First Immortal of the Sword - Chapter 16: Just Don’t Do it Again

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.

In the current era, people are either normal or are with ‘special abilities’. Cases related to the latter are managed by the “National Anomaly Prevention and Control and Special Species Management Office”.
Qi Zheng Emperor Sheng Lingyuan was reawakened a thousand years later after he jumped off the fiery Red Lake. Xuan Ji, a newly transferred staff to the Reparations Division of the Deviant Control Office, finds himself having to clean up the mess of a revived tyrannical monarch. The two seemed to share something from the past, but unbeknownst to them, a big conspiracy is stirring right underneath their noses that could destroy the balance of the world.

Three years ago, the animals and plants on Earth underwent crazy and unexplainable changes that included transformations, reversions, and the addition of otherworldly species. And it was the start of a brand-new type of profession in the new generation of humanity – Monster Trainers, people who specialized in taming monsters.

Cen Shuang used to be the daughter of a wealthy family. After she fell from grace, she was forced to bend her back just to make sure she had enough food. She was sold by her uncle for 10 million to the wealthy Zhuang family as the bride that would counter the bad luck in the Zhuang family.

She married Young Master Zhuang, who went into a comatose after a car accident. Everyone viewed the marriage between the fallen daughter of a once rich family and the comatose young master as ridiculous.

The socialites who were once under Cen Shuang’s feet were all waiting to see Cen Shuang make a fool of herself. Unexpectedly, on the night of their wedding, Zhuang Hong, who was in a vegetative state, suddenly woke up.

Cen Shuang instantly transformed into the Zhuang family’s benefactor, and the Zhuang family were extremely protective of her as they doted on her. Grandpa Zhuang asked, “Lil Shuang’er, do you want a black card?”

Mr. Zhuang asked, “Lil Shuang’er, are you bored staying at home all day? Should I give you a company to toy around with?” Mrs. Zhuang said, “This is the newest season’s haute couture. Throw those in the last season away since you’ve already worn them.”

Zhuang Hong, “Nothing about my wife concerns you!” From necessities to food and accommodation, the man did everything himself and spoilt Cen Shuang to the extremes.

Outsiders were jealous of Cen Shuang’s good fortune, but little did they know that this joyous occasion had been long premeditated. Zhuang Hong, “A single look lasted for ten thousand years. After many twists and turns, I finally married the girl I like.”

Cen Shuang, “I thought that there will only be darkness in my life, but there’s a silver lining waiting for me.”
