"Officer, I have a report! A senior high school student named Lu Yun from Hongcheng No. 2 High School is illegally buying and selling kidneys!"

Inside the interrogation room, Chen Weihua, an organ trafficker who had just been arrested and imprisoned, had barely sat down when he began to report and expose others.

Police raided and arrested Lu Yun, and interrogated him:

"Your father needs a kidney transplant, so you buy a kidney to save him, but do you know that this is a crime?"

Lu Yun: "I used a kidney cloned from my father's cells. May I ask which law I broke?"

Soon, a DNA report was released.

[The kidney gene sequence matches Lu Yun's father's 100%; the source is legal!]

The police were all dumbfounded.

It turns out that Lu Yun had already gained the ability to "absolutely control the body" and deciphered the secrets of the human body.

Kidney cloning is just the beginning.

Conquering cancer, developing superhuman armor, reversing aging, developing meme technology, and evolving into superhumans... will all be realized.

When Lu Yun's superhuman evolution serum caused the entire population of Dongda University to evolve, countries like the US were completely dumbfounded: "We're still on Earth, how did the entire Dongda University population evolve into superhumans?"

Countries rushed to appeal: "Mr. Lu, science has no borders. Please open up your technologies such as organ cloning, gene evolution, superhuman armor, rejuvenation, and superhuman evolution."

Lu Yun: "Sorry, scientists have national borders."
