When Lu Zhou was at the Cloud Domain, he had been curious about Ouyang Ziyun. As expected, they knew each other. Not only that, but based on Ouyang Ziyun's attitude and words, they did not just know each other, but they were good friends.
Since Lu Zhou had openly admitted his identity, Ouyang Ziyun also did not want to hide anymore.
Lan Xihe was shocked again. "Mr. Ouyang, you… You knew this all along?"
Lan Xihe respected Ouyang Ziyun more than Ming Xin. This was something everyone in Xihe Hall knew. He had helped her like a master and a father. From a young age, he had taken care of her and helped her deal with problems from big to small. He taught her about the profound mysteries of the universe, and she learned many things from him. In her eyes, not many people could compare to him. She did not expect him to be the Unholy One's friend.
