Yang Hongqiu glanced at the dense Yin Spirits outside the formation and said, "Cheng Ling, you might as well introduce these Yin Spirits into the formation and use the Yin Qi to stabilize the formation." ”

Cheng Ling's eyes lit up, why didn't he expect it? There are so many yin and cold qi, just like the formation has been replenished by a powerful spiritual source, no matter how many yin spirits there are, they can't be broken in a short period of time!

He immediately took action and added another spirit attraction array in the center of the formation, as a general existence of the formation center. Sure enough, it didn't take long for all the yin qi stored in the spirit sealing array to converge, constantly enhancing the power of the Lost Trace Array and the Killing Array, and the Yin spirit inside died faster.

Yang Hongqiu said to Su Yi: "Concentrate on calming your energy, run the exercises, and refine your yin qi with all your might." ”

Su Yi agreed, where would he let go of such an opportunity, and hurriedly refined.

Cheng Ling sat down cross-legged, and the crazy yin and cold qi continued to pour into his body, and in less than a quarter of an hour, the yin and yang qi reached a balance. The color of the immortal power in the body has become half transparent, and it is generally milky white.

At this time, he knew that he could no longer absorb it, and any further down the Yin and Cold Qi would take over, and the Qi in his body would be out of balance again. But looking at the rich cold air in front of me, I really can't afford to waste it.

The divine sense swept over, and saw that Yang Hongqiu and Su Yi were refining with all their might. Yang Hongqiu's breath became more and more mellow, and he was obviously harmonizing the power of yin and yang in his body. Su Yi was different, his aura fluctuated for a while, as if he was impacting the Earth Fairyland.

Cheng Ling's eyes showed a hint of appreciation, this kid was full of courage, and he actually thought of using the cold qi to break through the realm. Not to mention, this method is completely feasible in theory, as long as the balance of yin and yang is well controlled, there is a good chance that it can be successful.

His mind flashed, the cold aura here was somewhat similar to the cold aura he felt in the Ice Prison of the Yunlan Sect back then. If he can fuse the Yin and Cold Qi with the Ice Technique, can it play a promoting role?

The ice system belongs to the mutation spirit root of the water system, but it is different in application and form, relatively speaking, the attack power and explosive power of the ice system are stronger, but the support and flexibility are not as good as the water system.

There is an explanation of the application of the Ice Pole Dao in the Eight Extremes Dao spells: Xuan is the extreme of cold, the underworld is the extreme of yin, and the extreme of yin and cold eventually becomes the extreme of heaven and earth. The "Xuan" in this is the meaning of ice, and it is literally explained that only by fusing the extreme of ice, the extreme of the underworld can the spell reach the highest level.

The experiment just now made him know that his Golden Pages Technique could absorb the cold qi here, but it was too slow to simply absorb the cold qi or ice spiritual power to improve his cultivation. The power of the three mutated spirit roots of ice, thunder, and wind is generally higher than that of the five elements spirit roots, but they also have a fatal flaw, that is, there are too few methods corresponding to auxiliary cultivation.

If you can combine the ice system with the cold qi, you can not only increase the cultivation speed of the ice spirit root, but also make the ice spirit power mutate again and fuse it into the power of yin and cold. It makes the spiritual power more powerful, more penetrating and explosive.

The mysteries of the monastic realm, like the human body, have not been fully studied thoroughly. Even in the 21st century, there are still many unsolved problems in the study of the human body. So, whatever the idea, it's possible to make it happen.

Intuitively speaking, the path of cultivation is divided into horizontal and vertical aspects, and if the balance of yin and yang is counted as horizontal development, then the cultivation of metal, wood, water, fire, earth, wind, thunder, and ice is vertical. The most basic requirement for multi-spiritual root cultivators is that the cultivation realm of each spiritual root must form a balance, and they can only reach a new peak by going hand in hand.

Perhaps the above eight spiritual roots are not enough to summarize, there are also attributes such as light, darkness, life, death, space and time between heaven and earth. But for the current Cheng Ling, among the eight attributes known, the weakest should be the ice system and the wind system.

If these two attributes can reach the same height as the other six, their own combat power will definitely have a qualitative leap. Therefore, he did not hesitate to try, mobilizing the cold qi in his body and absorbing the cold qi in the spirit sealing array, and the two constantly collided and fused in his body.

It was like stepping on a rocker, constantly adjusting the spiritual balance between the two. After a long time, the two spiritual powers finally began to merge into a thread. Ecstasy in my heart, make persistent efforts, and continue to let the energy of the two merge with each other.

At this time, he also discovered that the Yin Spirits and those red-haired and green-haired ghosts produced Yin Cold Qi was much higher than that of Yin Spirits, at least ten times as high.

He didn't know that most of the Yin Spirits and those red-haired and green-haired ghosts were born in the Netherworld, and they were born with Yin Qi, so it could be said that the whole was a collection of Yin Qi.

The Yin Spirit, on the other hand, is a person who has just died in the mortal world or the fairy world, and is transformed by the influence of the Yin Qi of the Netherworld. Because since a person is dead, his own three souls and seven spirits are much less, and he often loses part of his soul, coupled with the strong yin qi of the netherworld, it is easy to be affected and transformed.

Therefore, most of the yin and cold qi absorbed by the three of them is the original yin and cold qi of the netherworld, but this is also of great benefit to them, after all, the yin qi of the yin soul is much purer, although the yin spirit is less soul, but after all, there is still a part of the remnant, absorbing too much, it will lead to the soul mixture, which will affect the sea of knowledge.

Yang Hongqiu was in need of this pure soul power, and under the absorption, the soul in his mind began to grow significantly, forming an overwhelming advantage over the remnant soul.

Su Yi has gained a lot, this kid is single-mindedly impacting the Earth Fairyland, the environment in front of him is like a sealed cold qi space, and in the past few months of continuous killing, his own cultivation precipitation has reached its peak.

After absorbing it like this for two days, the barrier of the Earth Immortal Realm was finally broken through, and the strong cold qi surged, and a whirlpool finally formed on the top of the head, pouring down. Although this whirlpool cannot be compared with Cheng Ling and Yang Hongqiu, it has finally reached the Earth Fairyland.

He couldn't help but laugh.

Cheng Ling said angrily: "Don't be too happy, hurry up and refine those yin and cold qi, how much can you improve, and then find a way to adjust the balance of yin and yang qi after leaving the netherworld." ”

Su Yi's heart froze, and he was not happy at the moment, so he hurriedly calmed down and hit the future realm again.

Time passed slowly, and soon another ten days passed, and there were fewer and fewer yin spirits in front of the gate, and Cheng Ling successfully raised his cultivation to the peak of the Nine Star Land Immortal Realm through the combination of yin qi and cold qi. Yang Hongqiu is not bad, he is already at the critical point of coming to the Heavenly Immortal Realm.

In fact, it has been hundreds of years since she reached the Nine Star Land Immortal Realm, and if it weren't for the head disease, she would have been able to break through in less than a hundred years with her understanding. Therefore, most of the absorption during this period of time was still the cultivation of the living soul, and now it feels that the remnant soul in the soul is no longer a threat.

Su Yi gained the most, from the Nine-Star Xuan Immortal Realm to the Three-Star Earth Immortal Realm, he was already a high-end monk in the Star Realm. However, at this time, he didn't dare to absorb a large amount of Yin and Cold Qi anymore, but began to cultivate steadily.

Besides, there weren't many Yin Spirits left in the formation, only at the edge of the gate, there were still a few strange-shaped Yin Spirits, and they were all shocked by the scene in front of them, in such a short period of time, they actually killed hundreds of thousands of Yin Spirits.

Cheng Ling let out a long breath, opened his eyes, and with a wave of his right hand, several formation flags on the formation center were withdrawn from his hands, and the formation that enveloped the three of them slowly landed, and his figure appeared again.

But as soon as he appeared, he secretly complained. In front of the bone gate, there were two green-skinned ghosts standing on the left and right sides, and those two ghosts had a strong aura, and they felt even more above the Holy Lord.

Yang Hongqiu and Su Yi also found out, and they didn't dare to move for a while. Cheng Ling's sense swept away, and when he saw that the Lost Trace Formation had not all dissipated, he transmitted his voice and said: "Master, Su Yi, while the Lost Trace Formation is still there, hurry up and rush into the gate, be quick!"

The two of them were startled, and they moved instantly, and their bodies almost turned into a bolt of lightning and rushed towards the bone gate. Cheng Ling deliberately left the two of them in one position, and his divine sense always paid attention to the changes in the ghosts on both sides.

Just as Yang Hongqiu and Su Yi passed through the portal, and Cheng Ling felt a trace of resistance in front of him, the green-skinned ghost on the left smiled coldly at him, grabbed his right hand, and said, "Stay!"

A huge suction force came from the side, Cheng Ling's face changed greatly, and he didn't hesitate to sacrifice the Dragon Ling Sword, and slashed it down with a sword, instantly splitting the suction in half. But the claw shadow of the green-skinned goblin on the right also came behind him.

Cheng Ling's back didn't have time to react at all, so he could only turn sideways to avoid the vital point, and his back was hit hard by the claw shadow!

A mouthful of blood spurted out of his mouth, and he resisted stubbornly, and planned to rush into the portal with his strength. It's just that soon, a chill ran down his spine, and a devastating aura came from behind him, and even his soul felt a little trembling!

"Trespassing into the Hell Realm and killing so many Yin Spirits, you should go to the Infernal Hell to suffer for ten thousand years!"

The divine sense swept over, and I saw that the person behind him was dressed in a bright red robe, wearing a gray crown on his head, his face was cold, and his right palm was slapped out, and the sharp palm wind killed his back.

Cheng Ling was so frightened that he used the Shadowless Thunder Void Body Method to the limit, and then took out a highest-grade divine talisman from the ring and slapped it on his body, and within a fraction of a centimeter, he crashed into the bone gate.

But even so, he was swept away by the palm of the red-robed strange man, and the blood in his mouth spurted wildly, and he fell to the ground as soon as he entered the bone gate.

Yang Hongqiu and Su Yi hurriedly rushed over and held him up.

Cheng Ling's figure was stunned, and he suddenly felt that the breath in the space was very familiar, as if he had met it somewhere. When he opened his eyes, he immediately found that there were turquoise flames everywhere in front of him, and the scorching heat and cold of the flames in the entire space were mixed together.

Looking at the inside of the flames, bodies like humans and monsters were everywhere in the flames, and they were being scorched by the turquoise flames. They kept twisting their bodies, and their mouths let out a series of terrible howls, it was like a human purgatory!

After only a few glances, Cheng Ling suddenly felt a sharp pain in her eyes, and couldn't help but spurt out a mouthful of blood again, leaving two bloody tears in her eyes, and slowly fell down with her head tilted, I don't know if I live or die!
