Transmigrated as Cannon Fodder, I Get Tangled Up with the Sickly Villain

Su Jingjing woke up to find herself inside a book, as a maid to a tyrant. The tyrant was cruel beyond measure. He liked making lanterns out of human skin, took great pleasure in turning people's bones into pipa lutes, and often ordered his attendants to run around naked for his amusement. She had just taken a sword meant for the tyrant. She had no other motive; she simply wanted to die. She was also in a hurry to go back and take the college entrance exam. But the System wanted her to win the tyrant over. She thought the System had to be broken. Who could possibly win over the tyrant? Once, the tyrant got drunk and ran naked through the palace at midnight. When he woke up, he accused everyone who had seen him of lusting after the imperial body and had them all torn apart by five horses. How could she ever win over a madman like that? The tyrant believed that every concubine who tried to climb into his bed was lusting after his body, each one harboring ulterior motives. The System kept calling to her, but she closed her eyes and waited to die. Better to end it herself than let him torture her to death! But she didn't die. Why was the tyrant looking at her differently now?
