I Am so Invincible That I Want to Upgrade Again

"Old man, what is this? Are you kidding me? I want sex, so why don't you give me this?" Ye Hong said. "This is a good thing. The outside world depends on this." The great sage rolled his eyes and said, "What? Don't you want it? Just give it back to me if you don't want it!" ???? Ye Hong was about to beat up the old man in front of him, but he knew that if he did it accidentally, he would kill the great sage. Ye Hong didn't know how powerful the great sage was. He only knew that he would kill him even if he controlled the strength of his attack. ????"Okay, I won't argue with you anymore. You also know that your current strength is too strong, and this is the only way to do this." The great sage shook his head helplessly: "Don't worry, as long as you upgrade in the outside world to be strong enough not to destroy the town, you can come back then." The already invincible protagonist actually has to go to a lower realm to upgrade again....!!! This novel and its characters are purely fictitious.
