If You Don't Choose the Four Generals, You Choose Saitama and Goku?

In a parallel world, thousands of races invade and monsters run rampant. After everyone reaches the age of eighteen, they can choose a character for fusion. Once the fusion is successful, they will gain the special abilities and growth attributes of this character! Then become stronger step by step, gain extraordinary power, resist all races, and kill monsters! Li Xuanfeng, who awakened the memory of his previous life on Earth, discovered that the characters that people fused were all from the three anime One Piece, One Punch Man and Dragon Ball! Due to the huge information gap, Devil Fruit users have become people's most enthusiastic fusion targets, while Saitama and Sun Wukong, the two biggest ceilings, have been ignored! Li Xuanfeng, who originally only wanted to fuse Saitama, actually successfully fused Sun Wukong at the same time. Thus, an ultimate potential stock with Saitama's physique and Saiyan's physique was born! When all those who were optimistic about Li Xuanfeng expressed disappointment in him, Li Xuanfeng grew silently. Until endless monsters came and wreaked havoc on the world, and all the strong men were helpless, Li Xuanfeng stood up and smashed the world with one punch, turning the tide. The whole world is completely boiling at this moment! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
