Twelve O'clock: the Secret of Heaven Flows

In the late Zhenguan years of the Tang Dynasty, the stars in the sky above Chang'an City changed suddenly. After observing the celestial phenomena at night, the Qintian Supervisor collapsed from convulsions. Before his death, he only left the names of twelve mysterious hours. An epidemic breaks out in the Zi period, a ship sinks in the Chou period, a fire burns in the Yin period, and there are academic malpractices in the Mao period... Disasters are like poisonous ivy lingering around for twelve hours, pointing directly at the lifeline of the dynasty. When a widower cut open her child's first corpse, she was surprised to find a star map tattoo; the descendants of the Onmyoji Division went to the ghost market at night and bought a "time plate" that could glimpse the future; a failed scholar was caught in the Mao Shi Examination Hall and uncovered a prophecy that predicted the overthrow of the dynasty; and the veteran border guard returned to Beijing to report on his duties and found that the transfer order issued by the Ministry of War was covered with an old seal that had been destroyed three years ago... When the twelve o'clock disaster stars form a regicide formation, can they solve the regicide engraved in time before the sundial shadow catches up with the dragon chair?
