The so-called method of sustaining warfare through battle was a concept Qi Ping developed after slaying Ling Qianjue.
Initially, it was to deal with the Nascent Soul and Divinity Transformation Cultivators coveting the Tier Four Spirit Vein of the Qingtian Realm, preparing to nurture and quickly enhance the world with the essence of flesh and blood.
Later, after awakening as an Earth Immortal Druid, he did not abandon this idea. Instead, when researching the nature and laws of the world, he sometimes explored the connection between the essence of flesh and blood and the essence of the world.
So now, Qi Ping has a very clear understanding of the essence within, unlike before when he could only use it coarsely.
As a result, Qi Ping has long since developed a Magic known as the "Spirit Devouring Technique."
