As Sasuke With 10-Quest System

Sasuke threw the lifeless body of Sai on the ground. He didn't expect him to die since The Tongue Eradication Seal was told to only paralyze the ninja if he tried to give information about The Root or Danzo to others.

'Surely I didn't kill him by grabbing his neck too hard,' Sasuke thought as he decided to get rid of the body.

"Amaterasu" Sasuke casted Amaterasu and turned Sai's body to ash in less than a minute.

However, at this moment, Sasuke sensed two ninjas coming towards his location.

"Are they here for him?" Sasuke said as he scattered Sai's ashes around, so people didn't expect that there was a dead body there.

"Weird, I thought he was here," one of the ninjas said.

"Let's go, we can't let Danzo-sama wait" The other ninja said as they turned around and left.

Sasuke decided to follow them after hearing their conversation and soon reached the main entrance of The Root Headquarters.

"Where is he? He is the only one missing. Either way, come inside" A Root ninja who was guarding the entrance said as he let them inside.

"Let's see what Danzo is cooking" Sasuke said as he decided to secretly infiltrate the Root Headquarters.

...

Danzo was sitting on his chair in the hall as the entirety of The Root stood before him.

"From now on, refrain from going outside for the next two days. I need you all to be ready for what comes later" Danzo said as all the ninjas under him nodded.

Danzo was recently approached by the Akatsuki who offered to make him the next Hokage of The Hidden Leaf Village.

In return, they will get the Nine Tails. Danzo reluctantly agreed to their offer and provided them with information about everything regarding The Hidden Leaf Village.

Although he had betrayed The Leaf Village, he didn't want to work with Akatsuki, so he made a plan to betray them, too.

Danzo's idea was to kill the Akatsuki once they were tired of fighting the village and had already killed the current Hokage Tsunade.

After that, he will appear and save the village from the intruders which will make him a hero in people's minds.

That way, the village won't lose the Nine Tails and he will also become the next Hokage.

However, he had no idea that Sasuke had already infiltrated the base and was hearing everything. He was about to fuck everyone up.

*Boom*

A loud noise was heard as a giant round barrier surrounded everyone in the Root immediately.

"What the hell is that?"

"Enemy attack?"

"Shit"

All the ninjas had different reactions to the sudden change in terrain. The only one who had a calm mind among them was Danzo who slowly removed his gauntlet and the bandages on his arm.

'I shouldn't have trusted those weird orange hair ninjas, they have decided to attack me instead of The Leaf Village.

I should have killed them right there, but that's fine; those puny ninjas won't survive tonight," Danzo said as an arm made of Sharingan was revealed after he had removed the bandage.

"What the fuck is this fire?"

"HELP ME!!!!"

"Stay away from me!!!"

"That fire is similar to that Uchiha bastard"

Panicked spread in the barrier as the Root Ninjas tried to avoid the ever-spreading flames of Amaterasu.

'So Itachi is here too; I need to find an opening,' Danzo said as he stood up and revealed Shisui's right eye.

"Let's attack the barrier," Some ninjas said as they failed to break the barrier. In fact, the barrier itself was caught on fire when they tried to brute force it.

Some ninjas who had earth affinity and kekkei genkai tried to run away from below the ground but unfortunately, they rushed to their death since the barrier was of spherical shape.

Slowly, all the ninjas except Danzo burned to death.

Danzo on the other hand was slightly pissed because all of his tools were dead but he didn't mourn their death or anything.

They died for the village and the nest Hokage so their sacrifice will be worth it. So what if he doesn't have any underling? He could just cultivate more.

'How many of them are there? So far there isn't a single person in sight but there has to be two enemies. One is no doubt Itachi and the other should be a barrier master" Danzo said as he activated Izanagi and a sharingan eye on his arm slowly closed forever.

The barrier slowly disappeared after everyone's death and Danzo saw a figure walking towards him.

However, before he could see the culprit's face, he disappeared from his sight.

"What is this pain?" Danzo wondered as he looked towards the right and realized that his right arm was missing.

"What the? SASUKE!!!???!!!" Danzo yelled as he turned around and saw Sasuke grabbing his arm.

Although, he had never seen Sasuke after he left the village. He could easily recognize that face and the Sharingan.

'I need to use Kotoamatsukami on him' Danzo thought.

However, before he could use Kotoamatsukami on Sasuke, he disappeared from his sight and slashed his neck.

"Fuck" Danzo cursed as he decided to use Shisui's Mangekyo Sharingan to cast Izanagi and save himself.

He wanted to use Shisui's Kotoamatsukami on Sasuke but instead decided to save his own life.

Even if he could have used Kotoamatsukami on Sasuke and made him his tool, what is in there for him if he is dead already?

"What the hell?" Sasuke said as the Sharingan arm that he was holding disappeared and a completely healthy Danzo appeared in his sight.

"So you killed Itachi and took his eyes." Danzo said as he lost the light in his right eye which turned white.

"You can say that" Sasuke said as he used Amaterasu on Danzo yet again who used Izanagi on himself to save his life.

"I'm immortal. You can't kill me. Say your last words before I kill you," Danzo said as he tried to inflict fear on Sasuke, which made him laugh.

"Do you think I came here alone?" Sasuke said as he casted a genjutsu on Danzo which worked. He cast a genjutsu because he was afraid that Danzo might hide or run away.

Sasuke was confident that he could kill Danzo but he was a bit skeptical since he was in his enemy domain. He might have some teleportation device for emergency escape or some shit.

"Fuck, is the whole Akatsuki here?" Danzo said as he saw 6 figures hiding in the corners including someone with a sharingan.

Poor guy had no clue that it was all Sasuke's genjutsu.

'I need to hold Sasuke hostage so I can negotiate with them.' Danzo fell into Sasuke's trap and decided to fight him till the end instead of running away.
