After all, the Void Disguise Skill was a Concealing Skill that only Nascent Soul cultivators were capable of cultivating.
Even for a Nascent Soul cultivator, it was exceedingly difficult to see through.
In such circumstances, He Song only needed to use this skill when he encountered danger.
Then, He Song would naturally be able to immediately place himself in a safe environment, without worrying about being detected by others.
Such a thing, for someone as cautious as He Song, was quite crucial.
Therefore, after listing these things as the secret skills he needed to master immediately, He Song also immediately spent a large number of spirit stones and exchanged a vast amount of Contribution Value.
Then, he exchanged all these secret skills he wanted to swiftly master from the Treasure Pavilion's treasure vault.
As for the other secret skills that He Song had already selected, but which were not immediately necessary,
He Song did not rush to exchange them.
