After hearing Qing Huyi's description, Lynch couldn't help but ponder: "In this way, the biggest danger of entering the caves and hundreds of caves is to be lost and trapped in it?"

"It's almost the case. Moreover, there will be some mechanism traps in the caves and caves, so you must be careful. Those channels are not unchanged. They can be said to be changing anytime and anywhere. It is possible that the path you have taken will become another path. Of course, there is the most critical point. You should have discovered that the black stones here will hinder the exploration of the spiritual consciousness." Qinghuyi finished speaking.

Lynch raised his eyebrows, and he immediately released his spiritual consciousness and tried to explore. Sure enough, as Qinghuyi said, the black stone here is a very special stone, which will prevent the spiritual consciousness from penetrated and weaken the response of the spiritual consciousness.

Therefore, entering this cave and hundreds of caves is equivalent to becoming a myopic eye, and only seeing what you see in front of you, and the ever-changing channels will make people completely confused about the direction.

"It seems that this is a huge challenge!" Lynch took a deep breath, and he was not sure whether he could escape without the help of his spiritual sense.

"Master, I suggest you not to explore too deeply, just start from several surrounding caves. We have explored these caves, which are a little simpler. The most difficult one is the caves in the middle. So far, no one has come out." Qinghu Yi said.

"Okay, I'll try it first." Lynch chose a hole around him and jumped into it directly.

Swish!

His whole body fell rapidly, and at the same time, the light became darker and darker, and his eyes were pitch black, and he could not see his five fingers.

After about twenty breaths, Lynch finally landed and landed in a narrow passage.

And as his hand moved, a ball of flame burned, and with the light of the flame, he could tell about a range of about ten meters.

But in front of me, there is only one way to continue moving forward.

Lynch groped carefully, took steps, and walked towards the front. Soon, two passages appeared in front of him.

After choosing a channel at will, Lynch continued to walk forward. After about ten breaths, three channels appeared in front of him.

After choosing a channel again, Lynch continued to move forward, but soon, four channels appeared in front of him!

This made Lynch's face feel a little more serious.

If he continues like this, he will just touch the mouse, with no direction at all, and he will not know when he will be in the end!

Moreover, he could feel that after choosing one of the channels, the road behind him was moving and changing little by little, which means that it was impossible to return according to the original path!

You have to find a way!

But, what else can I do now?

"Junior brother, maybe, you can use the law of holy sound." Gu Chen's voice suddenly rang.

"The Law of Holy Sound?" Lynch was stunned.

"Yes, the law of holy sound will produce sound waves. After you make a sound, these sounds will produce echoes in the channel. After you carefully distinguish these echoes, you can distinguish the direction and the end of the channel based on feedback." Gu Chen's words were like enlightenment.

Lynch soon learned what he was going to do.

That's equivalent to that Lynch is now a bat.

When bats fly, they will make a scream. This sound is an ultrasonic wave. After touching an object, they will be reflected back immediately. Therefore, after receiving feedback from ultrasonic waves, bats can identify obstacles.

Similarly, radars on the earth and sonar detection of submarines are also used in the same way.

Lynch was able to figure out these channels by just carefully identifying the feedback from the sound.

As soon as he thought of this, Lynch immediately activates the Holy Sound Law and yells in a low voice: "Explore!"

The sound of the word "加" burst out with a series of sound waves, and these sound waves penetrated into the four channels in front of you.

Soon, after a breath, the first channel on the left immediately echoed, extremely dull, which shows that this channel is very shallow, and the end of the channel is likely to be a dead end, so the sound waves will be fed back so quickly.

After three breaths, there was also a resounding sound from the second and third channels, which shows that these two channels are relatively deep, but the end may also be blocked.

As for the fourth channel, the sound waves fed back are close to and without, like a stone that smashes into the bottomless abyss, with only a little whistling sound.

"It seems that the fourth passage is unobstructed." Lynch pondered.

"Yes, the deeper the channel, the smoother it is, the weaker the sound waves it feedback are, the smaller it is." Gu Chen agreed.

"I really didn't expect that the Holy Sound Law has this effect. In this way, I can choose the fourth channel!" Lynch stepped into the fourth channel directly.

Although this white cave in this cave blocks the spiritual consciousness, it cannot stop the propagation and reflection of sounds. Lynch now uses the law of holy sound, just like carrying a radar with him, which can clearly distinguish the depth of these channels and even the changes in the channels behind him.

"Explore!" Every ten breaths, Lynch would explore the passage again to determine whether the path he was going to go and whether it was smooth.

In this way, Lynch faces the channel selection again and can distinguish the smoothest one.

However, after half an hour, although Lynch walked, he was unobstructed along the way, but he found nothing and did not find a treasure.

"Strange, can it be that all the things in this cave have been found?" Lynch was puzzled.

"No, the space channel among the caves and hundreds of caves is beyond imagination. If you don't have the method of exploring the way, it will be difficult to get out even if you get the treasure." Gu Chen said.

"But now, I don't find anything." Lynch said lost.

"This way, you try it and go to those very shallow passages!" Gu Chen suggested.

"Okay!" This time, Lynch changed his mind and focused on those unblocked dead ends.

Sure enough, after the passage reached the end, a secret room appeared in front of him. This secret room was not big and could accommodate several people, but there was nothing else, only a box, embedded in the wall.

However, this box is very simple, with many totem patterns on it, with extraordinary texture, which also prevents the intrusion of the spiritual consciousness. Moreover, there is no lock on it, as if it is waiting for someone to open it.

"Is it a treasure?" Lynch's eyes lit up.

"Not necessarily, be careful, there will definitely be mechanism traps here." Gu Chen said cautiously.
Chapter completed!
