Jiang Yunfeng said a great deal, but his point was that a spirit creature whose cultivation level and essence of life resembled those of its Spirit Tamer would occupy roughly one-third of the Spirit Sea's capacity.
This had nothing to do with strength, breed, or attributes. Instead, it was more closely tied to the essence of its true spirit and its potential for growth.
"However, when an Earth Rank Spirit Tamer's spirit essence transforms, the burden of constructing a spirit body decreases. In other words, the Spirit Sea can hold more spirit creatures!"

"Earth Rank Spirit Tamers have an additional advantage when keeping Human Rank spirit creatures."
"Back when you were at the tenth transformation, you could establish Spirit Communion with three Human Rank spirit creatures whose essence of life rivaled that of tenth transformation experts. Once you reach Earth Rank, even without any improvement in your physique or Spirit Sea, that number rises to six."
"What's more, advancing to Earth Rank inevitably improves your Spirit Sea, so the actual number can reach nine or more..."
"Converted into a different combination, that would be one Earth Rank low-grade spirit creature, likewise at the first transformation, plus three Human Rank supreme-grade spirit creatures, and another nine mid-grade or high-grade spirit creatures..."
