Frankly, Duanmu Huai was not surprised to see Zhi Jingxiang and Kaname, but the appearance of another person was indeed unexpected for him.
"What's going on?"
He curiously asked, looking at Majeko standing on the side. However, Majeko didn't want to answer and turned her head away. Zhi Jingxiang also shook her head with her hand on her forehead, making a gesture to Kaname who then reported reluctantly.
In the end, it turned out to be Leia's doing.
In short, after the incident in the Kingdom of Seth, Leia worried that Duanmu Huai would run around aimlessly, hence, after some thought, she made a decision.
That was to build a castle specifically for Duanmu Huai at the border of Lisas, Seth, and the Free City. It would serve as a gift to him, and also a place for her to live in the future.
I have to say, Lisas indeed has money. Buying land and building a castle-like this was all done without a hint of hesitation.
