Fortress No. 14 of the Kingdom of Rain guards the southern gateway of this country.

Less than twenty kilometers south of this fortress is the country of Sichuan, which is separated from the two great powers of fire and wind. Therefore, it has extremely important strategic significance.

Sansho Hanzo couldn't worry about others, so he entrusted it to his youngest son, and Sansho Koga personally guarded it.

But he didn't know exactly what his youngest son was doing here. If he had some idea, it wouldn't be surprising——

Why are there always outsiders coming in and out here?

The first wave of people who came here were Itachi Uchiha and the two spies from the root.

They disguised themselves as rain ninjas and came here to steal an important experimental report, and they were about to succeed. For the two spies, there was only one "self-sacrifice" task left to solve.

The second wave of people who came here was Uchiha Shisui who discovered Uchiha Flame and many bloody ninja corpses in a laboratory in Amegakure Village.

He came here following Weasel's trail, and also to answer some questions.

The third wave was carrying someone in a dark oilcloth carriage. He had just arrived outside the gate of the fortress.

"Stop."

Wearing a bamboo hat and holding a spear in his hand, Yu Nin stretched out his hand and stopped the carriage with only one driver.

Just looking at the style of the carriage, it must have been driven out from here.

"Are you bringing the children?"

The gatekeeper, Yu Ren, came to the coachman's side, looked around and asked, "Why are you the only one?"

His companion walked to the back of the carriage and planned to inspect the "goods" inside.

"Today is really unlucky."

The coachman raised his head, revealing a face stained with blood and bruises, and said in a muffled voice: "We met a group of rebels. They stayed behind and asked me to bring the people back first."

If you look carefully, you will find that this is the leader of the settlement that Yiyong saved before.

He used to be a member of the Rain Ninja, so it was quite natural for him to say these words, and it was even more natural when he was injured, with a bit of blame and anger. Anyway, with such an unrecognizable face, the other party

It's possible to identify him as anyone.

The key is what's behind.

The rain ninja who walked to the back of the car lifted up the oilcloth, and four pairs of lifeless eyes looked at him in unison, startling him so much that he almost jumped up.

But if you take a closer look, you will see that these are just four children ranging from six to ten years old. The reason why they have similar eyes may be because they are all afraid.

Considering what they are about to face, they should indeed be afraid.

"It's really unlucky..."

Yu Ren put the oilcloth back angrily and shouted in front of him: "There are only four brats."

"The number is a bit small, but considering what you've been through, it's pretty good."

The rain nin in front did not forget to comfort the coachman, and then walked to the gate and said something into the doorway. The huge iron door creaked open.

"Take them to the small door to the south."

"knew."

The driver responded and drove the car forward slowly.

There were some Rain Ninjas in the fortress courtyard, but they had no interest in the carriage. They took one look at it and continued to do their own thing.

"Are you familiar with this place?"

A question came from the carriage, and it was none other than Yiyong, one of the "four" children.

Fortress No. 14 was the destination where the previous group of rain ninjas wanted to kidnap the homeless children and bring them there.

This information was not asked by Giyuu. He did not have any torture skills, and his social skills were extremely poor. The people who pried open the jounin's mouth were those angry vagrants who almost lost their lives and children and were oppressed by the rain ninja.

them.

What did those people do to Yu Ren? Yiyong only listened to a short paragraph before he didn't want to continue. Anyway, he got the information he wanted, and the homeless leader offered help.

According to the jounin, they kidnapped the children because they wanted to create a second ninja demigod through experiments. As for what kind of experiments, he was not a professional, so he didn't know the inside story. He only knew that the rain ninja kidnapped children from surrounding small countries and domestic countries.

There are many, but once you enter this building, very few come out.

Needless to say, just the word "experiment" successfully touched Yiyong's sensitive vocabulary.

He didn't forget how Zhisui explained to him "why Wen's body disappeared".

At least, Yiyong felt that the chance of finding Uchiha Flame in this place was much more reliable than searching for the so-called "angel", so he came up with this plan to go deep into the tiger's den and attack the yellow dragon.

"I used to work at Fortress No. 7 near the Fire Country."

The leader of the homeless took a deep breath and touched the wound on his face as he replied, "The layout of these castles are all similar, and I am quite familiar with them."

"This is dangerous."

"I know."

The homeless leader said, "But you have helped us, and we have nothing to thank you for. We can only do a little bit for you. I can tell that someone important to you is missing, right?"

Yiyong said nothing and quietly extracted chakra.

The other three "children" are all the results of his shadow clone + transformation technique.

Two minutes later, the carriage stopped at the dark south side of the fortress.

The homeless leader held up the Yugakure forehead protector and knocked on the door. The three transformed shadow clones all followed Giyuu out of the car in a daze and stood behind the homeless leader without saying a word. They were exactly the same.

expression.

【Is this transformation technique really useful? 】

The latter complained secretly in his heart.

"Has today's arrived too?"

The person who opened the door was a bald man, his eyes seemed to be squeezed through the crack of the door, only a little smaller.

Seeing that there were only four children, his flabby face simply dropped, "That's a lot."

Just when the leader of the homeless was about to explain, the man looked at his face and waved his hand, "Needless to say, I must have been attacked. I'm used to it. Four is four, it's better than nothing..."

Then, his eyes scanned the faces of the four volunteers one by one.

"What, these four children are one family?"

Otherwise, there is no such thing as a look.

All the volunteers nodded at the same time.

The bald man suddenly turned from worry to joy, "That's great, we can do a more detailed control group experiment..."

The homeless leader was speechless.

[Don’t you doubt such an obvious loophole? 】

The bald man leaned down, smiled broadly at the volunteers and said, "Come with me, I'm going to do some examinations for you. Those who pass the test can become ninjas and live in Yuyin Village. Doesn't this sound good?"

"What about the unqualified ones?"

Yiyong's body tilted his head.

"Those who are not qualified will stay here as servants, preparing food for Lord Koga's sansho fish."

The bald man still smiled gently, but Yiyong understood the true meaning of "preparing food".

As for the homeless leader, he suddenly felt a cold current rushing from his spine to the top of his head. His faint anger had been covered up by fear, and he just wanted to leave this place quickly.

"Okay, you go, I'll just take them there next."

With that said, the bald man was about to close the door, but was stopped by the homeless leader with the sole of his foot.

"that……"

He faced the suspicious gaze of the bald man and waved his hand to Yiyong who gave him a warning look.

"If you succeed in becoming a ninja, you must visit us."

Yiyong hesitated for a second or two, then nodded.

Only then did the door close, and the bald man returned to his smile, "Don't worry, just follow me. If you are lucky, you may still meet again."

All the volunteers exchanged glances with each other, but did not speak. They just followed this man, seemingly very obedient.

The two walked through the long corridor inside the fortress, went up to the second floor, and walked all the way to the deepest room. After opening the door, what greeted Yiyong's eyes were two rows of hospital beds with pulleys, and four people wearing white clothes.

A man in a doctor's coat.

Seven children of different ages were lying on the hospital bed, each of whom was wearing a ventilator. There was a monitor on the cabinet next to the bed, which showed the children's vital signs, but Yiyong couldn't understand it.

The men dressed as doctors all wore gas masks and were walking back and forth between the beds, transcribing the data on them.

In addition, there are fifteen empty beds in this room, but most of them have signs of being laid on and look like they have just been moved out.

While the bald man was talking to the "doctor", Yiyong's eyes stopped on one of the children, looking through his skin and bones and observing his respiratory tract.

Then he discovered that what the other party absorbed from the ventilator was not pure oxygen, but also mixed with some kind of thin lavender gas. Those gases had a strong paralysis effect, making the inhaler completely paralyzed, and would also
To be continued...
