The rest of the inheritance, Jiang Chen could deduce mostly by speculation, but only a part of the core inheritance could he barely deduce.
After all, it is the painstaking effort of the Saints and the crystallization of their wisdom. If it could be deduced casually, it would be an underestimation of these Saints.
Even that portion was only due to Jiang Chen having the heritage of Shangqing. Whether acknowledged or not, the Sanqing are one entity, and the techniques share similarities.
Otherwise, even with Jiang Chen's extraordinary wisdom, he wouldn't be able to deduce the intricate parts of the Sanqing inheritance.
"Expecting the Primordial Heavenly Sovereign and Saint of Taiqing to pass on their core inheritance to me is clearly impossible; the chances are even slimmer than me successfully seizing it."
