- Half of this passage came from the wings of the insect, and the other half was said by Wu Lingzi, who walked back slowly, but during this time, there was no change in the tone of his voice, and the continuation was extremely natural, if it wasn't for Huang Chang's own eyes, he would definitely think that Wu Lingzi had been talking by his side.

Huang Chang put the insect in his hand and leaned in front of him to observe it carefully, but unexpectedly, the insect suddenly fluttered its wings on its face, and its mouthparts opened, biting Yao Xiu's face like pincers - of course it failed to bite, Yao Xiu's body protection kung fu plus the corpse demon template bonus, its body was already as hard as iron and stone, and ordinary swords could not hurt it, let alone the insect mouthparts - of course, this is also because the echo insect is not a combat type after all, if it is the legendary gold devouring ant that can bite and devour anything, Huang Chang would not dare to be so careless.

"Hey, be careful, this thing eats meat...... My favorite is carrion, and I've always fed them with my own body so that I can control it. Yao Daoyou, I'm afraid you can't stand this. However, the amount of food alone is not large, as long as you bring some meat with you, you can raise it for a long time. ”

Wu Lingzi casually dug up a large piece of rotten meat from his body and handed it over, if it was a normal person, he would have run aside and vomited, but the corpse demon would not feel disgusted by this, Yao Xiu took it casually, as naturally as if he had taken a bag of dog food.

...... According to Wu Lingzi's instructions, Huang Chang used the corpse demon breath to perform some simple manipulation of the echoing worm, so that it could make sounds as needed, as well as sense the surrounding areas where there were companions, and also learned to identify some of the signals it sent, after this powerful and murderous "Yao Daoyou" finally accepted Wu Lingzi's suggestion.

Yao Xiu took an echo worm into the underground tomb and hid. Wu Lingzi, on the other hand, made a little arrangement on the outside, making this place more flawless, and at the same time leaving an echo insect on the surface as a sentinel...... When everything was arranged and the sky was already shining, Wu Lingzi hurriedly found a broken coffin for himself and got in.

............

Outside the mountain beams, Huang Chang slowly opened his eyes, but a smile appeared at the corner of his mouth:

"Echo bugs? Pretty interesting little thing......"

This world is so big, and sure enough, there are countless strange things, and Wu Lingzi, a waste corpse demon who looks obscene and useless, actually hides such a strange thing - in the world of cultivating immortals, you really can't underestimate anyone.

With the help of the Echo Worm, anything that happened in the graveyard, even the words of everyone who passed by, could be eavesdropped—no wonder the corpse demon was almost completely ineffective, but it was always able to evade threats, and it turned out that it had this skill.

It is estimated that Wu Lingzi will use this kind of echo insect to lay a detection net around every place he goes, so for many years, as long as there are rumors that may threaten it in a certain place, it can be discovered in time, and the danger can be detected in time, so it will naturally always be able to avoid evil and successfully escape.

The mutual sensing range of the acoustic insects themselves is still limited, but it is only a few miles, and it cannot be sensed no matter how far away. But the sensing distance between Huang Chang and Yao Xiu is far enough. The information that Yao Xiu can get, he can know like Huang Chang, so that even if he stays at home in Baonan City, he can know the situation in that area at any time.

- This ability is only used to monitor a cemetery, it seems to be a bit wasteful, I can't see that Wu Lingzi is a good hand at intelligence, Huang Chang has not paid much attention to it before, but he will pay attention to it in the future.

However, Huang Chang didn't want to alarm it yet, so let's do it for the time being. Anyway, I don't have too many targets to focus on here, so I'll get acquainted with it in the future, and then think about solicitation.

After patting the dust on his body, Huang Chang stood up and walked towards the side of the tomb mountain—he had to try it himself just to be on the safe side.

Unfolded his body, he soon ran to the area around the cemetery, at this time the sky was already bright, most of the civilians of Baonan City were buried here after their deaths, and there were often people near here during the day: those who went to the grave to worship, and those who went out to bury them...... Although it is not lively, it is not uncommon.

Huang Chang pretended to be a Taoist priest, pretending to recite the scriptures of the super-dead soul, and then "inadvertently" walked to Yao Xiu's tomb, and sure enough, Yao Xiu got a reminder from the echo worm below. Including Huang Chang's footsteps and the minor tune humming in his mouth...... were all transmitted underground by the echo insects one by one, so that Yao Xiu below could "hear" all the movements on the ground.

Out of some bad taste, he wandered around the graveyard again. Looking for Wu Lingzi's hiding place, but he didn't find it - this guy was really able to do it without leaking any undead breath when he pretended to be a dead body. Huang Chang always felt that Yao Xiu couldn't detect Wu Lingzi's existence because his divine sense sensing ability was too poor. But now that he has changed himself, with his powerful divine sense similar to Fa Yuan, he can't even scan it.

Of course, Huang Chang actually roughly knew where Wu Lingzi was hiding, and if he really wanted to look for it, he could still find his coffin. But Huang Chang didn't want to scare it. This guy is very timid, and the slightest wind and grass will smear the soles of his feet with oil.

It's okay for a wandering Daoist to inadvertently pass by the coffin, but if that Daoist still puts on a search posture, even if there is no gain, Wu Lingzi probably won't dare to stay here any longer.

After testing the "Echo Bug Alarm System" and getting satisfactory results, Huang Chang left for home and continued to practice Huang Xu and Huang Zhao's "trumpets".

On the side of the tomb mountain, after occasionally welcoming a few tourists, most of the time, it still maintains a lonely and lonely scene. Especially after dark, there was silence, and apart from the occasional sound of a few wild beasts that came to feed, there was no movement of any other living creatures.

- until some human beings with special needs appear here.

............

"Click, click, click, click......"

Heavy footsteps broke the silence, and several pairs of iron-soled leather boots worn by warriors stomped heavily into the mud, perhaps crushing a few bones, making a tooth-aching clicking sound that became more and more permeable in the darkness.

"Sixth brother, take a lighter step. I know you're scared, but you don't have to rely on this courage, right?"

"Fuck your fart! Old Eleven, you're scared and want to pee your pants, but don't rely on others!"

"Hehe, if you're not afraid, sixth brother, why did you beg Fifteen Lang to give you another exorcism talisman yesterday?"

"You know what a fart! Lao Tzu's original one is almost out of power, of course he has to change it to a new one...... Otherwise, wouldn't it be bad if you needed it and it didn't work!"
