In the fifth year after cybernetics engulfed the cornices of the ancient city, Lin Shen, a cultural relic restorer at the Forbidden City, received a strange express delivery from his late father - the Northern Song Dynasty's "Tiangang Star Map" soaked in ink. The coordinates of each star were slowly deformed on the rice paper. When he used nano-reagents to complete the incomplete Ziwei Yuan, the ink suddenly turned into living tentacles and penetrated into the wound. From then on, his right eye could see the four-dimensional cracks hidden in the cultural relics.
