Before this, whenever Jiang Liu set up a Sealing Formation, he usually used it either to block off a location or to seal a divine soul.
However, without a doubt, it had to allow Heaven and Earth Essence to freely enter and exit the Sealing Formation.
After all, for the Sealing Formation to remain active, it needed a continuous supply of Heaven and Earth Essence to support it.
But this Sealing Formation had to block the passage while also preventing that True Realm Power from entering Hongmeng Star Realm through it.
Thus, almost all the Sealing Formations he knew were ruled out and could not be used here.
Fortunately, just now, after obtaining the method for setting up that Sealing Formation, he had learned the principle behind sealing away the True Realm Power.
Therefore, after combining the Sealing Formations he knew with that Sealing Formation, Jiang Liu had managed to make one that was temporarily usable.
However, this temporary usability came with one major flaw.
The energy maintaining the Sealing Formation—the Chaos Law Power—could not last for long before being completely depleted.
It could not regenerate here and continue maintaining the Sealing Formation as the previous Chaos Law Power had.
If the Chaos Law Power had not been consumed so excessively by the battle here, that Sealing Formation would not have been damaged so easily, only to be directly and completely shattered by the Void Overlord.
Therefore, to maintain this Sealing Formation, Jiang Liu had to return here every so often and replenish its Chaos Law Power.
Although this would inevitably divert some of Jiang Liu's attention, he had no choice but to do so for the safety of all Hongmeng Star Realm.
Besides, he was currently the only one in all Hongmeng Star Realm with this ability.
