The Classic of Mountains and Seas: Cultivation of Truth and Immortality

Is it really possible to become an immortal through cultivation and ascend in the daytime? Does the cultivation system commonly used in fantasy novels really exist? If all this is fiction, then why was the story of Xie Ziziran, who ascended in the daytime and became an immortal in full view of thousands of people in the Tang Dynasty, recorded in the annals of history? This incident has been recorded in more than 80 books, both official and unofficial histories. Even the then emperor Tang Dezong personally compiled a biography of Dongji Zhenren for this purpose. Are all the ancient cultivation civilizations recorded in the Classic of Mountains and Seas real? Before starting this topic, let me answer a question first. Which one is more advanced in the understanding of the universe, the vividness of the ancient times or the modern age with advanced science and technology? Don't rush to answer, maybe the answer is not as simple as you think. We venture to guess that there may have been a developed cultivation civilization in the distant ancient times. In the distant ancient times, gods created human beings and ruled the continent. And the strange thing is that many civilizations in the world mention a special place. It is called Kunlun in the Classic of Mountains and Seas, the Garden of Eden in the Bible, and the Western Mountain in India.
