In fact, this was not a spatial Dharma artifact.
Instead, it was Li Hao's system world.
Li Hao's system world was an independent space. Moreover, as Li Hao's cultivation increased, the space in the system world became wider. At this moment, the space in the system world had long become wider than the underground world.
Therefore, it was not a problem to contain these Demon Kings and Great Demons. This was also the best way.
With a wave of Li Hao's hand, more and more Demon Kings and demons were sent into the system.
In just another moment, there was no longer a single greater demon or Demon King-level demon beast left in the entire Underworld.
After doing all this, Li Hao looked up at the teleportation array again.
Li Hao felt some changes in the world because of his cultivation and froze again.
He had no choice but to leave!
