Simyon's body was going through a bigger change than he expected. Due to the special item handed to him by Raze, his training was always harder compared to others.
Not only did he need to focus on increasing his Qi and stage level along with techniques, but he also needed to increase the strength of his body due to the special item, his body was different compared to other Pagna warriors.
Not only would it increase in strength as a person went through the stages, but his body would also be super refined and strengthened like a weapon. Dame told him the secret to making his body stronger was to break it down each time more and more.
Doing this, he would heal stronger than he did before. It was hardly noticeable for Simyon, these small improvements in strength, but he knew it would work because the most noticeable changes were when his body was upgraded to the next rank. Yet each time, it was harder and harder to reach the rank after that.
