"Air transmission?" Liu Yiman couldn't help but frowned: "If it was really air transmission, why are all those here okay?"

"But have you ever thought..." Qin Zijun looked at Liu Yiman: "The zombie virus broke out without warning. In just one or two days, it swept the whole world. More than hundreds of millions of people in our Xia Kingdom were instantly infected, and in a very short time, they immediately turned into zombies!"

After hearing this, Liu Yiman shook his head.

"You still haven't answered my question. If it's really airborne, why are all of us here okay?"

"That's because the zombie virus spreads very quickly at the beginning of its outbreak." Qin Zijun said patiently: "It can spread rapidly at a speed of 1,000 kilometers per hour, and attack those humans suitable for its survival and possession at the first time, forming widespread and large-scale specific transmission~!"

After hearing this, Chen Ping raised his head and asked, "In other words, those of us who survived are not suitable for zombie virus possession and survival?"

"This is just one of the reasons~!" Qin Zijun continued: "There is another important reason, that zombie viruses attack individually. Each zombie virus fails to attack a human and dies immediately, and there will be no second air transmission~!"

"The humans who have been infected with zombie viruses have differentiated their immunity, and their genes mutated in a short time, and eventually became zombie transformed. Whether it is strength, speed is higher than that of ordinary people, and they are manic and cruel, and gradually lose their perception, pain and thoughts. When they see living things, they immediately attack, obtain blood, and nourish the zombie virus in their bodies."

"At the same time, the zombie virus is spread in blood. Once it is attacked by zombies, the infection rate is 100%."

"When the virus in the zombie is nourished by blood and grows to a certain level, it will have a second mutation~!"

"The second mutation?" Lei Ming asked in confusion: "What is the second mutation?"

"The so-called second mutation is to judge from the power and speed of the initial corpse transformation." Qin Zijun continued: "For example, the power and speed of the level 0 zombie we define is equivalent to 0.5 times that of ordinary people. Then after a large amount of blood sucking, the zombie virus in the body grows to a certain level, and its speed and power explode to about 1 times that of ordinary people, which is called a secondary mutation."

"According to my research, the threshold for secondary mutation of zombies is the level 3 zombie we define. It will have jumping attack ability in terms of speed, and its attack power and biting power will reach the level of an adult wild wolf~!"

"Next, in the same way, suck blood, attack living creatures, nourish zombie viruses in the body, reach the level 6 zombie we defined, and a third mutation occurred~!"

Liu Yiman hurriedly asked, "What are the characteristics of the third mutation?"

"The most obvious feature is that we define the level 7 zombie. Its power and speed reach the lioness level and has the ability to perceive~!" Qin Zijun took a deep breath and continued: "Within a certain range, the zombies after three mutated times will sense the existence of the living creature and attack in an accurate direction~!"

"Level 7 zombies are equivalent to lioness level." Chen Ping smiled and looked at everyone: "It seems that we have killed a lot of lioness just now?"

As soon as these words came out, everyone at the scene burst into laughter.

"It should be stronger than the female lion, right?" Chi Lian raised his head and looked at Qin Zijun: "After all, we use ordinary weapons to zombies above level 7 and cannot cause fatal damage to them~!"

Qiu Yongchao looked at Chi Lian: "If you attack the lioness with a gun, you will not be able to lose its combat power without hitting it with just a few shots~!"

"That's right, next, the fourth mutation~!" Qin Zijun glanced at Chen Ping and said in a deep voice: "The so-called fourth mutation is the level 10 zombie we defined."

"Note, this is a watershed and threshold for zombies~!"

"To reach level 10 zombies, according to my calculations, the strength and speed of attacks of at least 500 people is more than 1 times that of adult tigers."

After hearing this, everyone present took a breath of air conditioning.

You know, the attack power of an adult tiger is terrifying and even more terrifying.

A level 10 zombie has reached more than 1 times the attack power of an adult tiger, which is even more creepy.

More importantly, once you are bitten or scratched by these zombies, it will instantly cause zombie virus infection and mutate in a short period of time.

In other words, when faced with these terrifying weird things, no matter if you are a special forces soldier with many battles or a Sanda champion with excellent martial arts, as long as you get caught and bitten by it, you will be completely finished~!

And these zombies are fierce and manic monsters without pain or thought.

Fighting against such an opponent, no matter whether it is level 0, level 3, level 7 or level 10, once it is approached, it will be far from death~!

After pondering for a little while, Chen Ping stared at Qin Zijun: "So, based on your understanding of zombies, what are their weaknesses?"

"I'm studying this~!" Qin Zijun pursed her red lips: "So far, it is basically impossible to remove these zombie viruses on a large scale~!"

"We mainly fight zombies~!" Chi Lian said word by word: "For example, how can we cause a fatal blow when we attack zombies?"

"Head~!" Qin Zijun said confidently: "According to my research, the head of zombie is the base camp of every zombie virus carrier, and it is also the main storage and accumulation point of zombie viruses. As long as the bullet penetrates the head of any zombie, no matter what level it is, it will definitely die~!"

"But I believe that with your experience in fighting zombies, you should probably understand that because the head is the core position of the zombie virus carrier, it is basically difficult to shoot the head with one shot at the speed of zombie viruses, especially at the speed of zombies above level 7~!"

"So, in this case, you will either use rapid-fire weapons with fierce firepower or special weapons with precise sniper rifles~!"

"However, I suggest using rapid-fire weapons with fierce firepower, hoping to raise them a few centimeters, mainly shooting the head of the zombie to ensure a large-scale instant kill~!"

After hearing this, Chen Ping turned his head and looked at the people surrounding him.

"I've heard what Teacher Qin said. If you go on for a while, you must convey it to every combat member~!"

"I understand~!"

Everyone nodded at the same time.

"I have another question~!" Liu Yiman looked up at Qin Zijun: "This time, a large number of zombies gathered on both sides of the southeast of our Yunlin Base are gathered in an organized and obedient manner."

"Don't it be said that zombies have lost their mind, consciousness and perception, why do they obey orders?"
