Yun Rao passed through and became the cannon fodder who died the most miserably in fantasy novels - the demon king's newly married poisonous concubine. The original owner poisoned the Demon Lord on their wedding night, and his cultivation was abolished. He was thrown into the Ten Thousand Gu Cave and is now being eaten by poisonous insects. When he was dying, a cold system was bound: [Ultimate survival mission: within a month, let Demon Lord Suye's favorability towards you reach 100. Initial value: -99. Penalty for failure: obliteration.
Looking at the poisonous centipede squirming on his wrist and the blood-red negative value, Yunrao silently picked up the "Fragments of the Ancient Poison Scripture" that the original owner had placed on the corner of the table.
At the feast of the demon realm, all the demon kings provoked her, and she offered a "small gift" with a smile. The demon kings in the hall were all in pain, but he was the only one sitting on the throne, playing with the wine glass with his fingertips, his eyes as dark as the abyss.
The allied forces of the Immortal Sect were pressing on the border. She stood on the city wall, raising her bare hands lightly, and the colorless poisonous mist swept thousands of miles, and the enemies fell in pieces. He held her chin and breathed dangerously: "My poisonous concubine, how many more surprises do you have?"
Later, the three realms were shaken, and he killed immortals and gods for her, drifting in a sea of blood. Yunrao looked at the favorability value on the system panel that had already exceeded the limit and was still beating wildly, and fell into deep thought.
"System, is his favorability test... Broken a long time ago?"
No one knew that the scale that once dropped to negative values was pointing to the unmeasurable abyss of madness from the very beginning.
