Hardening.

Then I select the wooden boxes and open them all what it gives me:

kunai x1

healing herbs x1

kunai x1

kunai x1

healing herbs x1

shuriken x1

kunai x1

healing herbs x1

shuriken x1

healing herbs x1

'Well, it's not bad, something I would expect from a chest that is made of wood'

So let's go to the next one.

box (special) x7

'I still don't understand this chest very well but I think it gives random things.'

relaxation potion (special) x1

lucky dice (special) x1

relaxation potion (special) x1

relaxation potion (special) x1

friendship water (special) x1

friendship water (special) x1

lucky necklace (special) x1

I recognize some of them and some I don't.

'Some of this stuff should be useful but I'll look at it later, the silver chest awaits'

So I select the copper boxes.

reinforced water x10

cleaning pill (level 2) x1

chunin ring x1

I focus on where it says cleansing pill.

I almost jumped for joy.

'Finally! After so long I get something like a pill'

'Because this sounds like those pills from Chinese novels besides the ring that says chunin'

But let's not sing victory because I still think the silver box will be better.

As for the reinforced water, I will try it later.

*sigh*

'Finally I got good things this time and no longer those stupid techniques to learn'

If I'm right then that pill is the most important so far.

'I'll try it later'

Then I select the silver chest.

I have high hopes for this one.

silver case:

Card: Hardening.

More power, more toughness.

'Hardening? Isn't that skill haki users of the pirate world master?'

(PA: For those who don't know, the hardening of the black skin of the world of One Piece is not haki, haki is an invisible energy that surrounds it, so this skill card is not Busoshoku haki)

Seeing that it is a skill that goes hand in hand with haki, I immediately select it.

<Sure you want to use this card>

<yes> <no>

When I select if the card disappears and immediately I feel a strong itch on my skin.

So I immediately scratch myself.

'What the hell? Why does it itch so much?'

Then after a few moments of almost unbearable itching my skin is red.

'Hope it was worth it'

So when I want to test my skills I hear a bang coming from below.

'What's happening?'

So I quickly leave the room and head towards the first floor.

Then when I go down I find Tenten and Satsuki looking at each other.

Tenten has a gun in her hand while Satsuki does too but unlike Tenten her right arm is shrunken.

"What happened?"

Then they both turn to look at me at the same time.

Then Tenten speaks immediately.

"He's back"

Then I notice that Satsuki is gritting her teeth as he stares at me but he doesn't move because Tenten is in front of him.

Going towards me will be like turning your back on Tenten who could attack you at any time.

From his face I can see that he feels a little pain in his shoulder unlike the calm expression of the previous Satsuki.

Then I frown slightly.

'The effect of the potion must have ended; now this is a problem

Thinking about it for a moment I can only propose what the other Satsuki told me.

"Hey Satsuki, I think we should resolve this more peacefully why not use a com-"

"Hush, do you think I don't know what they're up to, but it's pointless anyway"

'Do you have memories of the other Satsuki?'

"Because?"

"I am stronger than you, do not think that because you won once you are already stronger than me, you just caught me off guard, you are still someone weak"

'Damn, that attitude of hers annoys me, if she wasn't stronger than me, I would have taught her a lesson that her parents didn't teach her'

'But I still don't understand, why she is so grumpy, much more than in the anime'

'I have to fix it somehow, fighting here will only hurt both sides and the worst will be that my house will end up destroyed'

"You know Satsuki, although skill, ingenuity and power are essential for a ninja, you are forgetting something that is as important as the previous ones"

Then she thinks for a moment.

"Luck"

I say this without giving you much time to think.

"Lucky?"

"Sometimes your life will depend on luck, so I suggest you make a small bet to see if your luck is greater than mine"

I open my hands and there are some dice in it.

Lucky Dice (Special)

'I hope you accept'

"..."

She remains thoughtful by my proposal.

"Come on, the loser accepts what the winner says"

Then I give a view to Tenten who is on the other side.

Tenten then steps closer as she draws another kunai indicating to Satsuki that she has no choice.

'I think that saying the last thing has been risking it too much but she trusted that if it is something of the system then it must be for my benefit and not the others'

So after thinking for a moment she agrees.

"Okay"

"Then let's go to the table"

She started to walk towards the kitchen.

I look around the sink where I find a wooden glass.

'This will do'

So I walk over to the table.

On the other side is Satsuki with an irritated attitude and further back is Tenten keeping the gun in her hand.

'After this I hope not to interact with her anymore'

'Let's finish this quickly, I'm sick of dealing with you girl'

"So odd or even numbers?"

"Pair"

Then I put the dice inside the glass. I shake it up and put it on the table quickly.

When I pick it up, the numbers 5 and 3 appear.

'Well, as I thought, the system is on my side'

"I won, now get out of here and I hope we get along in the future"

When I'm about to get up Satsuki pulls her fist towards the table making a loud noise.

"I'm not convinced, how do I know you didn't cheat?"

*sigh*

'It's not going to be that easy, is it?'
