Archaeologist Lu Chen woke up in the sea of blood and corpses during the Huangchao Uprising in the late Tang Dynasty. Relying on his profound knowledge of history and archaeology, he struggled to survive in this troubled world where rituals and music were broken down and human lives were at stake. He gradually became a "little military advisor" who stirred up the situation from a defeated army.
However, he soon discovered that his time travel was no accident. The mysterious warlock Mr. Huntian is setting up a shocking formation, coveting the power behind time and space, and Lu Chen is the key "odd number". Caught between the torrent of history and treacherous conspiracies, he circled between the rebels, feudal towns and the imperial court, met the strange woman Xie Yunyi, and established his own power "Tracing the Source".
While using modern wisdom to solve historical mysteries and impress heroes, he is also pursuing the clues of "Time Travel" and exploring the slim hope of returning to modern times. When the world's military and ancient secrets finally meet, Lu Chen must face the ultimate choice: Shatter the void and return to the familiar modern world to complete the reunion of body and soul; or take root here, end the troubled times with your own hands, and open up a new eternity?
This is an adventure based on the richness of history, a counterattack in which knowledge serves as the strongest golden finger, and a legend of finding the way back and connections in a grand epic.
