The empirical work had now entered a difficult stage. Every day consisted only of vast amounts of mechanical repetition, endlessly accumulating data in hopes of finding a breakthrough.
If someone could find another opening, that would be wonderful.
Besides, Chen Feng was only at the great perfection of Core Formation. In this sort of high-intensity empirical work, his significance truly was not great.
In this world, aside from "academic talent" and "thinking ability," "cultivation" was likewise an important factor limiting a researcher. It might not have been obvious in mathematics, but at Sky Spirit Ridge and Burning Gold Valley, such cases were everywhere.
