"Ronald, I won't grow three heads or six eyes, right?"

"I've read those popular science fantasy novels recently! Those Frankenstein stories, they can even attach a person's head onto a table leg!"

Having decided to modify Nicole's genes, Ronald began choosing the most suitable ones from his existing gene library after taking a bit of her blood.

During this time.

The investigator girl couldn't stay idle, her curious gaze circled around and rested on Ronald;

"With your kind of spell, can you do such a thing?"

Ronald gave her a blank stare:

"Nicole, get this straight, we're both mystical Casters!"

"Magic and science fiction are not the same system."

Ronald very realistically denied it.

However, Nicole clearly had her own opinions on this point, so while Ronald denied it, the investigator girl stubbornly said:

"You never know!"

"I've seen people who've modified their bodies all over the place, I heard they even need to eat a live eel regularly for energy. Those guys look exactly like they do in the novels."

"Sometimes I even think—maybe the original spells we study are the world's future."

When Nicole said these things, her eyes sparkled, her anticipation for the future was visible to the naked eye.

And Ronald is an honest person.

So for a moment, he couldn't even refute Nicole's words.

He knew very well that besides some religious myths, novels, and travel notes, this world's originals also included a large volume of academic journals. The "maybe it's the future" that Nicole mentioned actually had a significant probability of happening in this world.

"You'll have to see that yourself in the future to know."

"..."

As they continued their casual chatting, Ronald's carefully prepared gene sequence had already taken shape. Before adding various enhancement indicators, Ronald turned to Nicole and asked:

"Let me confirm one thing."

"Undergoing this modification, your life will definitely be much longer than ordinary people's. So, Nicole, do you have any thoughts on how long you want to live?"

Hearing this, Nicole got excited and even asked Ronald back:

"How long I want to live?"

"Ronald, are you saying I can just pick any number?"

"..."

Ronald fell silent.

Because Nicole could indeed pick any number.

Since acquiring "The Origin of Species," one of the enemies Ronald defeated was a species created by the "Organic Encyclopedia," which also had infinite life.

And acquiring this genetic ability...

To be honest, although Ronald hadn't used it on himself, modifying lifespan now is just a matter of minor operation change.

Casually increasing Nicole's lifespan by several hundred years or directly setting it to infinite, the difficulty difference is about the same as making a cucumber salad versus a tomato salad.

"..."

"Ronald, did I really get it right?"

With her lively mind and knowing Ronald's personality, Nicole asked again, purposely lowering her voice to prevent the other investigators nearby from hearing their conversation:

"Can you make me have infinite life?"

"..."

"Indeed I can turn you into an immortal species, but a long life isn't necessarily a good thing." Ronald chose to be honest in the end, yet he also warned the girl in front of him, "But I hope you'll consider it carefully."

"..."

Just like how Ronald once did.

Having received this clear information, Nicole inevitably fell into contemplation.

At this moment, what came to the investigator girl's mind were the Casters she had once seen pursuing immortality, even from her perspective as an investigator, their madness was uniquely exaggerated.

Nicole seriously recalled everything she had seen and heard, and carefully considered what immortality meant to her personally.

In the end, she still chose to shake her head:

"Ronald, not necessary."

"Having a healthy body is what satisfies me."

Making such a decision, Nicole was immediately relieved, as this choice was also difficult for her.

However, just a few seconds after making this decision, Nicole suddenly remembered something as if awakening from a dream:

"Oh right, Ronald!"

"If your ability can heal my injuries, then it's best not to restore my eyesight."

"Huh?"

Ronald displayed a slightly surprised expression upon hearing this:

"You mean—you'd like to keep one eye blind?"

Nicole straightforwardly nodded in response:

"That's right, I wish for this eye to remain blind."

Ronald looked quite puzzled, as no one had a reason to want one eye to lose sight:

"I don't think this is a wise choice."

"Or... do you have any other difficulties or reasons?"

"Actually, it's quite intriguing." Given it concerned the safety of her own body, Nicole naturally explained everything without reservation, "Before coming here, this eye wasn't blind. It was after we entered this underground world that we encountered some dangerous plants..."

Nicole slowly narrated her story, and the experiences this investigator team had underground were quite legendary indeed.

It was just two months ago.

When the investigators first arrived in this underground world, they encountered a dangerous plant in a cave.

To save her companions at the time, Nicole got trapped by that dangerous plant, then she fell under the branches. During this process, her eye was directly pierced by that dangerous plant.

And so, something very remarkable happened.

Falling on the tree and having her eye pierced seemed to activate some kind of ritual in Nicole's spell system that had never been discovered.

After a long enough time passed.

Nicole realized a new comprehension of her runic spell system, and the power she possessed was vastly different from before. Previously, she could apply short terms through the combination of runes, and now, given enough time, she could even spell out complete sentences entirely from runes!

This new casting ability possessed unimaginably mysterious powers.

So even though one eye would lose sight, Nicole weighed the pros and cons and felt the trade-off was acceptable.

"..."

Nicole's story concluded slowly.

Sitting in front of him, Ronald had fully constructed the desired gene module after this conversation.

He gave the girl in front of him a look indicating the commencement was about to begin.

The spell composed of the life force and Magic Power mixed in Ronald's hand had also manifested its spell glow.

"Alright, we'll start now."
