Douluo: Twelve Years of Secluded Cultivation, Starting by Crushing Tang Hao

Transmigrated into the Douluo Continent as a six-year-old child, Cao Kun is adopted by Zhao Wuji and joins the Shrek Academy. Upon awakening his martial spirits, he gains access to a sign-in system that grants him two powerful abilities: the Body Martial Spirit and the Chaos Bell. Choosing the path of secluded cultivation for twelve years, Cao Kun silently advances to level 99, achieving the status of a Limit Douluo. His true strength remains hidden until Tang Hao arrives at the academy, seeking revenge against Zhao Wuji for allegedly mistreating Tang San. Just as Tang Hao prepares to unleash his wrath with the Clear Sky Hammer, Cao Kun steps forward. With a single punch, he sends the legendary hammer flying and effortlessly suppresses the Title Douluo. Shocked by this display of overwhelming power, Tang Hao questions how such strength is possible. Cao Kun simply replies that being strong at Shrek Academy is only reasonable.
