The formation patterns Hua Zizai had unleashed were none other than the Heaven-Covering Formation!
The last time Hua Yunfei had used the Heaven-Covering Formation in Reincarnation Ancient Land, the Ancestor Masters present had taken a liking to this terrifying concealment formation.
After returning, they had ordered Tianji Peak to replicate the Heaven-Covering Formation, so that it would be more convenient for those super Ancestor Masters to make a move in the future.

A group of Ancestor Masters from Tianji Peak had studied it for a very long time without success, repeatedly claiming that it was something no human could have created. It was simply too absurd.
