The Golden Dragon Empress's pretty face flushed red.
Yet, firstly, she was under the Red Moon spell, making it impossible for her to refuse Zhou Heng. Secondly, after spending so many days together, to say she wasn't moved by this man would be too self-deceptive.
Of course, without the Red Moon spell, her Dragon Clan pride would never allow her to pursue Zhou Heng unless he made the first move. However, since she could only follow this man for the rest of her life, she had a mentality of reckless abandon, which made it easier for her to fall for Zhou Heng.
The kiss left her dizzy and disoriented, nearly causing her to collapse. Fortunately, Zhou Heng held her, preventing a fall. Even so, after the kiss, she leaned against Zhou Heng as if her body had turned to jelly.
Zhou Heng was simply too excited, hence the sudden kiss. It wasn't that he had any particular thoughts about this Dragon Clan Empress, and after the kiss, he intended to release her.
