MTL - Warship of Great Power - ~ extremely depressed

A modern-day antihero, who was infamous for his devious acts, dies in an explosion meant to take down a powerful criminal syndicate. Waking up in a world of sword and sorcery, he finds himself possessing a fragile, powerless body with a strange “System” that seems broken. Initially thinking he's doomed, he learns that by pretending to be weak, he can manipulate others into revealing their secrets, granting him abilities they possess. As he rises in power, he discovers that the System was intentionally sabotaged—by none other than his own future self.

Lu Shang picked up a dirty teenager while discussing work at a bar. It was merely happenstance, but memories from ten years ago resurfaced when he saw the gunshot scars on the teenager’s back.

Lu Shang asked him, “What is your name?”

“Xiao Li… My surname is Li, so they all called me Xiao Li.”

“You don’t have a name?”

“I don’t remember.”

Lu Shang said, “Then I will call you Li Sui. From now on, you will be with me.”

From that day onward, a young “lover” was always by Lu Shang’s side.

Years later, Dr. Leung teased Lu Shang, “You didn’t get his heart, instead your heart caved in; boss Lu, that doesn’t seem like a bargain.”
