Eighteen-year-old Lin Mo has endured three years of school bullying for being fat and ugly. On the eve of transferring schools, he unexpectedly gains a second body: one that's handsome and perfect. But it comes at the cost of his lifespan. Every time he uses it, the ring around his wrist loses one segment.
He uses his handsome body to experience what it's like to be respected, and works odd jobs in his original body to understand the hardships of ordinary people. After meeting his hot-blooded brother Jiang Chen and strategist Han Zhao, the three form an ironclad trio and get caught up in a struggle between four underground factions. The organization behind it all, “Gene Tower,” emerges from the shadows. Lin Mo's two bodies turn out to be the result of a human experimentation project his father took part in, and as the sole perfect specimen, “Number 000,” he is being hunted by the organization.
From fighting back at school to battling for control of the underworld, from underground fight clubs to the global “New Era Project,” Lin Mo must join forces with his companions to destroy the dark empire that creates modified humans before his countdown to death runs out. What he learns isn't how to fight, but how to protect.
Jiang Chen loses an arm saving him, Zong Jian switches sides to atone for his sins, Jin Jiaolong spends the rest of his life passing on his convictions, and Ye Xuan betrays him only to win his trust... Along the way, Lin Mo discovers that true strength lies not in one's appearance, but in kindness and courage.
When the last segment of the ring around his wrist disappears, he chooses to give up his warrior body and return to being an ordinary husband, father, and researcher. Using the notes his father left behind, he cures countless modified humans and helps create a world that no longer judges people by their looks.
This is a passionate story about discrimination based on appearance, class divisions, sacrifice, and reconciliation. It is also the coming-of-age epic of a person learning to accept himself and become someone better.
