In early September, the reconstruction of urban facilities destroyed by the ghost army in the Kingdom of Ghosts was basically completed.

The main miko of the Kingdom of Demons was replaced by five-year-old Shion, and the next sealing responsibility of the demon was also transferred to Shion.

Although she is only a five-year-old girl, due to her special status and responsibilities as a miko, no one looks down upon the five-year-old Shion.

The envoys from various countries who stayed after the ceremony were unable to get the information they wanted from the Kingdom of Ghosts. For this kind of thing, they more hope that the ninjas in the country can make a difference in this regard.

The spies in this area mainly come from the Kumogakure ninjas of the Kingdom of Thunder, the Iwagakure ninjas of the Land of Earth, and the Sunagakure ninjas of the Kingdom of Wind.

Konoha is currently trying its best to reconcile the conflicts at all levels within the village. In addition, it was severely damaged in the Third Ninja War and has no extra strength to reach the distant Demon Country.

Kirigakure has secretly reached an alliance with the Kingdom of Oni. With Yagura, the fourth generation Mizukage, controlling the internal affairs of Kirigakure Village, the Kingdom of Oni has the least to worry about.

Therefore, in the future, the military and secret opponents of the Kingdom of Ghosts will still be the ninja spies sent by the Kingdom of Thunder, the Kingdom of Earth and the Kingdom of Wind.

In the laboratory, a small and exquisite black kettle, only the size of a palm, was placed on the experimental table. Shiraishi looked at the black kettle with a look of great satisfaction on his face.

Then he filled the kettle with water and shouted to Lin who was doing the experiment seriously on the other side: "Lin."

"What's the matter, Teacher Shiraishi?"

Lin put down her work and came to Shiraishi. She saw Shiraishi doing some work around a palm-sized black kettle, and she became curious.

The outer material of the black kettle does not look like metal, but rather seems to be made of ceramic.

If it was just a kettle, this small kettle gave Lin a very strange feeling, but she didn't know what the specific feeling was.

"Teacher Shiraishi, what is this?"

Lin couldn't help but asked curiously.

Shiraishi did not answer immediately, but continued: "Come and use this kettle to pour a glass of water."

"Pour me a glass of water?"

Lin was slightly startled.

Then a thoughtful look appeared on his face, and he stretched out his hand, took the handle of the black kettle, and prepared to pick it up.

As a result, the black kettle remained motionless on the experimental table.

No matter how much strength Lin used to hold it up, it seemed to be fixed there, unmoved.

Lin's face was full of astonishment.

What kind of kettle is this?

Having practiced senjutsu, her strength is not small. Although she cannot exert unparalleled strength like Tsunade, one of the three ninjas, she can easily lift large rocks larger than a human without any problem.

She was curious about what the black kettle was made of.

A black kettle the size of a palm is actually heavier than an adult.

It's incredible.

Lin, who did not believe in evil, continued to increase her strength. In the end, the tailed beast's chakra coat also appeared on the body's surface, allowing Lin's physical strength to increase dramatically again.

However, the black kettle was still fixed there, not even the power of the tailed beast could move it.

Lin gave up the idea of ​​picking up the black kettle. If the black kettle had moved slightly under her power, Lin might have had hope of picking it up.

But the key point is that pure force cannot affect it at all.

This made Lin feel discouraged.

"How does it feel?"

Shiraishi asked interestingly.

Lin thought for a while, then looked at Baishi helplessly and said, "Teacher Baishi, it is impossible to pick up this kettle with pure strength."

Although she was questioning, Lin was sure of her inner guess.

This was not only due to her inner intuition, the Nanao in her body also said something to her - Lin, this kettle is weird. I'm afraid I won't be able to let you pick it up even with all my chakra power.

,give up.

This short sentence shocked Lin.

How powerful is the power of the tailed beast? There is no need to release the tailed beast jade that destroys the world. Just relying on the body to roll can cause huge destructive power, making it difficult for ninjas to compete.

So far, the only ninjas who can confront tailed beasts head-on are a small group of top ninjas in the ninja world.

Most ninjas can only adopt roundabout strategies when facing tailed beasts and dare not confront them head-on.

Moreover, the final defeat of the tailed beast must rely on sealing techniques or special techniques that have strong suppression of the tailed beast's chakra, such as the Sharingan and Wood Release, rather than relying on ninjutsu with astonishing destructive power.

Even the powerful tailed beast found it difficult to pick up this kettle, which made Lin a little unbelievable.

But the Nanao is a relatively gentle tailed beast among the tailed beasts, and does not bother to tell such lies to deceive others.

If it was difficult to lift even the tailed beast, Lin could only suspect that this black kettle was not something special that could be picked up by relying on pure strength.

It takes some special skills to pick up this kettle.

And this special technique can only be explained to her by the creator Shiraishi.

Shiraishi nodded, proving that Lin's statement was correct.

Mere force, no matter how powerful it is, cannot pick up this kettle.

"Then, let's put aside those powers and feel the weight of this kettle with your heart."

Shiraishi gave a more general and vague statement.

The power of intention?

For others, it may be more troublesome.

But for Lin, who has completed the perfect Jinchuuriki training, it is not a strange and difficult thing to use the power of her mind to sense things.

“The power of your heart?”

Lin didn't think much and followed Shiraishi's instructions and picked up the black kettle with her hands again.

This time I don't plan to use my own power, but also the chakra power of the tailed beast.

Feel the weight of this kettle carefully.

Then--

The power of thunder struck Lin hard.

Her expression suddenly changed and she became extremely pale in an instant.

She stood there, holding the kettle, and it seemed as if the world was shaking and turning upside down. Things around her were distorting. Shiraishi's figure disappeared from her eyes, and she saw boundless darkness.

This darkness aroused various dark elements that had long been sealed deep in Lin's heart.

Rather, he wanted to liberate the buried animalistic part of Lin's heart and take over Lin's physical and mental dominance.

Lin's forehead immediately shed layers of cold sweat, and she mustered up all her strength to resist the sudden dark power and suppress all these animalistic qualities.

Dealing with these darkness reminded Lin that when she used to perform the Perfect Jinchuuriki in the past, she could sense the resentment of the tailed beasts in the spiritual space. They were all things that could not be defeated by strength.

This has nothing to do with strength. The black kettle tests people's willpower.

No matter how strong or weak a ninja is, there will always be a gap in the soul, allowing darkness to take advantage of it.

Whether you can pass such a test is the key to picking up the black kettle.

Lin took a deep breath, and the surrounding scene returned to normal. She looked at the black kettle in her hand and felt lingering fear.

I felt inexplicably afraid of something that looked like an ordinary kettle.

This carries a darkness that is more powerful and darker than the tailed beast.

Lin can also be sure that this is not something that chakra can create.

Chakra is just a prop that carries 'things', and it does not produce any darkness in itself.

And this kettle itself may be synonymous with darkness.

It is an abyssal realm that pure chakra cannot reach.

According to what Shiraishi said before, use this kettle to pour a cup of water into the water glass.

Lin took a sip from the water cup and found that the black kettle contained just ordinary drinking water, nothing special about it.

What's special is just the black kettle itself.

"What do you think about using this as one of the required test questions for Ninja School students to finally graduate?"

Shiraishi asked this question.

"I don't think there is a problem. This thing is very helpful in tempering people's willpower."

Lin answered without thinking.

This ninja world is filled with all kinds of temptations, such as strength, money, power, beauty, and other temptations... People spend their lives fighting against these things.

It is impossible to eliminate these things from human nature, but as long as people overcome these things, it will be difficult for their will to be defeated by anything in life.

Failure is never something to be afraid of. What is terrible is that after failure, you do not have the courage to face the setbacks in life again.
To be continued...
