Sword Saint Storm of Doomsday

A sophomore who loves to play Warcraft once again killed the opponent's sword master in a battle. The opponent's sword master actually dropped his machete. Out of curiosity, he picked up the machete... When he woke up, he found that he had traveled through time to a sixteen or seventeen-year-old boy, and this world was an apocalypse where zombies were rampant and human life was like grass. Let's see how he uses the skills of the Sword Master to become invincible and sweep across other worlds in this apocalyptic world. No TJ, no garbage, please feel free to collect.
