Cultivating with the use of essence gems before reaching a certain level of power, was only possible for somebody like Daniel, who thanks to his increased speed in the refinement and healing of his body, was able to prevent the excessive power from turning him into a meat paste that decorated the cavern's walls.
While he cultivated, the seemingly endless amount of essence condensed into the gem would wash into his body tirelessly, wrecking it beyond recognition, and fighting the healing essence that was desperately trying to keep everything together.
In the past three months, Daniel had been forced to stop this process more than once, as he did not want to risk going insane from the excruciating pain.. Unfortunately, the only way he had to take a rest, was to dig the dissolving gem out of his stomach with his own hands.
