After practicing magical skills, he defeated fame and fortune, so he jumped out of the conflicts in the world; he defeated emotions (happiness, anger, sorrow, fear, love, evil, desire), so he could kill his brothers as he pleased and feel at ease. Of course, when he overcame everything and faced real life, he realized that he was just a drop in the ocean, and he would eventually return to dust after a hundred years. There is no trace of the ambition left, only despair and pain. So he lived in a deserted cave. He likes a man named Yang Lianting, maybe it's just a kind of sustenance after being extremely bored. Although Yang Lianting is physically weak, he has a strong personality. They looked like a couple, and seeing him injured, Dongfang Bubai was filled with anger. He even put his friend of many years to death, but for him, he had seen through the brotherly love and everything was casual. Maybe he is not in love with Yang Lianting, but regards him as his incarnation and sustenance. So when others hurt Yang, he felt pain. But facing real life, extreme despair and pain did not take his life, which shows how strong he is. He lives in a cave and his mind becomes calm. He is waiting for the person far below the West Lake to come and end his pain and life, which is also repayment. This is his own destiny. If that person doesn't come in his lifetime, he will wait his whole life. Therefore, Dongfang Bubai is the most profound wise man in the book and should be respected by people inside and outside the book.
