A college student and three roommates were studying formations in an abandoned and unfinished building late at night. The building caught fire. For some reason, they couldn't escape. The formation on the soles of their feet was activated, and four people traveled through it one after another.
This college student happened to be a disciple of the Demon Sect. He wanted to die, but luckily there was a system, but this system seemed to be useless and useless.
