The Chronicles of Heaven

The floods have receded and the weather has become chaotic. The last person who knows how to gaze at the stars will use a standard watch and half a scroll of broken books to re-determine the vernal and autumnal equinoxes for the human beings in the ruins. Detailed introduction: The 8,000-meter-deep flood crossed the Himalayas and erased all the marks of the old era - the clocks stopped, the calendar became invalid, the sun, moon and stars still moved, but no one could understand the seasons in their mouths. Among the survivors was a young man named Lin. Before the catastrophe, he was a member of the ancient culture and the last person to follow the reclusive Taoist Rong Gai to learn "Kaiyuan Zhan Jing" and "Yi Jing". While people were rummaging through the mud for cans, Lin climbed alone to the shelter's highest rock wall. He started stargazing. It is not the observation of precision instruments in observatories in the old days, but a standard watch made of a bamboo pole and a pile of mud to measure the length of the sun's shadow; it is to identify the position of the twenty-eight constellations and deduce the point of the Beidou every clear night. He told the tribe: It's not that the sun is getting hotter, it's that you planted your seeds at the wrong time. So he re-enacted the law from scratch: ——The beginning of spring, Yang Qi begins to rise and breaks through the earth; ——Shocking of Insects, thunder and insects emerge, preparing for plowing; ——Grains of awns can be harvested in the valleys with awns; ——Frost falls, and the cold air always arrives and returns to hiding. One generation teaches another. Lin taught them how to identify the stars, how to carve wooden signs, and how "the unity of heaven and man" is not a mythical word, but a concrete perception that the sun's shadow grows one inch longer and the earth's temperature rises one minute. He taught them to recite the remaining sentences from "The Thousand-Character Classic" - "Cold comes and summer comes, autumn harvests and winter hides", and then told the children that this sentence contains everything they need to survive.
