As Kai woke up, he was once more teleported to the void-world, where all he could see was in front of him, a blue display that announced
'Welcome to the Dreamer Simulation...'
Kai gulped, he knew that unlike the others, he had no choice of what characters to pick, all he could hope for was a good character that can impact the story
*bzzt* 'You have picked... Sasuke Uchiha..'
*bzzt*, once more, an error display began to occur 'You.. have picked... the abilities of Madara Uchiha..'
....
Kai was surprised seeing this. Madara Uchiha is one of the more overpowered character in Naruto. Although he was nervous about the simulation, perhaps with Madara Uchiha's ability, things would be a lot easier.
However, before he could think of anything, he had started losing consciousness from the void world and entered the simulation world.
...
Kai started waking up from this, and he slowly looked around. He noticed that around him were forests. Which part is he on right now? This was just a forest and there was nothing else. Immediately afterwards, Kai's head began to hurt.
"What is this!? A mere child trying to control my power??" It was Madara, a consciousness that was so strong that this time, Kai could fully hear the consciousness instead of Itachi's faint emotions and feeling that are much receivable.
"Child, Where am I? I can't do anything, All I can do is... give some of my ability or talk to you."
Madara then stayed quiet for a bit. Then he immediately continued,
"Curses, what is this technique, I really can't break free."
Kai was very confused, and he really couldn't do anything. His body can barely move as this consciousness was fully opposing Kai. At this point, Shino arrived far earlier than was expected.
"Sasuke, you're still here?"
Kai was already struggling and his body was still frozen
"You don't look fine. You should fall back Sasuke."
Just as Shino was approaching Kai, Kai's body suddenly moved by itself. It was just a simple punch, however, it was delivered to Shino at the most critical point and there was no chance he could have avoided it. He tried to block it with his bug, but it was just too late for Shino.
Shino immediately passed out, and the consciousness once again said.
"Huh, I really tried to kill him. Child, your body is not strong enough.. But it seems like you are of the Uchiha blood.. my clan. At least that's the only thing acceptable."
Immediately afterwards, Kai resisted this consciousness and slowly attempted to regain control..
"Damn it... how is this consciousness so strong... It's way more than I expected"
Madara replied, "Hahaha.. Of course, how can a mere child fully control m..e..."
Madara immediately stayed silent as he focused his senses towards a direction.
"This Chakra...??" Madara said quietly..
"Boy, take me there. Now."
Kai refused. At the end of the day, the majority of the control is still in Kai's hand.
"No, you should listen... to me!" Kai said while still struggling.
Kai had now realised the situation. The fact that Shino was catching up to Sasuke, and along with Madara's agitation, he knew this scenario was Orochimaru's saga, the time when he attacked Konoha.
Madara started getting annoyed. "Ugh, I swear I'll kill you if you don't listen to me."
"If you could've done that, you'd do that already," Kai responded.
"I also know your agitation, Hashirama is in that direction isn't it?", Kai laughed at Madara.
Madara just stayed quiet, he's not one for big words and that was enough to leave him quiet.
However, his fighting spirit has really peaked due to his sensing of Hashirama's chakra. He became really agitated.
"Fine boy, if you let me have this battle, I'll let you use my ability afterwards for what you want to do!!! Think about it, all that power"
Kai thought about it for a while. To be honest, this did not seem like a horrible idea. At least letting Madara control his body will guarantee his survival knowing his immense ability. Yet on the other hand, Kai knew how shrewd Madara is, he might know some things that Kai did not know...
Right now, Kai could sense that although Madara could partially control the body if Kai showed a moment of weakness, he was still the main host and could quickly retain his body's control. It doesn't seem like such a bad idea...
