It's the Teacher's Fault for Turning Me On

Han Do-yoon returned to the tower with the half-finished alchemy materials from Evelyn.

The Safe House wasn't a reward from this time around—it was a privilege I'd received from the future before regressing. Like the Thousand-Year Prison, it was a special boon granted by the 'tower' that transcended time.

Originally, it was just an empty space replicating the environment of Floor 1. But not anymore.

After updating my records up to Floor 5, the tower had gifted me these tools. In Gehenna, getting them would've required certification from the Heavenly Tower and a bunch of hassle, but this saved me time.

If only I had a soul grinder or a stirrer, but even if I did, I couldn't use them properly right now anyway.

Han Do-yoon laid out the materials he'd brought on the workbench from outside. He'd bought the workbench with money. It was just a large table.

It's nice not having to worry about prying eyes.

Sorry to my teacher, but in the eyes of Han Do-yoon, who'd even made a pseudo-Elixir, Evelyn's process had a bunch of minor issues.

If I tweak the existing recipe just a bit... First, start with the time-consuming parts.

He put red grape wine in the cauldron and started boiling it. Once it was bubbling vigorously, he added the pre-ground mushrooms and stirred... How long had it been since he'd stirred by hand? He missed the artificial spirits that handled the repetitive labor.

To shorten the process time, maybe drawing a synthesis circle would be better?

He began drawing a synthesis circle on the dirt floor... Combining materials with a synthesis circle was inefficient for creating something. The downside was that materials got overconsumed in the reaction during combination. In exchange, you got fast combination time.

...But Han Do-yoon could reduce material overconsumption with the Thousand-Year Prison.

The basis of alchemy was equivalent exchange. He could cover the energy generated during combination not with material depletion, but with infinite 'mana'.

He placed the halted process materials on the completed circular synthesis circle on the floor and placed his hand on them. The mana circle above his head spun and resonated with the synthesis circle, leaving only pale white moss after unnecessary components were removed.

Growth-type tools? Perfect. No need to swap them out one by one.

The higher the level of an artist, the pickier they were about their equipment. Alchemists were the same. They started with clay pots but eventually used high-end tools made from mithril or orichalcum.

That was why he'd stolen Karia Redheart's unfertilized egg. It absolutely wasn't an excuse to peep on her laying.

The furnace made from a red dragon's unfertilized egg was a game-changer. Wonder when I can make another one?

He measured the weight with the scale... ground it with the mortar and pestle. Added it to the thick mushroom porridge boiling in the cauldron, mixed, and transferred to the distiller. He evaporated the moisture over low heat, extracting only the essentials, then put it in the magic catalyst reactor to boost mana content.

He repeated the process. It was time-consuming work for a person to do manually.

Looks decent.

Higher synthesis circle efficiency naturally led to better 'masterpiece' results. It still wasn't perfect, though.

No elemental fusion, soul combination, or chain reaction effects? Well, can't be helped since it's made from below Floor 10 materials.

By the time he'd used up all the materials he'd brought, the sun was setting. He headed back to Summer's Grand Triangle.

Evelyn furrowed her brows when she saw what Han Do-yoon had brought.

"This is..."

The best possible masterpiece from the given materials, no more, no less.

This isn't the level of a newbie alchemist who's just grasped the basics.

Anyone who could gauge the level would naturally suspect.

...Has he already graduated from the Heavenly Tower in practice?

She quickly dismissed the suspicion.

He'd been a total rookie without a mana circle, and she'd been the one to open that path for him.

Or is he that rumored genius?

Evelyn had been called a genius too. It had been 15 years since she'd come to the Tower World as a child... Even the top experts couldn't do this. Those called geniuses used to think inwardly, I could do that too! out of jealousy, but now she was just stunned.

I couldn't make it better than this myself.

Maybe someone else made it? She eyed her disciple with that suspicion, but his bright, honest gaze looked to her just like a disciple seeking praise from his teacher.

"Why the long face? Is there a problem?"

"No... I was worried, but you did better than expected... To be honest, it bothers me that you modified my recipe, but you did well."

"After thinking it through, swapping the process steps around seemed better."

"Cheeky... But you did good. Looks like there was an error in my calculations."

"It's all thanks to Teacher's great instruction."

Evelyn wasn't an idiot. Even in her aroused state, demanding a man's fluids periodically due to losing her mana circle, she was an alchemist with vast experience and knowledge.

Probably...

So she could guess.

The identity of the man who'd suddenly appeared one day, claiming to be her disciple.

No way he could be this good at alchemy without a mana circle. And updating records like this? It has to be... Yeah, in the Tower World, it's theoretically possible, but...

Groundless conviction. But if he wouldn't reveal the truth himself, Evelyn decided not to pry.

If what her disciple wanted was to become her disciple once more, she'd fulfill her duty as a teacher.

"...You did very well. You could say you're my disciple anywhere without shame."

Evelyn stroked his head despite their height difference. He hadn't ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠done it for this, but it didn't feel bad, so he stayed still.

No, it feels good.

Then Evelyn's chest brushed against him... His thing sprang up, unintentionally lifting her skirt.

"You... even now...!"

"It's Teacher's fault. You turn me on."

He grabbed her stroking hand and guided it to his lower parts.

"Praise me here."

Her shocked expression bit her lip tight.

Then she knelt and pulled down his pants.

"This is the last time... I need mana anyway!"

A warm, wet tongue slurped over the glans.

I put out the urgent fire in the workshop and went to find Isana. I was curious if she was doing well.

Haven't seen her face in a ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠while.

I'd made her a strength supplement using scraps from Evelyn's workshop for her sake.

Here, physical abilities grow endlessly regardless of gender, but this should still make a difference.

Gehenna's outskirts, far from the bustling streets, on a hilltop shack. Even in the Tower World, steep hills like a slum were avoided by residents. It ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠was within city limits, but practically no different from a wild mountain outside.

Relentlessly overgrown plants and bushes, embedded rocks, beast tracks—it was like suddenly encountering a military unit mid-commute.

This is the place...

Where the hill turned into a mountain.

In front of the intact-looking shack, I sensed a presence that seemed to be Isana from afar.

I had no intention of sneaking, but she looked focused, so I quieted my footsteps.

Light flashed each time her sword arced. She gripped a wooden sword, but the energy wasn't ordinary.

She sliced falling leaves, followed by double strikes hard to block with current reflexes. Something like sword aura extended, gouging the ground...

Han Do-yoon felt something eerie.

That sword aura... Not something a woman who's been here less than a month could have.

Unless she'd 'returned' like me.

But Isana was dead. No way she'd returned.

She'd drunk the poisoned Elixir right in front of me, and I'd stabbed her helpless heart with a dagger. The last time she'd turned back, her bloodshot eyes met mine as her breath stopped.

If not that...

I recalled the 'sword' I'd given her.

Nothing else connects... That sword from the future is affecting Isana?

It wasn't just her swordsmanship that had improved; her icy gaze turned to me. My heart seemed to stop for a moment...

But then she approached with warm eyes and spoke.

"Why are you peeping like a pervert? Say something if you're here."

"Walking was hard."

"You hurt somewhere?"

"Seeing you all sweaty... hard to hold back."

Isana laughed like a loose woman and swept back her sweat-damp hair.

"Falling for me now?"

"Who knows, maybe I've been smitten since we first met."

Her frank reply embarrassed her, and she looked away.

Han Do-yoon strode forward. Reading the mood, Isana stepped back once, then charged...

Her physical abilities already seemed to surpass mine. In a blink, she was in my arms.

Her legs wrapped my waist, hands gripped my face.

"Mmm... smack, missed you. slurp... Heh... Why dodge?"

"Feels like I can't beat you anymore."

"Hehe, wanna test that?"

"N-no...♡"

She puffed her cheeks, knowing I was imitating her.

But deep down, it boiled her lust; she roughly undid my belt. Her sweat-soaked training pants slid down, her moon-pale thighs pressing close.

No foreplay, not even that wet. In the few days apart, she'd been lonely; she forced my pants off and slammed her hips like a rutting rabbit.

"Ahht...!"

"Haa... This is it... Nng! Yes! Hnnght!"

"How long's it been that you're this pent up already?"

"Your... your fault! You make me... haaht... nng! Eut♡"

"Aah..."

"What... why's your moan so sexy?"

As Isana mounted and shook her hips, it felt like rape. To make matters worse, she stripped off her sports bra, smothering my face with her huge breasts.

The scent of flesh, sweat, and Isana's unique milky aroma filled my nose, muddling my head.

I reached out and grabbed her ass.

Satisfied, fluids gushed from her lower parts. Love juices flowed, soaking our crotches, adding wet smack smack sounds to the motions.

"Ugh... haaang!... Hic♡ G-good... Missed you... Mmm, sluuuurp."

Smack! Smack!

Climax built fast. Her walls clamped from all sides, squelch squelch, her womb sucking the glans.

Isana came first; her contracting insides and twitching hips spasmed back and forth.

Needing something to hold in uncontrollable orgasm, she hugged my head to her chest, bucking wildly with ohhh goook, ooook.

Each time, thick semen spurted gloop gloop into her womb.

Had Isana learned pregnancy was hard here? Or had she given up everything for breeding creampies?

I suspected the latter.

If she learned what I'd do in the future, maybe only that would let her forgive me.

"Hek, hek, heeeek... O-one more..."
