The 'heavenly tribulation principles' that Senior White has analyzed are just the tip of the iceberg, but Song Shuhang himself already holds the 'Heavenly Thunder graduation certificate'—this certificate is also a form of Song Shuhang's body's understanding of 'Heavenly Thunder,' an understanding and muscle memory achieved through being struck countless times!
With the combined effects of the Heavenly Thunder graduation certificate + Senior White's version of heavenly tribulation analysis, any time Song Shuhang's clone or his Three Corpses used 'lightning techniques,' they could imbue them with a trace of 'heavenly tribulation' power.
—Don't be fooled by how timid the Heavenly Tribulation Bigshot gets in front of Senior White, facing other cultivators, Heavenly Tribulation is absolutely savage.
