I am chosen by the Four Gods, and you ask me to save the world?

A countdown to the end of the world hangs in the sky, and four malevolent gods appear in his dreams, inviting trouble. By day, he's immersed in science; by night, he enters his dreams to offer "physical prayers" to the four gods. Then, the reborn, beautiful, and wealthy schoolgirl arrives, handing him five thousand yuan as a "friendship fee": "The end of the world is coming!" He falls into deep thought. Saving the world? Well, that reminds me. Begin the prayer!
