Zhu Neng accompanied the Liu family's father and son back to Peking.

This guy's eyes were red. He didn't sleep well last night. He tossed and turned all night. It was not that the Lu family's house was uncomfortable. A warrior like him could sleep soundly even if he was camping in the wild. The key was that what Liu Chun said made him incredible. He flew to the sky and sent messages from thousands of miles away, just like what he wrote in a verbal book.

Is Guo’s academic knowledge really so powerful?

Zhu Neng is less than 20 years old now, and he is very curious. His father is a martial artist. From childhood to adulthood, he practiced martial arts with his father. When he was fourteen or five years old, he followed the army to fight. Recently, he inherited his father's position and became a thousand households.

What Zhu Neng knew was limited to military camp wars. When dealing with the Lu family, he could only think of ways to fight against the military. Liu Chun's words opened a brand new door for him.

Along the way, he kept peeking at Liu Chun, looking like he was eager to speak but stopped.

Liu Chun was aware of it and suddenly turned around and smiled, "Zhu Qianhu, just say whatever you have. We are all old friends."

Zhu Neng swallowed, stretched his neck, and tentatively said, "Well, Brother Liu, what are you learning? Can you tell me... Just say something." He scratched his head again, and smiled silly, "Don't be afraid, I am a stupid person, just listen to a lot of fun, it won't spread."

Liu Chun laughed, "Zhu Qianhu, you are wrong. Our Guo family studies the truth. What is truth? It means that no one can draw the same conclusion as long as they follow the same method. We are different from those Confucian scholars, and there is no question of disagreement or ambiguity."

Liu Chun rode on the horse and suddenly pointed to a pavilion in the distance.

"Zhu Qianhu, look."

Zhu Neng looked at it in a pavilion, and couldn't help but frown and said, "What's so strange? Could it be that you transformed it?"

This guy fell into the hole of gods and ghosts and couldn't pull it out.

Liu Chun shook his head and said, "Did I say what did you see first? Is it the whole pavilion or the top of the pavilion?"

"This... is naturally the top, just like the cavalry of the Tartars. From a distance, they must first see their banner, then the people, and finally the war horses... Is that right?"

Liu Chun said: "Zhu Qianhu, of course you are right, but have you ever thought about it? If the ground is flat and from far to near, the object will only grow bigger and bigger, and will not be exposed above first, and then below. Think about it, what does this mean?"

Zhu Neng's head was starting to be insufficient, "What does this... mean?"

"It means there is a curve!" Liu Chun bent his left hand, and his two fingers on his right hand acted as his legs, demonstrating Zhu Neng the process from far to near, and then smiled and said, "If each place meets this rule, there is only one explanation. We are standing on a huge sphere!"

"What?"

Zhu Neng almost fell off the horse's back, "I said to Brother Liu, what are you talking about? How could we stand on the ball? How big should that ball be? Who can play it?"

Liu Chun was amused and crying, "This is what our Guo family studies. We not only think that there is a ball under our feet, but the ball is still rotating. It is precisely because the ball is rotating that there are all seasons of the year, and this is how "Time Calendar" comes from!"

After Liu Chun finished speaking, he continued to beat the horse forward, and Zhu Nengze looked confused... No, right? This guy was talking nonsense? But he looked at the ten-mile long pavilion that was getting closer and closer. Indeed, there appeared in the middle of the pavilion. Going forward, the base appeared... How to explain this? If it was flat, you should see the upper and lower ones at a glance, rather than gradually revealing it!

Yes, but Liu Chun’s speech was too incredible. This future prince was caught in a battle between heaven and man. Do you believe in reason or years of experience... This damn Guo’s learning is really harmful!

Zhu Neng was confused and returned to the Yan Prince's Mansion and met Zhu Di.

In just a few days, Zhu Di seemed to have grown taller, more energetic and more majestic. He promptly reported the military information about the Jinyiwei incident. Although Old Zhu did not directly reward anything, letting him go to war with several famous generals is the biggest reward!

Among the earliest brothers who were in the vassal state, he was the first!

Who is less than thirty years old, not to mention Zhu Di!

Old Zhu has more than 20 sons, both of whom are royal blood, should fight hard for who is the most like his father!

When Zhu Di saw Liu San and Liu Chun and his son, he did not put on airs, but gave him a seat. When they sat down, Zhu Laosi was straight to the point.

"Liu Baihu, the saint issued an order, and the army gathered, preparing to attack the Northern Yuan Dynasty. You have made great contributions to the country." After a pause, Zhu Di said again: "However, the court is not familiar with the Liaodong area, and it still needs to explore the roads and be the vanguard of the army."

Zhu Di didn't continue talking, but he already understood the meaning. You can go and have another trip!

Who made you familiar with the situation?

The person above moves his mouth, and the person below runs and breaks his legs.

There is nothing to say about this.

If you can do it, you will naturally have a generous reward, but if you can't do it, you will have to die on the grassland if you have an accident!

In the past, Liu San was determined without hesitation, but after this incident, he hesitated.

Liu Chun stood up suddenly and stood up, "Report to the prince, auspicious treasures come from heaven, the grass people congratulate the King of Yan and the Ming Dynasty!"

Zhu Di frowned and sneered: "Young man, what tricks have you made? Could it be that God has predicted?" Zhu Di still remembered that Daoyan said that this kid is proficient in astronomy and can see the destiny of heaven.

Liu Chun dared not admit that he and the demon monk Daoyan were different, and it would be bad if he was treated as a charlatan.

He hurriedly took out the sheepskin map from his arms and presented it with both hands.

"Prince, this is the map left behind when the ancestor traveled thousands of miles and surveyed the "Shi Calendar". It happened to be part of the Liaodong area. The grass people presented it to the prince, wishing him a victory in the flag and success!"

"What?"

Zhu Di suddenly stood up, walked over and snatched it.

After the unfolding, Zhu Di was overjoyed!

Mountains, rivers, towns, villages, tribes, and even water sources are all marked. What scientists pay attention to when doing things is rigorous.

Guo Shoujing drew pictures at that time, which also left convenience for future generations. Whoever wanted to continue researching could re-take the path of exploration according to his map.

Who knew that after his death, the Yuan Dynasty would be corrupt and chaotic, and no one would care about astronomy for a long time.

Zhu Di became more and more excited as he looked at it. He found that he even marked several gold mines on the map!

"What? There is still gold in Liaodong?" King Yan exclaimed in dismay.

Liu Chun rolled his eyes, "That's natural. The gold mines in Liaodong were discovered in the Han and Tang Dynasties as early as the Han and Tang Dynasties. According to the notes of his predecessors, there are probably more gold mines in Liaodong than in the entire Ming Dynasty!"

"What you said is true?"

Zhu Di widened his eyes, waved his fists suddenly, and shouted excitedly: "This time, the troops will surely break through Liaodong!"

While excited, Zhu Di actually sent an order to ask his family to have a drink, and he wanted to invite a banquet for the Liu family father and son.

Soon, the fat little boy Zhu Gaochi, the naughty child Zhu Gaoxu, and the princess Xu Miaoyun all arrived.

Zhu Gaochi seemed to have lost weight, but his face was still round and his touch was absolutely first-class, which made people want to pinch it for a while. The little fat man took the initiative to come to Liu Chun and secretly told him that his mother asked his second brother to do exercise with him. Zhu Gaoxu was unwilling to do it, and he also twisted his butt with disgust on his face, which was so funny.

During the meal, Zhu Di said, "You two gangsters must be obedient. This time the father will follow the army to go to war. No trouble is allowed in the mansion!"

My father is leaving?

Zhu Gaoxu was happy. He was not afraid of me. Without my father, nothing I said would work. As for the "big meat ball", oh, I didn't twist my butt with him. It's too childish!

When Zhu Gaochi heard this, he was stunned for a moment, and then his face was full of sorrow and lowered his head silently.

He secretly looked at Liu Chun next to him, "Will it be very hard to go to the battle?"

Liu Chun nodded, "That's natural, general..." He wanted to say that the general died in hundreds of battles and the hero returned for ten years, but he felt it was unlucky, so he swallowed the words.

"The prince will definitely win a great victory in this battle. The eldest son just wait for good news!"

Zhu Gaochi was not canonized as the crown prince, so he could only be called the eldest prince.

The little fat man puffed his cheeks and his face immediately turned into a ball. "Just wait, I can't make anything for my father, it's useless!" He was in a bad mood, and after eating three bowls of rice and five buns, he put down his chopsticks.
