Like most candidates, Zlatan's dream was a simple one. To pass the hunter's test, join a guild, hunt monsters and reach the A-class.Eventually, as he dreamed of, he achieved it hundreds of years later. Having sacrificed more than he could take in, using the most unthinkable and brutal measures, he became an S-class Hunter instead.Obtaining the Copper Flame back then after the Aura Awakening Ritual, that was his greatest flaw. Taking a span of 80 years to reach a D-class. Still, Zlatan Elmore became the most powerful hunter to exist.Falling on the battlefield against a Two-horned Dragon, he suddenly awoke as his 30 year old self. Given another chance at life, he didn't only have his memories but he's also given a Blank Scroll. This mysterious scroll doesn't only speak, its omniscient!

In his previous life, An Ji seemed to have the word “unlucky” written on his forehead.

He was born into nobility, but ended up living on the streets for ten years. He found a beta boyfriend, but the scumbag tricked him into cutting out his glands. He dedicated his life to the omega cause, but ended up dying without an intact corpse.

It wasn’t until later that he found out that everyone described people like him as “beautiful, strong, and tragic.” The difference was that the beautiful, strong, and tragic characters in stories all have happy endings, but he only got death.

An Ji: “WTF.”

Then he is reborn.

In this second life, An Ji expresses that he will only be beautiful and strong. As for tragic? f*ck that shit!

But can someone tell him why his previously polite fiancé suddenly changed personalities?

Star history states that Emperor Rongwu had a brutal nature and outstanding ability. He ruled with an iron fist and created a prosperous world that lasted for hundreds of years after the war.

Everyone thought that he was too focused on his career to spare any attention for love. Very few people knew that he was always thinking about his fiancée, the true love that he let get away because of his ridiculous notions of kindness.

The great, unmarried emperor ended his long and lonely life after choosing a successor for the throne.

When he opens his eyes again, Li Rong has returned to his youth.

The young puppy Li Rong believes that if you love someone, you must give that person freedom.

The old dog Li Rong says that is all nonsense. If you love someone, you must possess that person at all costs.

Much later on, An Ji rubs his sore waist and thinks that his new life is still tragic to some extent.

The young puppy and the old dog come in turns. Even the strongest omega wouldn’t be able to stand it… ORZ
