Starting as a Slave, You Are Not Allowed to Take the Imperial Examination? I Will Kill the Powerful with My Pen

(Emphasis on imperial examination + Emphasis on power strategy + Middle group portrait + No golden finger + Time travel) A modern soul is trapped in the body of a slave, climbing from the bottom of the family to a position of power under one person. There is no system, no plug-ins, just a heart unwilling to be crushed and a set of bones willing to fight to the end. The imperial examination is the blade, and the court is the bureau. It takes ten years to sharpen a sword, just for that day. Let the high man kneel where he once knelt.
