Physician of the Song Dynasty: Zhang Kai and Li Qingzhao have a private life-long contract

"Blood test is nonsense!"

As soon as the news came out in Di Bao, it aroused heated discussion among the people.

In this era, blood recognition is the only way to identify parent-child relationships. It has been used by royal nobles in the past, but it has now been proven to be false.

Suddenly, countless people's faces turned green.

"Who would have thought that a blood test would be fake?"

Beside the Royal Lake, Zhao Xu and Zhao Xu were training as usual and couldn't help but smack their tongues.

The royal family naturally values ​​bloodline the most. However, when concubines enter the palace, they will check their bodies to ensure that they are virgins. Moreover, the palace is full of maids and eunuchs, and there are no men. In addition, every sexual intercourse in the harem is recorded, and blood is dropped to test the authenticity of the marriage. Pseudo doesn't have much impact on it.

Fan Zheng nodded and said: "Although the blood test has been proven to be untrue, blood transfusion therapy is feasible."

"Blood transfusion therapy? Is it true that blood transfusions are not allowed between father and son?"

Zhao Xu frowned and said,

Fan Zheng nodded solemnly and said: "Mr. Pang has already used animals to conduct experiments. Once the blood between father and son is mixed, there will be nine deaths out of ten."

Fan Zheng's efforts to cultivate a line of veterinarians finally paid off. Many medical ideas cannot be directly applied to the human body. The use of animals for experiments has become a trend among doctors, and the line of veterinarians is indispensable.

"What a pity." Zhao Xu frowned.

If doctors could successfully test blood transfusion therapy, more soldiers of the Song Dynasty would surely be saved.

Fan Zheng cupped his hands and said, "Wei Chen came here today to seek help from the officials."

"Ask me for help?"

Zhao Xu couldn't help but be surprised. He knew that Fan Zheng had always had a steady stream of villains, and he had never seen anything that stumped Fan Zheng.

Fan Zheng smiled bitterly and said: "I am a doctor, not a god, so naturally there are things beyond my power."

Zhao Xu laughed and said, "Then how do you want me to help you?"

"If the blood transfusion therapy is successful, the world will benefit a lot. However, Wei Chen gathered the collective wisdom of the doctors, but got nothing. Wei Chen wants to ask the Ministry of Industry to supervise the skilled craftsmen to help the doctors." Fan Zheng said solemnly.

Zhao Xu was very puzzled and said: "How can a craftsman who is going to be the supervisor know medical skills?"

Fan Zheng explained: "Although craftsmen do not have medical skills, they can help doctors create better blood transfusion equipment. Moreover, Weichen is impressed by the wonders of Kuoku and plans to use Kuoku's method. Please make a pair of them for doctors." Eyes, eyes that can see the tiniest speck of dust.”

Fan Zheng naturally knew that blood type was the most important for a successful blood transfusion, and a microscope was necessary to identify the blood type.

Naturally, it was impossible to build a microscope with the technological level of the Song Dynasty. Fortunately, it only required a microscope that was forty times more powerful to see the cells in the blood. The only way to do this was to create a powerful craftsman.

"allow!"

Zhao Xu naturally agreed.

"Thank you, officials!"

Fan Zheng was overjoyed and couldn't wait to leave and go to the general's prison.

………………

Will be jailed!

"Gongshu should have met Master Fan!"

Fan Zheng came with the official instructions in hand, and the general did not dare to neglect, and immediately sent out highly skilled public transportation personnel to assist Fan Zheng.

"Master Gongshu is so polite. I hope Master Gongshu can help the doctors this time," Fan Zheng said solemnly.

"I wonder what Lord Fan wants to create?" Gongshu Ying asked.

Fan Zheng solemnly laid out his ideas for the microscope.

"It can magnify an object forty times! Is this impossible?" Gong Shuying suddenly opened his eyes wide and looked at Fan Zheng in disbelief.

The most he could do was to magnify an object several times. Being able to let an old official see documents clearly was already an incredible achievement, but magnifying it forty times was simply a fantasy.

Fan Zheng raised a presbyopic lens and looked at the enlarged text inside. He smiled slightly and said, "A convex lens cannot magnify an object more than forty times. What if two convex lenses are superimposed together? "

Fan Zheng immediately put the two coins together and handed them to Gong Shuying.

Gongshu Ying couldn't help but be shocked when he saw the words enlarged more than ten times in Kuili.

"How can it still be like this?" Gongshu Ying said in disbelief.

Fan Zheng nodded. Since the two convex lenses can be magnified more than ten times, theoretically speaking, it is not impossible to reach forty times.

However, Gongshu Ying smiled bitterly and shook his head: "Master Fan's recipe is indeed magical, but it is still difficult for me to complete it."

Fan Zheng frowned and said, "Why is this?"

Gongshu Ying said helplessly: "Firstly, although the crystal is transparent, it still has many flaws and is not completely transparent. Secondly, no matter how superb the polishing process is, the surface may appear as smooth as a mirror, but after magnification, ox hair lines will appear, let alone four Ten times, that is, magnified twenty times, I am afraid it will be impossible to see clearly.

"Ox hair pattern!"

Fan Zheng frowned, picked up a polished crystal and magnified it with a lens. Sure enough, there were fine lines of cow hair formed by polishing.

"Sure enough, there is no shortcut in medical skills!" Fan Zheng sighed inwardly.

Fortunately, he had a backup plan, artificial glass.

"Glass, you don't know what glass is?" Gongshu Ying asked confused.

Fan Zheng replied: "Glass and colored glaze are essentially the same, but glass is simpler to make. It only requires sand and lime to make it."

"How is this possible?" Gongshu Ying said in shock.

You must know that glass was extremely valuable in the Song Dynasty, and sand and lime were available everywhere, so how could they be compared.

"Master Gongshu will know after just one try!"

Fan Zhengxin said.

Gongshu should be dubious and follow Fan Zheng's method of mixing, grinding and pulverizing the gravel and lime, then sending them to the crucible for smelting over a large fire.

Released!

cool down!

When a large piece of translucent glass appeared in front of him, Gongshu Ying said in disbelief: "It's so simple."

The glass in front of Fan Zheng was just the most primitive glass, with a lot of impurities and bubbles, and not enough transparency.

However, Fan Zheng was not disappointed. Under his guidance, Gongshu continued to improve the formula after many repeated experiments.

Finally, a colorless and transparent glass product appeared in front of the two of them.

"It's done"

Fan Zheng was filled with ecstasy.

With transparent glass, doctors can conduct various medical experiments.

With transparent glass, there is no need to use expensive and rare colorless crystals to create kuei. Cheap glass kuei will benefit scholars all over the world.

With transparent glass, microscopes will be at your fingertips, and doctors will enter a new era, and doctors will be able to see through

The great success of the medical profession is imminent.

With transparent glass, the most difficult step in building a microscope was finally completed. With Gong Shuying’s exquisite workmanship, an original microscope was finally completed.

Its shape was much simpler than that of later microscopes, and its clarity was also far different, but Fan Zheng regarded it as a treasure. It was a priceless treasure for doctors.

Fan Zheng looked at Gongshu Ying, who was still shocked, and couldn't help but thought: "I wonder if Master Gongshu is willing to join the medical family?"

"Join a medical family? I'm just a craftsman, but I don't have medical skills!" Gongshu Ying said in confusion.
