Chapter 571 Imaging

Li Er still looked at Gu Qing suspiciously, the monarch and his ministers stopped talking, and the Ganlu Palace fell into silence again. The sun entered the palace and shone on Gu Qing. After a long time, Wang Qin walked in, "Your Majesty, it's time to eat."

"I know." Li Er waved his hand towards Wang Qin and asked Gu Qing again, "I have seen Su Dingfang's memorial, and I understand what you did to Tubo. Do you want to assimilate Tubo?"

"Just doing it handily."

"You go back."

Gu Qing saluted first, "The minister will take his leave first."

Li Er nodded and said nothing.

East Palace

The current East Palace has become the second Zhongshu Province, and Chu Suiliang is helping the prince to deal with the memorials left by various places.

Many officials here in Li Chengqian are discussing political affairs. Although it is Hugh Mu, as the prince, he is still not idle. The king of Persia has announced to the world that Persia has become a vassal state of Tang Dynasty. He sent troops to garrison Persia first, and now he will send troops Officials go to Persia.

Looking at the roster in his hand, Li Chengqian did not write for a long time.

"His Royal Highness." An official from the Hongwen Museum came and said, "There are thieves near Youzhou. This is an urgent report from Youzhou."

After receiving the report, Li Chengqian reported, "Send government soldiers to suppress."

Another official came with a memorial, "His Royal Highness, this is a memorial from two schools in the south of the Yangtze River,"

Merchants in Jiangnan Province hoped to join this sea trade. After reading this memorial, Li Chengqian fell into hesitation. Gu Qing has always been in charge of the sea trade. Since the establishment of the port, it was his father who had already acquiesced to let Gu Qing came to preside over the matter of maritime trade, and it is true that only Gu Qing knows the affairs of the sea best.

After several considerations, Li Chengqian handed over the memorial to Chu Suiliang.

After reading it, Chu Suiliang said to Li Chengqian clearly, "His Royal Highness can preside over the meeting between Jiangnan merchants and Gu Qing. At the beginning, His Majesty also handed over the affairs of the East China Sea to His Royal Highness. His Royal Highness also has the right to intervene."

After listening to Chu Suiliang's words, Li Chengqian looked at his busy East Palace, and unexpectedly found that he seemed unable to order Gu Qing. In comparison, Gu Qing seems to have become a mountain in his heart unknowingly over the years, an insurmountable mountain, this mountain is too heavy for him to cross, Gu Qing has too many achievements.

Even if he proclaims himself emperor in the future, Gu Qing may be able to overthrow him with a single word. The emperor's father is right. Gu Qing has a double-edged sword, which can expand the territory, suppress Mobei, exterminate Tubo, and the Hexi Corridor. No one dares to offend, and it can also cause chaos in the world.

"His Royal Highness?" Chu Suiliang looked at Li Chengqian's puzzled expression.

"Chu Suiliang." Li Chengqian whispered, "Do you think Gu can control Gu Qing?"

"Impossible." Chu Suiliang said very straightforwardly, "Has His Highness the Crown Prince not noticed the way Gu Qing gets along with His Majesty?"

The memorial in Li Chengqian's hand has not been put down for a long time, "How do you say that?"

"Although your majesty and Gu Qing are monarchs and ministers, they also have a lot of similarities, and they gain mutual benefits." Chu Suiliang bowed and said, "His Royal Highness can't think of controlling Gu Qing, but wants to get what he needs with Gu Qing. This person has a perverse personality, and he does things casually, but fortunately, he has no covetous heart for power, His Royal Highness may as well sit with Gu Qing and have a long talk when he is free, and he will definitely gain something."

East Palace is very busy

After returning home, Gu Qing also started to get busy. The principle of small hole imaging is very simple. Mozi and his students have studied this principle as early as those years ago, but it is not easy to make a camera.

Li Zhi sat and watched Gu Qing's fiddling for a long time, but he still didn't understand, "Gu Qing, why is this shadow upside down."

"Because light travels in a straight line." Gu Qing was busy with his hands and feet, "You don't understand, can His Highness King Jin find some craftsmen?"

"Do you want one from the palace?"

"No need." Gu Qing said, "Just find a few people who can do woodwork. It's not difficult to make a black box."

"What are you going to do?" Li Zhi asked suspiciously.

"Camera." Gu Qing thought, "A thing that can leave images of people, does His Royal Highness know what optical imaging is? Do you know the irradiation of light? Do you know the speed of light?"

Li Zhi shook his head vigorously.

"If you don't know, hurry up and find some craftsmen who can do woodwork."

Li Zhi walked out of Gu Qing's laboratory, slammed the door and came to the courtyard with a dark face, "Fan Jian, come here for me."

"What orders does His Royal Highness Prince Jin have?" Fan Jian hurried over.

"Gu Qing wants some craftsmen who can do woodwork to make something called a camera obscura." Li Zhi said, "Hurry up and find some craftsmen."

"Yes!" Fan Jian left respectfully.

camera?Li Zhi thought about it, something that can leave a human image?Is this another Gu Qing's plan to make a fortune? If I can do it before Gu Qing and hand it over to my father, will my father be happy?

Thinking of this, Li Zhi immediately dispelled the idea. He has never even heard of a camera, would Gu Qing leave it to him to do it?

For three whole days at home, Gu Qing has been busy with work, Fan Jian carefully came with something, "Patriarch, this board is ready for the first time."

Putting on gloves, Gu Qing held this silver-plated copper plate, which has been polished, and it is indispensable to have a camera, "Very good."

Fan Jian smiled wryly, and it took a lot of effort to make this thing, because the silver plating skills drove away many blacksmiths.

"It's hard work." Gu Qing accepted the copper plate, "Go to Madam to give some money to the craftsmen, and you can get some yourself."

With this silver-plated copper plate, one more thing is iodine. In this era when photosensitive materials are scarce, you can only find iodine and silver. Where can you find iodine?

After thinking hard, I found Sun Simiao, "Master, do you know something called iodine?"

"Is it medicinal material?" Sun Simiao asked.

"Probably not." Gu Qing shook his head.

"I've never heard of that." Sun Simiao was observing Yang Sheng's saffron in his hand, smelling it from time to time, not sure if he would eat it.

"What if someone gets a big neck disease without iodine these days?" Gu Qing hesitated.

"Big neck disease?" Sun Simiao asked again when he heard the term, "You are talking about gall disease, right? It's not impossible to cure this."

"Huh?" Gu Qing looked at Sun Simiao with interest.

"This can be cured with black horn." Sun Simiao said lightly.

"Black horned vegetables?" Gu Qing asked suspiciously, "What black horned vegetables."

"Hehehe..." Sun Simiao smiled wryly, "You don't even know black carnation? Why did I, Sun Simiao, accept a disciple like you?"

"Master, what exactly is the black horned vegetable you mentioned?" Gu Qing asked.

"That's a kind of sea vegetable. We saw it in the East China Sea before, but Chang'an didn't have it." Sun Simiao said, "There is a kind of medicinal material called kelp that can also be cured. It is sold in Chang'an's medical clinics, and it is also available here for the teacher. The iodine you mentioned What does it have to do with the big neck disease, who has the big neck disease?"

Gu Qing slapped his forehead, forgetting about traditional Chinese medicine, the knowledge of his ancestors is still profound, "Master, give me some kombu, I will be of great use."
