All Lin Xun had to do was wait—wait for the Evil God to traverse the Void and leave this world.
He did not know exactly how long he needed to wait, but the Underworld Game had hinted that the plot of this chapter had completely changed due to the Firefly World.
Therefore, the event of the Evil God crossing the Void must inevitably occur before the end of this chapter.
Even more so, when the Evil God crossed the Void, it could very likely be the moment when the end-event was triggered!
In Lin Xun's estimation, there were possibly two moments when the Evil God would leave this chapter.
The first was after the end of the battle in the Mysterious Sea, when the plot involving Vermilion and Penglai Immortal Island had concluded.
No matter whether the Evil God sensed that the Proxy Emperor Wu had died, it would leave this world due to its preparations and head towards the Firefly World.
