Apocalypse: From the Start, I Had a Mythical Treasure Chest, and I Slaughtered My Way Through the Zombie Horde

[Apocalypse + monster-slaying and leveling up + game + power trip + epic clashes] Gu Fan was reborn before the apocalypse game descended. In his previous life, his girlfriend betrayed him. He fought off the zombie horde, only to be killed by humans from his own faction. This time, he killed his two-faced girlfriend first and madly seized the opportunities that had belonged to others in his previous life. Then he bonded with the Treasure Chest Evolution System and got a Mythic-grade treasure chest from the start! From then on, Gu Fan carved his way through the entire apocalypse with a blade in hand! Time passed. After killing countless zombies and reaching the end of the apocalypse, Gu Fan finally discovered the truth behind it all... [Some elements will be interspersed among the traditional apocalypse leveling-up sections. They won't take up much space, and monster-slaying and leveling will resume afterward. If you can't accept that, don't read.]
