Cheng Hao had just dodged when the sound of clattering came from the cave next door, and the sound of fingertips slicing across the mountain wall. As if crawling past his ears, he quickly held his breath and concentrated, not daring to leak half of his breath.

Obviously, this time the locusts are bigger.

I don't know how long it took for this sound to stop, and with a long breath, he pushed the stone away and crawled out, and immediately crawled inside, which he had heard just now, and the sound disappeared not far from here.

Finally, after turning a corner, the space suddenly became larger, and a huge hole ran through it, and a thin green mist of light blocked the hole.

Cheng Hao walked over cautiously, and was surprised to find that where the mist came into contact with the mouth of the cave, there were strange formations flickering, and drops of green blood overflowed from it, merging into the slime on the mountain wall.

This green mist turned out to be a formation! It's a kind of formation that has never been seen before!

However, with Cheng Hao, a rookie in the formation who is not even a beginner, it is impossible to break the formation, unless... Brute force try?

Cheng Hao thought about it and dispelled this thought, no one knew what was going on inside, and there were so many demon locusts inside, the ghost knew if he could break through the depth of a few hundred meters above the ground before the resonance attack of countless demon locusts.

Ran Min's voice suddenly sounded in his mind: "Why don't you kid ask, Lao Tzu, do I recognize these formations." ”

Cheng Hao was stunned and said, "You still understand this?" ”

"Hah! Lao Tzu was also the master who could settle the country and govern the people with a pen! ! ! ”

"Yo! Then you came out and showed your hands? ”

“… Lao Tzu didn't say it could be opened... Just know. ”

Cheng Hao couldn't help but be speechless for a while.

Ran Min coughed dryly and said, "Back then, I saw my eldest brother cast a similar formation. ”

Cheng Hao was surprised: "Yo! Who is this big brother, even you, a character with a long mouth and a short mouth, can be willing to be a little brother of others? ”

Ran Min sneered: "Don't be nervous, stinky boy, isn't it itchy skin!" Let me tell you first: my brothers and sisters are suffering in the bloody purgatory, and your kid's leg and life were saved by my eldest brother. You have to step up your cultivation for Lao Tzu and save them as soon as possible, otherwise Lao Tzu will pick your skin! ”

Cheng Hao rolled his eyes and said: "I've heard you talk about it eight hundred times, but you should tell me where the Scarlet Purgatory is first." People give an address for delivery, and you give four words. ”

Ran Min stopped talking for a while, the two were silent for a moment, Cheng Hao knew that Ran Tianwang valued affection, so he spoke first: "Okay, Ran Ye, I am my grandfather, I didn't say no, I signed a contract with you, no, we are not ungrateful... Let's take care of the present, shall we? ”

Ran Min said: "It's good for you kid to remember."

The original version of this formation pattern was handed down by the Wu clan in ancient times. My eldest brother said that this is an innate imprint inherited from the blood of Pangu, and later because of the long period of time, coupled with the Lich Wars that have been fought for so many years, the original version has long been lost.

The one in front of me has obviously been processed and adapted many times in later generations, and it is not even the original fur. ”

Cheng Hao's eyes lit up and said, "Master Ran, does your eldest brother know what kind of innate imprint you have?" ”

Ran Min was stunned for a moment, and then said: "It should be some, I only saw him use it once, and then he used it again." Don't think about any bad ideas, with your talent, let's learn the basic three thousand formations first. ”

Cheng Hao pursed his lips, ignoring his cynicism, and looked at his watch, there was almost an hour.

After thinking about it for a moment, I decided to retreat.

Who knows, as soon as I climbed to the position where I had dug the hole just now, I heard movement in front of me, and another batch... Just hid in the hole he dug earlier, and poked a small hole with his spiritual power.

After a while, I saw a demon locust with a large head and a large head crawling over. Cheng Hao held his breath and concentrated, and suddenly a flash of inspiration flashed, and his heart couldn't stop pounding, do you want to play like this...

Discuss the idea with Ran Min, and Ran Min directly finalizes, do it!

So Cheng Hao closed his eyes and listened carefully to the number of demon locusts behind him, and finally when the last one passed by, he saw the right time and shot a small arc of electricity into the demon locust, paralyzing it temporarily.

Cheng Hao immediately received the blocked cave wall into the storage artifact, and shot another arc of electricity, which stunned the one in front of him, and then he waved his knife and began to clean up the demon locust in front of him.

Three times five divided by two, cut open from the lower abdomen, didn't care about nausea, dug out all the internal organs inside, and after getting into it, Ran Min appeared to stitch up the wound, and applied the green blood evenly to the sutured wound, and then returned to the heart world.

This demon locust is not actually dead, but it is only unconscious, but it may die at any time.

Cheng Hao immediately cast a spell to wake up the one in front of him, and he manipulated the body himself, following closely behind.

The two demon locusts came to the formation of the green fog one after the other, only to see that the demon locust in front of them tapped the mist twice with the slender tentacles in front of their heads, and then entered.

Cheng Hao held back his pounding heart, manipulated his body to come to the green mist, and immediately unleashed a spiritual power to restore the demon locust's sanity, and block its pain, while reining in all his breath and fluctuations.

Sure enough, when the demon locust woke up, it saw that it was already in front of the green mist, so it tapped it twice with its tentacles and climbed in.

After finally coming in, Cheng Hao breathed a sigh of relief and felt the surroundings, there seemed to be no danger, and then he broke out. As for this demon locust, let him die in a coma.

Cheng Hao looked up at this place, and was suddenly taken aback!

Here is a huge cave with a small green lake in the middle!

The demon locust in front of him walked to the lake, planted it at one end, and disappeared without a trace.

Cheng Hao stepped forward and squatted by the lake, and looked at the lake carefully, it was actually the blood of locusts!

Moreover, there are several grooves on the edge of the lake, connected to the magic circle at the entrance of the cave, and it turns out that the slime on the outer wall of the cave is the lake water here.

Ran Min also appeared to take a closer look, but apart from this green pool, there was nothing special.

How did the demon locusts gather here inexplicably, and they were still lining up, jumping down one by one, and there was such a big pool of green blood... How many locusts do you have to kill!

The desert locusts are thousands of miles away, and they come to Huaxia, is it just to pounce here?

Cheng Hao took the shell, and after confessing his guilt, he cut off a leg, hollowed out the contents of it, and put his arm inside.

Then reach into the pool and there is no abnormality. So he ran the spiritual power and thunder and lightning, but there was nothing abnormal, so he was relieved and said: "Heavenly King, this matter is getting more and more weird, and now that the matter has come to this, the matter of obtaining the power of the ghost king, you might as well postpone it first." I'd like to see what this place is all about! ”

Ran Min nodded, and directly turned into smoke and returned to his heart.

Cheng Hao drilled into the shell again, sealed the gap with spiritual power, and controlled the body to jump in.

It's like a rock, constantly sinking, and the surrounding green patch, you can't see anything clearly. Cheng Hao cast a spell and sank quickly until he caught up with the demon locust that jumped in earlier. But it was like hibernation at the moment, motionless.

I continued to sink for a while, and suddenly noticed that there seemed to be a formation fluctuation in front of me!

Cheng Hao immediately looked at the front with all his attention, and after a while, he vaguely saw a golden light shining below, and the one that sank in front was swept by the golden light and immediately turned into a cloud of green mist.

And in the green mist, there was a red line thinner than a hair, which sank downward, and Cheng Hao immediately came out of his body, collected his body, and attached the body barrier to his skin.

Cheng Hao swam to the top of the golden light, stretched out his hand to test it, and the golden light really swept over.

This golden light could clearly detect that something was within its range, and immediately attacked.

It looks like it's supposed to be a formation.

Cheng Hao threw down a piece of clothing, and the golden light instantly smashed the clothes to pieces. I threw a few different things down, and they were all shattered by the blow!

What a golden light!

I frowned and thought about it for a long time, but I didn't think of a way, and even a few pieces were thrown together, but they were all smashed one by one.

Why didn't the golden light shatter that red line?

Cheng Hao couldn't help but touch his hand to the storage belt, took out an object and threw it down.

Suddenly, a scene that made Cheng Hao's eyes widen appeared, only to see that the golden light did not hit the thing. After shaking it twice, it stopped.

It's like a strange move from not knowing whether to smash it or not, to compromising and not smashing it by default.

Cheng Hao was stunned and looked at the maple leaf that had sunk completely, and clapped his hands violently and said, "!" I see, it's the resonant frequency! ”

Ran Min of the heart world wondered: "What... What's that? ”

Cheng Hao said: "Every substance in this world has a fixed vibration frequency, and it will vibrate. But because of the differences in the microscopic particles in matter, the frequency of each substance is different.

If the frequency of the external force acting on the object is the same as the natural frequency of the substance, the amplitude will reach its maximum, which is the resonance! This is the resonant frequency. ”

Ran Min said with a dark face: "Speak human words!" ”

Cheng Hao rolled his eyes and said, "It's that everything has a spirit, and there are signs of life like our human heartbeat." But just as men and women are divided into men and women, old and young, strong and thin, so the signs of life are different among all things.

It's like choosing a marshal from two generals with equal strength but different resourcefulness, and if you choose the most resourceful marshal, the chances of this army winning are greater; Choose those with low resourcefulness, and the army will easily defeat the battle. ”

Ran Min nodded thoughtfully and said, "Then this, do you have a way to get by?" ”

Cheng Hao smiled slightly, took out a step on the maple leaf he had picked earlier, and said, "You also saw it before, there are already maple leaves that will not be broken, that is to say, the natural frequency of the maple leaves themselves is the pass of this formation!" ”

Sticking himself airtight from head to toe, he carefully stretched out one foot. And the golden light only shook twice, and did not hit the maple leaf, Cheng Hao breathed a sigh of relief, his guess was right!

Only then did it slowly sink down a little bit, and the golden light just shook in place.

It's fake to say that you're not nervous, but when you finally sink your body under the golden light, that's what stuffs your heart into your stomach.
