Three days later, somewhere in District 3 of Shashi, Yang Bensheng and Lin Wenjin were walking cautiously in the alley, followed by Lao Zhao.

In the afternoon, the city was still deadly silent, and only the occasional sound of a black corpse could be heard.

The three of them lined up and walked slowly between various obstacles, trying to avoid making noise by touching cans and other objects. Lin Wenjin walked in the front with a pulley tiger crossbow, Yang Bensheng in the center, and Lao Zhao in the last with a gun.

Although the three of them were all capable people, in the urban area full of black corpses, there were three first-order early stage capable people...... It's really not enough to see. Although Chen Xinyan has the ability to detect and investigate, the fewer people in the search team, the safer it is. Now that the three of them are blind, they can only be careful with all their might, and then pray for good luck.

At the end of the alley is a clinic, with "Puren Clinic" and "Injection, Infusion" posted on the wall, which belong to the kind that cannot be found without looking at the map.

"Click."

The sharp crossbow bolt shot into the brain nucleus of a black corpse against the wall, ending the second half of its decaying life.

Although Lin Wenjin didn't know what it was meditating on the wall with one hand, it didn't stop Lin Wenjin's determination to kill it in the slightest.

He then closed his fingers, stretched out his arms and swung horizontally behind him, making a tactical gesture of "forward" to the two behind him, and then took the lead in breaking into the clinic.

……

Three days ago, Taifeng gas station in the southwest suburbs of Shashi.

The group hurriedly broke into the convenience store, kicked open the door of the nearby staff lounge, and placed the young man on the bed.

"Haiping, Lan Xi, go guard the door!" Yang Bensheng hurriedly ordered, turned his head and looked at his wife again, "Sister Ping, how is Xiaohua?" ”

"Ping's mother, save him quickly. Brother Lang Hua has been bleeding. Yang Xiaoxiao was already so anxious that she was about to cry.

Li Liping was obviously also flustered: "I...... It seems to be worse than the coma two years ago. ”

"Let me see", Chen Xinyan squeezed through the crowd and came to the bedside at this time.

"Doctor Chen, help me, my brother's forehead is so hot." , Lin Qian stumbled, tears kept rolling in her eyes, "He...... How he didn't have a pulse anymore. ”

"Don't panic", Chen Xinyan stretched her brows and let go of Lang Hua's wrist, "The pulse is weak and the frequency is increasing, it's shock." ”

"Lang...... Lang Hua, is he going to be a corpse? Suddenly there was an exclamation from the crowd, "He has corpse spots on his legs." ”

The others looked in the direction of his fingers, and sure enough, they saw that the skin on Lang Hua's exposed calves was pale and even purple, and was undergoing patchy changes.

"Look, look! What the hell, I don't want to be with the black corpse. ”

People were talking, and they retreated a lot in an instant, and distanced themselves from Lang Hua on the bed.

"Nonsense!" Yang Xiaoxiao pulled out the dagger with a "pout", gritted his teeth viciously and said, "Who dares to talk nonsense, see if I don't cut his tongue!" ”

Although people were afraid of her, there were also people who protested with their necks stalked.

"Look at him for yourself, everyone can see it."

That is, the post-cataclysmic world cannot be judged by common sense. Maybe he's a black corpse now. ”

"You guys!" Yang Xiaoxiao was about to have a seizure, but at this time, Chen Xinyan turned her head and glared at them coldly.

"A bunch of idiots." She opened Lang Hua's eyelids to check the pupils, and added, "The skin is clammy and cold, spots appear, blood pressure drops, loss of consciousness, and the pulse is fast, which is clearly the main clinical manifestation of shock." It's so rare and weird! ”

Chen Xinyan usually looks elegant and gentle, but now she suddenly scolded coldly, which scared everyone.

As the most calm and composed person present, Yang Xiaoxiao was close to her white coat, feeling unprecedentedly reliable and reassured.

Zhou Jin came out to play a round at this time: "It's not good if there are too many people staying here, I will take people to check the surrounding environment to avoid hidden black corpses from harming people." That's the first thing to do. ”

"Okay, then it's up to Dr. Zhou." Yang Bensheng nodded in thanks.

"Forget it", Lin Qian comforted Yang Xiaoxiao after they left, "Leaving them here is also adding to the chaos, it's better to get away and save yourself from looking upset." ”

"Doctor Chen, how is Xiaohua?" After all the irrelevant people left, Yang Bensheng no longer hid the anxious look on his face.

"It's not going well." Chen Xinyan shook her head, "Lang Hua is mostly septic shock this time, which is sepsis syndrome with shock caused by microorganisms and their toxins. ”

Lin Wenjin was worried: "Toxin, is it ......?"

Chen Xinyan seemed to know what he wanted to say: "It shouldn't be spore corpse poison." I wasn't lying when everyone was there. Lang Hua is indeed just in shock this time, and it has nothing to do with corpse poison and corpse transformation. ”

However, the microorganisms in the foci of infection, their toxins, and cell wall products have invaded Langhua's blood circulation, activating various cells and humoral systems of the host. The subsequent cytokines and endogenous mediators will act on various organs and systems of the body, affecting blood perfusion, leading to ischemia and hypoxia of histiocytes, metabolic disorders and dysfunction, and in severe cases, even multi-organ failure. ”

"Is it so serious?" Lin Qian couldn't believe it, obviously Lang Hua was still alive before.

She couldn't help but think of a possibility - could it be that Lang Hua's strange coma two years ago has not recovered until now? Nosebleeds, high fever, sudden coma, are these identical symptoms all a coincidence?

She looked at Li Liping and found that the other party was also thinking, probably thinking of the same thing.

"Heart...... Sister Chen, could you be mistaken? My brother has always been healthy and strong. Yang Xiaoxiao's eyes widened in disbelief.

She didn't know about the accident when Lang Hua first came to Yang's house. In her eyes, Lang Hua has always been the most powerful, the bravest, and the omnipotent figure no matter when and where. It's like she was in the dark street after "Advent Day", but she also firmly believed that Brother Lang Hua would definitely come to save her. Even if the sky falls, there will be a taller brother Lang Hua to support him and not be able to fall.

Lin Wenjin opened his mouth to say something. In his past experience, young and capable people like Chen Xinyan are the most arrogant. Although she is usually silent, looks gentle and lovely, and harmless to humans and animals, if it comes to the field she is best at, she will immediately become a temper.

Lang Hua's symptoms are beyond the scope of Li Liping's ability to deal with, Zhou Jin's attitude is unclear, and now the only person they can trust is Chen Xinyan. Although Lang Hua gave the medicine first, how can it be clear which is more important than Lang Hua's life.

"I'm sorry too, but pathology is my specialty, so please trust my judgment."

Chen Xinyan was not angry because of Yang Xiaoxiao's questioning, she touched Xiaoxiao's head and explained:

That's what the symptoms are all about. As for the cause, it's hard for me to say. It may be that the pathogenic bacteria that mutated after the catastrophe came into contact with Lang Hua and brought about the infection. It is also possible that Lang Hua originally had some kind of chronic underlying disease, and was exposed to bacterial toxins in the ice and snow environment, which caused toxic shock syndrome. ”

"That'...... So how are we okay? Yang Xiaoxiao said in despair.

"Truth be told, the post-cataclysmic world is beyond my capabilities. Now Lang Hua's severe illness is the result of the interaction between microbial factors and the body's defense mechanisms. The number of microorganisms may not be strong, but Lang Hua's internal environment is very bad. ”

"Pale skin, clammy extremities, and cyanosis with patchy contractions are mainly due to hypoperfusion of the microcirculation after a drop in blood pressure. Although the blood loss has stopped, he continues to have a high fever in his head and neck, and fundus examination can show arteriolar spasm and venous stasis, indicating that he has developed symptoms of increased intracranial pressure. If the fever does not subside quickly, his life will be in danger. ”

"I ...... Will my ability 'Ice Clear Lotus' help? Li Liping finally remembered her identity as an capable person.

That's right, since Bing Qinglian can heal the burns on Wang Ming's face, who said that there won't be a miracle effect on Lang Hua?

"It should be possible," Chen Xinyan nodded, "However, before the pathogenic bacteria are identified, I can only speculate on the most likely pathogenic bacteria based on the primary lesion and clinical manifestations, and choose a strong fungicide with a wide antibacterial spectrum for treatment." ”

Yang Bensheng immediately said: "I understand, I'll go to the city to get the medicine now." ”

Lin Wenjin stood up: "I'll go too, my lover was also a doctor, and I also know a little bit about it." ”

"I also need equipment for infusion expansion and maintenance of organ function, and Dr. Li Liping stayed behind to help me stabilize Langhua's condition."

……

"Da-da-da-da."

In the fierce firing, Lin Wenjin had no time to recall what happened three days ago.

Who would have thought that this clinic would be a gathering place for the corpses of the "Screamers"!

The "Screaming Black Corpse", which can emit a high-decibel piercing scream, gathers many black corpses through the noise, forming a small group of corpses around it.

I knew that this situation would be encountered, no matter whether those people in the Qin family were willing or not, Lin Wenjin said that he would drag a Xia Qing to get the medicine together.

No, if he had known that he would meet the "Screamer", Lin Wenjin would not have come here at all. Although it is the closest, it is not without other options.

In fact, that's what he intended. After discovering the corpses of the "Screamers" in the Puren Clinic, they were supposed to retreat and leave quietly. But who knew that Lao Zhao, a messy thing, happened to step on a mineral water bottle at this time. Fortunately, the attention of the corpses was completely attracted, and they couldn't run if they wanted to!

"Damn Lao Zhao! See how I go out and settle this account with you. Lin Wenjin scolded angrily, and hurriedly shot a limited number of crossbow arrows at the black corpse.

"I don't want to, how can you blame me completely. After all, it's not your fault for leading the way here! ”

"Stop arguing." Yang Bensheng made the water knife cut into the neck of a black corpse, and the water shield appeared on his side to block the sharp claws of the other black corpse, and said in a deep voice, "Find a chance to break through!" ”

A corpse claw slashed on Lin Wenjin's shoulder, and a hole appeared in the thick canvas coat in a blink of an eye.

He hurriedly said: "The surname is Zhao, can you stop shooting again?" Is your ability to evolve an ornament? The black corpses three streets away are going to be lured by you! ”

"What can I do? The muffler was scrapped by these guys with a single paw. ”

"Forget it, we've already attracted enough black corpses anyway." Li Wenjin tried to get close to the "J-shaped scream" again and again, but he never succeeded.

"Damn, it's coming again!" He saw that the "J-shaped scream" opened its mouth wide, and the corners of its mouth almost reached the root of his ears, so he hurriedly shouted, "Brother Sheng! Turn on the water curtain quickly. The brute is shouting again! ”

In the next moment, a hemispherical liquid barrier with water ripples formed out of thin air, enveloping the three of them.

They had covered their ears tightly, but the shrill scream still hit the eardrums, giving people a splitting headache.

Prior to this, they had already suffered three attacks from the "J-Scream".

According to Lang Hua's previous statement, this special black corpse is called "Screamer", and the chance of being generated in the corpse group is less than 1%. When encountering human evolutionaries, they are capable of attacking with high-frequency screams. Although this scream is not fatal, during the Screamer's activity, there will always be many other types of black corpses that gather around it due to the noise attraction, forming a group of corpses.

High-frequency screams occur every once in a while, directly interfering with the evolutionary's process of clearing the corpses. If it weren't for Yang Bensheng's skill "Water Curtain" that could block sound waves to a certain extent, they would have been torn apart by the black corpse that pounced on them!

Sonic attacks have a long history of human warfare. More than 300 years ago, during World War II, the Nazis installed a psychological warfare device similar to an "air alarm" on the Ju-87 "Stuka" dive bomber. When the bomber accelerates during a steep dive bombing attack, and the air hits at a sufficient speed, it emits a distinctive howling sound that causes great panic among the Allied soldiers and civilians.

Later declassified documents from the CIA also revealed that its spy group had tried to replicate the model in the 1950s out of war intimidation, hoping to make a device that could emit a terrible and painful sound and install it on an airplane. When the aircraft passes at a low altitude over enemy positions or civilian areas, flying at a speed of more than 300 mph and only a few hundred feet above the ground, the screaming sound hits the human eardrum, causing extremely strong discomfort, similar to the "J-screech" attack.

"Damn, if you don't kill it, no one will want to leave today!"

Yang Bensheng roared, let go of the hands covering his ears, and output the water system energy with all his strength, slowly advancing forward while supporting the defense of the water film.

This tactic was negotiated on the first two occasions. The Water Curtain Defense gives them a short respite. After getting close to the target, Yang Bensheng used a water net to bind the "J-shaped scream", and finally waited for Lao Zhao to use the strengthened "iron fist" to kill the screamer.

The high-frequency screams last only a few seconds, so the best time to attack is when the screams stop!

"There's a play." Yang Bensheng's eyes lit up, and he felt that he could succeed this time.

But at this time, Lao Zhao smiled and punched Yang Bensheng's back of the head.

"Die!"

"Be careful!"

Lin Wenjin, who was defended by two people, discovered this scene through the afterglow. But at this time, he didn't have time to do anything except be able to say these two words.
