Yang Chan didn't plan on cultivating too many self-defense techniques. One Body Technique and one Swordsmanship would be sufficient. Besides, Ox Demon's Mighty Fist, Tiger Demon Bone-Refining Fist, and Flood Dragon Demon Breath Method also contained corresponding moves that could be used in actual combat.
Cultivating Swordsmanship was a way to protect himself with a weapon. After all, facing an opponent's sharp blade with his bare hands wasn't a wise move. The Demon Suppressing Swordsmanship was a complementary Martial Art, more than enough for self-defense.
His proficiency in these two Cultivation Techniques was increasing quickly. If his progress continued to be good, he could invest a few more Potential Points in them as a backup.
