After Su Haimei and Ying Feiqiong left the huge black tower, the air zone near the huge black tower recovered its tranquility. Nobody could be seen within 600 miles like before.
However, nobody could imagine that the 100-m high portal of the huge black tower suddenly opened after the two women left there for less than 2 hours, light flowing over its smooth and seamless surface.
It was full of terrifying black fog inside the tower, which gradually formed a very deep black tunnel at the entrance like a swirl in the water.
At this moment, if any human immortal generals or demon generals saw it, they must widely open their mouths out of shock.
The tunnel was covered with swirling black fog on both sides. It was also pitch-dark at the end of the tunnel, which seemed to be leading to a mysterious time and space, which contained a terrifying, great power.
