Mu Xuan glanced at him indifferently, his fingers were a little bit apart, and he instantly sealed the true qi in the bodies of several people, and with a wave of his robe, he threw them into a dark crack in the abyss, which was densely covered with countless passages, I am afraid that even the Tongyou Snake clan, who are the head snakes of the earth, will not be able to completely find out where each passage leads, seal these guys and throw them inside, whether they are dead or alive depends on their own luck.

"Let's go, let's go to the cold pool first."

After solving these people, Mu Xuan didn't stay long, and with a wave of his palm, he took the lead in storming the depths of the ground, and behind him, Xiao Yu and Yan Na followed closely.

In the underground world, the terrain is extremely complicated, but fortunately, Mu Xuan and the others came out this time, they had already prepared well, and naturally they also had a detailed map, so in less than an hour, they arrived in the underground world, and along the way, they also passed through the demon snake tribes, and after about half a day, they finally arrived at the base camp of the snake clan, the snake valley.

The Snake Valley is the headquarters of the Snake Clan, and it is also a holy place in the minds of many snake tribes, and as a holy place, the defense of this Snake Valley is naturally extremely strong, even ordinary demon snakes cannot enter it.

"It is worthy of being one of the three major races in the demon beast world, and in this mountain range, it is really as strong as a cloud."

On a mountain peak outside the Snake Valley, Mu Xuan and his party appeared, Xiao Yu looked at the mountain range in the distance and sighed in a low voice.

Mu Xuan smiled, looked at the depths of the leyline, and said: "The cold pool of the dark water is in the depths of the leyline, but there are many powerhouses hidden in this leyline, among which there are even powerhouses of the half-saint rank, if it is alarmed, it will be a little troublesome, so you try to restrain all the breath." ”

"Hmm."

Hearing this, Xiao Yu and the others also nodded, the strength of this Ghost Snake Clan is not weak, and now it is even deeper into the other party's base camp, if it is discovered, even if Mu Xuan has the strength of a martial saint, it must not be too easy.

"Hula!"

With a wave of Mu Xuan's robe, the surrounding space quickly distorted, and the bodies of everyone were tightly wrapped, and as soon as the space shook, everyone's figures disappeared strangely.

Today's Mu Xuan is already a pinnacle existence on this continent, and the power of space is used perfectly, and even he is enough to walk in Jiaolong Island, although there are three people with him now, it obviously does not constitute much consumption for him, so he shuttles through the space all the way to the depths of the Snake Valley, and does not attract any special attention halfway.

However, as he approached the depths of the Snake Valley more and more, Mu Xuan could also detect that the aura of the strong man in it was getting stronger and stronger, and occasionally once or twice, there were actually some doubtful spiritual perceptions swept from the space where he was hiding, thinking that he was a little perceptive, but fortunately, this awareness did not expose Mu Xuan and his party.

With the help of the ability to reach the sky, Mu Xuan narrowly avoided the induction of many strong people along the way, and finally quietly entered the depths of the Snake Valley.

In the extreme depths of the Snake Valley, there is a huge dark deep stream, this deep stream is a hundred zhang wide, bottomless, an amazing cold air, like a wind, constantly roaring up from its depths, ordinary strong people just stand here, that is, there will be a feeling of freezing in the blood and even martial arts in the body.

At the bottom of this deep cave, there is the hidden holy pool of the Snake Clan, the Ten Cold Pools, and the goal of Mu Xuan and others.

Beside the deep stream, there is no defense, because everyone understands that the cold and cold winds that constantly roar out of the deep stream are the most natural guards, and in the face of these winds, even the powerhouses of the Martial Sect rank dare not go deep easily.

"Whew!"

When this cold wind hung non-stop, the space here suddenly distorted slightly, and several figures slowly emerged, naturally Mu Xuan and his party.

Appearing, Mu Xuan glanced at the dark abyss, smiled slightly, did not stop, the sleeve robe waved again, and the rich spatial power directly wrapped everyone, breaking through the extremely cold Gangfeng and sweeping into the bottom of the dark abyss.

The deep stream was extremely deep, even at Mu Xuan's speed, it was about ten minutes before he could see the ground of the deep stream, and when he approached the ground, an extremely large cold pool not far away was also included in his eyes, and the kind of cold aura that was enough to freeze the bull qi in the human body diffused from it.

The cold pool is extremely huge, and the lake in the cold pool is dark, but in this darkness, there seems to be a trace of blood-like color, and a trace of light yellow mixed with a light blood of airflow, constantly seeping out from it, and finally rising up, whistling into the sky.

"This is the legendary cold pool."

Looking at the dark cold pool, Mu Xuan also breathed a sigh of relief and slowly approached, and as he got closer and closer to the dark cold pool, he could feel a faint cold power constantly drilling into his body.

"It's too cold here for even those who pass through the snake to endure it for a long time, so except in special circumstances, no one usually comes here, which gives us plenty of time." Yanna said softly, she was far away from the cold pool, and the cold power there, even she felt extremely uncomfortable.

Mu Xuan nodded, his footsteps finally stopped beside the cold pool, squatted down, his palm touched the lake, and suddenly he heard a sneering sound, and a dark ice crystal climbed up along his arm.

"It's really amazing, no wonder even my father said that he couldn't go deep into the bottom of the cold pool."

Seeing that the cold power in this cold pool of secluded water was so terrifying, Mu Xuan was also slightly startled, and the blazing flames in his body rose up, and finally seeped out, quickly melting those ice layers.

"Xiao Yu, I will first enter the bottom of the cold pool to obtain the true yin blood crystal, and after I succeed, you will enter the cold pool again, and I will help you protect the Fa." Mu Xuan shook his palm, turned his head, and said to Xiao Yu who walked to his side, among the few people here, he and Xiao Yu were able to approach Hantan, the former was because of his strength and Dacheng's fire, and the latter was naturally because of his physique.

"Well, be careful, and if you really can't do it, go back." Xiao Yu nodded slightly, and said with some solemnity, the cold power of this secluded water cold pool is too terrifying, it is hard to imagine that there will be such an extremely cold place in this heaven and earth, at the beginning, she was a little skeptical that Mu Yu said that this place could allow her to completely control the source of the wood spirit, but now that she sees it, maybe there is really such a possibility.
