Suddenly, Shi Chiyan's face turned a little weird, and before Yu Lewei could ask, two ghostly burly figures had already appeared beside them one after another, and they were Ma Khan Blood and Niu Sanshan.

After appearing, Niu Sanshan just shook his head and panted repeatedly, while Ma Khan and Blood sat next to the two of them, and said with a smile: "What you are discussing, in fact, I have been thinking about it all this time, boy, have you ever thought that maybe you were a big person in your previous life." ”

"Big shots?" Shi Chiyan was slightly stunned, and Ma Khan nodded and said, "That's right!" That's why you can have so many adventures, all the way to the sword, the realm is also climbing step by step, maybe it's all because of the legacy of your luck in your previous life. ”

"Then why can't Senior Sister completely dissolve the negative energy, but I can?" Shi Chi Yan asked.

Niu Sanshan sneered: "That's not simple, either this exercise was originally created according to your true spirit characteristics, so only you can fully use it, or you actually have something in your body, and it helps you dissolve the remaining negative energy." ”

The so-called true spirit is the consciousness of living beings, ordinary living beings will only have consciousness, so after their death, the true spirit is separated from the physical body, according to the image of the living and the illusion, if it is not protected in time, then the true spirit will either dissipate reincarnation, or fall into the ghost world, muddy, until it absorbs enough yin qi and steps into the realm of ghosts, in order to recover the memory of the previous life.

For example, the so-called cultivation of the soul by the ghost path monks is actually the cultivation of the true spirit, the imitation of the true spirit into the soul of the heart, and then the yin soul, the yang soul and even the soul body.

Although each person's true spirit seems to be a small dot in essence, in fact, it contains hundreds of millions of differences, and according to each person's growth experience, the internal structure of the true spirit is also very different.

This is also the reason why some people are suitable for cultivating fire-based exercises, and some people are suitable for water-based exercises.

As Niu Sanshan said, perhaps this "Soul Yan" was originally created by Shi Chi Yan in his previous life according to his own true spirit, so the most suitable for this exercise is also Shi Chi Yan.

"Of course, if you want your true spirit to be in line with this exercise, there is another way," Ma Khan snorted and looked at Yu Lewei with a lewd smile, "that is the ...... of intercourse."

Boom! Annoyed and angry, Yu Lewei slapped Ma Khan's bloody nose and slapped the horse's face alive.

Seeing Shi Chi Yan pretending to be sitting next to him seriously, Yu Lewei became more and more embarrassed, and snorted: "Can you guess the identity of the junior brother in his previous life?" ”

Niu Sanshan shook his head: "The ghost knows, throughout the ages, there have been countless strong people born in the underworld, just with this secret method to dissolve negative energy, how can I guess his identity." ”

At this time, Ma Khan was flying back with his nose covered, and when he heard a few people talking, his eyes flashed a little weird.

When the fish turned into a dragon and took him away, Ma Khanxue had seen the purple-haired man, among the Seven Realms and Liuhe, there was almost only one person who could have this hair color, and he was dressed in a Tang robe, and his momentum was like a dragon.

And that person happened to have a life-and-death friendship with a former giant in the underworld, and he vaguely remembered that the giant of the underworld seemed to have disappeared back then, so he said......

Ma Khan shuddered suddenly, he found for the first time that it was not a good thing for his brain to be too smart, at least he vaguely guessed the identity of Shi Chi Di, and the fear in his heart was more than surprise.

That's a game beyond the limit of the seventh order!

Shi Chi Yan and the others did not notice the abnormality of the horse's sweat and blood, at least from a human perspective, there was no change in the expression of a horse's head.

After taking Ma Khan Blood and Niu Sanshan back to the Soul Mansion, Shi Chi Yan and Yu Lewei Imperial Sword traveled quickly, and soon came to the Yin Yang Sect.

Shi Chi Yan originally wanted to go to the Yanhu Purple Sword Sect, but Yu Lewei felt that it didn't matter if she usually cultivated, but when taking spiritual objects, it was best to stay in a place where the yin qi was too heavy.

At this time, it was already more than eleven o'clock in the middle of the night, and after the two landed at the entrance of the village, they first went to meet the fish dragon, and then the two entered the white tower with a warrant.

With the current strength of the two of them, the Taiyin Qi of the previous layers could no longer sustain their cultivation, so Shi Chi Yan and Yu Lewei stepped down to the seventh layer, and the Yin Qi in this layer was so thick that it formed a thick fog, and ordinary people would erode the five internal organs and turn into a puddle of muddy water just by breathing.

The further down, the area of each cave will gradually decrease, the area of the seventh layer is only less than a hundred square meters, Shi Chi Di and Yu Lewei in order to avoid mutual interference, sit on both sides of the cave, and then start refining the water of the River Styx.

Taking out the jade bottle, Shi Chi Yan found that even if the jade bottle was sealed with the Prisoner Seal in advance, the breath of the Styx water still penetrated the seal and emitted it, if he waited for a few more minutes, it was estimated that the bottle would be corroded by the Styx water.

Obviously it has been refined by the secret method, but it still has such a terrible corrosiveness, Shi Chi was secretly frightened, and then took out a drop, his breath slowly flattened, and his mind rolled up that drop of Styx water, incorporated it into the soul mansion, and refined it with strong soul power.

When the Styx water was put into the jade bottle before, he didn't feel it, but after Shi Chi Yan lifted it with his mind at this moment, he suddenly felt heavy like a mountain, if it weren't for the fact that his soul body was already heavy, and he had an adventure when he went to Beijing, he was afraid that he couldn't hold up this Styx water.

The water of the River Styx is in the same vein as the Underworld's original energy, the Underworld's Origin Energy, or in other words, the difference between the liquid state and the gaseous state.

Once the ghost path cultivator has cultivated to the peak of the palm sea, when he has survived the heavenly tribulation and ascended to the underworld, he will accept the pursification of the underworld, and wash away all the negative energy brought by the original ghost power, so that he can be reborn and adapt to the environment of the underworld.

At this moment, his mind enveloped the water of the River Styx, and when he died, he felt a quiet and distant breath penetrating his heart, that breath was not strong, it could be said that it was not much different from his usual state of rushing and laziness, but inexplicably, it was this quiet aura that made people completely unguarded, but it could quietly erode the minds of others.

The ghost qi is violent, making people extreme and perverse, while the dark qi is calm, making people wash away all joys, sorrows, and sorrows, like a puppet without three nothings.

Feeling the leisurely breath that belongs to the water of the River Styx, Shi Chi Di almost instinctively runs "Soul Evolution" to fight against the erosion that makes people seem to abandon all emotions.

However, I don't know why, even in this extreme confrontation, Shi Chiyan couldn't help but feel a sense of familiarity, as if he remembered something, but it didn't seem to be.

In the trance of consciousness, Shi Chi Di did not realize that his purple-gold soul body was faintly exuding some fluctuations, so that the erosion of the Styx River water was always blocked from Shi Chi Di's soul body, and it was only decomposed by heavy soul power, and it was integrated into the soul body according to the "Soul Refining Chapter", and finally disappeared.

Shi Chi Di didn't realize that after the Styx water submerged into the soul body, it didn't actually increase the soul body, but it was as if it was swallowed by some invisible thing.

Drop by drop, half an hour later, Shi Chi Yan had already refined six drops of Styx water one after another, and then opened his eyes slightly blankly.

He didn't know what was wrong with him, he actually became inexplicably drowsy when refining the water of the River Styx, and he was stunned for a moment, and Shi Chi Yan suddenly shuddered, and quickly looked at his body, for fear that he would be eroded by the water of the River Styx and cut off part of his emotions.

However, when his mind swept back and forth in the soul mansion several times, he was surprised to find that he had not changed by half a point, the soul body had not changed, the soul sea had not changed, the soul seal had not changed, and the weapons such as the Evil Heart Sword, the God Slayer, and the Liuhe Mirror had not changed.

"Did you steal it?" In a daze, Shi Chiyan subconsciously asked.

Ma Khan rolled his eyes, and Niu Sanshan said angrily: "Guan Laozi's!" ”

Shi Chi Yan also said casually, and after being scolded, he smiled sneeringly, although he said that he had not changed at all after refining the water of the River Styx, but recalling the feeling when he had just refined, a thought inexplicably flashed in Shi Chi Yan's heart.

The ghost is ugly and makes people manic and violent, but if it is good, it makes people emotional.

It is said that it is good to make people calm and steady, but to say that it is difficult to hear, it makes people lack emotion.

Touching his eyebrows, Shi Chiyan muttered, "Could it be that these two should be one?" ”

"Another patient of 'ghost and hell unity'."

In the Soul Mansion, Ma Khan Blood heard his whisper, and couldn't help but let out a sneer: "Boy, your idea was prevalent in the world tens of thousands of years ago, but after countless 'sages' research and attempts, it was finally found that ghost qi and underworld qi are completely two different structures of energy, if you want to combine them, maybe Xuanhuang and Huang Qi can do it!" ”

"Xuanhuang Erqi?" Shi Chi Yan looked puzzled, and Ma Khan didn't bother to explain: "Anyway, you don't have a chance at all." ”

Shi Chi Yan smiled, and didn't ask, just silently recalled the feeling just now, and only smiled with relief after a while, although it was said that it failed to increase the foundation, but in any case, feeling the subtlety of the dark qi in advance is also of great benefit to the ascension to receive the purification of the dark qi in the future.

He was thinking there, and suddenly felt a lot of heat in front of him, and a soft snort from Yu Lewei sounded in the depths of the dense fog.

Just before rushing to the other side of the cave, Shi Chi Yan had already seen the dense yin qi fog in front of her quickly thinning down, and when she looked closely, she saw Yu Lewei sitting cross-legged on the ground, surrounded by infinite black flames, constantly seeping into her body, and constantly expelling outward, as if circulating inside and outside.

"What is this?" Shi Chiyan was stunned when he saw this, and Ma Khan was surprised: "I'll strangle it, this woman is also fierce, right?" It hasn't been long since I broke through to the primary ghost king, and this is about to break through to the intermediate ghost king again? ”

"Senior sister is about to break through again?" Shi Chi Yan was pleasantly surprised, and at this time he also woke up to the fact that the black flame surrounding Yu Lewei was the so-called Heart Demon Tribulation Fire.

If the ghost path monk wants to completely form the soul body, he must go through the four-hearted demon tribulation fire of the soul tribulation period, incinerate all the shackles that all the fetters have turned into, clarify the mental obstacles, and comprehend the obsession, so that he can truly turn the void into reality and step into the true form stage.

Yu Lewei had just broken through to the early stage of the Soul Tribulation not long ago, and she didn't expect that the six drops of Styx water would help her so much this time, causing her to trigger the second level of the Heart Demon Tribulation.

Even if there is no calamity, Yu Lewei's qualifications can be said to be demonic, and after reuniting with Shi Chi and establishing a relationship, the only obsession in her heart has been resolved, so although the black flame is raging at the moment, the situation is not critical, as long as there is enough time, she can resolve the calamity fire by herself and be promoted to the middle stage of the soul tribulation.

Thinking of this, Shi Chiyan also sat down, looked at the black flame with interest, carefully felt the mystery contained in the black flame, and finally subconsciously stimulated the mirror soul seal, wanting to reflect the heart demon calamity.
