Some of the boats there almost capsized. The key problem is that the Ming Dynasty lacks nautical charts for many areas, and it is now difficult to locate at sea."

"Sea positioning?"

"That's right!" Zheng He nodded, "I use the method of star-catching, but sometimes, especially at night, the fog on the sea is very heavy, and the line of sight is limited. You can't see the stars in the sky at all, so on the sea

Navigation is very dangerous, especially on the sea at night, so you need to be more cautious. If you are not careful, you may deviate from the route. After all, on the chart, a slight deviation can cause a mistake of thousands of miles. "

"I have never heard of these statements." Zhu Di narrowed his eyes slightly and murmured.

Zhu Di turned around and asked Yan: "Does Master Dao Yan know the art of star pulling?"

Dao Yan shook his head, he really didn't go out of his way to understand it.

Zhu Di and Zheng He finished chatting about what they had seen in the stone ponds thousands of miles south, and then continued to chat about all the news Zheng He had heard about overseas. They learned that the sea is so boundless, and that overseas countries are completely different from the Central Plains.

Zhu Di greatly broadened his horizons and knowledge.

After all, it is impossible to read the Yuan Dynasty classics about overseas content as intuitively as listening to Zheng He's personal experiences.

"It seems that the Ming Navy's ships and related navigation technology still need to be improved to adapt to long-distance voyages. It is best to create a better positioning method than the star-finding technique."

After hearing what Zheng He said, the Ming Navy now had to rely on the star-pulling technique passed down from the Song Dynasty and the Semu navigators if they wanted to sail far or to the Western Ocean. Zhu Di couldn't help but sigh.

After all, it's not the same thing to always rely on outsiders. If you want to go underground to the West on a large scale, you have to find your own way.

Zheng He hesitated for a moment and finally told the truth.

"Your Majesty, it would be very difficult for Ming Dynasty to do this."

"Why?" Zhu Di asked with a frown.

Zheng He smiled bitterly and said: "The Song Dynasty only dared to sail close to the coastline when conducting overseas trade. Otherwise, the sea is vast and boundless, and it is easy to lose your way. How can you easily achieve positioning on the sea? Star-finding is already the best way.

"

"oh."

Zhu Di nodded and said suddenly.

"Why don't you ask Jiang Xinghuo?"

Zheng He's expression froze.

You must know that Jiang Xinghuo often creates trouble for him.

Regarding the matter of contacting Jiang Xinghuo, Zheng He was unwilling to do so, let alone a close contact.

It's not that Zheng He doesn't believe in Jiang Xinghuo's abilities.

Zheng He believed too much in Jiang Xinghuo's extraordinary abilities!

The problem is that Jiang Xinghuoguang moves his mouth!

As a result, Jiang Xinghuo said that he would go to Wanli Shitang to look for bird droppings, and Zheng He would have to break his legs and not come back for two months.

Zheng He was also ridiculed by some villains as "repaying the court with shit", which almost made Zheng He angry.

Therefore, Zheng He really didn't want to ask Jiang Xinghuo.

Otherwise, I don’t know how many troubles Jiang Xinghuo will cause for himself if he talks.

Zhu Di laughed and said: "Okay, let's talk about what you saw in the literacy class in the imperial prison."

After Zheng He finished describing it, Zhu Di nodded. Apparently, he was not too surprised that Jiang Xinghuo could solve the literacy problem.

"so."

Zhu Di mused: "Jiang Xinghuo has the last four classes and is about to be released from prison."

"Originally, Mr. Cao Guo is on a mission to Japan, and there is a shortage of someone to act as a mouthpiece for me. If you don't know about it now, it will be a big mistake for you. You should go to jail."

Zheng He's lips moved with difficulty.

In the end, it’s like when your leader says, “Thank you for your hard work,” you can only reply, “Good leader.”

Zheng He said: "My lord, I obey your order."

If you bring shit back to the court, you will be rewarded with jail time.

Jiang Xinghuo, I really thank you!
