MTL - Harue Kagetsu - Chapter 146

Zhou Yu was ordered to enter the city and get married. Even though my wife didn't like me, my father-in-law disapproved of me, my colleagues always wanted to bully me, and the bad guys were always looking to take me down, but touch me, that's fine, touch my wife, that's not. Whoever lays a hand on her, I'll take down. I fought until the whole world bowed down, then returned to the village with my wife in glory!

The main character is reborn as a character from a game he played in his previous life. This character falls into ruin along with the villainess, spending the last of their years together. A man named Kururi Helan.

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.
