Though the Three Truths Method had already declined, a starving camel was still bigger than a horse. The books left behind covered everything imaginable. Setting aside its three major paths of talismans, treasures, and body cultivation, there were even texts on things like "law puppets" and medicine.
The only drawback was that none of these books came with introductory guides or detailed explanations. They were filled from start to finish with obscure references for readers to comprehend on their own. This was one of the common flaws of sect-based inheritances: setting learning thresholds to prevent secret teachings from leaking out.
Such thresholds had almost no drawbacks in a normal sect. With a master guiding disciples step by step, they were actually easier to understand than other teaching methods. Different explanations and understandings of the same references also left learners ample room to awaken to the Dao.
Unfortunately, the Three Truths Method was no ordinary sect now. After a catastrophe that had nearly wiped it out, Ma Chao, the sole survivor, was the only one who understood its methods. As a junior disciple of the previous Three Truths Method, Ma Chao naturally did not possess a thorough understanding of the "methods." Coupled with the limits of his own talent, Ma Chao's current "methods" contained major misconceptions, and he had even unknowingly passed those erroneous "methods" on while teaching everyone.
In the original story, Gao Hao Guang had taken a huge detour because of this and only returned to the right path after Jiang Mingzi taught him.
But Chu Ke had no such bottlenecks, because he had cheats.
So-called awakening to the Dao was merely thinking about "methods."
Even a monkey completely devoid of talent for enlightenment could eventually comprehend the Dao if it kept trying over an infinite amount of time.
