Wei Cheng set off alone,
He didn't bring anyone with him.
Shortly after he left, there was an extraordinarily faint flash of blood light on Qi Mei, invisible to the naked eye. Clearly, the Blood-eyed Demon Monarch was accelerating his monitoring speed.
Not just Qi Mei's.
Others, such as Qin Yang, the Qi family, Duan Jianghai, Yu Liang, etc. Every capable cultivator of Earth in Cangwu City, one by one, had a faint flash of blood light every few minutes.
This blood light was even undetectable by the person themselves, and it wouldn't affect normal cultivation, or battle, but it could pinpoint the exact location of those who have been marked.
Meanwhile, on Earth, in the Underground City, there were also faint blood lights flashing on Liu Sui, Zhou Wu, Yang Li, and the others.
Even within the trial areas in the other worlds, faint blood lights blinked occasionally on the bodies of many powerful trialists.
Almost no one could avoid it.
