[No system][Weak cheat code][With space][Not a saint]

As a freshman, Chang Ming is attending his first class in college.

The world was told to enter the world of train survival.

Each stop here is an independent little world, full of wonders.

Various rules have also been set on the train.

Flight attendants are strange beings. No one can disobey the rules they set, and everyone is afraid of coming into contact with them.
