Magic ring

As an ordinary person, Jake suddenly acquired a magical ring one day, which allowed him to travel to a game world. In this game world, he was not the only "player," and he could bring skills, techniques, divine pets, and even people from there into reality. You think heavenly-grade techniques are impressive? I can sell them by the pound here. You think an expert at the Transformation Realm is unrivaled? Sorry, in my presence, they can only be subordinates. You say there is no cure for this illness? Come, taste the elixir I concocted. I guarantee it will cure your ailment and bring you back to full vigor. With the ring in his possession, Jake manipulated various realms in reality, unified nations in the game world, and conquered the demonic realm.
