Xiao Lin went to the swordsmanship hall at two o'clock, and by six, his four hours of training had raised his XP to 300. The increase depended heavily on strict standards of force and strength when swinging the sword. The slightest sloppiness was not tolerated. There was no doubt that continuously swinging the sword consumed a lot of physical energy. A pleasant surprise for Xiao Lin was that he felt less strain in his sword practice after increasing his physical fitness and physique.
To some extent, it actually proved Xiao Lin's suspicion that many of the academy's courses were actually complementary to each other. For example, the efficiency of his swordsmanship practice increased after his physical fitness improved. He might not necessarily have gained better training results if he simply set aside all other courses and invested completely in swordsmanship.
