Under the leadership of the soldiers, Qi Lin, Cheng Yanqiu and the heads of various consortiums walked into the laboratory together. The laboratory was in a mess, with overturned glassware and research instruments everywhere. In the largest room, all the corpses were carried to the corner of the wall and lined up and 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.

"The laboratory is very messy, but the perpetrators have erased all their marks in an experienced manner. Whether it is footprints or fingerprints, all we can find is the ones left by the dead. As for the bullets, they all use nine-mm Parabellum bombs produced in the old era. This kind of bullet is easy to find in abandoned cities, so we cannot infer the identity of the bullet owner."

The person who spoke was a tall and strong black man named Petton, and he was the commander of the first troops to arrive in the laboratory.

Qi Lin walked to a corpse and lifted the white cloth covering the corpse.

This is an elderly scientist. His skin has shown an alienated state after being parasitic. In order to remove the parasitic worms in his brain, his head has been split open and the brain inside has been taken away.

Apart from his head, the scientist had only one wound on his body - a nine-mm Parabellum bomb penetrated his kneecap, causing him to lose the ability to escape.

"This was the end that those people prepared for us..." Qi Lin looked at the distorted face of the deceased and covered the white cloth back.

"They acted very quickly, not only killing everyone in the laboratory, but also completely wiped out the mouth with the help of parasitic worms. According to time, it happened almost at the same time as the attack we encountered in the bar." Cheng Yanqiu said.

"No matter whether the attack succeeds or not, these people will definitely be silenced. Even if we die, we will eventually be found here when the parasitic worms are scattered." After Qi Lin finished speaking, he looked around the entire laboratory, hoping to find some useful evidence.

"Is the surveillance record still there? Even if the surveillance camera is damaged, the records from the previous few days should still be there. Maybe some clues can be found." Cheng Yanqiu turned his head and looked at Peidun.

"The computer hard drive connected to the surveillance camera has been penetrated by a bullet. Although we have used it to repair it, the chance of it being restored is very low, less than one percent." Petton shook his head and said.

"Paper record! By the way!" Qi Lin suddenly stood up, "A visitor in and out of a laboratory will definitely leave a paper record. There are two records, one is kept in the security, and the other should be in the archives!"

The mercenary group where Qi Lin was located once took over a task in North Africa to be responsible for the security of an infectious disease institute for three months. During that time, every visitor who was not a member of the institute had to leave a visit record when entering the institute.

Even this kind of research institute system is so strict, let alone a laboratory used to study parasitic worms.

Qi Lin and Cheng Yanqiu immediately split into two groups. Cheng Yanqiu took a group to the archives room, while Qi Lin ran to the guard.

He ran to the laboratory gate in one breath. Qi Lin opened the guard booth. As soon as he opened the door, a faint smell of burnt came into his nose. He saw that the thin visiting record had been burned by someone with fire. When the wind blew, the ashes flew everywhere.

"Damn it!" Qi Lin cursed inwardly and had to return to the laboratory again.

Fortunately, Cheng Yanqiu and his team found a copy of the visiting record in the archives - it seems that the other party was negligent in the end.

This visit record table shows that within three days, there were 16 times, and a total of 19 outsiders entered the laboratory and left. Thirteen of them were to send daily necessities to the laboratory, and two times they were from Rentai Consortium to deliver research equipment. The only private visit record was to show a person with an id called "raven".

This is an English word - "raven", but it has another meaning, "robbery".

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

...

Not long after, someone investigated the origin of this "raven". This is a powerful evolutionist with a level 3 strength and is a free mercenary. He had direct contact with Kuroshio in frontier positions in the border areas and was one of the few players who could escape from there.

But this is not the key. The most critical point is that nearly half of the parasitic worms in the lab of the Consortium Alliance were captured by this "raven" and sold to the lab.

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

This laboratory is not large in scale, and the organization is not as bloated as some administrative departments in the old era, and the work efficiency is slow. It shouldn't take three hours to settle the final payment.

"This raven... must have a problem. Is he in the base camp now?"

"I don't know that for such free mercenaries, the management of the alliance is not strict, and they have a lot of freedom of movement." Petton shook his head.

"If possible, the entire base camp will be blocked immediately and the raven will be found! These six parasitic worms are likely to be taken out of the laboratory by this raven. If you find raven, it is equivalent to finding the mastermind behind this murder plan!"

"It's difficult to block the entire base camp, but we can issue orders to the checkpoints at various exits so that they can arrest this person immediately after they find it. At the same time, we will also send people to search for the traces of this person in various taverns, mercenary guilds, hunter guilds, and commercial areas in the base camp. Once something is discovered, we will notify you as soon as possible." Petton said in a deep voice, although he left the laboratory with a team of people.

"We should not be idle either. Mr. Cheng, you'd better rush back to the Cheng Consortium's headquarters and keep Ning Han and his people to death. Hans and I went to the street to find the 'raven' - even if we were looking for a needle in a haystack, as long as the needle is still in the base camp, I will have a way to fish it out!"
