Shocking! This Konoha Chunin Knows Observation Haki

Other people transmigrate with a System. I transmigrated with a door.

The moment I opened it, a Sea King bigger than a mountain was waiting on the other side. I almost died on the spot!

Su Yu was stunned. What the heck, was this the world of One Piece?!

Can't understand the language and get robbed by pirates? Hit them back with a Great Fireball Jutsu!

The Marine hero Garp is escorting a Devil Fruit? Trade him Konoha's specialty soldier pills. That's what you call cross-dimensional commerce!

From then on, Su Yu charged ahead on the road to becoming a “dimensional trader.”

Back in Konoha for the Chunin Exams, a Hyuga prodigy activated his Byakugan and confidently tried to strike his chakra points.

Su Yu covered himself in Armament Haki. “Your chakra-point strikes can't even get through my Iron Body!”

In the world of One Piece, Logia users smugly assumed they were immune to physical attacks.

Su Yu hit them with Water Release: Great Waterfall Technique and taught them a lesson. “Sorry, but there are no absolutely invincible abilities where I'm from!”

Then one day, Uchiha Madara watched Su Yu predict every move he made and fell into deep thought.

“Is your ability to predict my movements some kind of ocular technique that surpasses the Sharingan?”

Su Yu smiled. “No, it's called Observation Haki. I don't need my eyes.”
