Man of Steel is easy to understand, and the system NPC doesn’t explain much.

"Teacher, what does Ming Qi Qiu say about resolution and refresh rate? What do they mean?"

Ji Xiang had psychological expectations when he asked this question.

Based on his understanding of system NPCs, he would definitely explain a lot of basic theory to himself first.

As expected by Ji Xiang, the system NPC began to talk at length.

"Resolution depends on the number of cones and rods.

The human body contains 6-7 million cones, responsible for color recognition and vision in brighter environments.

Rod photoreceptor cells: about 125 million, responsible for vision at the edge of the line of sight at night, without color perception, and containing a light-sensitive substance."

"..."

Ten minutes later, the system NPC finished speaking.

"Let me give you an example."

Ji Xiang finally got to the point where he was giving examples, and his spirits were shaken.

Pure theory sounds too boring, but fortunately the system NPC always gives examples while talking about theory.

This is a good habit.

"I participated in a study of the Air Force as a human bioengineering expert."

"During the test, flashing pictures will be released, and some pilots can even distinguish the model of the aircraft, even if the aircraft picture only appears for 1/220th of a second. In other words, the "refresh rate" of the human eye is actually much higher than 120 Hz.

.”

"This is the resolution of the human eye."

1/220 seconds!

Ji Xiang was surprised that the pilots had such tough qualities!

It's really hard to imagine.

"This is an active skill. If it is a passive skill, your life will be affected." The system NPC said, "Normal people can only click and select skills when needed."

"When to use it, teacher."

"Of course it is during surgery, especially some delicate surgeries, such as microscopic surgery, interventional surgery, etc."

Another interventional surgery!

Ji Xiang felt that the rewards for this competition were completely customized, just for the interventional surgery he would have to do in the future.

If you are new to the system, Ji Xiang will definitely think that it is full of conspiracies.

"It's probably like this. If you talk too much, you'll get bored, so don't talk too much. When you use it, you'll have a deeper understanding."

"Teacher, I have another question." Ji Xiang raised his hand.

"explain."

"I now have 18.3 random attributes, where do you think I should add them?" Ji Xiang asked.

The system NPC looked at Ji Xiang with a smile, "You didn't seem to hesitate at all last time and just added luck directly."

Ji Xiang nodded, "Teacher, I think luck is very important."

"Then add it."

"What do you mean..." Ji Xiang did not expect that the system NPC would support him so "willfully" in adding all free attribute points to luck.

"Surgeons all know a fact, but no one can change it." The system NPC said, "No matter how good or careful the operation is, there is a certain probability of complications after the operation. Either infection of the incision or metastasis of the tumor.

, even appendicitis can kill someone."

Ji Xiang seemed to understand the meaning of the system NPC.

"Take a simple example, vascular thrombolysis." The system NPC continued, "The surgery of thrombolysis is very simple, just puncture and catheter placement. But during thrombolysis, small emboli will fall off, and if you are not careful, the end of the thrombosis will appear.

Blood vessel blockage can even lead to limb necrosis."

"The so-called accident is beyond the control of the doctor. At this time, what is needed is luck."

"If your luck value is high, it means that the patient's luck bonus in surgical treatment is high."

Ji Xiang nodded repeatedly.

He knows where his misunderstanding lies.

The system is a system for doctors. The so-called lucky value will not reduce the probability of having a car accident, but will only increase the probability of luck related to medical treatment.

"Another example is the partial nephrectomy surgery you are about to undergo. Whether there will be bleeding or no bleeding after the operation is related to the surgical technique. But even if the surgery is as good as mine, it cannot completely avoid postoperative bleeding."

"..." Ji Xiang thought that he had long been immune to all kinds of Versailles words from system NPCs, but when he heard him say that he was as strong as me, he still couldn't accept it.

Even if he is stronger than me... Even though he is ordinary, he is quite impressive.

"With high luck value and the bonus of reducing the surgical error rate, similar situations can be basically avoided."

"Teacher, basics?" Ji Xiang accurately grasped the key points in the system NPC's words.

"Yes." The system NPC gave Ji Xiang a positive answer, "It can only be basically avoided, but it cannot be achieved 100%."

Ji Xiang is a little regretful.

It would be great if it could be 100% free of complications and sequelae.

"The next training surgery is partial nephrectomy and treatment of complications."

"I……"

Ji Xiang looked at the more than 500,000 experience points he had accumulated and already understood the meaning of the system NPC.

"Want to fill up the interventional surgeries?" Ji Xiang asked.

The system NPC did not answer his question, but smelled the white Ganoderma lucidum with fascination.

That's probably it. Ji Xiang didn't feel too worried and was ready to complete the interventional surgery.

Because interventional surgery and urology belong to two different branches, the foundation is weak and we can only start from scratch.

Ji Xiang clicked on the system page, found the Department of Radiology, and clicked to enter interventional surgery.

A row of menu drop-downs.

He glanced at it and saw that hundreds of spells gave Ji Xiang a headache.

"Teacher, which technique should I add?" Ji Xiang asked.

"Vascular Interventional Embolization."

Ji Xiang clicked to upgrade without hesitation.

The new LV9 level interventional embolization appears, and the passive skills given by the upgrade are still the same, but they only increase hand speed, reduce error rates, etc.

There is no active skill like [Superior Doctor's Gaze].

It seems that [the gaze of a superior doctor] should be a benefit given by the system to novices.

"Teacher, I'm fine here."

"Before training, should you feel the same way?" the system NPC suggested.

Partial nephrectomy?

Plus postoperative bleeding.

Ji Xiang is also very curious about this, because the surgery and complications of partial nephrectomy are somewhat different from other surgeries.

Bleeding after this surgery usually occurs very late. Just when the patient thinks he has recovered, a single bleeding may lead to tragedy.

"Okay." Ji Xiang is not pretentious, he just empathizes with his experience. He has a strong will and doesn't think anything of it. Since the system NPC suggested it, he might as well go and feel it himself.

"Follow me." The system NPC's deformed fingers shook slightly, and the white Ganoderma lucidum disappeared between the fingers, as if it was a magic trick.

Ji Xiang knew that the system NPC's hand speed was indescribable, and anyway, he couldn't match it now.

Walking into the next room with the system NPC, the lights and shadows flickered, and Ji Xiang began to feel the same way.

Opening his eyes, Ji Xiang found himself sitting in the consulting room.

Opposite him was a middle-aged doctor, talking to himself.
Chapter completed!
