"Good thing! Good thing!" Zhu Yuanzhang raised his eyes and looked left and right, his face full of ecstasy, and he was reluctant to let go for a moment.

Zhu Biao behind him also looked at his father's performance in shock. He had not seen his father lose his composure for a long time. This made him whisper to Li Jie in curiosity: "Can this thousand-mile eye really make people see the scenery thousands of miles away?"

"Your Highness misunderstood. Qianli is just an exaggeration. Through this Qianli eye, you can see the scenery within three or five miles at most. No matter how far you are, you may be powerless." Li Jie explained that the telescope he made is still a bit rough and has a low magnification. After all, time is rushed, and you can improve it if you have time in the future.

"Three or five miles? That's quite amazing!" Zhu Biao nodded in admiration when he heard this. If Li Jie really said that he could see the scenery thousands of miles away, he would probably not believe it at all.

At this time, Zhu Yuanzhang finally reluctantly put down his eyes, staring at Li Jie with his eyes radiating, saying, "This eyes should be created by the army. If the generals and scouts in the army have this eyes, they will definitely be able to discover the enemy situation early and expect the enemy to be ahead of the initiative!"

"Your Majesty is wise and clairvoyant is indeed built for the army. In addition, it can also be used in astronomy, geography or navigation." Li Jie was very satisfied with Zhu Yuanzhang's performance. The other party was from a corps and was originally a very excellent commander, so he could definitely think of the military use of telescopes.

"Father, can you let me see this Qianliyan?" Zhu Biao, who was so itchy, finally couldn't help asking. He was too curious about this Qianliyan.

Zhu Yuanzhang was also very happy at this time and immediately handed over Qianliyan to Zhu Biao. As a result, when Zhu Biao personally experienced the magic of Qianliyan, he praised Li Jie. Although the flintlock rifle is good, Zhu Biao is not a soldier after all and cannot be used normally, so he is not deeply touched. In contrast, Qianliyan's function is to be seen at a glance.

"Li Aiqing, the last time the reward of the flintlock rifle has not been released, you actually offered such a treasure again, which makes me not know how to reward you!" Zhu Yuanzhang sat down at the desk with a smile, and even asked someone to give Li Jie a seat, and even changed his words to call Li Jie the Queen, which is very rare in the court.

"Your Majesty is so serious, these are all things that I should do!" Li Jie immediately said modestly.

"Father, isn't it another gift? Let's open it and take a look!" Zhu Biao also put down the telescope at this time and walked over excitedly, saying, "The first gift was a telescope, and the second one must be no worse than the first one."

Zhu Yuanzhang also woke up when he heard this and immediately asked someone to take a second box, saying it was a box. In fact, it was a box two feet square, much larger than the box that was equipped with a telescope, but the box was not heavy. When the box was opened, Zhu Yuanzhang and Zhu Biao and his son were stunned when they saw the things in the box. It was another thing they didn't know at all.

The eunuch took out the things in the box and put them on the desk. He saw that the thing was a big wooden ball with raised bulges at both ends, connected to the stand and rolling. Under the stand, Zechang had a round support, so that the thing could be placed firmly on the desk.

"What is this ball?" Zhu Yuanzhang asked with confusion as he looked at the strange wooden ball. He found that there seemed to be some complex patterns on the ball, which seemed to be like a map, but why was it drawn on a ball?

"Your Majesty, this ball is called a globe, which carved all the land and oceans in the world. Our Ming Dynasty is here!" Li Jie said as he walked forward, and then found the Ming Dynasty's location to point out Zhu Yuanzhang.

This globe was created by Li Jie and craftsmen from the Military Weapon Bureau, and then he personally portrayed the global map on it. Of course, he only portrayed it based on his memory. There is no shortage of seven continents and four oceans, and even some important islands are there, but the shape and location are very wrong. If someone sails according to the map above, he may not even know how to die.

"Wait! What do you mean is that the earth where we live is a ball?" Zhu Yuanzhang widened his eyes when he heard this, with an expression of incredible belief. Although he is one of the most outstanding emperors in history, he is also the emperor with the lowest background, and his knowledge reserves are worse, especially in astronomy and geography.

"Isn't this the legendary Huntian saying?" In comparison, the prince Zhu Biao is stronger than Zhu Yuanzhang. After all, he has received orthodox royal education and is not unfamiliar with astronomy and geography.

"What is the Huntian Theory?" Zhu Yuanzhang asked immediately.

"The sky is like a chicken, the celestial body is like a projectile, and the ground is like a yellow in the chicken." Li Jie smiled and explained, then he shook his head again, "This description is actually not accurate, but one thing is correct, that is, the earth is like a chicken egg, all the creatures in the world live on this sphere!"

"This... how is this possible?" Zhu Yuanzhang looked disbelief when he heard Li Jie's explanation. If it weren't for the telescope that Li Jie had presented before, he might have driven Li Jie out as a liar.

"I also understand Huntian's saying, but if we live on one ball, if we look up, wouldn't the people on the other side fall down? " Zhu Biao immediately asked, this is also a problem that the ancient Huntian's saying cannot be explained.

"This question of Your Highness the Crown Prince is actually easy to answer. I'll demonstrate it to Your Majesty and the Crown Prince!" Li Jie said with confidence, as if he had expected someone to ask this question.

Li Jie picked up the globe and quickly walked out the door. Zhu Yuanzhang and his son followed curiously. After Li Jie came outside the door, he actually rolled the globe on the ground for a few times, and then took it back to show them to the two: "Your Majesty, please see, what is more on this globe?"

"Dust?" Zhu Yuanzhang immediately replied as he looked at the dirty globe in front of him. Li Jie rolled a few times on the ground. It was strange that he was not stained with dust. However, the warm pavilion was spotless. No wonder he had to run outside.

"Yes, it's the dust. The earth we live in is too big. For the earth, we humans are like grains of dust on this globe. Even if we turn the globe, the dust will not fall down by itself!" Li Jie explained with a smile. He wanted to use gravity to explain, but Lao Zhu and his son definitely don't understand it, so it's easier for them to accept it using this example.

"It makes sense. After saying this, Huntian said it is very reasonable!" Zhu Biao also showed a thoughtful expression when he heard this.

Zhu Yuanzhang also showed a meditative look. After a while, he suddenly spoke and ordered: "Xuan Qintianjian!"
