"Senpai, what do you mean?" Shisui asked doubtfully.

Kakashi looks at Shisui and said: "Shisui, you should have opened your Mangekyō Sharingan right?"

Itachi looked at Shisui in shock. He can't believe that Shisui also has opened the legendary Mangekyō Sharingan.

Seeing that Kakashi knows about this, Shisui just scratches his hair embarrassedly and said, "Yeah, it was opened not long ago. How do you know Senpai?"

"Guess."

"Whaa..."

Kakashi's answer makes Shisui somewhat speechless. How can he guess something like this?

However, Kakashi really does just guessing. According to original work, Shisui should have opened the Mangekyō Sharingan at this time.

"Shisui, since you have both of your eyes, with Mangekyō Sharingan, you should be able to use Susanoo."

Shishui was startled. He didn't expect Kakashi to even know about this.

"Yes, Senpai, how did you know about these things?"

"Well, I also have Mangekyō Sharingan, so it shouldn't be strange for me to know about these things, right?" Kakashi said with a smile.

Shisui is stunned. Kakashi indeed have opened Mangekyō Sharingan earlier than him, so it was not surprising that he knew about Susanoo.

"Shisui, if I am not mistaken, we might need Susanoo to take this Sword of Totsuka. Try it."

This Sword of Totsuka is spiritual item and not a physical one, so Kakashi came up with conclusion after remembering the future event.

If his guess is correct, this method should work.

Hearing this, Shisui did not think much about it. After all, it is a pleasant thing to be able to collect an artifact.

Shisui closed his eyes slightly and immediately opened his eyes!

Mangekyō Sharingan!

The black four-corner darts pattern circulates in both of Shisui's eyes.

"Shishui, you don't need to use the full body of Susano, just make an arm."

Using Susanoo is making the eyes blinded faster, so it is better if Shisui didn't make the full body of the Susanoo.

If it's just an arm, there shouldn't be any major losses.

Shisui nodded, expressing his understanding.

"Itachi, retreat with me, what happens next may surprise you."

Kakashi finished speaking, and then pulls Itachi for more than five meters.

Itachi looked at Shisui's eyes, and there is a strange pattern that he had never seen before.

Shisui looked at the Sword of Totsuka not far away intently, his eyes widened, and a huge green skeleton appeared around Shisui's body.

"This is!"

Itachi was surprised, the scene before him was too shocking for the young Itachi.

"That is Susanoo, the ultimate skill that can only be used by having both of the Mangekyō Sharingan."

Kakashi said quite enviously.

Even if Kakashi have opened the Mangekyō Sharingan, with only one Mangekyō, he maybe won't be able to use the Susanoo.

Blood begins dripping from Shisui's eyes. Seeing this, Kakashi immediately said: "Shisui, quickly take it, otherwise, it will put a lot of load on your eyes."

Shisui nodded, as he understood the situation and gaze at the Sword of Totsuka.

Then the right arm of the green skeleton directly grabs the Sword of Totsuka!

But when Susanoo's right arm grabs the Sword of Totsuka, the Sword of Totsuka did not turn into a cloud of red mist like before, but it didn't change and was directly held tightly.

It's a success!

Shisui is overjoyed and he quickly stops the Susanoo.

Mangekyō Sharingan faded, Shisui felt a sharp pain in his body, and at the same time his body became soft.

Seeing Shisui's condition is bad, Kakashi hurried over to hold on to Shishui.

"Shisui, how are you?"

"It's okay, but I didn't expect that it would consume so much Chakra to use the Susanoo. This is the first time I use this Ninjutsu."

"Good, it seems that this Sword of Totsuka is fated for you." Kakashi said with a smile.

"Thanks to Senpai, I can get this Sword of Totsuka. But if Senpai is able to use this Sword of Totsuka in the future, I will give it to Senpai," Shisui said.

Kakashi waved his hand and said, "No, this is what you deserve."

Shisui wanted to say something, but the stone tablet suddenly began to crack at this time.

There is also an earthquake at this place.

Kakashi exclaimed: "Not good, this place is going to collapse, let's go!"

When Shisui and Itachi heard this, their expressions tensed. After all, if this place collapses, they will die.

Without saying a word, Kakashi directly picked up Shisui on his back and said, "Itachi, go!"

Itachi nodded, then chakra surging under his feet, and he ran in the direction from where they came from.

Kakashi follow closely from behind, even if he was carrying Shisui on his back, his speed was not slow at all.

Along the way, the flying stones splattered around but Kakashi dodges it one by one.

Shisui didn't say anything about putting him down. After all, he is not able to run as fast as Kakashi right now.

Shisui knows that no matter whether it is Kakashi or Itachi, they would never leave him alone.

After so many years of getting along with each other, Shisui knew exactly what kind of person the other party was.

What the three of them didn't notice was that a red light entered Itachi's mind at an extremely fast speed.

Itachi only felt that there seemed to be something else inside his head, but it was obviously not the time to care about these things.

The three rushed all the way, and finally saw the water where they came.

With three plops, all three of them jumped into the middle of the water pool.

Shisui's body also temporarily recovered his mobility, and with Kakashi's help, he left this place.

And shortly after the three of them jumped into the water, the place completely collapsed!

Boom!

The rubble then drops into the water making splashes all around.

Outside the place, Kakashi, Shisui, and Itachi jumped out of the lake.

"Hah, it's really dangerous, we're almost buried inside."

Kakashi said as he suddenly remembered Obito. At that time, he was buried on the ground, and then he starts to get into the dark side.

"It's too dangerous." Shisui also let out a long sigh of relief, as he is lying on the floor.

The first time he used Susanoo, it let Shisui knew about how much damage this skill would do to his body.

Kakashi estimates that Susanoo can only be used after having the Eternal Mangekyō Sharingan so there is no damage to the user's body. In the original work, Itachi's body condition is so bad. It is probably because of the use of Susanoo.

This skill is strong, but the load on the user's body is too heavy.

And using this Ninjutsu will speed up the blindness of the user's eyes.

In the original work, Sasuke was almost blind after using Susanoo for a few times. It can be seen how much faster the blindness happened by using the Susanoo.

At this time, Itachi was holding his head, there seemed to be something floating in his mind, but he could not see clearly.

He only knows that it is a piece of information.

Itachi closed his eyes tightly, trying to see the fog in his mind.

Kakashi and Shishui soon discovered the abnormal condition of Itachi.

"Itachi? What's wrong with you?" Shisui asked with concern.

Itachi shook his head and said, "It's nothing, I just feel like there is something inside my mind."

"It's okay, it should be an illusion."

"Yeah."

Itachi nodded as he can only think of that now.

"Well, let's get out of here, with such a big movement, it will attracts other people," Kakashi said.

"Yes, Senpai."

Just when the three of them were about to leave, three big words flashed through their minds.

"Yata Mirror!
