Yamanaka's shadow clone returned to the Konoha camp three days after the main body returned to the Konoha camp before arriving at the border of the Land of Thunder, and Yamanaka couldn't wait to start researching after getting the scroll that sealed the dragon vein.

After the shadow clone is lifted, the memory will return to the main body, and Yamanaka 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.

Yamanaka Yuan unlocked the seal of the scroll and extracted a small clump of dragon vein chakra, which, as previously observed, was made of natural energy and a special chakra.

Immediately after that, Yamanaka Yuan tried to inject the dragon vein chakra into the body of a dying bird, and after absorbing the dragon vein chakra, the bird's injury gradually healed, but it still looked half-dead.

It's a little strange in the mountains, obviously the injuries have recovered, why haven't the life activities resumed?

Yamanaka Yuan took out a cloud of dragon vein chakra from the scroll and continued to inject it into Asuka Bird's body. Then he opened the Writing Wheel Eye and watched the flow of the dragon vein chakra in the bird's body.

With the help of the Sharingan, Yamanaka found that the dragon vein chakra had been circulating in the bird's body, but the bird showed no signs of resuming its life activities.

In the next few days, Yamanaka tested the effects of dragon vein chakras on various animals, and the results were the same as those of the previous birds. The study of the dragon vein chakra was at an impasse for a while.

The Dragon Vein Chakra does have a quick repair effect as Yamanaka Yuan thought, but this quick repair can only affect the body, but it has no effect on 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.

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

Yamanaka was about to give up and throw the animals out, but when he touched the Asuka that had been injected into the dragon vein chakra at the beginning, the birds' wings actually moved.

Immediately after that, the bird's eyes also opened, and he looked around in confusion, looking frightened when he saw the far away mountain, flapping his wings and trying to escape.

Of course, Yamanaka Yuan would not let this bird fly away, and he used a trace of thunderous chakra to stun the bird, allowing your spiritual power to enter the bird's body.

There is no change in the bird's body compared to before, except that the dragon vein chakra has disappeared. Later, under the perception of Yamanaka, he found that every part of Asuka's body had a trace of dragon vein chakra, in other words, the dragon vein chakra was completely absorbed by Asuka by Asuka.

Yamanaka's consciousness withdrew from Asuka's body, and he used the [Healing Technique] to save Asuka, who didn't run away this time, but shrank back in fear.

At this time, Yamanaka Yuan suddenly discovered a new problem, this is a bird, how can a bird get such a high IQ?

Yamanaka then conducted various tests on the bird, and after the tests, he concluded that the bird had 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 gray magpie was picked up in the mountains 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.

Yamanaka was overjoyed and looked forward to the changes in the other animals, but after a few days, Yamanaka couldn't smile anymore.

Yamanaka collected a total of five animals, including the gray magpie, and in the end, only the gray magpie and the hare survived, and the hare's IQ did not change in any way.

Throwing out all the dead animals, Yamanaka's consciousness entered the hare's body, and unlike the gray magpie, the hare did not feel the breath of the dragon vein chakra, which was no different from an ordinary rabbit.

After Yamanaka released the rabbits, he continued to search for other dying small animals for experiments, and injected dragon vein chakras into these animals as before, the difference is that the amount of dragon vein chakra increased according to the size of the animals is also different.

Kushina was curious about the fact that he was far away in the mountains and looked for some animals, but he was stopped by Bo Feng Shuimen.

Bo Feng Shuimen thought that Yamanaka Yuan was studying medical ninjutsu, and when Tsunade was still there before, he often found some small animals to do experiments, and Bo Feng Shuimen had long been surprised by this.

And looking at Yamanaka's state this time, there should be a new breakthrough, and of course Bo Feng Shuimen will not let Jiu Sinai bother.

But where is Jiu Xinnai who listens to persuasion, the more Bo Fengshuimen doesn't let her go, the more curious she becomes. If it's someone else, forget it, Yamanaka Yuan is her precious apprentice, why don't you let her see it?

With this idea, Jiu Sinai took advantage of the wave of wind and water to sneak into the tent of Yamanaka Yuan, who was competing with the gray magpie at this time.

After the gray magpie absorbed the power of the dragon vein, it had a super high IQ, not to mention, a few days ago, Yamanaka Yuan found that it could actually extract chakra.

Being able to extract chakras can already be divided into psychic beasts, which makes Yamanaka Yuan more and more curious about this gray magpie.

But the gray magpie did not stop there, its size gradually grew, the shape of its claws and beak changed, it became more aggressive, and the feathers on its body began to fall off, but the feathers that grew back were silvery white.

Within a few days, the grey magpie turned into a bird with wings spread out for nearly a meter, looking a bit like a falcon.

The root cause of the gray magpie's transformation is the dragon vein chakra, a few days ago, the gray magpie found that Yamanaka Yuan injected dragon vein chakra into the dying animal's body, and he has been pestering Yamanaka Yuan to ask him for dragon vein chakra.

Yamanaka was a little reluctant at first, but after discovering that the gray magpie could produce chakra, Yamanaka was far from hesitating, and gave nearly one-third of the dragon vein chakra in the scroll to the gray magpie.

The gray magpie had the help of a large number of dragon vein chakras, and this completed the transformation. Yamanaka found that the gray magpie had a higher IQ after it turned into a silver falcon, so Yamanaka began to try to teach the gray magpie to speak.

At this moment, Kushina came in, and she watched with some curiosity as Yamanaka Yuan talked to a big white bird.

"Yuan, what are you doing!"

Kushina's voice startled Yamanaka, who was so focused on teaching the gray magpie to speak that he didn't notice anyone coming.

Yamanaka Yuan was about to explain, when the gray magpie suddenly made a voice: "Yuan, what are you doing!" ”

The voice of the gray magpie is a female voice, crispy and beautiful, and the words are very clear, not like they have just learned to speak.

"Yuan, what's going on with this psychic beast?" Kushina asked with some surprise.

"Yuan, what's going on with this psychic beast?" The Grey Magpie continued to imitate Kushina's speech.

Jiu Sinai thought it was very funny, she said that she would imitate a gray magpie, and just like that, a man and a bird played in a tent in the middle of the mountain, and imitated the language.
