After eating the seafood, Ming Yan felt that his whole body was full of strength.

Back at the Akatsuki building, Tsukitomi went on other errands, and Naruto began to ponder the ominous box.

To inject shadow energy into it and condense the shadow crystal nucleus for a year, or even longer, the thought of this made Ming Yan's brain ache.

Try it first.

But the first step stumped him, how can the shadow energy be extracted?

As if sensing his confusion, Zai said: "To extract the shadow energy, you must first sense the shadow energy, and then slowly pull it out through spiritual power. ”

"Induction? I don't even know where the shadow energy is. ”

"It's inside you, you feel it carefully, it's a dark mass of energy, similar to chakra, but much more powerful than chakra."

Ming Yan did as he said, and after a while, he sensed a trace of ability in his lower abdomen that was different from Chakra, it was not as calm as water as Chakra, but a little restless and restless.

Since Ming Yan had practiced illusion, his mental power was not weak, and under the traction of his spiritual power, he slowly channeled the shadow energy to the palm of his hand.

Spread out your hands and observe the changes in your palms as you guide.

Ten minutes passed, Ming Yan's forehead was dripping with sweat, and he was very tired from consuming mental energy, similar to doing coolies, but the so-called shadow energy did not appear in the palms of his hands.

Hang on...... Hang on!

Ming Yan gritted his teeth, and even though his consciousness became a little blurred, he continued to channel that wisp of shadow energy.

Finally, a trace of pitch black appeared in the palm of the hand, like a strand of hair, and it slowly squirmed in the palm of the hand, accompanied by a burning sensation, and a little itchy feeling.

As the Shadow Energy continued to be extracted, it grew thicker and thicker, and later became more like a black earthworm.

It swirls, twists into a ball, and then burrows out of the palm and floats above the palm of the palm out of thin air.

The moment the shadow energy came out, Ming Yan gritted his teeth, his five fingers clenched, and he almost roared out in pain.

As if pulled by some force, it was like a wisp of black smoke, burrowing into the ominous box, and in the originally empty box, a wisp of black gas floated.

"Close the Shadow Box, or the Shadow Energy will be gone." Robbery out loud reminder.

Elapse?!

Ming Yan quickly closed the box, locked it in the drawer, and leaned back in the chair with his head held high like a dead dog.

Extracting shadow energy is a manual job, not to mention the mental trance, and the pain is almost fatal.

If you let the shadow energy pass, it will be a big loss.

After resting for more than an hour, he gradually eased up, and as soon as he came back to his senses, he heard the urging in his mind: "Go on!" ”

"Continue?"

Naruto thought she had misheard, that such hard work was not enough once a day?

"Or else? The little shadow energy you provided just now is not enough for one-ten-thousandth of the energy required by the Shadow Crystal Nucleus, and at your rate, you won't be able to complete it in ten years. He said.

"Alas......"

Ming Yan wanted to cry without tears, so he had to continue to extract the shadow energy, but there was no way, he helped him save Nagato, and he also had to condense the shadow crystal nucleus as promised and read the contents of the box.

He is actually a little curious about the shadow taboo in the box, if he masters the powerful shadow power, it is estimated that even Madara will have nothing to do with him.

After all, shadow energy is an energy that does not exist in the Hokage world, and this force is even more powerful than Chakra, and its existence will undoubtedly make a huge change in the pattern of the Hokage world.

As for whether he will become the next calamity because of the shadow taboo, he is not too worried, because the power of the shadow is not terrible, but the human heart.

Akali is a good proof of this, and the Phantom Sakura Killing Chaos is also a shadow mystery, but Akali has always been consistent with the balance and has not been eroded by the shadows.

Extract Shadow Energy, Rest, Continue, Rest, Continue......

After that, Ming Yan's daily life was like this, hiding in the office every day, and after dealing with affairs, he began to condense the shadow crystal nucleus, and people who didn't know thought that he was busy with work, because every time he saw the second leader, he looked exhausted.

Yahiko and the others were quite puzzled, Naruto didn't have a lot of work every day, so why did he lock himself in the office.

Because of this, Yahiko also talked to Ming Yan, Ming Yan dealt with it casually, saying that he was studying the mysteries of ninjutsu, and Yahiko also believed it, he had no reason not to believe it, every once in a while, Ming Yan would always come up with new tricks, and it was not impossible to stay in the office to study ninjutsu.

The only pastime every day is to take Yue Tong out to eat, outside, Ming Yan introduced her as his sister, in terms of age, Yue Tong is indeed three years younger than him, the identity of the brother and sister is very suitable, Yue Tong doesn't mind, in front of outsiders, a brother is very sweet.

Tsukitomi is unfamiliar with life, so he acts as a tour guide and can protect her well.

A delicate woman who looks so thin that she has no power to restrain her hands and has a disability in her lower limbs, it is inevitable that she will be harassed by some hooligans when she goes out alone, although Yue Tong can solve it alone, but Ming Yan still can't rest assured.

Yuetong's strength has never been shown in front of him, but through a few days of contact, he faintly learned that her attainments in illusion are second to none in Taki's, and it is estimated that she has the strength of ordinary ninja to say the least.

If someone threatens him, she will not hesitate to attack them to protect herself, and if they are murderous, she will not hesitate to kill them.

I'm afraid that kind of hooligan, only teasing and harassing between words, she can't bear to punish at most, so that she will retreat, but this is not always the way, and it is also very hurtful for a girl to play hooligan in words.

But with Ming Yan on the side, this situation will not happen, those who know, know that they are brother and sister, and those who don't know each other will think that they are a couple, in short, with Ming Yan on the side, no matter how much those hooligans covet the posture of the moon pupil, they will always stay away, at most a few peeks.

Ming Yan doesn't wear a red cloud windbreaker when he goes out, but that majestic momentum always makes people feel inexplicably empty, and he always feels that this person is extraordinary.

This kind of life, if you remove the condensed shadow crystal nucleus, it would be better, but it can't.

The shadow energy in the ominous box has become more and more, from the first wisp to a clump, and then from a clump to the current whole box.

The dark and silent shadow energy floated slowly and aimlessly in the box, as if waiting for some opportunity, and then for some time, there were signs of convergence.

It is said that this is a phenomenon of energy contraction, and this stage is very critical, it is necessary to continuously inject shadow energy into the box every day to maintain the basic energy supply, and before long, the shadow crystal nucleus can be condensed, and at that time, the secrets of the shadow box can be snooped into.

In order to condense the Shadow Crystal Nucleus, Naruto paid so much, and Zai seemed to be a little reluctant, so he offered to teach him his other strongest mysteries.

For this, Ming Yan didn't want to refuse and welcome, he took the initiative to propose, he didn't accept it, he looked down on the mystery of the robbery in disguise, so he said, if he doesn't refuse, how many will be wanted......
