The revised World Refining of Holy Apes and World in Sleeves, as Senior White put it, were "really easy to learn." They were specifically tailored for cultivators like Song Shuhang who lacked a solid theoretical foundation.
In the realm of cultivation, Song Shuhang could be considered a specialized scholar. When he studied blade techniques, body-tempering methods, and martial arts, his innate talent shone brightly.
Apart from blade, fist, and physique techniques, he excelled at grasping Senior White's modified magical spells.
Most cultivators typically adapted themselves to their techniques. At most, they would wait until their strength, realms, and theoretical knowledge improved before making minor adjustments to their cultivation methods for better compatibility.
However, most of the cultivation techniques that Song Shuhang practiced were tailored to suit him.
