Under the leadership of the soldiers, Qi Lin, Cheng Yanqiu and the heads of various consortia walked into the laboratory together, only to see that the laboratory was in a mess, full of overturned glassware and research instruments, in the largest room, all the corpses were carried to the corner of the wall and lined up, covered with pieces of white cloth, as for the parasitic worms taken out of the corpse's brain, they were all soaked in a wide-mouth reagent bottle filled with formalin solution.

"It's a mess in the lab, but the perpetrator has erased all traces of himself in a very old-fashioned way, whether it is footprints or fingerprints, all we can find is the ones left by the deceased, and as for the bullets, all of them are nine-millimeter parabellum bullets made in the old era, which are easy to find in abandoned cities, so we can't deduce the identity of the owner of the bullet."

The man who spoke was a tall, muscular black man named Peyton, the first unit commander to arrive at the lab.

Qi Lin walked over to a corpse and lifted the white cloth that covered it.

This is an elderly scientist, whose skin has shown the same state of alienation as it was after being parasitized, and in order to remove the parasitic worm in his brain, his head has been split open, and the brain inside has also been removed.

In addition to his head, the scientist had only one wound - a nine-millimeter Parabellum bullet pierced his kneecap, leaving him without the ability to escape.

"This was originally the fate that those people prepared for us......" Qi Lin looked at the deceased's distorted face and covered the white cloth back.

"They moved quickly, not only killing everyone in the lab, but also completely destroying the mouth with the help of parasitic worms, which happened at about the same time as the attack we had at the bar." Cheng Yanqiu said.

"Whether the attack is successful or not, these people will definitely be wiped out, and even if we die, the parasitic worms will still be found here." After Qi Lin finished speaking, he looked around the entire laboratory, hoping to find some useful evidence.

"Is there any surveillance record? Even if the surveillance camera is destroyed, the records from the previous days should still be there, and there are some clues that can be found. Cheng Yanqiu turned his head and looked at Peyton.

"The hard drive of the computer connected to the surveillance camera has been pierced by bullets, and although we have taken it to repair, the chance of recovery is very low, less than one percent." Peyton shook his head and said.

"Paper records! That's right! Qi Lin stood up suddenly, "This kind of laboratory entry and exit visitors will definitely leave a paper record, this record has two copies, one is kept with the security guard, and the other should be in the archive room!" ”

Qi Lin's mercenary group once took over a mission in North Africa to take charge of the security of an infectious disease research institute for three months, during which time every visitor who was not a member of the research institute had to leave a record of their visit.

Even this institute system is so strict, let alone the laboratories used to study parasitic worms.

Qi Lin and Cheng Yanqiu immediately divided into two ways, Cheng Yanqiu took a group of people to the archives, while Qi Lin ran to the doorman.

Running to the gate of the laboratory in one breath, Qi Lin opened the guard booth, and as soon as he opened the door, a faint smell of burning came to his nose - he saw that the thin interview record sheet had all been burned by someone with fire, and as soon as the wind blew, the ashes flew in all directions.

"Damn it!" Qi Lin scolded secretly, and had to go back to the laboratory again.

But fortunately, Cheng Yanqiu found a copy of the visit record in the archives - it seems that the other party was negligent in the end.

This visit log shows that in three days, a total of 16 times, a total of 19 outsiders entered the laboratory and left, of which 13 were to deliver daily necessities to the laboratory, twice were by members of the Rentai Foundation to deliver research equipment, and the only private visit record shows a person with the ID "Raven".

It's an English word for "raven", but it also means something else, "to plunder".

"What's the origin of this guy? Check it out. Qi Lin pointed to this ID and said.

……

It didn't take long for someone to investigate the origin of this "Raven", a powerful evolutionary whose strength had reached level 3, and his identity was a free mercenary who had direct contact with Kuroshio in the frontier positions in the border area, and was also one of the few players who was able to escape from there.

However, this is not the key, the most critical point is that nearly half of the parasitic worms in the laboratory of the consortium alliance are captured by this "Raven" and sold to the laboratory.

Two days ago, Raven came to the laboratory to settle the final payment for the purchase of parasitic worms with the people in the laboratory, but what made Qi Lin a little puzzled was that Raven stayed in the laboratory for three hours before leaving.

The lab wasn't huge, and it wasn't as bloated and inefficient as some of the administrations of the old days, so it shouldn't take three hours to settle the final payment.

"This Raven...... There must be a problem, is he in the base camp now? ”

"I don't know, for this kind of free mercenary, the management of the alliance is not strict, they have a lot of freedom of movement." Payton shook his head.

"If you can, lock down the entire base camp right now and find out this Raven! It is very likely that these six parasitic worms were taken out of the laboratory by this Raven, and finding Raven is equivalent to finding the mastermind behind this murder plan! ”

"It is a bit difficult to block the entire base camp, but we can issue orders to the exit checkpoints, so that they can arrest this person immediately after discovering him, and at the same time, we will also send people to search for the traces of this person in various taverns, mercenary guilds, hunters' guilds, and commercial areas in the base camp, and once they are found, we will notify you as soon as possible." Peyton said in a deep voice, though he left the lab with a group of men.

"Let's not be idle, Cheng Shao, you'd better rush back to the station of the Cheng Consortium now, and stare Ning Han and his people to death, while Hans and I go to the street to find that 'raven' - even if it's looking for a needle in a haystack, as long as this needle is still in the base camp, I have a way to fish it out!"

Now that the entire permafrost tundra, except for those areas where the rebels are active, almost all the players in the alliance camp are concentrated in the base camp, and that Raven must be hiding in a corner somewhere, quietly waiting for the limelight to pass.
