Surviving the Apocalypse: A God-Tier Sign-In System from the Start

【Apocalypse + infinite pocket dimension + rebirth + revenge + ruthless and decisive + System + no female lead】 Death fog + acid rain + zombies + mutated creatures + alien races + the uncanny + jiangshi... The apocalypse arrives, and disasters follow one after another. Humanity perishes in one catastrophe after another, and the population plummets by 97%. Nearly everyone left gains superpowers. In his previous life, Ye Chen kindly took in his girlfriend and brother, only to be betrayed and killed by them. But he unexpectedly returns to the time before the apocalypse, awakens a sign-in System, and starts with a god-tier safehouse, an infinite pocket dimension, and innate superhuman strength... Short on supplies? He can sign in for a hundred million worth of goods, ten tons of Wagyu beef, and a hundred tons of Lafite. While everyone else is fleeing in panic, Ye Chen is living even better than before. Girlfriend: I was wrong! Please, give me something to eat. Fake brother: You're my dad! I was wrong. Please, just give me a quick death. Auntie Zhang: You orphan! Hurry up and let me and my grandson into your house to shelter! Other jealous neighbors: We don't even have food. Why does he get to live so well? Get him! Take his food and share it with us. Ye Chen: Heh. My pets eat better than all of you. Jealous? Good, that's the right reaction.
