Wen Xinya did not expect to find out about the Korean-Chinese Alliance. That meant that it would be impossible for her to deal with them at this point, given her current abilities.
However, she asked apprehensively, "Since they're such a massive and powerful organization, it'd be a piece of cake for them to deal with the Wen Corporation. Why do they have to go to the extent of plotting against us?"
Although Si Yiyan had told her some stuff about the organization, it was all just superficial and basic information. Hence, she did not know much about them and had way too many questions.
Since she knew that they were the mastermind, she had to get a clear understanding of the situation.
