[Comprehensive + Jian Wang 3] This Pet-Raising System Seems Off

As a homebody, and a homebody who’s hopelessly addicted to Jian Wang 3, Fang Shen says he can accept transmigrating, more or less. A Jian Wang 3 System comes with him? That should improve his chances of survival. He’ll never admit he’s a little excited. There are main quests? Let’s see how they go. ...Hey, wait. Why does this System get so weird after upgrading? Is it really okay to raise it like this? Or, more to the point, can this thing even be raised?! ↑ As described above, this is a mindless crossover story about a homebody carrying a Jian Wang 3 System as he travels through anime worlds. First stop: Fate. Second stop: Bleach. I haven’t decided where he’ll go after that. Please jump into this story fully prepared to get your head bashed in. I, the author, have already evolved from a diligent updater into Togashi, and on top of that, I’ve evolved into an evil stepmother. In short, I’ll do my best not to abandon this story... This story has no outline. I just write whatever comes to mind. Too late. It’s already been abandoned.
