Express Deliveries by Airdrop in the Apocalypse

When a scarlet blood moon tears through the sky and waves of corpses swallow civilization like a tsunami, Su Ran wakes up in a filthy sewer. But what rings in his ears isn't the snarling of zombies. It's a cold, enticing synthesized voice:

“Ding! Apocalypse Express System bound successfully. You have one undelivered package. Please open it promptly. Survival countdown: 23:59:59.”

Staring at the package that has appeared out of nowhere, stamped with a bizarre smiling-face logo, Su Ran is utterly bewildered. Inside the first package is a rusty Tang saber sharp enough to cut through steel.

The second holds mysterious jerky that can strengthen his body.

The third contains... a miniature nuclear bomb capable of obliterating everything within a ten-meter radius?!

Open! Open! Open!

While everyone else struggles to survive the apocalypse, risking their lives for a moldy piece of bread, Su Ran is busy opening packages. Awakened crystal cores? Right there in the box! Prehistoric technology? Delivered to his door! Mythical creature hatchlings? Signed for successfully!

System missions? Kill! Enemies in his way? Kill! Anyone coveting his packages? Kill! Armed with the divine weapons he unboxes, Su Ran becomes a roaming package-opening fiend, carving a bloody path through mountains of corpses. His goal is simple: survive, open every package, and find out what earth-shattering secret lies behind this damn System! No heroine! No saintly do-gooder! Just an endless stream of packages and a ruthless unboxing spree! Ready to witness a deliveryman unbox the entire universe in the apocalypse?
