The Sea of Life, located below the navel, was the collective term for the Bitter Sea and the Life Wheel. It was where the source of magical power in the body's mystic realm method resided.
Thus, the first minor realm of the Sea of Life Realm was opening the Bitter Sea.
An ordinary person's Bitter Sea was black, representing death within life and death, constantly eroding the Life Wheel. The Ancient Holy Body's Sea of Life, however, was golden, brimming with vitality at a glance.
This was an anomaly displayed by the Holy Body at the very beginning of cultivation. This uniquely blessed physique was also why a fully realized Holy Body could rival those who achieved an alternative Dao, and why those who achieved an alternative Dao could even contend with Great Emperors.
The reason the Holy Body had the prefix "Ancient" was because it had only dominated the world during the Ancient Era. The rules of heaven and earth were no longer suited to the Holy Body's cultivation.
The Holy Body's Bitter Sea brimmed with vitality, while its Life Wheel lay dormant. Furthermore, the Holy Body's Bitter Sea was incomparably tough, requiring vastly greater resources than ordinary people to open it.
Beyond that, the Holy Body's later cultivation also consumed massive amounts of resources. Upon reaching the Four Extremities Realm, one would even have to face the curse of the Heaven-Reaching Nether Treasure...
"But the problem is, I don't seem to have that issue... Could it be because I made this Holy Body myself?"
Adam looked at the Bitter Sea he had opened with incredible ease. After thinking for a moment, he stopped dwelling on it.
As he had said, there were not enough samples. As long as there was no problem with his realm, that was fine.
