MTL - The Venerable Swordsman - Chapter 46 : Crashing the mountain!

A man reincarnates in the body of a boy who suffered a tragedy, only to realize that he is in the world of My Hero Academia. What's even stranger is that his quirk seems to have the abilities of Nen and Haki.

Originally, the question Tang Xian was thinking about was whether he should be a hero for a second among this group of destructive bosses, or continue to pretend to be a boss.

Later he found out that if you pretend to be fake, it becomes real.

What do you do when your brother dies because of some entitled assholes? You go undercover.My real name? Clare. But at school, I’m Clause—just another guy blending in. Disguised. Watching. Yes, a boy. No, it's not an all-boys school—I'm just deep undercover, hunting down the bastard responsible for my brother’s suicide. Nobody—and I mean nobody—messes with my precious brother and gets away with it. They better pray I never find them, because when I do? Death will be a mercy, and trust me—I don’t do mercy.And as for the egotistical Alpha and the narcissistic Vampire Prince? They can go fuck themselves. I don’t do mates, I don’t do claiming, and I sure as hell don’t do them.

I belong to a good sect that has never turned its back on me for my poor potential, has never forced me to study martial arts, and even helped arrange a betrothal for me when I was young.

My fiancée is a much renowned hot-tempered young miss. She’s beautiful, strong, and deeply loves me. Upon my start down the path of the Jianghu, I entirely relied on her to provide cover for me and before long, I became renowned as the #1 Pretty Boy of the Immortal Path.

Yet one day, I discovered that this person is apparently a man. A man in drag!

More unforgivable is that he thought I was a woman dressing as a man!

Me, as if my liver and guts are being cut to pieces: “Brother, what have you done with my fiancée?”

Him, as if a knife has been twisted in his heart: “Brother, what have *you* done with my fiancée?”

The waters of the Jianghu are indeed murky. Even if I am starving, even if I’m dying far from home, from this point on, I will not eat even a mouthful of rice prepared by him.

—So fragrant.
