Ne Zha: Shen Gongbao's Incredibly Powerful Master

[Powerful protagonist + System + Can be male or female + No heroine] I am Lin Yuan, Shen Gongbao’s master and his senior fellow disciple. I am also Nezha’s teacher, Ao Bing’s grandmaster, and his senior uncle. That day, so I could stay by Shen Gongbao’s side for a plausible reason, I sent out a clone and changed its appearance, posing as his senior fellow disciple. I stayed with him and helped him raise Ao Bing into a fine young man. Before all this, I, Lin Yuan, was just an ordinary modern young man. But by sheer accident, I transmigrated to a strange cultivation world, where spiritual energy was abundant and demon beasts ran rampant. I struggled to survive in this world, overcoming countless obstacles and hardships, and eventually became one of its great powers. Thanks to my extraordinary talent, I became the eighth Sage, a secret known to no one except Patriarch Bodhi. One day, while Lin Yuan was bored and out for a stroll, a thing called the [Get Stronger by Taking Disciples System] found him. Though the System was completely useless to him, its description left him stunned: he had actually transmigrated into the world of the animated film Nezha: Birth of the Demon Child, which he had watched in his previous life. Everything in this world was astonishingly similar to the film he remembered, yet subtly different. By chance, Lin Yuan encountered many characters from the original story. Wanting to save them from their tragic fates, Lin Yuan decided to step in and change their destinies.
