Nian Shutong channeled the power within her body, a golden light flashed by, enveloping the entire key, and sent it into the lock. Nian Shutong didn't know how many times she had turned this key, but not once was it successful.
She didn't understand why, but during the last strike of her Heavenly Tribulation, she saw information about this lock and key.
She couldn't quite grasp what connection this lock and key had with the Cultivation World where she once existed.
But Nian Shutong had only one thought, regardless of past affairs, she was just her current self.
With a "click" sound, the key turned, and the lock opened.
Centering on the lock, a transparent door appeared in front of Nian Shutong.
According to records, this was a door to a secret realm, but what lay inside was something she didn't know then, but would soon find out.
Nian Shutong stood up with the lock and key, faced the door in front of her, and pushed it open.
