When Su Shi'an, an ancient book restorer, was sorting out a broken "Secret Record of Solar Terms", blood seeped into the pages from his fingertips, and he was unexpectedly drawn into a world of immortality based on "solar terms". There is no traditional spiritual root for cultivating immortals here. You can only cultivate by following the four seasons and using the power of the solar terms - the beginning of spring draws the energy of new buds to build the foundation, the summer solstice gathers the power of the scorching sun to condense the elixir, the frost quenches the sharp casts of frost, and the winter solstice hides the dormant energy to realize enlightenment.
Su Shi'an, who had just entered the other world, had a low cultivation level. It coincided with the "Late Spring Cold" disaster that swept through the sect. His spiritual veins withered and his disciples were seriously injured. At a critical moment, she remembered the record in "Secret Records of Solar Terms" that "Spring covers autumn and autumn freezes, nourishing Qi at the right time." Using herself as a guide, she used the power of the Jingzhe Spring Thunder to awaken her sleeping spiritual veins. Although she exhausted her cultivation, she unexpectedly started the path of "reverse solar terms" cultivation. After that, she understood the way of "purification" in the drizzle of the Qingming Festival to relieve the plague; she practiced the art of "growth" under the scorching sun to help farmers revive their fertile fields; and during the extremely cold winter solstice, she used Yang Qi to break through the bottleneck and break the iron law of cultivation that "do not act rashly while hiding in winter".
During the journey, she met Shen Qinghe, the Wenrun brother who insisted on "cultivating in time", and also met Lu Shuangjiang, the unruly sword cultivator who was on the "adverse journey" with her. The three of them worked hand in hand to go through the "Dashu Volcano" in search of flame crystals, and walked through the "Small Snow Ice Field" to break the maze, but they discovered that behind this seemingly natural cycle of solar terms, there was actually a huge conspiracy to tamper with the way of heaven. From passive involvement to active exploration, Su Shi'an used his mortal body to use solar terms as a blade and reverse journey as a way, setting off a storm in the world of immortality about "success to heaven" and "against heaven"
