One Piece - I Am A Different Luffy! - Chapter 473 - 471 - The Wano War 11.

Zhang Ruo Chen was the sole male heir of one of the nine emperors of the Kunlun Field. Ruo Chen’s father was known to all as the “Enlightened Emperor”, however Ruo Chen didn’t just leech off his status as emperor’s son. He proved himself to be a dragon amongst men, possessing a heaven defying body, and managing to cultivate to Greater Perfection within the Yellow Horizon Realm, at just the young age of 16.

But even though he stood at the summit of the younger generation and had a boundless future, he sadly died at the treacherous hands of his own fiancee at a young age.

Reincarnated 800 years later in the body of a young boy who shares his name, he found out his former fiancee already unified Kunlun’s Field and built the First Central Empire, and was now known as Empress Chi Yao… Empress Chi Yao—Her Majesty governed the mortal world and enjoyed prestige in all directions as well as an eternal life.

Zhang Ruochen stood outside of the Imperial Ancestral Temple, looking at the statue of Empress Chi Yao, and the flames of hatred burned in his heart. “After I practice for 13 years, I shall send the empress to her doom!”

After an accidental electrocution, Zhang Yi realized he could hide his body and become an invisible man. That incident marked a new chapter in his life. The magnificent president of the company, the hot policewoman, and the mischievous daughter of a rich man.“Apologies. I'm a righteous man. I've never abused my power of turning invisible to creep on beautiful girls, because I'd only stand boldly before them to look at them! You can't see me. You can't see me. You can't see me…”
