Cao Bi, who traveled through three years and survived in troubled times, stepped forward to save people once and awakened the tempering experience system. The more he protects people and is in danger, the stronger his foundation becomes. After being hired as a bodyguard by Lady Zhou, the widow of the Yuncheng garrison, with a daily salary of 300 taels, he escorted convoys, retreated defeated troops, broke up conspiracies, and opened human trafficking dens. He went from killing thirty-five bandits with one person to kneeling down with three hundred elite cavalry, from talking and laughing in front of two thousand elite soldiers to knocking down one hundred and forty fake refugees in one breath. Cao Bi claims to be a good young man in the nine-year compulsory education, but his actions are as fast as lightning, and he can hit the mark at the drop of a hat. When the forty-nine arrows nailed the imperial official to the pillar, and when the faceless ghost crawled into the ancient well, he was shocked to realize that this strange world was far more than what it seemed.
