Miwa Masayo's reaction after swallowing the pill was much greater than Uchiha Yu's.

The tabby cat is a fire spirit immortal. During her last breakthrough, she mastered the natural energy of the wind spirit, but because she doesn't like wind, she didn't study or practice it much.

The main power contained in the pill he took this time was the natural energy of the thunder spirit, and the natural energy of the fire spirit mixed in during the refining process was not the main component.

The natural energy of the thunder spirit that entered his body could not be directly absorbed and used by Miwa Masayo, which produced a physical alienation effect similar to that of the training at Myoboku Mountain.

The practice of fairy arts at Myoboku Mountain makes the absorption and use of natural energy extremely difficult, at least it is a super jump from 0 to 5, so the degree of physical alienation produced is very extreme.

When the toads smear toad oil on the practitioners of fairy arts at Myōboku Mountain and introduce natural energy into them, they will first be affected by the mixed toad information.

It is even inevitable that the human body will undergo frog transformation and develop frog organs and characteristics.

But the real test is the natural energy mixed with the five spirits. If the practitioner cannot adapt to it in one step, the frog transformation of his body will advance indefinitely until he becomes a real toad.

Mutations in the flesh will inevitably lead to extreme discomfort in the soul. The contradiction between spirit and flesh will destroy the foundation of life. Humans who have completely transformed into frogs are doomed to die.

However, the natural energy will not let him die slowly. Instead, it will madly change the toad's body cells, squeeze out the chakra in the cells, and forcibly transform them into inorganic matter.

In the end, the unlucky person who fails to practice immortal arts will be completely transformed into a toad stone statue.

The magic practice in Longdi Cave is more violent and riskier because the three snake immortals inject poison directly with their fangs.

However, when the practitioner is completely transformed into a snake, he will also transform into an inorganic statue.

The toads of Myōbokuyama are relatively kind. They will use sticks to try to save the practitioners. If they fail, they will watch sadly as the practitioners die from petrification.

However, the snake immortals in Longdi Cave do not have such sympathy. They will deliberately inject more natural energy to increase the difficulty for practitioners to adapt to natural energy, and swallow the unlucky ones after their practice fails.

The practitioner who was completely transformed into a snake but not petrified had his body filled with natural energy, the total amount of which was a hundred times the natural energy injected by the Snake Immortal.

The chakras in their body cells are fully activated under the pressure of natural energy.

For the Snake Immortal, this is the supreme delicacy. Swallowing it in one mouthful is at least as good as the result of ten years of hard practice.

It is precisely because of such benefits that the three snake fairies eat people tirelessly.

If the upper beam is crooked, the lower beam will be crooked too. The big snakes in Longdi Cave followed suit. Even though there was no great benefit for them to eat ordinary people, they were obsessed with eating people, as if they could become snake immortals if they ate enough.

The adaptation to natural energy that Sanlun Yashiro is facing now is not as difficult as the practice of the other two families.

What she is facing is not a qualitative change from 0 to 1, nor a leap from 0 to 5, but an improvement from 2 to 3.

What was absorbed into the body was pure natural energy of the Thunder Spirit, which did not contain any other information, and there was no flaw like a frog turning into a snake.

The only change that occurred on the tabby cat's body was that her fur became lighter in color, especially the light-colored parts of the original tiger stripes, which looked like strands of silver threads.

Up to this point, all of Uchiha Yu's changes in Miwa Masayo were within his expectations, but her subsequent changes were beyond his expectations.

The pain of the tabby cat exceeded Uchiha You's expectations, so he naturally frowned and began to examine it.

But after careful inspection, he didn't find anything wrong.

The veins are unobstructed, the blood and qi are flowing smoothly, and the chakra is stable and abundant. From this point of view, this should be a healthy ninja cat.

Uchiha You thought about it carefully and made a rather risky decision.

He extended his natural energy, carefully wrapped around the tabby cat, and penetrated into her body with the slightest movement.

Through the connection of natural energy, they can not only whisper to each other but also share all their senses.

But at this critical moment, this is the real adventure.

For Uchiha Yu, Miwa Masayo was feeling unwell due to taking the elixir, so sharing his feelings at this time was equivalent to sharing all her pain.

For the tabby cat, the reason for her pain at this moment is unknown. Perhaps Uchiha You's natural energy will detonate the hidden problems and turn the pain into deadly danger.

Fortunately, this did not happen.

Perhaps Uchiha You's caution had the desired effect, and the senses of the two immortals merged into one through the entanglement of natural energy.

The tabby cat heaved a sigh of relief at once. She seemed to be suddenly enveloped in a sea of ​​natural energy. She felt an extremely intense pain, which was suppressed by the sea.

Feeling comfortable, Sanlun Yashio hummed and asked, "Have you found the reason?"

Uchiha You nodded and replied: "I already know the reason."

Then he carefully described his findings.

In fact, the problem is very obvious. Uchiha You discovered the problem with Miwa Masaya the moment he came into contact with her.

The problem lies with the cat fairy's body. Her instinct is to uncontrollably restrict the absorption of natural energy and try her best to repel it out of the body.

This conflicted with the pill she swallowed.

On the one hand, the pill was releasing natural energy quickly, and on the other hand, her body was trying hard to reject it. After the two combined, natural energy flowed through her body at an extremely fast speed.

The natural energy moving at high speed is destructive to the body of the tabby cat, causing its meridians to be scratched and cells to be dislocated.

Her body was like land hit by a flood; it was already a mess, but the large amount of natural energy filling her body temporarily concealed the terrible damage.

When the natural energy fades away, she will feel even worse.

After listening to Uchiha Yu's introduction, Miwa Masaya closed her eyes and thought silently.

After a long time, she opened her eyes, her eyes were empty and blank, and the tabby cat could not think of any solution.

So she looked at the shit shoveler eagerly, and asked with hope in her eyes: "You, how do we solve this problem?"

She trusted Uchiha You so much because this cat-sage, who usually looked very mature, was actually only five years old.

Ever since he met Uchiha You, no matter how difficult the problem is, he can always find a way to solve it, and he has never encountered a problem that cannot be solved.

Therefore, when Miwa Masayo encountered difficulties that he could not solve, he naturally placed his hopes on Uchiha Yu.

Uchiha You did not disappoint her: "There is indeed a way."

He noticed an important detail: Miwa Masayoshi's instinct was not to restrict all natural energy, but only to restrict the natural energy of the Thunder Spirit.

Following this direction, they soon locked onto the base of the tabby cat's tail and the bloodline of the ninja cat.

During her last breakthrough, Miwa Masayo grew a second tail and seven other small bone buds, proving that the maximum number of her tails should be nine.

The ultimate limit for both cats and foxes is nine tails, but a cat’s nine tails represents not only strength, but also life.

When Miwa Masayo grew a ninth tail, she should be called the nine-life cat demon.

No, it should be the Nine-Lived Fairy Cat.

But now it seems that Miwa Masayo's third tail has completely different limitations from the second one.

This limitation originates from Ninja Cat itself, and is even vaguely related to the rules of the world.

Just like when Uchiha You was condensing his golden elixir, the ninja world gave him an unprecedentedly severe disaster, which was brewing layer by layer and continued to advance, almost forcing him to death.

In the end, the golden elixir was successfully condensed, which meant that Uchiha You had officially broken the shackles of life. He was no longer restricted in all aspects and embarked on the grand road of free development.

If he is a little more careful, he can absorb the power of faith, deify himself with a vest, create divine power, and brew godhood.

The tricks that Uchiha You played on Shinto were courting death no matter who was in charge.

For example, when the witch from the Demon Country saw the faith barrier, her face turned pale with fright.

It was not until Uchiha Yu explained that he would be the one to carry the core of the barrier that the shrine maiden Miroku relaxed.

Later, she told Uchiha You that the power of faith was a terrible poison, and once you were infected with it, you could never get rid of it.

The first few generations of shrine maidens did not stay in the Land of Demons all the time. They were able to travel freely in the Ninja World. All they had to do was repair the seal in time before the monsters escaped.

Because the sealing of the monsters made a lot of noise, it is unknown when the witch was believed in by the people of the Land of Demons and inadvertently gained the power of faith.

The power of faith greatly increased the witch's strength, making it easier to seal monsters, which made her very happy.

Later, the witch discovered the terrible power of faith.

The power of faith she received included the hopes of the people in the Land of Ghosts. They hoped that the witch could protect themselves and the Land of Ghosts forever.

The expectations mixed in with the faith slowly changed the witch's way of thinking. Her sense of responsibility towards the Ghost Kingdom grew stronger and stronger, and she became less and less willing to leave the Ghost Kingdom.

When the witch discovered the problem, she made tremendous efforts, even introducing a non-existent god as a shield and hiding herself behind the name of the god, only then did she prevent the power of faith from further eroding her thinking.

But the beliefs she had been infected with before had permanently changed the witch, leaving her imprisoned in the kingdom of ghosts, unable to leave at will.

This is the horror of the power of faith.

Uchiha You faced the same power of faith, but used it without any care, and even further transformed it into more corrosive divine power, but there was no sign that his thinking was affected.

This is the manifestation of Uchiha Itachi being free from the restrictions of the world after condensing his golden elixir and breaking through the shackles of the world.

If condensing the golden elixir represents that Uchiha Yu has broken through his own limitations, then growing three tails is the proof that Miwa Masaya has broken through his own limitations.

In the ninja world, whether it is the two-tailed Nekomata among the tailed beasts, the cat sage Miwa Masayo, and the leader of the Cat Castle, the sage Nekyou, they are all two-tailed cats.

No matter how big the gap in strength is between them, no matter how exaggerated the difference in survival time is, they are all two-tailed.

Especially the Two-tailed Nekomata. From the time it was created by the Six Paths Sage to today, a thousand years later, its strength has increased thousands and tens of thousands of times, but it has not gained an extra tail.

The top cats in the ninja world all have two and only two tails.

And now, among the seven small bone buds at the base of Miwa Yashi's tail, one is flashing with lightning and slowly increasing its size.

This bone bud only accepts pure natural energy from the thunder spirit, and actively rejects the wind spirit and fire spirit.

Because Miwa Masashi's body rejects the Thunder Spirit, the bone bud's ability to absorb the natural energy from the Thunder Spirit is seriously insufficient and cannot support the bone bud's full development and growth.

Uchiha You even discovered that the invisible force that repelled the natural energy of the Thunder Spirit was also suppressing the growth of bone buds.

So the solution is very simple, increase the supply of Thunder Spirit's natural energy, and at the same time prevent the leakage of natural energy, so that Sanlun Yashi's body will be filled with Thunder Spirit's natural energy.

If the bone bud obtains sufficient natural energy from the Thunder Spirit, it may be able to break through the limitations of that invisible force, grow out completely, become the third tail of Miwa Yashiro, and break her own life limits.

"…This is my plan, what do you think?"

"I believe in You, let's do it, meow!"

"It might hurt, just hold on."

"Don't worry, meow. I saw you condensing the golden elixir, meow. I'm prepared, meow."

"Well, let's clean up here first, and then move to another place."

Uchiha You first collected all the pills, and then cleaned up all the garbage produced by alchemy, including the broken cauldron.

Finally, he used the Flying Thunder God Technique and brought Miwa Masayo to the Land of Wind, to a secret room somewhere in the snowy village where the Snow Clan lived in seclusion.

He did not disturb the children of the Snow Clan, and quietly flew to the depths of the desert with the tabby cat.

Miwa Masayo asked, "You, why are you in the Kingdom of Wind? I thought you would take me to the Kingdom of Thunder."

Uchiha You replied: "Because the Great Desert is the environment where the Ninja Cat was originally born, it is more suitable to break through here."

The tabby cat nodded, then shook his head and said, "But, you said that what I need for my breakthrough is the natural energy of the Thunder Spirit, meow."

"In the Great Desert, the natural energy of wind spirits is the strongest, while the natural energy of thunder spirits is relatively thin. Is there really no problem?"

Uchiha You rubbed the head of the tabby cat and replied: "This time is different, you don't need to absorb the natural energy of the Thunder Spirit from the outside world, you only need to eat more pills to meet your needs, so there is no need to go to the Land of Thunder."

"The main purpose of my refining the pill is to eat it, but it is also to be able to get rid of the restrictions imposed on us by the environment at this critical moment."

"Lihua-chan, I noticed last time that you seemed to be at ease in the desert, and you were in a very good mood. Mood is also helpful for breakthroughs."

"With the elixir, we don't need to worry about the natural energy in the environment, but of course we can consider the impact of the environment on our mood."

Uchiha You flew very fast and soon found a remote and uninhabited area, and landed with Miwa Masayo.

Although he felt very uncomfortable, the tabby cat's eyes lit up when he landed on the sand: "You, you're right, meow. My paws stepped on the sand and I felt relaxed all of a sudden."

Uchiha You smiled and said, "That's good, let's get started now."

After saying that, he clasped his hands together and launched a ninjutsu.

Wood Style: Multiple Wood Wall

Densely packed wooden pillars emerged from the sand and bent to form ten layers of arches, protecting Uchiha Yu and Miwa Masayo underneath.

Uchiha You stood in the center of the wooden wall, releasing a large amount of natural energy of the thunder spirit. Countless lightning bolts traveled along the gaps in the wooden raft but could not escape from the gaps.

After confirming that the wooden ingot wall was perfectly sealed and would not leak any natural energy, he took out a handful of pills and handed them to Sanlun Yashi.

He said to the tabby cat, "Lihua Jiang, eat them one by one. Don't stop even if it hurts, but don't eat two at a time."

As he spoke, Uchiha You released more natural lightning energy, causing the density inside the wooden wall to reach its limit and even penetrating into Miwa Masayo's body.

Through these natural energies, he is absolutely sure to control all changes in the body of the tabby cat and prevent an irreversible situation.

"I'm ready, don't be afraid, Lihua-chan, let's get started."

Miwa Masayo nodded, put the first pill into his mouth and swallowed it in one gulp.

Feeling the burning and numbness in his body, as well as the tearing pain running through his spine, the tabby cat smiled and said, "I'm not afraid, meow. With You's help, there will be absolutely no problem, meow."

Just like before, Miwa Masayo's body continued to reject the thunder spirit, but because the concentration of the thunder spirit's natural energy in the external environment was too high, the thunder spirit in her body could not be rejected.

Under the tremendous external pressure, Miwa Masayo didn't even feel the swelling of his body.

The bone buds on the coccyx finally came into contact with the rich natural energy of the Thunder Spirit. The power of growth was fully supported, causing a fierce conflict with the invisible force that prevented its growth.

A bolt of lightning exploded from the tabby cat's tail, tearing its fur and hitting the inside of the wooden ingot wall along with blood.

At this moment, Miwa Masayo finally couldn't bear it anymore and let out a scream.

Uchiha Yu did not stop the lightning.

Because this lightning struck without any warning and its speed is so fast, it cannot be foreseen in advance and cannot be stopped.

Moreover, although this lightning caused considerable damage to the tabby cat, its powerful vitality was also stimulated afterwards.

Under the stimulation of huge vitality, the torn wound healed quickly, wrapping up the bone buds that had just emerged.

Judging from such subsequent performances, the lightning emitted from Sanlun Yashi's body is very similar to the lightning of thunder tribulation he encountered in the past, and it has the characteristics of both destruction and vitality.

However, this lightning did not fall from the sky, but came from the bone buds of Miwa Masashi.

The closed fur did not last long, as the bone bud absorbed enough natural energy from the thunder spirit again, sparking another identical lightning bolt that tore its fur apart again.

This time the bone buds did not give the fur a chance to heal. Every joint was developing and growing rapidly, and a white bony tail grew out like a bamboo shoot after the rain.

Immediately afterwards, the vitality stimulated by the lightning spread to the white bony tail, and white fascia emerged from between the joints, and pink muscles grew on the fascia.

Less than a minute after the white bones grew out, the pink tail was able to swing flexibly.

After two minutes, the skin of the tail is fully developed.

Three minutes later, soft fluff grew out of the pores and a golden ring-shaped cat's tail emerged.
