If the core idea of Lu Zhou's Group Structure Method for non-residual estimation of the modular prime numbers was from the large sieve method, then the Fourier analysis of the function on the circumference in the Helffgot's thesis was the 1% left for his "core idea".

His thoughts were flowing like a waterfall. Unstoppable!
He wrote five pages, six pages, seven pages…
