The Maxed-Level Succubus Picks up the Lost Sword Maiden at the Beginning.

It is said that in the fantasy world, the jungle will prevail, but why do the strong men I meet rush to give me magic weapons? It wasn't until I picked up the heroine who lost her power that I understood the passive skills of my fully-leveled succubus. I wanted to keep a low profile, but all the big guys surrendered one after another. Even the cold swordsman blushed and wanted to become a Taoist companion with me. What's even more troublesome is that the gentle saint I rescued looks at me more and more wrong... And all of this seems to be related to the war between gods and demons ten thousand years ago?
