The wooden tables and chairs in the office were spotless, and Zhan Jingyi tried to open the drawer, only to find that it was not locked, and it was full of thick ledgers.

Zhan Jingyi took out a few copies of it and checked it carefully, the content in it was not complicated, Zhan Jingyi looked at it for a while, and there was a mention of a conversion rate in it, which attracted Zhan Jingyi's attention.

It seems that the main role of this factory is to use the machine to directly refine the energy in the ore and turn it into a synthetic energy crystal, but the conversion rate is not high, according to the records inside, it is about 47%.

In other words, only half of the energy in the ore is converted into energy crystals, and the rest of the energy is emitted as black smoke.

"Strange!"

After looking at a few more account books, Zhan Jingyi noticed that normally speaking, since these energy crystals were mined here, it must be hoped that more energy crystals could be produced, and only in this way could it be in line with normal logic.

But according to the records of these account books, the conversion rate of this energy has not only not increased year by year, but has been declining year by year, from the highest 69%, and on the latest ledger, the conversion rate has dropped to 40%.

In this way, it is somewhat interesting, this conversion rate not only does not increase, but seems to be actively decreasing?

Seeing this, Zhan Jingyi's eyes were a little puzzled, such a move seemed to show that this mining area was not pursuing profits at all, but is this possible?

After checking all the ledgers, Zhan Jingyi didn't find anything special, so he continued to rummage in other places in the house, hoping to find new clues!

……

"Squeak......

At this moment, there was a slight sound of the door shaking, which made Zhan Jingyi's action of rummaging through the items suddenly pause, his body did not move, and he squinted and turned his face to look back.

I saw that the door didn't move, but Zhan Jingyi could hear a trivial sound outside the door, very slight, as if he was deliberately lowering his body, and this sound was particularly clear in the quiet environment.

Zhan Jingyi narrowed his eyes slightly, slowly put his body against the door lock, squinted his eyes and looked out through the door lock, and it was only pitch black at first, swallowing all the light like an abyss.

But as Zhan Jingyi looked carefully, his eyes gradually adapted to the dark environment in the door lock, and he saw that behind the door lock, a black eye was staring at him quietly through the door lock, flashing with a strange and deep light.

This eye seemed to carry some kind of unknown fear, which made Zhan Jingyi's heartbeat accelerate instantly, and the blood rushed rapidly in the blood vessels, making Zhan Jingyi's heart tighten, and he felt that his scalp was numb for a while.

Imagine if you were at home and suddenly heard a sound outside the door, and you looked through the door and saw one eye staring at you coldly.

Subconsciously, Zhan Jingyi flew up and kicked up through the door, and under the power of Zhan Jingyi, the door was like a piece of paper, and Zhan Jingyi kicked out a big hole.

However, the shadow behind the door reacted very quickly, just dodging sideways and dodging it lightly, and then quickly ran towards the back.

Seeing the black shadow of the escape, Zhan Jingyi woke up after a brief loss of consciousness, pushed open the door and chased after him, whether this was a human or a ghost, Zhan Jingyi had a very strange feeling, maybe this guy was the key to solving the puzzle.

The sound of "bang......" hurried footsteps became louder and louder.

Zhan Jingyi's pace was like the wind, and as soon as he stretched out his hand, he grabbed the black shadow, but he saw that the black shadow in front of him suddenly flashed to the left, causing Zhan Jingyi's hand to be empty.

"Damn it!"

With a miss, Zhan Jingyi stomped his foot, his body accelerated and rushed up, and when he was hesitating whether to use his mental power, a black shadow suddenly rushed out from the corner.

……

It happened suddenly, and Zhan Jingyi didn't even have time to dodge, but he reacted quickly and smashed it head-on with a backhand punch.

After a muffled sound, the other party didn't seem to show weakness, and buckled Zhan Jingyi's shoulder with one hand, jumped up, raised his foot and hit it with his knee.

"Bang bang bang!"

Three punches and two kicks, after a short fight, Zhan Jingyi's face was punched twice, the corners of his eyes were cracked, his brows were furrowed, and there was murder in his eyes.

As soon as his mind moved, his spiritual power burst out, and a spiritual storm swept towards the black shadow.

"Holy Light Slash!"

Almost at the same time, the other party also shouted, and the strong light made the light in front of the two of them suddenly light up, Zhan Jingyi and Song Liangliang were stunned for a moment, and said in unison: "Why are you!" ”

"How did you end up here?"

Zhan Jingyi dispelled the storm of spiritual power, took half a step back, and distanced himself from Song Liangliang, his eyes couldn't help but become vigilant.

In fact, from the beginning, he didn't like Song Liangliang to come with him, even if he knew that he was an honest man, but Zhan Jingyi knew since he was a child that trusting this thing was the cheapest.

Song Liangliang was stunned for a while, then took out a flashlight from his waist to illuminate the surrounding darkness.

After making sure that it was the sous chef in front of him, he let out a long breath and explained, "No, I just heard a movement from your side, and I came up, but as soon as I came out, you smashed it with a punch, almost breaking the bridge of my nose." ”

Song Liangliang rubbed his nose with his hand as he spoke, and a holy light technique cleaned up the wound on the bridge of his nose.

"That's it! Did you see anything else? ”

"Something else? What else? ”

Song Liangliang shook his head blankly when he heard Zhan Jingyi's question, he rushed over when he heard the movement, and as soon as he came over, he was beaten, and he really didn't see anything.

After listening to Song Liangliang's explanation, Zhan Jingyi was a little skeptical, and his eyes were always staring at the look on Song Liangliang's face, but looking at his actions and words, it really didn't look like he was lying.

"Did you find anything?"

Zhan Jingyi's muscles that had been tense slowly relaxed, and he asked Song Liangliang.

Nodding, Song Liangliang turned around and took out something from his backpack and handed it to Zhan Jingyi, Zhan Jingyi took it and took a look, it was actually canned, this kind of canned food Zhan Jingyi had not only seen, but also eaten.

This kind of canned food is the kind of canned food that God left for himself when he brought people to see him before, and the one in front of him is exactly the same as the one God gave him, but it is empty.

Zhan Jingyi wiped the edge of the can with his fingers with some doubts, and the wet oil stains inside were very fresh.

"I just found out, two, both of them have just been taken apart!"

Hearing Song Liangliang's words, Zhan Jingyi immediately thought of the two footprints on the ground when they came in before, plus the empty cans under them, which couldn't help but cover the hearts of the two with a shadow.

After thinking about it, Zhan Jingyi also told Song Liangliang about the problems he found in the ledger, and the two of them should go to the first floor to see, where the ore is refined, maybe there will be an answer.

However, just as the two of them were about to go downstairs, Zhan Jingyi's ears suddenly moved, and he reached out and grabbed Song Liangliang's arm, signaling him not to move!

Song Liangliang: "??? ”

"Shh

Zhan Jingyi motioned for him not to make a sound, pricked up his ears and listened carefully, they were standing in the downwind position, as long as they listened carefully, they could hear that there seemed to be a very strange sound in the wind.

Zhan Jingyi didn't know how to describe this sound, but it was a bit similar to the friction sound of a snake crawling on the ground, and slowly, the sound gradually became clearer.

"Everyone, please support if you like, if you don't like it, please let it go! Thanks!"
