The Strongest Big Brother System

Bai Yuechen died during his tribulation and received the Older Brother System. To restore his cultivation, he must become the protagonist's older brother in various parallel worlds and help the protagonist fulfill regrets left unresolved. Bai Yuechen, who favors simple and forceful solutions, takes the most direct approach. Fox Spirit Matchmaker world “You want humans and demons to coexist peacefully someday? No problem. I'll make you their one and only king. Anyone who refuses to obey gets a beating.” Naruto world “You mean you want to put an end to all the wars in this world forever? No problem. Have you heard of a man named Ying Zheng? Unification is the best way to end war for good. I'll teach you the right way to have the Qin king sweep across the six realms.” Bai Yuechen's motto is: If something seems a little hard to do, just get the whole world to do it with you. That makes it much easier. The worlds currently planned are Hokage and Fox Spirit Matchmaker. Zhuxian and Sword of the Immortal IV may be added later.
