Gradually, the sound of stones and wreckage falling into the water disappeared, and the surroundings became quiet, in the darkness without any light, Lu Tao could not do anything except wait for the predecessor of the wind kite in place.

After waiting like this for ten minutes, Lu Tao had to start thinking about other methods.

If Lu Tao's sense of space is not confused, this should be the underground at the bottom of the lake, so as long as the underground river can be found, and there is no need to consider the size and length of the hypoxic underground river, there is hope to find a way out, then, the only question is, where is the underground river?

Lu Tao submerged his palm under the knee-high water, feeling the direction of the water flow, sure enough, the water here is flowing, Lu Tao confirmed the direction of the water flow, and thought about the direction of the upstream direction.

The bottom of the lake is much lower than the ground, and there is basically no lower place around, so if you want to get out, you have to go upstream.

Lu Tao adjusted this direction as he walked upstream, and only the sound of water from Lu Tao's advance was left in the darkness, which eased the uneasiness in Lu Tao's heart a little.

It's just that soon Lu Tao encountered a problem, he was blocked by a wall, and layers of water flowed down the wall, but there was no place for Lu Tao to climb.

Moving forward along the entrance of the cave, Lu Tao found a faint light shining from the position at the end of the passage, and couldn't help but feel happy in his heart, and accelerated the pace of progress.

Rushing out from the end, Lu Tao was stunned by the scene in front of him.

It's a small underground lake, and of course, the point is not the point, it's the pale blue spots of light that float above the lake, which illuminate the surface of the lake, making it look like a large sapphire set in the ground.

These points of light floated quietly in mid-air and did not move, Lu Tao stepped forward, but he couldn't see what kind of structure the blue points of light were, probably not an insect, of course, it couldn't be a plant, Lu Tao closed his eyes and used inward vision to perceive them, but found that they didn't even have aura on their bodies, and there was nothing under the inner vision.

After thinking about it, Lu Tao stretched out his hand to try to touch these blue points of light, but stopped at a distance of only one centimeter.

Lu Tao hesitated a little, what if these blue points of light were poisonous? Or maybe Lu Tao was wrong, they were a terrible insect? Finally, Lu Tao gritted his teeth and touched the light blue point of light in front of him with his fingers.

Retracting his hand, Lu Tao glanced at his fingers, neither being punctured nor showing signs of poisoning on his body, but a warm feeling, but the light blue light spot on the other side changed, it trembled a little, and then, this tremor spread, passing to other light points around, Lu Tao retreated to the entrance of the underground lake, and released the ice mirror technique to guard against possible dangers.

However, the change did not come to Lu Tao, when the initial tremor was transmitted to each light blue point of light, they suddenly stopped, then converged inward, and finally, turned into a large light blue ball of light.

The ball of light stopped in the center of the lake for a while, and then slowly floated towards Lu Tao, who resisted the idea of turning around and running, and stared at the ball of light.

"Hello. ”

A somewhat muffled voice sounded in Lu Tao's mind, needless to say, the source of the sound was only the light blue ball of light in front of him, Lu Tao was vigilant about the movement of the ball of light, and asked, "Who are you?"

"I'm a spirit beast sealed here, this is a part of my primordial god, can you save me?"

This voice gave Lu Tao the feeling that he was like another wooden man, who could only answer questions mechanically or speak in a predetermined way, lacking emotion. Lu Tao thought for a moment and continued to ask: "I'm just a little monk in the Qi refining period, I don't know if I can save you out, and if I rescue you, can you take me out? I'm trapped here." ”

"Of course, just do what I say, and you can save me, and the realm is not a problem. ”

"Okay, then I'll help you, what do you need me to do?" Lu Tao agreed after thinking about it for a while, in addition, Lu Tao really didn't want to base his hope of escaping on the fact that he could just find an underground river that would lead to the ground and would not suffocate people to death and allow one person to pass through, and since this voice claimed to be a spirit beast, Lu Tao was also a lot more relieved, in fact, it didn't matter if the demon beast was there, the Mo Lan at home was still a demon beast.

"Please follow me. ”

The voice continued to sound in Lu Tao's mind, so Lu Tao followed behind the ball of light and walked back along the previous passage.

Walking to the previous entrance, Lu Tao found that there was a huge mural painted on the wall that blocked the way before, because the light blue light ball can illuminate a limited range, Lu Tao can only see part of the mural, the description above, it seems to be the scene of the monk and the huge monster fighting, all kinds of strange magic weapons are thrown at the middle of the monster, the monster has a huge body like dead wood, but there are three snake heads, each head releases attacks of different attributes, flame, poison and ice.

There was more than one battlefield on the battlefield, and walking forward, Lu Tao saw other completely different murals, all of which were magnificent battles between monks and strange-looking giant monsters, and gradually, there were many strange human beings on the ground, either tall enough to be ten meters tall, or a pair of wings stretched out from their backs, and they fought side by side with the monks on the ground, fighting against those hideous monsters. Further up, it is not clear that the range that the light blue light ball can illuminate is really limited, Lu Tao vaguely saw a large shadow between red and black, in contrast, there is a feeling of covering the sky and the sun.

"This way. Some muffled voices rang out again, pulling Lu Tao out of the strange world painted by colored paint.

Following the ball of light floating up and down, Lu Tao soon saw a new hole, Lu Tao looked back at this piece of space that he didn't know how much space there was, and wondered if there would be dozens or hundreds of such holes and passages.

This time the entrance to the cave was much narrower than before, and Lu Tao could only bend down as slowly as possible, taking care not to hit the hard stones above his head.

"Since this is an array, can you tell me what the big array here does, and why is there such a large space down there?"

As Lu Tao walked, he asked the question he had always wanted to ask.

"This was originally a mine cave for the spirit stone vein, and when I was caught and sent here, the aura of the ore vein below had not completely disappeared. The low voice of the ball of light that did not fluctuate sounded in Lu Tao's mind: "As for the effect of the big array, I don't know. ”

Lu Tao looked left and right, it turned out that this was the mine cave of the spirit stone vein, and Lu Tao took out the three golden balls from his pocket: "Do you know what this is?"

After asking this question, Lu Tao felt a strange feeling coming from the light blue ball of light, and then, the unique voice of the ball of light sounded: "I don't know, my divine sense can't penetrate their surface, one of them has my breath left on it, the other one has some kind of demon beast's breath left on it, and the last one has no breath at all." ”

Lu Tao was a little disappointed, the golden ball with some kind of demon beast breath left should be the one he got when he inadvertently rescued Mo Lan that time, the one without breath was taken back by Hei, Lu Tao shook his head, put away the three golden balls, and took out the token that said "Dragon Ruins", sure enough, the light ball still didn't know the origin of the token, Lu Tao regretted it a little, if he brought that strange bone, maybe he could try again.

At this moment, Lu Tao suddenly didn't know what to ask, and then followed behind the ball of light, thinking about what other questions he had: "By the way, do you know the Spirit Beast Sect?"

The light blue ball of light paused very rarely: "Spirit Beast Sect...... Is the Spirit Beast Sect still there? I thought it had been destroyed. ”

Lu Tao nodded: "It's really destroyed, the original place of the Spirit Beast Sect is now gone, and most of the buildings have also been destroyed, do you know?"
