Sun Hang took a deep breath, closed his eyes, and stepped forward.
He silently told himself in his heart that the airtight door didn't exist, and there was nothing on the path ahead...
After seven or eight steps, he opened his eyes and found himself in another corridor. Turning around, he saw that the airtight door behind him was still tightly shut.
"Hey... this ability is really handy, just don't know if it's a one-time thing."
Sun Hang looked around; this corridor was much wider than the escape passage from before, and doors began to appear on both sides of the passage.
Although most of these doors were locked, for Sun Hang in his current state, doors were merely part of the scenery, without any practical significance.
He didn't even bother to use the door and went directly through the wall into the first room on the right.
This should be a bathroom, with a row of dirty ceramic urinals on one side of the wall and three stalls on the other side.
