There is no sun and moon in cultivation, and more than seven years have passed in the blink of an eye.

Shi An in the Cave Heaven Stone had already built the foundation of the five spiritual roots at this time.

Since coming out of the courtyard and entering the Cave Stone again, it took three and a half years to build the foundation of the fire spirit root, and another three years to build the foundation of the earth spirit root, and the last golden spirit root no longer needed to nourish other spirit roots, so it only took eight months to build the foundation successfully. Of course, in addition to the huge effect of the Spirit Gathering Array, Jin Hu Dan also played a big role. Now Shi An is already a genuine monk in the early stage of the foundation building of the Five Spiritual Roots.

Looking at the body again, the whole body is covered with white, green, blue, red, and yellow five-color spiritual root branches, the sea of qi is surprisingly large, three times the size of an adult's fist, and there is a thin layer of Dan liquid at the bottom of the sea of qi, and the white, green, blue, red, and yellow five colors are arranged vertically and distinctly. The thickness of the spiritual roots is similar, and the amount of pill liquid is basically the same, so it seems that the balance of the five spiritual roots mentioned by the mother has been realized.

Shi An's "Soul Splitting Dafa" was completed only half a year after Xiaocheng, and the speed made him smack, it seems that the ability of the futon to nourish the soul is far beyond his original expectations. According to the "Soul Splitting Dafa", when the soul grows to a small level, you can cultivate the second layer, and in the future, you can practice the technique of summoning the two souls of heaven and earth while strengthening the soul of life, which is also Shi An's original plan. However, during a meditation in the first few days, he wandered out of the world after entering the futon, and when he came out of the time, he found that the first layer had been completed, which he did not expect. If it weren't for Wu Gang saying that he hadn't seen the shopkeeper Shi for half a year, Shi An wouldn't have known that this time he had been in the house for half a year.

It was too simple to cultivate the second layer after Dacheng, and in just one year, the Heavenly Soul was summoned by him. The moment a ball of light the size of a dark blue bronze mirror appeared, he felt that his mind had split into two halves, half of which was in his body as usual, still feeling his condition. The other half is attached to this ball of light, and all its feelings can be perceived at the same time. This ball of light is the Heavenly Soul, and at this time, the Heavenly Soul is not driven by him, and it is still running around in the Cave Heaven Stone according to its instincts. So Shi An began to try to contact the Heavenly Soul and drive it according to the second layer of the Soul Summoning Technique in the "Soul Splitting Dafa".

After that, it was another half a year, and when this ball of light acted according to Shi An's mind like an arm, this was one of the true soul splits.

With the experience of summoning and driving the Heavenly Soul, it took only one year to summon and drive the Earth Soul the size of a bronze mirror. Therefore, the second layer of the Soul Splitting Technique was cultivated to its full completion, and Shi Anyi spent two and a half years.

The third layer is the "Soul Strengthening Technique", which is to double the original number of the two souls of heaven and earth. Since the two souls of heaven and earth themselves are outside the body, Shi An arranged for them to burrow into the futon all day long to nourish, at first the blue and yellow two light balls were like children inseparable from their mothers, and after discovering the warm and comfortable feeling that the futon brought them, they were like mortals hiding in the quilt in the bitter cold, and refused to come out again. By the time Shi Anjin Linggen appeared, the two guys had already been "fat".

Now the time is ripe to begin the fourth level of practice.

The fourth layer is the "Soul Splitting Technique", and the cultivation of this layer is to divide the two souls of heaven and earth into two to form four split souls. This is the most important and painful and difficult practice in the Soul Splitting Dafa, which Shi An has experienced deeply in his eight-month practice.

It is not as easy as the splitting of the divine consciousness, the divine consciousness is the advanced stage of consciousness, and as long as the sense of touch is turned off, there will no longer be pain, so under the drive of the distraction, it will naturally split like a ripe melon. The split between the two souls of heaven and earth is very different, it is free from the body, there is no divine sense, and it is naturally unable to close the pain, and its split is naturally as painful as Shi An's own body being split in half.

Especially the pain when he split the Heavenly Soul for the first time, Shi An still has palpitations in his heart when he remembers it.

At first, he summoned the Heavenly Soul to prepare for splitting, and his thoughts were already the same, and the Heavenly Soul also knew that he would be divided into two later, so he refused to show up. Shi An had no choice but to summon the earth soul to help, and even dragged the ground to pull out the big blue round ball from the far corner of the futon. When the Heavenly Soul secretly scolded the Earth Soul for not being righteous, and the Earth Soul turned its fat body like a gloating, Shi An couldn't cry or laugh.

When I read the book, I knew that the process of splitting the soul was extremely painful, and Shi An had already prepared for this. Stop any cultivation content in your hand, empty all your minds, combine water balloon techniques and fireball techniques, and soak yourself in a hot bath. For five whole days of total relaxation, this was something he had never done since entering the Immortal Cultivation Realm, just hoping that it could help alleviate the pain of splitting his soul.

After everything was ready, Shi An sat on the futon and began to chant the mantra, the entire body of the Heavenly Soul immediately froze and could not move, and the Earth Soul also quietly slipped to a dark corner of the Cave Heaven Stone to observe secretly, and it also knew that it would be its turn next.

After the mantra was recited, the Heavenly Soul began to split, and an extremely bright golden yellow dot appeared from the middle of this ball of light, which began to slowly expand along the four directions of up, down, left and right, and gradually expanded from a small golden dot to a small circle, and the circle became larger and larger, until the entire blue ball of light was divided into two hemispheres that were closed together.

This process took three days, and Shi An didn't feel anything in the sea of knowledge during this process. But when the two hemispheres separated by this circle began to gradually separate, the pain began.

The pain is like a wave rushing towards the shore, at first it is gentle and unhurried, and then the wave gradually increases and becomes stronger and stronger, until it becomes a huge wave that crashes against the shore. In Shi An's view, at first, the pain was like a silver needle piercing the skin during acupuncture, and there was a slight itch in the stinging pain; then it was like cutting a finger with a piece of paper, but it was sharper and longer, and then it was like boiling water splashing onto the belly, but it was more burning and more intense; and then like a big saw cutting off an arm, an axe chopping off his head, and chopping up internal organs, Shi An also went from sweating profusely at the beginning to nausea and vomiting, producing extreme fear and a sense of impending death, until finally fainting.

What pained him the most was not the pain, but the lack of hope. Every time he was woken up by pain, his hazy eyes only saw that the ball of light was still connected, and there was no sense of separation, and the pain was not only not alleviated, but became more and more intense, all this was like a dying person drifting on the boundless sea, with no end in sight, no hope, at this time he had only one wish, that is, after passing out, he would never wake up again. Heaven did not fulfill people's wishes, that is, to wake him up once in half an hour, so that he could taste the pain of tearing his soul repeatedly, and so on for more than half a month.

When he woke up for the last time, he saw that the two blue hemispheres were finally separated, and the moment the golden circle disappeared, the two hemispheres immediately turned into two identical spheres, the size of the original Heavenly Soul.

"Alas, it finally succeeded!" The current Shi An does not have the joy after success, but only the relief after the pain disappears.

Splitting the two heavenly souls is not as peaceful as Shi An imagined, constantly colliding with each other, as if they want to confirm their leadership position. Because of the same heart, Shi An knows what they think, and these two guys also know that Shi An is the boss, and the order of the two is assigned by the boss.

So as soon as Shi An's mind moved, they rushed to Shi An's side. Shi An pointed casually, "Remember, in the future, you will be a big blue, and you will be a little blue." After the big and small blue got the name, they no longer clashed, and rushed to the peeping earth soul in the corner together, pulling it left and right to play.

Shi An was so tired that he no longer had the strength to control them, so he sat on the futon and kept his soul, and soon settled down.

This time, the time of entry was half a month, and after the decision, he did not dare to continue to split the earth soul, but made up for the spiritual energy absorption that had not been carried out for more than 40 days due to the splitting of the heavenly soul.

Half a year later, when Jin Linggen had also laid a foundation, Shi An planned to split the earth soul.

The preparations this time are exactly the same as last time, the difference is that this time it is the big blue and the little blue who are smiling, and it is the earth soul that is trembling in the futon and refuses to come out. Erlan, who had been nourished in the futon for half a year, had grown in size compared to when he first split, and after capturing the earth soul, he did not hesitate to carry it to Shi An's side. Shi An was also very hesitant to suffer that pain again immediately, but a message came from the sea of knowledge, telling Shi An that he could help with the division of the earth soul, so as to greatly reduce the pain and time spent during the split.

Shi An began to be suspicious.

I don't know if it was because the big and small blue spoke reliably, or if he was used to the painful experience of the last time, the split of the earth soul was much smoother, during which the big and small blue desperately helped tear the two yellow hemispheres, so that the split was completed in only ten days, and the number of times he was unconscious was greatly reduced. When the big and small two yellows and the big and small two blue roared around Shi An, the fourth layer of the "Soul Splitting Dafa" was finally completed.

Now that there are a total of five sub-souls in the upper life soul, and the five spiritual roots have also entered the foundation building period in a balanced manner, the next step is to use the five sub-souls to control a spiritual root for the cultivation of the foundation building period.

As for the fifth-layer doppelganger technique, Shi An doesn't plan to cultivate it now, and he really doesn't have the conditions to cultivate, because the first condition of this layer is the primordial infant stage, and the second condition is to have the connection itself, and there must be a total of five five-element life carriers with different attributes.
