Withdrawing his gaze, Li Fu began to look at the building in front of him.

Documents and files littered, a few cracked old computers, and overturned chairs.

After following the flashlight back and forth, Li Fu probably knew where he was, and this should be the accounting office of the factory.

"Bone ......"

Li Fu raised his foot and prepared to go over to search for it to see if there was anything that could be used, of course, this thing was best a battery, but as soon as he raised his foot, he kicked an object on the ground.

The flashlight hurriedly swept down, it was a glass, and there were some black dark slags at the bottom of the glass, which should be rotten tea leaves.

Retracting the electric light, Li Fu glanced at the doorway on the opposite side, which no longer had a door, and there was a faint sound in the distance, which was the echo from the glass just now when it was rolling.

After standing there and listening for a long time without hearing any other movements, Li Fu began to rummage gently in this not small accounting room.

A drawer was opened, and there was nothing useful to Li Fu in it, except for a few broken reports.

Another drawer was opened, and there were still some reports and stuff in it.

……

Time passed slowly, but the sound of water droplets not far away was like a spell, slowly tormenting Li Fu's ears, and Li Fu, who had found nothing, once again shone his flashlight towards the dark door.

"There's nothing, it looks like it's going to go out!"

At this time, the light of the flashlight was getting dimmer and dimmer, and the outline of the place ten meters away could no longer be seen, so Li Fu had to continue to walk forward.

However, as soon as Li Fu stepped out of the door with his left foot, he immediately took it back.

"This thing might work."

Finding the glass that he had just ignored, Li Fu picked up the glass and unscrewed the stainless steel lid, carefully found a relatively large puddle of sulfuric acid, took about half a bottle and walked back.

Carefully wiped some of the sulfuric acid on the surface of the glass with paper, Li Fu looked at the small half bottle of sulfuric acid water, and screwed the stainless steel cup lid with satisfaction.

It's a little inconvenient to keep the glass in your pants pocket, but it's better than holding it.

But Li Fu turned back again, and took out a pencil and a palm-sized notebook from the drawer.

Circled a dot in the center of the notebook, Li Fu, who stepped out of the room, looked at the two roads in front and back of the corridor, and walked in the direction to the right with a roll of his eyes, and on the point on the notebook just now, a folded line to the right was also extended.

I don't know how long I walked, anyway, Li Fu didn't see a single person, and he didn't find a battery.

"Bang Bang ......"

Li Fu, who was still drawing along the way, raised his head suddenly, because there was a sound of steel hitting the ground in front of him.

Without the slightest hesitation, Li Fu hurriedly ran towards the place where the voice came from.

However, the sound came and went quickly, and before Li Fu's ears could catch the specific location of the sound source, the echo disappeared in the distance.

"Woo...... Woohoo......"

At this time, the little black dog, which had been shrinking in Li Fu's arms, whimpered in a low voice in the direction to the left.

"Over here?" Li Fu looked at the little black dog that whimpered and said.

The little black dog looked at Li Fu with big watery eyes.

"Okay, let's go this way!"

Li Fu still believes in the judgment of the little black dog, after all, aside from the other abilities of the little black dog, in terms of its dog characteristics alone, it is also many times better than human hearing, judging the source of sound, human beings can not be compared with animals.

Of course, in the case of human beings not using technology.

Walking cautiously to the corner of the corridor and stopped, Li Fu looked up at the sign of a man and a woman on the door plate above, and knew that this was a bathroom.

Li Fu looked down at the little black dog, and the little black dog blinked a few times.

Without being verbose, Li Fu gently pushed open the door of the hidden bathroom.

Inside is a passageway, and on both sides of the corridor are men's and women's toilets.

The direction of the little black dog's face was the women's bathroom, Li Fu glanced back at the entrance of the men's bathroom, and walked towards the women's bathroom.

Before entering the bathroom, Li Fu smelled a faint smell of blood, which made Li Fu immediately extinguish the flashlight in his hand.

Li Fu's senses were immediately invaded by darkness, and he almost couldn't see his five fingers.

Feeling the coldness coming from the wall, beads of sweat oozed from both sides of Li Fu's forehead.

"There shouldn't be any ghosts here, or the little black dog wouldn't have given a warning at all."

After thinking about it for a long time, Li Fu still felt that he had to take a risk, otherwise when the battery in his hand ran out, it would be his real end.

Turning on the flashlight again and looking at the dim pillar of light that stretched less than three meters away, Li Fu was even more determined to go in and take a look.

The unknown is the most terrifying, although Li Fu has experienced the world of ghosts twice, but the human instinct of fear of darkness and the unknown from ancient times still makes Li Fu's back wet with cold sweat again.

"Whew~"

Taking a deep breath, Li Fu suddenly turned around and swept the flashlight inside.

A male corpse was lying on the sink with his back to Li Fu, and the bright red blood was still slowly sliding from the edge of the sink to the tiles on the ground from time to time.

Around the man, there were also several steel pipes that had been cut diagonally with broken wounds.

Li Fu took his eyes off the corpse that seemed to have just died, swept around the compartment inside, and found that there were no other abnormalities before slowly walking in.

When he came to the male corpse, Li Fu knew the cause of the man's death.

A rusty steel pipe was stuck in the man's head, blood gushing out desperately from the cracks in the wound, not at all nostalgic for the mother who had been giving birth to it for decades.

Li Fu looked up and saw that the iron barricade located in the upper vent was nowhere to be seen, and only a few crumbling thin steel pipes were still hanging on the edge.

"Battery!"

Li Fu suddenly found that the corpse was holding a battery in his right hand, and another battery was lying quietly on the drain in the middle of the sink.

A hint of surprise flashed on Li Fu's face, and he secretly said that there were really good things here.

However, Li Fu's outstretched hand immediately retracted.

Relying on the dim light, Li Fu finally found the cause of this person's death.

On the battery in his hand, a transparent thin wire is being tied, and when he looks down the thin wire, the other end of the thin wire is tied to a steel pipe on the ground.

Li Fu glanced at the flashlight on the man's left hand, turned it on and saw that the bulb of the flashlight was on and off, which was obviously a prelude to the battery having completely run out.

It seems that this person found this place in the last period of time when the flashlight ran out, and found the battery on the sink, but he didn't see it in a hurry, and there was a thin wire connected to the sharp steel pipe on the vent on the battery.

As a result, when he picked up the battery, thinking that he could see the light again, he didn't expect that he would be greeted by endless darkness.

Since there was no more danger, Li Fu took the battery from the man's hand, and then picked up the battery in the sink.

At this time, the flashlight in Li Fu's hand had begun to flicker, and Li Fu hurriedly removed the back cover and put the new battery inside.

"Smack!"

The flashlight returned to its original light, but Li Fu looked at the battery he had just replaced, but there was no smile on his face.

Based on the use of these two batteries, the batteries in the flashlight must be replaced every half hour.

It also means that in another half an hour, Li Fu will face the danger of running out of batteries again!

Temporarily putting aside the thoughts in his mind, Li Fu searched the bathroom carefully for a while, but found nothing else useful.

Every second that passed at this time was a countdown to death for Li Fu, and since he didn't find anything else, Li Fu hurriedly walked outside.

"You must find the next two batteries in twenty minutes, otherwise you can only wait to die or be killed by the trap set by the crew in this dangerous and dark place!"

Li Fu wouldn't believe that the crew would pick people up after a day, there is only one way out by yourself except for you to go out by yourself.

Die!

"Woo...... Woohoo......"

Just as Li Fu was about to go to the men's bathroom to search, the little black dog in his arms suddenly whimpered in the direction of the left.

Li Fu hurriedly lay on the ground, put his ears close to the ground, and sure enough, he heard a slight sound of footsteps not far in front of him, and there was more than one person listening to the sound.

Outside is the corridor, which means that Li Fu will be seen as soon as he goes out.

Li Fu, who didn't know whether it was friend or foe outside, turned around and walked towards the women's bathroom that had just come out.

However, there was no place to hide in the women's bathroom, and Li Fu's eyes couldn't help but look towards the vent on the sink......

"The voice just now should be around here!"

Outside the bathroom, a delicate female voice was heard.

"Yes, and there's a faint smell of blood here." A man's deep voice was heard again.

However, the voices of both of them were low, obviously deliberately suppressed.

Li Fu, who was already lying on the vent, moved his body back again, and after about ten seconds, the entrance to the women's bathroom was illuminated by a pillar of light.
