"I see it, I see it." Zhong Guiyi held up a long yellow copper pipe and stood on the attic of the outer courtyard of Zhaodefang, jumping up and down.
She looked excited and bouncing around, and there were several children around her, both boys and girls.
With a sound of wow, Little Taozi came down from the railing, carrying the long tube behind her back, looking like a good girl.
Yang Tianai asked strangely: "Taotao, what's wrong, what's wrong, what did you see?"
Zhong Guiyi gave her the long tube in his hand, pointed to the front and said, "Nuo, see for yourself."
Yang Tianai looked curiously and saw the scenery in the distance before her eyes. She saw her beloved adoptive father rushing here with several students behind his back.
Yang Tianci, who was basking in the sun, lazily asked: "Sister, what's wrong?"
"My godfather is back." Yang Tian said with warmth in his heart and a somewhat awkward tone.
Yang Tianci was immediately excited. He and a group of miscellaneous scholars from the outer courtyard used the guidance of his adoptive father to make this telescope.
In fact, the Han people have been playing with lenses for thousands of years. In "Huainan Wanbi Shu", there is even a method of processing ice into spherical lenses. Zhang Heng of the Eastern Han Dynasty also used lenses to observe the moon. Zhao Xihu of the Song Dynasty once mentioned it in "Dongtian Qinglu"
It’s just glasses, but colored glaze was too expensive by the Arabs, so glasses didn’t become popular in the Northern Song Dynasty.
With Yang Lin explaining the principles of combination use and distinguishing the differences between the lenses used in eyepieces and objective lenses, and with his Zhaodefang having a large supply of transparent crystals, several miscellaneous scientists, together with Yang Tianci, finally made it after many experiments.
The world's first "telescope" was produced.
Now that his adoptive father is back, he is just in time to ask for a reward. Even if he doesn't give anything, having his adoptive father praise him is what Yang Tianci has longed for since he was a child.
As soon as Yang Tianci ran away, several children followed him and ran downstairs.
At the entrance of the outer courtyard, Yang Lin led two students, namely Yu Wenxuzhong and Ma Kuo.
"I have already recommended you two as envoys to Daliao in front of His Majesty."
The two people looked at each other and saw the excitement in each other's eyes. Yang Lin paused, found a stone bench in the courtyard, sat down and said, "What do you think of the Battle of Jin and Liao?"
When he heard that his mentor was going to test him, Ma Kuo plucked up the courage and said first: "Students think that the powerful tribes of the grasslands have always taken advantage of the situation. In the Han Dynasty, they were the Huns; in the Tang Dynasty, they were the Turks; in the late Tang Dynasty, they are the Khitans; now the Jurchens
His momentum is like a rainbow, and he will surely be able to defeat the Khitan in one fell swoop.
In this way, we, the Song Dynasty, should form an alliance with the Jin people, send troops to recover the land of Youyan, and avoid the shame of Taizong's Northern Expedition."
His voice was loud and his face was red. He was obviously very ambitious and wanted to do something big.
Yang Lin was not in a hurry to deny him and asked Yu Wenxuzhong: "Shutong, what do you think?"
Yu Wenxuzhong was not in a hurry to answer, but instead patted his senior brother on the shoulder and said: "Zichong, although what you said makes sense, when I think about it carefully, it is also quite risky.
The Jurchen was so ferocious and barbaric that many innocent people were killed by the Huanglong Mansion, and all ethnic groups were harmed by it. It was obvious that the barbaric spirit was still lingering and the animal nature overcame the human nature.
The Khitans are different. Although they are also barbarians, they already have laws, etiquette, and integrity.
If we work with the Jurchens to defeat the Khitan, we will only have the land of Youyan, but the Jurchens will easily swallow up the entire Liao.
When the time comes, how could they not want to go south and get involved in this beautiful country?"
Ma Kuo's eyes widened and he was about to refute, but Yang Lin pressed his hand to dissuade him.
Yu Wenxuzhong turned to Yang Lin and said: "Teacher, my student thinks that for the Song Dynasty, it is better to protect the mediocre and declining Liao Dynasty than to support the powerful Jin Dynasty.
The Liao people have declined to this point. If we can stop the Jurchens for us, when the time comes, the Song Dynasty will take Youyan as if it were a treasure.
If the Jurchens accidentally capture the entire Khitan, it will be difficult for us to return to Youyan."
Yang Lin used his eyes to signal Ma Kuo to continue speaking. He raised his trademark loud voice and said: "Teacher, this opportunity must not be missed before it comes back. Instead of looking forward and backward, fearing the rise of the Jurchens, it is better to take this opportunity to get Youyan back first.
.Anyway, no matter what kind of alien race is outside the pass, they will have to fight with us. If we get You Yan back, we will use our troops to block it. The water will come and the earth will cover it. No matter who comes, we will decide the winner."
Yang Lin carefully considered the conversation between the two students in front of him and tasted it.
Yu Wenxuzhong had a long-term vision, was good at planning in advance, saw deeply, was thoughtful, and had good plans. No wonder he was able to become the national advisor of the Jin Kingdom in later generations, and he almost stole Qin Zong back and restored the north.
Ma Kuo, on the other hand, was good at seizing the opportunities in front of him. He was a talented general, but he could not hold a position like prime minister.
After making up his mind, Yang Lin smiled and said: "Your Majesty and I are leaning towards Shu Tong's advice. Zichong, you will be the deputy envoy when you go this time. Anyone who listens to Shu Tong more."
Although Ma Kuo was not convinced, he still wanted to listen to his mentor's words. The two of them clasped their fists together and said yes.
At this time, a group of children ran over. Before Yang Tianci could say anything, his sister grabbed the telescope from behind, took it out like a treasure in front of his adoptive father, and explained it for a while.
In her opinion, the man in front of her was handsome and handsome. When he smiled at her, it was as if a spiritual light flew out and covered her eyes. She was so excited that she was so dizzy that she didn't know where he was.
Yang Lin looked at the cute little girl and couldn't help but touch her head. Yang Tianai's body was half electric, and his body suddenly became half numb.
Seeing that she was his own sister, Yang Tianci didn't care about her taking credit, so he smiled and added afterward, speaking eloquently.
Yang Lin picked it up and looked into the distance. There were still some flaws, but he could already see very far.
He chuckled, handed it to Ma Kuo, and said: "My teacher often tells you that all knowledge in the world is knowledge, and everything in the world contains infinite natural knowledge. Look, this telescope is the product of Ci'er and the others.
of."
Both of them tried it and were amazed, and they became more convinced that Yang Xue was the truth.
If one can see things thousands of miles away, then becoming a saint is not impossible.
Yang Lin looked at his two beloved disciples and said with a smile: "Okay, what you have to consider now is Jin Liao. Go back and clean up immediately. I will select a few capable officials for you in the court to follow you.
Go to Beijing.
When you arrive in Khitan, you should not act on your own initiative, but put state affairs first.
You must be tough in public affairs, and do not lose the dignity of the Song Dynasty. In private, you must be humble and courteous, give a lot of gifts, bribe a lot, and bribe as many Khitan officials as possible. It is best to get along with the Khitan nobles, so you can rest assured that you will have plenty of money to teach you.
All accounts can be reimbursed for eating, drinking and having fun in Shangjing.
Only in this way, if we need you to do anything in the court, will there be someone available and you will know what to do."
Ma Kuo felt a little uncomfortable, but Yu Wenxuzhong remembered everything in his heart, and the two of them said goodbye and left together.
