Longevity Evolution Gene Lv.2

'Hmm, but as I thought..., even discovering something mysterious doesn't give that dramatic ping where scientific power visibly shoots up or anything. It just gets applied automatically in ways you can't see, right?'

Maybe because the game had become reality, it was definitely different from the game. In Project Zombie World, the game version, there were no aircraft or armored units as objects, so you couldn't use them at all. But in the realized Project Zombie World on Tower Floor 1, me and my subordinates were making great use of military drones, operating armored vehicles and tanks too. And just recently, we'd rescued a retired helicopter pilot and mechanic—one each—and were buzzing with anticipation about whether we could operate the military helicopters that had only been scrap until now.

'Yeah, definitely. In Project Zombie World, shooting zombies should've easily leveled up marksmanship and stuff, but it didn't at all. The only skills were the ones you had to buy from the point shop managed by the overall Tower system. ...So the system format is different from actual games, huh.'

In that sense, in this Tower Floor 9 civilization world, there were no visible quantified stats like scientific power, cultural power, and so on. In fact, that felt more realistic.

'Scientific tech development is more realistic too, according to Little Sis.'

Our tribal nation was focusing development in sequence: 'agriculture-pottery-writing-calendar-navigation-pastoralism-hunting-archery-wheel-mining-masonry-bronze.' Unlike games, though, there were guys already fishing from primitive rafts made of logs before fully mastering navigation or pastoralism tech, and kids from our tribe doing primitive herding. Same with archery, stoneworking, or masonry.

Before me and the women in my family said, "Let's develop this tech!" there were occasionally guys already using it primitively. Little Sis explained it like this.

"Civilization 8 mod definitely had 'tech diffusion' and 'automatic innovation.' I think stuff like you doing primitive herding while crossing Central Asia, or your tribesmen taming dogs on their own—those count as tech diffusion or automatic innovation."

"No idea what you're saying."

"...Sigh, what I mean is, bro. Tech that's already in use by other civilizations, or happens by chance, or even stuff humans naturally figure out... the tribe doesn't have to obsess over developing it as a whole; it gets picked up naturally to some degree."

"...So, you don't have to obsess ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠over scientific tech development, and it develops on its own? Then Little Sis, stop busting your ass making bronze tools lately and just fuck more with me."

"No, you idiot bro! There are automatic developments, sure, but it's different from society or the nation pushing hard! Tech developed organically by civilians versus national policy ramming through state research projects—the development speed is totally different!"

"Ah.... I see."

"And we need bronze quick to get the next evolution gene trait choice. Longevity Gene Lv.2 adds 60 years to lifespan and keeps your 20s body going 20 years longer, right? Huge perks. And it applies retroactively to kids already born... gotta develop it fast."

Little Sis's kids were already nearing their 40s. As a mom, she wanted them to live even a bit longer. Especially after her seventh kid, her third son, got killed by a barbarian stone axe during the last barbarian subjugation—she bawled her eyes out, spent almost two years like a vegetable... Me and the family really looked after her.

'We fucked a ton since she seemed to improve bit by bit during sex. She fully recovered after popping two more kids in those two years as replacements.'

It wasn't the first child death from old age, but natural death from aging was inevitable, so Little Sis wanted to delay deaths of kids and grandkids as much as possible.

"Bro, what're you thinking?"

"Huh? Nothing. Just wanna fuck you... that's it?"

"...Sigh, seriously. You're hopeless...♡ Can't resist you...♡ Wait a sec. Something's brewing about bronze. ...Ahh, if not for the knowledge seal, if we just had the concept established, we could push it through. So frustrating."

"Hey, think tomorrow—suck my dick instead. Seeing you furrow your brow all thoughtful got me hard. Take responsibility."

"No, really...♡ Just wait a bit. Sigh...♡ Slurp, slurrrp."

Little Sis dropped her thinking and sucked my dick hard. Not just mouthpussy service—she used her pussy and ass too, serving my cock's pleasure with full devotion.

Dozens of years later, Little Sis developed bronze with her subordinate priests.

'Gene: Select Longevity Gene. Okay. That makes Longevity Gene Lv.2. Now my descendants will live about 60 years longer. But we developed bronze later than expected. It's already 3780 BC. 220+ years since start.'

According to Little Sis..., if I hadn't kept fucking her and distracting, we could've done it dozens of years earlier or whatever.

'What bullshit... She was the one begging daily to cum inside and make more babies.'

Little Sis and the women in my family had each lost about five kids and grandkids to death, so they'd grown somewhat numb to descendants dying. To me, it seemed like they'd gotten used to it, or decided not to over-immerse in this game world inside the Tower.... They were ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠shocked hard the first time a kid died, but afterward, the impact lessened gradually. No more 2-3 years as vegetables—just grieving for days or weeks?

Especially Big Sis, with her tough, laid-back personality, now talked about it like no big deal.

"Fuck, hey. Park Seung-ho. You gonna manage your sons and grandsons or what? Our direct descendants—you gotta handle them! My 35th son's 22nd son died hunting. One died hunting last month too. It's all 'cause you caught that big tiger alone and bragged about the pelt—kids get hyped and go solo hunting and die. You fucking retard."

"...Ow, why hit for real. Ah..., don't hit my head. And why's it my fault? They're the ones with no skills but balls hanging out. Think tiger's for anyone...? Go with others. What's solo hunting mean?"

"You fucking retard. You went alone and bragged like hell, that's why! What? 'True warriors hunt tigers solo'? Fuck off, you fucking retard. And your sons, your grandsons—must take after your dumbass."

"Hilarious. If only Big Sis's sons and grandsons do it, maybe bad parenting. Ow, aaah, hitting head again. No, it's true. Little Sis, Fourth Sis, Second Sis, Mom's kids don't go solo tiger hunting like idiots. Heard about Second Sis's? They went 30-strong, caught three tigers. Sold byproducts, economic boost blah blah—total copy of their mom."

"Bullshit, wanna keep yapping? Wanna die?"

Big Sis hated her kids compared to Second Sis's, face twisting ugly. Muttering about organized tiger-hunting armored squads—she was seriously pissed at my comparison.

"No guns era, iron not developed yet. Bronze is ritual ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠stuff, not practical. Normal to go solo tiger hunting with stone knives? Why my fault."

"You. Went. Hunting. Alone! Bragged. Like. Hell!"

Big Sis smacked my back in rhythm. I resisted half-heartedly. I'd bragged hard—the tiger pelt and hat looked too badass, I was geeking out.

"Tell Big Sis's kids to wait—Little Sis is making bronze weapons, not just ritual. Coming soon."

"Your kids too! You stupid idiot kid! I pop 'em alone?!"

'No, shit. Honestly, don't know the name or face of my/ Big Sis's 35th son's 22nd son. Who's that? Grandsons ain't one or two. Even if Big Sis only thinks her kids, I got Mom to Little Sis. Plus harem girls popping tons.'

The women in my family had gotten pregnant yearly, steadily birthing my kids. Those kids, with great genes, got lots of women and popped many babies. Grandsons too many to remember all.

'Grandsons are tame. Great-grands and beyond? No clue.... Big Sis probably can't remember all hers either....'
