Ye Yunfei said gratefully.

"Senior, that ghost formation master outside has a better formation level than me.

He is currently studying these three formations outside, and I am worried that sooner or later he will find a way to break the formations."

Ye Yunfei said a little worriedly.

"Then you should have a good battle with him.

If he studies it, you can study it too."

The powerful demon said.

"Although I am not very good at formations, I have collected a lot of formation secrets back then. Now I will give you all the formation secrets I have collected.

You can use it as a reference."

The powerful demon said with a smile, then waved his hand, took out a dozen jade slips of martial arts, and sent them to Ye Yunfei.

"I got all these formation secrets from some of the more famous formation masters of my time.

Many of the formation masters are not from your time and space.

These formation secrets should be of some help to you."
