Several factors needed to be considered before choosing a cultivation technique. Grandmaster Xu reminded him about that in the letter. Ouyang Biya also informed him about it, and Han Taiyang reminded him as well.
His constitution was one of the factors. A technique that was in harmony with the constitution would yield a better result and faster breakthrough without sacrificing the foundation.
Then what kind of cultivator he wanted to be was also an important factor, the path. The combat path, craftsman path, alchemy path, or even the formation path. Depending on the path, one needed a specific technique that would help them in that path.
Of course, there was a technique that might be suitable for several paths, but that was a rare one. That was how the Thousand Vows Pavilion taught its disciples. It was kinda different from the sects in the Sacred Realm, as Ouyang Biya mentioned.
