Over the next month, the laboratory became bustling with activity. Orochimaru was busy researching methods for mass-producing zombies, while Tsunade and Jiraiya were busy finding various rare medicinal herbs and experimental equipment for him. Tian Yu would occasionally come over to help, assisting him with her Immortal Power. Meanwhile, with Princess Kaguya's help, Tenpi began researching methods for controlling zombies.
That day, Tenpi entered Princess Kaguya's room carrying a stack of documents. Princess Kaguya was sitting by the window, looking at the cherry blossom tree in the courtyard, holding the memory crystal that Tsubasa had given her before.
" Kaguya," Tenpi placed the documents on the table, "Based on the information you provided about Ōtsutsuki Isshiki, and the residual Chakra in the sealing chains on his body, I have finally figured out a way to control zombies."
Princess Kaguya turned her head, picked up the document, and began to read it. It detailed the control method: using the sealing runes of the Uzumaki Clan, combined with the Immortal Power of the Shinobi World, to plant a " Corpse Control Seal " in the zombie's sea of consciousness, taking over its neural control center. This would preserve the zombie's combat power while completely controlling its actions, preventing it from going out of control.
"Very good." Princess Kaguya nodded after reviewing the information. "Now we can deal with Isshiki. He has the bloodline of the Ōtsutsuki Clan within him; once he's transformed into a zombie puppet, his combat power will be more than ten times stronger than an ordinary zombie."
Tenpi nodded. "I've already spoken with Immortal Venerable Tsubasa; we'll go refine it into a puppet today. By the way, Orochimaru also wants to come along; he wants to study the changes after the Ōtsutsuki Clan's bloodline merges with zombies."
Princess Kaguya did not object, and got up to leave the room. "Let's go to the sealing chamber."
Inside the sealing chamber, Ōtsutsuki Isshiki remained chained to the wall. For over a month, he had watched helplessly as Tenpi came daily to collect his blood and Chakra samples, only able to glare at everyone. Seeing Princess Kaguya and Tenpi enter, he roared, " Kaguya! What are you planning now? To experiment on my body? I'm telling you, the clan will be here soon, and you'll all die!"
Princess Kaguya ignored him and turned to Tsubasa, who had followed her in, saying, "Let's begin."
Tsubasa nodded and took out a black ceramic jar—made of a special type of ebony wood, capable of containing death energy and the Chakra of the Ōtsutsuki Clan. He walked to Isshiki's side, and pale golden Senjutsu Chakra emanated from his fingertips, flowing through the chains and into Isshiki's body. Isshiki immediately let out a painful scream, and the black markings on his body began to throb wildly, but were firmly suppressed by the Senjutsu Chakra.
"The first step in creating a puppet is to shatter his soul, leaving only the bloodline power and Chakra within his body," Tsubasa explained to Tenpi and Orochimaru. "However, his soul is too stubborn; it needs to be broken down with Immortal Power."
Princess Kaguya stepped forward, her red Chakra forming a hand that grabbed Isshiki's head. Isshiki's roar grew fainter and fainter, the madness in his eyes gradually fading until they completely lost their light—his soul was shattered and merged into his body and blood.
For the next three hours, Tsubasa continuously used his Immortal Power and sealing runes to modify Isshiki's body. Orochimaru, meanwhile, stood by, rapidly recording the changes in Isshiki's body in his notebook. " The Ōtsutsuki Clan's bloodline has mutated after coming into contact with death energy; their Chakra has become more condensed... their skin has also become harder, making it impossible for ordinary ninja tools to cut through it..."
As darkness fell completely, the transformation was finally complete. The original Ōtsutsuki Isshiki was gone, replaced by a zombie puppet wrapped in golden chains, its skin tinged with pale blue. Its eyes were white, without pupils, yet it could sense the surrounding Chakra fluctuations. Its death aura was even stronger than that of Flying Zombie, but it was firmly locked in place by sealing runes, preventing it from spreading freely.
"Success." Tsubasa put away the pottery jar and looked at the zombie puppet. "Its combat power is equivalent to Star Level Second Stage Ōtsutsuki Clan, and its death energy can suppress their Chakra, making it a Ōtsutsuki invaders."
Orochimaru stepped forward, touched the puppet's skin with his finger, and said excitedly, "Great! Its physical stats are even better than I expected! Next, we can put it with the low-level zombies I've trained and test its cooperative combat capabilities."
Tsubasa nodded. "I've already had a corpse-raising ground set up behind the Immortal Venerable Hall. The concentration of death energy there is suitable for zombie cultivation. Tomorrow, I'll send it there along with your low-level zombie and you."
"Me too?" Orochimaru paused for a moment, then realized, "Alright, the death aura in the Corpse-Raising Ground is even denser, which is perfect for my current training, and I can also observe the growth and changes of the zombies."
Early the next morning, Tsubasa, along with Orochimaru, zombie puppets, and a dozen newly trained low-level zombies, arrived at the corpse-raising ground in the back mountain. This place was originally an abandoned valley, but after Tsubasa transformed it with his Immortal Power, the valley was filled with a faint death aura, and the ground was covered with black moss that could absorb the death aura.
"The concentration of death energy here will gradually increase over time, enough for your cultivation and growth," Tsubasa pointed to the depths of the valley. "There, I've set up a barrier to prevent the death energy from leaking out and to block outside interference."
Orochimaru walked to the center of the valley, took a deep breath, and a satisfied expression appeared on his face. "The death energy here is very pure, much better than in the laboratory." He turned to look at the zombie puppets and low-level zombies behind him, "From today onwards, we will train here and strive to cultivate a zombie army capable of fighting against the Ōtsutsuki Clan within three years."
The zombie puppet seemed to understand his words and began absorbing the surrounding death energy. The low-level zombies also dispersed, each finding a place to cultivate.
Watching this scene, Tsubasa turned to Princess Kaguya behind him and said, "Now that the zombie army issue is resolved, the next step is to integrate the forces of the Shinobi World. The various ninja clans and villages have begun preparations for war, and the moon's defenses have been strengthened. In three years, we should be able to fight against the Ōtsutsuki's support force."
Princess Kaguya nodded, looking at Orochimaru and the zombie puppets in the valley, a hint of relief in her eyes. "I never imagined that the White Zetsu army I created for self-defense back then would now become such a force truly Guardian Ninja world. Child, thank you for giving me the opportunity to make amends for my mistakes."
Tsubasa smiled, reached out and gently patted her shoulder, comforting her, "You're welcome. We are all guardians of the Shinobi World. We have a lot to do in the next three years, let's work hard together."
Princess Kaguya raised her head and looked up at the sky above the valley. Sunlight filtered through the leaves, falling on her face with a warm glow. She knew that the crisis in the Shinobi World was not yet over, and the war three years from now would be incredibly difficult. But this time, she was no longer alone. She had Tsubasa, Ten -Tian Yu, Orochimaru, and everyone Guardian Ninja world, fighting alongside her.
In the valley, Orochimaru sat cross-legged and began absorbing the surrounding death energy. Pale purple Chakra swirled around him, merging with the death energy in the valley to form a strange vortex. The zombie puppets and low-level zombies were also constantly growing, their death energy becoming increasingly concentrated. A battle concerning the survival of the Shinobi World was quietly taking place in this corpse-raising ground.
