Invincible Overlord

Invincible Overlord is an urban supernatural web novel by Feng Xiangyu, serialized on Baidu Novels starting in 2015 and completed on December 4, 2021. It runs 525 chapters and roughly 1.647 million characters. The story centers on Lin Yu, a senior at TianTai Middle School, a key high school in Zhonghai City. After a romantic setback deals him a blow, he unexpectedly obtains a system called the Invincible Overlord, and his life path is completely transformed. The system has scanning and assessment functions that quantify others' combat power, allowing Lin Yu to see how strong his opponents really are. In his eyes, foes like taekwondo black belts and karate champions are nothing but trash with a combat power of five, and he defeats them one by one. He is then introduced by an old man around him to a perilous place called the Bloody Purgatory for life-and-death training, where he clashes with ferocious squads such as Blood Wolf, Blood Thorn, and Blood Fiend, using the system's scanning ability to gauge the gap between himself and his enemies and survive. As the plot advances, he encounters the hidden side of the world he never knew, has fierce conflicts with Elders Shi Feng and Chen Tianlin of the Tiangang Sect, and steps in to rescue Fu Tianxiang. He also makes a ten-year pact with the even more powerful Tianxuanzi. Later in the story, Lin Yu awakens the heroic legacies of parallel worlds in the Legacy Tower, and faced with three options in descending order of power—Knight Agito, Knight Zi-O, and the Imperial Armor—he ultimately chooses the Imperial Armor legacy, which outsiders regard as a trap. The book follows system growth and combat power escalation as its main thread, blending school, urban, martial arts, and fantasy legacy elements with a brisk pace—a typical long-form urban supernatural power fantasy.
