Traveling Through the Deadlock from Prehistoric Times to Modern Times

The timeline that the male protagonist was supposed to travel through was the time when Rahu was exterminated in 1997 when the zombies had a date. However, he and the female protagonist collided in the time and space tunnel and fell into the prehistoric world. In this world, Hongjun had just become a saint and was preparing to preach three times. The male protagonist and the female protagonist have experienced many major events in the prehistoric times together. In the end, can the male protagonist be able to turn the tide? Why did the Pangu tribe establish the Pangu Holy Land? Why do all the gods and Buddhas in the sky suddenly disappear? Who is the mastermind in the end? A different prehistoric world, a different zombie plane, no system, a single female protagonist, not Hongjun, not the Six Saints of Heaven. Here are the planes of the heavens, the ancestors of the four great zombies, Jiu Shu, Kuang Tianyou, Ma Xiaoling, and Otsutsuki.
