I Spread my Genes to Level Up in the Apocalypse

"Really?" Ray raised an eyebrow while looking at Isabella.

"Oh, mother, what are you talking about? I never fight," Isabella said with a mischievous smile on her face.

"Really? What about that time when you broke that kid's teeth?" Freya retorted.

"That time, the guy was too annoying; he bullied one of my classmates."

"But…"

"No buts, Freya." Ray patted her on the shoulder. "She has grown to be a strong warrior, and I am proud of her. Remember, if you face even an iota of danger, I will always be there to provide strength for you."

"Father, you are the best." Isabella hugged him with a smile on her face.

"Of course, I am the best," Ray laughed, tilting his head to the ceiling.

He never wanted to see his descendants suffer like he had, but at the same time, he didn't want them to become a waste of space—only good for show and completely incompetent.

All his children must live the best life they could and receive the best education in all of human civilization. Seeing his daughter happy made Ray feel happy too. The lovely feeling of being a father was entirely different, as if he could fight the world just for them.

"Hehe," Isabella smiled gleefully.

"You… you have been spoiling our daughter too much," Freya pouted, a hint of jealousy in her eyes.

"Come, everyone gets hugs," Ray said as he embraced both Isabella and Freya.

After a long time, they separated, a rosy hue on Freya's face.

"Eh, mother, why are you blushing?" Isabella asked, confused.

"Nothing," Freya quickly shook her head, trying to distract her. "What are the plans for our birthday girl now?"

"I… I don't have many plans for now…" Isabella looked at Ray tentatively.

"Haha," Ray chuckled, rubbing her head. "I feel like it was just yesterday that you were so young, but now you've grown so much."

"I age, unlike my father and mother," she added with a hint of complaint in her tone. "And my stepmoms."

"What? Do you have a problem with your stepmoms?" Ray asked, raising an eyebrow.

"No, but there are just too many of them," she complained.

"Of course, your father has many women, but you don't have to grow up like your father and make a harem, okay?" Ray said with a poker face.

"Then why did you have so many women?" Isabella asked, a little tentatively.

"Well…" Ray paused, and Freya, who was at the side, perked her ears up, eager to listen to the conversation. "It's because you guys give me strength. The more I have your love, the more powerful I become," he spoke honestly.

"Father, you… you…" Isabella pulled on his cheeks. Even though she was two meters tall, she had to raise her heels and extend her hand just to reach him. "It's fine if you want to make excuses; I understand that you were just too horny."

She nodded, seemingly understanding.

Freya also gave some consoling pats to Ray's shoulder, nodding her head in agreement.

Ray's brows twitched slightly. "I am really not lying," he muttered to himself, feeling quite sad and dejected over it or at least showed to be.

Even if he says the truth and only speaks the truth, they still don't believe him…

"Oh, how difficulties do I have to face?" Ray lamented jokingly.

"Anyway, little brat." Ray ruffled her silky black hair, "When are you giving me grandkids?"

"Eh, father?" she immediately felt a pink taint on her cheeks.

"You are all grown up now and I am already around thirty-eight; it is the perfect time for me to gain grandkids, isn't it?" Ray asked seriously.

"You look like you are in your prime twenty though," Isabella retorted.

"You will also stop aging after reaching your prime. I can Gene Synchronize with all my descendants and share a fraction of my power, making you guys all immortal."

"I know that already, but isn't it too fast for me to find a husband?"

"My dear little daughter, do you think that I don't know that you have already picked a boy?"

"How… How do you know?" Isabella asked, her eyes wide with surprise.

Ray just shook his head mysteriously.

"I guess I can't hide anything from my all-knowing father, can I?" She puffed her cheeks, stomping slightly on the ground, annoyed.

"Why is my little princess so angry now?" Ray tilted his head, a bit confused.

Isabella stomped her legs again, looking even more annoyed, acting like a child.

"What did I do to our little princess, Freya?" he asked her with a playful tone.

"You know too much," Freya replied with a chuckle.

"Hmm," Ray touched his chin as if contemplating, "Is knowing too much what made our little princess angry?"

"Of course! Surprises are what make moments more special, but you already know everything, so there's no fun here anymore," she replied lightly before joining Isabella.

A smile appeared in the corner of Ray's face. "Even though I can be considered experienced enough, women are so difficult to understand."

Shaking his head, the trio started to enjoy the day, doing all the fun things they used to do, even going to the amusement park, just like when she was a kid.

Although Ray himself didn't want to go, to his surprise, Isabella insisted on it, leaving him no choice. Seeing her smile made his heart feel warm.

It was nice to spend some time with his children. By the time they left the amusement park, the distant sun was already on the horizon.

"Tomorrow is your coming-of-age ceremony, so you need to sleep early, Isabella. Also, are you not going to introduce me to your boyfriend?" Ray said, using his warm hands to curl her hair.

"Father, I will show him to you tomorrow," Isabella replied without much thought. "But you might be a little disappointed."

"Alright, it doesn't matter if he isn't perfect; all that matters is for my daughter to marry a husband who loves her with all his heart, isn't it?"

"Thank you, father." Isabella's eyes lit up with appreciation.

"Hmm." Ray casually nodded his head.

Then they went back into his tall skyscraper, which had been upgraded with several more technologies.

It had grown to reach the clouds, and the top floor was just a short distance away from breaking free of Earth's gravity. Ray returned to the skyscraper with Freya while Isabella went back to the lower floors.

"What are you guys doing here?" he asked, looking at the women with smiles on their faces at the sight of him.

"Come on, our step-daughter is having a coming-of-age ceremony, so we should also prepare for her," Vanessa was the first to speak up.

"Alright, alright," Ray replied with a chuckle.

He shook his head, then they all went inside. After that, one could imagine what happened as the planning and preparations began.

In the middle of the night, Ray sat in a chair, shoulders casually slumped, holding a slip of a photo of a man in his hand.

"So this is my son-in-law, huh?" Ray muttered to himself. The man in the photo was a bit shorter at 1.86 meters, which wasn't a bad height, but compared to his daughter, who was 2 meters tall, he seemed a little small.

In the photo, he wore simple clothing and glasses, giving off a nerdy vibe.

Ray waved his hand, and another piece of paper appeared, detailing the man's background. He squinted his eyes while examining it thoughtfully.

"This man's name is Alex, huh? No father or mother, and he was bullied in high school," Ray said, looking at the paper with a thoughtful expression.

"The only reason he was even registered was because of the scholarship he got."

Touching his chin, Ray chuckled to himself, pondering the young man who would soon become part of his family.

"There shouldn't be a problem with this one; she has found a good husband," Ray nodded with a touch of appreciation. He could sense everyone in the world and already knew about the guy's circumstances, which were optimal. There was nothing shady about his background; it was all clear and straightforward.

"But the same couldn't be said about my other daughter, Trix."

Another photo materialized in front of him. Trix was his second daughter with Grace; she was a little shorter than Isabella. The boyfriend she had chosen was similar to Isabella's but, unlike Alex, he came with a much murkier background.

That kid already knew who Trix was, and he was a retired soldier who had descended from a secluded place in the mountains. Ray's brow furrowed in displeasure.

"Hmm, he dares mess with my daughter? I'll teach him a lesson soon."

Ray's eyes turned cold as cinders of flame ignited, consuming the photo in his hand.

As a father, he kept a close eye on all his daughters and his son. It was his duty to protect them until they matured enough to know the world on their own.

If anyone dared to deceive or harm them, it became his responsibility to erase that threat from existence.

He glanced up at the bright red moon glowing in the night sky and chuckled softly.

"It's the perfect time."
