The Alchemist in Bleach

Not to mention that spirit alchemy has a very promising future, while what does it matter if a Zanpakuto has heaven-defying abilities?

The battle between Shinigami is a battle of spiritual pressure!

Soi Fon's two-hit special attack is strong, right?

But if the spiritual pressure is strong enough, it can erase the mark of the first attack!

Kira's gravity must be twice as strong, right?

But does he have enough spiritual pressure to multiply infinitely?

Isn't Aizen's Kyoka Suigetsu strong?

But shouldn't we still try every means to weaken and avoid the captain?

Therefore, Zanpakuto are an important fighting force for Shinigami, but not the only one; spiritual pressure is!

Therefore, Ichiro is more interested in the increased spiritual pressure from Shikai and Bankai than in the abilities of his Zanpakuto.

"Brush~"

"Hmm? You're back so early today. Have you finished studying?"

"Yeah, there's nothing left to learn, I can only rely on hard work and perseverance... Sigh... It's tough..."

“…” Urahara paused for a moment, then managed to utter, “Pervert!”

Ichiro ignored his words and instead laughed as he looked at the Zanpakuto that had appeared in his hand.

"Finally found it. It's strange that even with the power of your nobles, it's so hard to find."

"After all, there's no demand. Everyone wants shallow Zanpakuto, and there are basically no fully formed ones available." Urahara shrugged, somewhat helplessly.

Only the people of Rukongai would consider this kind of Zanpakuto. They all use brand new Asauchi directly. However, Ichiro already has that, and now he needs a finished Zanpakuto for data comparison.

Of course, Ichiro could do it himself, but what if he fails?

So, to be on the safe side, he asked Urahara and the others to help him find one himself.

"You haven't given up on your research yet? I still think Dao Chan is the most reliable."

"There are many options; we must trust science!"

Urahara's lips twitched: "Science... Last time I met a guy from the future in Rukongai, and according to him, the existence of Soul Society itself is unscientific..."

"I've said it so many times, so-called science is a way of thinking, not a specific phenomenon." As he spoke, Ichiro jumped off the bed and began to carve a transmutation circle on the floor. "Just like my method of studying Kido, I break down and classify all the incantations, study them, and then summarize their similarities and differences. That's the simplest scientific way of thinking."

Science is not about denial, but about questioning and then verifying. And it is not something that can be permanently denied after one verification. There are relative truths and absolute truths in the world.

Relative truth is truth with a certain scope; beyond a certain scope, it is no longer truth. Absolute truth has no scope; it is the sum of countless relative truths…

"Wait! Stop reading!" Urahara shouted as soon as Ichiro began to speak.

It's not that he dislikes it; as knowledge for the future, it's impossible for him to say he's not interested. But! But!

But the premise is that it needs to be made clear!

Ichiro himself only had a vague understanding; he was the type who knew how to do it but couldn't articulate it, which made it seem incredibly complicated, like a tongue twister. After hearing it a few times, Urahara was already scared...

Instead of listening to Ichiro, it's better to see how he does it and then follow his example; that's more efficient.

Ichiro shrugged and continued fiddling with the transmutation array on the ground; he was fairly aware of his own abilities.

A moment later, Urahara placed his Zanpakuto on the alchemy circle, then walked to the side and watched Ichiro perform.

Ichiro placed his hands on the transmutation circle, closed his eyes, and activated the transmutation circle. As the transmutation circle shone brightly, streams of information appeared in Ichiro's mind.

Alchemy, simply put, involves three steps: understanding, decomposing, and reconstructing. Understand the framework, then decompose it, and finally reassemble it into other structures.

As long as the quality and quantity are equal, and within the practitioner's capabilities, anything can be crafted!

This is alchemy!

Following scientific principles, yet possessing unscientific abilities!

Of course, what Ichiro is doing now is only the first step: understanding.

He needs to acquire comprehensive data on Zanpakuto, then analyze and compare it to find the principles behind their Shikai, thereby mastering his own Shikai, and even...

The mimicry-style Shikai that breaks free from the Zanpakuto!

This is Ichiro's current research goal, and he has already completed most of it, only lacking the last few core pieces of the puzzle!

Although only one semester has passed, Ichiro has made great progress, especially after his spiritual alchemy began to take shape!

The initial formation of spirit particle alchemy means that Ichiro has basically transformed about half of the research results from his previous life!

The firearms are complete; all the small firearms are finished!

It even incorporated adjustments based on the Ghost Path, making its firepower far superior to the heavy firearms of its predecessor!

The body was forged, and the achievements of the previous life were fully absorbed! Furthermore, by combining this with the knowledge of Soul Society, it reached even greater heights!

The gunpowder was successfully refined, and it was 80% replicated!

The only downside is that he only completed about 10% of the reconstruction work on the various transmutation arrays he learned in the previous world.

In fact, this part is the essence of what Ichiro learned in his previous life!

The above are just the core parts of Ichiro's combat system, which are the ones that have the greatest impact on combat power. This part is the core of Ichiro's alchemy, so this one alone accounts for nearly 50%!

Don't be fooled by this messy part; it's precisely because of this messiness that it's so important, because the world isn't made up of a single substance, but of all sorts of different substances (Fullmetal Alchemist).

Alchemists like Ichiro usually specialize in a single substance to maximize their combat power, but they use all sorts of transmutation circles when conducting research.

Just like how you can't use any one of the basic operations (addition, subtraction, multiplication, and division) to complete all the calculations, it's important, but not powerful.

So, that's why Ichiro stays at school; his period of rapid growth isn't over yet...

Chapter Twenty-Two: Ichiro vs. Urahara!

Besides the improvement in my skills, two other things happened this semester.

First, Sugo was expelled from school for harassing a female teacher. According to Ichiro's rumors, he was said to have died tragically in Rukongai. Because the whole incident was a bit strange, no one mentioned it anymore.

The second one is just as Suzuran Tsukiyoichiro said. She skipped a grade shortly after entering their class and is already a fourth-year student this year. At this rate, she should graduate soon.

However, this has nothing to do with Ichiro!

……

"clang!"

"Hado #31: Red Fire Cannon!"

"Sing out, Red Princess!"

"The Crimson Shield!"

"boom!"

In the vast underground space, Ichiro and Urahara faced off with their swords drawn, while Yoruichi watched with great interest, occasionally popping a snack into her mouth.

"Hey, isn't using Shikai a bit too much of a rip-off?"

"Clang~" Urahara tapped the stone next to him and said in a nonchalant tone, "If you're not convinced, you can use Shikai. If you won't go, then I will!"

"Explode, Red Princess!"

"Shhhhhh!"

Suddenly, a large number of shockwaves flew out from the blood-red light shield in front of Urahara, raining down on Ichiro.

At this critical moment, Ichiro first quickly sheathed his sword, then raised his left hand forward horizontally.

"#=&+*?*-*_#**?#，?，~Binding Spell Thirty-Nine: Round Gate!"

As Ichiro's lips trembled, a pale blue shield appeared in front of him, blocking all attacks!

Immediately afterwards!

"~&-/= Binding Technique Twenty-One: Crimson Smoke Escape!"

"!#!*~=/.﹉#，/$)=*/_#;…..|[[].·$`＇「GBP.] Binding Spell No. 26·Curved Light!"

With three high-speed incantations of Kido unleashed in succession, Ichiro's figure completely disappeared from the battlefield, while the large amount of smoke generated by the Red Smoke Release also obscured Urahara's vision, causing a double interference!

Urahara, looking around the field, appeared unusually serious, his attention completely focused and alert, a far cry from his earlier relaxed demeanor.

He had only heard Ichiro's introduction to high-speed chanting before, but had never actually seen it. So although he felt it was amazing, he didn't really grasp its significance. Now that he had seen it with his own eyes, he realized that he had still greatly underestimated this Kido technique!

In just over three seconds, three consecutive Kido spells were fully chanted. If the spiritual pressure were stronger, it would be possible to completely suppress the enemy with firepower!

Fortunately, Ichiro's spiritual pressure wasn't very strong, and the battle had already depleted some of it, meaning he only had one choice...

……

Ichiro moved continuously within the smoke screen using Shunpo, while the spiritual alchemy technique in his sleeves glowed faintly, assisting him in leaving behind a series of Kido seals and concentrating and converting the spiritual particles in the air to restore Ichiro's spiritual pressure to the maximum extent!

'Urahara will definitely think my spiritual pressure is insufficient, and he'll resort to close combat next, so he'll probably switch his sword to... so...'

"...Hado #31: Red Fire Cannon!"

"Wake up, Honghime!"

"What!?"

Urahara stared in surprise at the fireballs flying towards him, his pupils shrinking. He was a little confused as to how Ichiro's spiritual pressure had recovered, but the matter was already settled, and he could only try to find a solution.

Urahara had a deep understanding of Zanpakuto, and inspired by Ichiro, he developed almost all of the Shikai forms from the original work.

Cry out, Benihime! She is adept at manipulating the red spiritual pressure extending from her blade, making her highly functional.

Wake up, Red Princess. You excel in close combat, such as slashing and thrusting, and are highly lethal at close range.

"boom!"

However, while his offense was strong, his defense was weak. After cutting through one of the Red Fire Cannons, Urahara fled in a sorry state, dodging several more Red Fire Cannons fired by Ichiro.

"Sing out, Red Princess!"

Of course, Urahara wasn't idle while fleeing. He took the opportunity to change the form of his Zanpakuto, then threw a few pills into his mouth before turning around and charging towards the several Red Fire Cannons behind him!

"boom!!!"

To Ichiro's astonishment, Urahara instantly thrust his sword several times at the oncoming Red Fire Cannons, and all the Red Fire Cannons that were pierced by him turned into spiritual particles and dissipated!
