I put my sword on my neck at the beginning, and I relied on technology to fight my way through the Tang Dynasty! Li Xuan, an unlucky man from science and engineering, found himself shackled to death row and placed in the execution ground of the Tang Dynasty Palace as soon as he traveled through time! What's even more outrageous is that the original owner was actually an unclean "fake eunuch" who sneaked into the palace. This is a capital crime for the Nine Clan! Seeing that the ghost-headed sword was about to fall, and on the thin line between life and death, Li Xuan suddenly thought: "I can make ice!" The heat was unbearable, and the whole place was in an uproar. In order to survive, Li Xuan had no choice but to fight! Use modern knowledge as a bargaining chip and scientific principles as weapons. Now that we are here, why not completely change this era? As a result, the figure of a "fake eunuch" began to be active between the shadow and the light of the Tang Dynasty: papermaking was improved, printing was innovated, knowledge was no longer exclusive to the powerful; steel and iron were forged, weapons were forged, and military equipment was quietly upgraded; when the first rough but roaring steam engine model was born in his hands, the industrial dawn of the Tang Dynasty was actually ignited by a death row prisoner! From a prisoner on death row to a celebrity in the imperial court, from secrets in the palace to games in the court. The powerful are wooing them, enemies are surrounding them, and murderous intentions are everywhere. The empress Wu Zhao came to the throne with his assistance, but her eyes turned red when he married Pei Qingwan: "Back then, you said you would only be a fake eunuch for me, why did you break your promise?" On one side is the affectionate empress, and on the other is the female doctor who is with him in life and death. Where will Li Xuan's technological empire and emotional whirlpool lead the Tang Dynasty? Science and technology prospered the Tang Dynasty, and the Industrial Revolution was staged in Datang ahead of schedule! Watch how a "fake eunuch" uses science to leverage history, and create a legendary age of his own in the gap between power and love!
