The protagonist Xiao Xuan tells you the answer: While others were still struggling to find the skills, he was already waiting under the cliff for the magical skills to be born. While the major forces were still recruiting troops, his future invincible God of War, the richest businessman, and the peerless saint had already been "cut off" by him in advance and became his confidant. While the heroes are still fighting bloody battles for one city and one place, he has already laid a dragnet to control the rise and fall of the dynasty and watch the changes.

In the end, even her people and the country became his bag. One sentence summary: I, Xiao Xuan, the reborn person, the troubled times in your eyes are just my script!
