Lin Mo, who was ranked last in his senior year of high school, activated the mysterious system when his grandmother was seriously ill, bullied at school, and in a desperate situation when he was dying in the hospital.
From then on, wildfire ignited in those always downcast eyes. During the day, he is a poor student trying to fight back; at night, he is the new king rising from the shadows of Binjiang City. From the establishment of the underground order on campus, to the expansion of gray industries, to the rise of a business empire - he uses the 3 seconds of future predicted by the system to make the cruelest and most accurate choice at every fork in the road of destiny.
However, power comes at a price, and every upgrade of the system burns his life. When wealth and power reach their peak, the countdown to death also quietly approaches. The three women who love him deeply - the righteous prosecutor Su Yuqing, the business genius Qin Yue, and the guardian of the Nine Gates Bai Li - each try to save his life in different ways.
This is a race against time, a game of light and shadow. When the final showdown comes, facing his destined opponent Ye Wudao, Lin Mo must answer: How long can a legend ignited with a short life leave a shadow in history?
From the corner of campus to the top of the world, from humble student to shadow master, this is a story about redemption, price and inheritance.
