"Good stuff! Good stuff! Zhu Yuanzhang held his clairvoyance and looked left and right, his face was full of ecstasy, and he was reluctant to let go for a while.

Zhu Biao in the back also looked at his father's performance in shock, he hadn't seen his father lose his temper for a long time, which made him curious and whispered to Li Jie: "This clairvoyance can really make people see the scenery thousands of miles away?" ”

"Your Highness has misunderstood, thousands of miles are just exaggerations, through this clairvoyance, at most you can see the scenery within three or five miles, and I am afraid that you will not be able to do anything if you are far away." Li Jie explained that the telescope he made was still a little rough and the magnification was a little low, after all, time was in a hurry, and it could be improved later when there was time.

"Three or five miles? That's pretty remarkable, too! Zhu Biao also nodded approvingly when he heard this, if Li Jie really said that he could see the scenery thousands of miles away, I am afraid he would not believe it at all.

At this time, Zhu Yuanzhang finally reluctantly put down the clairvoyance, stared at Li Jie with bright eyes: "This clairvoyance should be made for the army, if the generals and scouts in the army have this claireye, they will be able to discover the enemy situation as soon as possible, and anticipate the enemy's opportunity!" ”

"Your Majesty is wise, the clairvoyance is indeed made for the military, and it can also be used for astronomy, geography, or navigation." Li Jie was very satisfied with Zhu Yuanzhang's performance, the other party was born in the army, and he was originally a very good commander, so he could definitely think of the use of telescopes in military affairs.

"Father, can you let your sons see this clairvoyance as well?" Zhu Biao, who was itching, finally couldn't help but ask at this time, he was too curious about this clairvoyance.

Zhu Yuanzhang was also very happy at this time, and handed over the clairvoyance to Zhu Biao, but when Zhu Biao personally experienced the magic of clairvoyance, he was also full of praise for Li Jie.

"Li Aiqing, the reward for the flintlock pistol last time has not yet been released, and you actually offered such a treasure, which makes me not even know how to reward you!" Zhu Yuanzhang laughed and sat down behind the bookcase, and even asked people to give Li Jie a seat, and even changed his mouth to call Li Jie Aiqing, which is very rare in the court.

"Your Majesty's words are serious, these are what ministers should do!" Li Jie also 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 with great interest, the first gift is a telescope, and the second one is definitely not worse than the first.

Zhu Yuanzhang also came to his senses when he heard this, and immediately asked people to take the second box, saying that it was a box, in fact, this is a two-foot square box, which is much larger than the box with a telescope, but the box is not heavy, and when the box was opened, Zhu Yuanzhang and Zhu Biao, father and son, were all dumbfounded when they saw the things in the box, and it was another thing they didn't know at all.

The eunuch took out the contents of the box and put it on the bookcase, only to see that this thing was a large wooden ball, with protrusions at both ends, connected to the shelf, and could also be rolled, and under the shelf, there was a round support, so that the thing could be placed firmly on the bookcase.

"What is this ball?" Zhu Yuanzhang looked at this strange wooden ball and asked with a puzzled expression, he found that this ball seemed to be carved with some complex patterns, it seemed to be like a map, but why was it drawn on a ball?

"Your Majesty, the name of this ball is the globe, which depicts all the land and seas in the world, and our Ming Dynasty is here!" Li Jie stepped forward as he spoke, and then found the location of Daming and pointed it out to Zhu Yuanzhang.

This globe was created by Li Jie let the craftsmen of the Ordnance Bureau, and then he personally carved the global map on it, of course, he only carved it by 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 incorrect, if someone sails according to the map above, I am afraid that I don't even know how to die.

"Wait! Do you mean to say that the earth we live on is a ball? Zhu Yuanzhang's eyes widened when he heard this, with an expression of disbelief, although he was one of the most outstanding emperors in history, he was also the emperor with the lowest background, and his knowledge reserve was poor, especially in astronomy and geography.

"This can't be the legendary Hun Tian theory, right?" In contrast, Zhu Biao, the crown prince, is stronger than Zhu Yuanzhang, after all, he has received an orthodox royal education and is no stranger to astronomy and geography.

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

"The sky is like a chicken, the celestial body is round like a projectile, and the earth is like a chicken." Li Jie stepped forward with a smile and explained, and 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, it is a sphere, and all living beings in the world live on this sphere!" ”

"This ...... How is this possible? Zhu Yuanzhang heard Li Jie's explanation but looked unconvinced, if it wasn't for the telescope that Li Jie had presented before, I'm afraid he would have driven Li Jie out as a liar.

"I also understand this, but if we live on the same ball, if we are head-up, won't the people on the other side be head-down, and they won't fall?" Zhu Biao also immediately asked at this time, this is also a problem that cannot be explained by the ancient armillary theory.

"His Royal Highness the Crown Prince's question is actually very easy to answer, let me show His Majesty and the Crown Prince about it!" Li Jie was full of confidence, and it seemed that he had expected someone to ask such a question.

I saw Li Jie pick up the globe, and then walked quickly to the door, Zhu Yuanzhang and his son also followed curiously, only to see that after Li Jie came to the door, he actually rolled the globe on the ground a few times, and then took it back and showed the two: "Your Majesty, please see, what is more on this globe?" ”

"Dust?" Zhu Yuanzhang looked at the dirty globe in front of him and immediately replied, Li Jie rolled on the ground a few times, it was strange that it was not dusty, but it was spotless in the warm pavilion, no wonder he wanted to run outside.

"Yes, it's dust, the earth we live on is too big, we are like a grain of dust on this globe to the earth, even if you turn the globe, the dust will not fall by itself!" Li Jie smiled and explained that he wanted to use gravity to explain, but Lao Zhu's father and son definitely didn't understand, so it was easier for them to accept this example to explain.

"It makes sense, in this way, Hun Tian said that it is very reasonable!" Zhu Biao also showed a thoughtful expression when he heard this.

Zhu Yuanzhang also showed a contemplative look, and after a long while, he suddenly opened his mouth and ordered: "Xuanqin Heavenly Prison!" ”

Li Jie heard that Zhu Yuanzhang was going to summon Qin Tianjian, and immediately smiled bitterly, it seems that this Lao Zhu's suspicion has been committed again, but this is also normal, after all, this has driven out of Lao Zhu's understanding, of course, we must listen to the opinions of professionals.
