The Strongest Doctor

After listening to qinghuyi's description, Lynch could not help but ponder: "in this way, the greatest danger of entering the caves is to lose direction and be trapped in them?"

"It's almost like this. In addition, there will be some traps in the caves. You must be careful. Those passageways are not the same. They can be said to be changing anytime and anywhere. It's possible that one road you've taken will become another. Of course, the most important thing is that you should find that the black stones here will hinder the exploration of divine consciousness 。” Green fox righteousness finish.

As soon as Lynch raised his eyebrows, he immediately released his divine consciousness and tried to explore. Sure enough, as qinghuyi said, the black stone here is a kind of special stone, which will block the penetration of divine consciousness and weaken its response.

Therefore, entering the caves is tantamount to becoming a nearsighted person, who can only see what he sees in front of his eyes. The ever-changing passage will make people completely confused about the direction.

"It looks like a big challenge here!" Lynch took a deep breath, and he was not sure whether he could withdraw from the whole body when his divine consciousness had lost its function.

"Master, I suggest you don't explore too deeply, just start from the surrounding caves. We have explored all these caves, which is a little simpler. The most difficult one is the middle caves. So far, no one has come out." Green fox justice.

"Yes, I'll try first." Lynch chose a hole in the ground around him and jumped directly into it.

Shua!

His whole body fell rapidly, and at the same time, the light became more and more dim. His eyes were dark, and he could not see his fingers.

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

With the movement of his hand, a fire started to burn. Depending on the light of the fire, he could distinguish the range of about 10 meters.

Just in front of you, there's only one way to move on.

Lynch groped carefully, stepped forward, and soon there were two passages in front of him.

He chose a passage at will. Lynch continued to walk forward. After about ten breaths, there were three passages in front of him.

He chose another channel and Lynch went on, but soon there were four more channels in front of him!

This made Lynch's face a little dignified.

If he goes on like this, he will be blind cat touching mouse. He has no direction at all. He doesn't know when it will be!

Moreover, he can feel that after choosing one of the channels, the road behind him is moving and changing a little bit, that is to say, it is impossible to return according to the original road!

We have to find a way!

But what else can we do now?

"Younger martial brother, maybe you can use the Shengyin rule." The sound of ancient dust suddenly sounded.

"The law of the voice?" Lynch was stunned for a moment.

"Yes, there will be sound waves in the sound law. After you make a sound, these sounds will produce echoes in the channel. After you carefully identify these echoes, you can identify the direction ahead and the end of the channel according to the feedback." Ancient dust's words, like the top.

Lynch soon learned what he was going to do.

It's like Lynch is a bat now.

When bats fly, they will make a sound, which is a kind of ultrasonic wave. When they touch an object, they will immediately reflect it back. Therefore, after receiving the feedback of the ultrasonic wave, bats can identify obstacles.

Similarly, radar on the earth and sonar detection of submarines also use the same method.

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

As soon as he thought about this, Lynch immediately ran the law of holy sound and whispered, "detective!"

The sound of the word "probe" burst out a series of sound waves, which penetrated into the four channels in front of us.

Soon, after a breath, the first channel on the left immediately sent a burst of echo, extremely dull, which shows that this channel is very shallow, and the end of the channel is likely to be a dead end. That's why the sound wave feedback comes back so quickly.

After three breaths, the second channel and the third channel also received a burst of echo, which indicates that the two channels are deep, but the end may also be blocked.

As for the fourth channel, the feedback sound wave, close to nothing, is like a stone, falling into the abyss, only a little whistling sound.

"So the fourth passage is unobstructed." Lynch thought.

"Yes, the deeper and more unobstructed the channel is, the weaker and smaller the sound wave is." Gu Chen agrees.

"I didn't expect that the law of Sheng Yin would still have this effect, so that I could choose the fourth channel!" Lynch went straight into the fourth passage.

Although the white cave in this grotto blocks the divine consciousness, it cannot block the transmission and reflection of sound. Lynch now uses the law of holy sound, which is like carrying a radar with him. He can clearly distinguish the depth of these channels, even the changes of the channels behind him."Detective!" Every ten breaths, Lynch will explore the passage again to determine whether the road he wants to take is unobstructed.

In this way, Lynch will be able to identify the most unobstructed one when facing channel selection again.

However, after half an hour's walking, Lynch had no obstacles along the way, but he got nothing and didn't find a treasure.

"It's strange that all the things in the caves have been found." Lynch wondered.

"No, the space passageway in the caves is more complicated than you think. If you don't have such a way to explore the way and just rely on yourself, it will be difficult to get out even if you get the treasure." Ancient dust road.

"Just now, I haven't found anything." Lynch lost.

"Well, you try, go to those shallow passages!" Gu Chen proposed.

"Yes This time, Lynch changed his way of thinking and chose the dead road that was not smooth.

Sure enough, at the end of the passage, a secret room appeared in front of him. The secret room was not big enough to hold several people, but there was nothing else. There was only a box embedded in the wall.

However, this box is very simple. There are many totem patterns on it. The texture is extraordinary. It also blocks the penetration of divine 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 brightened.

"Not necessarily. Be careful. There must be traps in it." Gu Chen said cautiously.

Lynch nodded. The caves are very mysterious. Who knows what they are hiding?
