Global Travel: Start with a Fully Leveled BOSS

The era of global alien travel has arrived, and countless people have poured into this world of swords and magic with systems, missions and ambitions, eager to become the protagonist and write legends. However, no one knew that as early as ten years before their arrival, there was a player named 'Lin Ye' who had already cleared all the dungeons, conquered all the forbidden areas, harvested all the artifacts, and became the only and supreme being in the world - a full-level existence. While the cute new time travelers were still scrambling for a slime, Lin Ye was using the artifact 'Twilight of the Gods' to skewer magic dragon meat and barbecue it. While the brave men were still rushing around for job transfer tasks, Lin Ye was being cried out and begged by his former ultimate bosses to become his younger brother. While princesses and saints from various countries were still favoring the geniuses who traveled through time, the myths in their minds were being summoned by Lin Ye to serve tea and water. Lin Ye wanted to retire quietly, but the time-travelers were too troublesome and always wanted to make big news. "What? You said the revival of the Demon King of the North is a world-destroying crisis?" Lin Ye scratched his head: "Oh, that boy, you didn't rub my back well last time. I punished you by cleaning the toilet. Why did you run out?" This is a relaxed, everyday (pretentious) story about a max-level boss watching (and occasionally saving) a group of cute new time-travelers working hard to "upgrade" in a novice village.
