Prehistoric: the Man Crawling Out of the Demon Ancestor's Gun

Shen Yuan, a 28-year-old social worker, worked overtime for three months in exchange for a trip to Mount Taishan as a reward from the company. Before reaching the top, I stumbled off the cliff by a crooked-neck pine tree. When he opened his eyes again, he found that he had turned into a gun. The soul-eating spear is an innate treasure and the natal killing weapon of Demon Ancestor Rahu. At this moment, Luo Hu is holding it, harvesting the remaining souls on the battlefield of the Dragon and Phoenix Tribulation. One shot saves a life, and the shot never misses. Shen Yuan was trapped in the gun and was repeatedly crushed by Luo Hu's murderous intent, and his soul almost fell apart. There is only one reason why he can survive: when he fell off the cliff, his soul passed through the long river of time, and there were fragments of the avenue of time embedded in his soul. On the night of the decisive battle between the dragon and phoenix tribes, Luo Hu's gun missed by less than a centimeter. Shen Yuan seized this opportunity, detonated the time fragment, broke away from the gun, and ran north without looking back. Behind him are the ruins of the Dragon and Phoenix First Tribulation, and in front of him is an unknown wasteland. In his previous life, he had read more than two hundred ancient novels, and he knew that Hongjun was about to attain enlightenment in Mount Buzhou, that Nuwa could create humans, and that witches and demons would fight each other. He knew every key node in advance. There was only one thing he had to do: stand in the right position and get the right merit in every earth-shattering event before being found by Rahu. From being the target of the Demon Ancestor's pursuit, he has become a being that even the Demon Ancestor must be afraid of. Then jump out of the chessboard and become a saint.
