In Hangzhou in the 17th year of the Republic of China, Chen Yanzhi, an antique shop clerk, accidentally came into contact with a Liangzhu jade cong. This jade cong can not only reveal the shadows of gods, humans and beasts, and manifest the earth's map, but also contains the secret of the "earth key". At the same time, a rift in the abyss broke out, and the turbid spirits were raging along with the black mist. Everywhere they went, life shriveled, and the city of Hangzhou fell into chaos. Su Lingshuang from the Shanghai Institute of Ancient Books came with the instructions from his grandfather Su Zhennan (an archaeologist) and told him that the jade cong is the key to finding the "Jiuzhou Earthline Token" and suppressing Youyuan. Chen Yanzhi and the shopkeeper Mr. Zhou were forced to embark on a journey and drove to Shanghai. Carrying the clues of the jade cong and the "Secret Records of the Earth Lines", they were involved in an adventure of guarding the Earth Lines that connected ancient Liangzhu to the troubled times of the Republic of China. The mysterious prophecy of "Searching for the Pulse Across the World" also laid foreshadowing in his heart.
