The Second Time Traveling, Has the World Become a Game?

"Everyone here, whether you are a human, an elf or an orc, a magician, a bard or a paladin, there is only one reason for us to gather here!" "Destroy the dog mastermind who claims to be a god!" —————————— After traveling from the earth to the Tifa Continent, Zi Ran squatted in the mage tower and conducted hundreds of years of magic research, becoming a god. Before the god's seat was even warmed up, the terrifying magic energy bomb called "Purifier" blew up the Tifa Continent and the hundreds of billions of creatures on it until nothing was left - so he traveled through time again. This is the continent that was completely gamified three thousand years later, planned by the dog who claimed to be a god. The original all-powerful mage was split into countless professions, and the channels of magic were monopolized by gods. As predicted by God, the players on Earth arrived as scheduled and became a major factor in the situation on the continent. This last original mage from 3,000 years ago, the strongest level 1 in the mainland, and a man without magic, will become the all-round mentor legendary among players. He will use the power of (exploitation) players to rebuild the magic industry system, mass-produce magic scrolls, kill the false gods who have stolen the god's throne, and lead all civilizations on the continent to escape from the fatalism that they will be destroyed by magic bombs.
