Family Heirloom

With a series of tremors, Sasuke suddenly discovered a hidden door opening on his right, seemingly leading to an unknown place.

After discovering this, Sasuke hesitated for a moment before jumping down from the stone and entering the hidden door.

As he stepped inside, it was pitch black. While walking, Sasuke suddenly felt the steps he had just trodden upon begin to move.

Immediately, rays of light emerged, and torches on both sides of the stairs lit up, stinging Sasuke's eyes!

"How strange!"

Rubbing his eyes, Sasuke put away the lamp in his hand. After adapting to the surroundings, he walked slowly along the stairs.

About five minutes later, Sasuke arrived at an altar. On the altar sat three pairs of Three-Tomoe Sharingan preserved in test tubes, along with a scroll.

Beneath the altar was a stone coffin. Opening it, a corpse came into Sasuke's view: short black hair, empty eye sockets, looking to be in his teens!

"Uchiha Shisui?"

Looking at the person in the stone coffin, Sasuke's gaze was stunned. No wonder Yakushi Kabuto couldn't use Impure World Reincarnation on Uchiha Shisui; this place must be accessible only to the Uchiha clan head, as the location was far too secret!

"Rest in peace!"

Upon confirming the body was Uchiha Shisui, Sasuke unhesitatingly activated the God Refining System. After all, if it weren't for his Sharingan, that dog Danzo wouldn't have been so desperate for the power of the eyes.

After the God Refining process, Uchiha Shisui's body completely vanished from the stone coffin; such was the terror of the God Refining System.

"That feels a bit evil! But at least this way you won't be used for Impure World Reincarnation! I really am a good person!" Watching Shisui turn to dust, Sasuke hesitated for a moment before finding a casual excuse for himself!

Bypassing the stone coffin, Sasuke first activated God Refining on the three pairs of Three-Tomoe Sharingan. Once they were stored away, he turned his attention to the scroll on the altar.

After opening the scroll, Sasuke's expression froze. This was a scroll left behind by Uchiha Madara, primarily detailing how to cultivate Susanoo and how to evolve the Mangekyō into the Eternal Mangekyō.

"What is this? In the end, the thing I expected the most is the most useless!" Looking at the scroll, Sasuke shook his head helplessly, kowtowed a few times at the altar, and then left.

Returning to the previous basement, Sasuke closed the hidden door and left Naka Shrine. After all, it was already night, and it was time to head back.

He still had to go to the Ninja Academy tomorrow! Even if he was just sending a Shadow Clone!

Back at his home, Sasuke dispelled his Shadow Clone and went to sleep.

The next morning, after sending his special Shadow Clone to the Ninja Academy, Sasuke entered the basement and opened his storage grid, ready to check his haul.

The first things that caught his eye were the two extra Uchiha bloodline crystals. Sasuke wasn't surprised by this, but the next few items left him stunned.

[Six Paths Yin Power: After use, it can evolve the Mangekyō Sharingan into the Sage's Eye. The evolution time depends on the level of the Mangekyō Sharingan!]

[Six Paths Yang Power: After use, it can evolve the Advanced Sage Body into the Sage Body. Requires a certain amount of time!]

The first two items caught Sasuke off guard. As expected of the stone tablet left behind by the Sage of Six Paths! The items refined from it were truly different!

"The time depends on the Mangekyō level, so I'll have to calculate this carefully!" Looking at the description of the Six Paths Yin Power, Sasuke began to plan.

"Uchiha Itachi, Uchiha Shisui, Uchiha Obito, plus my own and my father's—that's five pairs of Mangekyō. If I collect them all, the evolution time shouldn't take a lifetime like it did for Uchiha Madara, right?"

Subconsciously touching his eyes, Sasuke muttered to himself, then shook his head helplessly. He didn't even have his own Mangekyō yet, so he shouldn't think about such unrealistic things.

As for the Six Paths Yang Power, it could evolve the Advanced Sage Body into the Sage Body. In other words, it was essentially evolving the Asura bloodline!

After all, the Sage Body only appeared in the Senju and Uzumaki clans. Only by fusing the bloodlines of these two clans and the cells of Senju Hashirama and Uzumaki Naruto could one obtain the Asura bloodline, which was the Advanced Sage Body.

"Indra, Asura—what a pair of good brothers they were!" Looking at the descriptions of the Six Paths Yin and Yang Powers, Sasuke curled his lip helplessly and looked at the next item.

[Body Flicker Technique: A-rank; Uchiha Shisui's unique Body Flicker Technique!]

Seeing this description, Sasuke was a bit confused, but he quickly realized that since he hadn't killed Shisui himself, getting these items was already a bonus, especially since the old man's eyes had been split between Danzo and Itachi!

After looking at these three items, Sasuke felt something was off. Upon closer inspection, he realized the three pairs of Sharingan were missing!

Checking the items in his storage grid one by one, he found that his mother Uchiha Mikoto's Three-Tomoe Sharingan seemed to be undergoing a strange change.

[Three-Tomoe Sharingan: Evolving...]

Looking at this, Sasuke didn't know what to say. Could the God Refining System actually create a sixth pair of Mangekyō Sharingan for him?

"Whatever! I'll just absorb it at the end!" Looking at the description of the Three-Tomoe, Sasuke shook his head helplessly and took out the Kusanagi Sword he had kept with the clan history, activating God Refining.

After the process, Sasuke looked at the item in his storage grid and fell into deep thought.

[Ame-no-Murakumo-no-Tsurugi: Divine Artifact, Indra's sword, can be fused]

Seeing this, Sasuke was caught off guard. I knew it was impossible for a common Kusanagi Sword to be placed next to the clan history!

Facing this fuseable Ame-no-Murakumo-no-Tsurugi, Sasuke didn't have any immediate plans—or rather, he didn't want to use it yet. He wanted to equip the sword onto his Susanoo!

After all, when watching the anime, Sasuke felt the three divine artifacts of Uchiha Itachi's Susanoo were quite powerful. Furthermore, Sasuke didn't really want to use a sword himself; as for the reason, he wasn't quite sure, he just didn't like it!

Looking at the items in his storage grid, Sasuke thought for a while and closed the interface. These items were far too tempting; he felt that if he kept looking, he might lose control and fuse them immediately.

"Such a rich foundation! There's a reason for the saying that a starving camel is still bigger than a horse!" Watching his Shadow Clone still training, Sasuke sighed with emotion.

The Six Paths power is truly a bargain; a starving camel is indeed bigger than a horse.
