I Trained A Bunch Of Saintly Disciples

Xuan Yi, a powerful figure who arrived in a new world 120 years ago, gained access to sacred texts and techniques, using them to his advantage. Forced by a system to recruit 100 disciples to leave Ghost Valley, he succeeded, though unimpressed with followers like Chu Xiaotian and Yao Ling. Known as 'Forefather', he boasted unmatched abilities, once saving General Wu of the Black Armored Army from a deadly poison, a task his disciple Yao Ling couldn't handle. 
As his legend grew, a mysterious assassination attempt on Xuan Yi unfolds, hinting at lurking dangers and hidden enemies. Will Xuan Yi confront this new threat, and what secrets does his past hold that attract such dangers?
