I Became An Immortal On Mortal Realm - Chapter 440 - 437 Tai Cang Order

He was The Greatest Talent in the Nine Hells Realm.

Shen Zhenyi began to practice his sword when he was four years and two months old.

At the age of seven, he studied the Ten Thousand Sword Sutra. By the age of eleven, he fought against the Yudao in Shangqing Palace. In an instant, he unleashed one hundred and eighty-five sword strikes, making it impossible for anyone to retaliate. The Yudao admitted defeat and deemed him as “The Peerless Genius.”

At the age of 14, Shen Zhenyi, with his Six Forms of the Ancient Sword, surpassed the swordsman Zuo Tianxing who was ranked among the top ten masters in the world, and won the title of “The First Swordsman of the Abyss.”

He now lies crippled. A fraction of the state he was in before. Or so they thought.

- Description from Novelupdates

At the beginning of the universe, there was only chaos. Chaos gave birth to a world, accumulating into Black and White and the five elements (also known as the Origin Elements), creating the world's laws and the order of heaven and earth.

This world was called the Origin world, where the Original beings born out of chaos reigned. They created orders, creatures, and numerous worlds where they reigned as Supreme beings until a calamity befell them and destroyed the Original world alongside numerous worlds.

Two billion years have passed since then. In a small world somewhere, a baby was born carrying an unusual past.

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...

Waking up, Kim Hajin finds himself in a familiar world but an unfamiliar body.
