After university professor Lu Xiujing passed away suddenly, he transmigrated into the cultivation world as a nominal elder with the lowest cultivation level who was despised by everyone. Facing four marginal disciples labeled as "good-for-nothings"—a dragon tribe outcast, a violent swordswoman, a pedantic Confucian scholar, and a drowsy little girl—he did not choose to give up, but instead awakened the "Strongest Master" system. The system bestowed upon him the "Master is Invincible" halo, setting a unique path to becoming strong: as the disciples grow stronger, he grows stronger.
