For the previous Zhang Miao, even someone like Kaguya or Nagato and Obito were a towering mountain hanging over his head.
But things had changed now. Zhang Miao had become a "Nether King" and Kaguya was no longer a threat. Therefore, he had no reason to obstruct Black Zetsu's resurrection plan.
So, he decided to adopt a laissez-faire attitude towards Black Zetsu.
"Anyway, with me here, the ninja world won't perish. Let him stir up trouble. I'll just watch, so I won't get too bored on the path to godhood."
With this thought in mind, Zhang Miao's life in the Land of Waves returned to normal. The only difference was the addition of a "little tail" behind him – Black Zetsu.
To confirm Zhang Miao's credibility, Black Zetsu had been following him ever since he arrived in the Land of Waves, observing everything he said and did. Even when sleeping at night, Black Zetsu did not give up on his surveillance.
Of course, Zhang Miao was well aware that Black Zetsu was monitoring him constantly. This feeling wasn't pleasant, but he endured it to collect Black Zetsu's Ninja Fragments.
Although Black Zetsu had been in a constant state of surveillance, he had never revealed himself in front of Zhang Miao. If it weren't for the daily system notification that rang precisely in the early morning, Zhang Miao would almost forget that Black Zetsu was watching him.
"He can watch all he wants. After all, I have nothing to hide. I'll just pretend he doesn't exist."
With this thought in mind, Zhang Miao quickly grew accustomed to Black Zetsu's surveillance.
This situation continued for about half a year. When the "Kamikage Building" that Zhang Miao had toppled with the Byakugan's pressure was rebuilt, Black Zetsu appeared before him again.
"Sir, I now believe that you are mother's ally. With your abilities and strength, you could easily dominate the ninja world. Yet you haven't done so. It's evident that you and Kaguya-sama do indeed have a formidable enemy to face. I must revive Kaguya-sama as soon as possible. Farewell, sir!"
Having said this, Black Zetsu bowed to Zhang Miao. While bowing, his half of the body sank into the floor, indicating his intention to leave.
Seeing this, Zhang Miao quickly raised his hand.
"Wait... Wait a moment!"
"Hmm?" Upon hearing Zhang Miao's words, Black Zetsu immediately halted his descent, looking puzzled. "May I ask, sir, if there's something else?"
Faced with Black Zetsu's question, Zhang Miao didn't answer immediately. Instead, he issued a command to the system silently in his mind.
"System, help me retrieve the Black Zetsu Ninja Fragments required for recruitment."
Black Zetsu had been monitoring Zhang Miao for a considerable amount of time, and Zhang Miao had been collecting Black Zetsu's Ninja Fragments for the same duration. The required fragments for recruitment had already been collected. With a single command, the system immediately retrieved enough of Black Zetsu Ninja Fragments.
Seeing the fragments of Black Zetsu scattered on the ground, Zhang Miao bit his finger to form hand seals.
"Summoning Jutsu!"
As Zhang Miao uttered these words, a puff of white smoke suddenly rose from the ground with a loud "bang." When the smoke cleared, a shadowy figure immediately appeared in front of him, and the system's notification sounded.
"Ding! Congratulations to Your Holiness on recruiting 7-star Kage-level, Black Zetsu, and gaining access to this ninja's chakra reserves. Since this ninja has exceptional mental abilities, my lord has obtained the specialty - Mental Enhancement, doubling perception capabilities, doubling resistance to genjutsu, and control abilities!"
Originally, Zhang Miao's perception range was around two kilometers, which was the distance he could use the Mind Reading technique. Now it had doubled to about four kilometers. This undoubtedly made his future actions much more convenient.
So, upon hearing the system's notification, a smile immediately appeared on his lips.
"A range of four kilometers should be sufficient, and the doubled resistance to genjutsu and control abilities is truly an excellent specialty!"
With these thoughts in mind, Zhang Miao turned to look at Black Zetsu, who was standing beside him. He found that Black Zetsu was staring at the Black Zetsu he had just recruited, seemingly dumbfounded. Zhang Miao then smiled to himself.
"Hehe, it looks like I've already subdued this guy. He won't come to his senses for a while. Seizing this opportunity, system, show me Black Zetsu's specialties."
"Yes, loading the specialties…" Upon hearing Zhang Miao's words, the system's voice immediately rang out.
With the sound of the system's voice, Black Zetsu's list of specialties appeared in front of Zhang Miao.
Option 1:
Kaguya's Will: Resurrect the Ten-Tails Jinchuriki with the Rinnegan as Kaguya.
Note: You can turn a male into a female, and you can turn a man into a woman. It's a remarkable technique. Would you like to try it?
Option 2:
Spirit Possession: Transform yourself into a dark shadow and attach yourself to another person. As long as you surpass them mentally, you can control the other person's body and make them act according to your will.
Note: Although it sounds a bit like possession by a ghost, in reality... well, it's pretty much the same.
Option 3:
Concealment: Those who possess this specialty can hide themselves in flowers, grass, trees, wood, and soil. Others will not notice them unless they actively reveal themselves.
Note: The pinnacle of spying, the number one in the ninja world. With this specialty, you are undoubtedly the king of espionage!
After reviewing Black Zetsu's three ninja specialties, Zhang Miao grimaced.
"Tch, all of these are useless junk!"
Although Zhang Miao said that with apparent indifference, his hands were not idle. Without hesitation, he selected the third option, and the system's voice followed.
"Ding! Congratulations to Your Holiness for obtaining the Concealment specialty. From now on, even if you're trying to sneak in somewhere, no one will notice you!"
Zhang Miao: "..."
Am I such an evil person?
I only chose this specialty to monitor my target. What does it have to do with sneaking in others' places? Besides, even if I wanted to, I could just transform and go in; there's no need for concealment.
With these thoughts, Zhang Miao mentally ridiculed the system and then looked at Black Zetsu, who was still in a dazed state, before coughing twice.
"Cough, cough..."
Upon hearing Zhang Miao's coughing, Black Zetsu immediately snapped out of it, looking at Zhang Miao with an unbelieving expression.
"Sir, is this..."
Seeing his astonished gaze, Zhang Miao grinned again, nodding as he spoke.
"Yes, this is my will. His existence is similar to yours. The difference is that you are Kaguya's will, and he is my consciousness!"
Saying this, Zhang Miao turned to the Black Zetsu he had recruited.
"Starting today, your name is Black Kage. Follow Black Zetsu. You must work together to resurrect Kaguya as soon as possible!"
Zhang Miao had Black Kage follow Black Zetsu not with the aim of hastening Kaguya's resurrection but to steadily collect Black Zetsu's Ninja Fragments. However, Black Zetsu wasn't aware of this and assumed Zhang Miao recruited Black Kage to help revive Kaguya, making him excited and grateful.
"Thank you, sir. With Black Kage's assistance, my plan will go much more smoothly. Having an ally like you is wonderful. Once we've revived her, I'll definitely tell her about your help!"
As Black Zetsu's words fell, the system's notification rang once again in Zhang Miao's mind.
"Ding! Congratulations to Your Holiness for obtaining 7-star Kage-level, Black Zetsu Ninja Fragments x10!"
Hearing this notification, Zhang Miao knew that Black Zetsu's gratitude was sincere, so he immediately smiled.
"Haha, then I'll look forward to that day. I'll be waiting for your good news. Off you go!"
"Yes!"
As soon as Zhang Miao finished speaking, Black Zetsu and Black Kage both answered in unison and disappeared into the ground.
Once they had both vanished, Zhang Miao grinned again.
"Hehe, now I have a stable source of 7-star Kage-level, fragments. As usual, let's start with a round of lottery. System, use all of Black Zetsu's remaining Ninja Fragments for the lottery!"
"Understood, my lord!"
