Panicked and buried the sleeping bag, the man refilled the earth, loosened it gently, put the surrounding turf back on, and stepped on it as if he were stepping on an enemy with anger.

After cleaning up the traces on the ground, the man carried the tools back to the fourth residential building.

He walked fast, but Ye Feifei still saw his black rain boots...... It was covered with fresh mud.

He forgot to clean up the mud!

Ye Feifei didn't rush to follow, the flaw in front of him was probably the bait thrown by the other party...... If you really do something bad, you will definitely be thoughtful, and the flaws in front of you are not like what a criminal should do.

As it turned out, the sober mind and cautious mind were right, and the middle-aged man returned to the lawn with his hoe in his hand after ten minutes.

No one!

Really sure that no one was in secret, the middle-aged man took out two plastic paper pockets from his pocket and wrapped the two rain boots respectively...... Immediately afterwards, you took out a towel and wiped the soil on the ground vigorously, and then walked into the residential building with satisfaction.

The middle-aged man walked extremely fast, but Ye Feifei found that he was not an ordinary person, and there were no footprints everywhere he walked...... The two plastic paper pockets seemed to be just to hold the mud, and they didn't affect his strength.

Seeing the other party close the door casually, Ye Feifei hurriedly followed.

The doors of the residential buildings are open, but you need to turn the handle every time you enter and exit...... The sound was neither high nor low, and cultivators could hear it.

Fortunately, the middle-aged man did not close the door tightly after entering, which gave Ye Feifei an opportunity...... He leaned lightly against the door, listening to the grinding sound inside.

The sound of the cultivator's footsteps was hard to hear, but the sound of the clothes rubbing against his body would not go away...... Ye Feifei's hearing was really terrifying, listening to the sound of the other party's clothes rubbing, and judging the other party's position from this.

Silent boots can hide these sounds, which is also a secret that Ye Feifei has never been discovered.

With a subtle "click", Ye Feifei speculated that the other party might live on the first floor, and the sound was the sound of the key being unlocked.

With the sound of the door closing gently, Ye Feifei pushed open the door and slipped in, gently closing the door, but not closing it tightly.

The residential building was pitch black, and the walkway was only big enough for two people to walk side by side...... Ye Feifei, who was leaning against the wall, reached out to touch the texture on it and touched the black ...... in his hand It was a black stain from burning, which was particularly difficult to remove, and it was not pleasant to get a little bit in your hands.

Ye Feifei really couldn't figure it out, ten years have passed, why are the walls still black? Can't you just repaint it?

Slowly groping forward, Ye Feifei found the staircase, but he didn't find an elevator or anything like that, it seems that there is no elevator in this residential building!

But think about it, how can an old building install an elevator for you? It is estimated that there are no elevators in the old buildings in the old neighborhood, and all of them need to rely on people.

There is only one staircase, one down, the other up, and there are only two houses on the left and right of the first small platform.

Just a middle-aged man, living in one of the households!

With the help of darkness, Ye Feifei did not appear in the cat's eyes of the two portals, avoiding the prying eyes of the person hiding behind the doors, and quickly stepped on the stairs going down.

After waiting quietly for a while, Ye Feifei heard the "click" sound of flip-flops coming from the room at door 101, and speculated that it should be the middle-aged man's residence.

Why does it sound like flip-flops? It must have been a change of shoes, and the only one who had just changed his shoes was the middle-aged man in rain boots.

If not convincing, then the sound of running water in the room is the best proof, he is washing the mud from his rain boots.

I came here today to look for the bright W newspaper den, and Ye Feifei didn't want to make any extraneous branches, so he just wrote down the house number, and planned to wait for dawn to ask the driver about these situations.

The downward staircase slowly became open as Ye Extraordinary walked, passing through two small platforms, and finally reaching the bottom.

Underneath the fourth residential building is a basement where cars are parked...... To be precise, it's an underground parking lot.

The lights in the parking lot were a faint green, the walls were pitch black, and even the light was a little shaky, and the walls that were in the light were showing signs of cracking and peeling.

When you come to an unfamiliar environment, the first thing you need to make sure is whether there are people around, and the second thing is to look for the intersection.

To put it simply, the parking lot is very quiet, there are no people, there are no stairs, only an exit passage of about 30 meters.

Seeing this scene, Ye Feifei had a feeling of being deceived, what about room 404 underground?

Sanjiu's expression at that time didn't seem to be deceitful, and he was naturally a little suspicious of this place after experiencing the Infinite Corridor...... Is there some mysterious little world after all?

Stepping into the small world, all you need is to find the conditions to enter, and then the trigger mechanism can let him in.

After walking around the underground parking lot, Ye Feifei didn't gain anything, but found it in a blue jeep...... Saw a puddle of liquid stains on the ground that were not very obvious.

The jeep's glass has some pinhole-sized black dots, and the stains on the ground are dark red, and it hasn't been long since it dried.

Carefully turning on the flashlight, Ye Feifei shone the light on the ground, lay down to observe, and then got up to observe the window glass.

The stains on the ground were a mixture of blood stains and diesel, and the fishy smell that had not yet dissipated made Ye Feifei smell it...... The black spots on the windows weren't bloodstains, but they smelled of diesel.

The doors of the jeep were locked, and there was a peace blessing hanging in the car, and there was a stall of red in the driver's seat that had not completely faded.

Further observation shows that the black dots on the glass are outside the car window, not inside the car window, which gives Ye Feifei infinite space for reverie.

Searching on the ground with a flashlight, Ye Feifei soon found a drop of liquid on the ground not far from the vehicle...... It was a dry, oily stain with diesel fuel and a fishy smell!

The conditions were met, and Ye Feifei deduced that there had been a murder here not long ago, and the murderer might be the owner of the 101 house number (that is, the cautious middle-aged man).

The owner of the jeep took the middle-aged man to the basement, and the two seemed to have an argument, so the middle-aged man was moved to kill, and the owner of the jeep fell into the driver's seat......

The panicked middle-aged man used the reserve diesel fuel in the car to cover up the blood on the ground, but accidentally splashed a little on the window glass, while he used the sleeping bag inside to load the jeep owner inside......

What happened after that was what Ye Feifei saw outside, the middle-aged man buried his sleeping bag in the dirt.

The sleeping bag will not be transferred in the short term, and Ye Feifei still has the opportunity to understand the purpose of the middle-aged man in advance, maybe he is an undercover agent sent by the shopkeeper.

Of course, this is all speculation, and it is not yet known whether this is the case or not...... As long as he continues to investigate one thing, he can prove whether his guess is correct or not.

In order to hide the smell of blood, middle-aged people will definitely pour gasoline or diesel fuel on the corpse, as long as Ye Feifei can dig into the sleeping bag and smell whether there is gasoline or diesel in it, he can confirm his guess.

The fuel tank of the jeep has also smelled the smell of diesel, which also indirectly indicates that the car is a car fueled by diesel.
