Chapter 356: Upgrades & Hybrid Lock

Firlia washed with the minimum water from the basin, a clean cloth, enough to take the worst of the evidence off her thighs.

She dressed, checked the shelf one last time out of pure reflex, and lay down on the edge of the platform opposite Thora.

Within minutes, her breathing evened.

The logistics officer who had finally put her own name in the column slept like someone who had spent the night being thoroughly counted.

Kane didn’t sleep.

Risking a full sleep on this stone felt like an invitation he didn’t want to answer.

The ridge still breathed wrong.

The Hydra still existed in the deep.

The previous Elder had walked into a pit and not walked out.

He sat with his back to the wall near the hearth, Mjoldr across his knees, and let the household’s quiet settle around him while his mind ran the same loop the lower-tier fighters had handed him.

Root-Binder.

Forest stone.

Door shut from the inside.

Never came out.

Had the corruption started here and moved outward to the belt and Sylvander’s gate?

Or had the stone been a carrier, something already tainted that found the island’s closed pits and taught them to open?

Either way, the arithmetic was the same.

More turned. More taps. Less time.

He opened the system with a thought.

"Hey, system."

[Host.]

The window hung at the edge of his vision, clean and unsympathetic in the low light.

"How many days until the devils arrive?"

[Arrival of the Devils: 46 days, 22 hours, 31 minutes.]

[Countdown synchronized to primary layer rupture estimate.]

[Secondary local events (Island taint, belt probes, Hydra agitation) are not included in the global timer.]

[Recommendation: Treat local acceleration as independent risk.]

Forty-six days.

The number had shed more margin since Berakamon.

He flexed his left hand once, felt the cleared joint answer, and kept his voice low enough that it would not travel past the waterfall’s cover.

"Is there a way to upgrade my body?" he muttered.

[Body Modification Pathway: Available.]

[Current Host Status — Summary]

[Physical Integrity: 94%]

[Rib complex: Stabilized]

[Forearm/shoulder: Cleared]

[Residual Rage backlash: Negligible]

[Controlled Berserker Output: Cap tested at 100% (arena).

[Sustainable continuous use recommended ≤70% without recovery window]

[Empress’s Mark: Active — Compulsion resistance elevated]

[Shared Bed Recovery: Available when conditions met]

[Fragment Resonance (contained): Detected — Passive leakage negligible under ward]

[New Flag: Local Taint Gradient — Elevated toward central ridge]

[New Flag: Divine-Adjacent Signature (Hydra) — Domain-bound]

Kane scrolled.

"Body modification again. I will not end up like one of those Giants, right?"

[Clarification: Body Modification Pathway doesn’t apply external taint.]

[Pathway options:

[1. Densification Reinforcement — Improved resistance to blunt trauma and partial resistance to low-grade essence corrosion. Risk: minor reduction in fine motor speed.]

[2. Recovery Acceleration — Shortens post-Rage and post-trauma windows. Risk: increased caloric demand; Host must feed adequately.]

[3. Sensory Edge — Marginal improvement to threat-detection under corrupted atmospheres. Risk: sensory overload in high-taint zones if untrained.]

[4. Hybrid Lock — Rejects uncontrolled mutation signatures. Strongly recommended given current environment. Cost: higher.]

[Note: None of the above convert Host physiology into Giant-scale or turned-state morphology. Turned states observed on this island are external essence overwrite, not elective modification.]

"Hybrid Lock," Kane said.

"Explain the cost."

[Cost: Significant stored mana / Accumulated combat yield.]

[Effect: Passive rejection of low-to-mid grade essence overwrite attempts. Does not grant immunity to high-grade or divine-adjacent forced entry. Does not remove existing external marks (Empress’s Mark remains).]

[Synergy: Compatible with Controlled Berserker Output and Empress’s Mark resistance profile.]

[Warning: Hybrid Lock will not protect allies. Party members remain vulnerable unless separately equipped or warded.]

He thought of Firlia asleep with the permanent column finally written.

Of Thora’s ribs. Of Kessa’s nose coming back in the mist. Of Griselda’s wings fighting wrong air over the cut. Of Sira on a distant wall.

"Can I extend any protection to the household?"

[Negative. Body Modification is Host-bound.]

[Alternative: Containment protocols and tactical exclusion from high-gradient zones.]

[Fragment in Host possession remains a diagnostic asset and a resonance risk if unsealed near active taps.]

Kane exhaled through his nose.

"Analyze the forest stone scenario. Berakamon had refined essence and a Supreme Devil projection. Same hand or parallel operations?"

[Working assessment: High probability of distributed ’tap’ network under single doctrinal method.]

[Patient opening of sealed sites. Local carriers (stones/charms). Secondary weaponization of domain familiars where available (Hydra agitation logged as reactive, not necessarily controlled).]

[Island may be an early or parallel node, not necessarily the origin.]

[Origin determination: Insufficient data. Recommend comparison of contained fragment against any island sample under controlled conditions only.]

[If island primary pit is still active, approach without Hybrid Lock and without high-output Rage reserve is classified: Unwise.]

"Install Hybrid Lock."

[Confirm expenditure?]

"Confirm."

[Processing...]

[Body Modification: Hybrid Lock — Applied.]

[Passive essence-overwrite rejection: Online.]

[Host baseline adjusted. Minor thermal fluctuation normal for 1–3 hours.]

[Controlled Berserker Output interaction: Stable.]

[Remaining upgrade capacity: Reduced. Further densification or recovery acceleration available after next major yield threshold.]

A low heat settled under Kane’s skin and then faded.

Just a quieter certainty that the next low-grade attempt to rewrite him would find a locked door.

He opened the wider board.

"Full threat picture. Local plus global."

[Local — Giant Island]

[Active taint: Confirmed]

[Global]

[Devil arrival: 46d 22h 31m]

[Bound assets: Menual, Elven front, Berakamon (provisional under Marisa)]

[Open: Giants (in progress), remaining powers per prior Host plan]

[Unknown: Full extent of tap network; number of remaining domain familiars; whether Supreme Devil attention is fixed or opportunistic]

Kane rubbed his eyes with his thumb and forefinger.

"If I sleep for two hours, probability of local incident."

[Insufficient data for precise probability.]

[Environmental indicators: No immediate approach signatures on lower tier.]

[Recommendation: Split rest. Host remains suboptimal if continuous wakefulness exceeds another full cycle before ridge commitment.]

[Shared Bed Recovery available; conditions partially met (multiple bound partners present). Effect reduced if Host remains on watch posture.]

He glanced at the platform.

"Two hours," he told the system.

"Wake me if the fragment spikes, if taint gradient on this tier jumps, or if anything with a divine-adjacent signature crosses the cut. Otherwise, do not narrate."

[Acknowledged.]

[Alarms set.]

[Hybrid Lock: Stable.]

[Countdown continues: 46 days, 22 hours, 12 minutes.]

Kane closed his eyes.

Tomorrow, he would meet the elders.

And then, he would jump down the ridge himself to check the corruption.
