There were a few system novels related to demon hunters that he could recommend. The first one was "Demon Hunter System (Sad Dante)". The story was about the protagonist Su Hao becoming a contractor of a nightmare realm and entering various nightmare realms to carry out missions. In addition,"Reborn Demon Hunter (Decadent Dragon)" was also a system novel. The main character, Ye Qi, became a demon hunter after transmigrating and climbed to the top through the game system.

As they communicate more, their relationship changes from one of enmity to something more ambiguous and potentially positive.
