With qualified lenses, the work of making telescopes has been basically completed.

The next job is to design the size and length of the telescope based on the focal length of several lenses.

The focal length of the lens is relatively simple. I have been tested repeatedly with ice-made convex lenses. As long as the converging light spots are completely on the ground on sunny day, the distance between the focus point and the lens is the focal length. These four convex lenses are the size and thickness confirmed by Chen Xu after countless observations of ice lenses. They were carefully measured with a caliper. Although there will definitely be some slight deviation when making the mold, this is just the most primitive telescope. You can see some things that are invisible to the naked eye in the distance. As for what you want to see clearly, it is definitely not possible, and you don’t need to see so clearly.

Therefore, after returning home, Chen Xu immediately asked someone to lay a thick mattress on the warm kang, and asked the four little maids to sit on it and start to help carefully polish the lens. This is an extremely patient and meticulous job, so it is more reassuring for women to do it.

Chen Xu took out the telescope prototype drawings he designed previously and began to make final modifications and detailed designs.

Just as Chen Xu was concentrating on his work, Yu Wuya came in with a plate of hot braised sheep hooves and braised duck necks with excitement.

Smelling the strong fragrance, Chen Xu felt instantly hungry, so he threw the pen off the kang, washed his hands and picked up a sheep hoof and started to chew it. At the same time, he smiled and said, "It seems that the chef got up early today, and he even bought sheep hoofs. He hasn't eaten it for several days!"

Several little maids sitting on the kang polishing lenses couldn't help but lower their heads and sneer, while secretly looking at a plate of braised sheep's hooves and swallowing secretly.

"I reward you for one!" Yu Wuya said while chewing.

"Thank you, Mr. Yu!" The four little maids immediately put down their things happily, jumped off the kang, each of them took a sheep's hooves, and sat in a row on the edge of the kang, barefoot, while shaking them while eating.

"What did you laugh just now?" Chen Xu asked curiously.

"I dare not say it!" Several young maids quickly buried their heads in their chests.

"Is there anything I dare not say? This was what I cut back from a rich family's sheep pen last night!" Yu Wuya shrugged indifferently.

Chen Xu was immediately amazed and laughed.

Just after the disaster, he cured dozens of chickens and ducks in Su Neishi's mansion, and then went to another sheep pen. Yesterday, a group of people talked about a variety of braised products that Yu Wuya had not eaten before. If this continues, the whole of Xianyang will be worried about his disaster in a few days.

Sure enough, Yu Wuya finished gnawing a sheep's hoof and said, "When it's dark tonight, I'll go and cut a few pigs' ears back!"

"Okay, okay~ Mr. Yu is the best. We can eat pig ears again tomorrow!" Several little maids laughed excitedly.

"Hehe, that's natural. In the future, tell Mr. Yu what you want to eat. I can get all the tigers raised by the emperor for you. If you want to eat your ears, eat your ears, and eat your tails..." Yu Wuya proudly picked up the second sheep hoof and ate it.

Chen Xu sighed and began to bite the sheep's feet in his hand with concentration.

...

In the next few days, the rich braised aroma of Qinghe Hou Mansion drifted around every day, and could be smelled across the street, which caused countless people passing by to drool and look envious and jealous.

At the same time, a very unsettling news began to spread in Xianyang.

A mysterious thief appeared in the city. He was very skilled in martial arts and had no trace of coming and going. He specialized in stealing lamb legs and pig ears, and also stealing duck necks and chicken legs and duck feet.

Many wealthy families have suffered from chickens, ducks, pigs and sheep.

The most cruel one was that last night, the Dianke Mansion was visited by mysterious thieves. More than 20 sheep and seven or eight pigs were cut off, their feet were cut off, and their ears were cut off. In the morning, the slaves opened the pigpen and sheep pen and saw the livestock lying all over the ground. They were so scared that they fainted.

"Your Majesty, you must make the decision for the old minister!" At the beginning of the morning court, Dian Keling, who was over 60 years old, choked up and accused the thief of the shameless crimes at Qin Shihuang who was sitting on the dragon throne.

Dianke was in charge of the affairs of the princes and the leaders of ethnic minority tribes, received officials from various counties and counties, and usually managed some temporary official business trips and other affairs. Although he was ranked among the Nine Ministers, he was basically one of the two most idle ministers, just like Zong Zheng. He could have or not. He was just inherited according to the official positions of the Zhou Dynasty. According to the three provinces and six ministries designed by Chen Xu, these two nine ministers were reformed into two offices under the Ministry of Rites and the Shaofu, and their power and status were greatly reduced.

"Your Majesty, this thief is so rampant that he stole the houses of eight officials and ministers for six consecutive days, and harmed countless poultry and livestock. Poor that dozens of chickens and ducks in my house were cut off their claws and wings. The next day, even the duck necks hung in the kitchen were cut off overnight. It was simply... it was a beast... I suggest that you must be severely punished!" Zhisu Nei Shi Gaoteng stood up and shouted loudly, his beard and eyebrows were shaking as he spoke.

Late at night six days ago, his family was the first one to be visited by thieves. Dozens of chickens and ducks were all broken overnight and their legs and claws and wings were cut off. They were just poultry, and they died. Although Gao Teng was angry, he didn't care too much. He ordered his servants to pull their hair and remove their internal organs and then hang them up and dry them. However, he did not expect that the next night the thief came again and cut off all the duck necks. The duck with no legs, feet, wings and neck were thrown all over the floor. Therefore, when he heard the servants report the news the next morning, Gao Teng almost spit out an old blood after seeing the scene.

"Gao Neishi said it well. The seven sheep in my mansion were cut off the hooves the day before yesterday. They died so badly!" A minister in his fifty years old stood up and said.

"The same is true for me. In order to cut off the pig's ears, the thief cruelly cut off the heads of five big fat pigs, and blood was everywhere. He visited him again the next night and cut off the pig's nose..."

"Your Majesty, Xianyang is the capital, with a population of one million. How can you tolerate such shameless behavior? I suggest that Your Majesty issue an order to ask the Lieutenant's Mansion to search for thieves, so as not to disrupt the capital's public order and cause panic and chaos among the people!" Another minister in his fifties also stood up and said.

"I commented on it! Although the thieves stole nothing worth mentioning, disturbing the capital is a serious crime and cannot be condoned. I once suggested that the Lieutenant's Office quickly arrest and then severely punish it!"

"I'm going to discuss it!" A large group of officials stood up and posted.

Qin Shihuang sat high on the dragon chaise. Although his face was as calm as ever, he could clearly see his skin twitching a few times.

In fact, he could instantly think of this matter, which was probably related to the braised dishes developed by Qinghehou.

In this era when the dishes were either salt-cooked or grilled, the emergence of braised dishes fully developed the taste of people. It turned out that the dishes could be cooked like this, and so many seasonings were added. Moreover, the feet and wings that were braised were much better than meat. The palace had never lacked meat, but neither the emperor nor the concubine had ever eaten such delicious things. Compared with the hot pot meal, braised dishes were more suitable for drinking, entertainment and snacks, and were extremely popular in the palace. The emperor also liked to eat some when he was reviewing memorials, which also led to the value of chicken feet and duck feet in Xianyang's time, and the supply was completely in short supply.

Although there are not many civil and military officials in the court who know that there are many people who have eaten some of them, there are only two who can make braised dishes, one is the Qinghe Hou Mansion and the other is the imperial kitchen in the palace.

Nowadays, the backyard of Ganquan Palace can smell the strong braised fragrance every day, just like the Qinghe Hou Mansion.

Therefore, if this matter is really to be investigated, the two people will be found in the end, one is the Marquis of Qinghe and the other is the Emperor.

Qin Shihuang could not guarantee that it was not arranged by the imperial kitchen. Even if it was not made by the imperial kitchen, it might have been made by concubines, princes and princesses. There are too many masters who climbed over the wall like walking on flat ground and walked without a trace in the palace.

The Queen of Qinghe could not guarantee that these dishes were invented by him. If he didn't like to eat them, how could he make such delicious food? Maybe it was arranged by the Queen of Qinghe.

But no matter who does it, it is best not to continue to investigate. Once it is clear, it will inevitably be embarrassing.

Seeing that Qin Shihuang had not spoken for a long time and his face was a little depressed, the left prime minister Li Si stood up: "Your Majesty, the things stole by this mysterious thief are all inedible things like bird claws and animal ears, and they are all committed crimes late at night. Xianyang is so big, with more than 200,000 households and a population of more than one million. If you want to investigate, I am afraid that the labor force will return in vain. The gain is not worth the loss. I suggest that there is no need to mobilize the troops like this!"

"Your Majesty, Li Xiang's words are reasonable. The lieutenant and imperial guards' search for a mere animal matter will only cause more chaos in the capital. I suggest that some people can be arranged to inquire secretly, and you must not make a big move!" Right Prime Minister Feng Quji stood up and said calmly.

"Your Majesty, the two prime ministers are right. I heard that this thief is coming and going without a trace. Although there are experts in my Lieutenant's Mansion, I am afraid that it will not be able to capture him after I have been tracked down. Moreover, the stolen master's mansion has not lost money. I have used my imperial guards for the sake of my personal gain. Once this is opened, I am afraid that the threshold of my Lieutenant's Mansion will be trampled in the future. Moreover, all the master's mansions have servants and guards, so I secretly search by myself. If I find it, I can inform me. Lu must arrange for elite troops to capture him!" Lu Xiao turned his head and looked at several officials who asked the emperor to capture the thief.

"Yes, the lieutenant and imperial guards are the masters who guard the capital. How can we make a big fight for a thief? Once an abnormal situation occurs, the capital will be in danger!" A doctor stood up and said loudly.

"I'm going to discuss it, it's not easy for me to make a big fight!" A large doctor stood up and posted it.

"Well, this matter is indeed not easy to cause any big fuss. After you return to your house, arrange for the guards to be alert. Don't panic too much!" Qin Shihuang's face relaxed and then he made a final decision.

So several stolen ministers in the family sat down with depression.

And Qin Shihuang was also very depressed.

Just a trivial matter wasted half an hour of court discussion.

For example, today, more than 800 counties in the next 36 counties and more than 800 counties sent hundreds of memorials to Xianyang every day, and all these memorials must be processed. The morning and afternoon dynasties were too short for nearly two hours, and other military and political affairs that need to be arranged every day were discussed. Therefore, in addition to attending court, Qin Shihuang also had to take time to review a large number of memorials every day, and there were records in the Records of the Grand Historian. Qin Shihuang worked diligently and had to read one stone memorial every day, that is, a 120 kilogram bamboo slips. This is a very heavy physical and mental work. Without strong perseverance, he could not withstand decades of persistence. Therefore, from the perspective of governance, Qin Shihuang was definitely the most diligent emperor in Chinese history.

But the incident of the morning court made him very angry.

Therefore, after the court scattered, he returned to Zichen Hall, sat on the warm couch and rested for a while, and then suddenly swept the teacup on the table with one sleeve to the ground and smashed it to pieces.

"Your Majesty calmed down!" Both the inner officials and the guards and palace maids were all lying on the ground in fear, trembling with fear and wondering what had happened.

"Come here, please come and ask the Marquis of Qinghe to enter the palace!" Qin Shihuang's emotions slowly calmed down after his anger ejaculation.
