"Mind Protection" was not difficult to learn. Ling Tian and the others needed only a few years, while the younger generation, like Ling Yu, would need only several decades to nearly a hundred years. Ling Tian planned to stay here for two hundred years, which would be more than enough.
Of course, although the technique was not difficult to master, it was based on Soul Law Power. In other words, the deeper their comprehension of Soul Law Power, the more powerful the technique would be. But comprehending Soul Law Power was no easy matter for them.
That meant mastering the technique and putting it to use would not be simple, either. It was probably impossible in a short time.
Comprehending Soul Law Power in just two hundred years would be extremely difficult. Still, Ling Tian had already studied Soul Law to some extent, so he had a foundation. If he worked hard at it, he could make a little progress.
As for the other technique, "Soul Tremor," Ling Tian and the others had studied it as well. It was exceedingly complicated, and they probably would not master it for a long time. Moreover, this technique was also based on Soul Law Power. In short, the only proper course for Ling Tian and the others was to diligently comprehend Soul Law Power.
Of course, Po Qiong had already made copies of both techniques, and Ling Tian still had a Nine-Colored Soul Crystal that could radiate Soul Law Power. Once they returned to Beixuan, he could continue his studies.
And so, Ling Tian and the others worked hard to comprehend Soul Law Power, while Tan Tai Chang Feng helped Tan Tai Xiao Lin blood-refine the Order Divine Artifact spear. Each of them had their own task to focus on.
