Immortals and Buddhas, Starting from Humans and Animals, Attaining Enlightenment and Immortality

[Weird cultivating immortals + grammatical folk customs + no system + single female protagonist] (Classic opening; non-routine; the rhythm takes off after ten chapters) "The white jade capital in the sky has five cities on the twelfth floor. Immortals caress my head, knotting my hair and receiving immortality. " During the reign of Yu the Great, the dynasty collapsed and all heroes rose up. Pei Qianyuan, who traveled to this world, was lucky enough to become a low-level human being. He found that not only evil spirits were rampant here, but the True Lord in the Heaven and the Immortals and Buddhas in the Heaven Beyond were even more strange and unpredictable. As the saying goes, people will always eat those who cannibalize; and humans and animals are the most sought-after things in the world and are the indispensable foundation of the Tao. Pei Qianyuan, who does not have a golden finger in the system, has only one 'talent' that he brought with him when he time traveled, a huge tumor in his brain. But it seems that this talent is not completely useless.
