After climbing four floors in a row, he saw almost nothing in front of him except for the cluttered desk.

It is as if the entire floor is a place for regular clerical offices.

But......

"It's strange...... Zou Xia walked to the nearest desk and picked up the bread that had just had time to unpack, the bread was already covered with gray-green fluffy mold, poked open the mold, and the bread inside had turned into a sticky, wet and slippery unknown object like a hot rice cake.

"Putting aside the traces of time, they seem to be working like normal employees one moment ago, eating breakfast, and dealing with documents and files, but the next moment they all withdrew from the company, so hurried that the documents were not sorted out, and they ate breakfast halfway, and they didn't have time to throw it away or take it away...... It's like an emergency evacuation, yes, it's like an emergency evacuation! ”

But there have been no major natural disasters in Los Angeles in the last two years......

Zou Xia transferred a stool and sat down.

All kinds of possibilities keep flashing through my mind,

And why are they in such a hurry?

It's really seen something terrible,

Or the order to abandon the building, which was given suddenly without warning, under the leadership of senior leaders, so that the employees did not have time to deal with these debris.

Just as he was thinking, Jenny's voice suddenly interrupted him: "Chief, come and see, this pool is red with blood, right?" ”

In order to avoid revealing their true identities, the team is rarely referred to by their real names, either as a spy code name or as a team position.

Hearing Jenny's voice, Zou Xia quickly got up from the stool and patted the ash on her buttocks while moving closer to Jenny's place.

Jenny crouched in a corner, her eyes repeatedly surveying the dark red of paint on the floor.

Dried blood, odorless, dark red seeping into the ground.

It's not as easy to judge as fresh blood.

Zou Xia looked at it carefully for a moment, then looked away, looked around a few times, and finally looked at the ground under the desk not far away.

He walked over curiously, stretched his hand down, and picked up a slender white bone, on which there were still dried and moldy shredded flesh.

Zou Xia picked up the white bone, stretched out his palm and measured it twice, its length was slightly shorter than the middle finger, but slightly longer than the thumb and little finger, and it may be the phalanx of the index finger and ring finger.

Of course, it cannot be ruled out that the owner of this finger bone has very few exceptions with abnormal finger development.

In the natural environment, human bones and animal bones are still easily distinguished without being considered destroyed.

"The case has been solved, it is human blood!" Zou Xia threw the human bones on the bloodstain.

However, this human bone made him curious about what happened in this office when his finger was broken.

The fracture of that phalanx bone doesn't look very normal.

Normally, there are two types of severed fingers: 'severed by sharp props, along with flesh and bones', and 'broken by external forces, and broken by crushing finger bones'.

The cross-section of the former's phalanges will be flat,

The latter's phalanx bones will be broken into several pieces, and even the belt flesh will be flattened, and the leg will have to be amputated.

But it was clear that the phalanx did not fit any of the above conditions.

The cross-section of its fracture is very uneven,

It's kind of like being squeezed by two handfuls of thin, sharp serrations.

Other details on the joint phalanx,

Zou Xia quickly came to a bold conclusion: this finger should have been gnawed off by something!

The reason is in that phalange!

It is not flat, but is covered with small pits that resemble sharp and small pits in cross-section.

It was supposed to be some kind of tooth bite on a human bone......

Although Jenny couldn't analyze something in such detail, she still noticed something unspeakably strange, and she was so frightened that she quickly left the dry blood stall and hid closer to Zou Xia.

On this floor, the two of them did not stay long, but continued to go up.

However, in the middle of the stairs from the 4th to the 5th floors, there is a very strange phenomenon, there is an iron door in the middle of the stairs, the iron door should be locked, but now it is opened by something......

On the staircase next to it, there is a chain of locked iron chains, which are broken from the middle, and the fracture is very complete.

Something broke through the door from the outside, went into the iron door, and then closed it from the inside! ’

Zou Xia easily restored the truth.

But not afraid, he smiled, pulled the door open, and continued up.

Jenny followed, her eyes lingering on the broken lock on the ground, and then hurriedly stepped up to catch up with Zou Xia's pace.

On the 5th floor,

Finally, it was no longer the usual civilian office scene.

"This is the lab!" Looking at the documents scattered all over the ground, the large dark red spurting blood stains on the walls, the decomposing corpses that rushed to the door, and the several instruments in the room with unknown functions, Zou Xia quickly came to a conclusion in his heart.

"How did these people die?" Curious, Jenny crouched down to examine the corpse of a woman closest to her.

When the corpse was turning, the stench on the top came to the surface instantly, but fortunately, the gas mask could play a role in isolating the smell somewhat.

"Check the information first!" Zou Xia opened his mouth, and then carefully picked up all the documents on the ground.

One by one

In the data, there are several drawings, which should be the design drawings of several equipment, but it is difficult for non-professionals to understand.

However, if you don't understand the text, the diagram is still very easy to understand.

It was a large petri dish similar to that used in science fiction movies to grow clones, a cylinder, filled with a chemical liquid, and the liquid was soaked in a human figure drawn with dotted lines.

"Why the dotted line?"

Zou Xia didn't understand.

But he soon realized a problem, and he successfully found the corresponding equipment according to the design drawing.

All that remained of the device was a knee-high base, and the cylindrical glass cover on which the chemical liquid was held was cracked, shattering the ground all over it.

Zou Xia took the design drawing and compared it with the suspected equipment in front of him.

There is only one question that comes to mind,

"In the blueprints, the chemical liquid was supposed to be soaked in a human-shaped thing, but now it's gone! Among the corpses present, there were only researchers in white coats, and there were no suspected test subjects at all! ”

"So where did the stuff that was supposed to be soaked in a chemical liquid go?"

Zou Xia's face was as usual, and he even hummed a small tune in his mouth, squatted down, and looked at the corpse on the ground like Jenny.

The cause of death of these people is very uniform, almost all of them were bitten to death by something.

After too long, the traces of the bite are difficult to distinguish with the naked eye, but in the bite part, on the bones, there are still indelible, fine traces of sharp holes.

Obviously, the one who bit off that finger downstairs should be the same thing that bit these people to death.

In silence, both of them were thinking, each thinking about a different angle.

However, at this moment, Zou Xia keenly felt that something seemed to pass by the door quickly.

It's incredibly fast,

Zou Xia subconsciously raised his head, and his gaze collided with a pair of beast eyes that reflected light in the darkness!
