When the Doomsday Comes, I Become Stronger by Playing Games

When the apocalypse came, the zombie virus broke out.

Time traveler Leon was surrounded by zombies when he was looking for food.

When Leon thought he would face certain death, the game system was activated.

"Playing the game of smashing the mouse will increase your strength. Congratulations on getting the gene strengthening pill!"

"Kicking football game to increase your speed. Congratulations on obtaining the legendary agility skill!"

Leon continued to unlock new games by killing zombies.

Leon began to look for the zombie while others were still hiding from the zombie in the apocalypse.

"What? I'm going to kill all the zombies in the apocalypse?"
