It was as if Xiao Nan silently operated the Yin and Yang Spirit Rhino, and while resisting the magic sound, he slowly walked inside, and Li Qingyi held one of Xiao Nan's hands tightly, and followed behind.

The structure of this cave is very simple, the space in the cave is about four meters high, and many stalactites are slowly dripping water, although the light in the cave is dim, but there is no problem with seeing for Xiao Nan, who is already a half-saint and mid-level.

As the two of them slowly deepened, the magic sound became clearer and clearer, but with the blessing of the Yin and Yang Spiritual Rhino, except for Li Qingyi, who was a little dizzy, he could still keep the Shentai clear. It didn't take long for the two of them to pass a corner, and they could already see the small waterhole in the cave. Suddenly, a black shadow flashed from the edge of the pool, leaping behind a large stalactite, and the cavern magic sound suddenly stopped.

As if Xiao Nan's heart was alarmed, he instantly set up his defense. Li Qingyi was also taken aback, and asked quietly, "Brother Fang Nan, what's going on?"

Yi Xiaonan said: "When this magic sound ended, I saw a black shadow jumping away from the waterhole, did you notice it?"

Li Qingyi said: "I have also seen it, and I thought that my eyes were dazzling, what kind of creature can survive under such a strong magic sound?"

Xiao Nan shook his head and said, "It's true that no creature can survive, but what if this magic sound was originally emitted by this creature?"

Li Qingyi's face became solemn: "Brother Fang Nan, you mean...... Could the shadow be some kind of unknown beast?"

Yi Xiaonan nodded lightly and said, "That's true, let's go up and take a look." ”

If Xiao Nan's guess was correct, this black shadow might be the culprit who created the cave magic sound. The spiritual world is full of spiritual energy, and although most of the ancient beasts have long been discovered, there are often unknown supernatural species in mysterious and remote places. If this strange beast could be used by people, the strange sound that disturbed the minds of other monks alone would be comparable to a first-class magic weapon.

As if Xiaonan and Li Qingyi walked to the shallow pool. The depth of the pool is only about one meter, it is crystal clear, and the water level is estimated to be as high as Yunmengze, which should be connected to the source and Yunmengze.

As if Xiao Nan squatted in the place where the black shadow had been, he searched carefully, and soon found something unusual.

The sand on the edge of the waterhole was very muddy, and it seemed that the black shadow had been hovering here for a long time, and many traces had been left, like the traces of a fish jumping in the mud, but there were small paw prints.

A few inconspicuous traces attracted Yi Xiaonan's attention, he stretched out his finger and touched the trace, and the fingertips were quickly dyed a faint blue.

As if Xiaonan put his finger on the tip of his nose and sniffed it carefully, this strange liquid had a faint fragrance, which made people involuntarily increase their appetite, as if Xiaonan had a ghost who stretched out his tongue and licked his finger slightly. In an instant, a thick vitality spread out from his mouth at a rapid pace, flowing down Xiao Nan's esophagus to the limbs, quickly moisturizing the cells of his body.

This rich vitality not only repaired the damage suffered by Xiao Nan when he was tested on the beach, but also faintly increased his energy greatly.

Perhaps the strange beast secretly saw Yi Xiaonan's move, and the overwhelming magic sound sounded instantly, and this time the magic sound not only had the usual tragedy, but also carried a strong sense of resentment, and seemed to be extremely dissatisfied with Yi Xiaonan's actions.

This sudden close-range magic sound made Li Qingyi snort, squatting down with his head in one hand, and pinching Yi Xiaonan's shoulder with the other hand and not daring to let go.

It was as if Xiao Nan had already been on guard against a sudden attack, his yin and yang spirit was running non-stop, and a trace of pure thunder swam back and forth on him, constantly stimulating his ears and brain, so that this magic sound could never invade his consciousness. At the same time, a trace of thunder light quietly emitted from his fingertips, hitting the source of the magic sound.

The black shadow was extremely sensitive, and it quickly scurried before the pure thunder was activated, and then disappeared behind another stalactite, and the magic sound disappeared again.

As if Xiao Nan snorted lightly, his left hand was held by Li Qingyi, and the five fingers of his right hand quickly opened, and five thunderbolts flew out from the tips of the five fingers of his right hand, along the ground and the wall, and outflanked the large stalactites.

The dark shadow beast let out a piercing scream of rage, dodging the ensuing pure thunder, and swooped down on the two from behind the stalactites. At the same time, several more water arrows quickly condensed in the air, shooting towards Yi Xiaonan.

Li Qingyi was not to be outdone by Yi Xiaonan's side, although her cultivation was worthy of reaching the King Kong realm, but this method of manipulating water aura was originally a method that the Li family was proud of. I saw that she quickly condensed an ice shield in front of the two of them, and stopped the water arrows one by one, and the water arrows attached to the ice shield quickly froze, which made the ice shield stronger.

"Good job!" as if Xiaonan smiled and praised Li Qingyi, he also secretly pinched the law with his right hand, and another pure thunder brewed out in his hand, and he was about to strike out.

And when the black shadow pounced closer and closer, the image of a seven or eight-year-old child jumped into the eyes of the two.

"It's a Terran child!" Li Qingyi shouted loudly, for fear that Xiao Nan would accidentally hurt the child.

As if Xiao Nan was stunned for a moment, the pure thunder in his hand also stopped shooting out, but changed slightly, becoming a thunder net, horizontal in front of the child who pounced.

Seeing the thunder net in front of him, the child twisted his body in the air, trying to avoid the danger that was close at hand, but the five pure thunderbolts that had been struck before, under the control of Yi Xiaonan, also quickly closed over, firmly locking the various escape directions that the child intended to escape.

Although the child was as swift as a ghost, he was very afraid of this pure thunder, and could only be trapped in the thunder net, shouting at the two of them incessantly, making a vicious face, but these vicious faces appeared on the childish face of the child, but it made people feel funny, and did not play the due role of intimidation.

When the child was trapped in the thunder net and couldn't move, it seemed that Xiaonan and Li Qingyi had time to take a closer look. Originally, when the two of them saw the face of the child flying towards them, they thought it was a Terran child, but now when they take a closer look, it is not like that.

The little creature had blue hair and blue eyes, and its upper body was Terran, but its lower body was snake-like and scaly, and its tail had fins like fish tails.

There was a thin layer of white membrane still left at the end of his tail, hanging softly on the ground, and there was a tearing wound at the junction between the white membrane and its body, and it stared at the pure thunder that was close at hand in the thunder net and turned back and forth anxiously, and roared at Yi Xiaonan and Li Qingyi.
