The Qi Sea is where the spiritual energy resides, and all those who cultivate should learn to utilize their own Qi Sea.
And to utilize it, first, you must see it, you must understand it.
The second level of the Qi Consumption Technique is precisely this.
Indeed, the reason why the Qi Sea uses the term "sea" is because the Qi Sea is vast and wide enough!
People in the Demonic Way are different from those in the Righteous Sects. Those in the Demonic Way always attempt to form their own nature, and the Qi Sea is the foundation for their usurping of nature's spiritual energy.
Simply put, the so-called "Qi Consumption" is the swallowing of spiritual energy, and the swallowing into the Qi Sea.
But since ancient times, there have been many cultivators of the Demonic Way, and yet no one has ever heard of anyone filling up their Qi Sea.
Therefore, in the perception of those who cultivate the demonic way, the Qi Sea is often seen as endless.
