Chapter 1193: Zhou Shu's Achilles' Heel (1)

In an unknown grotto-heaven, there were seven or eight Grotto-Heaven Masters and countless unknown Grotto-Heaven realm experts.

There were a total of 36 famous grotto-heavens in the world, but it didn't mean that there were only 36 grotto-heavens.

For Grotto-Heaven realm experts, when their cultivation reached a certain realm, they could open a grotto-heaven. But only when they reached the Grotto-Heaven Master realm could their grotto-heaven have a complete ecology.

This was why Grotto-Heaven Masters were so much stronger than ordinary Grotto-Heaven realm experts.

No matter what, there were always some hidden experts whose true strength was unknown to outsiders.

Now, this unknown grotto-heaven was the grotto-heaven of a mysterious Grotto-Heaven Master.

To Grotto-Heaven Masters, grotto-heavens were undoubtedly the most secret place.

These people were gathered here, and their gazes all landed on a figure covered in a black robe.
