The End Is Coming! I Rely on the System to Survive in a Convenience Store

Zhang Yun was originally just an ordinary girl working in a convenience store. She just wanted to work in a convenience store and make money. But I didn't expect that frequent nightmares would always invade Zhang Yun's dreams. I didn't expect that the dream was actually a doomsday dream? And it happened ahead of time in reality. Fortunately, the system at this time had already decided to bind Zhang Yun without authorization, allowing Zhang Yun to survive in a convenience store. The system will protect Zhang Yun from surviving in the apocalypse.
