Prove the Tao with Force, Starting from Konoha

Reborn in Konoha, I am Metkai's brother, Yun. Looking at my father who was laughed at and my brother who was bullied, I knew that this world that only recognized blood and talent needed to change. Fortunately, I brought the answer from another world - the physical training system. Chakra? It's not as good as Qi and blood like a dragon! Ninjutsu? I'll destroy it with one punch! I taught my brother how to truly burn youth without regrets, and I told Kakashi that White Fang's sword can be faster too! When the Akatsuki organization came and the Ninja War broke out, I stood in front of everyone. "I will protect my brother, and this ninja world will be pacified by my fists!"
