Cultivation was not something that one could excel at by simply engaging in relentless closed-door training. In fact, experiences in the world and various battles were equally important. This was one of the reasons why Emperor Zhuang had established the Merit Points Leaderboard to motivate cultivators to complete various tasks. It wasn't that the Court couldn't handle those affairs; rather, such trials could enhance cultivation efficiency. This was not unique to Zhuang Country; all countries and schools of thought around the world had similar systems in place.
Take the battle at Xiaolin Town, for example; after slaying the Grudge Ghost, Jiang Wang's Tongtian Palace produced more than ten new Path Origins. These were not achieved through Meridian Rush Practice, but naturally conceived in the aftermath of intense battle, amidst the lingering thrills.
