Learning Haki

When Xin checks the progress of Unohana, he is surprised to see that she successfully completed the first lesson.

"You did it?"

"Yes, cutting is hard at first but if you get the true essence of cutting you will eventually realize how you should do it."

"Cutting a piece of rock like a piece of paper is the first hurdle in learning Kendo, but after you successfully grasp the essence the next stage will be easy."

"So what's next."

"Next lesson is, Cutting Iron like Mud,"

"Cutting Iron like Mud….. that's interesting."

"Just like the first test, Cutting Iron like Mud is pretty easy, you just need to cut an iron using a wooden sword."

"A wooden sword? I think that's going to be hard,"

Xin took a wooden sword, a cube shaped iron and showed it to her how it was done, with one wave of his hand XIn successfully cut the iron in half.

And the cut is clean and plish like a mirror, no crack or even dent at the end of it as if it cut by something super sharp.

"Se?"

"I only see a flash and that's it, i don't see any technique you use at all, as if you just casually wave your hand and that is it."

"There's a secret to doing it, of course."

"A secret"

"Intent, and Will"

"?" Unohana was confused hearing his answer.

"Like Killing Intent, we can show our enemy our intention but making them feel it without undoing anything."

"And Kendo has that kind of Intent too, Intent using your own will and speed and force to accomplish it."

"And after you successfully learn it, that is the first step in learning Haki."

"Haki?"

"Haki is a mysterious power that allows the user to utilize their own spiritual energy for various purposes. It can be used to sense people's spiritual energy and predict their actions, give the user a protective coating of spiritual energy, and, for a certain group of "chosen ones", overpower the willpower of others."

"What we learning right now is one of the Haki's Technique, the Busoshoku 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"

Xin showed his hand then gripped it slightly, then his hand turned black and the wooden sword also turned black making it look like it was made of metal.

"This is Busoshoku Haki, using it can make your body durable, while putting it on the weapon-making your weapon even more powerful."

Unohana touches Xin's arm and tries to pinch it, it is soft but she can feel the resistance as if she is coated by a thin layer of metal but at the same time it's soft and smooth like skin.

"So after we learn Haki, I can use this technique too?"

"Not really, you still need to train until you finally learn how to use it, and by the way, Haki consumes a large amount of Stamina but being a Captain, i think Stamina is not really a big problem for you."

"I think I can't use my Bankai if I ever use Haki, Bankai is the same as Haki, it consumes Stamina and Reiatsu, using both at the same time will be hard for me for sure."

"Let's start, i dont have the right equipment right now but my past experience is enough for you for now."

"Past experience? Did you teach this to Lieutenant Matsumoto too?"

"No, she still not ready yet, and she don't have talent in Kendo,"

Xin took a bunch of metal balls and put them on the ground, he adjusts the time inside of the training room so that they can train more, after that he checks the other's improvements to see if there are any problems with them.

Besides Unohana and Kenpachi, Byakuya also learns Kendo with Xin, but he is too slow in learning it and having a hard time learning the essence of it.

Next is Rukia and Tochiro who stay at the coldest training room that XIn has, the two of them are on the right track, the only thing they need is time.

Xin also discovers that Rukia's Reiatsu is already at Captain Level, Shirayuki who guardian her is also surprised by the change, it seems that the technique Xin gave starts to bore fruit.

Soin Fon and Yoruichi who are staying at Wing Room have a contest of speed right now, Xin can already see that the wind attribute of their Kido is getting stronger and stronger.

Rangiku, on the other hand, is the laziest of them, she is laying on a sandy beach playing with the ash and sand making various figures.

Based on how good the control she has, Xin knows that she finally masters her own Zanpakuto.

Just like Xin's plan, Rangiku is the first person in Soul Word to master an elemental Zanpakuto like Devil Fruit in One Piece.

As for the others, they are still suffering like Ikkaku and his friend, they need more time so Xin adjusts it for them.

After that, he walks out from the training room and notices that it's already late, he ends to prepare dinner for everyone, and making dinner that can help them in their own training is easy for him.

2 hours later, Xin gives them dinner, but he is confused.

Inoue and others are still not home, it's already late, Xin thought that maybe there's a problem in Hueco Mundo so they are slow.

"Shiro, i'm going out, watch the house while i'm out."

Shiro who is watching TV waves her hand lazy and replies." Yes, Master."

Xin removed his apron and washed his hand, he waved his hand and a door opened to the other side of the world.

When Xin arrives he is surprised by what he sees, a great war is currently happening, Hollow and the people on white are fighting.

"What happened here?"
