Out of the four days of wall buffer they had expected to have after the Shadow Dragon battle, a little over three and a half remained on the counter.
Factoring in the new shadow-boosted drilling speed, that buffer translated to slightly less than sixty hours of real time. It was a tight window, yet it remained sufficient, since it gave them enough breathing room to finish resting, top off their cores, and execute a decisive joint strike against the Light Guardian before the prison gave way.
Furthermore, hunting the final guardian first could offer a massive compounding reward.
Defeating the Light Dragons would put the seventh elemental cores into Ren’s hands. If he returned to this place holding all seven elements, the mana-system agony of waking Mooshito and risking further crystallization would actually be worth the price.
They could construct a comprehensive, seven-point seal tuned to the entire spectrum of magic, leaving zero blind spots for Selthia to exploit in the future.
Better yet, there was that compounding reward chance... Getting a way to avoid the seven-point strain entirely.
If the Vanguard moved fast enough to claim not just one, but both Light Dragons across the two halves of the world, they could deny Selthia the final element altogether. If they stripped the Witch of both the rings and the cores, the corruption would have no new frequency to broadcast into the underground grid. In that scenario, a six-point array blocking her stolen Shadow Core would be more than enough to render the prisoner completely helpless at getting stronger.
The energy gap would be sealed from both ends of the board.
Ren finished pouring his surplus ether into the dome, feeling the mana lines flare as the stone walls thickened, buying back several precious hours of lost time. He slowly pulled his right hand away from the warm metal.
The action blueprint was locked in.
Step one: enforce the mandatory 24-hours, (now only 12-hour missing), of required rest across the capital to bring every combatant back to peak output to 100% power.
Step two: launch an all-out blitz against the Light Mountains, securing the rings and denying Selthia the cores at all costs.
Only when the surface was swept clean, with all seven cores secured and his own body properly rested, would he return to this place, wake Mooshito with a promise of a huge rings banquet, and forge a stronger cage that the ancient parasite could scratch at for a very long time.
Order and discipline... Each move setting the foundation for the next.
"Keep digging for a little while longer," Ren said quietly, addressing the frantic scraping echoing from the other side of the part-legendary steel wall. "I will let you widen that tunnel just enough to make you think you have a chance, right before I take that hope away. First, though, I need to be a responsible warden and confiscate the keys your assistant will try sliding under the cell door."
The metallic dome hummed beneath his fingertips, vibrating with the cold indifference of the monster inside.
Ren turned his back on the vault and began the long walk up to the castle. The parameters of the upcoming campaign had shifted. When they marched on the Light Dragon tomorrow, simply securing their own ring would no longer cut it.
This time, he had to take everything off the table.
