The method would be too wasteful. It involved using water from the Element Well to concoct pure water-elemental energy, then using the water from the Element Well to nurture the Ice Sealing Frozen Carp in order to obtain pure ice-elemental energy from it.
There was no question that the second method was more convenient.
However, Lin Yuan still chose the first option because the Ice Sealing Frozen Carp would absorb a portion of water-elemental energy when it turned water-elemental energy into ice-elemental energy.
Every drop of water from the Element Well was invaluable. Unless it was absolutely necessary, Lin Yuan did not want to waste even a single drop.
Since he had made his choice, Lin Yuan added Grasswood Fountain Water into the amazonite tank before he placed the Ice Sealing Frozen Carp into the tank.
Grasswood Fountain Water contained vitality.
