"Only Ji Ziyin can answer it, right? I bet she can solve it in an hour."
"Ji Ziyin is the Ji family's genius of this generation. It might take less than an hour if she tries. I'll bet forty minutes."
Almost everyone was whispering about Ji Ziyin.
Compared to this question, the people who came to the banquet were more curious about the strength of the Ji family's new generation of black gunpowder geniuses.
"Elder Zhong, how long do you think it will take Miss Ji to solve this question?" someone beside Zhong Yiliu asked him.
