Chapter 2981-discovered a business opportunity

"There's a formation?"

Tang Hao was surprised.

"Of course. These are all formations set up by celestial Immortals, so they're extremely sturdy. Also, the only thing that can control the formation is this formation disk. Now that you've taken it, you're the only one who can control the formation from now on."

The old man laughed.

"If you're still worried, you can set up some arrays yourself!" He said.

"Alright!"

Tang Hao nodded. He took the formation plate and refined it easily.

He carefully examined it and confirmed that there was nothing wrong with it.

With his array Dao attainments, even the sky immortal experts here would not be able to compete with him. He would know if there was any tampering with it with a single look.

Fellow Daoist, if you have any needs or trouble in the future, you can find me over there. That is the Shang Qing mountain range, the center of our Grotto-heaven is there."
