In the previous perception of Uchiha Yuan, the dragon vein was a special chakra.

An Lushan used the power of the dragon vein to achieve a quick repair effect, and the Uchiha wanted to know if it was the power of the dragon vein itself that could be quickly repaired, or if An Lushan used special means to achieve this effect.

This shadow clone of Uchiha Hara took away most of the chakra of his body, and Uchiha Hara's idea was that if the collection of dragon vein energy went well, he would let the shadow clone send the chakra back to Konoha.

If it doesn't go well, then you have to do it.

As a result, the collection of the dragon vein chakra was unexpectedly smooth, after An Lushan's death, these puppets lost their ability to move, and the shadow clone of Uchiha Yuan easily collected the remaining dragon vein energy in Loulan's half of the puppets, sealed it in the sealing scroll, and then rushed towards the territory of the Fire Country.

Bo Feng Shuimen and his entourage, after returning to Konoha with the Flying Thunder God Technique, went to the three generations of Hokage to report the situation as soon as possible.

Although everyone's memories have been sealed, the dragon vein has also been sealed, and there is no doubt that the matter is perfectly resolved.

After the three generations of Hokage learned that the matter was resolved, they nodded with satisfaction, and then turned to Uchiha Yuan and said, "You guys have worked hard this time, let's go back and rest for a few days first!" After the end of the Shinobi exam, I will assign you a new task. ”

"Thank you, Hokage-sama." Everyone said in unison.

Coming out of the Hokage Building, Uchiha contacted Hinata Ayana and Yamanaka Tetsuki, and the three of them hadn't seen each other since they returned to the village!

Ten minutes later, the Uchiha Ena team assembled at the door of Ichiraku Ramen.

"Tsk, Asana, why did you become this good girl when you returned to the village?" Kazuki Yamanaka said as he looked at the well-dressed Hinata.

"The rules of the Hyuga clan are like this, I can't help it, is your mission going well this time?" Hinata Ayana turned her head to Uchiha and asked.

"I don't know, our mission experience has been sealed, but ......"

"But what?"

"It's okay, Ayana and I may need your help to do some experiments later, are you free over there? Can you leave from the Hyuga clan? Uchiha asked.

"It should be possible, now the people of the sect family will not control me because of the face of Hokage-sama and Orochimaru-sensei."

"That's good, I'll get back to you if I need your help."

Before I knew it, a week had passed, and the middle ninja exam had reached the final stage of the battle stage.

It is worth mentioning that two days ago, when Uchiha was far away from cultivating, he used the Sharingan and triggered the back door he left behind, recovering his memory.

And that very afternoon, the shadow clone of Uchiha Yuan also returned with the sealing scroll.

After the shadow clone is lifted, the memory will return to the main body, and Uchiha Yuan knew from the memory of the shadow clone that the amount of dragon vein chakra in this scroll is really quite a lot, almost two to three times that of the average shadow.

Uchiha Yuan opened the sealing scroll and extracted a small clump of dragon vein chakra, and as previously observed, the power of the dragon vein did contain a special chakra.

Immediately afterwards, the Uchiha went to the Death Forest, and because of this middle ninja exam, many birds and beasts in the Death Forest were injured.

The Uchiha collected the injured birds and beasts, and then the Uchiha tried to inject the dragon vein chakra into the body of a dying bird.

After absorbing the dragon vein chakra, Asuka's injuries gradually healed, but his mental state was still half-dead.

Uchiha Yuan felt a little strange, obviously his injuries had recovered, why didn't his life activities recover?

The Uchiha took out a cloud of dragon vein chakra from the scroll and continued to inject it into the body of another injured animal, and then opened the chakra eye to see how the dragon vein chakra flowed in the animal's body.

With the help of the Sharingan, Uchiha discovered that the dragon chakra had been circulating in the animal's body, but the animal showed no signs of regaining its vital activities.

After that, Uchiha Yuan called Hinata Aana, and together with Hinata, he experimented with the effect of dragon vein chakra on various animals, and the results were the same as the previous two times.

It turns out that the Dragon Vein Chakra does have a quick repair effect as Uchiha Yuan thought, but this quick repair can only affect the body, but it has no effect on the consciousness.

To put it simply, the animals have been saved, but they have all entered a state of suspended animation, and in this case, they are replaced by humans, that is, vegetative people.

The Uchiha was disappointed with this result, but the rapid healing of the dragon vein was too chicken.

Just as Uchiha was about to give up and throw these animals out, but when he touched Asuka who had been injected into the dragon vein chakra at the beginning, Asuka Bird's wings actually moved.

Immediately after that, Asuka's eyes also opened, and he looked around in confusion, looking scared when he saw Uchiha far away, flapping his wings and trying to escape.

Of course, Uchiha Yuan would not let the bird fly away, he stopped the bird with a teleportation, and then asked Hinata Akina to help see if there were any strange changes in the bird's body.

Hinata Ayana opened her eyes when she heard this, and after her confirmation, there was no change in Asuka's body compared to before, but the dragon vein chakra had disappeared.

Now every part of Asuka's body has a trace of dragon vein chakra, in other words, the dragon vein chakra is completely absorbed by Asuka by Asuka.

Uchiha Yuan asked Hinata Ayana to use [healing] to wake up Asuka, and Asuka didn't run away this time, but shrunk in fear.

"Yuan, don't you think it's strange? The bird seems to be a little too smart. ”

Uchiha Yuan was stunned when he heard this, yes! This is a bird, where does a bird get such a high IQ?

After that, Uchiha Yuan conducted various tests on the bird, and after the tests, he came to the conclusion that the bird has a higher IQ than the average large mammal.

The breed of this bird is a common gray magpie, which can be found everywhere in both the past life and the Hokage world.

The intelligence of the gray magpie is not even that of a reptile, let alone a mammal.

It is impossible for the gray magpie, a creature with only survival instincts, to have this kind of intelligence, and when the Uchiha picked up this gray magpie from afar before, it did not have any chakra in its body, so it could not be a psychic beast.

In this case, the change of the gray magpie can only be the credit of the dragon vein chakra.

The Uchiha was overjoyed and looked forward to the changes in the other animals.
