After Being Reborn Through the Book, the Apprentice Becomes Black and Clings to the Master's Upper Body

[Two male protagonists + Wearing books + Immortal style and cold master vs. Crazy and blackened apprentice + 1vs1] Qi Yufan read a novel with the same name and surname as his own, and lamented the experiences of the master with the same name and surname in it. He accidentally wore the book and transformed into the master in the book. Seeing everything unfamiliar seemed unreal, he secretly told himself: Never accept the male protagonist. As a result... "You will be my apprentice from now on. What is your name?" "Ye Nanchen" "…………" Even though Qi Yufan was unwilling to do so, when he saw this skinny boy, his heart softened and he suddenly understood why the heroine was his Bai Yueguang. He took good care of her every day. After getting along for a long time, he found that he actually had love for Ye Nanchen, but Ye Nanchen had a CP, so he quietly hid it in his heart. After repairing the barrier in Qi'an Town, a wisp of black energy escaped by chance and entered Ye Nanchen's forehead, turning him into a demon. In order to save him, Qi Yufan exploded his spiritual core and died. With the help of Heaven, he was reborn. What he never expected was that Ye Nanchen had told him that he was happy with him for nine years. When you are young, you have wishful thinking, but it will always be remembered in your mind.
