In the world, in the red desert.

Zebra releases ultrasonic noise, which makes the desert sharks disperse like birds and beasts.

Then there was a violent vibration all around.

Riding on the camel, feeling very bumpy, zebra jumped down.

When Leiyin pulls Natalie to jump, she finds that Natalie is gone.

Not only that, but also the two camels fell into the desert and were quickly rolled down.

A flash of thunder sound disappeared in the same place.

Zebra's hearing was superb. He could tell the location of quicksand and solid sand at once, and his feet soon fell into place.

At this time, many strange looking monsters appeared in the sand and surrounded them.

"I want to see where the girl is, but it takes concentration to do that, and you're going to have these guys," zebra said

Leiyin understands that zebra wants to locate the lost Natalie by using her unique echo technique.

This guy is very loyal.

Lei Yin said with a smile: "I don't object to it, but I can do both."

Zebra looked at him. "What do you mean, kid?"

"Let's deal with these things in front of us first."

Lei Yin said, his right hand quickly sealed.

Zebra first heard a strong smell of gunpowder, and then the temperature around her suddenly rose.

[the gray array blocking the sight immediately turns the burning fire into explosion! 】

"Huodun · huijishao!"

Lei Yin drank softly, and at first he spat out a thick gray smoke. The monsters seemed to be aware of the danger and stopped one after another.

Then there was a fire all around, and the fire was burning all around.

Soon, the surrounding ghosts and spirits were burned out.

Almost at the same time of thunder, zebra also launched his own ability.

Centered around his body, sound waves spread like radar.

Echo map!

It's also called echolocation, or biological sonar. It's a kind of ability to judge the surrounding situation according to its echo after it emits sound or ultrasonic wave. With this move, zebra can master the size and distance of objects tens of kilometers away in detail. Of course, like the fish school detection system, zebra can also use this move underground or underwater.

Using this move requires a high degree of attention. Assuming zebra expands the positioning range to tens of kilometers, he will not be able to use other moves.

That's why he let Lei Yin destroy the monsters in front of him.

When zebra unfolded the echo map, he was shocked.

He didn't find Natalie.

He has expanded the map to the maximum extent.

Suddenly, zebra spat out blood.

Because he was going to extend the map, but he had already exceeded his limit, and his throat couldn't bear it, so he vomited blood.

Lei Yin said: "Lao Bu, I appreciate your kindness, but take back your ability and save energy. I already know where Natalie is. She is safe now."

"Well?" It's really hard for Zebra to expand the [echo map] for tens of kilometers, and it will consume a lot of physical strength to drive it all the time. After listening to Lei Yin's words, he took back his ability, "what do you mean by this?"

Leiyin grabbed zebra's shoulder: "come with me."

As soon as the words fell, they rose into the air.

Zebra couldn't help but wonder: "this guy has the ability to fly?"

Soon they were in front of a huge building.

A huge pyramid.

Food pyramid!

"This, this is --" when he saw it, zebra was a little stunned.

Even Lei Yin didn't expect that the pyramid was extremely huge. Looking up, it was at least 500 meters high.

But this is just the tip of the pyramid.

Zebra has turned off the echo map. Why does Lei Yin know?

Of course, it's the thunder that makes people feel powerful.

One of the explanations of the other world is "the power of hearing".

In the pirate king, Teng Hu, a navy general, can feel the location of the meteorite in outer space with a smile and pull it down with the ability of its gravity fruit, while Charlotte katakuli, who is famous for seeing and hearing, can even predict the future.

Lei Yin still remembers that zebra's maximum listening distance seems to be 70 kilometers.

From this point of view, Tenghu and katakuli seem to have stronger perception than zebra.

And the perception of Leiyin is far better than Tenghu and katakuli.

That's why he felt the position of the pyramid and told zebra that Natalie was safe.If we have to say how far the perception of thunder sound is, it will be an astonishing astronomical number.

When the thunder sound is spread out, it can easily reach thousands or even tens of thousands of kilometers.

If the distance is further extended, he can even feel some unknown underground creatures on the planet, and even touch the planet.

The reason why Leiyin is so calm after Natalie lost is that he not only perceives her position, but also adds a layer of protection to her.

It's totally impossible for ordinary people or even food hunters with considerable strength to do this, but it's just a drop in the bucket for Leiyin.

"It seems that we have arrived, boy. You don't let me use my ability. Don't blame me for that girl's death." Zebra urn sound urn airway.

Lei Yin said with a smile: "I appreciate your kindness. If Natalie is really lost, I will be more anxious than you, but she is really OK now."

Zebra said: "look at the pyramid in front of you. The height of the pyramid is at least 500 meters. It's just the tip of the iceberg in the whole pyramid. Your woman fell into quicksand and fell down dozens of kilometers at least."

"Don't worry about it."

Lei Yin said, back more than 50 steps, and then moved more than 20 steps to the right.

"That's about it."

Thunder murmured, and zebra was completely surprised by what happened.

Lei Yin's right index finger and middle finger, two fingers into a sword, the body of the grand energy is surging.

"The silver knife is flashing!"

The two fingers stroke lightly on the ground like that.

There was a crack in the ground, followed by an unprecedented sense of vibration.

The shock is more than a thousand times stronger than the quicksand collapse just now.

"This, this is?" Zebra's eyes were as wide as brass bells.

The cracks in the sand extend for thousands of meters toward the other side of the pyramid, and there is a huge abyss and gully.
