Lu Ren, a transmigrator, is burdened with the Time Pagoda. A single moment in the outside world allows for decades of bitter cultivation inside the pagoda. However, born with a trash-tier bloodline, he is regarded as a useless person by the entire sect, enduring endless mockery and suppression from his fellow disciples. By a stroke of fortune, he becomes the disciple of Saintess Yun Qingyao. Relying not on innate talent, but solely on infinite bitter cultivation, he defies the heavens to break through, storms the sect tournament, delves deep into secret realms to defeat formidable enemies, and challenges major sect geniuses and eliminates hidden assassins along the way. After countless trials of life and death, he finally unlocks the sealed secrets of the ancient martial artists, breaks free from the shackles of his bloodline, and walks a path to the pinnacle of martial arts forged entirely by perseverance rather than talent.
