As soon as he walked into the Loulan ruins, Hinata felt a sense of depression.

This repression is not manifested in the chakra, but in the heart, like the feeling of an ordinary person who has strayed into the hunting area of a beast.

"Roll your eyes, open!"

With a low snort, Hinata opened her eyes and walked towards the central tower of the Loulan Ruins, carefully watching her surroundings.

In his white vision, everything around him was full of dead silence, and there was no sign of life activity in the entire Loulan Ancient City Ruins, let alone Chakra reaction.

"Hey, that's a little weird."

Seeing this scene, a trace of doubt suddenly surged in Hinata's heart.

Even if there are few creatures in the desert, there are still a lot of creatures such as snakes, insects, rats and ants, and it stands to reason that there are so many buildings left in the ruins of the ancient city of Loulan, which is a good place to shelter from the wind and sand, and there should be no signs of life activities at all.

Although he had doubts, Hinata was not the slightest timid.

No matter what was wrong here, it wouldn't be too much of a threat to him now, after all, even if the worst happened and the Dragon Vein Chakra went violent, he was sure that he would retreat.

It didn't take long for the Hyuga mirror to come to the place where the four generations sealed the dragon vein.

"Sure enough, it's a composite sealing technique!"

With just a glance, the Hyuga Mirror could discern that the sealing technique imposed on the dragon vein by the four generations was a composite sealing technique that used a mixture of various sealing techniques.

As he approached, he crouched down and carefully discerned each sealing technique.

As he analyzed, he muttered to himself, "The foundation should still be the Four Elephant Seal, which is also mixed with the sealing technique of the contract seal, as well as another sealing technique..."

After a cursory analysis, Hyuga Mirror could conclude that this dragon vein seal of the fourth generation had at least three powerful sealing techniques, and he had only recognized the four elephant seals and contract seals among them.

As for the third type of sealing technique, the Hyuga mirror did not have a clue, and it did not seem to be a sealing technique of the vortex.

"At that time, the fourth generation should not have inherited the position of Hokage, so there were only two ways for him to learn the sealing technique, one was to learn the sealing technique of the Uzumaki One Vein from his wife Kushina, and the other was to learn the sealing technique of the Miaomu Mountain One Vein from his teacher Jiraiya."

Thinking of this, Hinata Mirror had a guess.

The third sealing technique in this dragon vein seal, nine times out of ten, is the sealing technique of the first vein of Miaomu Mountain.

Getting up and taking a few steps back, Hyuga Mirror supported his cheek with one hand, pondered for a while, and felt that with his sealing skills, he was still somewhat sure of breaking through the dragon vein seal of the fourth generation.

After all, the entire dragon vein seal is based on the Four Elephant Seal, and the Four Elephant Seal is precisely the sealing technique he has eaten the most, so if it is forcibly lifted, it is not without a chance.

It's just that the dragon vein seal of the fourth generation contains part of the contract seal, which proves from the side that there is a certain contractual relationship between the bloodline of Queen Loulan and the dragon vein.

Therefore, if you want to be safe, when breaking the seal of the dragon vein of the four generations, it is best to bring the bloodline of Queen Loulan with you, so as not to make it difficult to submit after the dragon vein chakra runs away.

"But where can I find the descendants of Queen Loulan?"

Konoha Village, Root Base.

Swish...

A figure fell, half-knelt in front of Tuan Zang, and reported, "Lord Tuan Zang, we have finished examining Ding You's body. ”

Tuanzang, who was on a cane, slammed the ground with a cane: "Say the result!" ”

The half-kneeling member of the root immediately replied: "There are a total of thirty-seven wounds on Ding You's body, and the fatal wound is in the head, because the brain tissue is completely damaged, we can't find any information. ”

The more Tuan Zang listened, the more gloomy his face became.

When he learned the news of Ding You's killing, his first reaction was that this must have been done by Hinata, but after thinking about it for a while, he was not so convinced.

Because in his heart, Ding You's strength should be above the Hyuga Mirror.

What's more, Ding You has also carried out many assassination missions, including many assassination targets at the upper ninja level, whether it is strength or experience, Ding You is ranked first in the roots.

So even if Ding You is defeated by the Hyuga Mirror, he will not be able to pass on even a little news, and he will die inexplicably.

At this time, the Root member continued: "At the time of the autopsy, we also found a small amount of iron sand in Ding You's body. ”

Tuan Zang's eyes lit up: "Iron sand!?" ”

"Yes, those iron sand are very fine, uniform in size, and the chakra conductivity is very good, it seems to have been under the temperature of the chakra for a long time, as if..."

The root ninja was tempted to tell his guess, but he felt that his guess was too ridiculous to know how to report it.

Danzang has been in charge of the village's external spies for a long time, and his knowledge is one of the best in the entire Konoha area, so he doesn't need the root ninja to say it, he has already guessed what the root ninja wants to say.

"Sha Yin...", Tuan Zang suddenly asked, "The Zhongnin who sent Ding You's body back to the village, have you checked?" ”

The root ninja replied, "Yes, there is no problem with his resume, and it has nothing to do with the Hyuga clan. ”

Tuan Zang said sharply: "Search his brain, I want to know everything!" ”

The root ninja was stunned when he heard this, and whispered: "Lord Tuanzang, let's do this, three generations there..."

Forcibly searching the brain, there is a lot of hidden danger, and if you are not careful, it will cause irreversible damage to the ninja's brain, so this cruel torture method is often only used against the captives of the enemy village and the defecting reninciation.

Tuan Zang waved his hand impatiently: "Do as I say!" ”

"Yes!"

The ninja had no choice but to answer, and then quietly retreated.

Not long after, the root ninja returned again and reported to Danzou, "Lord Danzo, we have tortured it, and that middle ninja really has nothing to do with the Hyuga Mirror. ”

Danzo asked, "When Hinata handed over Ding You's body to him, was there any injuries on his body?" ”

The root ninja shook his head and said, "No, in the memory screen of that middle ninja, there is no injury on the Hyuga mirror. ”

Danzou then asked, "Where did the Hyuga mirror go?" ”

"He doesn't know either."

Tuan Zang secretly wondered: "Is it the Hyuga Mirror who killed Ding You, or the bounty ninja who stared at the Hyuga Mirror?" ”

At this time, the root ninja said weakly: "Lord Danzang, during the torture, we missed for a while, and damaged part of the brain tissue of the middle ninja, and he may not be able to continue to be a ninja in the future." ”

Tuan Zang said indifferently: "Just dispose of it." ”

"But..."

This root ninja naturally understands the meaning of the word 'dispose of', and he has done a lot of this kind of thing, but it was the first time he had dealt with enemies and traitors before.

Looking at the ninja in front of him who had not long joined the roots, Danzo said coldly: "Don't let the old man repeat it twice!" ”

The root ninja wiped the cold sweat from his forehead and nodded, "Yes!" ”
