My older sister is Kushina

Whirlpool Flower Path and Inuzuka He walked down the stone steps for dozens of meters.

There are several hidden doors on both sides of the stone staircase passage that is tens of meters long.

Neither Hanamichi nor Inuzuka Kazusa touched the hidden door. Based on Inuzuka Kazusa's scent, Tamako's scent came directly from the area below the stone steps.

The two quickly reached the bottom of the stone steps.

What comes into view of the swirling flower path is a dark corridor with a heavy iron gate.

There was no one guarding the iron gate.

Perhaps the masked man who was just killed by Uzumaki Hanamichi was the one on guard duty.

Uzumaki Hanamichi and Inuzuka He quickly and quietly approached the iron gate.

Inuzuka He sniffed at the iron gate and said, "The target should be inside."

Whirlpool Flower Path nodded and glanced at the iron gate.

The iron gate was locked.

He could force it open, but it would likely cause quite a commotion. Thinking of the masked man who had just been killed, he said to Inuzuka He, "See if that man has a key."

Inuzuka He nodded and quickly returned: "Captain, I got the key."

He was holding a bunch of keys in his hand at that moment.

Whirlpool Flower Path got the key and tried it out, quickly opening the iron gate.

Behind the iron gate, on both sides of the corridor, are rows of stone chambers.

To be precise, they were individual prison cells.

Whirlpool Flower Path glanced around; some of the cells were empty, while others held people.

Inuzuka He pointed to a cell not far away, guided by the scent: "It should be that one."

Uzumaki Hanamichi's expression shifted, and he immediately walked towards the cell that Inuzuka He pointed to. Soon he saw several small figures.

Several children were being held in the cell.

Whirlpool Flower Path quickly spotted Little Jade.

The children appeared to have been drugged, and were all in a drowsy state.

Xiaoyuzi was curled up in the corner.

Seeing Xiaoyuzi's figure, Uzumaki Hanamichi finally felt a little relieved.

He then took out his key and tried it out, quickly opening the door to the cell in front of him.

Whirlpool Flower Path immediately entered the cell, quickly walked to Xiaoyuzi, checked her over, and confirmed that Xiaoyuzi was just unconscious.

Soon, he scooped Xiaoyuzi into his arms.

Inuzuka He asked with some confusion, "Captain, what kind of place is this? I've looked at the other cells, and most of them are filled with children."

Uzumaki Hanamichi looked at Inuzuka: "There are ninjas guarding this place, so it's obviously not an ordinary place. He, you take her away from here and go back to the village. Report the situation here to the Fourth Hokage and ask for support."

Inuzuka He immediately asked, "And what about you, Captain?"

Uzumaki Hanamichi: "I'll stay here to keep an eye on things and find out the details."

At this moment, he still had some guesses about this secret underground room. If he wasn't mistaken, it should be a special base, which probably contained a considerable secret. He had two purposes in sending Inuzuka He back to the village: one was to send Tamako back to the village and ensure her safety, and the other was to seek the village's support in order to better search for the secret base.

Inuzuka He hesitated for a moment, then quickly nodded.

Uzumaki Hanamichi and Inuzuka He quickly left the cell area.

Soon, the two returned to the stone hall and then left the stone cave.

Upon reaching the outside of the cave, Uzumaki Hanamichi handed the little tama in his arms to Inuzuka He.

Afterwards, Inuzuka He carefully retreated to the central area with Tamako and the ninja dog Kuroga, and then left the island.

Uzumaki Hanamichi confirmed that Inuzuka He had left the island and quickly returned to the cave area.

The people in the densely packed cave base don't seem to have experienced anything unusual yet. In the previous prison cell area, Uzumaki Hanamichi only took Tamako away. After all, the number of people is limited, and it seems that they will need to wait for support from Konoha to rescue them.

Whirlpool Flower Path first observed secretly for a while, and seeing that there was nothing wrong, he quickly went back into the stone hall.

There are five stone doors inside the stone hall.

Whirlpool Flower Path quickly slipped through the stone door leading to the cell. He already knew the mechanism of this door; he didn't dare try the other doors to avoid alerting the base. Now he felt...

The best course of action is to delay as much as possible and wait for support from the fourth generation.

Although tracking this secret base took a considerable amount of time, it wasn't too far from Konoha Village. If Jonin Inuzuka returned to the village at his speed, he should be able to receive Konoha's support before dawn.

Before waiting for reinforcements, Uzumaki Hanamichi had his own plans. At the moment, he knew almost nothing about the secret base, so he planned to investigate first.

This base not only secretly imprisons many people, but it is also guarded by ninjas, so it must be hiding some unknown secret.

There were several hidden doors in the stone staircase leading to the cell. He planned to check if these doors connected to other areas and then familiarize himself with the underground secret base.

After entering the stone gate, Whirlpool Flower Path quickly arrived at a hidden door. After studying it for a while, he soon found a way to open the hidden door.

Behind the hidden door was a dark passage.

Whirlpool Flower Path quickly entered the dark passage and moved cautiously.

The dark passage was nearly tens of meters long, and soon we reached the exit.

The exit was an open area, where a masked man was on duty.

The masked men on duty patrolled back and forth.

Whirlpool Flower Path remained calm and walked out confidently when the masked guard approached.

At this moment, he has transformed into the masked man who previously guarded the prison cell.

The masked man was initially surprised to see Uzumaki Hanamichi, but quickly relaxed: "What brings you here?"

When the swirling flower path reached the masked man, it suddenly launched an attack.

Before the masked man could react, he was killed instantly by Uzumaki Hanamichi.

Immediately afterwards, Uzumaki Hanamichi hid the masked man in a corner, removed his mask, and replaced it with his own.

Soon, Whirlpool Flower Path emerged slowly from the dark corner.

At this moment, he is a masked patrolman.

Walking at a leisurely pace along the swirling flower path, one can see stone chambers on both sides of the plaza.

Soon, a hint of surprise appeared in his eyes.

There are more than a dozen stone chambers, most of which are inhabited, or more precisely, people with tubes inserted into their bodies. Some people are even placed in sealed glass containers, their bodies soaked in an unknown liquid.

"Human experimentation?!"

Whirlpool Flower Path did not enter the chambers to examine them closely, as they were all locked. However, based on what he saw, he quickly made a general judgment: these stone chambers were laboratories, and the subjects of the experiments were human bodies, most of whom were children.

Thinking of the previous missing persons cases, the experimental subjects in this secret base, and the children being imprisoned, Uzumaki Hanamichi quickly guessed a possibility: many of those missing children were probably sent to this secret experimental base for human experimentation.
