Three months later, Ye Mo has set the new sealing formation method. He made piles of formation flags. Mountains of materials were turned into formation flags.
A year later, Ye Mo looked at the pile of formation flags and rejoiced that he encountered the Du Ting god sect leader. Otherwise, with the materials he prepared it wouldn't even be enough to forge even half of the formation flags.
Li XIu was helping Ye Mo on the side too, organizing the formation flag types. The two didn't say much but they were getting more and more worried. They thought that the formation would last decades but they could visibly see the formation flags deteriorating.
With this speed, the formation could completely break in three to five years and the the tunnel between immortal realm to the Divine Dao Realm would completely open.
