The pupils of the Diamond Sect's ancestor contracted slightly and goosebumps rose in his heart. His footsteps instantly slowed down as he cautiously left this area step by step. Only then did he heave a sigh of relief and speed up again.
However, he didn't pursue or get too close. He had already realized how strange this youth was. At the same time, he knew that the other party had a method to cause the anomalous substances to instantly thicken. Hence, he didn't plan to get too close and forcefully attack. Instead, he planned to rely on his cultivation base to keep an eye on the other party and wait for daybreak before attacking.
Although he was a Foundation Building cultivator and had to be so careful when dealing with a Qi Condensation cultivator, this matter would damage his reputation as a Foundation Building cultivator. However, under such circumstances, the Sect's ancestor still decided to prioritize safety first.
