Nezha: Shen Gongbao's Super Powerful Master

[Protagonist is strong + system + can be male or female + no female protagonist] I, Lin Yuan, am Shen Gongbao's master and his senior brother. I am also Nezha's teacher, and Ao Bing's master and his senior uncle. That day, in order to stay by Shen Gongbao's side in a reasonable way, I sent a clone, changed his appearance, stayed by his side like a senior brother, and accompanied him to cultivate talents with Ao Bing. Before this, I, Lin Yuan, was just an ordinary modern young man, but I accidentally traveled to a strange world of immortal cultivation. In this world, spiritual energy is abundant and monsters are rampant. I struggled in this world, overcoming obstacles and suffering, and finally became a powerful person in this world. With my powerful talent, I am the eighth saint that no one knows except Patriarch Bodhi. Suddenly one day, when Lin Yuan was out for a walk out of boredom, a system called "You can become stronger by accepting apprentices" found him. Although this system was of no use to him, after describing the system, he was shocked to find that he had actually traveled to the world of an anime movie "Nezha Demon Boy Comes into the World" that he had watched in his previous life. Everything in this world is strikingly similar to the plot of the movie in his memory, but there are subtle differences. By chance, Lin Yuan met many characters who had appeared in the original plot, and in order to save them from their tragic fate. Lin Yuan decided to save them and change their fate.
