Yukira stiffened. He remembered the conversation he had with Jinhai that day in the office, where he told the truth about Huian.
After that day, Yukira thought about it a lot. The desire to become strong like Jinhai took root in his heart. He also wanted to protect Nana, just like Jinhai did.
First, his father, Yu Tengfei, had harmed her, then Suyin came trying to ruin her, and then Huian hurt her too. And now Yukira didn't want to be a weakling anymore.
Not only that, something about the underworld attracted him towards it. At first, that world scared him, but then it made him giddy. He also wanted to be a part of it.
Yukira wanted to learn how to fight. He wanted the strength in his hands and legs to protect the ones he held dear in need of time. The underworld had the power to defeat an enemy in its own way, not relying on the law.
So one day, he went to Jinhai.
"Brother-in-law, I want to train under you."
