The scalding water fell on the skinners, causing them excruciating pain!

  After losing their skin, the pain was amplified dozens or hundreds of times!

  Although these skinners were confused and crazy, they could still feel the pain. They immediately wailed and dodged the water like wild beasts.

  Shen Feng held a large spray bottle in each hand and sprayed it crazily, creating a water circle with a diameter of three or four meters around him, causing all the skinners to retreat and not dare to approach.

  This thing is much more useful than a pistol or a submachine gun, at least it has no recoil at all.

  After forcing the skinners around him to retreat, Shen Feng had already arrived at the elevator door.

  It was a pity that after several years, although many equipment continued to operate under the support of the solar power supply system, the elevator had been completely scrapped.

  Fortunately, the laboratory he was going to was underground. Shen Feng immediately turned into the entrance of the emergency ladder, spraying water while running down.

  The skinners in the hall did not leave, but followed Shen Feng, keeping a safe distance of several meters, ready to rush forward at any time.

  The situation... is a bit bad...

  After all, boiling water is not a deadly item, and it is difficult to cause real harm.

  And the number of skinners encountered along the way is increasing!

  When the boiling water in the two spray bottles was used up, he had already arrived at the entrance of the third underground floor.

  This is the No. 1 laboratory of the epidemic prevention center, and it is also the place for vaccination!

  The induction door is still running, and it detects the appearance of Shen Feng and immediately opens slowly.

  Shen Feng flashed in and was stunned.

  What appeared in front of him was a room full of more than 20 skinners!

  Most of these skinners were still wearing thick work clothes and chemical protective suits, which were worn out but not damaged.

  At the same time, the nearly 30 skinners following behind Shen Feng also followed in, attacking from front and back, and surrounded Shen Feng in the middle.

  Fuck!

  Shen Feng cursed inwardly, feeling his liver trembling, picked up the remaining two spray bottles and began to spray boiling water frantically, forming a defensive circle around him, and ran towards a corner of the laboratory.

  This was also his plan B for this trip, the hyperbaric oxygen chamber!

  After seeing Shen Feng appear, the skinners in the laboratory let out a roar and rushed over together, howling wildly and chaotically:

  "Burn... burn him to death!"

  "It hurts... it hurts so much..."

  "Kill... me..."

  "Skin... skin..."

  "Skin... skin..."

  Unlike the skinners outside, with the protection of clothes, these skinners in the laboratory who were wearing clothes were not afraid of the attack of boiling water, and being splashed by some of them made them even crazier!

  The hyperbaric oxygen chamber looked like an egg-shaped iron house, with the door open at this time, and it had been out of operation for who knows how many years.

  Shen Feng threw away the spray bottle in his hand, took out two grenades from his waist, and ran frantically towards the entrance.

  The closest skinner was only two or three meters away from him. He could even feel a few drops of pus being thrown onto his face!

  This narrative has been unlawfully taken from Royal Road. If you see it on Amazon, please report it.

  It's here!

  He opened his mouth, bit the pull rings of the two grenades, pulled them apart, threw them out, and rushed into the hyperbaric oxygen chamber. At the same time, he closed the door and lay on the ground!

  The cabin was immediately dark. He could only hear the skinners outside rushing to the cabin wall and pounding non-stop, trying to rush into the hyperbaric oxygen chamber and tear the only remaining normal human to pieces.

  Shen Feng's heart was beating wildly, holding his head with both hands, waiting for the impact to come.

  Outside the cabin, after a few long seconds, the two grenades exploded at the same time, and thousands of steel balls and countless fragments exploded like a grand death firework, spraying and splashing in all directions!

  Wherever he passed, the flesh and blood bodies had no power to resist at all, and were wantonly torn and cut, and shredded!

  Dozens of skinners didn't even have time to wail before they were beaten into sieves by the dense steel balls!

  The steel balls of the grenade kept bouncing in the sealed laboratory, causing secondary damage.

  In the hyperbaric oxygen chamber, Shen Feng, who was lying on the ground, felt as if a thunderbolt came from the ground, and the deafening sound waves almost made him vomit.

  The sound of the steel balls bouncing disappeared, and Shen Feng slowly got up, his face pale and his whole body trembling.

  Just then, a shadow suddenly pounced in front of him in the darkness, grabbed his neck, opened his bloody mouth and bit towards his face!

  "Bang bang bang!" Shen Feng frantically pulled the trigger of the pistol and hit the attacker.

  The attacker fell to the ground in response. It turned out to be a skinner hiding in the hyperbaric oxygen chamber. At this time, he was dead and couldn't die anymore.

  "Fuck! Fuck! Fuck!" Shen Feng did not stop, and fired all the bullets in the magazine until the sound of the firing pin was constantly heard, and then he stopped.

  "Ugh..." He finally vomited.

  What happened just now has exceeded the limit of ordinary people. Under high-intensity stimulation, the stomach and intestines have a stress response.

  "Pfft!" Spitting out the food residue in his mouth, Shen Feng wiped the corner of his mouth and felt much better.

  I was still too careless.

  I didn't expect that the skinners in the laboratory of the epidemic prevention center were all wearing clothes, and I was almost skinned alive by these monsters.

  Take a deep breath, take the shotgun from behind, and Shen Feng kicked open the door of the hyperbaric oxygen chamber that was deformed by the explosion, and walked out with the gun.

  Outside was a mess of blood and flesh, and all the skinners had been killed by two grenades.

  Shen Feng tried not to look at the terrible corpses. He first rushed to the door and locked the door of the laboratory, and then began to look for the refrigerator in the laboratory.

  The first batch of problematic vaccines was distributed in large quantities at the time, and should be stored in the laboratory refrigerator.

  Sure enough, after opening the refrigerator, test tubes and injections immediately appeared in front of him.

  Due to the explosion just now, many things in it have been shattered, but fortunately there are enough of them.

  Shen Feng quickly found an injection based on the label, which was labeled "Stone Disease Type 1".

  This is it!

  He immediately took out the injection as if he had found a treasure, and took out his mobile phone to open the real doomsday game, saying:

  "The vaccine sample injected by the skinner has been obtained, and apply for the task reward."

  A line of words flashed on the mobile phone screen:

  Please place the vaccine sample in a sealed medical box.

  Sealed medical box?

  Shen Feng looked around and saw a medical box made of stainless steel shell in the corner. The surface was dented by the grenade steel ball, but it was not penetrated.

  He immediately opened the medical box, put the vaccine sample in it, and closed it again.

  Just a few seconds later, a line of words appeared on the phone screen again:

  Rewards have been issued.

  Shen Feng couldn't help but breathe a sigh of relief. Finally, there was no new task this time.

  He immediately opened the medical box and saw that there were still several booklets.

  The game rewards are still so stingy...

  He picked up the first booklet and took a look. His breathing became rapid in an instant:

  "Defender 3 Wheeled Armored Vehicle Operation Manual"

  The second booklet was another document:

  "Qicheng Epidemic Prevention Center's Application for Equipping Wheeled Armored Vehicles for Epidemic Prevention Work"

  The third booklet was a weapon operation manual:

  "Incinerator Weapon Operation Guide (Including Heavy Weapons)"

  The Epidemic Prevention Center actually has wheeled infantry fighting vehicles!

  And there are a lot of heavy weapons!

  It's done, it's done, now I can go to the National Academy of Sciences in the capital!

  Shen Feng immediately took out all three booklets and began to read them carefully.

  The armored vehicle of the Qicheng Epidemic Prevention Center is the Defender 3, which uses honeycomb tires and does not need to be inflated. Even after seven or eight years, there should be no problem.

  The place where the armored vehicles are stored is in the parking lot on the fourth floor underground, and the sealed tanks for storing diesel are also there.

  The armory of the Epidemic Prevention Center is much more abundant than the armory of the Qicheng Police Department. It not only has police firearms such as pistols and submachine guns, but also automatic rifles and grenade launchers. It is simply a small arsenal.

  After quickly reading all three booklets, Shen Feng carefully put them away, picked up the shotgun, and went to the fourth floor underground.

  After the monsters were attracted just now, the skinners in the underground laboratory were basically cleared by him in one wave. The remaining three or two kittens can be dealt with calmly with the shotgun.

  After killing four or five skinners along the way, Shen Feng finally came to the parking lot on the fourth floor underground.

  The sound of footsteps echoed in the parking lot, and the few remaining voice-activated lights suddenly lit up, and a giant beast lying quietly in the dark appeared before his eyes.

  It was the Defender 3 wheeled armored vehicle!
