The most obvious change Jason perceived was his exhaustion.
This was only obvious and based on the way he was currently feeling, his body could be compared to a machine that worked in power-saving mode.
'So...how can I decide whether I want to work at full speed or in the power saving mode right now...?' He asked himself with the desire to move.

While sustaining everything necessary with his soul threads, a few more hours flew by before Jason was unable to stay awake anymore.

Yet, he had forced himself to stay awake, to not rest for a single moment, until they finally found a secure location where nobody would be able to find and hunt them.
