Bizarre murders have occurred one after another in Linhai City: a history professor was hanged in the "White Gate Tower", a grain and oil boss died in a replica of Dian Wei's death, and an office building executive was trapped in the "Eight Array Elevator" - only jade pendants from official kilns of the Eastern Han Dynasty, bronze arrowheads and other antiquities from the Three Kingdoms were left at the scene, but there was no trace of the murderer.
Chen Yan, a top student in the history department and a part-time suspense blogger with millions of fans, used details from "Three Kingdoms" to expose the police's "copycat crime". The conclusion: the jade pendant contains space-time radiation, and the arrowheads come from the battlefield of the parallel Three Kingdoms! He teamed up with archaeologist Lin Shu to conduct an in-depth investigation and discovered the hidden villain - university tutor Zhang Qi. Three years ago, a meteorite fell, and Zhang Qihuo's fragments opened a space-time channel, hoping to lead Cao Cao's army from the 13th year of Jian'an to cross the border and replace modern times with the order of the Three Kingdoms!
When Zhang Liao led his cavalry to break through the high-speed defense line, Xu Chu opened the door of the police station with a heavy halberd, and Cao Cao announced in the old city that "the new Xudu will be the capital". Chen Yan did not have a golden finger, but relied on historical knowledge to break the situation: he used Guan Yu's arrogance to set up an ambush to defeat the enemy, instigated Xu Shu's rebellion to gain access to the weak points of the passage, used Zhuge Liang's Eight Formation Diagram to crack the method to stop Cao Cao's army, and even used the picture of modern civilization to persuade Cao Cao to withdraw his troops.
Police drones attacked the Three Kingdoms Archery Tower, volunteers equipped with body armor and Zhao Yun's personal soldiers. A confrontation between civilizations that spanned a thousand years finally came to a close in the hands of Chen Yan. But the museum's bronze mirror suddenly lit up, and next to Sun Quan's figure in the mirror stood a mysterious man in a suit - a new cross-border crisis was already dormant in the darkness!
