"What's wrong?" Sun Kai asked curiously.

"Nope. Nothing. I think too much. Ye Wen said.

Well. That's right. I must have thought too much about it. Rebirth has exhausted his character value, how can he still let him run into that legendary character.

"Xiaoyu can use sign language, but none of us know sign language, and we still don't understand what she means." Ye Wen was a little worried.

Xiaoyu said that she had never drawn a road map, and she was afraid that she would not understand it. When we got to the fork in the road, she could tell us how to go on the spot. ”

When Sun Kai's words fell, Ye Wen's eyes changed when he looked at her.

"How do you know sign language?"

"Why can't I know sign language? Didn't I volunteer at a special school this summer? ”

Uh, like, yes, such a thing?

Ye Wen supported his forehead. Oh yes, he remembered. He originally wanted to go with Sun Kai, but the tuition fee was almost not enough, so he used the summer vacation to work. Although Sun Kai's parents put all the tuition fees on his card, after all, it was other people's money, and Ye Wen was really embarrassed to accept it.

Who would have thought that after going around in the last days for ten years, he would have to save for tuition when he came back to this day. He's been on the same page with tuition all his life, right?

Ye Wen felt unprecedented sadness. "Forget it. You'd better draw it. Briefly describe it to us, otherwise I am afraid it will be too late to show us the way. ”

Who knows how many zombies can be on the road. When you are pointing the way, one pops up and is more disturbing.

Sun Kai found pen and paper. The mute girl drew it intently, and then described the road map in sign language, which was translated by Sun Kai. It wasn't until Ye Wen established a clear route in his mind that they ended and went to sleep separately.

The night flies.

At four o'clock in the morning, as agreed, Zhang Heng opened his eyes and walked out of the main building.

Sun Kai had already driven both vehicles to the parking lot, and then went to the commissary to see if there was anything else to take. During this time, Ye Wen looked at the two cars thoughtfully, and seemed to have been standing for a while.

"A few of us, Sun Kai must be in the same car with you, how about I drive the other car?" Zhang Hengmao then recommended himself.

"You're very good at driving?" Ye Wen said, "Today's road will not be too easy. ”

"Of course. I'm driving here. Zhang Heng smiled, "You see that one is mine." It's a pity that it was broken. ”

Following Zhang Heng's fingers, Ye Wen saw the sports car that crashed into the side of the small hotel, and his eyes suddenly froze.

"What's wrong?" Zhang Heng asked strangely.

"It's fine. Sports cars are quite noisy. Not suitable for getting into town. Even if you don't get into an accident, you can just leave it here. Ye Wen said.

"That's right. If it weren't for the noise, it wouldn't attract too many zombies. I just hit the wall to avoid zombies. Zhang Heng said helplessly, "But no matter how good the driving skills are, it is impossible that there will be no movement at all." Let's just enter the city like this, won't we really be surrounded by zombies? ”

"I'm just thinking about it." Ye Wen said, "It is necessary to carry out camouflage. ”

"Smearing the carrion of zombies on the car? It seems that this trick has been used in American dramas. Zhang Heng said jokingly.

"Hmm. Let's get started. ”

"Hey, you're going to do that?!" Zhang Hengfang said, "How stinky is that, the wind can stink for eight hundred miles!" It is said that the sulfur in the gas produced by the decay of the human body can really damage the respiratory tract of people, but it is not as simple as smelling bad. Besides, can this really fool zombies? There is the smell of carrion, and zombies can't smell human flesh? ”

"It may not work in the future. But for now, it should be fine. But the principle is really not the smell. Ye Wen said, "Zhang Heng, have you ever thought about what zombies rely on to identify their prey?" ”

"Voice?"

"Sound can indeed attract the attention of zombies, but people can scream, and zombies will roar. Even if a zombie is feasting on a living person, as soon as that person transforms into a zombie, the other zombies will immediately lose interest in him. Ye Wen said, "Of course, people smell of human flesh, and their body temperature is much higher than that of zombies." But don't zombies that have just been transformed from humans smell like human flesh? There is no body temperature left on the body? ”

"What do you mean......" Zhang Heng thought for a while, "Do zombies rely on the presence or absence of viruses to judge whether they are companions or prey in front of them?" ”

Ye Wen hooked the corners of his mouth. This Zhang Heng is really smart. "So what we have to do is just smear enough virus on the car, not enough stench."

“…… So you're standing here, thinking about where the smell is the weakest after the corpse has decomposed? ”

"It also wants to keep the virus as high as possible." Ye Wen replied very seriously.

The most direct thought must be either brain plasma or blood.

But not to mention, studies in previous lives have found that although the virus content of zombie brain plasma is higher than that of other body parts, it is actually not that high. Zombie viruses do not concentrate in the brain to form crystals or gels, as humans have suspected.

Of course, fly legs are also meat, no more, no more, and you can use your brain. But the brain is also a viscera, that smell...... Well, indescribable.

Even Ye Wen, who was already accustomed to the smell of zombies, didn't want to sit in the encirclement of zombie brains if possible.

Blood can also be, compared to the smell of rotting internal organs that is sour and sweet, and makes people vomit and can eerily stimulate human appetite, bloody gas is definitely pediatric. However, a lot of putrid body fluids seeped into the blood vessels of zombies and mixed with zombie blood, resulting in a very touching smell of blood.

"So what? What's the right thing to use? As soon as Zhang Heng's voice fell, his face suddenly changed, "I'll go...... No way. ”

Ye Wen patted him on the shoulder: "Zhang Heng, you are really smart." The place with the highest concentration of zombie viruses is saliva. ”

Otherwise, why would people get infected as soon as they are bitten?

Of course, there are also scratch infections. But that's mostly because zombies tear off pieces of meat with their hands and stuff them into their mouths, contaminating saliva in the process. With the fierce infectiousness of the zombie virus in the early apocalyptic era, it only takes a very small dose to infect people.

"Saliva is a good thing. The texture is light and thin, and there is basically no need to consider the problem of corruption. Of course, there will be some putrefactive bodily fluids mixed in it, and even that disgusting granular impurity, I don't know where it came from, but probably because zombies need a good set of teeth to eat, their mouths decay very slowly. Overall very suitable. ”

After Ye Wen finished speaking, he patted Zhang Heng's shoulder for the second time, "I think you are very good, I will leave it to you." ”

"No, you, you asked me to scratch the teeth of zombies?!"

From the beginning of this service area, Zhang Heng jumped up for the first time as if literally.

"It's not scraping, we don't need food scraps from zombies. That will also give off a smell. Ye Wen said seriously, "Hurry up." Those zombies have been hanging for more than ten hours, and if they don't hurry up, their saliva will run out. We have two whole cars to wipe, and I can't do it alone.

Or do you want to sit in a zombie brain? Let me remind you, the smell of that thing is similar to that of pigskin jelly that has been on the heating for half a month, and it is only two hundred times stronger. ”
