In the bamboo forest, Su Chen meditated.

He needs to guide his aura to merge into the golden pill, and cast the sword soul with the divine fire of the heart, as long as the sword embryo is successfully cast, he has entered the god refining period.

Reiki is a formless and insubstantial thing, but the monk can incorporate it into his body through a special method of breathing and becoming his own power, and then the aura will appear in a certain form. And aura is the foundation of all cultivation, whether it is the alchemy of the Jindan period or the forging of the gods during the refining period, it is based on aura.

The divine fire of the heart is a rootless fire, which is owned by the human body. Casting the sword soul or condensing the yuan infant is to calcine the invisible aura with rootless fire, and turn the void into reality with no refining.

Jindan is the place where the monk's aura is most intense and concentrated, and it is also a hub. When a monk enters the period of refining the gods, he wants to turn the golden pill into a furnace and open the road of "refining the gods".

The heart fire had already burned, and Su Chen had been guiding the spiritual energy to gather into the golden pill and bear the calcination of the heart divine fire. Jin Dan also has a wisp of his divine thought in the lead, so as to cast the aura into a sword shape, and this wisp of divine thought will eventually become the "soul" of the sword soul.

Sword cultivation replaces refining gods by casting swords, and at the beginning of the advancement, there is no need to spend time refining the "gods" in the body. But sword cultivation still has to "refine the gods", but unlike ordinary monks, sword cultivation only makes its own primordial spirit transform from virtual to real, and does not merge with the sword soul, otherwise it will be no different from turning into a baby.

The process of forming a sword soul is very time-consuming, and the sword casting in the earthly world cannot be completed in a day or two. And the sword soul is related to the future of sword cultivation, and it is necessary to grow together with sword cultivation, so it is even more necessary to temper it repeatedly, remove the chaff, and obtain the purest Dao sword.

Su Chen didn't know how long he had been in retreat in the bamboo forest, he had been paying attention to the sword soul in his body, and he couldn't relax in the slightest.

The aura is like fog and water when it runs in the body, and when it gathers in the golden pill, it is completely foggy, and now under the calcination of the heart fire, the golden pill is already a piece of mist, and the aura has turned into rain, falling in a torrent, and after encountering the fire, it atomizes again, so that the cycle continues, and the aura is constantly purified by the heart fire. Then Su Chen channeled the repeatedly purified aura to one place and cast these aura into a sword. And although the aura within his golden pill is very abundant, there are very few that can reach the level of aura that can be used to forge swords in the current realm.

"Forging a sword is more time-consuming than refining a god, and everything can only be done step by step. Su Chen's heart was stable and he was not in a hurry at all.

And at this time, his sword soul didn't even have an outline.

"It's so boring, why hasn't Su Chen come back after going for a month. ”

The moon was in the middle of the sky, and Xiyue stared at the pear tree, extremely bored. Xiao Zi lay on her stomach in her arms, letting Xiyue caress the soft hair on her back, sleeping soundly.

It's no wonder that she was bored, after Su Chen's retreat, Long Qingyan disappeared all day long. On weekdays, only Xiao Zi accompanies her, either practicing or taking care of the pear tree, and at night she is with Xiao Zi, without Su Chen chatting with her and telling her stories, Xiyue is very unaccustomed to it.

"When did I get used to having someone to accompany me?" Xiyue stared at the night sky with only one crescent moon and muttered to herself, "I still want to spend this Laba Festival with the two of them, it seems that there will be one less person anyway." ”

In a few days, it will be the Laba Festival in the world, and it will also be the second Laba Festival after the three of Xiyue met. Last year, I happened to meet Long Qingyan in retreat in the Sun Pit, and this year it was Su Chen's turn.

"However, there is still a long way to go, and it will not be like this every year. ”

Xiao Zi turned over, arched in Xi Yue's arms, and changed to a more comfortable position, Xi Yue smiled, shook her head, and got up to go back to the room.

When I got up the next day, I opened the door and saw that it was snowy, and the pear tree was full of snow.

Xiyue showed a smile, and then thought of Su Chen, who was still in the bamboo forest, and suddenly wanted to go and see, so she didn't wake up Xiao Zi, who was still asleep, and quietly went to the bamboo forest.

The bamboo forest is also covered in silver, and there is still light snow at this time. Xiyue held an oil-paper umbrella and stepped on the snow, and saw a figure in the snow from a distance, but it was already covered with snow, but the person still didn't feel it.

Su Chen's surroundings were very safe, and Xiyue could approach at will, and she couldn't help muttering, "You also said that I don't have defenses when I practice, and you're not like this yourself?" However, the scene here is different from what she imagined, and she thought that Su Chen must be alive at this time.

She held an umbrella in one hand and blocked the heads of the two of them, while the other hand carefully brushed the snow off Su Chen's face and hair, for fear of disturbing his cultivation.

Looking at this delicate and quiet face, Xi Yue sighed with emotion, the two had known each other for nearly two years, and she still vividly remembered the scene when they first met in the Qitian Mountain Range. Sometimes Xiyue also thinks that her friendship with Su Chen is so desperate, although it stems from that prophecy, but now I'm afraid it's no longer just because of the prophecy, right?

The answer is obvious, but Xiyue often thinks that she seems to prefer to get along with Su Chen than Long Qingyan, what is the reason for this?

Was it because they had known each other earlier, or was he always going along with him, or was it because he would make good food and tell a lot of stories she had never heard before? Or was there something else going on in that?

"I don't know why, I'll miss you more. Xiyue looked at Su Chen with her cheeks raised, and couldn't help but reach out to pinch his face, but her hand was halfway out and put it down, because she remembered that Su Chen was cultivating, so she withdrew her hand stupidly.

The scenery here was very monotonous, Xi Yue lost interest after looking around, and after taking another look at Su Chen, she was ready to leave.

Su Chen's sword-forging continued, and he didn't know that Xiyue had ever been here.

A month has passed, and his sword soul has already taken shape, and everything is proceeding in an orderly manner, although the progress is slow, but at least it is smooth.

In a blink of an eye, it was the thirtieth day of the lunar month.

This night was quite long for Su Chen, because he was in great trouble.

For some reason, the mysterious black and white qi that had been entrenched in his body had always been very quiet, but when the time came this night, it suddenly rioted.

The black and white qi did not maintain balance in the form of Tai Chi, but turned into two sword qi, one black and one white, and rushed into the golden pill. Su Chen was shocked, and hurriedly mobilized the aura to block it, but the black and white sword qi was like a rainbow, and it couldn't be stopped at all, and the arrival of the black and white sword qi triggered a riot of the aura in the Jin Dan, and inside the originally calm Jin Dan, the aura was out of control, scattering and impacting, hitting the Jin Dan to almost pieces, and the black and white sword qi directly defeated Su Chen's almost formed sword soul!

This night, Xiyue and Long Qingyan felt a shaking of the sky at the same time, and the two came out of the room and found that the sword qi was rushing in the bamboo forest, and they felt that the aura was surging and sweeping, so they hurriedly went to the bamboo forest to check the situation.

At this time, the snow accumulated on Su Chen's body had already collapsed, and the scattered sword qi mixed with the aura between heaven and earth, destroying the ground around him, and strangely, those bamboos were not damaged at all.

"What's going on?" Xiyue was completely anxious, and everyone could see that something must have happened to Su Chen.

"I don't know, but most of us can't help. Long Qingyan frowned, he picked up a stone and threw it at Su Chen's side, the stone did not come to him, and it turned into powder about three feet away from him, and the two of them were shocked.

"I'll give it a try. Xiyue said, and walked forward with an extremely solemn expression.

With Su Chen as the center, an invisible field was formed, and when Xi Yue slowly approached, she could feel a repulsive force, pushing her away, and the closer she got to the center, the stronger this force became, still about three feet away from him, Xi Yue couldn't even lift her hands and feet, she could be sure that if she moved a little, she would inevitably be rebounded by the invisible field.

In the end, Xiyue had no choice but to retreat, and Long Qingyan also tried to get close to Su Chen, but unfortunately failed.

"It's a pity that Dugu's predecessor is not here, otherwise there must be a way, and now he can only rely on himself. Long Qingyan let out a long sigh and held down Xiyue, who still wanted to move forward.

"It's just him!" Xiyue bit her lower lip and said worriedly.

At this time, Su Chen was trying his best to suppress the black and white sword qi in his body, and everything was caused by these two mysterious forces, which made Su Chen's hard work for this period of time come to naught, and he felt anger in his heart, and even a trace of despair.

The sword soul has been shattered, which means that the opportunity to break through the level this time is gone, and this is not the most serious thing. The riot caused by the black and white sword qi destroyed his golden pill, and now he doesn't want to say "forging a sword", it is difficult to say whether he can keep his current cultivation, and now he can only try his best to protect himself.

Fortunately, he had taken the Taiyin Pill once, and his meridians were extremely flexible, and he could barely withstand the impact of the riotous aura, but his Jin Dan was miserable and had been completely shattered.

The black and white qi changed back to its previous appearance, and after making trouble, it quieted down again, hovering around Su Chen's tattered golden pill, but leaving Su Chen with a big mess.

What to do?

Su Chen thought hard, and the only thing he was glad about was that the black and white qi calmed down, and he spent some effort to stabilize the situation in his body. The fragments of the golden pill were still shining with golden light, and the sword soul was completely gone. After a long sigh, Su Chen could only reunite with Jin Dan first to keep his cultivation intact, as for the sword soul, he had to think about it carefully, it seemed that it was precisely because the sword soul was about to take shape that it attracted the attack of black and white.

However, why did this black and white qi attack his sword soul?

Su Chen gradually calmed down and re-explored his own situation, maybe there was something he overlooked, and that was the key.

In the sea of chaotic qi, Jin Dan was slowly condensing, and Su Chen accidentally found that there was a faint golden wire connecting the fragments of Jin Dan, and his cultivation was actually not affected, which made him puzzled. During the reunion of Jin Dan, there was peace and tranquility in the body, and the black and white qi moved around Jin Dan, and there was nothing abnormal.

Su Chen's divine thoughts probed in the sea of qi, trying to find the problem, but after repeated investigations, he didn't find anything wrong.

After a little thought, he decided to continue forging his sword.

The Divine Fire of the Heart had already disappeared on its own when the Black and White Qi broke in, and at this time, it was re-summoned by Su Chen to calcine the spiritual energy and reforge the sword soul. Because the aura in his body had already been refined, the process of forging the sword this time was very fast, and he only needed to gather the aura and calcine it with his heart fire.

However, as he expected, when the sword soul had just revealed its rudiments, the black and white qi rioted again, defeating his sword soul and destroying his golden pill by the way.

Su Chen couldn't help but want to scold his mother, and tried a few more times, but the result was the same, which made him extremely devastated.

The black and white qi was not under his control, he couldn't expel it if he wanted to, and with these two goods, he couldn't forge a sword at all.

Moreover, this situation is not recorded in the Sword Ancestor Codex.

After another attempt, Su Chen was no longer in a hurry to cultivate, he needed to analyze the current situation and find a feasible method.

The bamboo forest temporarily returned to calm, and Xiyue and Long Qingyan looked at each other, they really couldn't figure out the current situation.

Every time the sword qi and aura in the bamboo forest were in a frenzy, it was actually the moment when Su Chen's sword soul was destroyed, and as his body calmed down, the bamboo forest would also return to peace.

Su Chen sat quietly, pondered, and after a while, he had a plan.

The fragments of the golden pill were still connected by silk threads, and the black and white qi were still moving around the golden pill, and Su Chen attracted the fragments of the golden pill, but instead of gathering them, the fragments surrounded the black and white two qi, like a broken cocoon that was connected by silk to maintain its shape, and the black and white qi were hovering in the cocoon.

The heart suddenly burst into flames, not calcining Su Chen's aura, but calcining black and white qi.

"If you want to stop me from forging a sword, I will forge you into a sword!" Su Chen planned to do so.

The black and white two qi seemed to feel Su Chen's anger, and began to feel uneasy, scurrying around in the "cocoon" formed by the fragments of Jindan, but this cocoon seemed to be broken, but in fact it was like a cage, completely blocking the black and white two qi, and the divine fire of the heart was densely covered in the cocoon, chasing the black and white two qi and burning. Su Chen is also introducing the aura bit by bit, allowing the aura to surround the black and white qi, and with the help of the calcination of the heart fire, it is integrated into it.

The black and white qi became more and more violent, constantly impacting the cocoon, but the cocoon was unexpectedly flexible, and it was almost deformed by the impact of the black and white qi, but it just couldn't be destroyed. And Su Chen was determined to refine them, and poured all his strength into this place to fight against the black and white qi.

In this way, after an unknown time, the black and white qi gradually calmed down, Su Chen introduced his own divine thoughts into the cocoon, and used the power of the heart fire to enter the black and white two qi, and controlled it to turn into a sword shape and stabilize it under the calcination of the heart fire. However, the black and white qi themselves are incompatible, they are two qi, so Su Chen's divine thoughts are also divided into two, and they are divided into two, and the result is that there are two sword souls in his body.

This time, the process of forging the sword took longer, but after the black and white qi was controlled, everything went smoothly, and there were no accidents, which made Su Chen breathe a sigh of relief.

And after Xiyue and Long Qingyan waited here for three days, Long Qingyan repeatedly persuaded Xiyue to go back first, and he watched here day and night; Xiyue would come to see every day, but fortunately, after half a month, Su Chen returned to normal, and there was no such riot anymore.

What the other two friends didn't expect was that it was already mid-February when Su Chen woke up.

The snow had melted, the bamboo forest was verdant, and the wind was howling, when Su Chen opened his eyes, he was confused for a moment, especially when he saw the dilapidated land around him, he was almost startled.

"Yo, wake up?" Long Qingyan's voice came from behind him.

"Why are you here?" asked Su Chen when he turned around.

"You have to ask yourself what good things you have done!" Long Qingyan said angrily.

Su Chen was at a loss, how did he know that in the days when he was fighting against black and white, he could make his two friends sad. He looked around, it was night, and looked at the sky, a crescent moon surrounded by stars, and the heavenly river stretched like a silver ribbon.

"What time is it?" asked Su Chen.

"It's spring again. Long Qingyan replied.

Su Chen sighed: "Fortunately, there is no danger, and I successfully crossed this level." ”

Long Qingyan frowned and asked, "What happened?"

Su Chen said: "Go back first, I will inform you and Xiyue in detail." ”

Under the Tang pear tree, after listening to Su Chen's story, Long and Yue were shocked, this kind of strange thing is unheard of, unseen, it is simply a fantasy, but it really happened, and it was on their friends, so they couldn't accept it.

"And what about the result?" asked Xiyue.

"Look. Su Chen said, his right palm was spread out in front of him, and as soon as his mind moved, two sword qi, one black and one white, coiled out, turning into two sharp swords of the same color and hanging in front of the three of them.

"When the sword was formed, I withdrew my divine thoughts, leaving one wisp in black and white, and in this way, two sword souls were cast. Su Chen explained.

"Then aren't you going to refine two Dao swords in the future?" Long Qingyan said suspiciously.

"I don't know, I was also dizzy at the time, and I didn't think about it so much. Su Chen smiled bitterly.

Xi Yue said: "I'll talk about this later, what I'm most curious about is why the black and white qi want to destroy your sword soul." ”

However, Su Chen shrugged his shoulders, because he didn't know either, so he couldn't explain it to the two friends, so he could only leave it for later, if he could find out the origin of the black and white qi, maybe he would be able to know the reason.

After listening to Su Chen's words, Xi Yue was angry: "I said are you stupid? The sword soul is so important to you, you are so sloppy? You are not afraid of self-destruction by forging a sword with such an unknown source?"

Xiyue's words were almost shouted, Su Chen subconsciously covered his ears, Long Qingyan hugged Xiao Zi, and watched the play on the side, both of them looked very intriguing.

After being trained by Xi Yue for a long time but unable to refute it, Su Chen was aggrieved like a child, Long Qingyan came out at the right time to play a round and said to Xi Yue: "Okay, okay, I know that you are for his good, but things have happened, and there is no way to regret it, it is better to think about what to do in the future." ”

Xiyue glared and said, "It's his business, I don't bother to care!" After speaking, she left angrily, and Xiao Zi hurriedly chased after her.

Long Qingyan then asked Su Chen: "I don't believe you didn't think it through, so what are your plans?"

Su Chen replied as usual: "The sword soul has been completed, I can control it, don't worry about the backlash, there is no need to rush to cast the Dao sword, wait until you find out the origin of the black and white qi." ”

"Is there a direction?" asked Long Qingyan.

"Perhaps, it has something to do with me being framed. The black and white sword soul returned to Su Chen's body, his brows furrowed slightly, and his expression was different.

Xiyue went and returned, she didn't go far, and after hearing Su Chen say this, she immediately came back and asked him to continue.

The time when this black and white qi appeared was after Su Chen was infected by the evil qi in Daowu Palace. At that time, these two forces inexplicably appeared in his body, and they came out of the sea of his consciousness. In fact, he should be grateful for the black and white qi, because of the emergence of these two diametrically opposed and fighting forces, the evil qi could not completely erode his sea of consciousness, and he maintained a little sanity, and saw the death of the master and the mother and everything that happened afterwards.

And there is another thing that Su Chen himself doesn't know, when he was in the Qitian Mountain Range, he was poisoned by the black widow, and it was this black and white qi that saved his heart and brain at that time and kept him from dying, otherwise Xiyue would not have a chance to save Su Chen's life.

However, Su Chen spent more time forging the sword soul, and they were also the culprits.

"In this way, black and white should be your own strength, but you have been unable to control it, which is why so many things have happened. Xiyue said thoughtfully.

"So, it's not necessarily a bad thing for you to forge them into sword souls now, at least you can control them. Long Qingyan said, "Then your Jin Dan?"

Su Chen said with a smile: "Give it up, anyway, the Terran monks don't need to keep the golden pill in the first place, I just melted the golden pill in advance, and now the golden pill has been completely integrated into the sword soul, and since then I will only cultivate these two sword souls." ”

Concentrate on the sword, and only forge one sword in his life, although there is a difference here in Su Chen, Su Chen feels that this is not a bad thing. The path of the former sage can be learned, but it cannot be copied, he always has to step out of his own sword path, maybe the double sword soul is a beginning.

He is also confident that he can continue the path of sword cultivation and surpass the Sword Ancestor!
