According to Zhou's Gua Master's Biography, Six Coins Gather to Destroy Immortality

"If you cannot calculate all the hexagrams, you are afraid of the impermanence of heaven. If you cannot gather all the lines, you are afraid of losing your mind and soul." Zhou Yiming's grandfather, Zhou Mingxuan, started a hexagram to save his wife, and met the three-eyed hexagram master. From a "follower" to an "independent hexagram master," he finally left this "Supplementary Notes" and passed away suddenly. It was not until his grandson Zhou Yiming received a rusty "Jiaqing Tongbao" in Panjiayuan that he started to search for the hexagram. The hexagram showed that the key clues were somewhere in the Tianshan Mountains of Xinjiang. Su Xuanyi appeared with three other Yao coins, indicating that she was looking for "descendants of the Zhou family" in the mainland, and combined six coins to solve the "Thousand-Year Hexagram Tribulation". As the millennium hexagram tribulation gradually emerges, the hexagram images come back, the line changes devour the soul, the test of human nature, the ethereal hexagram images, everything is here.
