"The best disciple?"

Maybe everyone in the world thinks so, Qin Hao is Mr. Wei's best disciple.

But in the hearts of both of them, there is still a person, but the world does not know his existence.

This is also the person they don't want to remember, especially Mr. Wei. This has always been a scar in his heart that he doesn't want to be opened.

His name was Yu Guang, and he was Qin Hao's senior. He was one year older than Qin Hao. At that time, they were both Mr. Wei's favorite disciples.

If Qin Hao's achievements now allow him to shine in front of others like the sun, during that period he could only reflect the afterglow like the moon.

Because Yu Guang is truly a genius. Mr. Wei once described him as saying that he could lead China's medical epidemic prevention within ten years and be at the forefront of the world in twenty years.

Qin Hao was very happy to have such a senior brother, especially since Yu Guang was very kind to him.

He always shared some of his more avant-garde ideas and scientific research experiences with him, which also played a crucial role in Qin Hao's later development.

However, such an outstanding disciple failed to come into front of people because of an accident.

It was the autumn of 2002. One day, Yu Guang's fiancée Li Na felt a little unwell, so Yu Guang asked for leave and accompanied her to the hospital.

The result was very unexpected. At a young age, Li Na actually contracted Pancreas cancer, the king of cancers, and it had reached the final stage.

Even without considering the financial situation, the doctor did not recommend surgery, not to mention that both of them were studying for graduate school at the time, and their family conditions were average, so they simply could not afford the corresponding medical expenses.

Li Na also followed the doctor's advice at the time and chose conservative treatment.

From that day on, his peripheral vision changed. His body no longer shone with light, but became as melancholy as a fog.

Apart from staying with Li Na, who was deteriorating day by day, I spent the rest of my time alone in the laboratory.

At that time, Mr. Wei and others thought that Yu Guang was under too much pressure and had to work hard to find relief, so they did not interfere too much with him.

But Li Na's illness progressed too quickly. Just two months later, she had already lost the ability to take care of herself.

The whole person is no longer as thin as before. The loose skin sticks directly to the bones. If you look carefully, you can even see the connection of each joint.

At this time, Yu Guang was stuck in the laboratory almost 24 hours a day and was not by her side.

Li Na's condition is getting worse day by day, and her consciousness is starting to become blurry.

One day, Yu Guang came back very early and bought a large bouquet of roses. This made Li Na, who had been living in pain, smile for a long time.

Yu Guang cooked a lot of dishes that day, and they also opened red wine. Of course, Li Na basically could only watch and couldn't eat anything.

After dinner, Yu Guang excitedly sat in front of Li Na, holding her hands that were so thin that only bones remained.

"Nana, it's been hard on you these days. I haven't been able to be by your side." Yu Guang's eyes were filled with deep friendship.

"It doesn't matter... you have important things to do, whether you accompany me or not, it doesn't matter. I know you have me in your heart, that's enough."

Li Na forced a smile, trying to make herself look less intimidating.

"Thank you for always supporting me and never complaining about anything. I will always be with you in the days to come." There were a few tears in Yu Guang's eyes.

"Stop talking nonsense, I don't have much time left, so don't waste too much time on me. You will meet a better girl than me in the future."

Li Na's eyes could no longer shed any tears, but they were also filled with sadness.

Yu Guang said calmly: "No, I will not let you leave me. I have found a way to save you. We will always be together."

"We have found a way to save me. Please stop making me happy. I am not a three-year-old child. There is no cure for my disease."

Li Naquan thought she was comforting her out of the corner of her eye.

"What I said is true. Do you think why I have been staying in the laboratory these days is just to save you."

As he spoke, he took out two sealed test tubes from his arms, filled with blue liquid inside.

"What is this?" Li Na felt a little emotional when she saw the blue liquid in the test tube.

"This is a directional phagocytic virus. I gave it a nice name called Fanxing." Yu Guang excitedly held up the two test tubes in his hands.

"Virus?"

Li Na was full of confusion about Yu Guang's answer. In her impression, viruses destroy the human body, so how could he use viruses to harm himself?

Seeing Li Na's doubts, Yu Guang quickly explained his masterpiece excitedly.

"You should know very well about hepatitis B virus. It is a hepatotropic DNA virus, which is a liver-targeted virus.

Targeted viruses, it just destroys your liver."

"And Fanxing is a targeted virus targeting your cancer cells. It only targets your cancer cells."

Yu Guang was very satisfied with his masterpiece and couldn't stop talking about it.

"Do you know how I did it?" Yu Guang's shining eyes asked Li Na demandingly.

Li Na forced out a smile again, looked at her peripheral vision like a child, and said calmly: "How did you do that?"

Yu Guang immediately started talking excitedly again.

"When the doctor said there was no need for surgery, I felt like the sky was falling."

"I couldn't accept this result, so I told myself, since they can't save you, then I will save you myself."

Hearing this, Li Na looked at the man in front of her with some gratitude. He had been silently working hard for herself for so many days and nights.

"After thinking for a long time, I came up with an idea to create something that can destroy your cancer cells."

"In addition to having clear direction, this kind of thing must have strong adaptability and reproductive capabilities."

"The only ones that meet this condition are viruses, so I started to modify the viruses."

"Finally, after countless attempts, I was able to isolate a segment of RNA from cancer cells and successfully implant it into the DNA segment of phagocytes."

Out of the corner of his eye, he subconsciously shook the two small test tubes in his hands.

"Through continuous transformation, Fanxing finally succeeded in surviving and has the abilities we need."

"Through many experiments on animals, it has been confirmed that Fanxing has the ability to phagocytose directional substances and is safe for cells or tissues other than directional ones."

At this point, his peripheral vision stopped, he looked at Li Na affectionately, and said slowly.

"But we don't have time to do more tests, let alone human trials, so I'm not sure whether Fanxing can ultimately do it."

Li Na took out her withered right hand from Yu Guang's hand and gently stroked his face.

"I believe you. Just do what you think is right. It won't be worse than the current situation."

Yu Guang looked at Li Na with tears in her eyes and nodded deeply.
