World-Shattering Calamity

The male protagonist Li Ban entered the book because of a comic book. Because Pangu was not dead in the book, humans could not appear. Then the slow-flower world came into reality. After Pangu appeared in the real world, time and space began to reverse, and he returned to the ancient times when the world was created. People in the real world no longer existed. Only Li Ban survived after being infected with the ancient evil spirit and became a demon. He could only save the world and restore human civilization in the real world by killing the Pangu demon spirit.
