I Just Want to Get Off Work, but You Want Me to Save the World?

Lu Cheng was originally an ordinary young man on Earth. He accidentally opened the "beta version application" on his mobile phone and was transported to a different world called "Omega Realm". This world combines magic and technology, but it is being eroded by the "Void Plague", and all life is gradually digitizing and collapsing. Lu Cheng's mission: repair the core of the world. But the problem is - the system didn't teach him how to do it.
