At first, it was quite difficult to split his thoughts, showing some of them at the front to trick the voice and hiding the rest at the back of his head. But nothing he will be unable to deal with. After all, he has memories (from the first person perspective) how he successfully controlled hundreds of clones and none of them were caught for an enormously long time. Yes,that is not the same as to actually have those skills, but it is still quite helpful. Considering that there is literally nothing else to do in the current situation, He Xuan carefully digged back those fragments, which triggered some new ones to appear throughout the dreams, previously hidden. Which is also an interesting phenomenon he didn’t pay attention before and needed to explore later.
