Lending their core was absolutely not a burden he wanted to force upon any of his allies. Loaning a mana heart was vastly different from lending a fast small bird for mail and payment; it required surrendering a fundamental piece of one’s own body.
Nevertheless, possessing two crystals rather than a single one would create a staggering, potentially decisive advantage in the apocalyptic battles looming on the horizon.
The moral logistics of the idea were far too muddy, so Ren forcefully shoved the thought aside. At least for the present moment.
There were vastly more pressing priorities to address first.
His mana was completely drained for the day. The immediate agenda was remarkably simple, dictated entirely by his failing biology rather than his tactical ambition: rest...
Tomorrow, he would expend half of his recovered ether to heal his crystallized pathways again, and then he would return to reinforce the dome. He would repeat this exact, grueling cycle, day after day, until his internal mana flow was sufficiently stabilized. Because in his current, heavily compromised state, his system choked by countless small shards of crystal, he simply could not risk engaging in open combat against a sovereign Light or Darkness dragon.
Stepping onto a battlefield of that caliber, with his ether constantly jamming at hundreds of different junctions, would be an absolute, guaranteed death sentence.
He desperately needed a functional body before he could execute any offensive maneuvers.
Every other tactical objective on the board had to wait.

The following morning, Ren altered the medical blueprint.
Instead of focusing his restoration efforts on his left arm, which remained a solid block of transparent crystal from the elbow down to his fingertips but retained sufficient mobility to be temporarily ignored, he decided to attack a vastly more critical threat: the small clusters of crystal that were born as energy explosions from his main channels, now seeming buried dangerously close to his heart.
These specific crystalline deposits were not visibly alarming, nor did they threaten amputation, since most were even inside the muscles, but they aggressively obstructed his internal ethereal flow at some critical, foundational junctures.
He began the agonizing process of dissolving them, isolating the shards one by one.
He made measurable progress, yet the procedure was very expensive and disheartening. There were hundreds of these microscopic fragments embedded in his tissue near the bigger mana veins, and despite their minuscule size, marshaling the absolute concentration required to melt them exacted a heavy toll. They were composed of pure high Diamond-rank mana, representing the absolute most stubborn, unyielding material he had ever attempted to transmute.
Eradicating a mere forty of those tiny deposits had already devoured a full fifty percent of his daily mana reserves.
Forty fragments eradicated, out of hundreds remaining.
And the resulting improvement in his runic control was frustratingly marginal. He estimated less than a ten percent increase in overall efficiency, ten at best.
It was still a noticeable upgrade, certainly preferable to zero progress.
But it left him staggeringly far from the biological threshold required to even entertain the thought of entering a combat zone of that level.
