Reincarnation, Reverse Calamity and Immortality

Wan Jian was originally a strong man who could look down on all sentient beings from the Nine Heavens, but during a calamity, he suddenly discovered a memory that had been erased. In order to explore the truth, he resolutely fell into the mortal world and started endless reincarnation. In this life, he woke up in a ruined temple, holding a blood-stained copper coin in his hand, which was a precious clue left by the previous reincarnation. In this world of cultivating immortals, the legends about the battle between immortals and demons told by storytellers in teahouses, the lamentations of former princesses sung by brothel oirans, and the prophecies uttered by beggars on the streets all seem to hide unknown secrets. However, Wan Jian faces many difficulties. In each reincarnation, his strength is greatly restricted, and the traditional power systems such as sects and bloodlines that are deeply rooted in the world of immortality also discipline and oppress him, seriously hindering his pursuit of the truth. What's even more troublesome is that the person in charge (the chess player) senses Wan Jian's threat and uses methods such as natural disasters to constantly suppress him. As the Nine Levels of Thunder Tribulation approaches again and again, Wan Jian not only has to break through the limitations of his strength, but also has to deal with misunderstandings and hostility caused by people around him who don't understand him. Whenever he made some progress, the chess player secretly controlled all the forces to destroy it, causing people around him to leave one after another, leaving him to suffer the bitter victory. But Wan Jian relied on the unique advantages brought by the system and continued to grow in the cycle of "receiving system instructions - completing challenges - obtaining rewards". Finally, when another catastrophe struck, he successfully saw through this chess game that spanned eternity, and realized that the so-called catastrophe was just a trick played by the chess players who were afraid of being exposed. This time, with the accumulated strength, he launched a counterattack against the chess players hiding in the clouds, letting them also have a taste of being burned by the fire of the world.
