Ren stood there, lost in deep thoughts, his right palm pressed flat against the warm, humming metal of the containment dome, and he finally pieced together why the prisoner was digging faster.
Listening to the rhythmic, mechanical grinding echoing through the bedrock, he compared the current pace of erosion against the baseline equations he had calculated the day before.
The discrepancy was undeniable...
The construct trapped inside was operating with a noticeable surplus of kinetic power.
When he aligned that sudden spike in output with the timeline of the surface war, only one logical explanation remained: the Shadow Core.
Selthia’s horde had failed to hold the southern mountain, and they had lost the elemental ring to Sirius and Liu, yet they had managed to salvage the dead guardian’s heart. Somehow, from miles away, that stolen core was actively feeding the beast buried beneath the capital through its ethereal net.
Ren followed the thread of that deduction all the way to its structural root.
His star-shaped prison was an exercise in targeted frequency cancellation. The five massive pillars surrounding the dome were specifically calibrated to intercept the five standard elements of the natural world: fire, water, earth, wind, and wood. By running the stolen energy of those five dragon cores in an inverted phase, the array choked the energy network and neutralized the purple dragon’s control.
That five-fold suppression was the sole reason the mechanical vessel had been stripped of its five Hydra heads and capped at the base threshold of the Diamond 1 tier.
However, the shadow element was not among those five pillars...
That dark one was entirely absent from the blocking array’s runic code. Because there was no sixth pillar humming with an inverted shadow frequency to cancel the signal, the subterranean energy grid remained wide open to that specific wavelength.
The power of the southern Shadow Core was bypassing the interference entirely. It slipped through the cracks of the blockade like water through a sieve, pouring straight into the half mechanical half meat monster to fuel its excavation drills.
"Of course," Ren murmured, his fingers tightening slightly against the vibrating steel. "The lock has a blind spot. And Selthia just shoved an elemental dragon core’s flow of energy straight through the gap."
The moment he diagnosed the flaw, the theoretical solution presented itself... And right behind that solution came a mountain of logistical problems associated with it.
Ren currently possessed the exact counterweight needed to seal the leak. Sitting inside his own shadow space was the core of the northern Dark Guardian he had slain just 12 hours ago. If he pulled that core out and integrated it into the prison’s architecture, creating a six-pointed hexagram tuned to darkness now too, he could establish a phase-cancellation for the shadow element just as he had for the other five.
The blind spot would vanish...
The external battery would be severed, and the mechanical dragon’s digging speed would plummet back to its previous crawl.
The catch was that reweaving a live containment array of this magnitude was impossible without Mooshito.
Upgrading a five-point star array into a stable six-point hexagram was not as simple as driving another pillar into the dirt. It required shifting the geometric balance of the entire cavern, recalibrating the runic interference patterns, and maintaining perfect harmonic tension across six distinct elemental frequencies simultaneously.
A human mind could not process that many moving variables at once; it required the biological supercomputer of the little mushroom’s mana-mycelium network.
And Mooshito was currently dead to the world...
The tiny symbiote had slipped into a deep hibernation immediately after they erected the prison, completely spent from the ordeal. Before curling up to sleep and many previous times already, he had made his terms for waking up crystal clear: he wanted to be elevated to the Platinum rank, and he expected a full buffet of seven elemental rings waiting for him as a reward.
