Just as Ning Caichen and the others were talking, they suddenly felt that the ghost qi around them suddenly stagnated, and they didn't have time to react.

It felt like a black veil was enveloping several people. Then the voice of Xiyue sounded in my ears.

"Empty your mind and don't resist. ”

Through this period of getting along, Ning Caichen has gradually become familiar with Xiyue, and knows that Xiyue will not harm him.

Hurriedly said to Yan Chixia and the others beside him, who were already preparing to resist, "Do it." ”

Although Yan Chixia and the others have not gotten along with Xiyue because of their coma, they are not very familiar with each other. But he still believes in Ning Caichen unconditionally.

At this time, when he heard Ning Caichen's words, he hurriedly calmed down the vitality that had been lifted in his body.

The next moment, I saw that the black yarn suddenly rolled, and I saw a black in front of me. Then the mind becomes chaotic.

I don't know how long it took, but the light finally returned to the eyes of several people.

However, the foot has already changed positions. The original shouts of battle have disappeared, and in its place are the towering black trees that can be seen endlessly, and the strange red clouds that obscure all vision.

"This is?" Looking at the black wood forest filled with red clouds, Ning Caichen and the others couldn't help but widen their eyes.

"Stygian Forest. For some reason, Xiyue's face was a little pale at this time, and her tone of voice was not as crisp and pleasant as before, and she looked weak.

Maybe the vision was too shocking, so Ning Caichen didn't notice Xiyue's expression at first, but after listening to Xiyue at this moment.

Subconsciously took a look, and found that Xiyue's face was unusually pale, and there was a line of blood hanging from the corner of her mouth.

"You're hurt. Ning Caichen frowned slightly

"It's okay, when I brought you out just now, I had a fight with those ghost kings, and my body was just a little weak, and it won't take long to recover. Xiyue waved her hand

After speaking, perhaps because he was afraid that Ning Caichen would be worried, he added: "This is also the reason why I was injured before, and only three percent of my cultivation is left, if it is when my cultivation is completely victorious, it will be five ghost kings, and it will be destroyed with a wave of my hand." ”

Although Xiyue said it easily, it was like a huge wave in the ears of Ning Caichen and others, stirring Ning Caichen's heart for a long time.

Because as far as Ning Caichen knows, the cultivation of these five ghost kings has already reached the realm of the ghost kings of the four directions, that is, the realm of earth immortals among the monks. Among them, the cultivation of the Immortal Ghost King has reached the late stage of the Quartet Ghost King, and he is only one step away from the realm of the Ghost Venerable that is juxtaposed with Xuan Xian.

At this moment, in Xiyue's mouth, it was so vulnerable. Could it be that Xiyue has already entered the realm of the Xuan Immortal where the spirit and body are one.

By the way, since Ning Caichen saw Xiyue for the first time, he found that Xiyue's body was a little strange, and now that he thinks about it, it turns out that it is because he sees Xiyue's body.

And the reason why I have never doubted it is because once I enter the realm of Xuan Immortal, my physical body will transform into a state of mystery and mystery, almost no different from the primordial god.

Thinking of this, Ning Caichen couldn't help but ask, "Could it be that your cultivation has already entered the Xuan Immortal Realm." ”

Hearing Ning Caichen ask if Xiyue had entered the Xuan Immortal Realm, Yan Chixia and the others' eyes suddenly widened, and they looked at this side with a curious expression.

Because although he has known the prestige of Xuan Xian for a long time, he has never seen a truly living Xuan Xian.

After being silent for a long time, Xiyue finally nodded slowly. But after nodding his head, he shook his head again.

Although Xiyue didn't speak, Ning Caichen already knew what Xiyue meant.

Xiyue nodded to mean that Ning Caichen guessed well, he had indeed entered the Xuan Immortal Realm, and shaking his head meant that Xiu Wei had surpassed the Xuan Immortal Realm.

After understanding what Xiyue meant, Ning Caichen didn't ask again, because after passing the Xuan Immortal Realm, he had already entered the calculation of the Heavenly Dao, if he didn't have any precautions, he might be contaminated with unnecessary cause and effect if he didn't say a word well.

Ning Caichen didn't want Xiyue to be contaminated with those inexplicable causes and effects because of his curiosity.

Although Yan Chixia and the others on the side didn't understand what Xi Yue meant by nodding her head for a while and shaking her head for a while, they saw that Xi Yue was reluctant to answer, so they could only take their curiosity back.

After coming back to his senses, Ning Caichen shifted his attention to this dark wood forest again.

Turning his head to Xiyue beside him, he asked

"You just said it was the Stygian Forest"

Xiyue nodded and said, "Yes, this Qingming Mountain is divided into two levels, the lower level is the Green Wood Forest, which is mainly composed of the Green Wood Devil, and the upper level is the Dark Wood Forest, but it is composed of the Dark Wood and the Blood Demon. ”

"The red clouds you see in front of you are the legendary Blood, and these black trees are the legendary Stygian Wood. ”

After Xiyue finished speaking, Ning Caichen hadn't spoken yet, and Yan Chixia on the side touched the black giant wooden road on the side with a bright look

"It turns out that this is the legendary dark wood, if you cut two or three and take it home to make a tool, then it won't be twice the result with half the effort to subdue demons and eliminate demons in the future. ”

Legend has it that the wood grows in the land of the underworld and the extreme yang, and is nourished by countless pure yang qi and ghost qi, and the wood contains a large amount of pure yang qi and ghost qi.

Pure yang and yin, ghost spirit macro method. Once made into a magic weapon, it not only has a lethal restraint on the yin and evil things that are yin by nature, but also can increase the spells cast by the owner of the magic weapon.

Therefore, in the eyes of the monks, the dark wood is a rare refining thing.

As far as Yan Chixia knew, there was a demon-slaying sword made of thousand-year-old dark wood in the Qingcheng Mountain.

However, although the wood is good, it is very rare because the formation conditions are too harsh.

Because the underworld is the place where the yin energy is the heaviest in the Three Realms, it is not an exaggeration to say that it is the place of the most yin, and it is even more difficult to find a trace of yang energy in the underworld than to find a needle in a haystack.

Not to mention the towering trees nourished by yang energy, which is even more difficult.

And in the underworld, although there are many ghost qi, the ghost spirit qi is rare. Because the qi of the ghost spirit is dissipated by the true spirit of the master of the ghost king realm, and it is transformed after death.

The qi contains spirits, and if it is used properly, it is even a few points more powerful than the dense immortal qi in the sky.

Therefore, even in the vast and boundless underworld, this underworld wood is extremely rare. As far as Yan Chixia knows, at present, there is only one place in the underworld, and that is Luo Fengshan, the dojo of the Emperor of the Northern Yin Dynasty.

However, with the means and status of the Northern Yin Emperor, not to mention that Yan Chixia now only has the cultivation of the Yang God Realm, if he does not have the permission of the Northern Yin Emperor, even the master of the Nine Heavens Xuan Immortal Realm may not be able to take down a single plant from the Dao of the Northern Yin Emperor.

Even the legendary Golden Immortal Master is no exception.

So there is such a legend among the monks, although the Stygian Wood is good, it is just a legend.

It is said that the demon-subduing sword in Qingcheng Mountain was also carved by a branch broken off when the Heavenly Master Zhang Daoling achieved the Golden Immortal Dao Fruit, returning from the underworld to teach the Fa, and passing by Na Luo Feng Mountain.

However, it is said that after the incident, Zhang Daoling was in retreat for more than 300 years.
