The Multiverse Conqueror

Three days past like a wind Xin use all his effort to heal Kuina and train Zoro in his free time, In his 3 days of staying here, he teaches a lot of knowledge and skill to both of them and the disciples. While casual sparring to Kuina's father Koushirou and it's time to say goodbye to them.

In his last night staying in dojo Xin cook a feast for Koushirou, Kuina, and Zoro.

He uses a lot of sea king's meat for them while Koushirou got drunk so much that he need Zoro to carry him.

The only left in the dining hall is Kuina and Xin.

Kuina asks,"Where are you going after this?"

Xin answers, "I'm going to travel back to Sabaody Archipelago to do something there and then back to east blue to continue my training"

Kuina stare him can't help but said, "Your life is full of adventure, someday I want to go out in the sea and go to my own adventure"

Xin nodded,"Someday you will"

And another awkward silent.

...…

In pass days helping Kuina recover Xin kiss him almost every morning and evening like there couple who greeting each other.

First Kuina is embarrassed to do it even if it was just a way to heal her internal injured but Xin was too patient in doing this he even make a fool out of himself to make Kuina agree for him to heal her in some conditions.

Like he needed to embrace her while passing his blood orally or let her sit on his thigh while doing it.

Everything that Kuina wishes him to do, Xin does it he even ask why need to this kind of silly thing.

Kuina only answered Xin, "It because made me feel that we become husband and wife"

(Writer: This one is to open the already in the step where husband and wife flirting)

Seeing Kuina like his doing then, he just accept his fate.

....

Suddenly Kuina said, "This morning I take a bath i notice that a strange mark form in my chest part do you know what is that Xin?"

Xin puzzle he doesn't know if that is a side effect of his god energy or blood.

System said 'That mark in his body is a proof that he was already a member of your family'

Xin dumped ' How did this happen?'

System answers,'Because you use your blood and energy to heal her your mark left to him it's not a side effect the mark only appear if the individual is willing to have it'

'Not only that the mark can give him special energy like your god energy it was defended to what kind of mark she gets'

Xin stare her and ask, "Kuina what kind of mark appears in your body?"

Kuina's face becomes red and murmur said, "It looks like a bird … maybe a fish … I don't know"

Then she stares Xin's eyes and said, "D-Do do you want to see it?"

PFFT

+10000 MOE DAMAGE

Xin thought, 'System can you identify what kind of energy he get if i know the kind of mark he has?"

System,'Yes host'

Xin stare him and shameful said, "Can i?"

Kuina stare left and right then she grab Xin's hand then she drag him to his room.

After coming to her room he close the door and lock it.

Xin surprised and said, "Why did you drag me here in your room?"

Kuina curse him, "Idiot you said you wanted to see it so i drag you here"

Xin embarrass said, "Sorry, I forgot we are in the dining hall"

Kuina stare him she doesn't know if Xin is genius or idiot, he even forgot to use his commonsense.

Kuina angry said, "Turn around and don't peek"

Xin nod and turn around.

"Rustle"

"Rustle"

Xin hear that Kuina is removing her cloth then he heard"Now you can turn around"

Xin turn around then he sees Kuina white shoulder and blushing face then he stared downward but he can only see a strange mark while the other port is covered with a blanket.

System said 'This mark is the mark of flying fish'

Xin said, "Then why it looked like a bird that was about to fly"

System,' Host I'm sure that it was a flying fish that jump out of the water ready glide into the wind'

Xin asks What's that mean then?'

System,' She got water-energy and become the daughter of the sea'

'Even she eat devil fruit the effect of it will remove and she can still swim'

System,'Not only that she can now understand fast and learn fast because of clear mind effect of the water-energy'

Then Xin told all the this that he knows to Kuina.

And Kuina become happy not because she can now learn and improve fast because Xin left a special mark on her.
