However, as Hao Chen controlled the sphere of light and continued to fly far backward for a considerable distance, he still hadn't encountered the hall entrance they had come through, nor had he come across any walls—it was as if there was only a void behind him. However, Hao Chen was certain that after the four of them had entered through the hall doors, they hadn't walked this far, not more than fifteen or sixteen meters at most. Soon after, the four realized something was wrong and just as they thought of turning back, they found the doors had already closed.
"Hao Chen, did you notice it too? The fireball I controlled has already flown out nearly a hundred meters, but still hasn't touched the edge of this palace. Bu Yun, Jing Potian, you two control your spheres of light to move upwards and to the left, let's see if we can find the edge of this palace." After speaking, Yao Wumeng held his breath and concentrated, his eyes fixed on the fireball that had shrunk to a tiny red dot.
