Bleach: Getting Stronger Starting from Teaching at the Spiritual Arts Academy

These spirit remains are very different from the spirit remains they previously found in Soul Society.

Tetsuya Miyamoto selects qualified souls from the mortal world and uses these souls as samples to cultivate the spirit remains of the Grim Reaper from embryonic stage.

These remains have no records of spiritual particle data!

The Twelfth Division's spirit particle detector was also unable to detect their spirit particle data from the database.

In other words, these spirit remains can perfectly lurk in the Soul Society!

"Fortunately, we learned about the location of Tetsuya Miyamoto's experimental base in advance from the Mizutani family... These spirit remains haven't grown to a usable level yet, otherwise the Soul Society's Seireitei would be in chaos." July sighed inwardly.

If these hundreds of unrecognizable spirit remains were allowed into Soul Society, the consequences would be unimaginable!

"It seems that Miyamoto Tetsuya hasn't been using the technology to accelerate the maturation of embryos and infant-shaped spirits for very long." July flipped through the documents, trying to find the technology for accelerating the maturation of spirits.

A moment later, he found information on the technique of accelerating the maturation of spirits in one of the folders.

"Spirit growth agent... its main ingredient is actually an extract of the unseen?"

This discovery immediately gave July a jolt of energy.

July and Aizen had already tried to combine Hollows with Shinigami spirits, and the Shinigami spirits inevitably underwent uncontrollable mutations.

However, Tetsuya Miyamoto's spirit growth agent contained a void component.

"That Void entity should be in the lab." July's heart stirred, and she spread her spiritual senses to search for the Void's whereabouts.

In the next instant, July used Flash to reach the end of the laboratory.

There is a door protected by a spiritual energy shield.

The shadow space dispersed, and July instantly passed through the spiritual particle shield and entered the door.

Inside was a room of about 100 square meters. In the center of the room was a glass jar, which was much larger than the glass jar outside that contained the remains of the spirit.

The glass jar was filled with a nutrient solution rich in spiritual energy, and countless tubes connected the soul inside through the jar.

Chapter 211 Looting the Battlefield

July confirmed her guess. After using the Shadow Dimension to pass through a layer of spiritual energy shield, she saw a very different glass jar.

"The Arrancar Vasto Devi?" July was slightly taken aback.

A virtual being with a human face was immersed in a glass jar of spiritual nutrient solution, with countless tubes inserted into its body through the jar.

The upper body of the human-faced Void resembles that of a human female, but its lower body lacks legs, instead possessing limbs resembling octopus tentacles, the color of which matches the Void's long, silvery-white hair.

"It looks like a corpse... No wonder I didn't sense any strong spiritual pressure fluctuations when I was outside the room." July frowned.

After close observation and perception, he discovered that the human-faced phantom was not a living creature.

The tubes inserted into the human-faced avatar were injecting some kind of medicine into her body to maintain the avatar's vitality.

In July, after searching the room, she quickly found the information about the human-faced phantom.

Then, in July, an astonishing discovery was made—

This human-faced creature is actually born with a broken face!

More accurately, she was half-human and half-phantom.

Miyamoto Tetsuya also conducted inhumane experiments.

He experimented with human spirits, causing them to conceive children born from the union of a human and a spirit.

The human-faced phantom we saw in July was the result of this experiment.

She was born with a broken face and possesses the ability to regenerate at supersonic speed.

Tetsuya Miyamoto's spirit growth serum was created by extracting the blood of this human-faced Void.

Perhaps because he was half-human and half-hollow, the blood containing the Hollow power of the human-faced Hollow did not cause the Grim Reaper to undergo uncontrollable mutations.

In July, I came across a stack of experimental records and saw many failed attempts to create half-human, half-ethereal entities.

The container's origin and the date of the experiment were also noted on it; they were mostly from residents of Rukongai who possessed Shinigami qualifications.

At this point, July quickly figured some things out.

When he traveled with Yamamoto Genryusai Shigekuni and others, most of the shrines of dubious origin that he saw were related to the lord of hell.

The core members of these shrines are basically spirit remains created by Tetsuya Miyamoto.

Miyamoto Tetsuya used these spirit remains that had infiltrated Rukongai to spread a belief in connection with the Lord of Hell, and then selected suitable vessels from among the believers to conduct human experiments.

"Miyamoto Tetsuya's ambitions are quite large... He's already set his sights on the Void so early," July thought to herself.

After numerous attempts, Miyamoto Tetsuya likely discovered the limitations of the Shinigami spirits and began to work on other types of spirits.

After countless spirits with the potential to become Grim Reapers were sacrificed, this half-human, half-void was born.

Furthermore, this human-faced creature is not perfect; it seems to possess some unknown innate defect.

She grew very quickly, transforming from an infant to an adult in just seven days, but died suddenly after only a short period of time.

Even so, this human-faced Void was a miracle born by chance, and Tetsuya Miyamoto continued to make many attempts afterward, but still failed to replicate it.

Other experimental subjects underwent uncontrollable phagocytosis and aberration during the embryonic stage, devouring the mother and then completely transforming into phagocytosis.

Tetsuya Miyamoto also discovered that the blood of the human-faced ghost was very special, and could promote the growth and rapid regeneration of other spirits.

They then used technical means to maintain the activity of the human-faced ethereal spirit, extracting blood from her body to create a spirit growth agent.

"It seems that the spirit remains being cultivated in the laboratory outside all contain trace amounts of void power," July thought to herself.

The spirit growth agent created by Tetsuya Miyamoto was made using the blood of the Hollow-faced Human, so it inevitably contained Hollow spirit particles.

Using it to heal injuries, like Miyamoto Tetsuya did, is fine, but it's only for short-term use, and the small amount of ethereal particles won't put a significant burden on the spirit body.

However, those spirit remains that have been matured by using spirit growth agents for a long time will accumulate more and more ethereal particles.

In July, she even felt that there was a possibility that they might become unreal.

He decided to take some of the spirit remains with him and place them in his laboratory to observe their growth.

The Hollow-faced Human in this secret room is also not to be missed. This naturally born half-human, half-Hollow is quite special and is of great help to the study of Shinigami Hollowfication and Hollow-Shinigami transformation.

Most importantly, he wanted to try to cultivate another spirit body of Shikagu Hakunsai using the spirit growth agent!

The Seireitei's first generation of spirit body technology was unable to cultivate spirit bodies that could grow, resulting in spirit pressure cores that were too fragile to withstand Shikatori Hakunsai's spirit body.

Miyamoto Tetsu also made some iterations to the spirit skeleton technology, which can cultivate spirit skeletons from the embryonic stage.

This kind of spirit has a certain room for growth and also eliminates the problem of personality defects.

By using the spirit particle growth agent to accelerate the maturation of the spirit skeleton, the spirit body of the spirit skeleton can be quickly accelerated to the limit that the spiritual pressure core can bear.

The development of the spirit body also promotes the development of the spiritual pressure core.

This greatly shortens the growth time of the spirit.

Perhaps this ripening technique can be used to cultivate a spiritual pressure core capable of bearing the spiritual body of Shikatori Hakunsai.

He needs to go back and observe and test to see where the limits are for spirit remains cultivated in this way.

There are many ready-made observation and testing subjects in the outside laboratories. The spirit skeletons that are being cultivated are basically cultivated using accelerated growth methods.

In July, he found information on drugs that could maintain the activity of the human-faced ethereal spirit. After reviewing the information, he had a clear understanding of the situation.

Miyamoto Toru was also prepared to move the laboratory at any time. The life support pod of the Hollow was detachable, and in July, he spent a lot of effort to remove it.

In July, the life support capsule and the drugs to maintain vitality were packed into the spiritual space pocket.

Fortunately, I have the Spirit Particle Space Pocket, otherwise it would have been difficult to take this large life support capsule with me.

They didn't even spare the documents in the secret room; July packed them all up and took them with her.

After confirming that nothing was missed, July once again opened the Shadow Space and crossed the spiritual barrier of the secret chamber.

As soon as July came out, I saw Yoruichi leaning against the wall.

"Is there anything else you need to pack, teacher?" Yoruichi Shihouin asked. "We've finished organizing all the materials here."

“I also want to take some remains with me,” July said.

"Then let's take all the unbroken life support cells. Leaving them here will only benefit the people in the Twelfth Division," Yoruichi Shihouin said with a smile.

Currently, only the 12th Division among the 13th Division has a laboratory for researching technology, and the Stealth Mobile Unit only takes the spirit remains back as proof of their mission.

These types of mission credentials for experimental subjects are eventually sent to the 12th Division for processing by Kirio Hikifune.

"My spiritual space pocket isn't big enough," July said.

There are still one or two hundred intact life support cells. July's spiritual space pocket already contained a lot of miscellaneous things, so it simply couldn't hold that many life support cells.

"Is the teacher's spiritual space pocket not enough?"

“That’s easy!” Yoruichi Shihouin took out an inconspicuous scroll. “I have one here that’s quite large; I’ll give it to you, sir.”

July took the scroll handed to him by Yoruichi Shihouin, and after examining the spiritual space inside, he was immediately astonished by its size.

"This spiritual space is huge. Such a large and stable spiritual space... the technology behind this scroll is truly remarkable." July was somewhat surprised; this was the largest spiritual space he had ever seen used for storing things.

“This ‘Heaven-sent Armor’ contains a sizable ‘Valley Space,’ which is not a spiritual space expanded using demonic arts, so its structure is very stable,” Yoruichi Shihouin explained.

"This area is more than enough to accommodate all these life support cells," July remarked.

With the assistance of members of the Covert Task Force, it took some time to dismantle the intact life support pod in the laboratory.

In July, the intact life support pods were packed up and taken away, while the covert task force took away the damaged life support pods and the remains as mission credentials.

The three Onmitsuki approached Yoruichi Shihouin and said, "Lieutenant, the remains in the living quarters upstairs have been dealt with."

The strongest of the spirits in the living area above were only comparable to ordinary Shinigami soldiers, and they were powerless against the three elite Shinigami.

If they weren't afraid they would sound the alarm and allow Miyamoto Tetsuya to escape, they wouldn't have needed to sneak in all the way.

After cleaning up the laboratory, the group returned to Soul Society through the portal.

In July, she also participated in the mission and went to the First Division with Yoruichi Shihouin.

Yoru Shihouin informed them of their return to Soul Society early in the morning via the messenger device. At this time, the captains and acting captains of each division were waiting in the First Division.

The vice-captain of the First Division, Chojiro Sasakibe, was already waiting at the door.

July did not try to hide the injury on his hand, and Chojiro noticed it.

"The captains are all waiting inside, but do you need to have your injuries treated first?" Chojiro asked.

"No need. This injury can't be healed in a short time. With the help of the healing method, the injury won't worsen." July gently shook her head.

The body is not yet fully healed enough to undergo super-fast regeneration; the lost flesh and blood cannot grow back in a short period of time.

"You've had a tough time. It seems this mission will be quite difficult." Chojiro Sasakibe spoke a little more to the wounded.

"I'm fine, Vice Captain of the Sparrow Division, please lead us inside," July said with a smile.

Chojiro Sasaki nodded slightly and led the two into the First Division.

After the three arrived at the First Division's council chamber, everyone's attention was drawn to the injury on Shikatoshi Nanatsuki's hand.

"Oh no—how did you get such a bad injury!" Kiryuki grabbed Shikatoshi Nanatsuki's left hand, and looking at the exposed bones in his index and middle fingers, a look of heartache immediately appeared on his face.

Kiryu now regards Shikari Nanatsuki as a close junior, and seeing him so badly injured, he felt very sorry for him.

"Don't worry, it was just a sword technique that exceeded the limits of my spirit body. I'll just need to go back and get some treatment," July said.

"Come with me to the lab later, and I'll prepare some medicine to nourish your spirit," said Yizhou Tongsheng.

"Is the enemy this time so powerful that they could inflict such serious injuries on Shikatori-kun!" Kyoraku Shunsui raised an eyebrow. He knew very well that Shikatori Nanatsuki's current strength was definitely enough to serve as a captain, yet he was still seriously injured.

“I didn’t expect Miyamoto Tetsuya to have become so much stronger. The Mizutani family doesn’t know the specifics about his strength either, otherwise we should have sent two more captains over,” said Hikifune Kiryu.

“He modified his Zanpakuto, making it quite formidable. I didn’t want to engage in a prolonged battle with him, so in order to quickly defeat him, I had to use sword techniques that exceeded the limits of a spirit body,” July explained.

"He actually modified his Zanpakuto?" Kiryu Hikifune was somewhat surprised and regretful. "Miyamoto Toru was also an excellent technical talent, but unfortunately he went astray and went against the grain of the Seireitei."

A Zanpakuto can be considered a part of a Shinigami's soul; it is not something that can be easily modified.

The slightest carelessness could lead to very serious consequences.

The fact that Miyamoto Toru can modify his own Zanpakuto is enough to prove that his technical ability in the field of spiritual research is extraordinary.

"Has Shikatori-kun developed an even more powerful sword technique? You've suffered such a serious injury this time, why don't you just stay in the Fourth Division and recuperate properly?" Unohana Retsu said with a smile.

Even though Retsu Unohana's eyes were slightly narrowed, Nana could still feel the burning intensity in them.
