With the Almighty Doomsday System, I Am Invincible

Ning Shen, a security guard, earns 5,000 yuan a month and is called a "watchdog" by his colleagues. He saved the life of a beautiful CEO in exchange for a check of 100,000 and a "thank you". And then he died—in a hospital bed. When he woke up, the world was a wasteland with zombies gnawing around him. The almighty apocalyptic system is bound and the double door is opened. Lack of supplies in the last days? Go back to Hyundai and buy it. Is there an enemy in modern times? Come back with super powers from the end of the world and crush them. Do zombies need crystal core upgrades? Sorry, I upgraded directly using the system. Later, he proclaimed himself emperor in the last days and became the supreme ancient martial artist in modern times. Someone said: "Does a security guard deserve it?" Ning Chen smiled: "A security guard becomes the co-owner of two realms... It makes sense, right?" This novel and its characters are purely fictitious.
