Speaking of which, "Knowledge of Earth's Advantage" turned out to be the nemesis of the Earth Escape Technique. The main issue was that Chu Xuan had never thought someone might be hiding underground to spy on them.
Now that he is on guard, it will be much harder for others to use the same trick against him again.
Since the essence of "Knowledge of Earth's Advantage" is gaining a deeper understanding of the earth, could it possibly aid in cultivating the Earth Escape Technique?
With this in mind, Chu Xuan began to try practicing "Knowledge of Earth's Advantage" first. Once he achieved results, he would circle back to the Earth Escape Technique.
Interestingly enough, after fully mastering the first level of the former, the latter was no longer so difficult to comprehend.
In three years, Chu Xuan truly mastered the Earth Escape Technique.
