Bab 1429: Unharmed Crossing

The difficulty of controlling one person's Internal Breath was naturally worlds apart from controlling the Internal Breath of four people at the same time.

Be it the powerful burden that his Internal Breath brought to his body, even his A.I.-like brain felt a trace of pressure because of such an overly complicated situation.
