The Devouring Beast's expression turned serious, and he slowly began to explain:

"Humans and demons embark on the path of spiritual cultivation, all based on their own insights or practiced techniques, absorbing the spiritual energy of heaven and earth into their bodies. This is the beginning of spiritual cultivation. As the absorption and control of spiritual energy increases, practitioners will attempt to break through the realm, causing the spiritual energy to compress and undergo a qualitative change. Each successful breakthrough will elevate the power mastered by the practitioner to a higher level. In this process, every cell and organ in the body will be strengthened, thereby extending the person's lifespan.

The path of spiritual cultivation is like sailing against the current, each step filled with hardships and challenges, yet also filled with hidden opportunities. Beginning with the initial stage of cultivation, the warrior realm represents the initial phase of cultivation, when practitioners are just beginning to perceive spiritual energy and begin to absorb it. At this stage, their manipulation of spiritual energy is still rudimentary, capable of only simple outward attacks, let alone mastering the laws of nature. Lifespans are limited to a mere one hundred years. However, this crucial period lays a solid foundation for future cultivation, like the cornerstone of a towering building—inconspicuous yet crucial.

Once a practitioner advances to the rank of Martial Master, they can freely channel their spiritual energy throughout their body, significantly increasing their strength and speed. They can also perform simpler techniques like the spiritual shield and begin to develop a subtle sense of the laws. At this point, the practitioner is like a child who has just learned to walk, cautiously approaching the gates of the laws. Their lifespan increases to two hundred years. They begin their first steps on the path of cultivation, gradually exploring the mysteries of spiritual energy and the laws.

When a cultivator reaches the Martial King realm, spiritual energy flows freely within their body, enabling them to not only launch long-range attacks but also gain a rudimentary understanding of the laws of nature, occasionally drawing upon their power in combat. Their lifespan also rises to three hundred years. At this point, they are steadily advancing on the path of cultivation, beginning to demonstrate the true strength and demeanor of a cultivator.
