Chapter 537 Mysterious Woman

"Buzz!"

Xu Ping'an felt a pulling force emanating from his Niwan Palace.

This force was not from anything else, but from the Supreme Immortal Seal given to him by Tang Xinyue.

"Could it be that there is an Immortal Emperor Seal or an Immortal Emperor Seal within this bamboo forest?" Xu Ping'an muttered to himself.

If it were one of these two things, they would indeed be of great use to him.

His soul realm had already reached the level of Seventh Rank Peak, and if he were to merge in an Immortal Emperor Seal or an Immortal Emperor Seal, he could consolidate the three cities downstream of the Tianlong River as well as the entire Beichen Sword Sect.

At that time, his soul power would also become much stronger.

Thinking of this, Xu Ping'an couldn't help but walk towards the bamboo forest.

Soon, Xu Ping'an arrived at the edge of the bamboo forest.

"Eh, it's actually a Tenth Rank Tiangang Wind God Killing Formation." Xu Ping'an was somewhat surprised.
