Death's Hidden Mobile

The reason they weren't chosen as subordinates was because they were too weak, lacking even the fighting strength of an Espada, and unable to withstand the increased spiritual pressure after being completely Arrancar.

"almost."

Xia Yan stood up, looking at the Hogyoku in front of him, feeling somewhat excited.

"Was it successful?"

A voice sounded beside Xia Yan, and Nelliel slowly walked over.

Xia Yan smiled and said, "That's right."

Nellyel said with a grin, "Then can we proceed with the complete Arrancar experiment you mentioned? I was quite surprised when I learned that Ulquiorra had a second Resurrección; his second Resurrección is much stronger than mine."

Xia Yan shook his head and said, "Don't worry, I'm not very confident about the experiment. If it fails, the soul boundary will be chaotic, and the void will die."

Nellyel asked curiously, "So, who do you plan to use for the experiment?"

Xia Yan said, "Perez."

The first to undergo complete Arrancar transformation was Perez, an Adjuchas-class Hollow, sufficient for the experiment of complete Shinigami transformation.

More importantly, experiments are costly, and Xia Yan cannot guarantee a 100% success rate.

Therefore, the only option was to choose Perez, who was the weakest player and joined the team the latest.

Of course, Xia Yan did a lot of calculations before the experiment to ensure that the risks were minimized.

Nelielu nodded, understanding Xia Yan's considerations.

Xia Yan held the Hōgyoku in his hand and tapped the air a few times with his right hand, activating the Bound Path Heavenly Void, which brought Perez to his side.

"Lord Xia Yan."

Perez arrived quickly, knelt on one knee, and bowed his head.

Xia Yan looked at him and said, "Next, I'm going to conduct an experiment on you that can help you improve your strength, but this experiment has certain risks, so I need your consent."

"Lord Xia Yan, I am willing."

Perez shouted excitedly.

Xia Yan felt a little sorry for him when she saw him like this. She had only used him as an experiment, but he was so excited.

"Let's go."

Xia Yan stood up, picked up a syringe, and led Perez and Nelielu to the void.

A void is a huge pit with a small space, which can greatly restrain the crazy behavior of a broken face.

The Hollowfication of a Shinigami is much simpler than the Hollowfication of a Shinigami.

Because Hollows represent madness, becoming a Shinigami is a way to regain sanity.

However, the intangible form of the Grim Reaper is prone to losing its rationality.

The process of becoming an Arrancar is only shown once in the original work, when Grandfisher escaped after fighting Ichigo Kurosaki, returned to Hueco Mundo and was transformed into an Arrancar. He then returned to the human world to attack Ichigo Kurosaki, but encountered Ichigo Kurosaki's body which was being controlled by a soul, and was eventually defeated by Isshin Kurosaki.

At the time, Grandfisher's face-breaking process was extremely ordinary, but it was extremely painful for the object being broken.

Xia Yan looked at Perez and said softly, "No matter what happens, I hope you can persevere."

"I will."

Perez answered seriously.

Xia Yan aimed the Hōgyoku at Perez, and as the light shone on him, Perez's body made cracking sounds.

"Injectable medication."

Xia Yan injected the medicine he was carrying into Perez's body, causing him to exit the void.

The potion is not a potion that limits the soul's boundaries, but rather a potion that prevents the body from collapsing.

The Hollowfication effect affects the evolution of the body. For example, after Ulquiorra's second Resurrección, his body became more like a beast, but there was no Hollowfication material left.

Other broken faces also represent the process of bodily change.

Therefore, Xia Yan created a potion to stabilize the body's spiritual particles, preventing the spiritual particles that construct the body from collapsing.

"what!"

Perez let out a roar from inside the void, and the white substance on his body gradually disappeared.

Every time a bit of the white substance disappeared, Perez let out a painful roar.

He looked like he was in pain.

Neliel's eyes showed a hint of reluctance.

Xia Yan said, "But I can feel his spiritual pressure increasing."

He himself continued to change, his face bulged, his back arched, and his body grew enormous, transforming into a two-meter-tall, half-human, half-hyena creature.

boom.

The figure leaped up and appeared in front of Xia Yan.

"Be careful."

Nelliel instinctively stepped in front of Xia Yan, but he slowly knelt down and said in a deep voice, "Lord Xia Yan, I feel like I've become much stronger."

"Very well, let's seal your spirit core."

Xia Yan said directly.

Perez's figure shrank, and a mask appeared on his face, covering his arms and cheeks.

But then the white armor vanished, leaving only a band of armor around the forehead, which transformed back into a long sword.

Similar to Ulquiorra's Resurrección form, the first Resurrección has more armor shells than the non-Resurrección form, but the second Resurrección will cause all the armor shells to disappear.

"Success."

Xia Yan breathed a sigh of relief, his expression somewhat excited. The success of his second release proved that he had created a perfect Hogyoku.

With the perfect Hogyoku, one can begin the path of evolution.

Chapter 172: The Path of Evolution

After Xia Yan researched the perfect Hogyoku, he began to prepare to upgrade his subordinates. The first to receive the upgrade was Nelliel. After she was completely transformed into a Shinigami, her second Resurrección was completed. The antelope Arrancar on her head disappeared without a trace, turning into two small curved horns. The white armor on her arms disappeared completely, and her weapon also disappeared.

After Grimmjow's face was shattered, the white armor in his Panther King form disappeared, as did the mask on his forehead, and his body was covered in black fur.

After Harribel's face was revealed, her armor and weapons disappeared without a trace. Fish gills appeared on her cheeks, scales appeared on her body, fish fins appeared on her hands and legs, and a fish fin even extended from her spine.

At this point, Xia Yan discovered two characteristics of Hollows' complete transformation into Shinigami.

The first is that weapons disappear; everyone's weapons disappear.

The second is bestiality, where the body surface mutates, maintaining a human form while possessing bestial characteristics.

Ulquiorra is a bat, Perez is a hyena, Nelielu is an antelope, Halibel is a shark, and Grimmjow is a leopard.

They all exhibited a certain degree of bestiality and lost their so-called ethereal aspect.

This breaks the boundary between Shinigami and Hollows, but it doesn't mean they've risen to a level higher than Shinigami, or even reached the pinnacle of Shinigami.

Even so, Ulquiorra, Halibel, and Nereil are all captain-level fighters.

Ulquiorra's first Resurrection Zz'u was enough to instantly kill Ichigo Kurosaki in his Hollowfied Bankai form, demonstrating his formidable strength.

However, Ulquiorra is ranked fourth because his first Resurrection form is not as strong as Haribel's.

Therefore, when Haribel obtains her second stage of Resurrección, her strength can be considered the strongest among all.

Grimmjow's strength is slightly inferior, but after his Resurrección, his strength is at the level of a captain or higher.

Of course, in addition to being able to become a Hollow, one must also help the Fullbringer achieve complete Hollowfication.

After Tristan completely became a Hollow, he looked like a red-crowned crane with a long beak and legs covered in thick armor and blades.

After Tazhe completely etherealized, he transformed into a gigantic lizard, lying prone on the ground.

After Tsukishima completely became ethereal, it transformed into a giant snake with a serpentine body, long fangs, and thick scales.

As for Ginjo Kugo, he transformed into a giant bull, his body covered by a thick mask, with two bull horns on his head.

The complete intangibility of a Fullbringer also has two characteristics.

The first is that his body completely transforms into a wild beast, just like Kaname Tosen, who became a cricket after his Resurrección.

The second one focuses more on the original characteristics: Tristan's legs, Tsukishima's cold aura, and Tazawa's unpredictable nature. As for Ginjo Kugo, his Fullbring transformation into his second form features a sword with bull horns on its hilt.

After their upgrade, their strength increased significantly.

After their Resurrección, Tristan and Tazé are roughly equivalent to the level of a first-stage Resurrección, while Ginjo Kugo and Tsukishima are equivalent to a second-stage Resurrección, meaning they possess super-captain-level strength.

This is the result of two upgrades, which have led to a significant leap in their strength.

By this time, Xia Yan had five super captain-level combatants and four captain-level upper-rank combatants.

Such combat power is sufficient to deal with the Seireitei when they fought Aizen.

However, during the Thousand-Year Blood War arc in the original work, the Seireitei's super captain-level combat power was also extremely formidable.

Yamamoto Genryusai, Unohana Retsu, Kyoraku Shunsui, and Hitsugaya Toshiro after his restrictions were lifted—these three originally possessed super-captain-level combat power.

In addition, some people regained their power or increased their power to Captain Super level during the Thousand-Year Blood War arc.

Kenpachi Zaraki, the humanized giant dog, Renji Abarai who returned from the Soul King Palace, Byakuya Kuchiki, and Rukia Kuchiki.

These five people—the humanized giant dog, Renji Abarai, Rukia Kuchiki—all killed Quincy who instantly defeated captain-level powerhouses. The other two, Kenpachi Zaraki, were special combatants, and Byakuya Kuchiki, after returning from the Soul King Palace, could have his Shikai comparable to his previous Bankai.

These people all possess strength exceeding that of a captain.

In addition, there are Isshin Kurosaki, Ichigo Kurosaki, Yoruichi Shihouin, Kisuke Urahara, and Mayuri Kurotsuchi could also be added.

Excluding Retsu Unohana and Genryusai Yamamoto, these are eleven super captain-level powerhouses.

Therefore, super-captain-level combat power is not uncommon in the Thousand-Year Blood War arc.

Xia Yan didn't expect the five Super Captain-level combatants he brought with him to become the main fighting force against the Quincy, but as long as they could avoid these...

At least Xia Yan's second objective in coming to Hueco Mundo has been achieved.

So what's the first goal?
