[Shackles Realm]

If there was anyone in this space, the would find that Chu Wuyao was currently sitting cross legged on the ground, with an illusory lock shining brightly on her forehead and shaking violently.

Slowly, this lock seemed to be unable to withstand the impact of the invisible "hammer" and tiny cracks started appearing on its surface and spread rapidly.

These cracks started out small, but as time passed, they became bigger and bigger, occupying most of the surface of the illusory lock.

A loud cracking noise spread in the room, as if a stone or a piece of glass was about to break the next second.

Chu Wuyao didn't look at the illusory lock nor did she hear this sound however, but continued mechanically moving the Qi that she had accumulated inside her body during her cultivation journey and controlling it to attack the lock on her forehead.
