Captor

The protagonist Lin Cang accidentally traveled to a fantasy world and became a person who specializes in capturing and imprisoning those people or monsters who harm the world. They are collectively referred to as 'Captors' Their abilities vary, so the Captors rank their hazard levels from small to large; D-level, C-level, B-level, A-level, S-level, SS-level, SSS-level, SSSR-level. The same goes for captor levels. The captor can improve his level by completing tasks; capture or containment. After completing D-level tasks 10,000 times, he can become C-level, completing C-level 1,000 times can become B-level, completing B-level 100 times can become A-level, completing A-level 50 times can become S-level, completing S-level 30 times can become SS-level, completing SS-level 20 times can become SSS-level, and completing SSS-level 10 times can become SSSR-level. Of course, if you have the strength, you can leapfrog the challenge and level up as long as you succeed. This novel and its characters are purely fictitious.
