Burning Spring Lake, located on the edge of the Secret Realm, is a place where immortal blood gathers and covers a vast area. Logically, Ning Yujing would not be able to find him in a short period of time.
However, Han Ye had a feeling that she had a way to locate him.
Keep in mind that he had only just arrived at the dragon's lair at the bottom of the lake, and Ning Yujing was close at his heels.
This incredible speed led him to suspect that she must have some means of tracking him.
He collected his thoughts and turned to Chu Xianyu, who was beside him, and asked,
"As the leader of this expedition to the Secret Realm, shouldn't Ziwei Sky have taken some remedial measures? Or is it that she hasn't realized the Secret Realm has been invaded by the Demonic Cult?"
Chu Xianyu replied, "The inside of the Secret Realm is completely isolated from the outside, I'm afraid that might be the case."
