An Eternal Thought: I Am Bai Xiaochun's Brother, Do You Understand?

[Sword Cultivation] [Dharma and Body Cultivation] [Beloved Brother] Traveling across the Tongtian Continent, he was reborn as Bai Xiaochun's brother Bai Yichen. Thank you for the invitation: What should I do if I am in Tongtian and don't know the plot? Bai Yichen, as a young man in the new era of China in the 21st century, inexplicably traveled to the Babel Continent and became the brother of the original protagonist, but what should he do if he only watched a few episodes of the anime? It's urgent online. It's very urgent. (PS: The protagonist is not a nanny and has his own path.)
