Hearing Elder Yi's words, Lu Yi sank his consciousness into the Sea of Consciousness.
Lu Yi already knew the basics of opening a Soul Aperture.
Like a Soul Core, a Soul Aperture formed from a Spiritual Aperture required ample liquid Soul Power in the body.
After that, forming a Soul Core meant compressing that liquid Soul Power again and again until it gradually became a solid core, then setting it spinning until it reached equilibrium and stability within the body. Its pull would then automatically absorb the surrounding Heaven and Earth Essence of the same attribute.

Of course, a Soul Core was usually condensed only when someone broke through Level 90 to become a Titled Douluo, while a Soul Aperture could be opened at level sixty.
And Soul Apertures far outnumbered Soul Cores. They could also convert energy of different attributes for their owner's use. From those angles, their advantages were clear.
