The fourth level biosafety laboratory is the highest level of high-risk biochemical laboratory.


    LINGJI, farreid and others successfully found P4 laboratory, which is located at the bottom of the Arctic laboratory base.


    The laboratory consists of changing area, filtering area, buffer area, disinfection area and core area.


    The inside of the laboratory is equipped with high efficiency air filter, which is made of glass and steel. You can see everything inside.


    To reach the core area of the laboratory, you must pass through 10 doors. The innermost 7 doors are interlocked. In other words, if one door is not closed, the other cannot be opened.


    After stopping Linggui from breaking through the first door of the laboratory, farreid steadfastly picked up the internal communication device on the wall on one side of the glass sliding door, gave LINGJI a "rest assured" look, then he said coldly in English: "listen up, come out by yourself, or you will die in it. If you resist, you will be lenient. You will be given 20 seconds, Now the countdown begins 20、19……”


    The alarm on the whole floor was extremely harsh, and farreid''s cold countdown was even more frightening.


    When he counted down to three, the gas valve opened.


    Four laboratory researchers ran away in panic. They were just the last one. They were quick and quick. They grabbed the back neck as if they had grasped the key of fate. They took off the mask and pulled off the sterile cap. She was a foreign woman with fair hair and blue eyes. She was the director of the fourth level laboratory. She was a biological gene scientist.


    "Take us in." The ghost and the shivering woman look at each other, and their eyes are cold as death gaze.


    In Linggui''s eyes, these scientists who do research are "incompetent people" who have no power to tie a chicken. Of course, she means that most of them are, and there must be a few "hard bones".


    For example, this one in front of you.


    The blonde woman is constantly crying and screaming for mercy, trying to distract the mind.


    At the time when Linggui showed a bored look and her vigilance was a little lax, the blonde woman suddenly showed a fierce look. From the pocket of her white coat, she took out a transparent injection like lightning and stabbed it hard at the arm of Linggui!


    At the moment when he wanted to pierce into the skin, Linggui was at a commanding position. He broke the wrist bone of the woman''s hand with his backhand and seized the injection in her hand. Then he firmly grasped the needle cylinder in the lost hand and held tightly the palm of the hand to ensure that the liquid in the syringe would not leak or flow out due to the breakage of the syringe.


    "Cats and dogs want to hurt me these days." Disdainful sneer, LINGJI will surrender the woman to farrid, the syringe to Adele, "take care of it, the things inside may be infectious virus and so on, don''t break it."


    Farid snatched the woman''s access card, and borrowed the woman''s iris and fingerprints to pass through the first and second biosafety doors.


    The screams of women in agony reverberated through the laboratory.


    The alarm outside was still harsh.


    The spirit of the mat behind, protect the front of the people.


    And just as farryd was about to enter the third safety gate, suddenly! A huge iron axe flew in the direction of the spirit and the crafty, and "bang Dang" was embedded in the sterile wall between the second door and the third door.


    - "P4 laboratory is damaged, P4 laboratory is damaged, please evacuate immediately


    Shocked by the sudden blow of the axe, LINGJI suddenly looked back, and saw a tall and powerful old man, such as a domineering and cold-blooded geshiwu man, with a rocket launcher on his left shoulder, a bullet bag with thousands of bullets on his right shoulder, and a heavy machine gun in his right hand, which destroyed a wall in a murderous manner, and walked towards the ghost coldly and mercilessly.


    Farid looked back. At the moment he saw the old man, his dark green pupils shrank as if he had seen the devil.


    "He is alsoregon."


    Hearing the sound, he pulled out the axe embedded in the wall with one hand, and his beautiful eyes were filled with excitement. "You two protect the old Shennong to destroy all the viruses. Here I will deal with it."


    After closing the third moving door and the second moving door to ensure that farreid can enter without hindrance, Linggui waves his iron axe, spins his body 360 degrees and throws the axe back.


    When the iron axe was about to hit sulegan''s neck, in an instant, the old man put down the rocket launcher in his hand, and a mysterious black crystal substance grew in the palm of his hand. As soon as the material touched the iron axe, it immediately decayed and turned into a pile of iron filings.


    Then, the black crystalline material in his hands disappeared, and he raised the rocket again toward the ghost.


    Aim at the smart and pull the trigger of the launcher without hesitation.


    "Whoosh" to a sound, rocket launcher launch, unstoppable toward the spirit of the rapid!


    The response time is only half a second.


    Behind him is the P4 biochemical laboratory. Seeing the fire arrow barrel rushing towards him at a high speed, the spirit and the devil suddenly whirled around and chanted a seal. A black purple spell seal expanded infinitely in an instant, forming a huge boundary, which protected the biochemical laboratory. At the same time, Linggui held the dark pearl in his hand and turned into a transmission channel leading to the ground.The Rockets roared in from front of them and disappeared into the passage, which was closed.


    "Who are you?"


    A series of measures to deal with the problem, let the domineering old man''s eyes show a dark look.


    In French English, the old man threw the launcher in his left hand and held up a machine gun in his right hand towards the ghost.


    "Dead people don''t deserve to know."


    The spirit is very beautiful, proud of standing there, standing still, side, a hand in the back, hook lips a smile, arrogant way.


    -


    at the same time, farreid, Adele and Shennong, who had entered the core area of P4 laboratory, dragged half dead researchers to search for the virus samples that caused massive death in the laboratory.


    The core area is equipped with high-end advanced and expensive equipment, such as biosafety cabinet, ultra-low temperature refrigerator, centrifuge, electric heating cell culture cabinet, microscope and laboratory, small animal laboratory, etc.


    On the top of the biosafety cabinet, there is a thick pipe with a diameter of about 0.5 meters, which directly leads to the roof. It is also under negative pressure. Some major operations need to be carried out in the biosafety cabinet. There are also some pipes that deliver oxygen into the sterile clothing.


    But farryd, they didn''t come in dressed.


    "Which one is it?"


    Shennong was standing in front of the ultra-low temperature refrigerator, looking at the colorful test tubes and virus cells in the cell culture cabinet. He was an old fairy, and he seemed a little impatient about the things he had never seen before.
