System upgrade, LV2

An entire afternoon was gone...

Afterward, Akimi Inuzuka had an urgent experiment to work on. Since she had skipped work during the day, she naturally had to go back and put in overtime that night.

Xia Yu returned to the Clan Compound alone and assigned Konoha Military Police Force duties to his wives who had nothing much to do.

Then he resumed his shameless grand plan to revive the clan.

In the blink of an eye, two weeks passed...

During that time, Xia Yu was worked to the bone.

First, he had to look after his newly married wives. Second, his first group of wives from the previous year began reaching the peak period for giving birth.

In just two weeks, the number of Xia Yu's children rose from over 100 to 499!

[Ninja art: Lucky Jackpot Technique] really was badass.

Although all the children born had potential ratings of A or below, that did nothing to stop Xia Yu's strength and chakra from increasing dozens, even hundreds of times over!

Xia Yu did not have to worry about the money to raise the children, either.

Almost all the assets left behind after the entire Uchiha clan was massacred were under Uchiha Xia Yu's control.

Sasuke had also unconditionally donated his share to Xia Yu, contributing to the effort to replenish their descendants.

On top of that, some of Xia Yu's wives had been business owners themselves and brought incredibly lavish dowries when they married into the Uchiha.

The shops they ran also boosted the economy within the Uchiha Clan Compound. Many people who were not Uchiha frequently came to spend money there.

Never mind the children they had now-even if they had several thousand more, their finances could support them for the time being.

That was exactly what Xia Yu planned to do.

This was only the beginning. I have to have enough children to fill the entire Shinobi World!

Otherwise, I'd be letting down the Many Children, Many Blessings System, not to mention my identity as a transmigrator.

Recently, though, a few things had been troubling him.

Perhaps he had overtaxed his body. It was not quite what it used to be.

The feeling of his body failing to keep up with his desires was unmistakable.

Before, he could keep going for several days and nights without any trouble. He was young and capable!

Now, however, a single night left him feeling somewhat tired.

He had to catch up on sleep to recover fully.

Actually, that was not such a big deal,

But it wasted time!

Wouldn't it be better to spend that sleeping time with my wives and have a few more children?

Sometimes, Xia Yu considered sneaking into a pharmacy or supplement store to buy some potent tonics to nourish his body and replenish his energy.

But she had far too many wives and former lovers.

Whichever street he walked down, he would run into one or two wives or lovers out shopping with nothing else to do. They would end up heading straight to an inn or hotel together, hitting it off immediately-and once they got together, there was no end to it.

Xia Yu's prowess in that department was famous throughout the village.

Wouldn't it be embarrassing if they saw me buying tonics to nourish my body?

I can't afford that humiliation!

Even if my teeth get knocked out, I have to swallow them myself. I can't let anyone see!

But...

Swallowing teeth really did hurt...

Putting on a brave face to look better off than he was was not advisable.

Xia Yu made up his mind. Tonight, he would definitely buy some tonics.

It did not matter if anyone saw him. Keeping his body fit was what mattered most, and what would last the longest...

[Ding! Uchiha clan members +1. This clan member's overall potential rating is B. Reward: host's chakra doubled!]

[Ding! Congratulations, host. Your number of descendants has reached exactly 500. The system's experience bar is full. An upgrade is coming. Please look forward to it!]

"???"

[Ding! System successfully upgraded to level 2. Reward: one level 2 gift pack.]

Oh!

The gift pack was here!

He remembered getting the [Lucky Jackpot Technique] from the beginner gift pack.

"System! Open the gift pack, quick!"

Xia Yu could not wait any longer!

[Level 2 gift pack successfully opened. Please choose one of the following four ninja arts. Upon selection, you will immediately gain perfect mastery.]

[Ninja art: Unyielding Technique: after using this technique, you will possess an extremely robust body!]

[Ninja art: Perseverance Technique: your constitution will possess tremendous endurance!]

[Ninja art: Lucky Jackpot Technique (LV2): disregards science and guarantees conception, with at least one child and a 50% chance of twins or boy-girl twins. Before this technique, any infertile constitution will cease to have any effect!]

[Ninja art: Hearts in Harmony Technique: the ultimate charm technique, applicable only to all members of the opposite sex. Utter devotion, until death!]

[None of the four techniques above consume life force when cast. They consume only chakra and will not affect your corresponding organs in the slightest...]

"Stop!"

Xia Yu hurriedly interrupted, "If they don't affect me, why do I feel run-down now?"

[That's right. What you chose before was the Lucky Jackpot Technique. Chakra acts on your reproductive organs! As for the other organs unrelated to them, this technique cannot cover those...]

[Each ninja art only protects its corresponding organs from damage. The others require other corresponding ninja arts to protect them.]

[You feel run-down because your body itself is run-down. It has nothing to do with quality. The Lucky Jackpot Technique guarantees that your organs suffer no wear and tear.]

[If you don't want your body to feel run-down, my suggestion is to choose the Unyielding Technique this time: gain an extremely robust body!]

[This technique can apply chakra directly to the gun emplacement and the organs responsible for keeping it working, renovating them at any time. That way, you won't need to worry about wear and tear.]

"..."

After a moment of deliberation, Xia Yu decisively chose the [Unyielding Technique]!

That effect was fucking incredible!

This was exactly what he needed most right now!

The other two were not as crucial.

The LV2 Lucky Jackpot Technique was actually pretty good, too. It amounted to a fifty-percent chance of conceiving two children at once, allowing him to receive double rewards when they were born.

I'll pick that one at the next upgrade.

"System, why didn't you tell me earlier that you could upgrade? Good thing it happened right now, or I was about to start gorging myself on supplements!"

[Heh heh heh, how is that my fault? Kid, you never asked whether the system could upgrade, did you?]

"Fuck..."

Xia Yu was speechless.

"Forget it. I can't be bothered to argue with you. I'll just ask you directly this time, all right? System, how many experience points do you need for the next upgrade?"

[The experience bar for reaching LV3 requires 1,000 points. From this moment on, each new Uchiha descendant of yours will add 1 point.]

"All right~ Got it!"
