Fortunately, the Land of Thunder did not disappoint Yun Feng.

When he couldn't hurry by night, Yun Feng went to the country of thunder in advance to search. The towering peaks everywhere are excellent cover, not too damaged by technology, and the aura is quite strong.

In just over three months, the team of children and teenagers around ten years old had grown to sixty-five people, which was also the number of people who finally arrived at the peak chosen by Yunfeng.

Children don't need Yun Feng to worry, they have Terashima to take care of, and the oldest of them is already fifteen or sixteen years old, and in such a chaotic era, they have already learned to take care of themselves. Along the way, I have seen too many war tragedies, and almost everyone is looking forward to a stable place to live away from the war, and they are only left to rely on Yunfeng and Terashimami, who have always taken care of themselves.

The mountain selected by Yunfeng is surrounded by three mountains arranged in an irregular triangle, the mountains and rivers are beautiful, towering into the clouds, full of various trees and plants, in addition to three mountain springs and a small waterfall, there is even a hot spring, which is used for seclusion and cultivation, which is simply suitable.

However, the first thing Yun Feng had to do was to set up the formation.

Many of the classics of the Water Moon Palace involve formations, and the Water Moon Palace, where Ling'er and Grandma lived back then, was also shrouded in formations, and the faint mist covered the islands in the lake, making it impossible for people to discover the secrets.

In addition to the formations used to protect and cover people's ears, the most important is the magic array modified by Yun Feng and Anastasia together, the last Runi.

The Cloud Peak of the Spirit Gathering Array can also be arranged, but that kind of formation is very slow for condensing the surrounding spiritual energy, and it is an extremely gentle formation, allowing the surrounding spiritual energy to slowly flow to the core of the Spirit Gathering Array. And the last runi is different, it is more like a kind of plunder, almost using a robbery method to gather aura, which is more efficient. In this world, only those so-called immortals can feel the aura, and they have long since died, so Yun Feng doesn't need to care about their thoughts and opinions.

Dozens of colorful spars were condensed with Samadhi True Fire, and then placed them at the nodes of the formation one by one, and it took more than two months for Yun Feng to complete the arrangement of the formation.

The peaks above 300 meters high are gradually shrouded in clouds and mist, and they can no longer see what is inside, even if someone unintentionally climbs this mountain, they will be confused by the maze arranged by the cloud peak, and they will not leave here without any discovery. If there is an enemy, there is also a phantom array and a killing array, with the help of the power of the formation, even if it is the state of the Uchiha Obito with the state of the Six Dao Immortals, Yun Feng is sure to destroy him.

Chakra is a little stronger than the internal force, but Yun Feng still has two internal force cultivation methods. Both of these energies are extracted from the human body itself, and there may be something in common, even if they can't be cultivated at the same time, there are children who are not suitable for ninjutsu to have a choice.

After settling everything, the Yunfeng Church Temple Island saw the entry and exit formation, and then officially retreated and cultivated.

The concentration of aura was not enough, Yun Feng did not rush to condense the true element, but first began to cultivate the shadow clone and the Flying Thunder God technique.

Wan Jian Jue and Yun Feng's self-created phantom sword are also a kind of clone, but they are item clones. Relying on the power of the magic weapon, the sword of the Ten Thousand Sword Technique is the same as the entity, almost the same as the entity. Starting from the Ten Thousand Swords Technique, Yun Feng figured out the trick of the shadow clone technique little by little.

It is only the first step to conjure up a clone with a real ** with the true element, and this first step alone took Yun Feng more than half a year to perfect, and what makes him discouraged is that unless the completed doppelganger is allowed to cultivate again, it will be a body with a strong **, and it will be useless except for physical skills.

The shadow clone separated by Chakra is a physical clone, so it can extract the Chakra in the body again, and the true element is obtained from the accumulation and cultivation of Yunfeng little by little from nothing, and it is impossible to change out of thin air.

"What's the use of getting you out? There's no real element at all, you're useless except to be cannon fodder! ”

Yun Feng wanted to cry without tears and cried to the clone that was easy to practice, did he let the shadow clone learn ninjutsu?

"You can't say that! You have so many wives, you can share one by one when the time comes, and they will be lonely in the province. ”

Yun Feng almost vomited blood, this product is indeed good for himself, and he has such dirty thoughts. But it's not bad to think about it, a picture of inappropriate children flashed in my mind, well, next time I try to deal with that little girl of Anas with the doppelganger technique, I won't kill him.

Shaking his head, Yun Feng threw these thoughts out of his mind, and said with annoyance: "My wife belongs to my wife, even if it is a doppelganger, don't want to take advantage." Try it and see if you can use ninjutsu! ”

The clone shook his head very dryly, "The extraction of Chakra needs to start cultivation again, even if I can use it, I must slowly cultivate in this state, and it can't disappear, because you are my body, and you can't use ninjutsu." Therefore, once the clone is canceled, the clone must start cultivating again, and the gains outweigh the losses! ”

It's terrible, Yun Feng scratched his head frantically, it took him almost a year to perfect this spell, and it didn't even work, this is just a cheat.

"Why don't you catch a tailed beast and seal it into your body?"

The doppelganger looked at his own body with great disdain, obviously there was a better solution, why did he have to drill the horns.

"If it weren't for the fact that you're the body, I'd love to spit on you. Don't you see where this spell is really powerful? ”

Yun Feng looked dazed, chatting with himself, which already made him feel crazy, and he was despised by himself, which was unreasonable.

"Where?"

"What's the difference between you and me?"

"You are a doppelganger, I am the essence, except that you can't use my power, it's no different."

"That's where it matters!" The doppelganger looked solemn, "In my opinion, the strongest part of this spell is that the doppelganger you separate is another self, not a puppet manipulated by the soul. If I go out, as long as you don't unlock this spell, you will be no different from ordinary people, you can have your own feelings, your own life, don't you understand? ”

Yun Feng closed his eyes and pondered for a long time. As the doppelganger said, this is the characteristic of the shadow doppelganger's technique, which does not need to be manipulated, and the doppelganger can act with its own will, but because the two thoughts and memories are separated from the ontology, they can cooperate seamlessly. The doppelganger understands because he has no strength, but he is bent on making a clone that can perfectly use the power of the body, and that kind of spell is probably a level that he has absolutely no strength to touch at present.

You can't use the true element, you must still be able to use it skillfully, you can separate, Yun Feng's eyes are getting brighter and brighter, and there is indeed a power in his body that is suitable for using on the doppelganger technique.

"Looks like you've finally figured it out!" The doppelganger said triumphantly. Because he is the essence of Yun Feng, his thirst for strength is the same as Yun Feng, and he can't use the power of the true yuan accumulated by Xiuzhen, so there is only one power to consider.

Yun Feng pinched a trick in his left hand, which was the handprint of the canceled clone, and said with a smile on the corner of his mouth: "Although you are my doppelganger, I still want to thank you." ”

"Alas...... If you want to thank me, at least let me go out and have fun, not ......."

The doppelganger disappeared without a trace with a sigh.

Sure enough, it is a bystander, even if it is just his own doppelganger, it can indeed be clearer from another angle.

Yun Feng not only had the True Yuan in his body, but more importantly, there was also the Devil Fruit, this kind of power was not worth mentioning in front of the cultivators, but there was no doubt that it was indeed an extremely powerful power. On top of that, each Devil Fruit has different abilities and is simply inherently prepared for the doppelganger. Yun Feng is now a little glad that he participated in that experiment, otherwise the doppelganger technique he got now would be pure cannon fodder in the face of a strong enemy, but based on the doppelganger of the Devil Fruit, it can no longer be regarded as a pure doppelganger technique, so it is called a demon clone.

The difficulty of fusing the different laws of two or even three worlds together can be imagined, if it weren't for the fact that these worlds were all created by Yun Feng, it is estimated that there would be no doors, not even windows.

Thinking of it and doing it is Yun Feng's character.

Really doing it, Yun Feng found that the difficulty in the middle was even more difficult than he imagined.

Getting the Devil Fruit into the clone while the clone is out is extremely difficult to operate, but it is not impossible to find it.

In the world of the Wagtail Goddess, Yun Feng sensed that Qiujin Fenghua Moon Haiyan could borrow the power of the corresponding Devil Fruit in his body by kissing, but only with his permission. But this time it's your own doppelganger, can't you let yourself kiss yourself? Thinking of that picture, after summoning a bunch of doppelgangers, he kissed them one by one, Yun Feng was so hung that he vomited, and he didn't have such a narcissism, so he vetoed it directly.

Try, fail, try again, fail again, referring to the cultivation of the true technique and the warlock's soul magic and the shadow clone technique and the flying thunder god's technique, Yun Feng didn't even remember how long it had been, and finally completed this spell that only he could use.

The aura condensed by the last runi was also full to the point of being amazing, and Yun Feng finally let go of his mind and began to concentrate on cultivating. What he has always walked is the path of transcending all cultivation, and the spell of battle is only a side path after all.

The method of gathering qi modified by the spear mode of the main god and the large array that enveloped the entire mountain outside echoed each other, and the surging aura was like a river in the sea and returned to the river, pouring into the body of Yunfeng, and after wandering and condensing in the meridians in a mysterious way, it finally merged into the golden pill of the lower dantian. The soybean-sized golden pill slowly grew in size at a speed visible to the naked eye, and eventually turned into a round ball the size of a ping-pong ball.

This is already the extreme that Jindan can accommodate the true yuan, and if you continue to cultivate, you must break the Dan into a baby in order to improve the realm, otherwise you can only be trapped at the level of Jindan.

The aura that was originally like a small river turned into a raging river, and Yun Feng did not hesitate any longer. Breaking the Dan requires a large amount of aura, and it must be done in one go, at the moment when the Jindan is broken, it will be combined with the Yuan Shen to form a new Yuan Baby, if you don't grasp this opportunity well, you will explode and die. Based on the aura that Jin Dan accommodates at the moment, it is probably enough to wipe out most of the Thunder Country, and you must know that the land area of the Thunder Country is equivalent to two-thirds of Huaxia.

The storm formed by the aura had already swept up the clouds and mist of the entire mountain peak, like a hurricane, but fortunately, Terashima, who had long sensed that something was wrong, took everyone to hide in the cave in time and escaped. But such a change in heaven and earth made Terashima see extremely frightened, could it be that this is the result of the master's cultivation?

Jin Dan was finally exploded by an innumerable amount of spiritual energy, and Yun Feng's primordial spirit had already been waiting for it, and pounced on it at the moment when the spiritual energy exploded, like a greedy baby, inhaling the violent spiritual energy into the virtual shadow that was almost condensed into a physical body, and finally formed a baby with the same appearance as Yun Feng, slowly sitting in the dantian.
