Yeowun was dumbfounded when he heard it. He had stayed in such a state for such a long time, but it was actually an instant. He still had the night vision mode on his sight, that proved it wasn't for too long.
'How long have I been inside in this cave then?'
[Little less than an hour, Master.]
Yeowun then sighed in relief. He was worried if he failed by not keeping within the time limit, but that wasn't the case.
'So, it wasn't as long then. What happened to me anyway?'
He couldn't understanwhat he experienced. Yeowun then asked Nano again, 'Did I just fall down? And that's it?'
[No, Master. When you grabbed the sword, dark plasma energy came in through the body. It kicked up the usage of master's neuron cells to 100% instantly.]
Human brains were activated by the individual depending on what the human was doing. There was no way the brain would be activated at 100% at any time. Nano wasn't finished there.
