"So, you transformed into Kasumigaoka-senpai and came to school because you wanted to meet your sister?"

Yan Kai listened to Eve's brief explanation of her situation and purpose. He was silent for a while, then stretched out his hand to Eve.

"Please give me your hand."

Yan Kai said to Eve.

Eve hesitated for a moment, but still stretched out her hand - she thought Yan Kai wanted to shake hands with her.

Unexpectedly, Yan Kai did not shake hands with Eve, but gently held Eve's wrist and put his middle finger and index finger on Eve's artery.

When Eve was wondering, Yan Kai put his ring finger on her again.

Yan Kai remained motionless for a while, then let go of Eve's hand and asked Eve: "In the past year, have you felt very weak every once in a while, like

That feeling of your whole body being empty?

Eve was shocked. This was her secret. She had never told anyone about it. Even Shi En and Tuo Lei didn't know about it. Occasionally, when an illness was discovered, she was put off by her. Now it was revealed by Yan Kai.

She didn't know how Yan Kai found out, but she nodded quickly and said, "That's right."

"Are the intervals between attacks getting shorter and shorter?"

Eve nodded again.

"As expected..." Yan Kai touched his chin and said "As expected", but did not say the next words, which made Ryoko Mikado anxious.

"Kaijun, what happened to Eve? You should finish your sentence!"

Ryoko Mikado urged, she majored in modern medicine, but she also knew the wonders of Chinese medicine, and also knew that Yan Kai had a strong foundation in Chinese medicine. Chinese medicine had the miraculous ability to detect diseases without using tools. Yan Kai

Kai must have seen something wrong with Eve's body.

"Call Teacher Tiayu over first. It will be easier for you all to listen to these words together." Yan Kai said to Ryoko Mikado, then turned to face Eve, "You must miss your sister too, right?"

"Yeah!" Eve nodded desperately.

She really wanted to die.

Tiayu was quickly called by Ryoko Mikado. She opened the door of the infirmary and complained: "Ryoko, why are you calling me here all of a sudden? I'm still in class here..."

Ryoko Mikado just told Tiayu that she had something to come to see her, but deliberately did not say what it was. This was mainly because she was afraid that she would run over anxiously after knowing that the sister she thought about day and night was here, and then fall and bang on the road.

, so she will probably be carried to the infirmary on a stretcher.

Although this can achieve the goal, it is too time-consuming and physically demanding, so forget it.

Tiayu's complaining words stopped abruptly when she saw Eve. Tears instantly filled her big green eyes. She covered her mouth and couldn't believe what she was seeing now.

"E...Eve!"

Tiayu finally yelled and rushed towards Eve with all her strength. It didn't matter if she was dreaming, she still wanted to keep her little sister's little body tightly and refused to let go.

"Eve! Eve! Eve..."

Tiayu burst into tears and poured out all her thoughts about Eve these days.

elder sister……

It was a little uncomfortable to be held by Tiayu, but the familiar and warm embrace made her reluctant to push it away. She stretched out her little hands and wrapped her arms around Tiyayu, hugging her sister.

When Tiayou's crying subsided, Yan Kai said calmly: "Teacher Tiayou, I'm sorry to disturb your sisters' reunion, but I have something very important to say now. Please listen to it."

Tiayu nodded, let go of Eve, pulled the corner of Mikado Ryoko's unbuttoned white coat and wiped her tears and nose, then took out a handkerchief to wipe the tears and nose she left on Eve.

go.

I……

Mikado Ryoko had a lot of things to say mmp, but considering that Tiayu's sisters had just reunited, she thought it would be better to wait until night to deal with this heartless girl.

"First of all, Eve is now wanted by the underground world. There is a reward of one billion US dollars, which is quite a lot."

Yan Kai organized his speech and said to Tiayou.

"Ah, isn't Eve very dangerous?" Tiayo hugged Eve tightly again. Her most precious sister was lost and found again, and she couldn't bear the pain of being lost again.

"This is just a small matter, don't take it too seriously. Let me talk about the important things first." Yan Kai found a chair and sat down, and said calmly, "The most important thing now is that Eve's lifespan... seems to be short."

"She doesn't have a long lifespan? Why?" Tiayou tightened her arms around Eve. She didn't have a long lifespan. How could this be allowed? She had just found her sister, and she couldn't let her sister leave her again.

Yan Kai found a piece of paper and a pen, used the pen to draw a rough outline of the human body on the paper, and then used a dotted line to draw a circle in the human body.

"Let me explain it to you intuitively. You can understand this circle as vitality. It is not an organ of the human body, it is just a general concept."

Yan Kai added a thin stroke to each gap in the dotted circle, making it look like the dotted circle is emitting something from the gap: "What flows out of the circle is life force, and anyone's life force is flowing away.

Yes, this cannot be changed. People with advanced martial arts skills can slow down the speed of this passage, but in the end they cannot stop this process."

"And the life force that flows out can be left in the human body in various ways to become a force that can be used by people instead of wasting it in vain. We in the Central Plains call this force internal force, true energy. People in Tianzhu call this Chakra. In Europe

People call it ether, and everyone has their own name. For the convenience of research, my grandfather collectively called them life energy, which is convenient to remember and understand. The theory that discusses the use of this energy is naturally life energy science."

"Who is your grandpa?" Eve was the only person here who didn't know who grandpa Yan Kai was. From what Yan Kai said, it seemed that Yan Kai's grandpa had a lot of knowledge about these things, so she couldn't help but ask.

"Yan Yun." Yan Kai replied casually.

"..."

Eve immediately kept silent. She knew Yan Yun. Although Yan Yun did not appear in any textbook, he was an undisputed super master.

At the same time, Eve also understood why Tiayu and Mikado Ryoko believed in Yan Kai’s words so much. Although tiger fathers can also have dogs, Yan Kai’s family background will naturally make others trust him more. This is the nature of human beings.

It’s normal, and it’s true at all times and in all countries.

"Generally, people who practice martial arts practice to absorb the emitted vitality and convert it into internal force. Depending on the quality of the martial arts learned, the strength of one's own physique, the efficiency and conversion rate will also be different."

"And there are some warriors who know very well that they can't reap the benefits. When practicing, they will not only absorb life force and convert it into internal force. At the same time, they will also use the internal force to warm the body and feed back the life force. This is the so-called strengthening the foundation and cultivating the essence.

A martial artist will not practice too fast, but his foundation is very solid, and he will generally live longer than others... Well, as long as he is not beaten to death on the way. Such people call themselves Xuanmen authentic sects in the Central Plains, and most of the famous sects

They are all this kind of people.”

Seeing how Tiayu and Mikado Ryoko looked thoughtful after hearing the word "honest family", Yan Kai added: "I'm talking about the real noble family, not the ones I drew in the comics."

Tiayu and Mikado Ryoko nodded repeatedly, yes, that's right, they are those guys.

I don’t know what Tiayu and Ryoko Mikado are nodding to, but Yan Kai continues: "There are two sides to things. Some people like to take a long-term view, but there are also people who are eager for quick success and believe that ten birds in the forest are worse than one in the hand. They not only

Those who practice kungfu restlessly and do not provide feedback, instead blindly squeezing their vitality to enhance their kung fu. No matter how quickly these evil martial arts enhance their kung fu, they will also affect their xinxing... Well, just think of it as affecting hormone secretion, anyway.

After practicing, it is easy to develop various mental illnesses, and these warriors are the so-called evil sects and crooked ways."

"I see, is that why the Demon Sect was besieged by the eight sects?" Tiayou suddenly realized.

"Uh..." Yan Kai moved his mouth. He had a lot to say, but in the end he nodded, "You're right."

Although the demon sect in the comics is not like this, in the history of the Central Plains, the reason why famous sects and the demon sect are constantly fighting is because of this. After all, any normal person will panic when he sees a group of mentally ill people getting together, so he will hurt himself if he is a group of mentally ill people.

It was reasonable to kill the opponent first. After all, at that time, the law did not protect the mentally ill.

"Okay, let's be serious." Yan Kai pushed up his glasses and continued to explain, "Don't think that you are the only one who is researching the technology of quick warriors. The Central Plains has been full of such people who want to take advantage of the situation since ancient times.

There are more or less, and the evil cultivation method I mentioned is one of them, squeezing life force and converting it into internal force. However, this cultivation method will not only make people insane, but also greatly reduce their life span."

"A bucket has 400 liters. Originally, one liter of water flows out every minute, and it takes 400 minutes to finish. But if two liters of water flow out every minute, it takes 200 minutes to finish. The time it takes to flow water is the life span."

Tiayou quickly understood the meaning of Yan Kai's words: "You mean, Eve's current situation is the same as that of those who practice evil martial arts, and their life span will be halved?"

Yan Kai shook his head and added a few more strokes to the circle representing vitality, until the circle turned into a circle with a hole in it.

"Aren't you increasing the water flow? You are opening a big hole at the bottom of the bucket." Yan Kai picked up a glass and asked Mikado Ryoko first, "Is it okay if it's broken?"

Of course Ryoko Mikado wouldn't mind, nodded in agreement, and let Yan Kai do with the cup as he pleased.

Yan Kai nodded, breathed out from his hand, and the bottom of the glass suddenly broke into pieces like cotton wool.

Pick up the kettle and pour water into the water glass with a broken bottom. Without any accident, the water slowly seeps out from the crack in the bottom of the water glass downwards.

Yan Kai pointed at the seeping water cup and said to Tiayou and the others: "This is Eve's current physical condition. She is like this cup with a leaky bottom, but what flows out is not water, but life force."

"How is that possible!" Tiayou was shocked, "I know that kind of surgery will cause great damage to the human body, but the nano-organs I developed can create nano-robots to repair this kind of damage at the cellular level. Why does this happen?

kind of thing."

"Your nanorobot..." Yan Kai thought for a while and put a piece of paper at the bottom of the cup. Because of the obstruction of the paper, the water stopped seeping out temporarily, but after the water completely soaked the paper, the water again flowed from the bottom of the cup.

ooze.

"The function is probably the same as this piece of paper. It works temporarily, but it will definitely not work in the long term." Yan Kai explained, and drank the water in the cup. "The loss of vitality will cause the activity of cells throughout the body to decrease, which is equivalent to

Premature aging is a change that cannot be repaired by nanorobots. Nanorobots can heal sick and injured cells, but they cannot prevent a cell from dying and going to bed."

"What should we do!"

Tiayu's whole heart twitched. If her most precious sister was killed because of her research, she would never forgive herself for the rest of her life.

"Sister." Eve put her hand on Tiayu's cheek to comfort Tiayu. It was not Tiayu's fault that she became like this. Instead, it was because of her that Tiayu was forced to study those evil things.

Technology, she was the one who dragged down Tiayu. She didn't want to make Tiayu sad, but she didn't know what to do.

"It's okay, this can be fixed."

Yan Kai said calmly.
