When the sky above Qin Shihuang, Tang Taizong, Ming Chengzu, and Han Emperor Wu were shrouded in giant screens at the same time, the four dynasties could clearly see each other's territories in a cross-time and space live broadcast - but they did not know that this "miracle" was an observation experiment of a higher civilization. Under the sea of Chaozhou, the sleeping ancient ruins "Recording Stone" awakened due to the noise of civilization and began to release invisible erosion: the Qin army heard the ringing in the ears of metal, the Tang Dynasty scholars dreamed of geometric abyss, the cannon sprouted evil patterns, and the Han ballads were tampered with during the singing. What's even more terrifying is that the ruins are resonating with human fears - every attempt to fight against pollution is accelerating its awakening. Is Jin Yiwei's Xiuchundao slashing at the infected person or the sacrifice? Can Yuan Tiangang's prophecy decipher the agreement from Xinghai? When the light from the bottom of the sea outlines a terrifying matrix covering hundreds of miles, the four dynasties face the ultimate choice: become experimental data under the sky observation, turn into new ruins when the ruins awaken, or use the final game of law, faith, violence and knowledge to carve out a bloody path for human civilization? This is a shocking collision of Eastern history and hard-core science fiction, an epic of the survival and death of the four great dynasties under double gazes.
