Not to mention, in Duanmu Huai's view, the most precious treasure in the martial world is actually the secret manual of inner strength.
From the Judge's perspective, inner strength is essentially a systematic technique of using spiritual energy. Enhancing physical attributes and resistance, boosting combat power, such skills exist in many other worlds as well. For example, using magic power to enhance physical attributes, or absorbing strength and then unleashing it is similar.
But they are fundamentally different from inner strength, where the former lacks any methodical approach and is purely reliant on brute force. For example, enhancing an arm means condensing magic power on the arm to boost attack and defense, releasing spiritual energy is a direct full-body outburst. Such methods might work once or twice, but excessive use can harm the body, and may lead to contamination or transformation. In the martial world, this is referred to as going off the rails.
