All the core disciples jumped down from the dragon boat one after another, frowning and looking around the valley, there was no sign of any aura here, but the yin qi was very heavy.

Doesn't it mean that the Spirit Water Pool is in an abandoned spirit stone mine, even if it is abandoned, you should be able to feel some aura...... Many of the children thought to themselves, and they were quite puzzled.

Lei Fengxing jumped down from the dragon boat in the last one, he played a spiritual decision, made the dragon boat smaller, and put it in the storage bag on his waist, and then said lightly: "Let's go." ”

When he had finished speaking, he ignored the crowd and strode towards the front of the valley.

The children were full of suspicion, but they didn't dare to ask, so they had to follow him.

Although this valley is gloomy and cold, all the core children of the Lei family are here, there are more than 20 people, and they are all young people, and they are full of spirit, so after walking for a while, although they still feel cold, they don't feel so gloomy.

After a while, everyone walked to the end of the valley, and in front of them was an extremely steep mountain, and under the base of the mountain was a huge cave with a width of tens of meters.

This cave is unfathomable, and there is no end in sight from the outside, and there is a deep and cold aura coming from the inside.

Lei Fengxing did not hesitate, and led everyone to stride towards the cave.

As soon as he entered the cave, the light dimmed, and the cold meaning suddenly became stronger, and several core disciples who were only in the middle stage of the spirit body couldn't help but shudder.

As they marched deeper into the cave, the light became dimmer and the cold atmosphere became heavier and heavier, and many of the disciples even began to use spiritual power to warm up.

"Sect Master Lei, is this the place where the Spirit Water Pool is located, how come you can't feel the slightest bit of aura?" a core disciple couldn't help but ask.

Lei Feng didn't look back, and said lightly: "If you think it's not, you can go back by yourself." ”

The core disciple ate a nail, and his face immediately turned red.

As if he also felt that his attitude was a little stiff, Lei Fengxing stopped and explained, "The Spirit Water Pool is ahead, but if you want to get there, you have to pass through this cave. Because the aura here is barren and the yin qi is condensed all year round, it will feel very cold, and there may even be some low-level yin spirits or negative spirit beasts, but these yin things are only a threat to mortals, but they have little effect on us, so don't worry. ”

Hearing his explanation, all the core disciples were relieved. Thinking about it, compared to such a big opportunity as the spiritual water pool, this cold breath is nothing.

Thinking of this, everyone's spirits couldn't help but become invigorated again.

Xu You frowned slightly, he felt that Lei Fengxing was a bit of an understatement. The yin qi here is so heavy, there shouldn't be only such a threat.

And after entering the cave, Xu You had a feeling as if he was being peeped at, as if something terrible was secretly watching them.

He didn't speak, but he was secretly vigilant in his heart, releasing his spiritual consciousness and scanning the front and surroundings at any time.

The other core disciples also released their spiritual senses one after another, because the light in the cave was getting darker and darker, and they couldn't see anything clearly with the naked eye.

No one noticed that not far behind them, a ghostly shadow appeared silently, watching them go away.

Then, like a wisp of smoke, the ghostly shadow sank into the cold stone wall of the cave, leaving a hideous and terrifying face, and slowly disappeared.

After a while, everyone had walked seven or eight miles away, but the cave seemed to be endless, and they didn't know where the road ended.

The terrain of the cave has been going down, and after walking for such a long time, it is estimated that it has entered the depth of the ground for at least a few hundred meters.

Moreover, the road in the cave is very tortuous, and there are many forks and other caves in it, either the black hole is unfathomable, or it blooms gloomily with a cold gray mist, which makes people feel frightened.

Fortunately, Lei Fengxing seems to know which way to go, and every time he encounters a choice, he does not hesitate, and the children don't have to worry, they just need to follow this Lei Hall Master closely.

"Ahh

Everyone was taken aback, thinking that they were threatened, they all bloomed their spiritual power and put on a vigilant posture.

"What's going on?" Lei Fengxing's face changed and he strode over.

The young woman's face turned pale, and she pointed to the cold and moist cave wall and said, "I just saw a ghostly shadow passing in front of me, and then it ...... It went inside, and it had a terrible expression that scared me to death. ”

Her tone was frightened, obviously frightened just now.

Everyone looked at the stone wall, only to see that it was cold and damp, secreting countless dewdrop-like droplets, which seemed to be normal, how could there be any ghostly shadows, and they couldn't help but look at her suspiciously.

Seeing this, the young woman's brother knew that everyone didn't believe in herself, and couldn't help but be anxious and angry: "I really saw it, I didn't lie to you!"

Lei Fengxing looked at it for a while, but he didn't see anything unusual, and frowned: "Maybe you are dazzled, you have to stay calm here, otherwise the yin qi will enter the body, and it will be easy to hallucinate." ”

"I'm not hallucinating...... the young woman was about to argue, but Lei Fengxing had already turned back to the front of the group and walked forward again.

When the other disciples saw that Lei Fengxing said the same, they all looked at her with disgust, and hurriedly strode to follow.

The young woman patted her head in frustration, wondering if she had just been dazzled.

Among all the children, only Xu You's face changed slightly.

His spiritual sense is incomparably powerful, and his children can only see beyond the stone wall, but his spiritual sense can penetrate into the stone wall.

Less than a few feet inside, Xu You spotted the ghostly shadow, which was like a terrifying creature made of mist, extremely hideous, and it made people feel chills when they looked at it.

And this ghostly shadow can move freely within the stone wall, completely unrestrained.

As if sensing that he had been discovered, the ghostly shadow quickly retreated, and at the same time showed Xu You an unusually terrifying expression, as if it was about to devour people.

Xu You walked forward with everyone, there was no abnormality on the surface, but the spiritual sense followed the ghost shadow and continued to probe into the depths of the stone wall.

He could vaguely guess that this ghostly shadow was probably the Yin Spirit that Lei Fengxing said.

There are also many kinds of yin spirits, the most common is the ghost after death, but as long as the cultivation does not reach the soul realm, once the body dies, the soul will quickly dissipate between heaven and earth.

However, if the yin qi is extremely heavy, the yin spirit will be nourished, and not only will it not dissipate, but it will grow.

"This Yin Spirit doesn't know if the Dao is naturally generated by Yin Qi or if it is transformed by the soul of someone else after death, but no matter which one it is, it means that this cave is very weird. ”

"What's more, even if Lei Fengxing's spiritual sense is not as strong as mine, after all, it is also the middle stage of the spirit body, he can obviously see the yin spirit through the stone wall, but he didn't say anything for it, but said that the female brother was dazzled?"

"Does he want everyone to feel at ease, but as long as he continues to move forward, he will definitely meet the Yin Spirit, and how long can he be at ease?"

"And this Yin Spirit is really just a low-level creature, and it poses no threat to us?"

Xu You thought as he walked, the feeling of uneasiness in his heart became stronger and stronger, and he also became suspicious of Lei Fengxing, feeling that this person could not be trusted.

At this time, his spiritual sense had already followed the yin spirit deeper than ten meters into the stone wall, but the deeper he went, Xu You's had a cold and piercing feeling, as if the stone wall was sticking out and hiding a piece of 10,000-year-old Xuan Ice, even with his spiritual sense, he couldn't bear it.

Moreover, the speed of the yin spirit was extremely fast, and it disappeared in a negligent manner, while Xu You's spiritual sense was greatly slow to extend in the stone wall, so in desperation, he had to withdraw his spiritual consciousness so as not to be frostbitten by the cold.

At this time, the vigilance of all the children was also raised a lot, and their spiritual sense was scanning back and forth.

Although they didn't look at the ghost shadow that the female brother said, after all, they were all core disciples and well-informed, so they didn't know that there must be something strange in this cave.

However, remembering that Lei Fengxing said that at most there were only some low-level yin spirits or negative spirit beasts, everyone felt a little relieved.

After walking for a while, there was a sudden sound of rushing water in front of me.

Everyone was in high spirits, and the cave was silent, and only their own footsteps could be heard in the corridor, which was a little quiet. Suddenly hearing the flowing water is like returning to nature.

At that moment, a few children quickened their pace and ran in the direction of the flowing water.

Lei Fengxing frowned slightly, but he didn't say anything.

Soon, the space in front of them became more and more open, and as the ground became soft, an open river five or six meters wide appeared in front of everyone.

The river meandered out of a huge cavern, passed in front of everyone, and then sank into another huge cavern.

Although it is still cold, the moisture is blowing in the face, and there is still a moist and fresh taste.

One of the first children to run to the river looked at the river and said with a smile: "This water is really clear, but it is too cold, as if it is ...... inside."

Before he could finish his sentence, suddenly, a black hideous shadow burst out of the river and rushed into his arms.

The boy screamed, poofed, and involuntarily plunged into the river, sinking to the bottom in an instant.

The other disciples were taken aback and hurriedly rushed over, but in the blink of an eye, the river had calmed down, and the child was gone.

Everyone was immediately shocked and angry, this underground river is crystal clear, at most only a few meters deep, that kid just sank, how could it disappear.

"Get out of the way!" Lei Fengxing shouted, raising his hand to send out a blazing fireball, which boomed and smashed into the water where the kid had disappeared.

Everyone hurriedly dodged.

The surface of the water instantly stirred up a huge wave of more than ten meters high, and the fireball went deep into the depths of the water, and then turned into several flames and exploded.

A moment later, the boy floated up from under the river.

His whole body was stiff, and he still maintained a struggling position, but his face was pale, his eyes were hollow, and he had no life.
