At 79, Adom is an old mage who has known nothing but illness and regret. When the world finally burns and all hope turns to ash, at the last beat of his fading heart, a mysterious being appears in the dimming light with a simple question:“If you could try again, would you?”What's left to lose when you've already lost everything?A handshake seals the deal, and Adom wakes up on his old school grounds, sixty-seven years in the past. When everything is still possible. A second chance with all his knowledge intact, his memories preserved, and his youth restored.This time, Adom wants it all: to feast on food he's never had, to travel a world still full of wonder, to finally live the life he dreamed of. There's just, as always, one small catch—he needs to prevent the end of the world first.But as Adom will soon discover, changing history might demand sacrifices even greater than watching it burn...

The worst and strongest villain.I became the narrow-eyed character Arsene Adel.“Revenge.”It sounded good.At least to the original owner of the body.But from my point of view, the goal is not revenge, but survival.I didn’t have the confidence to survive among humans, soㅡI went to the Demon Realm.Where I was headed,A school for demons that is said to be attended by the children of prestigious families in the demon world,……It was a school that terrorized the human world.

After the failure of crossing the tribulation, Ye Leng’an returned to the first life again.

In that life, she was the fake daughter of the Ye family who shouted and beat her. Against the background of the real daughter, she was like mud under the ground, while the other party was the bright moon in the sky. In the end, she died tragically under the pressure and frame of the real daughter’s admirers, and her fate was bleak.

After her death, her soul traveled to the world of comprehension. With hard work, she finally reached the stage of crossing the catastrophe, only one step away from ascending to immortality. But when crossing the catastrophe, he failed because of the inner demons of the first life.

In this life, she came back with thousands of splendors, and she was no longer the wimpy and fake daughter she once was.

Hehe, after living a new life, she wants to bloom her own brilliance, gods block and kill gods, and Buddhas block and kill Buddhas.

The real daughter is a medical genius with the potential to become a genius doctor?

Excuse me, the originator of life and death is here, holding a panacea in his hand, attracting countless bosses to compete!

The real daughter is a computer wizard, but she can freely shuttle through the Internet?

I’m sorry, but the network she developed has come and gone. In her network, she is a god, killing with one thought.

The rebirth of a great power in the comprehension world has set off countless storms in the city.

Just when countless bigwigs were falling for her, a mysterious man with huge power both in the open and in the dark embraced her directly and swore sovereignty: “This is mine, wife.”

At this time, Ye Leng’an could only helplessly roll his eyes to the sky: He really is a jealous guy!
