Building a teleportation array within the Yunlong Heavenly Palace, if exposed, would surely bring a lot of trouble.
But for now, this is the best way, and if it really gets discovered, Lin Chen still has his disciple Wang Tong to resolve the issue.
Thus, Lin Chen quickly found a very hidden spot in the Yellow Hall and began taking out various materials to set up the formation.
Lin Chen had always kept the teleportation array and hadn't given it to the Primordial Myriad Transformation Cauldron to refine and absorb, as it was one of his key assets and handing it over would be a waste.
One must understand, the Primordial Myriad Transformation Cauldron absorbs the energy of those materials to repair itself, only utilizing their energy, unrelated to the type of materials absorbed.
Lin Chen set about arranging the formation, which was soon completed.
He then planned to activate the formation and use the teleportation array to return to the Eastern Domain.
