Three years ago, two months before the end of the world.

A nationwide public welfare campaign has emerged: "Finding the missing younger brother."

The missing younger brother had a stunningly handsome face that rivaled any celebrity, and his misty blue eyes were captivating and beautiful as he looked at the camera.

During that time, everyone called him the nation's little brother.

Every day, people upload photos of boys resembling those in the photos to the official account, partly to gain fame, given the widespread public attention the incident has garnered.

The second one, to put it bluntly, is for the ten million reward.

This "national younger brother" must be from a very wealthy family. As soon as the charity event was launched, he made it clear that as long as someone finds his brother, ten million will be immediately deposited into his account.

With such a generous reward, countless people are actively searching for the nation's little brother.

Yi Mu, who works at a duck shop, has to keep up a facade.

Although he used to be good-looking, he didn't like to dress up.

After this incident, he styled his hair into curls, applied black powder to his face every day, and worked hard to build muscle, transforming himself into a sunny and healthy young man.

For almost half a year, no one recognized him.

When the apocalypse came, no one paid any more attention to the charity event, and Yi Mu breathed a sigh of relief.

The old man in front of me, with a typical grandfather's face, was the deputy of the freakish genius scientist who was in charge of Yi Mu's physical research back then.

He was just like that madman who experimented on Emu, passionate about the science he talked about.

They get so excited that they can have an orgasm on the spot if the experiment yields even the slightest result, completely disregarding the fact that the experimental subject might explode and die in the next second.

Yi Mu only regretted that he hadn't met this old man when he escaped back then.

Otherwise, he would definitely have injected all those viruses that make people wish they were dead into his body, so that he could also experience what it's like to be worse than dead.

Yi Mu didn't come here to walk right into a trap.

He finished the last bite of his apple, carefully wiped his hands with a tissue on the table, and said casually, "I came here not so you could put those tubes back into me."

The old man smiled, his face displaying an annoyingly confident air.

"That's not up to you. Even if you are a precious first-generation immune person, you can't be the exception. Being arrogant won't work here."

These words stunned everyone present.

It's important to know that there's only one immune person in the world right now. Recently, news came from the Americas that their immune person couldn't bear the pain of the experiments and committed suicide by cutting their wrists.

In this way, the original number of immune individuals—one elderly person and one child—is reduced to one.

Now, another immune person has been added, one of whom is Yimu, who has been living with them day and night for half a month.

Pan Wu looked astonished.

The experiment was so inhumane that if it had been exposed, the consequences would have been unimaginable.

The people in the laboratory thought that it wouldn't be too immoral to pull out those heinous criminals from prison and use them for experiments.

That critical juncture was precisely when Xiang Qing and Yi Mu were at the height of their affection.

Yu Die appeared calm on the surface, but in her heart she was filled with murderous hatred.

She accidentally saw the top-secret document in Xiang Qing's office, struggled with her thoughts for several days, and then sent an email to her father.

Soon after, the Xiang and Yu families sent people to the prison and arrested Yi Mu.

Pan Wu knew about this, and he also knew that Yi Mu had escaped in the end, but he never expected that Yi Mu would become immune to the virus after being poisoned by it for half a year.

Xiang Qing was equally surprised; his expression was the most incredulous and complex.

His eyes held shock, heartache, and a hint of joy.
