I'm an Infinite Regressor, But I've Got Stories to Tell - Chapter 319

The course of commitments never did run smooth.

Intellectual Villages are old fashioned rural villages recreated with cutting edge technology. Those villages attract the Japanese monsters known as Youkai.

The high school boy Jinnai Shinobu lives in one of those villages and has a Zashiki Warashi living in his house. He tends to run across Youkai with unnerving frequency and this often leads to trouble for him.

Liu Yong has a pet snapping turtle that can grow continuously. The bigger it gets, the rivers and lakes can no longer accommodate it, so he can only go to the sea to dominate.

This is also a magical snapping turtle. Liu Yong can communicate with it without barriers, and the attributes and skills of the snapping turtle can also be shared. Therefore, someone who is the owner of the snapping turtle also criticized it.
