Start with the Hokage's One-Hand Seal

Hokage, I can perform seals with one hand, perform taijutsu with one hand, and perform ninjutsu with one hand without any problem. Pirate, I swing my sword 30,000 times a day. Although I haven't become bald, I'm already strong! Douluo, I can swallow and advance, and a fox with one tail becomes a nine-tailed fox to catch up with the enemy. Fighting is broken, I will directly transform the fighting energy into the sky and create a new century overwhelmingly. (Others are yet to be determined.)
