Shin appeared in the white world for another time, lying on the ground and starting at nothingness. He was breathing quite haggardly as he was quite mentally exhausted.
This was his fourth time from what he could remember. The fourth time that he had fought against those four terrifying clones of himself and got defeated.
Even though he had fought quite better compared to the first time he tried to tackle his Promotion Quest, he was still quite overwhelmed by the combined forces of the four, particularly their perfect synergy and resourceful fighting instincts.
Shin also fought much longer and put up a good fight for every try, and he was showing a great rate of improvement. His growth could be easily seen as his fighting style continuously evolved.
From everything that he had learned from those clones, he was always fusing them with the things that he already knew.
