The sudden speech of the boss in the sky successfully disrupted the rhythm of Mr. Tang.

Boss, why are you doing nothing serious every day?

I'm spying on me all day long, are you not afraid of needle holes?

Fortunately, you can't see through my thoughts...

"Um."

Tang Ning, who was a little panicked, quickly chose to respond. After all, this kind of cold answer should help consolidate the character of a paranormal expert...

"Please teach me Mr. Tang!"

Perhaps because of being neglected, Hua Yuanhua, who had not figured out "being good at things" and sent a request full of curiosity.

OK, the main master is still waiting, but I don’t have much interest in teaching you.

Forget it, no matter how you kill me, no matter how you buried me, after all, the big guy in the sky is watching.

The character is not defeated.

"Master, please give me instructions."

Dian Zaixing's voice came from outside the gate, and he obviously heard Tang Ning's call.

"Old Master, can the Prime Minister be fine?"

Prime Minister Xue Chucai also asked immediately, looking very nervous.

"The poisonous arrow has been lifted out by Yuanhua, and the remaining poison has been removed by the poison-eating golden toad. Your prime minister has awakened. Xue Changshi does not need to worry, you will see him in a moment."

Tang Ning chose to answer Xue Chucai's question loudly first. After all, his stupid son Tang Boyan is their backbone. Only by releasing this good news can everyone who is uneasy and waiting outside.

This is true. Before Tang Ning finished speaking, a low cheer was heard outside.

"Zaixing, you can wait at the door first. When I call you again, you can come in."

Tang Ning ordered again.

"promise."

Dian Zaixing responds to the truth.

"Yuanhua, have you ever played with crystals? The colorless and transparent ones."

After dealing with Tang Ning outside, he turned his gaze back to Hua Yuanhua.

Hua Yuanhua shook his head, what's fun about crystals? If you can't eat them but cannot use them, you still feel heavy on your body...

Hua Yuanhua's interests are all on silver needles and scalpels, so he is not very interested in women, let alone crystals.

"Young people, so you should be good at using things." Tang Ning transformed into Chunchun elder and heuristic education: "Many years ago, I played with a few colorless and transparent crystals. I accidentally discovered that the size seen by other items through the crystals is different from the actual size of the item. Those items are visible to the naked eye. Why is this? I was very interested, so I finely ground the crystals and ground them into two convex and transparent shapes... What do you think?"

"See those invisible creatures in the air?"

Hua Yuanhua quickly replied.

Young man, you are thinking about nothing.

If bacteria are so easy to see, is it necessary to invent a microscope, which I am not very clear about very much?

"I found that the convexity of the grinding is different, and the size of the external objects observed through it is also different. So I wondered again, can we use the actual size of the observed object as a reference to determine the magnification of crystal lenses of different convexities?"

Tang Ning looked at Hua Yuanhua, who was listening carefully with wide eyes.

Hua Yuanhua looked around and then raised his hand to point at his nose, and asked replies with great uncertainty: "Duke Tang, you... ask me?"

Why--

The imperial physician who was attending the audience wanted to cover his face again. Did I misunderstand it? Is this guy Hua Yuanhua's brain lacking a string? I really want to split it with one knife!

"Yes, I'm asking you."

Tang Ning still maintained the demeanor of a pure elder.

So Hua Yuanhua's eyes were out of focus, and his hands were squirting like a wind... It seemed that he was busy simulating imagination in his mind.

After about thirty breaths, Hua Yuanhua suddenly came back to his senses, and his emotions were instantly converted into excitement: "Mr. Tang, I understand! What you mean is that as long as the polishing is exquisite enough, you can create an ultra-large crystal convex lens with a magnification of a sufficiently large magnification, right? Haha, using this ultra-large crystal convex lens with a high magnification, you will definitely see the invisible creatures that cause wound ulceration and septic blood!"

“…”

I just asked if you can determine the magnification. Why are you talking about so much? And your monolithic lens is wrong?

Tang Ning also wanted to cover her face.

Heuristic teaching is probably a failure.

"In fact, a single crystal convex mirror cannot observe the invisible creatures that cause wound ulceration and septic blood." Tang Ning decisively denied Hua Yuanhua's delusion, and then he simply said the correct operation: "Place the two crystal lenses at both ends of the circular tube and carefully adjust their distance, so that they can barely achieve microscopy."

Hua Yuanhua closed his right eye and tilted his head slightly, then compared two ok gestures in front and back with his hands, gestured back and forth twice, and finally realized: "Mr. Tang, I understand! I really understand this time!"

Tang Ning nodded. After all, he didn't understand the internal structure of the microscope, so he could only give this idea and let Hua Yuanhua do it himself.

"Father, if you look into the distance with a made-up lens, can you see the people and scenery in the distance?"

A treacherous person who was also listening to the class seriously suddenly asked.

Um?

Bad boy, you are too fast to think in reverse?

Hurry up and withdraw your words and say again when you change your father!

Tang Ning glanced at a traitor.

Tang Boyan was a little nervous when he was seen, thinking to himself that I had said the wrong thing again and made my father unhappy? No... I am so smart, my father should praise me?

"In fact, even if you can't see the invisible organisms in the air that can cause disease, there are still ways to reduce the probability of surgical wound infection. For example, when you try to eliminate idle people during the operation, and how to control visitors after the operation are all right. Yes, have you disinfected the scalpel before the operation?"

Hua Yuanhua has really heard of the new word "disinfection?" before, but after a little confused, he understood what Tang Ning meant: "Duke Tang, before applying the technique, he would soak the knife in strong wine first, and then burn the knife in strong fire."

"Good job!" Tang Ning affirmed and was relieved: "Yuanhua, have you ever thought about building a special house with high sealing properties for an operating room? Before the operation, replace the surgical gown with disinfectant sprayed with alcohol, and then use disinfectant to clean your hands. Will the surgical environment be cleaner? Oh, also, do patients need disinfection when undergoing surgery? Well, that's all, only practice can lead to true knowledge-"

"I'm happy, I can come in. I'm a little tired. Let's carry me back home!"

Mr. Tang actually wanted to say more. The problem is that he has limited knowledge of medical care and can only pretend to be a rush and run away quickly.

It’s impossible not to run away. If the surgeon of Huayuanhua, a genuine brand, asked about a lot of professional knowledge, he would definitely reveal his feelings...

Dian Zaixing pushed the door open and Xue Chucai also stumbling in.

Looking at the thoughtful Prime Minister Tang, who had indeed woken up and was thinking, Xue Chucai finally breathed a sigh of relief.

No one knows how much psychological pressure was from the moment when King Wei was assassinated.

Xue Chucai knew better than anyone else about the poisonous arrows used by the assassins - the dark blade dead soldiers who guarded the King of Wei, the yamen runners responsible for the security of the periphery, and the soldiers of the Southern Army. No matter how strong or weak, anyone who was shot was shot, no one who had died was left!

Really, if the King of Wei was unfortunately assassinated, how serious the consequences would be... I can't imagine it at all.

Did the old man take action and Wan Tianqing rescue King Wei?

Xue Chucai's nose swayed slightly, and he smelled a faint fragrance of spiritual medicine.

That’s right, where did the spiritual medicine come from in this poor place of the Taishu Hospital? The spiritual medicine can only be brought by the old master.

Speaking of which, the old man is very caring for the King of Wei. Since the King of Wei brought him to the palace from his hometown in Yuezhou, he has repeatedly helped the King of Wei.

With such a father who is so powerful that he seems to be omnipotent, King Wei is really lucky in his three lives...

Xue Chucai couldn't help but look at Old Master Tang sitting in front of the operating bed, with a faint envy in his eyes.

That's right, I'm really envious. After all, who wouldn't want such a pretty good and perfect father?

"Prime Minister."

Xue Chucai walked to the edge of the operating bed and gave a deep salute to Tang Boyan on the sickbed.

"Chu Cai, I have told you countless times, and there is no need to be polite between you and me." Prime Minister Tang, whose physical condition has quickly recovered from the nourishment of the spiritual medicine, can already speak in a relatively normal voice: "What's the situation outside? Can anyone who is not afraid of death jump out?"

Xue Chucai shook his head, looked around and leaned over to Tang Boyan's ear and began to whisper.

"oh?"

Prime Minister Tang's eyes quietly narrowed.

The imperial physician Jia Zhongjing had already paced to the next door before Xue Chucai started talking.

Hua Yuanhua was still standing there and whispering, and was muttering something in his mouth. He didn't know what he was talking about. His surgical assistant was walking next to him, nor did he not leave, and his expression was very awkward.

"Lord, your legs?!"

Dian Zaixing's attention was all about Tang Ning.

"It's okay, I will recover in a few days." Tang Ning, who knew his family affairs, waved his hand: "Borrow me back home first."

In terms of comfort, the official hat chair I sit in is far worse than the wheelchair at home.

Dian Zaixing nodded, and then easily picked up Old Master Tang.

"Let go! Let go! Let go!"

Tang Ning shouted.

Dian Zaixing, you are awesome. Isn’t what I said clearly enough?

What I said is whether you can carry it well! Carry it! Carry it! Carry it!

Who asked your princess to hug you, bastard!

If you want to hug me like this, believe it or not, wait until you return to the mansion. I will assign a big-sleeved and round-waisted cook to keep you hugged me all day long!

Old Master Tang was so angry that he was embarrassed.

"Father, what's wrong with you? But what's wrong with you?"

Tang Boyan looked at Dian Zaixing's biological father with concern.

"Shut up! It's all your business! No one thinks you are mute if you don't say anything!" Old Master Tang, who was embarrassed, irritated his anger on his stupid son: "Talk about your military and national affairs!"

Prime Minister Tang, who had long been accustomed to being scolded by his own father in a fancy way, confirmed that his own father should be fine, then shrank his neck and did not dare to speak again, for fear of attracting more "father's love".
