"I need to call back the Holy Son of the Yin-Yang Sect, or else he'll be seen through just like before."

Gu Tianxing temporarily devised a preliminary plan. He considered whether to directly ask the Old Ancestors to take action, even if it meant destroying part of the Dao Prefecture.

But he realized it wouldn't be that easy. This person was not like the initial Xiao Han or Fang Yong; his strength was already quite high, possessing at least a Holy Stage weapon.

If it turned out to be a System template, and Zhang Xuan teleported away after the Old Ancestors arrived, there would be nothing they could do. Moreover, he could see all weaknesses, indicating he wouldn't be constrained by any Slave Seal.
