The Strongest Substitute in All the Worlds

I once galloped on the sea, saved Ace, and fought against three generals and four emperors. I also traveled to Zhuxian, saved Baguio, and fought against the Zhuxian Sword Formation. Eriyi's future will be rewritten by me, and Kikyo's future should be even better! If you have to ask what the strongest generation plans, one sentence! I'll beat those you can't beat! I will save those who you cannot save! All heavens and worlds! I! It's the strongest substitute! This novel and its characters are purely fictitious.
