100 Ways to Use a Tentacle Monster

In a dangerous world where humans and monsters coexist, Qin Xin finds a tentacle monster.

With the principle that "a free find shouldn't go to waste," she trains it, ahem, and develops a hundred different uses for it.

Until her "tool" independently figures out some strange uses of its own, like ooxx.

Qin Xin has to admit, things are starting to get out of hand.

1. When you feel cold, let me curl up around you in neat rows. I'll keep you warm.

2. When you feel hungry, cut off one of my tentacles. I'll try hard to taste good.

3. When you're in danger, you can throw me out. But don't forget to pick me back up. I'll become even more useful.

100. When you feel lonely, I'll keep you company. (Whether you want me to or not.)

P.S. The main text is in third person, with post-apocalyptic elements. A heroine who has no feelings and just wants to survive x a pretty (?) male lead who's been developed in all sorts of ways and is desperate to cling to her.
