The most ruthless imperial master in his previous life, after his rebirth, he chose to become a tyrant taught by his own hands in his previous life. This time, she approached him as a "palace maid sister" and used thirty years of imperial skills to teach him again. The difference is that in this life she took "loyalty" out of the curriculum and only taught him coldness, calculation and how to destroy everyone. She wanted to turn this man who was supposed to be a tyrant into a sword loyal to her alone. When all the civil and military officials in the dynasty were fawning over the prince, no one would notice that in the corner of the imperial garden, a sister of a waste queen was teaching a five-year-old abandoned son how to drive a wedge between father and son with just one sentence.
