When the Apocalypse Comes: Get the Ability to Upgrade from Dropped Items

One day, with the global power outage, some mysterious portals suddenly appeared around the world. These mysterious portals became passages for monsters that only existed in fantasy worlds.

However, one day later, many powerful monsters suddenly disappeared. Under the leadership of the brave, people discovered the crystal that existed in the monster's body, the magic crystal. As long as you eat it, you can activate the system and become an "awakened one." People all realized that the only way to survive seemed to exist only in a fierce confrontation with unknown powerful monsters. This novel and its characters are purely fictitious.
