Without a doubt, Zhao Youyue was impressed by an elite scholar such as Wang Zongchao. Even with the help of "Xu Jing's card," she was not even close to surpassing him in terms studying. It was apparent that his standards and hers were not on the same level, and it was not because she was not hardworking enough.
When Wang Zongchao asked Zhao Youyue how she managed to get good results for English, she could not simply say that she relied on her "Yu Shengfan's card," so she decided to go along with the premise that she played lots of foreign language games. She preferred to play them in their original languages, so she had no other choice but to master the English language...
This was the actual reason why Yu Shengfan was good with languages from several countries. But in reality, it sounds cooler when Zhao Youyue says it out herself.
