Good News: Awakening System, But I Keep Doing Stupid Things

After transmigrating as a lowly servant, Zhang Chunan accidentally activates a system that rewards him with cultivation, special physiques, and techniques for completing stupid tasks. His first mission is to trick the Demon King's Saintess Leng Ruofang, only for her to recruit him as her exclusive sword slave. Along the way, he completes absurd tasks like refusing heavenly treasures, angering the Saintess, and forcing a public display of equality, earning rich rewards such as the Ten Thousand Swords Technique and the Eternity Body while meeting characters like Qing Luan, Xuan Yuan, Auntie Zhu, and Luo Wanwan. As his own secrets gradually reveal themselves, he falls in love with the aloof Saintess and becomes entangled in conflicts among various powerful factions.
