Starting as a pirate, he rose to become the strongest Shinigami in Soul Society.

Chapter 497 This glory, I, Yizhou Tongsheng, will never enjoy alone!

Squad 12, Technology Development Bureau.

The underground building has now been blasted into a huge crater. Standing on the surface of the crater and looking down, wow, you can see all the way down to the fourth floor.

Clearly, everything on top was blown apart.

The members of the 12th Division are digging, clearing, and organizing the area around here.

Vice-captain Hiyori Sarugaki gave instructions while watching Kiryu Hikifune, Orochimaru, and the others climb out of the pit.

Normally, they all looked dignified in their white coats, official robes, and captain's robes, but now they looked as disheveled as could be.

Orochimaru's left arm was completely blown off, covered in blood, with bone spurs exposed. His aura was chaotic, and his spiritual pressure flickered from time to time. His once smooth, long, straight black hair now vaguely resembled an afro.

Mayuri Kurotsuchi was the same; he had a large hole in his stomach, his intestines were hanging out, and blood was flowing out continuously. He looked like he could kick the bucket at any moment.

Kisuke Urahara's hat was all ripped open, and there was a piece of metal stuck in his forehead, probably embedded in his skull. There was a gash on the left side of his mouth, revealing his gums and teeth, and the wound almost reached the back of his head.

Only Kiryu, outwardly, appeared to be unharmed, but his spiritual pressure was extremely low and his face was pale.

"Are you really alright? You call this no casualties? Why don't we go check on the Fourth Division? Let's not hold back our pride." Hiyori Sarugaki said worriedly, looking at their miserable state.

After crawling out of the underground laboratory, Orochimaru finally caught his breath. His spiritual pressure seemed to have stabilized somewhat. He then said, "There's no need for that. Don't let our appearance fool you; we're actually fine."

As he spoke, he seemed to be retching, and the retching became increasingly intense, as if he couldn't stop, which terrified Hiyori Sarugaki.

Don't you vomit before you've even finished speaking?

But before she could speak, Orochimaru suddenly vomited, his mouth wide open as if a head had popped out of it.

Then, the head covered in slime emerged, and then used its two hands to forcefully pry open Orochimaru's upper and lower jaws. In no time, a brand new Orochimaru appeared in front of everyone.

Aside from a significant decrease in spiritual pressure, he seemed perfectly fine.

The body on the ground, which resembled a snake's molt, quickly transformed into spiritual particles and dissipated, leaving nothing behind.

"As expected of you, Orochimaru-san. What kind of technique is that?" Kisuke Urahara asked, leaning against the ruins with great curiosity and surprise.

The slime on Orochimaru's body had completely evaporated, leaving him feeling refreshed. He patted his sleeves and calmly said, "Orochimaru-style Substitution Technique, want to learn it? If you do, you'll have to cooperate with me for some physical modifications first."

This technique was originally developed by Orochimaru as a substitution technique, but it has now been further improved into the "Substitution Technique".

Ordinary people cannot learn it unless they undergo physical modifications. Orochimaru, however, did not undergo physical modifications. He developed it by combining the power of the Eight-Headed Serpent's Devil Fruit with his previous ninjutsu concepts.

It is through the process of shedding its skin like a snake that it can "reshape" itself and thus recover from all injuries.

The downside is that it consumes a lot of spiritual pressure.

Orochimaru had his own quirky tricks, and Mayuri Kurotsuchi was no less so. He haphazardly stuffed his protruding intestines into his abdominal cavity, then pulled a thin needle from his ear and stuck it into his stomach.

Then, the wound that had been bleeding profusely just moments before began to heal at an extremely fast speed. In the blink of an eye, the injury was completely healed, leaving not even a scar. If it weren't for the bloodstains still on her body, Hiyori Sarugaki would have thought it was an illusion.

Seeing this, Kisuke Urahara quickly called out, "Quick, quick, give me an injection of your flesh-building serum too."

Although Mayuri Kurotsuchi often bickers with Kisuke Urahara, this is actually their way of getting along. After so many years of working together day and night on research, they have naturally become close comrades who recognize each other.

So he didn't make things difficult for Kisuke Urahara, and with a flick of his wrist, he tossed a vial of flesh-building serum to Kisuke Urahara.

Kisuke Urahara also inserted a needle into his own neck without any hesitation or doubt, and then the injury healed at a speed visible to the naked eye.

Although Mayuri Kurotsuchi's flesh-building agent seems very powerful, it also has strong side effects. It can only be used once every six months at most, otherwise the body will not be able to withstand it, and the flesh will go berserk, turning the user into a tumor-like monster.

Secondly, the flesh-repairing agent contains multiple compound spiritual particles. After being injected into the body, it will cause the individual to experience a disruption in their control over their spiritual pressure and spiritual particles within a week.

Simply put, impure spiritual pressure can affect the execution of various intricate techniques, such as Kido.

If the side effects are severe, it can even affect the use of one's Zanpakuto.

There's no real solution; the only way to recover is for the body to gradually eliminate these side effects through metabolism.

However, neither Mayuri Kurotsuchi nor Kisuke Urahara expected anything to happen within a week that would require the use of force or violence, so they were absolutely certain about using this flesh-enhancing agent.

Orochimaru, on the other hand, has his own methods. Although it reduces spiritual pressure for a period of time, it is still better than taking flesh-repairing agents, so he doesn't use them.

Hiyori Sarugaki watched as the three of them, each displaying their unique abilities, completely restored themselves in that short time, leaving her utterly speechless.

Kiryuu Hikifune hadn't spoken from the beginning. Although he wasn't injured, he seemed somewhat dazed, with lifeless eyes and a vacant expression.

At that moment, her pupils suddenly brightened, as if her thoughts had returned to her body, and she seemed to come back to life.

Despite her chaotic and weakened spiritual pressure, she didn't care at all. With her hands on her hips, she threw her head back and laughed loudly, "Hahahaha, it's done! My temporary soul is a success!!!"

The big explosion just now was an experiment conducted by Kiryu Hikifune, Orochimaru, and others to temporarily increase their spiritual pressure!

The experimental recipient was, of course, Kirio Hikifune himself.

Orochimaru, Mayuri Kurotsuchi, and Kisuke Urahara each created temporary souls from their spiritual pressure, which they then had Kiryu Hikifune absorb.

As a result, Kiryuu's spiritual pressure instantly amplified to that terrifying level, transforming into substantial destructive power that pierced through the four underground laboratories and blasted apart the Soul-Binding Membrane above Seireitei.

The latest novel is first published here!

Kiryu himself is quite powerful, with a huge spiritual pressure. Orochimaru, Kisuke Urahara, and Mayuri Kurotsuchi are all captains who have reached Bankai level. Among them, Orochimaru and Kisuke Urahara have relatively excellent spiritual pressure.

This injection instantly caused Kiryuu Hikifune's spiritual pressure to leap to a completely different level.

However, because it was his first attempt, he didn't control it well and injected too much spiritual pressure, which caused Kiryu to explode in the end. His spiritual pressure went berserk, and he blasted Orochimaru and the others into the same grotesque state they had just seen.

After a burst of wild laughter, Kiryu looked at Orochimaru and the others with great gratitude and said, "Everyone, thank you so much. If it weren't for the top talents in the industry like you, helping me overcome difficulties over the past ten years, this technology wouldn't have been achieved so quickly. Although the light of the Temporary Soul has only just been born, its glory is destined to be long-lasting. And I, Kiryu, will not keep this glory to myself. I have decided to release the Temporary Soul technology in everyone's name!"

Orochimaru and the others accepted Kiryu's thanks without any hesitation.

After all, it has taken them a considerable amount of time and effort over the past ten years.

Of course, this process was also a collision of ideas among these cutting-edge scientists, from which everyone benefited greatly and gained a lot.

However, when they heard Kiryuu say that he wanted to release this technology in everyone's name, Orochimaru, Kisuke Urahara, and Mayuri Kurotsuchi's previously somewhat relieved smiles froze.

The three of them immediately changed their expressions and expressions!

Is this a joke?

The reason we've gone to such lengths to help you complete this temporary soul technique as quickly as possible is to send you away to the Ascension Zero Division, making room for us to become the captain of the Twelfth Division.

And then, after all that hard work and nearly ten years of effort, the results are finally in, and all that's left is for the Zero Division to come and inspect them and take you to the heavens, and suddenly you say you want to share all of this with us.

Will this work? What if we share this and the Zero Division fails to advance? Wouldn't all our efforts have been for nothing?

Kisuke Urahara reacted the fastest, leaping to his feet and immediately declaring righteously, "Captain Kiryu, as colleagues and members of the Technology Development Bureau, helping each other is our duty. But if you say things like that, we'll get angry!"

Mayuri Kurotsuchi also sat up with a start and said, "That's right, I, Mayuri Kurotsuchi, still have some shame. This temporary soul technology, from scratch, you've been researching it for almost three hundred years, and we've only participated in the last ten years or so. Judging from the problems we encountered during this time, there's no doubt that with your level of expertise, you'll solve them all naturally sooner or later. We just helped you speed up the process. If you're going to talk about co-authoring this technology, aren't you mocking us for stealing your fruits of labor?"

In fact, without the involvement of Orochimaru, Kisuke Urahara, and Mayuri Kurotsuchi, Kiryu Hikifune would have continued to cause trouble for at least another 150 years.

However, as Mayuri Kurotsuchi said, these are all just a matter of time. Technically speaking, Kiryu Hikifune can complete the task on his own!

Kiryu seemed taken aback by their intense reaction and was momentarily stunned. Just as she was about to say something, Orochimaru patted her on the shoulder and said, "Captain Kiryu, if you really want to thank us, treat us to a meal. We're all top talents in our field; we know what's ours and what's not. Besides, don't you have a dream of joining the Zero Division? We're all from the Twelfth Division, and the reason we're working so hard together is to support your dream!"

In short, the three of them gave Hikifune Kirito a good talking-to, pouring all sorts of nonsense about friendship, the will of the Twelfth Division, and bonds into his head.

Kirio Hikifune was incredibly moved!

"Although I've heard that once you go to the Zero Division, you can't easily interfere in the Seireitei's affairs, if I really do go to the Zero Division, please feel free to ask if you need my help in the future!!!" Kiryu Hikifune said in a firm and powerful tone.

While they were chattering away, Bann, Kyoraku Shunsui, Ukitake Jushiro, and others arrived.

It wasn't for any kind of warning or anything. After all, Hiyori Sarugaki had already said in her report that it wasn't necessary. So, apart from Jushiro Ukitake who was there to do serious business, everyone else was just there to join in the fun.

"Quick, make way, make way, let me see what's going on! What's going on!?" Bane squeezed in with great interest, shouting excitedly.
