in the Timurid Empire, and there were basically no more than any of the men in the peptide.

Therefore, Chen Xun did not stop it this time.

Today's Ming Dynasty can withstand Zhu Zhanji's profligacy, and there is no reason why Zhu Zhanji's profligacy cannot be resisted.

Besides, Zhu Zhanji is much more restrained than Zhu Zhanji, after all, he just spends money and food, and Zhu Zhanji almost gave all the money of Daming's family to Wara.

However, although there is a "gift" from Zhu Zhanji, Wara's current situation is not good.

On the tenth day of the first month of the first month, the envoys of Warat, who had entered Beijing to pay tribute years ago, had not yet returned, and another envoy of Warat came to Shuntianfu.

And this time, this late Warat envoy came with a heavy gift.

"Envoy of the Warat Ministry, meet His Royal Highness the Prince!"

He knelt on the ground respectfully, not only did he have the etiquette in place, but his attitude was not even more reasonable.

"Yi Ra Si ......" Zhu Zhanyan looked at the people below, his eyes narrowed.

"If this son is not mistaken, your father...... It should be Bald Polo, the king of Anle, right? ”

"His Royal Highness the Prince of the World really has a good memory, and his father is King Anle."

was told out of the house by Zhu Zhan, and it was without explaining or reminding him in advance, which made Yirasi's heart tighten.

If the relationship between the two countries is good, just like the current Ming and North Korea, then this is a good thing, but what about the relationship between the Ming and Warat......

That's not a good thing......

"Bald Polo's son......" Zhu Zhanyan nodded while bypassing the bookcase and walked in front of Yi Rasi.

"Although I haven't seen your father, I don't know if you are like your father, but as the son of King Anle and a native of Mengyuan, how did you get a Confucian statue?"

"Hui Shizi, His Royal Highness." Yirasi's heart was slightly relieved, but he didn't dare to raise his head for a moment.

"The villain has been reciting Confucian classics since he was a child, and rarely rides a horse to go on a safari, which may have something to do with this."

Zhu Zhanyan raised his eyebrows and didn't say anything.

In fact, Zhu Zhanyan is a person who doesn't like to detour very much, although he has done a lot of detouring things, which is commonly known as conspiracy, but it is all a last resort.

In contrast, he still prefers Yangmou, such as directly letting Yang Pu go to Warat and die there.

"Alright, the envoy who sent the tribute has not returned, so you have sent someone again, and it is the son of Vulture Polo."

"What do you want to say? Or rather, what do you Valat want to make up for? ”

"Hui Shizi, His Royal Highness." Elasi knelt on the ground, feeling a little numb in his knees and a numb scalp.

Because, that's the way to get to business.

"The villain actually came to apologize to the Ming Dynasty this time, before the Ming envoy was killed in Hulan, our Warat Department has found the real murderer, and sent the real murderer over."

"I hope that His Royal Highness will not make a big fuss and forgive us for the negligence of the Warat Division."

"Oh?" Zhu Zhanyan's eyebrows were raised, and his tone was slightly raised.

"Found the real murderer? It's fast, you can't just find someone to fool me, right? ”

"His Royal Highness the Prince of the World laughed, how dare we be so bold?"

Seeing that Zhu Zhanyan was not as unreasonable as he had expected, Yirasi's mood also calmed down.

"The real murderer resisted fiercely when he was arrested, and my Warat Department had no choice but to kill him in order to capture the real murderer to Daming."

"The first-level villain of the real murderer has also been brought on this trip, but it is not easy to take it out here, but the villain has something here, and His Royal Highness the Prince of the World will understand who the real murderer is when he sees it."

Zhu Zhanyan didn't speak, just beckoned.

Zhu Ping quickly stepped forward, took the things that Yirasi took out of his arms, and after repeated inspections, he turned around and handed them to Zhu Zhanyan.

"Yo-hee." Zhu Zhanyan couldn't help but be shocked when he saw that thing.

"Is he the real culprit? Or ......"

"Tsk." Pinching the token in his hand, Zhu Zhanyan looked up at Yirasi with interest.

"It's enough to spend money, is this abandoning the car to protect the handsome and breaking the arm to survive?"

"Why did His Royal Highness say this?" Yi Rasi slowly raised his head and looked at Zhu Zhanyan in front of him calmly.

"How dare we, the Warat, deceive His Highness? Since it was brought, it is naturally the real culprit determined by my Warat Department after many investigations. ”

"If His Royal Highness doesn't believe us, then you can send someone to investigate the hypothermia in Kulan."

Zhu Zhanyan put the waist card engraved with the word Xianyi on the table behind him, with a smile on his face, and quietly looked at Yirasi in front of him.

Yi Rasi can be said to have no fear, because he knows that Da Ming will not send someone to investigate Hulan and Sudden Hypothermia, and even if it is an investigation, nothing can be investigated.

Only those who have wronged you know how wronged you are, and as the initiator, Zhu Zhanyan naturally knows how wronged Warat is.

But that's not his purpose.
