Genius remembers in a second [Aishang Novel Network biquge.info] to provide you with wonderful novels to read.

There are two pieces of paper in the drawer, which are obviously clues to the puzzle given by the system. Feng unfolded the first sheet of paper, and three lines of hints were written in scribbled handwriting, the first line was JMMJAOD, the second line was 1/4F, and the third line was 3/4F.

Feng Bujue glanced at it and disdainfully "cut ......".

The second piece of paper is more informative, this is a printed text jiàn, the text on which is very neat, with a detailed description of the virus.

First of all, the code name of this virus is indeed "Z", since this name is also mentioned in the description of the blood wolf zombie at the beginning of the script, it seems that the monsters on the road and the people in this research institute should be infected with the same virus, but why they become different varieties of zombies is unknown.

Secondly, the virus has less than three hours left for the player to be released. The text reads that within three hours of infection, flu-like symptoms appeared, with high fever and severe dementia in the later stages. This explains why Feng Bujue is in a cold sweat all over his body at the moment, and he feels a little weak in his limbs. Obviously, the system can't show the player signs of "severe dementia", so when the virus starts to affect the brain, the player should be considered dead and leave the script.

This is followed by a detailed description of the mutations in the infected person, such as sporadic cell necrosis, which produces localized gangrene symptoms; The oxygen storage capacity of red blood cells increases, slowing down blood flow and increasing muscle endurance and strength; Weakened cognitive abilities, trying to ingest the flesh and blood of living people, etc...... Of course, there is one last rule - suppressing the completely infected requires extremely strong cranial trauma.

After reading this paragraph, Feng Bujue couldn't help but say, "Isn't this SCP008...... But...... There is actually antivenom in the setting of this script. As he said this, his eyes fell on the last paragraph about serum.

The paper reads: "The truth shows that antivenom is not effective for everyone. In 390 cases of different genders, ages, blood types, and races, a total of 154 people were immunized or relieved of the effects of the virus after being injected with serum. The probability of serum response is slightly less than 40%, and no clear pattern has been found for serum response or not. ”

After reading this article, Feng Bujue gradually felt that it was not good, and in terms of his character, the probability of detoxification failure was self-evident...... Even if you find the serum, there is only about a 40% chance that you can remove the [Disease] state. Otherwise...... He only has two hours left to use, and it is unlikely that he can clear the level in this time, and the biggest contribution he can make is basically to find the serum and give it to his other teammates.

Speaking of teammates...... Ten minutes ago, when he heard the news of the death of Young Master Jibe and Xiao Ming in the corridor, he already understood that this script was far from as simple as it seemed. The death of the two was very puzzling to him, they didn't look like the type who would leave the gun shop without permission to look for trouble. So they died one after another in a short period of time, and it is very likely that they encountered some kind of very powerful monster directly at the door of the gun shop.

But how could there be such a monster in a place in the city that has nothing to do with the main quest? Even at night, when the Blood Wolf Zombies are strengthened and swarmed up, they won't be able to kill two players with submachine guns at the same time in a matter of seconds.

In addition, Pan Feng and Hua Xiong, who were with Wang Sizhi, also made Feng Bujue feel a little strange, judging from the current situation, after the two of them entered the building with Xiao Si, they did not come to this underground research institute, but went to other places. Why is that? There is such a large sign standing in the lobby on the first floor, and the main quest is clearly written to save a "doctor". The other floors are marked with a mess of departments, or simply the words "office area", so that people will go upstairs to find it?

There are too many abnormal circumstances, and there is no evidence for the time being, Feng Bujue didn't continue to think deeply, he turned around and walked towards the metal gate, leaning over to look at the combination lock on the gate.

"Sure enough, it's six digits......" He looked at the operation disk that entered the password, with a look of "as expected", and directly entered the 312928, but he didn't expect that after he lost, the word accept really jumped out of it.

The meaning of this puzzle was understood by Feng Bujue when he saw the paper. The JMMJAOD in the first row represents the initials of the first, third, fifth, seventh, eighth, tenth, and December, all of which are 31 days; And the F in the second and third lines represents February, only the initial letter of February is F, 1/4 represents the 29 days of February in leap years, and 3/4 naturally represents 28, this kind of puzzle is really not difficult for him, he himself is a person who often has to conceive puzzles, write clues on paper and give them to him, as long as the knowledge required to solve the puzzle is not beyond his ability, most of them can be figured out quickly.

After unlocking it, Feng Bujui grabbed the hand valve on the gate, turned it a few times, and then opened the door. Inside, a relatively small room, three walls filled with transparent cabinets filled with test tubes containing liquids, each row labeled to indicate their number.

Pick up the tube and you'll see the description of the item:

[Name: Antivenom Serum]

[Genre: Drama related]

[Quality: Normal]

[Function: 39.48% chance for the user to remove and be immune to the effects of the Z virus]

[Can I bring out the script: No]

[Note: It can be injected or drunk, and it is not effective against monsters and players who are completely zombies]

Looking at the number, you can deduce that these serums are made in batches, and perhaps the composition will vary. Feng Bujue couldn't help but think at this time, maybe this Z virus was not developed by the Aileb company, they just found it and controlled it, and tried to develop a method of detoxification?

Feng Bujue didn't care about studying the company's position for the time being, he didn't know which batch of these serums was more effective than which, so he just took one out of the cabinet casually, drew a tube with the syringe he just found, and gave himself a needle.

When this injection goes down, his medical specialization will be turned on and he will become F-level, and the system prompt will sound: [Congratulations on unlocking all the qualifications in the closed beta phase]

"Closed beta?" Feng Bujue said in his heart: "In other words, there will be new specializations in the future?" He opened the game menu and saw that the specialization column was fully open, which was a good thing, but unfortunately...... The [Disease] status next to the Survival value still does not disappear.

"Did it fail......," he read with some disappointment, "or do you want to do another one?" I don't know if there will be any side effects......"

Just as he hesitated, the word illness in the menu disappeared, and the ailment next to the survival value changed again: [None].

It's a good thing he didn't close the menu immediately, otherwise it would have been possible to ignore this slightly delayed change, and the guide would have another shot somehow or something. Feng Bujue immediately laughed three times, and suddenly had a feeling of coming back to life.

He took out a rack of test tubes from the freezer with two rows of eight antivenoms. He carefully placed it in his bag, which was now fully stocked: Mario's Pipe Wrench, Haunting Eye, Western Kitchen Knife, Baseball Bat, Flashlight, M1911A1 Pistol, Echo Armor, Winchester Shotgun, Anti-Venom*8, and a Bag of Garlic.

Jazz dancing is on the feet, and unless it is replaced, it is unlikely that it will return to the bag. Of course, if necessary, as long as he took out the Eye of Hatred and put it on, and held another weapon in his hand, he could also make room for his bag.

After the serum took effect, Feng Bujue no longer needed to continue to explore the institute, he originally came down to find his teammates, he never expected that he would be hit as soon as the elevator door opened, and he didn't know the specific mutation time when he was first infected, so he could only search for the serum that might not be stored as soon as possible.

And now, since he won't die due to the time factor, he thinks it's better to go back to it and find his teammates first. Considering that I have bought the serum, I may not know what FLAG will be triggered, and if I don't do well to explore further, I will have to meet the mini-BOSS, who is already immune to the virus, and it is not worth the risk at this time.

Just as he was thinking this, a system prompt sounded: [The current task is complete, and the main quest has been updated]

"What?" Feng Bujue was very surprised: "Could it be that Dr. Ashford is really not underground?" Did the three of them go upstairs on the right foot, and have already managed to get the doctor out? ”

He hurriedly opened the menu to see what the mission had been updated after rescuing the doctor, but the task turned out to be: [Defeat Ashford's mutant]
