Li Jie originally came with Liu Ying, but now he was relieved to see that Liu Ying was fine, but he didn't expect to be called by Lao Zhu to stay, which made him worry all of a sudden, after all, Lao Zhu has too many moths, and the ghost knows what he will arrange for himself?

"The news from Ningbo Port that Zou Pusheng has almost trained the first batch of troops, and after Zhang Dingbian returns, they will be able to send troops to Tsushima Island immediately!" Zhu Yuanzhang said slowly.

"So fast!" Li Jie was also shocked when he heard this, but it was normal to think about it, Zhang Dingbian went to recruit people, and Zou Pusheng had already started training, and the two sides were carried out at the same time, and Zou Pusheng and these people lived overseas, and they also needed to be protected by force, so as long as they trained a little, they could go to the battlefield.

"Then where is Master Mu Jiao, has the recruitment of nine fishermen been over?" Li Jie asked again.

At the mention of Zhang Dingbian and the fishermen surnamed Jiu, Lao Zhu's face became a little unsightly, but he still replied: "Zhang Dingbian has arrived in the northern part of Zhejiang, and the fishermen with the surname Jiu have almost been recruited, and now the first few groups of fishermen have arrived at Ningbo Port, and it is estimated that he is about to go back." ”

"Great!" Li Jie also slapped excitedly when he heard this, his previous plan finally began to be implemented, this is not just to solve the Japanese Kou, not just for Iwami's silver mine, the most important thing is to open a hole in the sea ban, and even this may be the beginning of the Ming Dynasty's road to sea power!

"You're so happy, that's a coincidence, a month later, the matter of escorting Zhang Dingbian and them to Tsushima Island will be handed over to you!" Zhu Yuanzhang was unhappy when he saw Li Jie's excited appearance, and immediately spoke.

"Obey the order!" Li Jie agreed without hesitation, the whole plan was proposed by him, of course he wanted to see the implementation of the plan with his own eyes, so even if Zhu Yuanzhang didn't let him go, he wanted to fight for it.

Seeing Li Jie agreeing so happily, Zhu Yuanzhang was even more unhappy, in his opinion, going to sea is a chore, and there is a certain degree of danger, and he must be reluctant to be an ordinary official, but he didn't expect Li Jie not only to agree, but also to be very excited, which made Zhu Yuanzhang feel like he was punched in the air, and his whole body was uncomfortable.

However, Zhu Biao next to him stood up at this time and said: "Father, Li Jie and Yuning are already engaged, and it is really not appropriate to take risks, I think it is better to leave this matter to someone else!" ”

I have to say that my father-in-law still feels sorry for his son-in-law, but Zhu Yuanzhang immediately refused: "The plan was proposed by him, of course he has to participate in it, and those people in Zhang Dingbian only believe in him, if he doesn't go, I'm afraid others won't be able to do this at all!" ”

"Your Highness, although there is a risk in going to sea, as long as you choose a good route and time, the risk is still very small!" Li Jie also said at this time that he didn't want to miss such a good opportunity to go to sea.

Zhu Biao's father's refusal was not surprising, but he didn't expect Li Jie to want to go like this, which made Zhu Biao not say anything.

"Since you want to go so much, then prepare and leave for Ningbo in half a month!" Zhu Yuanzhang said at this time, the fleet will not leave until a month later, and Li Jie will go half a month in advance, so he can also familiarize himself with the situation.

"Ministers and Li Jie obey the order!" Li Jie saluted again.

At the same time, Xie Jin with full of doubts, finally came to the hot air balloon workshop next to the Ordnance Bureau, here he is also the first time to come, it turned out that there are soldiers guarding the door, after all, now Da Ming is studying the use of hot air balloons in the army, it is estimated that this place will also become part of the Ordnance Bureau in the future.

Xie Jin lingered outside the door of the hot air balloon workshop for a while, hesitating whether to go in, but at this moment, he suddenly heard someone behind him say in surprise: "Master Xie?" Why are you here? ”

Xie Jin felt familiar when he heard the voice, and immediately turned around, but found that the person behind him he knew, it was Guo Zhenglin of Qin Tianjian, speaking of which Guo Zhenglin was also young and promising, and he had a deep knowledge of astronomy at a young age.

"Brother Guo, why are you here?" Being able to see acquaintances here, Xie Jin also asked in surprise.

"Huh? This is where our Qin Tianjian is in charge, I want to know why you are here, Brother Jie? Guo Zhenglin was also stunned when he heard this.

Since the appearance of the hot air balloon, they Qin Tianjian has been involved in it, although the entire hot air balloon workshop was built by Li Jie, but now it is managed by Qin Tianjian, and the improvement of the hot air balloon is also done by them, after all, most of the astronomy are erudite, otherwise Zhang Heng would not have designed the subtle instruments such as the geokinetic instrument and the armillary sphere.

Knowing that the hot air balloon workshop actually belonged to Qin Tianjian, Xie Jin was also surprised, could it be that Li Jie let him come here to have something to do with Qin Tianjian?

"Brother Xie, you haven't answered my question yet?" At this time, Guo Zhenglin came to Xie Jin and asked again.

"This ......" Xie Jin hesitated for a moment, and finally spoke, "Actually, I was drinking with Li Banyu yesterday, and he instructed me to come here." ”

"It turned out that Li Banyu asked you to come, so it's not surprising, let's go, let's go in together!" Guo Zhenglin also immediately showed a sudden expression when he heard this, and immediately laughed and grabbed Xie Jin and was about to go inside.

"Brother Guo, do you know what Li Banyu asked me to do?" Xie Jin was a little confused at this time, why did Guo Zhenglin seem to know something when Li Jie's name was mentioned, and he pulled him in without asking anything?

"Of course I know, speaking of Brother Jie, you are erudite and talented, I should have thought of inviting you to come!" Guo Zhenglin also showed an annoyed expression at the end, he had forgotten about this great talent before, but fortunately Li Jie invited him to come.

"So what am I going to do?" Xie Jin asked curiously again, he didn't know what he was going to do, why did Guo Zhenglin know?

"Let's go, we'll be there in front, and you'll understand when you're in!" Guo Zhenglin deliberately sold a pass at this time, and then pulled Xie Jin to speed up his pace.

Confused, Xie Jin could only follow Guo Zhenglin, and soon came to a house that looked quite ordinary on the outside, when they entered the room, Xie Jin found that the room was already full of people, some of whom he still knew, most of them were officials of Qin Tianjian, but some seemed to be people from the Ministry of Industry.

"Brother Jie, you are a coincidence, today is the stellar theory that Wang Yue and Wang Sichen talked about, this is the latest doctrine that Wang Sichen and Li Ban have come up with after reading and discussing, and our Qin Tianjian has proved part of the correctness of this doctrine!" Guo Zhenglin said excitedly again.

"What is a star?" Xie Jin asked puzzled again, he also had some research on astronomy, otherwise he would not know Guo Zhenglin, but he had never heard of any stars.

"The so-called stars actually refer to the sun, which can shine and heat the celestial body, the earth where we are located, and the surrounding celestial bodies such as Venus and Jupiter, all revolve around the sun, but the sun is not fixed, but moves in a way that we cannot understand for the time being, which is the biggest breakthrough in our astronomical history!" Guo Zhenglin excitedly introduced.

"We revolve around the sun? How is this possible? Xie Jin was skeptical when he heard this, after all, this matter was too contrary to his intuition.

"You may not be able to understand this for the time being, but believe me, as long as you listen to a few more lessons, you will soon be able to figure out the reason!" Guo Zhenglin didn't explain, but pointed to the front desk, because Wang Yue, who was in class today, had already stepped onto the podium and was about to start lecturing.

Xie Jin also looked at Wang Yue on the stage curiously when he heard this, just now he heard Guo Zhenglin call the other party Wang Sichen, he knew that Si Chen was a petty official from the ninth grade, and the green official uniform on the other party also confirmed this, but the officials below sat upright one by one, and did not despise the other party because of his low grade.

Compared with the previous sloppy, the current Wang Yue seems to have changed a person, although the official uniform on his body is a little old, but it is very clean, the beard on his face is also trimmed, and the whole person also exudes a kind of vitality, which is more than ten years younger than before.

"Ahem~, what I want to talk about today is why the earth, Jupiter and other celestial bodies rotate around the sun and will not break away, for this question, after I discussed it with Li Banyu, Li Banyu put forward a conjecture, that is, between the celestial bodies, there is a force that we can't see, just like magnets attract each other......"

The content of Wang Yue's lecture is very novel to the following people, sometimes a sentence can solve the problems that have plagued many people's hearts for many years, of course, this will also make them have more questions, but no one bothered during the lecture, because there will be a period of free discussion later, when they can speak freely.

This kind of public lecture was originally created by Li Jie, but sometimes Li Jie couldn't come to something, so slowly other people began to give lectures on stage, and now it has formed a tradition, as long as you think your views are correct, you can give a speech on stage, of course, there will definitely be people who will refute the views later, as long as you can refute everyone, then your views can be recognized by everyone.

Xie Jin listened to the content that Wang Yue listened to, some things he could understand, and some of them became more and more confused, on the other hand, Guo Zhenglin beside him, but his eyebrows flew when he listened, and he recorded some content from time to time.

This made Xie Jin feel shocked, after all, he has been known as a prodigy since he was a child, no matter what Mr. says, he can come back to him, and there has never been such a situation today, which makes him doubt himself, is he not as smart as he imagined?

Just when Xie Jin fell into self-doubt, two more people walked into the classroom lightly, it was Li Jie and Zhu Yunxi, who came late, because they discussed with Zhu Yuanzhang about going to sea, so they delayed a little time, and he also saw Xie Jin bowing his head and contemplating at a glance, which made Li Jie also smile slightly: Xie Jin finally did not let himself down!
