"Let's go. I want to see how much you improve in these past months," Xin said.
"Let me do it first, Hina excited," Hina said.
Xin looked at Hina and asked," How is your way of speaking suddenly changing? Is that a new trend?"
Hina's way of speaking suddenly changed from normal to a childish one, and she added the first-person pronoun, with Xin know in her original way of speaking on the original story.
"I think it's much better to speak like this, I only do this when I'm home so why not use it, Hina explains," Hina said.
"Well okay, if you're happy then continue it,"
Hian cheerful nodded, she thought that Xin will feel weird in the way she speaks but she did not expect Xin to accept it as if this is only normal.
"Ok let's see if you fully develop your ability," Xin said.
"Self Binding Giant Iron knuckle"
Hina's hand suddenly deforms and changes to a black color and metal bars appear from it, like robot parts, the metal bars combine and form an oversized metal knuckle in her arms.
Hina showed it to him and said," How is it, Hina asked."
Xin looked carefully and touched the durability and flexibility, seeing that she could easily use it and did not hinder her movement, Xin nodded.
"You're good, the metal can easily block swords and bullets, but if you want to make this thing stronger, you need to develop your own Haki," Xin said.
"Haki is an advanced technique, Vice Admiral Crane said that I need to improve my physical strength for me to start training my Haki, Hina explains," She said.
"Grandma is right you need a strong body if you want to train your Haki, but there's something more important than that, you need to train your 'WILL'," Xin said.
"Will? Is that useful, Hina concern," She asked.
"Why not let's try? Ain stands beside Hina, let's do a small experiment," Xin said.
"Sure," Ain walks beside Hina while Xin standing at them.
"Okay get ready," Xin then stood and expanded his 'Will' to them.
"Zoom
Hina and Ain subconscious raise their guard, they don't know why but they feel that Xin is going to hit them in their head.
They wait but nothing hits them, they look and see Xin ginning at them, he is still standing in the same possession without moving.
Looking at their confused face, Xin knows that they feel it," So why do you guys suddenly guard?"
"I feel that you're going to attack me, Hina said," She said.
"Me too, I even thought that it's too late to block," Ain said.
"That's my 'Will' i did not hit you but actually i did not, let's make it simple 'Will' is a type of spiritual power, power of the mind, I use my power if mind to transfer my thought that's why you feel that i'm going to hit you"
"That is the first Haki, the Haoshoku Haki, mine is different but it already near on original"
"Not only that," Xin raises one of his arms and hardens, Xin's arms change into a gold-silver color, not like the original color of Haki, Xin has a different Haki type.
"This is the Will Materialize, in short, Busoshoku Haki, this is the second type of Haki"
"Busoshoku Haki is a form of Haki that allows the user to use their own spiritual energy to create, in essence, an invisible armor around themself, providing incredible offensive and defensive capabilities."
"This is the thing that Hina should learn first if you combine it with your devil fruit, your offensive, and defensive capability will shot up"
"And lastly is Kenbunshoku Haki is a form of Haki that grants the user a sixth sense that allows them to sense the presence, strength, and emotions of others, as well as gain limited precognitive abilities."
"This is the only Haki that i still did not master well, i can sense presence and strength but not the emotions of others"
System,' Host, you will never master Kenbunshoku Haki, did you forget that Haki is useless for you even the ultimate form of it is useless because you already know what will happen next'
Xin thought that the System is right, he almost knows the future.
System,' Not only that but your quest to change the plot is also actually to help you to develop Kenbunshoku Haki, you don't know but knowing the future will only stop your Kenbunshoku Haki training that's why we trying to change the future'
'Then I can still learn Kenbunshoku Haki in the future?' Xin asked.
System,' Of course host, don't worry, you will learn it after the who Plot of this world change beyond recognition'
Xin sighs and looks at Ain and Hina," Do you guys want to develop your own Haki?'
Hina and Ain hurry nodded, if they can learn it early then they don't need to waste too much time to learn it in the future.
"Well, I'll help you guys later, let's continue," Xin said.
"Self Binding Armor v Part: Iron Knight Boots"
From Hina's legs, back armor boots appear," I can use this two perfectly but i can't still master the whole body armor"
Xin then take out a weird punching machine," Let's try your power while wearing that armor,"
Hena nodded and used her full power to punch the red sickle in the middle.
"HA!"
*Bang
"Ding! 800 kilogram, 1763 Pound-force"
"Wow, Hina-chan you're strong," Ain said.
"Why not try it Ain?" Xin asked.
Ain excitedly nodded, she stood in front of the punching machine and used it.
"Fang Interpolation"
Ain used his finger and pierce it, sticking to the punching machine.
*Bang
"Ding! 602 kilogram, 1327 Pound-force"
"Not bad for a martial art skill that uses speed and fluid motion," Xin said.
"I still need time to master the 'Water Stream Rock Smashing Fist Technique'," Ain said.
"That's good, we still have one week before the assessment, I will help your training while I will find a training partner for you guys….."
"Well I forgot, I actually have a perfect training partner for you guys, also Stella-nee, Koala, you guys are going to join their training," Xin said.
"Yes Young Master," Stella said
"Okay Big Brother" Koala replied.
Vice Admiral Crane who is looking at them feels nervous, Xin has a big problem right now, Xin actually develops Haoshoku Haki, she needs to talk to him later about the danger that is waiting for him if the World Government discovers that he awakened that Haki.
