At the base of Konoha Root, a man shrouded in a black cloak came out of a secret room and walked quickly towards the place where the group was hiding with a sealed scroll.

What he has in his hands is information that is directly conveyed through secret arts. I took it directly to Tuanzang, because he told him to report it as soon as possible if there was an abnormality.

Written on the scroll is information about the four palaces of Yuzo.

After Yuzo left Konoha, the roots have been tracking by a master, trying to grasp all his whereabouts, at least some things before entering Akatsuki. This may not be of much use, but it may also make a huge difference. There are many similar intelligence work, but the main concern of Tuan Zang during this period is naturally our protagonist.

Tuan Zang is checking his arm, after all, it is not the original and always needs to be well maintained, and there are many things installed on it, which needs more attention.

By the time there was a knock on the door, he had already begun to re-wrap the bandage and install a huge metal restraint device to prevent the first generation of cells from going berserk out of control. After his arms were hidden in the wide sleeves of his coat, he said to his men who had been waiting outside for a long time:

"Come in."

"Lord Tuanzang, this is the latest information, marked as an emergency, about the four palaces of Yuzo." The person who came handed the scroll to Tuan Zang and said with his head down.

"Drop it, you're good to go."

Seeing his subordinates put down the scroll and turn around and go out, Tuan Zang picked up the sealed scroll, and after habitually checking the sealing technique, he opened it to see after confirming that no one had opened it.

"Loulan's business?" As he read, Danzo recalled some information about this place. But after all, it is a small place that is not famous, and it has been destroyed for many years. After the crystal brought back by the fourth generation was in his hands, he sent someone to investigate, but the so-called dragon vein was impossible to use, so it was gradually forgotten.

After many years, it was hard for him to think of anything more, after all, he was already old.

"The explosion of the seal of the four generations, the explosion that was supposed to destroy the entire Loulan ended hastily, and only destroyed a little place?" The scroll is written in more detail about the process of the incident, but the only thing that is enough to attract the attention of Tuan Zang is the explosion caused by Ma De's destruction of the four generations of seals.

After the explosion, Ma De disappeared, Sinomiya Yuzang was unscathed, and even some unknown changes appeared, which were written inside. Although the guy who was tracking Yuzang was very capable, it was impossible for him to get too close, and after the explosion was over, he was only treated as a broken bone and a slag left in Mader's body.

This is the only explanation.

And Yuzang was unscathed, and even suddenly changed his clothes, and some changes after the explosion, such as the loss of his ninja bag and other things, could not be explained.

Tuan Zang's thoughts were chaotic for a while, and there must be something wrong with this. But what's wrong?

Half an hour later, Danzang directly induced the self-destruction technique on the scroll, allowing it to burn into a small pile of ashes. Then he clapped his hands and beckoned one of his subordinates and said, "Come with me to the laboratory to have a look, and in addition, bring me the report that Sinomiya Yuzang sent back before."

"Yes!"

The so-called report is the way that Yuzo left him to contact him before he left Konoha. Every once in a while, Yuzo is obliged to report his situation to his side, and for now, for the time being, Yuzo will only send one back.

Walking through the gloomy underground passages, Danzo, armed with a short cane, carefully reads the report sent back by Yuzo. It's all nonsense, like passing through those places, what you did, and so on. Compared to the information conveyed by the tracker, it basically has no reference value.

Danzo tried to find some anomalies in it, but Yuzo's perfunctory report clearly didn't have any useful information.

With a sigh, Danzou decided not to think about it anymore, there was too little useful information to know what was wrong with it.

Through a heavily guarded sentry, Danzo arrived at the research base belonging to the Roots.

Except for Orochimaru, no one in Konoha has engaged in human experiments? Apparently not. There is also a group of ninjas who are also engaged in it, but they are not as unscrupulous as Orochimaru, and even attack their fellow ninjas in the same village. As the master of the roots, it was much easier for him to do such a thing than it was at Orochimaru's time.

Besides, many people speculate that the reason why Orochimaru embarked on the road of obsessive human experiments has something to do with Tuan Zang.

However, Danzang rarely attacks his own people. In other words, even if you attack your own people, there are basically no people who know about it, and they do it very secretly.

This experimental base is one of the base camps for human experiments in Tuanzang.

The person in charge of the experimental base came out to greet Tuanzang.

The person in charge knew Tuan Zang's style very well, so he didn't talk nonsense about anything inconsequential, and directly took Tuan Zang to the laboratory to observe the ongoing experiments.

In the laboratory, it is a scene where normal people will be nauseous and vomiting and have nightmares at night.

Rows of laboratory benches were full of people, some of them looked very normal, but some of them were very abnormal. One of them had turned into a corpse, white bones and internal organs of various colors exposed, all the skin had disappeared, and the bright red muscles and white tendons were clearly visible.

This is a normal kind, and some people are covered in foul-smelling abscesses, bleeding yellow-green juice, and he even keeps moaning faintly. Every time the dull pair of pupils reflected the figure of the busy experimenter, there was a hint of pleading.

There are also people who have various deformities and mutations, such as misaligned bones, chaotic growth of organs, and a few extra eyes and mouths.

In short, a hellish scene.

"Where's the test subject of the Thread Escape Cell?" Tuan Zang ignored all of this and asked directly about the purpose of this visit. No matter how superb these people's skills are, the results of the experiment are not satisfactory in the end, don't you see that everything on his body is provided by Orochimaru? Compared to geniuses, these people really can't satisfy Tuan Zang.

But after all, where to find someone with this kind of talent, Orochimaru Danzo originally wanted to cultivate it as his own men, who would have thought that he would be crooked...

It's a pity, Tuan Zang miscalculated the ambitions of a certain viper.

"Here, Lord Danzang, please come with me."

Danzou followed the person in charge of the lab to another lab, where there was only one test subject, tied to a platform. There are also various yin and yang scripts around the platform, which seem to be guarding against this "thing".

Something indeed.

The person in charge began to explain: "This cell has been cultured and implanted many times, and the final result is a pity, only this one test subject happened to succeed. However, this only means that he survived the rejection period, and the ability to make threads is obviously not available. Or even if it does, it won't be used. ”

"This test subject has become an idiot?" Danzang asked.

"No, idiots also make sounds, they eat, and they have all kinds of instincts. But this guy doesn't have any of these things at all, he doesn't even move on his own. Only breathing, like a living piece of meat, we can only inject it with some liquid nutrients to keep it alive. The person in charge said with some annoyance: "However, it has another special feature, that is, it will react to chakra."

"What's the reaction?" Hearing this, Tuan Zang was slightly interested.

"Well, how to put it, as soon as there is a chakra fluctuation around it, it will immediately become mobile, rushing up like a crazy thug and attacking the target by all means." The person in charge said: "For example, hand scratching, teeth biting and the like." And its strength and speed are amazing, compared to the physical skills of the upper ninja, it is not bad, and it has caused a lot of damage. ”

After a general understanding, Danzang asked, "Does it have chakra in it?"

"Nope." The person in charge shook his head.

"I see, and the rest of the experiment continues. It is important that new living individuals appear, and that they are wise! Tuan Zang ordered death.

"Yes!" The person in charge accepted the order without any rebuttal. He knew that if he dared to object, he might not survive for the next second.

Over the years, it is precisely because he understands Tuan Zang and has some talents that he has survived to this time.
