Of course, Chu Nan knew very well that doing this was equivalent to completely exposing his use of his Internal Breath to the other three, but he did not think there was a problem.
His exquisite use of his Internal Breath and precise control of spatial energy mainly came from the powerful brain that was equivalent to an A.I. he had obtained after the mutation. His sensitivity to data and super precise control were things that other martial artists could not replicate.
Even if he knew his various actions very well, it was extremely simple to learn.
Moreover, this complete openness was mutual. He opened himself to the other three, and the other three actually opened up to him too.
Through this unreserved interaction between Internal Breaths, Chu Nan could actually pry into a portion of the secrets hidden in the other three people's Internal Breaths.
