Ye Lingchen fiddled with the weapon in his hand and was already beginning to think of its utility value.
He initially felt that any knowledge other than Kungfu were just auxiliary skills, but his thinking had changed dramatically.
Those skills were fundamental!
Regardless of how skilled one was at Kungfu, that strength belonged to only one person. Even if he could pass down the Kungfu, how many people would be able to learn it? On the off chance that they could, it still took time, and there was always the concern that one of them might give up midway.
Other skills were different because they strengthened one's ability in the short-term. It could also possibly be a way to increase one's power.
For example, Ye Lingchen would not dare to act so brazenly earlier if there had been no formation. It would not have been that easy to kill an enemy that was much stronger than him.
