There's no other way. Since the path back has already been blocked, he can only navigate forward in the maze.
It seems to be due to the presence of the fleeing furry mutant creature, the number of mutant creatures he encountered in the maze far exceeded his expectations, and each one attacked him recklessly, even if injured, they wouldn't flee!
In this situation, he couldn't follow the injured escaping mutant creatures like last time in the underground city maze to find the exit of the maze.
Because the passage was narrow, weapons were less effective, and the mutant creatures were attacking recklessly, he was even injured several times.
He spent a long time navigating the maze before finally squeezing out, at the exit, he was still in the middle part of a massive stone column peak.
