"It's both."

"Then do you think this will work?" Liu Xie suggested Zhou Qun. "You first publish an article for discussion among colleagues, to verify theoretically whether it is feasible. Then find other glass workshops to see if they are interested in participating in the development. I can provide some money, and if it is done, I can let them sign it in the future Taishi's exclusive title."

Zhou Qun was skeptical. "Is this... okay?"

Liu Xie smiled. "How do you know if you don't try?"

Seeing that Liu Xie insisted, but didn't mention a single word to issue an edict to Shangfang Supervisor, Zhou Qun nodded helplessly.

"Then go and try."

Chapter 1108 Clairvoyant Eye

Zhou Qun was somewhat depressed.

He was very confident in his new design and felt that it would definitely surpass the transmission telescope.As long as Tongtong gets the support of the emperor and orders Shangfang to supervise the trial production, it will be successful soon.

But he didn't expect that the emperor couldn't see the beauty of it. Not only did he not order Shangfangjian, but he also asked him to cooperate with the workshops in Nanyang to win their support.

This is no different from perfunctory.

He used to admire the emperor very much, but now he feels that the emperor is not so wise.

Unhappy, she went out of the door and came to the vestibule, where she was stopped by Qin Mi who was waiting here.

Qin Mi was worshiped as a minister and was on duty today. When Zhou Qun came to see him, he waited in the vestibule, wanting to chat with him about recent developments.Speaking of which, he strongly invited Zhou Qun to enter the court, and now that Zhou Qun is flourishing in the Taishi Department, he is also happy.

Seeing Zhou Qun depressed, Qin Mi was a little surprised, led Zhou Qun to a remote place, and asked a few words.

Zhou Qun explained the situation again, and then complained: "I have done experiments, the reflection has no chromatic aberration, and it is better than the transmission mirror, so it can be made bigger, but it is not bulky, and it is hundreds of times better than the transmission mirror. Knowing the beauty of it, it is not allowed."

Qin Mi didn't speak immediately, but after thinking carefully for a while, she asked Zhou Qun to spread out the drawing and shook her head.

"Brother Zhongzhi, with all due respect, your design is indeed brilliant, but there are also many difficulties. Among other things, the reflection of this bronze mirror is not as bright as the transmission, and it is obvious to all. It may be reluctant during the day, but at night..."

Qin Mi didn't continue, but Zhou Qun understood, slapped his forehead, and said dejectedly: "Neglected, negligent."

Bronze mirrors are commonly used, so Zhou Qun naturally understood that what Qin Mi said was reasonable.He wanted to build this telescope for stargazing, all at night.It's still blurry in a room, not to mention the stars thousands of miles away in the night sky?

In this way, when the emperor asked him to discuss cooperation with Nanyang Workshop, it was not perfunctory, but a polite refusal.

Qin Mi didn't think so.

He told Zhou Qun that there are many mirror workshops in Nanyang. They not only make telescopes, but also copper mirrors for daily use.Because of the fierce competition, they put in a lot of effort. Some workshops worked hard on grinding, while others spent a lot of thought on materials. They all came up with new ideas to win, and improving the reflective brightness is one of them.

In this regard, non-governmental workshops have more experience and ideas than Shangfangjian.

After hearing this, Zhou Qun was skeptical, but still went to prepare.

A few days later, Zhou Qun published the article first, and then the Taishi Department called several powerful workshops in Nanyang to participate in the meeting in the name of seminars to seek collaborators.

As Qin Mi said, several mirror-making workshops were very interested, and one of them proposed a solution to the lack of brightness.

Using silver as a mirror, or plating a layer of silver on a copper mirror, and then grinding it, the brightness can be improved by several levels.

This, they have tried.It's just that the cost of silver plating is too high for ordinary people to afford, so it can only be sold as a luxury item at present.If it can be labeled with the Taishi Department, it may help to increase its popularity.

Of course, rather than the labels of the Taishi Department, they hope that their own products can become tributes, so that the queens and nobles in the harem can use this high-brightness silver mirror and publicize it for them.

The two sides hit it off.

Zhou Qun patted his chest and said, I will report your request to the emperor and try to get his approval.

The representative of the workshop was very happy, and when he went back, he was sent a beautiful silver mirror with two sides.Zhou Qun immediately sent the two silver mirrors to Liu Xie.

Liu Xie was also surprised by the cleanliness and brightness of the silver mirror.

Nanyang is worthy of being the hometown of an emperor. There are many rich people and various crafts are developed. To be able to manufacture such a delicate and clean silver mirror with such a high reflectivity far exceeded his expectations.

It seems that it is necessary to conduct a thorough investigation of Nanyang's technological level.

Such a bright silver mirror should be no problem for making reflecting telescopes, and Zhou Qun is one step closer to his goal.

Of course it's just one step.

Although the reflecting telescope can solve the problem of chromatic aberration, it cannot solve the problem of spherical aberration. There is still a long way to go to build a qualified astronomical telescope, and even he cannot solve it.

He is also not very clear about those details, and can only count on more people to explore.

Liu Xie politely rejected the workshop's idea of ​​becoming a tribute and promoting it in the name of the court.

He told Zhou Qun that the imperial court had no money, and the size of the harem was reduced as much as possible, so they could not afford too many luxuries, and he did not want to create an atmosphere of extravagance.I can provide part of the cost of your telescope development, and the tribute will be avoided.

Zhou Qun didn't care either.

As long as it can be made into a telescope, he doesn't care about the rest.Besides, the emperor practiced frugality, and he couldn't get what he wanted, and there was absolutely no reason to persuade the emperor to be extravagant.

Save money, just use it for research.

After repeated negotiations, the workshop also gave in, and signed a cooperation agreement with the Taishi Department to jointly develop telescopes dedicated to stargazing.

After more than a month of hard work, the first reflecting telescope came out.

There is no chromatic aberration, and the brightness is acceptable, but the effect is not as good as Zhou Qun expected. The images of the stars are blurred and not as clear as the transmission telescope.

Zhou Qun was hit hard, thinking hard.

At this time, an article was published in the Di newspaper, predicting Zhou Qun’s previous article, mentioning that when the spherical surface is small, image deformation and blurring outside the axis will occur, and a possible solution is proposed mathematically.

Zhou Qun was shocked after reading the article, and immediately found the young scholar named Zhao Shuang and invited him to participate in the development of the reflecting telescope.

Compared with Zhou Qun's troubles in developing the reflective telescope, Shang Fangjian's development of the transmissive telescope has been relatively smooth.After solving the material problem, a telescope that meets military requirements was quickly developed, expanding the field of view by two to three times.

After acceptance, Liu Xie ordered the manufacture of the first batch of military telescopes, a total of twenty.

Ten of them were handed over to the martial arts hall for teaching and practice, and Shangfang Supervisor was used to provide feedback.

The ten are numbered with heavenly stems and distributed to the generals who fight on the front line and some important generals who guard one side. They are not only combat weapons, but also a kind of honor.

For example, although Hussar General Zhang Ji broke away from the front line, he also got a telescope, numbered B.

Knowing that there were only ten generals who got the telescope, and he was one of them, Zhang Ji was inexplicably grateful, and immediately expressed his thanks.

Also thanking Han Sui, numbered Ding.

Han Sui supervised and led the two states of Yanyu, but he had no combat missions.After receiving the telescope, he knew that the court had not forgotten him, and the emperor had not forgotten him. He was in a good mood and wrote a warm thank you letter with his own hand.

Ding Chong, the new General Zhengnan who formally succeeded Zhang Ji, also received a telescope, numbered Geng.

There are tens of thousands of troops in the entire Jingnan area, only Ding Chong has been rewarded, and the court's support for him is very firm.After Ding Chong received the telescope, he expressed his gratitude and sent someone to deliver the telescope to Sun Ce's army, saying that Sun Ce needed such a sharp weapon more than he did, and he could lend it to Sun Ce first.

After receiving the telescope, Sun Ce was very satisfied, and immediately wrote back. In addition to thanking him, he reiterated his support for Ding Chong, and said that all preparations have been made, and he can enter Jiaozhou after autumn.

Chapter 1109

Jian'an eight years, autumn.

Runan, Yuan's ancestral tomb.

Yuan Tan squatted in front of Yuan Shao's tomb, stretched out his hand to pull out some newly grown weeds, and sighed.

Standing behind him, Guo Tu described him as thin as a bamboo, but there are a few more people who are clear and handsome, his eyes are as calm as autumn water, with a hint of depression.

Several knights stood in the distance, leading their war horses with their bags on their backs.

"Xiansi, it's getting late, it's better to leave early."

Yuan Tan stood up, looked at the dirt on his hands, and sighed again. "Guo Gong, I will entrust you in the future."

"Don't worry, I will come to worship him on time. Even if I can't move, I will arrange for my children to come, and we will never let weeds grow on Benchu's grave."

Yuan Tan nodded, turned around and said to Guo Tu, "Your Majesty, take care of yourself and wait for me to return after my achievements."

Guo Tu smiled. "Only in this way can we live up to our roots."

Yuan Tan also laughed, took two steps back, and bowed his hands to Guo Tu.

Guo Tu bowed slightly and returned the salute.

Yuan Tan got up, turned and walked towards the horse.He strode like a meteor, with his hand on the hilt of his sword, describing it as heroic.In the past few years of guarding Yuan Shao's tomb, he has not been idle. He practiced martial arts during the day and studied at night. He worked harder than when he was young.

This time, he was going to Nanyang to take the free riding test again.

The imperial court has just issued an edict announcing a new election method.Both essays and martial arts have to be tested, and the most demanding test among military officers is casual riding.To become a loose rider is already the highest goal of young people who are interested in the army.

Yuan Tan is no longer young, but he still wants to take the Sanqi test, even if he can't become a Sanqi servant in the end.

Examination of Sanqi and Lecture Hall are different from other subjects. Instead of taking the exam in the county, you go directly to it.With Yuan Shao's death humiliating and counties avoiding it, Yuan Tan didn't have much choice.

Of course, he can also leave the Central Plains and go overseas to join Liu Bei.

When Liu Bei was the governor of Yuzhou, he was once regarded as a talented person, which can be regarded as an old love.Now that Liu Bei is building a country overseas, most of the military and civil servants under his command have Yuan Shao's old department, and even his younger brother Yuan Xi is there.If he is willing to go, it goes without saying where he will stand.

He can also choose to go to northern Xinjiang, whether it is the Youyan Dufu Mansion or the Yanran Dufu Mansion, he can have a place for him.

But he refused all of them, he was going to take the Sanqi test, or lecture in the martial arts hall.

He wants to prove that he has such ability.

Yuan Xi also agreed with such a decision, and sent him two Wuhuan good horses and bows for him to practice riding and shooting.

Leaving Ruyang, head west all the way.Half a month later, Yuan Tan arrived at Nanyang Wancheng.

He rushed to Situ's mansion immediately to meet his aunt, Mrs. Yuan.

Mrs. Yuan is playing with her grandson and granddaughter in the backyard.

Yang Xiu didn't come to participate in the plan this year, so his wife brought a pair of newborn twins to Wancheng to visit his parents.Although the two children were not yet one year old, they were healthy and lively, and Madam Yuan loved them so much that she couldn't put them down, and they even arranged to sleep in their own room, but Yang Biao was kicked out.

Seeing Yuan Tan, Mrs. Yuan was very surprised and temporarily put down her grandson and granddaughter.

"Xiansi, I haven't seen you for a few years. You have changed a lot. You are dark and strong, and you are somewhat similar to Dezu."

Yuan Tan heaved a sigh of relief, bowed to Mrs. Yuan, and then reported on the experience of the past four years.

Knowing that Yuan Tan has been guarding Yuan Shao's tomb, Mrs. Yuan is very satisfied.In any case, this kind of filial piety is rare.

She knew that with Guo Tu's connections, it would not be difficult to arrange Yuan Tan to Youyan Dufu.

"You want to take the Sanqi test, do you really want to join the army, or do you want to strive for success?"

"It's both." Yuan Tan didn't hide anything, and directly stated his intentions.If he wanted to get rid of the shackles of his status, he had to seek Madam Yuan's help. "My grandfather was also General Du Liao back then, so this can be regarded as inheriting his behest."

Madam Yuan smiled. "Xiansi, I wish you had such an ambition. But I also want to remind you that the emperor's western expedition is a foregone conclusion, and it will not exceed ten years at the most. The Western Regions are thousands of miles away, and the conquest may be more painful than you imagined." Many, and may not come back in the future.”

"There are four younger brothers guarding the ancestral tomb in the Central Plains. It doesn't matter how far our elder brothers go."

Mrs. Yuan was taken aback, and after careful questioning, she found out that Yuan Shao's youngest son, Yuan Mai, had already returned to his hometown in Ruyang.His mother, Yuan Shao's stepwife, the Liu family, also returned to Ruyang, and was not in Yuan Xi's army.

The reason why Mrs. Yuan did not receive the news was because they had not been pardoned by the imperial court at that time, and they were still sinners, so it was inconvenient to disclose them.

As Mrs. Yuan said, overseas conquests are very hard, and neither Liu nor Yuan Mai can bear it.Yuan Xi had no choice but to find a way to send them back.At first, he lived in Donglai, Liu's hometown, for a while, and then quietly moved to Ruyang.

After hearing this, Mrs. Yuan's expression changed.

Liu Bei Jianguo, Yuan Xi and others were also pardoned and became civilians, but the ban on returning to the Central Plains was not lifted.Yuan's behavior of buying mother and child is illegal, and it will be troublesome if it is really pursued.

"You came to see me because you hoped that your uncle would come forward and ask for the emperor's pardon?"

Yuan Tan saluted again. "The hard work overseas is beyond the reach of women and children. If the emperor refuses to show mercy, I am willing to be punished on their behalf."

Madam Yuan hesitated to speak, and sighed heavily.

She really wanted to reprimand Yuan Tan, but seeing Yuan Tan's appearance, she couldn't bear it.Of course she knows that overseas is not easy, especially for women and children.But what kind of temper the emperor has, she knows better.

If the emperor knows that Yuan Mai's mother and son violated the ban and returned to the Central Plains privately, God knows how the emperor will react.With the temper of the emperor, it is entirely possible to clean up again.

"Are there many people like this?"

Yuan Tan shook his head. "I don't know if anyone returned home privately, but many women and children died overseas because of unacceptable water and soil conditions. Even strong soldiers and soldiers fell ill due to poor drinking habits. Compared with the Central Plains, the conditions overseas It is too difficult, even compared with Liaodong, it is far inferior."

Madam Yuan thought about it carefully. "You write a letter back and ask their mother and son to leave Ruyang, conceal their identities, and never reveal their whereabouts. Maybe there will be a chance after the emperor goes west." She thought about it again. "Isn't Liu Zhengli the governor of Yangzhou? Let them vote for Liu Zhengli."

Seeing that Mrs. Yuan spoke cautiously, Yuan Tan did not dare to disobey, so she immediately agreed.

After sending Yuan Tan away, Mrs. Yuan managed to calm down, and after careful consideration, she decided to keep the matter a secret and not tell Yang Biao, so as not to embarrass Yang Biao.

In the evening, when she told Yang Biao that Yuan Tan was coming to take the Sanqi test, she didn't mention anything about Yuan Mai's mother and son.

Yang Biao was very supportive of Yuan Tan's wanting to take the Sanqi test, and immediately expressed his willingness to explain to the emperor, asking the emperor to give Yuan Tan this opportunity.Although Yuan Shao was guilty, he had been pardoned by the emperor before his death. There was no institutional problem with Yuan Tan's test of Sanqi, it was only whether the emperor was willing to accept it.

Based on his understanding of the Son of Heaven, he thought that the Son of Heaven would not be so narrow-minded.
