Tang Luo, an ordinary college student, whose biggest hobby is complaining about the irrationality of the world. Until one day, his ex-girlfriend Lin Xueer, who had been separated for three years, suddenly returned, followed by a group of mysterious strong men in ancient costumes, who said, "Welcome back to the Saint."
What's even more outrageous is that Lin Xueer said to him apologetically: "I'm sorry, I was afraid that you would get involved in my world before I left. Now I am returning to Jiutian Continent. I have been protecting you secretly for the past three years."
Before Tang Luo had time to complain, a mechanical voice sounded in his mind: [Congratulations to the host for activating the "Complaint Energy System". Every time you successfully complain about an unreasonable setting, you can plunder the opponent's luck value. ] From then on, Tang Luo discovered that this world was far more bizarre than he imagined - his roommate was a demon lord, his mentor was a hidden swordsman, and even the cafeteria aunt was a strong person in the tribulation period who had sealed his cultivation. And all the strong men revolve around one woman - his ex-girlfriend Lin Xueer.
While others were vying for the Nine Heavens Goddess' luck, Tang Luo relied on his complaints to plunder her. The more he complained, the stronger he became, and the more he complained, the more invincible he became.
