Apocalypse: Teyvat Gacha System

Also known as: Bored in the Apocalypse, So I Kill Monsters for Fun. Teyvat is just the name of the System. Even if you've never played the game, you'll understand right away. The old man gets a second career, then transmigrates and loses his life in a flash! Fang Mu is at home eating fries, singing, and exploring Teyvat when he suddenly transmigrates! The apocalypse?! Hey, you! Where did you dump me? I turn around and zombies are storming the building. Why does everyone else get a safe house when they transmigrate, while I get a cooking spatula? But when he sees that flash of purple before him, Fang Mu suddenly feels the spatula in his hand might actually be useful! So purple really does have a certain charm! And so a man who knows he's inside a novel, often breaks the fourth wall, and knows he's the protagonist manages to survive the apocalypse.
