Ink Steel

"Zuo Yue must have escaped from here! It'll be difficult to return here if I chase after him." Duan Ling Tian looked at the entrance of the stone staircase before him that was shrouded in a faint light shield. The expression on his face was terrifying.

The light shield before him was created by a unique Inscription Formation.

It did not matter who it was, it would remember one's aura as long as one crossed over it. As a result, one would not be able to cross over again in reverse direction.

Due to the fact that this Inscription Formation was created by a Martial Monarch powerhouse, only a Martial Monarch powerhouse would be able to forcibly remove it.

Otherwise, one would have to abide by its rules.

If Duan Ling Tian crossed over the light shield created by the Inscription Formation now and entered the entrance of the stone staircase, it was uncertain if he could catch up to Zuo Yue.
