The Blood Prison Great Saint and Sin have been gone for a millennium, traveling in the Human World. Time passes slowly, but for the disciples in the dojo, it seems like they were only gone for a day.
During his travels in the Human World, Sin broadened his understanding. He encountered all sorts of things, saved lives, was deceived, and even killed people. He also had conflicts with major sects.
However, all grudges disappeared when he returned to the Daoist Field of the Beginningless, because no one could forcefully charge against Sin.
These experiences made him grow a lot, and he began to contemplate what kind of person he wanted to become.
The Blood Prison Great Saint followed Sin, saying he wouldn't interfere, but when faced with the siege of major sects, he couldn't stand by and took action. This also eased his relationship with Sin.
Those two quieted down, but among the third generation disciples, a fearless one emerged. Gu An didn't feel annoyed but found it interesting.
