The simulation continued, following the exact path Ximen Zhen had carefully set in advance.

[Konoha Year 72] Your life revolves around three things: writing, physical training, and researching ninjutsu. Even your daily married life with Tenten has gradually decreased.

Under your deliberate planning, Tenten has not become pregnant. But you both are still young, and you've stated that you're in no rush.

[Konoha Year 74] Life continues on steadily. You still have no children.

[Konoha Year 76]... Konoha Year 78]...

[Konoha Year 80] Naruto becomes the Seventh Hokage. The next generation of Konoha ninjas is set to graduate next year, and new storylines are about to unfold—yet you still have no children.

Tenten's declining mental state is increasingly visible. She's secretly visited Tsunade for a full examination, and Tsunade confirmed there's nothing wrong with her.

[Konoha Year 81] Tenten's emotional state continues to deteriorate. Eventually, she can't bear it anymore and insists on taking you to see Tsunade...

Seeing this prompt, Ximen Zhen quickly used his final simulation guidance opportunity.

His original plan had been to delay childbearing until Konoha Year 85, which he thought wouldn't be difficult—after all, in the original timeline, Tenten remained single at that age.

But now, it was clear he had underestimated the maternal instincts Tenten had developed as his wife.

After some thought, Ximen Zhen decided it was time for Tenten to become pregnant.

After all, someone as skilled as Tsunade would certainly see through any health-related deception. Besides, Ximen Zhen couldn't bear to see Tenten continue to suffer emotionally.

Next time, he thought, he'd just tell her he wanted to wait until age 35 to have children—Tenten would likely agree to that.

With that settled, the simulation continued.

[Konoha Year 81] Now 34 years old, Tenten finally becomes pregnant. She is overjoyed and deeply cherishes the child.

[Konoha Year 82] Your child is born. Out of guilt, you let Tenten choose the name—and she names her Ximen Tiantian.

Congratulations! Simulation successful!

Calculating Ximen Tiantian's bloodline talent. Please wait...

Staring at the final message, Ximen Zhen was momentarily stunned.

The child's name is still Ximen Tiantian? Could it be that Tenten truly likes that name?

Or perhaps... the child they were destined to have would always be a girl named Tiantian?

That thought unsettled him slightly.

He silently asked the system for clarification.

But this time, there was no response. The system was still focused on calculating the simulation results.

Not that he'd expected an answer—his system wasn't the kind to provide intelligent replies. At best, it gave detailed explanations of certain mechanics.

"Maybe it's just a coincidence..." Ximen Zhen muttered to himself.

Soon, the system displayed the results.

Congratulations! Simulation successful!

Ximen Tiantian has inherited and expanded upon both your and Tenten's talents. She possesses minor talent in space-time ninjutsu and has jōnin-level potential.

Stats are as follows:

Ninjutsu: 6 Taijutsu: 7 Genjutsu: 4 Wisdom: 7 Strength: 4 Speed: 7 Stamina: 5 Seals: 5

Special Talent: Intermediate Space-Time Ninjutsu Affinity

Would you like to store this simulation result and accept the bloodline talent as a reward?

Ximen Zhen stared blankly at the glowing characters, momentarily dazed. He quickly forgot all about the repeating name.

What did he just see?

His daughter... had an actual space-time ninjutsu talent!

Not like Tenten's innate affinity for using scroll-based space-time sealing techniques—this was a real aptitude for training in true space-time jutsu!

His daughter was truly remarkable!

The thought made Ximen Zhen want to leap into the simulation, scoop up his newborn daughter, and shower her with kisses.

Despite having lived two lifetimes, Ximen Zhen had never been a father—but in that moment, he suddenly understood the overwhelming emotions behind the phrases "a dragon among sons" and "a phoenix among daughters."

Compared to the bloodline talent entry, the fact that Ximen Tiantian's base stats were slightly higher than his and Tenten's seemed trivial.

This was space-time ninjutsu!

One of the most broken ninjutsu categories in the entire shinobi world.

From its first appearance, it had been game-changing. Even during the final Ōtsutsuki battles, it remained a critical ability.

Without it, even someone as powerful as Sage Naruto could be thrown into a pocket dimension and starve to death.

Of course, Ximen Zhen was well aware that his daughter's aptitude likely didn't compare to someone like Minato Namikaze—but the important part was that there was hope!

Tenten's talent had originally only extended to the proficient use of space-time sealing scrolls. That was powerful and highly practical in battle, but it wasn't a direct combat talent.

But once Ximen Zhen had copied Tenten's talent and combined it through their child, it seemed to "evolve"—like a Mendelian pea gene suddenly becoming dominant.

This meant that if he repeated the process—strategically pairing and simulating—he might be able to push this space-time talent to its absolute limit!

At that point, Ximen Zhen could become a flash-style ninja—the kind that could dominate Konoha and even the entire shinobi world.

No... wait.

As he reviewed Tenten's genetic contribution, Ximen Zhen realized he'd overlooked something.

Tenten's own talent also needed to grow, or else further evolution of this space-time trait would become impossible.

It looked like he'd have to deepen his relationship with Tenten in real life, too... Not that Ximen Zhen minded.

If he had to choose any girl in the shinobi world as his wife, Tenten would still be his first choice.

The reason? Familiarity.

She was so familiar, so dependable—it put his heart at ease.

Still, if he committed to Tenten now, would it be immoral to simulate children with other girls later? ...Well, it's just a simulation anyway.

Ximen Zhen took a deep breath and chose to replace the previous simulation result.

He wasn't worried about losing the novel drafts or ninja tool blueprints from before—he had already set them to automatically carry over into future simulations.

Ding! Bloodline talent is being transferred... Estimated duration: 10 minutes.

The familiar sensation returned. This time, Ximen Zhen sat cross-legged and tried to suppress the ticklish and tingling feeling.

But this time, the sensation was particularly intense. It felt as if his body were disappearing, as if his consciousness were falling into a black hole.

To any outsider, Ximen Zhen, who had just sat upright, suddenly slumped over, trembling uncontrollably.

It was the dead of night. Normally, he could behave however he liked in his own home.

But unknown to him, a pair of eyes had been watching his every move from the shadows.

The moment she sensed something was wrong, she flickered through the window in an instant.

A pair of pale hands gently pressed against Ximen Zhen's neck. At the same time, a system prompt appeared before his eyes:

Currently in contact with high-potential kunoichi: Yugao Uzuki.

Time remaining until full pheromone collection: 59 minutes…
