As Sasuke With 10-Quest System

[Host has received Eternal Mangekyo Sharingan]

The system alerted Sasuke as his eyes bled a little, and the pattern of his pupil changed from a 3-tomoe Sharingan to a star-shaped Mangekyo Sharingan.

[Your exclusive Eternal Mangekyo Sharingan abilities are Amaterasu and Kagutsuchi]

Sasuke heard the system's notifications and grabbed a piece of cloth to clean the blood on his face.

"Let's go and check Orochimaru's prized possessions," He said as he went towards a certain room.

While searching for Orochimaru's room, Sasuke found a weird place that had many experiment materials and some weird stuff.

The room looked like it was the main experiment lab or storage of Orochimaru.

"Maybe I can find Hashirama Cells," Sasuke said as he finally reached that room and entered it.

The things that he found inside were very disturbing. Different parts of bodies were hanging around. Some tubes had blood while some had eyeballs.

Despite the disturbing scenes around. Sasuke, with his E.M.S., saw a small cupboard that was hidden behind a bunch of skeletons.

He approached the area and opened the cupboard.

"Forbidden Jutsus?" He said as he saw a bunch of hidden and forbidden jutsus inside.

Living Corpse Reincarnation, Impure World Reincarnation, Cursed Tongue Eradication Seal, Multiple Shadow Clone Jutsu, Rasengan, Twin Snakes Mutual Death Technique, One's Own Life Reincarnation, Shinigami Control Technique, Corpse Clone Technique, Reaper Death Seal, Subordinate Seal, Hidden Lotus, Earth Grudge Fear, Cursed Seals Of Heaven And Earth, Life Control Seal, Exploding Shadow Clones, Slave Seal, Handless Casting, Self-cursing seal.

[Jutsus and techniques have been stored in the Memory Bank]

"I expected nothing less from Orochimaru. He really wanted to collect all the jutsus. Though I might only use Exploding Shadow Clones and Handless Casting," Sasuke said as he realized how dangerous Orochimaru truly was.

He lost to the Reaper Death Seal and ended up acquiring it. He lost both of his hands and somehow got Handless Casting so he can cast jutsus without hand signs.

"I don't think I could have killed a healthy Orochimaru. I was really lucky. Either way, everyone can relax now.

If he had time and health, he might have become the main villain and ended up becoming the jinchuruki of ten-tails." Sasuke said as he wondered if Orochimaru had some normal jutsus.

"Amaterasu," He said as he burned those forbidden jutsus. He already had them in his memory bank so he didn't need those.

After using Amaterasu, he tried to control it with Kagutsuchi so he could only burn the cupboard and not the whole room.

He didn't want to accidentally burn everything and remove the oxygen in the area. He would rather die on battlefield than to die from suffocation.

As for the weird body parts and DNAs, he stored all of them in his inventory. He opened his inventory and saw all the items in the inventory.

The dimensional space of the system could store 9999 items, so he still had a lot of space despite clearing out everything here.

He even stored the cards given by the system inside for safety because the inventory was only accessible to him. Also, the inventory could only hold non-living things inside.

After searching around for some time, he found fifty million Ryo in a room, which he stored inside the inventory for his future funds.

In the end, there was only one room left to explore. That room had a lot of papers, so it looked like an office. Inside the office, the first thing he found was a map that had the location of all of Orochimaru's bases.

"What the fuck? This guy was running an entire ninja village for Land of Sound which is made up of secret hideouts?" Sasuke couldn't believe what he saw after seeing the papers in the record room.

Apparently, he regularly received funding and missions from the Land of Sound. Orochimaru would send his minions to complete it for the country as the Kage of Hidden Sound Village.

Sasuke wondered what happened to the Sound Village after his death since the show never showed us. Either way, he put all the papers and files inside his inventory.

Once he had searched the entire base, he was satisfied.

"Unfortunately, no Hashirama Cells and no normal jutsus can be found here; maybe there are somewhere else." He said as he decided to leave.

Upon reaching the blocked entrance, Sasuke grabbed the instant mastery card from his inventory.

"System, use instant mastery card on Susanoo," Sasuke said

To others, it may look like it was a stupid idea to waste an instant mastery card on Susanoo, but to Sasuke, it was not.

He was sure that the original Sasuke survived against Deidara due to plot armor. He wasn't sure if the plot armor would help him or not since it was his reality from now on. Better be safe than sorry.

More importantly, if he used Susanoo against Deidara, Obito would definitely try to get rid of him. Sasuke just wanted to ensure his survival. If Obito as Tobi ends up fighting him, he will pull out Perfect Susanoo. If it can't kill Obito then it can definitely help him run away.

[Instant Mastery Card has been used on Susanoo]

[Congratulations, Host can now use Perfect Susanoo.]

[If Host has tailed beast chakra then he can combine it with Susanoo to reach Indra's Susanoo form]

"Let's see how powerful Susanoo really is". He said as he took a large and calm breath.

"Perfect Susanoo"

Sasuke said as a large behemoth of a creature appeared around him that had a height of more than 200 Meters.

The Perfect Susanoo tore through the boulders, and with its wings, it flew straight to the sky.

"Woah, I'm really flying," Sasuke said as he floated in the sky.

He took a brief look at his Susanoo and realized that his Susanoo had a sword and a crossbow. Overall, it looked majestic.

"I need to go down fast. The Chakra consumption is way too high". Sasuke said as he started to descend.

"I'm glad that it doesn't hurt much. It just tickles a little." Sasuke landed on the ground, which caused the ground to become a crater.

*Boom*

The land couldn't handle the might of Perfect Susanoo so the whole base got demolished instantly.

"Fuck, I hope that those people are all right," Sasuke said as he realized that there were still many victims of Orochimaru inside the base that he had imprisoned.

Sasuke disabled his Susanoo and went to see if there were still some people alive.

Unfortunately, all of them became meatpaste.

Due to being from Earth and a different person, he felt guilty for unnecessarily killing those innocent people, if there were any. However, he doesn't care if he kills his enemies or people who deserve to die.

"I feel a little regretful for killing those innocents. I will make sure it doesn't happen again and keep my power in control" He said as he decided to leave this place for good.
