Advance?
The Imperial Void Celestial King and the others had already entered, yet the group still couldn't sense any commotion at all. According to what He Runhai had said, they should have encountered grave dangers if they entered. Even the Imperial Void Celestial King wouldn't be exempt from this.
After all, this was the handiwork of a Pseudo-Heavenly Venerate. Even though he was already dead, his handiwork still remained heaven-defying.
That being the case, entering would equate to seeking death.
Perhaps they should retreat?
But was there still anywhere for them to retreat?
He Runhai had clearly prepared a trap. He had taken advantage of everyone to shatter the large formation, and it was now time for him to reap the rewards. Would he allow Ling Han and the others to leave?
It was only logical to assume that he had made other preparations to prevent them from leaving.
