Stop practicing Martial-Arts?

Shin was told to rest for a few hours so that he could recover his peak condition, but it was already dark outside when he woke up.

"D*mn! So, I fell asleep for that long, huh? I guess I am really too tired this time," muttered Shin as he tried to get up from his bed.

The intense headache that he was feeling earlier was already gone, so he was able to get up without problem. But his entire body was quite stiff due to staying on the bed for quite long. With that, he did some body stretching to relieve that stiffness. But didn't dare to do his usual training routines since he was not sure if it was going to affect the current state of his dantian.

When he was finally able to move his body without having much problem, he immediately walked out of his room and quickly went to his Master's place.
