Chapter 40: System Upgrade, LV2

The afternoon passed quickly...

After their time together, Akihito Inuzuka had to return to her urgent experimental projects. She had skipped work during the day, so naturally, she had to make up for it by working late into the night.

Natsuhane returned alone to the clan compound, assigning tasks at the police department to his wives who had less to do.

Then, he resumed his grand plan for the clan's revival.

Two weeks flew by...

During this period, Natsuhane was extremely busy and exhausted. On one hand, he had to care for his newly married wives; on the other, the first batch of wives from the previous year had reached their peak fertility period.

In just two weeks, Natsuhane's number of children skyrocketed from over 100 to 499!

The technique, Ninja Art: Winning Jackpot, was indeed amazing. Although all the offspring born were of A-rank or below, this didn't affect Natsuhane's strength and chakra, which had multiplied dozens, even hundreds of times!

Money to raise the children was also not a concern for Natsuhane.

After the Uchiha clan was nearly wiped out, the remaining wealth fell under Natsuhane's control. Even Sasuke had willingly donated his share to support the revival of the clan.

Moreover, some of Natsuhane's wives were wealthy business owners who brought considerable dowries when they married into the Uchiha clan. Their businesses boosted the economy within the Uchiha compound, attracting many non-Uchiha customers.

Financially, they could sustain not only the current children but even several thousand more.

Natsuhane was determined to fill the entire ninja world with Uchiha descendants! Otherwise, it would be a waste of the prolific system and his identity as a transmigrator.

However, he recently faced some troubling issues.

His body, perhaps from overexertion, wasn't as strong as before. He felt noticeably weaker and less energetic.

Where he once could go for several days and nights without issue, now even one night left him feeling exhausted. He needed sleep to fully recover.

This wouldn't be a big deal, except it wasted precious time! Time that could be spent with his wives, producing more offspring.

The Ninja Art: Winning Jackpot technique was indeed powerful, but it only worked when he was "active". There would come a day when he couldn't be as "active".

While he had considered secretly buying supplements to boost his vitality, his numerous wives and former lovers were always around. Wherever he went, he'd run into one or two of them, and they would end up in a hotel, making up for lost time.

His prowess in this area was well-known in the village. If they saw him buying supplements, it would be embarrassing.

No way could he lose face like that!

But... enduring this weakness was tough.

Pretending to be stronger than he was wasn't sustainable.

Natsuhane decided that tonight, he would buy those supplements. It didn't matter if others saw him; maintaining his health was the most important and sustainable thing.

Just then...

Ding! Uchiha clan member +1, comprehensive potential score: B. Reward: host's chakra doubled!

Ding! Congratulations host, the number of offspring has reached 500. System experience bar is full, about to level up. Stay tuned!

"???"

Ding! System successfully upgraded to level 2. Reward: one level 2 gift package.

Wow!

The gift package arrived!

He remembered that the Ninja Art: Winning Jackpot was obtained from the novice gift package.

"System! Open the gift package!"

Natsuhane couldn't wait!

Level 2 gift package opened successfully. Please choose one of the following four ninja arts. Once chosen, you will master it perfectly.

Ninja Art: Unyielding Body – After using this technique, you will have an exceptionally strong body!

Ninja Art: Perseverance – Your body will possess great endurance!

Ninja Art: Winning Jackpot (LV2) – Defy science, guaranteed to win, with a 50% chance of twins or mixed twins. Any infertility will be nullified!

Ninja Art: Heartfelt Bond – The ultimate charm technique, effective on all opposite genders, making them utterly devoted!

The use of these techniques does not consume life force, only chakra, and will not affect your corresponding organs...

"Stop!"

Natsuhane interrupted, "If it doesn't affect my organs, why do I feel so weak now?"

That's correct. You previously chose the Winning Jackpot technique, which directs chakra to your reproductive organs. It doesn't support other organs. Each ninja art protects the corresponding organs. Others require different techniques for protection.

Your weakness is due to your overall body's weakness, unrelated to the technique's quality. The Winning Jackpot technique ensures your reproductive organs are undamaged.

To avoid feeling weak, I suggest you choose the Unyielding Body technique this time: gaining an exceptionally strong body!

This technique will direct chakra to your entire body, ensuring constant renewal and no wear and tear.

"..."

After a moment of contemplation, Natsuhane decisively chose the Unyielding Body technique!

This effect was crucial!

It was exactly what he needed now.

The other two techniques weren't as essential.

The level 2 Winning Jackpot technique was tempting, promising a higher chance of twins and thus double the rewards.

He'd choose that next time he leveled up.

"System, why didn't you tell me you could level up earlier? I almost resorted to consuming tons of supplements!"

Hehe, how can you blame me for that? You never asked if the system could level up.

"Damn..."

Natsuhane was speechless.

"Fine, I'll ask directly this time. System, how many experience points are needed for the next level up?"

The experience bar for LV3 is 1000 points. From now on, each new Uchiha offspring will add 1 point.

"Got it!"
