If not for the True Game's 'hack' allowing for lossless consumption, it would take Lince an immense amount of time to recover his spent Energy after every major battle at his current stage.
It's like how an ordinary person eats; there's always a digestive process to convert food into the biological energy needed for activity.
Although Lince skipped the digestive process by consuming Magic Crystals, his strength had grown so much that the energy they provided was no longer enough to keep up with his consumption.
In fact, the quality of the Energy from High Tier Magic Crystals was already far inferior to the level of the Energy within Lince's body.
If Lince had more time to slowly absorb the hundred thousand-plus High Tier Magic Crystals, he might have been able to fully replenish his reserves.
In the heat of battle, however, this method of replenishment was becoming increasingly inadequate.
