He Zhanyin immediately bounced up from the bed.
However, he didn't make any sound.
He casually picked up a jacket and draped it over himself.
At some point, a gun had appeared in his hand.
Looking towards the door, he was in a state of high alert, silently walking over.
He didn't lean against the door, nor did he use the peephole to see what was happening outside.
Instead, he leaned against the solid wall, placing his ear gently against it.
After a while, he frowned.
Why is there no one outside?
What was that loud noise just now?
At this moment, he cautiously walked to the door, looked through the peephole into the corridor, and indeed found no one.
But he still didn't open the door immediately.
Instead, he found a small mirror in the room.
Slightly opening the door, he used the mirror to check the corridor.
Seeing there was indeed no one, and no sign of anything strange.
Only then did he relax.
Still, he was quite puzzled.
What had just happened?
