Damn Necromancer - Chapter 181

In a world governed by the mysterious power of dimensional gates, young Dabi, once frail but gifted with a photographic memory, discovers his life-altering ability: a leveling system that grants him new skills and magic as he rises through the ranks. After his family perished in a gate-related tragedy, Dabi swears to protect his siblings and unravel the mysteries within these deadly portals. Alongside his loyal spirit pets and rare allies, Dabi faces ancient threats and powerful enemies tied to his parents’ tragic past. As he rises in power, Dabi’s quest draws the attention of noble families, dangerous royals, and sinister forces seeking control over dimensions and the future of humanity itself. Secrets, betrayals, and a growing vendetta lead him deeper into a battle that threatens the fabric of existence. With the fate of his world hanging in the balance, Dabi must outwit and outfight forces beyond imagination all while confronting the truths hidden within the gates of the lost dimension.

An accident let him have a special ability to turn back time up to 1 minute. When he said the wrong things in front of his leader, he was able to return back to 1 minute before to correct what he said. During jade stone gambling and there was no jade inside, he turns back time to pick another stone. When the woman he likes met an accident, he can return back to 1 minute before to save her…… A small fry’s rise through the ranks of the government service starts……

Before going to college, an ordinary high school student went to celebrate and got drunk. When he woke up, he found himself in a completely different world. There was a big sect, the approaching sect entrance examination, a slum where his body’s previous owner lived, and a shared memory about a missing young girl.

When he got tangled in a fight with a few punks in this different world, he fell off a cliff and miraculously found himself still alive, with two more voices ringing inside his head. They were Sword Master and Saber Master. In the company of them, he continued to find out more about this whole new world. He took the sect entrance examination, entered the sect, met a strange man in black, and even participated in a major competition of the sect to have a chance to win over his peers!
In this whole new world, he was born again and got to explore the fantastic martial world!
