Through it all, Lin Mu also started to improve while also figuring out what the four immortals were best at.
He discovered that each of them had something they were better at. For example, Qian Wen was the most adept at understanding the actual battle tactics having had some training in it beforehand due to being a soldier of the royal army.
Ming Aolian and Ming Dandan on the other hand were better at simply understanding the theory behind different skills and techniques. Lin Mu reckoned since both of them were taught by the same master, it might have reflected in their learning ability as well.
Then there was Lu Xu who was best at picking out vulnerabilities in techniques. It was a difficult thing and yet it came to him naturally.
Learning these points, Lin Mu tried to expand more on them while customizing them according to each person.
