"It's the silk of the plain, which refers to the scroll. It's not the Hunan of Xiaoxiang. ”

Li Yan corrected, he was used to the reaction of others when they heard his name for the first time, and there was no way to call that Li Xiang too famous before the end of the world, especially in the territory of Tanzhou.

"Fortunately, fortunately."

Zhao Xinghua saw that the inspection had been completed, sat up and put on the snake molt armor, and said in his mouth.

"You said you came from Suishi, what's the situation outside?"

"Natural disasters have changed the ecology of the world, both good and bad, it is a catastrophe for human beings, but it is an opportunity for other organisms to evolve and improve."

"If it's okay, come and sit with me in a while, I still have a few bottles here to collect Feitian Moutai, you can talk while talking."

"Is it collected? Or is it the benefit of taking the patient? ”

"Hehe, it's no difference, I don't have a salary now, and I should collect some thanks, right?"

"Since it's a bribe, how can I cheapen you, I want to confiscate it on behalf of the masses. Wait a minute, I'll call my friend to come along. ”

In an apartment on the tenth floor of the north tower of Tanzhou Wanjia International Center, Zhao Xinghua, Liang Hanba, and Li Yan sat on the carpet, with two wine bottles in front of them, all of whom were slightly drunk.

"Well, this place is really one of the few safe areas, and there has never been a place in the city that can build such a large survival shelter except for a base surrounded by water like Fengchong Airport."

"Tanzhou has been a battleground for soldiers since ancient times, there were many troops here before the end of the world, and it is also the capital of Xiaoxiang Province, in addition to this large fortress, there is also a refuge on the Orange Island in Tanzhou, where more than 20,000 survivors live."

"Doctor Li, do you say that this sonic zombie is a little invincible? As you said before, infrasound waves are defenseless, they can diffract around obstacles like electromagnetic waves, armor and buildings cannot isolate this damage, and the only way to do this is to snipe from a distance. There are thousands of such zombies in the city, if they are allowed to evolve, then this survival point is not very safe, and the building can't resist the transmission of sound waves? ”

"The experts in the base have also specially studied the characteristics of this kind of zombie, and have done various experiments, high-level sonic zombies can hurt creatures dozens of meters away, according to the physical characteristics of infrasound, it is not a problem to transmit a distance of thousands or even tens of thousands of meters, and it can even be farther than the distance of a sniper rifle. According to the principles of physics, the lower the frequency of a sound wave, the less it is absorbed by the medium and the farther the wave travels. For example, the audible sound waves produced by artillery shells cannot be heard at a distance of several kilometers due to their rapid attenuation, but the infrasound waves generated by them can be transmitted up to 80 kilometers away; The infrasound waves produced by the hydrogen bomb can travel several times around the earth and travel more than 100,000 kilometers. Fortunately, the energy in the zombie corpse is not so exaggerated, and most sonic zombies only use this ability when their lives are threatened, because each time they use it, it also has a lot of damage to itself, just like the bee sting and the Seven Wounds Punch in the novel, it has irreversible damage to itself. With each activation, the longer the energy needs to be accumulated. According to the number of sonic waves that sonic zombies can launch during an attack, we divide them into one shouting zombie, two shouting zombies, three shouting zombies, and so on, and the highest level known so far is three shouting zombies. ”

"Lao Liang, listen, they call this kind of zombie 'shout'. Hahaha, it is worthy of a city with a happy base camp, and never forget entertainment. ”

Liang Hanba has always looked preoccupied in the past two days, Zhao Xinghua didn't know what he was thinking, and at first he thought he was worried about his injury, but then the two came to this base, Liang Hanba still often chattered alone every day, Zhao Xinghua deliberately messed with his thinking at this time, wanting him to return to his original appearance.

Liang Hanba picked up the wine glass and took another sip, and asked Li Yan:

"Doctor Li, do you say that there are other creatures besides this zombie that can produce infrasound?"

"Yes, the elephant before the end of the day stomping on the ground emits infrasound waves, and the same kind can be felt by the feet of the same kind in the distance. Crocodiles, during courtship, will vibrate their backs on the surface of the water to emit infrasound waves, which can be felt by the opposite sex at a distance. Tiger, tiger roar has the power of infrasound, can shock the joints of people's ears that are misaligned, and the sound can travel far from low to high. But this is only an infrasound wave in frequency, and some very large animals can emit very low bass, and even infrasound, but they are also used to transmit information, and they are still too low to use for damage. Because the infrasonic attenuation is very fast, it is necessary to strengthen the localization of the injury, in addition to having a strong vocal organ, there must also be a gathering organ, because the direction of the low frequency is very poor, which requires a strong ability reserve. ”

After listening to Li Yan's story, Liang Hanba pondered for a while, then took out a booklet from his bosom that he had taken from Huang Tingguan and said:

"This is an overview of Taoist talismans, I have been studying Taoist talismans a few days ago, and I also want to make some talismans like Daoist Guang Zhenzi, but I can't always get started, I feel that this thing is too mysterious, after the Zhao team was injured by zombies that day, I took a look at the part about Taoist spells, and I wondered, whether these spells are also related to sound waves."

Li Yan reached out and took the ancient book "Tao Jing" that was stamped from right to left, flipped it over, looked at it twice, and then looked at the two of them in confusion, with a very puzzled expression.

"Does this have anything to do with sonic zombies?"

"No, I first studied the production of the talisman for a few days, and the Taoists said that it was necessary to use the True Yuan Dao method to transform the power of the talisman. The so-called Taoist True Yuan should be the acquired energy that cultivators possess that is stronger than that of ordinary humans, which is equivalent to the superpowers that we post-apocalyptic evolutionaries have. If we use other ways as a source of energy to drive these paths, we may be able to reap the rewards as well. ”

"Mr. Liang, I still don't understand."

Li Yan, a young medical doctor, studied modern science, did not understand Taoism and supernatural powers, and did not accept these theories very much in his heart.

"I studied the talisman for some days and felt that I couldn't start, even if it was the exact same that could be copied, it was impossible to achieve that effect, yellow paper is still yellow paper, but there are more symbols drawn on it by cinnabar. After we encountered the sonic zombie in the supermarket, I thought we could try it from the "Taoist Proverbs" or the "Buddhist Lion's Roar", since zombies can have infrasonic attacks, maybe the Proverbs spell can really subdue demons and subdue demons to cause damage to the enemy? ”

Liang Hanba said the questions he had been thinking about in the past few days.

"I don't understand what you're talking about, but I do know one that touches on that."

Li Yan knew that these two people were human beings with high-level evolution abilities, and he had just heard about the achievements of the two while drinking and bragging, and some of the stories might be exaggerated, but most of them were still convinced. You know, if you don't see it with your own eyes, it is difficult for ordinary people to imagine the endless scene of giant rats galloping at the same time, and a big bird with wings more than ten meters long will be tamed by humans? Aren't Gu worms all the content of movies and novels? Is there anyone else who can use a piece of yellow paper to make a zombie inactive? He also has incredible abilities after the natural disaster, which conflict with the knowledge system he has accepted, but people can become zombies, and this damn apocalypse is not reliable and scientific.
