Vendetta against his wife?

Long Jie could refuse Alcina help but he didn't. Deep down, he knew she didn't come to him for help. She needed something else from him. But he didn't know what. 

Firstly, she approached his drunk and sad wife that day. Not only that but also stayed by her side until he came. He didn't know what was her intention behind protecting Zhenyi that night but he had an idea she was there for him. 

Then she called him for help when she could have asked anyone...

"I will help you, Alcina," Long Jie said to her after a while.

"But you have a condition. I get it." Alcina wasn't crazy enough to think that Long Jie would help her for free. He surely had something going on in his head. 

"How do you know?" Long Jie asked her immediately. He had to say that the girl was smarter than he had expected.
