Chapter 53: F-Rank Dungeon

Morning light filtered through the half-drawn blinds of the bedroom, casting pale gold stripes across the floorboards. Kael sat in the low armchair beside the crib, his elbows resting on his knees as he watched the slow, steady rise and fall of Noah’s chest.

On the small table beside him, his phone vibrated.

Kael snatched it up before the buzzing against the wood could wake his son. The screen lit up with a message from Marcus Vale, the senior instructor at the Hunter Association.

Marcus: How are you feeling? You were supposed to attend the beginner training session yesterday, but you didn’t show up.

Kael dragged a hand down his face, feeling the rough stubble along his jaw and the lingering weight of a restless night. He had meant to message the Association the previous morning, right before Noah’s fever had spiked and driven every other thought from his mind.

Kael: I’m sorry I didn’t reach out sooner, Instructor. My son fell ill yesterday, and we had to take him to the clinic. I couldn’t leave him to attend training.

Three dots appeared on the screen almost immediately.

Marcus: Is the boy all right?

Kael: He’s doing much better today. His fever broke during the night. We’re still keeping a close eye on him, but the doctor said he’s over the worst of it.

Marcus: Good. Don’t worry about missing one session. Family comes first, and I have no use for a recruit who would leave a sick child behind just to swing a practice sword.

Some of the knot between Kael’s shoulder blades loosened. After Marcus had personally overseen his evaluation—and witnessed the bizarre reaction of the Association’s appraisal stone—Kael had half-expected the gruff veteran to view an unexcused absence as a lack of discipline.

Kael: Thank you for understanding. When can I make up for the session I missed?

Instead of another text, the screen shifted to an incoming call.

Kael rose quietly from the chair, stepped toward the window so his voice wouldn’t carry into the crib, and answered. "Good morning, Instructor."

"Good morning, Kael," Marcus’s gravelly voice came through the speaker. "You sound considerably more awake than the last time I saw you. How are the ribs?"

Kael pressed his free hand lightly against his sternum. The deep, bruising ache from his previous ordeal had faded to a dull tightness whenever he drew a full breath. "Mostly healed. My chest doesn’t ache much anymore, and I can move around without stiffness. I’ve been holding off on any heavy exertion, though."

"Smart. Keep it that way until the clinic clears you completely," Marcus said. "I don’t want you rushing back onto the training floor only to end up occupying a bed in the medical wing five minutes later."

Kael smiled faintly. "I’ll do my best to avoid that."

"See that you do. I have enough paperwork without having to verify whether my recruits are still breathing."

"I’ll try not to add to your stack, sir."

"That’s what they all say," Marcus muttered, though there was no real bite in his tone. He paused for a beat, the faint rustle of papers audible on his end of the line. "As for yesterday’s session, the cohort mostly covered baseline conditioning, introductory weapon handling, and standard Association regulations prior to dungeon entry. It’s foundational material—nothing we can’t catch you up on in an afternoon."

"That’s a relief," Kael admitted.

"Tomorrow, however, we’re moving out of the classroom."

Kael straightened slightly, his gaze drifting toward the street below. "Where to?"

"An active gate perimeter," Marcus said. Before Kael could speak, the instructor continued briskly. "Don’t get ahead of yourself. This isn’t a raid, and I have zero intention of marching green recruits through an open portal to fight monsters."

Marcus explained that the Association required every new wave of initiates to observe a live containment zone under strict supervision. Classroom lectures could explain mana fluctuations and monster classifications on a whiteboard, but they couldn’t replicate the atmosphere of an actual spatial tear.

"Half the rookies who walk through our doors think becoming a hunter means strapping on a blade and charging blindly at the nearest beast," Marcus said, his voice turning serious. "The other half assume E-rank and D-rank gates are harmless errands because the monsters inside aren’t high-tier threats. Both mindsets put people in coffins."

Kael listened silently, his fingers tightening slightly around the phone.

"Tomorrow is about seeing the machinery that keeps hunters alive," Marcus continued. "You’ll observe perimeter security, mana-reading verification, equipment inspections, and how the logistics and support crews operate before a strike team ever steps across the threshold. Depending on the timing, you’ll also see an active team cycle out from a clear."

"Observation only," Kael said.

"Strictly observation. Your official rank is still entry-level, and regardless of whatever anomaly happened with that appraisal stone, raw potential doesn’t equal field experience. I don’t send unprepared people into gates."

Kael thought back to the hairline fracture that had spiderwebbed across the testing crystal and the strange, heavy pulse that had echoed in his chest. It was a mystery he still needed to unravel, preferably far away from prying eyes.

"I understand," Kael said. "What time should I report?"

"Association main entrance at eight hundred hours sharp. We’re taking a transport bus together. Wear durable clothes, sturdy boots, and bring your provisional ID. I’ll brief the group on site protocols before we roll out."

"I’ll be there."

"Good. And Kael?"

"Yes, sir?"

"Check on your boy in the morning before you walk out the door," Marcus said, his tone softening just a fraction. "If his fever comes back or your family needs you at home, call me. Gates aren’t going anywhere. The exercise can wait."

Kael looked back toward the crib, where Noah was tucked beneath a soft cotton blanket, one tiny fist curled near his cheek.

"Thank you, Instructor. Really."

"Just get some rest—and don’t try to make up for lost time by doing two hundred push-ups in your living room tonight."

"I won’t."

"That’s what they all say," Marcus repeated dryly, and ended the call.

Kael lowered the phone and shook his head with a quiet huff of amusement. For a man who looked like he chewed iron for breakfast, Marcus Vale was surprisingly difficult to dislike.

Slipping his phone into his pocket, Kael walked back to the crib.

Noah was beginning to stir. His eyelashes fluttered, and he let out a soft, squeaky sigh as he stretched his short arms overhead. Kael leaned over the railing, the tension of the morning melting away into a warm smile.

"Good morning, little man," Kael murmured, gently laying the back of his knuckles against Noah’s forehead.

The skin was warm, normal and soft—nothing like the frightening, radiated heat that had greeted them twenty-four hours ago.

Noah blinked up at him with wide, dark eyes and made a quiet burbling sound.

"Much better than yesterday, huh?" Kael whispered, picking up the digital thermometer from the changing table to double-check, just as the clinic nurse had instructed. The quiet beep confirmed a normal reading.

Even with the proof in his hand, Kael took another moment simply to watch his son breathe. The previous day had rattled him far deeper than he had let on to Sera. Watching someone so small and fragile cry in distress, unable to tell them what hurt, had carved a hollow, helpless ache straight through his chest. All the strength in the world meant nothing when the enemy was a fever you couldn’t hit. He had spent half the night sitting in the dark, listening to every hitch and sigh from the crib.

A familiar, translucent blue pane materialized in the corner of his vision, chiming with a sound only he could hear.

[Family Man System]

[Family Care Assessment Updated.]

[Your attentive care and vigilance during your child’s illness have been recognized.]

[Special Family Milestone: Supporting Your Child Through Recovery.]

[Reward Granted: $3,000.]

[Additional Effect: ’Family Guardian’ remains active. Continue prioritizing your family’s well-being to maintain system synergy.]

Kael read the glowing text once, then dismissed it with a blink.

Three thousand dollars was nothing to scoff at—it would go straight into their savings buffer and cover Noah’s clinic bills twenty times over—but the reward felt entirely secondary. He hadn’t sat beside the crib in the dead of night hoping for a system payout. He had sat there because the boy in the crib was his whole world.

He reached down, letting Noah’s miniature fingers curl instinctively around his thumb.

"Keep getting stronger, okay?" Kael said softly. "Your mother and I could really use a boring day."

Noah blew a tiny bubble of spit and kicked his legs under the blanket.

"I’ll take that as a binding promise."

"Who are you making shady deals with this early in the morning?"

Kael turned toward the doorway. Sera stood leaning against the doorframe, dressed in a soft knit loungewear set, her hair tousled around her shoulders and the faint imprint of a pillow crease fading from her cheek.

"Our son," Kael replied, keeping his voice low. "We’re renegotiating his nighttime schedule."

Sera padded across the room in her socks and came to stand beside him, resting her chin lightly on Kael’s shoulder as she peered down into the crib. "And what were his terms?"

"He agreed to let his parents sleep for at least five consecutive hours tonight."

Sera arched an eyebrow, giving him a sidelong look. "Did you get that in writing?"

"No. We settled on a gentleman’s verbal agreement."

"Then you’ve been swindled," she said, a smile tugging at the corner of her mouth. "Look at that face. He has zero intention of honoring a contract."

Kael chuckled softly, wrapping an arm around her waist and drawing her close. Sera leaned into his side, reaching down to gently stroke Noah’s soft cheek.

"His skin feels cool," she whispered, the relief in her voice unmistakable. "How was his temperature?"

"Completely normal. I checked it right before you walked in, and I gave him his morning drops." Kael kissed the side of her head. "Did you manage to get a few more hours of sleep?"

"A few. Having you take the early morning watch helped." She looked up at him, her expression softening as she studied the faint shadows beneath his eyes. "Are you still worried?"

Kael didn’t bother putting up a front. "A little," he admitted quietly. "Logically, I know the fever broke and he’s on the mend. It’s just hard to shake the image of how miserable he was yesterday."

Sera slipped her fingers between his, her palm warm against his skin. "Then we take today as slow as we need to," she said gently. "No big errands, no rushing around. Just the three of us."

Kael squeezed her hand. "That sounds like the best plan I’ve heard all week."

By late morning, the apartment felt brighter. Noah had taken a full bottle without fussing and spent twenty minutes happily batting at the soft plush stars dangling above his play mat.

Once he settled into a contented doze, Sera stood near the living room window, holding a warm mug of tea between both hands as she looked out at the street below.

"The breeze looks really mild today," she murmured. "All the sun is out."

Kael walked over from the kitchen counter, drying his hands on a dish towel. "It’s supposed to stay clear until evening."

Sera glanced back at him. "What do you think about taking him down to the neighborhood park for twenty or thirty minutes? The nurse said fresh air would be fine once his fever stayed down, as long as we keep him out of the wind."

Kael considered it, looking over at Noah. "A short walk wouldn’t hurt either of us, honestly. We’ve been cooped up in these four walls stressing since yesterday morning. If he starts looking tired or fussy, we can be back upstairs in five minutes."

"Deal," Sera said, her posture visibly brightening.

Getting out the door took half the time it had during their first few outings as parents. In the beginning, Kael had treated a trip down the block like a military deployment. Now, he moved efficiently, tucking two spare diapers, a travel pack of wipes, a clean burp cloth, a light muslin blanket, and a prepared bottle into the side compartments of the diaper bag.

Sera paused while buttoning her light cardigan, watching him zip the bag shut with a raised brow. "Wait. That’s it?"

Kael looked up, blinking. "What did I forget?"

"Nothing. I’m just in shock," she teased, stepping closer. "The first time we took Noah out, you packed four spare onesies, two winter blankets, a portable changing station, and enough diapers to supply a maternity ward."

"I was accounting for contingencies," Kael said defensively, though his lips twitched.

"We were going to the pharmacy across the street, Kael."

"And did we run out of supplies?"

"We were gone for thirty-five minutes."

Kael slung the strap over his shoulder with quiet dignity. "You can’t argue with a hundred-percent success rate."

Sera laughed, shaking her head as she reached for the stroller handle. "Come on, Mr. Tactical. Let’s go get our son some sunshine before you decide we need emergency rations."
