The next day, Chao Yong came to the palace with a telescope.

The book of mathematics took ten days to finish, because the content written by Chao Yong is only some introductory knowledge, and the second is that ancient arithmetic is also very developed, Chao Yong does not have much new things to say, and the teachers and students in Taixue are all talented people, so the teaching process is also very fast.

Chao Yong also selected a few outstanding people and asked them and Qin Hui to continue teaching mathematics in Taixue.

Chao Gai has made a will, and in the future, mathematics will be added to the assessment of Taixue, and the imperial examination will wait until mathematics is popularized throughout the world.

However, the promotion of Taixue depends on the usual grades, and the upper class can be directly awarded, so Taixue students are still very enthusiastic about learning mathematics.

When Chao Yong arrived at the palace, the early dynasty had already dispersed, which was also deliberately avoided by Chao Yong. Most of the things dealt with by the early dynasty were local political affairs, although they could not be said to be trivial, but Chao Yong was not interested in those things, so he generally did not go to the early dynasty.

He hates others grabbing power, but he definitely doesn't covet power. If he is made an emperor, all these things must be handed over to the ministers, and only military affairs will be taken care of, and he will be a carefree emperor in peacetime.

Chao Gai also put a lot of power, but there were still a lot of twists and turns handed to him, and he had been watching the twists and turns since he dispersed the early dynasty.

"See Father."

Chao Gai heard Chao Yong's salute, so he put down his hand, saw Chao Yong holding a box in his hand, and said with a smile: "What did you do again?" The silver mirror sent yesterday was very much liked by your mother, so I will send a few more to your mother. ”

Chao Yong smiled: "Since the queen mother likes it, I will ask people to make a few more and send them." There are magnifying glasses and telescopes, magnifying glasses can make things look bigger, and telescopes can make people see things in the distance. ”

As he spoke, he walked over to Chao Gai, took out a gold-handled magnifying glass, and placed it on top of the fold. The small characters on the fold immediately became much larger.

Chao Gai nodded and said, "This magnifying glass can allow people with poor eyesight to read." ”

Chao Yong smiled: "I have special glasses, but my father's eyesight is very good, so I didn't bring them." A magnifying glass is not of much use, this telescope is a good thing. ”

As he spoke, he picked up the monoculars and said, "Father, just look out from here." ”

Chao Gai took the telescope and put it on his eye.

The pillar in the distance suddenly appeared in front of him, as if it had collided, and Chao Gai subconsciously flashed back.

When I saw that the pillar was still there, I realized that it was the telescope that was doing the trick. Curious, he looked at it again, and the pillar in the distance seemed to be many times larger, and it was right in front of him, and he could see it very clearly.

I couldn't help but wonder: "How far can I see?" ”

Chao Yong smiled: "It's hard to say this, look at how clearly my father has to see it." Let's go outside and try it, and my father will know. ”

"Okay."

Out of the vertical arch hall, Chao Gai looked at it for a while, then put down the binoculars and praised: "Good thing." I think this can also be used in military affairs. ”

Chao Yong nodded and said, "With the telescope, it will be easier for the sentry to be sentry, and it will be difficult to ambush our army." With the cooperation of the telescope and the spacecraft, there should be no problem in seeing for ten miles. ”

"Good stuff. It is really a divine weapon, and it must not fall into the hands of the enemy. ”

Chao Yong hurriedly said: "Actually, this thing is very easy to do, as long as you learn the physics I wrote, you can know how to do this telescope." I can't hide it from anyone. I want to open a mirror shop, selling glasses, magnifying glasses, and telescopes, and add a fortune to the imperial court. ”

Chao Gai handed the telescope to the eunuch who was waiting next to him. "Put it away." ”

The eunuch also saw that Chao Gai had something to say to the prince, so he hurriedly took the telescope and retreated.

Chao Gai frowned and said, "Physics is so powerful, you can make spaceships and telescopes." So how can physics be taught to people, and now physics is theology. There are spaceships ahead, and now there are telescopes, not theology or anything. Such a powerful skill can only be passed on to a son, not a daughter, let alone an outsider. ”

Chao Yong also knew that physics was still a bit of a peerless taste for this era, although many sages had discovered some physical knowledge, such as Mozi, who had mastered some knowledge of optics and discovered the principles of convex lenses, concave lenses, and small hole imaging, but did not elaborate in detail in the work, but simply recorded it. The use of beads for fire and the use of ice for fire are also recorded in "Guanzi" and "Huainan Wanbishu".

These sages may have thought that these things were very simple, and as long as they left a few words, future generations would know about them, but without detailed descriptions, a lot of knowledge was lost, and it may take hundreds or even thousands of years for someone to find out this knowledge again.

Of course, the application of telescopes to optics is more than the use of ice for fire, at least no one has ever made a telescope before.

However, Chao Yong didn't want to hide these "unique learnings", as soon as he hid, it is likely that the descendants of future generations will always hide them, and when other nations begin to move towards science, they will really become self-cherished. The physics he wrote about was not something profound, at best it was an introductory thing, and once a nation began to study it, these things would be all over the streets. And China is likely to still follow that old path, with poetry, books and etiquette handed down for thousands of years, and then it can be said that science knocked on the door by guns.

Chao Yong has the confidence to sweep the world, but this does not guarantee that the Han people will always stand on top of the world. There is no empire on which the sun never sets, and once Europe breaks through the darkness of religion and accepts the baptism of science, history may repeat itself. Therefore, Chao Yong wants to let science sprout in China and take the lead in accepting the baptism of science. In this way, even if you can't dominate the world in the future, you won't be beaten because you fall behind.

What he wants to do is to promote mathematics and physics under his absolute force, so that people can learn to understand the world objectively, instead of blaming God for what they don't understand.

Of course, we do not lack ancestors who objectively understand the world, but just as the European sages were persecuted by religion, our ancestors who really knew the world were often killed by various forces, in order to protect the emperor's country, in order to maintain the interests of some people, and even in order to maintain etiquette, a lot of knowledge was lost in the long river of history.

However, Chao Yong couldn't talk to Chao Gai about these things, so he could only say: "It's actually difficult for us to keep it secret, as long as the spaceship is used too much, everyone will find that the spaceship only has a pile of fire." Coupled with the example of Kong Ming lanterns, it is easy for people to imitate spaceships. It's just that they don't know the principle of the spaceship, but that doesn't affect them from making the spaceship. Besides, what if this telescope is given to the enemy? My beam will soon be sitting on the world. Millions of soldiers and horses can be easily gathered, so why play tricks with them, you can defeat them with a dignified array. In fact, the most powerful weapons of my girders are gunpowder and the guns that are being developed, and as long as we have them, we can defeat all enemies. ”

Chao Gai thought for a moment and said, "Is there any benefit for you to teach physics to people in the world?" ”

"It can make people in the world understand the world more objectively, guide people in the world to explore all things in the world, enrich this knowledge, and then create more powerful things."

Chao Gai couldn't help but wonder: "What other powerful things can be made?" ”

Chao Yong smiled: "A spaceship that can fly to the moon, a submarine that can dive underwater." A car that is faster than Maxima. ”

Chao Gai was dumbfounded and said, "Can you fly to the moon?" ”

"Yes, but that kind of spaceship requires very advanced science, and I am afraid that it will not be possible to build it in hundreds of years."

Chao Gai couldn't make it for hundreds of years, and couldn't help but say disappointedly: "Then we can't see the moon." ”

Chao Yong naturally knew that what Chao Gai said was to see clearly, not the small moon hanging in the sky every night, thought about it, and said: "If you go back, you can let people try to make an astronomical telescope, and you can see the appearance of the moon clearly." In fact, there is no Moon Palace and Guishu at all, let alone Chang'e and Wu Gang. It's a potholed planet. ”

Chao Gai said in disbelief: "There is nothing on the moon? ”

Chao Yong nodded and said, "Nothing." ”

Chao Gai would not doubt Chao Yong's words, but this fact still made him a little difficult to accept.

After half a sound, he said: "So, the legend of the moon is all fake." ”

Chao Yong said helplessly: "Maybe those stories are just stories for children." It's been rumored that everyone is taking it seriously. ”

Chao Gai couldn't agree with Chao Yong's words, but he couldn't find a better explanation, and said, "Go back and have someone make an astronomical telescope and send it." ”

Chao Yong nodded and said, "The first astronomical telescope must be sent to the palace, and I would like to ask my father to withdraw the will to ban astronomy as well." In fact, the tengu eating the moon and the broom star are all special astronomical phenomena that do not indicate anything at all. The theory of celestial and human induction. While it's not complete nonsense, it's basically not credible. In the future, if someone uses the astrological signs to interfere in politics, it can all be regarded as a fallacy to confuse the public. ”

Chao Gai was stunned, and suddenly said, "Then what about the stars you said descended to earth?" ”

Chao Yong also froze slightly, and immediately said: "The stars I am talking about are not visible to people, just like there are gods in the sky, but they will never be known, let alone worshiped by humans." In their eyes, humans are nothing more than ants, so what is the use of them enjoying our incense? Just like we don't want ants to worship us. ”

Fortunately, when Chao Yong wanted to destroy the sect, he thought of an explanation for himself, otherwise he would really have been asked. If Chao Gai knew that Chao Yong had been lying to him, he would inevitably have to serve the family law. Thinking of the family law that Chao Yong received when he was a teenager, he shuddered a little.

Chao Gai thought for a while and said, "What you said is also true, why do we need ants to worship." ”

Chao Yong continued to instill his atheism: "Father, you think, there have been people in the past who have said that Zi Weixing has descended to earth or something, but when did Zi Weixing disappear?" It can be seen that there are really star kings, and I don't think they are those stars in the sky. On the other hand, what is the reason for interfering in the government with those stars? Most of the doctrine of celestial and human induction has a role to restrain the emperor. The changes in the heavens, floods and droughts in the world are all natural phenomena, and they have nothing to do with the emperor's conduct at all.

Just like this year, my father ascended the throne and exempted the world from agricultural taxes and forced labor, which can be said to be benevolent government, and all roads in the world are still floods, droughts and locust plagues. If it weren't for the new dynasty and the steel knife in our hands had not been returned to the sheath, I am afraid that many people would write to say that the father was immoral, and even asked the father to issue an edict. ”

Chao Gai said with a smile: "There are really people who say that my Liang is too heavy and wants me to amnesty the world." ”

Chao Yong didn't expect that Da Liang was still killing corrupt officials everywhere, so someone dared to jump out, and couldn't help asking: "Didn't my father deal with him?" ”

Chao Gai shook his head and said: "Previously, we set the law that no one will be punished for words, and there are only some upright people in the court, and if they are punished for this, I am afraid that they will become people who only know flattery." ”

Chao Yong was curious: "Then did you impeach me?" ”

Chao Gai shook his head and said: "Only when you killed Li Qianshun privately, Uncle Zhang took the lead in impeaching you, and a few people seconded it, and no one else impeached you." Thou hast slaughtered, and seldom retreated. They're afraid they're all worried about your revenge afterwards. Of course, this is also related to the fact that there are almost no really upright people in Zhao Ji's court, and many courtiers who are not afraid of power have been relegated to various places by Zhao Ji. After Zhao Zisong went to Jiangnan, he helped Zhao Ziwei invite a group of officials who had previously been managed and belittled by Zhao Ji. They are the real upright people, and the people in the court now are just people who see the wind and steer the rudder. ”

Chao Yong said with a smile: "After all, the people who are really not afraid of the powerful are a minority, and whether the majority of people are upright or tend to be inflammatory, in fact, it is decided by the emperor, what kind of people the emperor likes, what kind of people they are, and there are always a few people who dare to be out of place." Zhao Ji, who tends to be angry in the middle of the court, has now become upright people, right? ”

Chao Gai nodded and said, "You're right, I've looked through a lot of people's previous recitals. Many people used to be either attached to the trend, or simply rarely discussed politics, but now they are quite insightful, and when they encounter political affairs with different opinions, they dare to argue with Wu Yong and others, and they are like two people before. ”

"For us, these people are much easier to use than Li Gang and his ilk. If we overthrow the Song Dynasty, Li Gang and his ilk will not be of use to us, but these people can be of our use. Their talents may be higher than Li Gang, but their character is not as good as Li Gang. ”

Chao Gai nodded and said: "These people are villains after all, and they may harm the world again at any time, so they can't be of great use." ”

Chao Yong shook his head and said, "Erchen doesn't think so. Whether they can be upright men and gentlemen for a lifetime is completely in the emperor. As long as the emperor's preferences remain the same, for the sake of their official position, they will not change. Just like Cai Jing. When Zhao Ji first became the emperor, Cai Jing was also a capable minister, if Zhao Ji could always work hard. Then Cai Jing may be able to live for a hundred years. It was only later that Zhao Ji was greedy for pleasure, and Cai Jing became only known about looting the people for Zhao Ji's pleasure for his position. ”

Chao Gai thought for a while and said with a smile: "What you said is not unreasonable, as long as they have merit, I can't help but give them a promotion." As long as they don't do anything wrong, I can only watch them rise to a high position step by step. But I'm afraid I'm going to eat people in the future, and my Liang is all the villains of the Song Dynasty. ”

Chao Yong said with a smile: "No one will think that the emperor will not use people, Wei Zheng of the Tang Dynasty was first in the Wagang army, and later became Li Jiancheng's staff, Li Shimin killed Li Jiancheng, and he became Li Shimin's official." There is no difference between him and Lu Bu, but Lu Bu did not succeed in the end, but Wei Zheng made great contributions to the rule of Zhenguan, so he became a minister through the ages, and Li Shimin also gained a reputation for knowing people and making good use of them.

The more Zhao Ji and these people in the court govern the world, the reputation of his father will be agreed, and of course, Zhao Ji's reputation will be worse.

The people who have done a lot of evil in Zhao Ji's court have already been punished, and although most of the remaining people are people who tend to be inflammatory, they are just wise people who protect themselves or are greedy for wealth and wealth, and they have not done anything evil. It is not unreasonable for the father to appoint them. There are a few people in the world who are not greedy for wealth and wealth, if those who read are not for the Golden House and Yan Ruyu, how many people are willing to study hard every day, and they also burn their eyes, and the glasses are mainly sold to those who read. ”

Chao Gai is magnanimous, but his temperament is also jealous and hateful, and he has always been obsessed with the appointment of villains in the Song Dynasty. chatted with Chao Yong for a while, and finally eliminated the mustard in his heart.

These words, he is not good to say to Wu Yong and others, especially after arriving in Tokyo, Wu Yong and Zhang Shuye have been asking Chao Gai for power, and Chao Gai and Wu Yong are inevitably estranged.

Hearing Chao Yong make fun of readers, he couldn't help but laugh: "You seem to have a lot of opinions about readers." I was born in the rivers and lakes, and I also like martial arts rather than literature, but I don't have such prejudice as you. We rely on the Liangshan brothers to fight the world, but we also rely on these scholars to govern the world. ”

Chao Yong shook his head and said: "I don't have an opinion on readers, but on those who read dead books and feel that everything is inferior, only those who read high-quality books." They didn't see them invent gunpowder, spaceships, or telescopes when they read books, but they only knew how to recite poems and lyrics every day, and study those complicated etiquette. Speaking of which, recently, they can neither resist the Liao people nor educate the Liao people with books, and what is even more shameful is that they have no backbone. Externally, the people's hard-earned money is used to buy peace from the Liao State, and internally, the people's hard-earned money is squandered extravagantly. The people couldn't eat enough for three meals, but the sergeant doctor couldn't get tired of eating and eating. Of course, I'm not completely against reading people, otherwise I wouldn't have gone too far to give lectures. ”

Chao Gai heard Chao Yong say this, and he was also relieved.

Chao Yong remembered his previous words again, and said: "Which loyal ministers and good generals have been invited by the Southern Song Dynasty? ”

Chao Gai said: "The most famous is Jiang You, Zong Ze two, these two are upright, Jiang You was an official to the three products, served as the Ministry of War, the Ministry of Industry, the Ministry of Officials, although the official position is not high, but it is widely seen, the palace test will be sprinkled with more than 10,000 words of needles and needles, for the official is not afraid of the powerful, love the people like a son. Later, he was dismissed because of his opposition to Lianjin's extermination of Liao, and was accused of contempt for Taoism, and was put in charge of Runzhou. After Zhao Zisong went down to the south of the Yangtze River, he invited two people from Runzhou, and then appointed some high-profile officials one after another. During this period of time, the Southern Song Dynasty also gathered some people's hearts. ”

Chao Yong was naturally no stranger to Zong Ze's name, and said with a smile: "They invited these people to come just to make us wedding dresses." If there are no elite soldiers and good generals, even the loyal ministers of the ages have gathered in the Southern Song Dynasty, and what can they do to resist our army. (To be continued......)
