Li Zhi, male, born in 2027, is from Danyun City. Pen %Fun Pavilion www.biquge.info No. 104, Jiudong Lane, Jingshui Street, Yonghe District. In 2045, Yonghe graduated from high school with excellent grades and went to the United States to study

The electronic file is flipped back page by page along the timeline until it was recorded thirty years ago. After obtaining the DNA on the original kidney organ from Ryo Kadokura, Ding Yi hacked into the police station's emigration record file. All this is as simple as no man's land under the operation of the cage core. Ding Yi quickly consulted a large amount of population information in Danyun City, compared the DNA of population information, and finally found clues about free radicals.

Although the genes of free radicals have undergone essential changes. But the kidney that belonged to him still retains its original genetic characteristics and has not been assimilated. Since 2025, with the popularization of gene technology, all newborns in Tamyun City have left DNA information and recorded it in the archives. Thanks to this, Ding Yi found the true identity of free radicals.

Behind the cold, gloomy high-rise buildings is a low-rise old residential area that has been blocked from the afternoon sun. There were several large dog barks at the intersection. Between the barber shop and the jewelry shop that opened at the intersection, there is a closed shop that says high-priced recycling. There is only a handwritten mobile phone identification code on the roller shutter. Behind the high-priced recycling signboard, there are a few small blurred letters and a few small circles that twist and turn in scribble. Ding could read that it was a code word commonly used by drug dealers, a simplified molecular writing method of Chinese. Their recycling, of course, is also a prohibited method of recalling a prescription drug, which is used for the illegal extraction of prohibited ingredients in prescription drugs.

According to Ding Yiyi's familiar understanding, these are the downstream ends of the entire prohibited biological products trade in Danyun City, and small fish and shrimp are capable of doing business. No technology, no patents, no funding. It is a scavenger in the biotechnology garbage heap who can only extract the little remaining pitiful surplus value from the residue of biotechnology after the bigwigs are gone. Poverty, hardship, lawlessness.

"104 Jingshui Street? Is it in the wrong place? Wen Ying navigated according to the map, and she saw a bundle of tattered integrated optical fibers hanging in front of the iron door of the unit building marked with the house number. It looks like it's been a long time since there have been any human footprints here.

"There will be a lot of surprises in Danyun City." Ding Yi has long been accustomed to this kind of mixed architecture. "There's no mistake, this is it. It has not been relocated or renovated, this is his home, where free radicals set off. Ding Yi walked up the crumbling spiraling staircase. The corridors are covered with information portals for various underground transactions. Prohibited drugs, ** transaction information, gun buying and selling. There are also world-weary graffiti paintings. When Ding Yi walked through the third flight of stairs, through the gap in the light between the two tall buildings in the distance, Ding Yi saw an open-air circular football field viewing platform. It used to be the alma mater of free radicals -- the only place where children in the slums could change their fate.

The sound of footsteps was particularly heavy on the old staircase, as if it would collapse the staircase. The brick wall does not have any sound insulation function, but only amplifies any movement and quiet. The voice drew a disheveled girl. She curled her hair messily and glanced through the crack in the iron door. Ding Yi's professional habits have long been aware of her intentions. She's just a guy who comes out and takes the lead. Even with his nose, Ding Yi can guess that there is a group of addicts who have given up their studies, even if they are still children, but in the slums, the future is already doomed. As a part of the society of Danyun City, it is like a huge whirlpool, all the ascent is reduced to nothing, and it is dragged downward by the huge gravitational pull of the social testing ground.

Ding Yi knocked on the opposite door, and the iron bolt on the door opened a crack. Seeing that Ding Yi and Wen Ying don't look like debt collectors. A sharp middle-aged man in a jacket opened the door.

"Who are you?" He stopped at the door, curly gray hair.

"Reporter." Ding Yi casually made up an identity. "May I ask Li Zhi, is it here?"

"Who?" The middle-aged man glared at him.

"We are reporters for Southern Tech. I want to find Mr. Li Zhi, whose recent research results can be described as a star of tomorrow, and will definitely bring a sensation in the future," Wen Ying tacitly agreed.

"He's dead!" The man suddenly turned angry and slammed the door shut. "If he's not dead, tell me where he is, and I'll kill this rabbit with my own hands!" He added angrily through the door. "It seems that Mr. Free Radical's popularity is not very good." Ding Yi only woke up after eating the closed door.

"What the hell is he doing here that would attract such hatred." Wen Ying shook her head and said curiously.

"Who knows, but this must be the free radical, his home. Even his old son didn't want to see him. Ding saw the sunset in the west, and his life was sad. Free radicals, he's a complete slum kid. Ding Yi can imagine the trajectory of his life after he was born and before he has the ability to change himself.

"He's a son? Are you saying that the man just now is the father of free radicals? How do you know? ”

"Dominant inheritance, and appearance parameters demonstrate a 997 probability of proving that he has a genetic fit with free radicals."

"You mean, Li Zhi, he really won the award?" At some point, a fat woman leaned on the staircase, smoking a cigarette and wearing slippers, looking pleasant, and asked with great interest.

"Do you know Li Zhi?" Ding Yi and Wen Ying exchanged glances and asked happily.

"Come in." She picked up her cigarette and pointed to the open door downstairs.

"Li Zhi, he's a very smart kid." On the niche is a statue of Kannon. The layout of the room is small, like being in a depressing box. On the wall is a cover poster of the legendary biohacker, Greenpan's youth. This woman is the aunt of free radicals. Since having a stepmother, free radicals in his teenage years have been raised by his aunt for most of the time.

Ding Yi picked up the photo frame, and the free radicals in his youth were very thin and weak, like a malnourished child.

"He had sepsis since he was a child." The woman shook off the match and continued to light the cigarette. "But I'm sure he won't die because of it. This kid is tenacious. Heaven has given him such a clever head, and he will definitely not take him away so early. Although I haven't heard from him for a long time, with today's biotechnology, any disease can be cured, isn't it? ”

"He said he wanted to go to the United States, and one day, he was going to meet this person." The woman gestured to the American on the wall
