Meeting point
It was only obvious that Shane could defeat Jason and his soulbonds with his overwhelming strength.
This made him feel even worse when he adjusted his strength to be on par with a peak-Master rank because his combat awareness, experience, along with his proficiency in martial art techniques were in a different league altogether than Jason's.
Nevertheless, Jason had learned a lot through just one spar with Shane and his [Devious Swordmaster] technique was already reaching the familiar mastery that came immediately after the basic mastery.
Thanks to his mana eyes and Shane demonstrating the Tier-2 martial art technique in detail, Jason didn't have any problems while practicing it.
He was also able to fix his flaws shortly after Shane pointed them out and improve himself.
Other than sparring with him occasionally, Shane decided that it was time for him to teach Jason about blacksmithing more in-depth.
