My older sister is Kushina

Kaleidoscope Sharingan!

After confirming that the three-tomoe Sharingan could not penetrate the barrier, Uchiha Shisui quickly activated his Mangekyou Sharingan. The black tomoe in his blood-red pupils spun rapidly and then transformed into a special whirlwind shape, which was his Mangekyou Sharingan.

Previously, at the ninjutsu exchange meeting, Uchiha Shisui had already revealed his Mangekyou Sharingan, so now Captain Langya and Hyuga Hima have no need to hide anything.

With the Mangekyou Sharingan activated, his eye techniques have been significantly enhanced and improved compared to his previous three-tomoe form.

Soon, Uchiha Shisui showed a hint of disappointment.

He immediately deactivated his Mangekyou Sharingan and reported to Captain Langya, "Captain, even with the Mangekyou Sharingan activated, I still cannot penetrate that barrier."

Uzumaki Hanamichi nodded. He wasn't surprised, because he had already used his Mangekyou Sharingan to observe the barrier beforehand and found that it couldn't be penetrated.

In terms of Sharingan power, Uzumaki Hanamichi's Mangekyou Sharingan is no less powerful than Uchiha Shisui's. He had already awakened his Mangekyou Sharingan long ago and had undergone considerable training in eye power. Currently, his eye power level has reached a very high level, while Uchiha Shisui's Mangekyou Sharingan has not been awakened for very long.

Hyuga Mai exclaimed in surprise, "Neither the Byakugan nor the Sharingan can penetrate the barrier, Captain, what kind of place is this?"

Before this, Uzumaki Hanamichi only said that he was carrying out a surveillance mission, without mentioning what this place was. At this moment, Hinata Hima was very curious. She had never noticed this place before, and it even had a special barrier set up.

Uchiha Shisui looked at Captain Langya, who was also very curious about the target of this mission.

After thinking for a moment, Uzumaki Hanamichi did not hide anything: "This is the organization's secret prison."

Hyuga Hima's expression shifted slightly: "The Root organization actually operates a private prison?"

Uzumaki Hanamichi nodded: "Yes, this prison was established during the war and is still in operation. The reason we are monitoring this prison is because the Hokage noticed that it seems to be acting strangely lately."

Hyuga Hima: "I see."

Uzumaki Hanamichi: "I infiltrated a prison once before, but I didn't find anything special. Let me tell you about the inside of the prison first."

Uchiha Shisui and Hyuga Hima immediately nodded.

Uzumaki Hanamichi then gave Uchiha Shisui and Hyuga Himaru a detailed description. He had been monitoring the Root organization's prison for a period of time and was very familiar with the situation around the prison. This was Uchiha Shisui and Hyuga Himaru's first time here, so it was necessary to explain some details that needed attention.

Finally, Uzumaki Hanamichi said, "I have explained the details of the mission to you. For the next period of time, the three of us will take turns on duty. Remember not to act rashly, and report any special circumstances immediately."

Uchiha Shisui and Hyuga Hima both replied, "Understood, Captain!"

Today is the first day that Hyuga Himaru and Uchiha Shisui are on duty. Uzumaki Hanamichi is not in a hurry to leave, but instead follows the two to carry out their first duty and surveillance.

Under the cover of night, the three of them did not slacken their vigilance and kept a close watch on the Root organization's prison area.

The three were located in a very secluded spot outside the valley, quite far from the prison. However, Uchiha Shisui and Hyuga Himaru, who possessed special eye powers, were fine, as was Uzumaki Hanamichi. Of course, he did not reveal his Sharingan to Uchiha Shisui and Hyuga Himaru.

Before we knew it, it was midnight.

Whirlpool Flower City: "Alright, that's enough for today. I'll use my shadow clones to keep watch. Starting tomorrow, we'll take turns as we planned before."

Soon after, Uzumaki Hanamichi, Uchiha Shisui, and Hyuga Hima quietly left.

Whirlpool Flower Path left behind a shadow clone.

After entering the village, the three quickly separated.

Over the next few days, Uzumaki Hanamichi, along with Uchiha Shisui and Hyuga Hima, placed the Root organization's prison under strict surveillance, a level of oversight that was far more rigorous than the previous individual surveillance conducted by Uzumaki Hanamichi.

Around midnight that night, Uzumaki Hanamichi suddenly received an urgent message from Uchiha Shisui: there seemed to be something unusual happening in the Root organization's prison area.

After confirming the news, Uzumaki Hanamichi did not hesitate and immediately headed towards the valley in the direction of the Root organization's secret prison.

Soon, Uzumaki Hanamichi found Uchiha Shisui, who was secretly watching him.

Uzumaki Hanamichi approached Uchiha Shisui and asked, "Shisui, what's wrong?"

Uchiha Shisui immediately reported the situation to Captain Langya. About half an hour earlier, he had discovered a carriage quietly entering the Root organization's secret prison.

He immediately used his Sharingan to observe the situation of the carriage and found that it was carrying more than a dozen children. This situation was obviously abnormal. Although he had learned from the captain that the target of the surveillance was the secret prison of the Root organization, more than a dozen young children were too suspicious. Therefore, he immediately passed on the message to the captain, Wolf Fang.

Uchiha Shisui said, "Captain, the oldest of those children is only eleven or twelve years old. They are obviously not criminals."

Uzumaki Hanamichi nodded, having guessed a possibility in his mind. If he wasn't mistaken, it was probably similar to the human experiments at the secret base that had been destroyed before. The children, including Tamako, were the same as the children Uchiha Shisui had mentioned, but this time there were even more people involved. In addition, Orochimaru had been frequently entering this secret prison recently.

Of course, he cannot be 100% sure at the moment.

Soon, Uzumaki Hanamichi spoke up: "The specific situation is still unclear. We will continue to closely monitor this prison area."

Uchiha Shisui: "Yes, Captain!"

The next day, Uzumaki Hanamichi went to the Hokage's office early in the morning to report the situation to the Fourth Hokage, Namikaze Minato.

Minato Namikaze's first reaction was the same as Hanamichi Uzumaki's: "Could it be that Orochimaru and the organization are building a new experimental base in the secret prison?"

Whirlpool Flower Path: "That's possible."

Minato Namikaze: "We must investigate that thoroughly. You said you sent over a dozen children in last night, but there don't seem to be any missing persons cases in Konoha recently."

Uzumaki Hanamichi: "Konoha doesn't have it, but that doesn't mean other places don't."

Minato Namikaze: "Hmm, it seems the situation is getting more and more complicated. The organization's prison has a special barrier, making it very difficult to go in and investigate."

Uzumaki Hanamichi: "It's not particularly difficult, but if you sneak in, there will be a great risk if you are discovered. Last time, Orochimaru directly destroyed that experimental base."

Minato Namikaze took a deep breath: "So, what's the next step?"

Uzumaki Hanamichi: "I think we should observe for a while first. What we can be sure of now is that there are problems with that prison."

Minato Namikaze: "Well, then I'll have to keep working hard."
