At this time, having just completely gotten rid of the previous crisis, the moon worship has also woken up, so everyone's hearts are extremely relaxed, so no one is mentally prepared for this, in this extremely empty underground world, they will actually hear a strange sound of this 'dong dong' coldly!

The sound came very suddenly, and it sounded very strange, echoing in this empty place, almost like a knock on the door in a deep alley, but this place is not even a door, not even a hair, so where did this sound come from?

Wu Yi froze suddenly when he reached out to take out food from his backpack, hurriedly grabbed the wolf's eye flashlight on the ground, turned his head to look left and right, but he gasped in his heart, what the hell is this thing messing with? I don't do anything bad for people, I'm not afraid of ghosts knocking on the door in the middle of the night, and I haven't done anything bad for a few of myself, why did I catch up with this cold knock again? And there's no ghost here...... No, didn't that fat guy bury a corpse that has been dead for an unknown amount of time just now, could it be that her ghost thinks that the fat man is too picky and gives too few funeral goods, so she comes out to scare herself?

These thoughts flashed through his mind almost in the blink of an eye, and Wu Yi shouted at the fat man,

"Fatty, I think nine times out of ten it's your life-saver who is joking with us! You were always staring at other people's breasts just now, this time it's okay, people won't leave because of you! ”

The fat man was choked by Wu Yi's words, and scolded,

"You grandson don't talk nonsense, fat man, I'm not interested in dead people, and you listen carefully to this voice, it comes from above, it seems that someone is lying on its stomach, quickly hit a flare, there must be a situation above!"

"Above?"

Wu Yi listened carefully, the sound really came from the top of the cave above, and he suddenly broke out in a cold sweat, and said that he only paid attention to the situation around him just now, and ignored the top, could it be that someone quietly touched the top of the cave from above? Hurriedly pulled out the flare gun from his backpack and fired a shot at it.

After the flare was illuminated, Wu Yi and the fat man both looked up at the same time, and couldn't help but look at each other at a glance, on the top of the cave above, except for the stones of different sizes hanging upside down, there was no figure, but the knocking sound of 'knock knock, knock knock' still kept ringing, and this time because they knew that the sound was coming from above, so they could hear it more clearly, it would have a short pause every few times, and then it would continue to ring, it was really like a person tapping regularly on it!

The blind man was also surprised enough, but he was an expert at listening to sounds, and at this time the blind man immediately heard that something was wrong, and said,

"No, Wu Ye, this sound doesn't seem to be sounding on our floor, even if someone really knocks on the stone, it is also knocked on the top of this cave, you listen carefully, its echo is not particularly heavy, it is obviously separated from us from the top of this cave!"

To the blind man, Wu Yi and the fat man listened carefully, and when they heard it, they suddenly calmed down a lot, even if there was really any monster, it was on the upper floor, even if he knocked on it weirdly, through the thick roof of the hole, he couldn't get down.

It's just that what is there on the upper floor? Could it be that the group of tomb robbers I met before were sending a distress signal to a few of them? Or did you really come across the legendary ghost knocking on the door?

Wu Yi looked at his watch, it was one or two o'clock in the middle of the night, it was indeed the best time for a supernatural event to occur!

The fat man was silent for a while, but suddenly he let out an 'oh' and clapped his hands,

"I thought of it! I know what this is! ”

Wu Yi glanced at the fat man, but seeing that the fat man's face was a little strange, it was obvious that what he was going to say later should not be a good thing, so he was ready to listen to his nonsense.

The fat man approached Wu Yi and the three of them, pointed to the voice from above, and said,

"Have you forgotten the legends here, the ones that the girl and her uncle told us when we came!"

Wu Yi pondered for a moment, frowned and said to the fat man,

"What kind of legend is that, it's some supernatural event, which one are you referring to?"

Although Wu Yi still remembered those supernatural events in his heart, he didn't want to recall them in his mind at all, and Wu Yiyi really didn't remember that there was a knock on the door in those supernatural events for a while.

The fat man shook his head with hatred of iron and steel, and said,

"You, you do have some skills now, but your ability to collect intelligence information is still too poor, every special thing you hear on the way to the fight may be of great help to our tomb robbers, you must always keep it in mind, how can you forget that?"

The knocking sound above was still continuing, but it seemed that there was no direct danger except for some cautionary panic, so Wu Yi and the others also calmed down at this time after the initial panic. After all, this weird situation is far from fighting with zongzi with real guns, and it is far from the point where a few people panic, so at this time, the fat man is still as fond of talking as usual.

Wu Yi glanced at the fat man and urged,

"Which one are you referring to, you hurry up and say, don't sell anything at this time!"

Fat Man Dao,

"Did you really forget? That's it, didn't the girl's uncle say that when the villagers slept until midnight, they could always hear a 'knock knock' from under the floor of their house, as if someone was knocking on the ground to get out.

The situation we encountered is actually very different from what he said, but the position of the sound has changed, they are under the floor, and we are on the ceiling, but the reason should be the same! ”

When the blind man heard this, he immediately nodded and said,

"Well, what the fat man said makes sense, if it's really that kind of sound, then we don't need to worry, after all, after the villagers heard that kind of sound, they still lived in the village for a long time, which shows that the sound itself is not dangerous."

As soon as Wu saw that the fat man didn't seem to finish speaking, he pulled the blind man and motioned for the fat man to continue.

Fat Man Dao,

"In fact, this kind of sound under the floor and from the ceiling, fat man, I have heard similar before coming here, many residents in the building community react, in the middle of the night can hear footsteps upstairs, the sound of glass balls rolling, and the sound of pulling the table, I think these problems they react to, and we and the villagers encounter this situation, it should be the same, nothing worth smacking lips."
