The skill of chasing teeth, KKX uses white teeth, and the most powerful skill of white teeth is "white light reproduction", which can destroy all covered things. During the war, Baiya destroyed the whole Douguo with this technology, and he also used white light to breed and killed more than 100 people. In kakashi gaiden's original work, after the white teeth were lit by Qinglong, chakra was only less than Kyubi no Youko, and his knife skills were really good, which were found in all the weapons and moves of Konoha. But he attacked from all sides and defended from all sides. With so many chakra, he seldom used his vitality. However, when Neiguangji took revenge for the first time and joined six attacks on Konoha, Baiya beat them back with vitality and endurance. At that time, Liudao had told Neiguangban to be careful of the white flag-white light dance, which showed that Qi Mu's saber was still very strong.
