Li Wei crushed the Communication Crystal.
This was to prevent the Tower Master of the Elemental Tower from hearing what came next.
When the Communication Crystal on the Elemental Tower Master's end lost contact, he didn't think anything was amiss.
He simply assumed Li Wei was fleeing for his life and had no time to talk.
Li Wei looked at the Legendary Witch Lich and said, "You heard him. This place is probably about to be utterly destroyed."
The Legendary Witch Lich nodded. "Yes, I know."
"I'll be waiting for your news, then."
Li Wei nodded. "Alright."
The Legendary Witch Lich cast a Teleportation Spell and departed.
Li Wei opened a Space Teleportation Gate as well. He glanced back at the boundless Undead Army that stretched as far as the eye could see.
He shook his head, stepped through the gate, and vanished.
Everything here was about to be annihilated.
Li Wei reappeared far from the Death Sky Curtain, watching from a distance while suspended in mid-air.
