I learned skills in a different world

As for the telescope, it was not difficult for Shen Fangshi to make a "telescope" using a glass concave lens.

Just making a telescope requires more transparent and more uniform glass. If you want to make glass clearer, you must choose high-quality quartz sand as raw material, add various auxiliary materials, and strictly control the temperature and stirring to make the glass liquid highly uniform.

After the glass liquid is poured into the mold and the finished product is produced, it needs to be polished delicately. The polishing is divided into three steps: rough grinding, fine grinding, and polishing. Shen Fangshi only knows how to polish wood for the time being. Due to various reasons, he can't find glass that meets the standard.

Fortunately, there are already skilled craftsmen in this field. Although there is no glass, there is still crystal. Shen Fangshi asked these craftsmen to teach him how to grind and polish it.

After struggling for a long time, it was finally completed.

Shen Fangshi originally planned to make a few more, but the lenses needed to be ground very finely, and it took a lot of time to make one. He was about to leave for the capital, and he didn't have time, so he only succeeded in making two.

One is going to be given to Emperor Wei, and the other is going to be given to Chu Kui. The telescope can be used to conduct terrain survey and enemy situation observation. Although there is no war to fight for the time being, it is good to have one just in case.

And he was prepared to use the telescope in conjunction with firearms.

Although today's fire cannons have sights, their shooting is not particularly accurate. If a "telescope" is placed on the cannon's cannon, its accuracy will definitely be improved.

However, that side mission 2 was a bit strange. The previous missions never required him to personally inspect it. This mission obviously asked him to follow Chu Kui and the others to Beijing.

In a normal march, the march from Yucheng Pass to the capital will take about twenty-eight days, which includes sleeping time, meal time, rest time, etc. Moreover, Chu Kui will bring 6,000 elite troops to Beijing this time. Walking and maintaining formation will definitely be much slower than riding fast.

In fact, Shen Fangshi could choose not to do this side mission, but in the end he decided to go there to see the purpose of the system issuing this mission and what "surprises" there would be in the capital.

Although the carriage he made himself looks ordinary, it actually has something else going on.

The materials of the carriage are exquisite, and the wheels of the carriage are all made of iron birch. It is not only of high quality and wear-resistant, but also cannot be penetrated by ordinary swords, guns and arrows. A shock-absorbing device was also installed during the sinking process. There are windows in the front and on the left and right sides of the rear room of the carriage. The windows can be opened and closed, which is conducive to ventilation and lighting, and is also conducive to sealing.

The interior is exquisitely decorated and made with precision workmanship, and can accommodate people on three sides. There are also tables, chairs, beds, etc., with extra-thick mattresses. There are also organs inside for placing food, weapons and other things.

Shen Fangshi was sitting in a carriage along the way. Although his cultivation was good enough to build a foundation, it was not convenient to ride in a carriage. Therefore, he decided to find a suitable time to break through in the space world after settling down in the capital.

However, since going to the capital, Chu Kui has become a little strange, often hesitating to speak.

Finally, on the way to the capital, Chu Kui suddenly got into the carriage.

Shen Fangshi looked at him with a half-smile, "Why, you finally couldn't help it anymore?"

Chu Kui's face was a little serious and his body was a little tense.

Seeing that Chu Kui seemed a little nervous, Shen Fangshi's voice became softer and said, "Tell me, what do you want from me?"

"After all these years, what would you think if someone hid something from you?" Chu Kui said hesitantly.

He never knew he could be so timid. In the ten years since Yucheng passed, he had almost forgotten his identity as a prince, and he had forgotten to tell Jing Nian. It was not until he conquered Hu Mang and was recalled from the capital that he realized that he was more than just Yucheng. The governor of the pass was not only Chu Kui, the general of Yucheng Pass, but also Xiahou Kui, the seventh prince of the Wei Dynasty and personally named King Yu by the emperor.

He didn't dare to tell Lin Jingnian, not because he didn't trust him, but because he was afraid that he would ignore him and be angry that he had kept his identity hidden.

Shen Fangshi raised his eyebrows and said directly: "Do you want to tell me your true identity?"

Chu Kui's body stiffened. He had noticed it for a long time, and he was relieved immediately. He was so smart, how could he not guess it.

So he no longer hesitated and said directly: "I am actually the prince of the Wei Dynasty, Xingqi. Ten years ago, I was canonized as King Yu for my meritorious service in guarding the customs. My surname is actually Xiahou, but I changed it to Chu because I don't want to reveal my identity. Chu is actually my mother’s surname.”

Shen Fangshi thought to himself, Xiahou is the national surname, no wonder many people have not discovered Chu Kui's identity.

Lin Xiaotao likes to inquire about some gossip. Over the years, he has followed Lin Xiaotao and heard about some things in the capital. For example, although the mother of the seventh prince was of humble origin, she was a palace maid, but she was so beautiful that she could be called the most beautiful woman in the Wei Dynasty. But Tian was jealous of the beauty, and she passed away when the seventh prince was three years old.

Thinking of this, Shen Fangshi looked at Chu Kui, but in the end he said nothing. Since the matter was over, he would only make people sad if he mentioned it again.

But Chu Kui seemed to have seen through his thoughts, and smiled slightly with relief: "I was still young when my concubine passed away, and I didn't have a deep impression of my concubine. The only impression I had was that my concubine was always a gentle woman. .”

Shen Fangshi said softly: "Your mother-in-law must be very good."

Chu Kui nodded. What he didn't say was how difficult it would be for a three-year-old prince to live in the palace after losing his mother.

At that time, his mother's concubine passed away, and his father soon had a new favorite concubine, who didn't pay much attention to him. Moreover, his mother's concubine was from a palace background. Although he was promoted to the concubine position through Emperor Wei, it was like a castle in the air. People who had offended his mother and concubine because of his previous favor began to make trouble for him, and his life in the palace became increasingly difficult. However, he was the prince after all, and others did not dare to go too far. Chu Kui worked hard to practice martial arts in the palace. He only waits to leave the palace and build a mansion after he reaches adulthood.

It wasn't until he was fifteen years old that Hu Mang broke through Yucheng Pass and marched all the way into Huizhou. He was about to advance into the capital area. As he prepares to abandon the city and flee, his normally self-proclaimed royal brothers are now like ants on a hot pot, and his noble and conceited concubines are also pale in appearance.

Chu Kui felt ironic, but when he saw that the people were in dire straits, he stopped again, and finally asked Emperor Wei for orders to lead troops to resist Hu Mang.

Emperor Wei had given up hope and just wanted to escape. At this time, Chu Kui's sending troops could delay him for some time, so he casually agreed and personally named his long-forgotten son King Yu.

Maybe Emperor Wei didn't expect that his son, who he didn't value, could repel Hu Mang all the way and successfully forced Hu Mang back outside the Yucheng Pass.

Shen Fangshi noticed that Chu Kui's expression was a bit cold and stern, "Then why did you hide your identity?"

This doesn't seem to be needed.

"It's Father."

Hearing what Chu Kui said, he felt something clear in his heart. Emperor Wei had to give Chu Kui real power because Chu Kui had defeated Hu Mang and needed him to guard the border. However, he was worried that his great achievements would shock the emperor, especially since Chu Kui was still a prince. That's why Chu Kui was asked not to reveal his identity in order to avoid gaining greater prestige.
