In the late 1980s, Hong Kong Island was in turmoil, with dragons and snakes mixed together. Han Xun, who traveled through time, appears to be a down-and-out small vendor who hangs out in the back alleys of Yau Ma Tei, making a living by helping neighbors repair watches and electrical appliances. He seems to be indifferent to the world, but in fact he is deep-minded and takes care of himself every step of the way.
An accident caused a strange "skill intrusion" system to appear in his mind. This system does not issue tasks or reward points. It will only randomly "stuff" top skills from various fields into his mind when he makes a choice - from the ballistic tracking of police officers, to the street fighting of underground forces, to the stable techniques of a first-class cardiac surgeon, and even the top psychological games of charlatanism.
Hong Kong Island is a small place, but it is a hero's land and a hero's grave. The "dragon crossing the river" among the police regarded him as a mysterious white glove with both wisdom and bravery; the "smiling tiger" in the society respected him as a "white paper fan" who had no plans; even the business giants who had been in Hong Kong for many years were shocked to realize that this humble young man was actually the mastermind behind the financial storm.
Han Xun never does anything wrong, he just wants to maintain an inch of peace in this cannibalistic world. He used "coincidences" one after another to resolve crises, and used more sophisticated layouts to crush the enemy. Everyone thought that he was a chess piece wrapped up in fate, but little did they know that this chess game had been in his hands since the first day he set foot on Hong Kong Island.
When the shadow of the Kowloon Walled City intersects with the neon lights of Victoria Harbor, an era of "folk wise men" quietly begins.
