He did not dare use Synchronous Playback.
After all, he was being carried on a shoulder. Once he tries to use his energy, he might be detected by someone with a unique ability which would get him into trouble. He is here to investigate for clues, not deliver himself to death's door.
Su Hao lost track of time while they walked and carried him.
Thud!
Su Hao was thrown onto a bed, then these men left. A few moments later, a loud sound echoed.
Boom!
That was the sound of a metal gate closing.
They left?
Su Hao began to make a move.
Swish!
As Synchronous Playback was activated, the surrounding scene appeared in his view once more. After ensuring those men had left, Su Hao opened his eyes. However, even when he was psychologically prepared, Su Hao was still shocked by what he saw.
It was a huge, spacious room.
