Found

The demon hunters seemed to have disappeared.

Rushing over to their workplace, Hao Ren did not find Liu Sheng and Zhao Xi. However, it was almost a certainty that the mass disappearance of the demon hunters was true. He brought Rollie home and kept mumbling to himself on the way, "Half a month ago, the demon hunters showed no signs of abnormality. Going further back, they had even gone to the secret realm in South America with Hasse. All of this happened not too long ago. What could have happened to the demon hunters now?"

Why did a powerful race which ended the Mythological Era, and a group of supernatural beings with no natural enemies on Earth disappear in such a short period? What made them go?

"We were occupied with the fleet of arks earlier and completely overlooked the demon hunters," Hao Ren said, pouting as he was talking to the MDT telepathically. "Now they're gone. There aren't many clues that we can work on now," he said.
