Before the girl could answer, a familiar voice came from the other side of the wall.

"She didn't hurt her vocal cords in the first place, so she could speak."

The girl was startled, and quickly turned her head to look down, I couldn't see it, I only heard a cold snort (the sound of luck), and immediately, Ling Ge's figure appeared on the wall, sitting side by side with the girl, and his arm gently put on the girl's shoulder.

"You...... Are you a human or a ghost? The girl asked, surprised.

I also want to ask, I have been to the factory on the other side of the wall, and the height difference is the same as that of the community, it is also a high wall of five or six, Ling Ge didn't help running, and jumped up directly? I have seen Ling Gefei on the third floor of a residential building once before, it is very light, but that time, with the help of balconies and railings, I can also go up if I step on it with my hands and feet, but the speed is not as fast as hers, I thought that it was already the limit of Ling Ge's ability, but I didn't expect that she still had a hand.

"Let's go down." Ling Ge smiled indifferently.

The girl didn't dare to do it again, jumped from the wall to my side, rolled forward, got up and stood firm, still the standard parkour move.

After the girl came down, like me, she looked at Ling Ge on the wall in unison, and we both wanted to see how Ling Ge would come down.

Ling Ge also gave me both face, holding the wall with both palms of her hands, and her body swinging forward, just an ordinary free fall, but I noticed that she did two "shrink" movements in the air, and at the same time, her arms were slightly open, like a bird flapping its wings.

After landing on the ground, Ling Ge's knees were slightly bent, and he didn't use the forward roll to roll over the force, and stood firm directly.

"My sister is amazing!" The girl was an expert and could see the way out, so she couldn't help but applaud.

I understand, this is the real "light skill", before Ling Ge officially served as a special attacker, he had practiced retreat for about two years in the deep mountains and old forests in the west, and he may have learned it at that time.

"When did you come here?" I asked, don't keep staring at the girl next to me, anyway, I let her know that this is an island, Ling Ge showed her skills again, she still dares to run?

"It's always been behind the two of you," Ling Ge patted the dust off his hands and turned to the girl, "Is the wound okay?" ”

“…… It's okay, thanks, thanks. ”

"Let's go, go back, take a walk."

“…… Good. ”

The two of them walked side by side in front, I followed behind, Ling Ge still took care of my face, and emphasized with the girl: "If you are shy, you can ignore our boss, others are very easy-going, I won't blame you, you can just ask my sister to say something, but you can't take him seriously, if he hadn't pressed my gun at that time, you and the assault boat would have sunk into the sea together, and he ordered to save you." ”

The girl looked back at me and bowed slightly to me as a sign of gratitude.

Then, the two of them chatted while walking, and under Ling Ge's "coercion and temptation", the girl gradually let go of her restraints and opened the conversation.

She is really surnamed Han, but her name is not Han Xin, but Han Lime, 22 years old, a senior student, and Dongdong is a fellow countryman, a native of Northeast China, with excellent physique since childhood, during the college entrance examination, she chose a normal teacher between the normal and sports schools, majoring in physical education, Han Lime studied very hard, has obtained the qualification of Baoyan, and is ready to stay in school as a physical education teacher after getting a graduate degree.

Parkour is a project that she has been in contact with since the second year of high school, and she has been practicing, because of her skill, she has served as the technical director of a parkour club in Ningbo for a long time during college.

When the zombies broke out, she was lucky that she was not in the school that night (there are so many people in the school, and they are well connected, and there is basically no escape), but she and the club members are borrowing a field to practice parkour in a park, that park is closed at night, there are no tourists, so Han Qingling and a few parkour team members temporarily hid in the park after getting rid of the entanglement of their corpse companions (after becoming zombies, they will not parkour).

But it was a small park, there was no supermarket in it, and there was no provisions, and after two days, they had to leave, looking for various shelters, during which Han Qinglime's companions were killed one after another, or the corpses were transformed, and in the end, only she was left, and she survived until now with her professional parkour skills.

"Ning Pao over there, aren't there any third-order zombies?" I can't help but ask, parkour technology can dodge the primary and second-order zombies, I believe, but the third-order zombie is faster than a horse and the climbing technique is stronger than a cat, how can she hide from it?

"What do you mean by a third-order zombie?" Han Qingling asked.

"It's the kind of zombie with oily skin and four or six arms." I say.

"Oh, you're talking about the mutated monsters, yes, I can't outrun them, but they also have weaknesses."

"Afraid of seawater?" Ling Ge asked, we already know this.

Or is it...... Crystal Blood? I added one more point.

"Sea water? Crystal Blood? Han Qingling frowned and shook his head.

"I don't know about the seawater, but they're not afraid of crystal blood, they just choose to turn a blind eye." Han Qingling corrected, she has been surrounded by zombies for a long time, and she has the right to speak, which we haven't delved into, but we have also found this phenomenon. It may be that the crystal blood contains some kind of illusion that makes the zombie have the illusion of "this is my kind", so it will not take the initiative to attack, because the zombie has a sensitive sense of smell and is very sensitive to the smell of crystal blood.

"And what are they afraid of?" I asked.

"Afraid of metal!"

"Metal?" Ling Ge and I looked at each other, the city was full of metal, and I didn't find that the third-order zombies were afraid of that thing.

Han Qingling took out her dog-legged knife from her belt, pinched the blade, and handed it to Ling Ge: "I don't use this knife to cut zombies, but use it to stick zombies, as long as the blade is attached to the skin of zombies, they will be very afraid, today because I came to chase you, I took off my original armor, otherwise, that armor is also an effective defense against zombies." ”

"What kind of armor?" Ling Ge asked.

"Iron, I found it in a museum, the kind used by medieval Western knights, covered all over the body." Han Qinglime gestured, I have seen it, and I know what the full armor of the West looks like, but that thing is just a thin layer of iron, and even the arrows of the fierce ancient cavalry can't stop it, can it block the claws of the third-order zombies?

When asked her the reason again, Han Qingling couldn't tell her clearly, she just discovered it by accident, after all, she is a sports person like me, not a biochemistry major.

Ling Ge took the dogleg knife, looked at it carefully, scraped the blade with his hand, sniffed it under his nose, and suddenly shouted, "I understand!" It's silver nitrate! ”

"What?" I asked.

"Silver nitrate! The mucous membrane on the surface of the zombie's skin contains silver nitrate! Ling Ge said excitedly.

"How so?"

"It can be inferred from the habits of zombies!" Ling Ge affirmed, "You see, first, zombies are afraid of light, and their vitality is greatly reduced in the sun, while silver nitrate or silver nitrate solution will decompose when it encounters light!" Second, zombies are afraid of seawater, and after being attacked by seawater, there will be a white powdery substance on their bodies, right? ”

I nodded, and it was.

"That's because there is sodium chloride in the seawater, and sodium chloride and silver nitrate will undergo a 'metathesis reaction' to produce silver chloride precipitate, which is the kind of white powder on the skin of zombies! Third, Lime found that zombies are afraid of direct contact with metal on their skin, but they are actually afraid of iron, why? Because iron and silver nitrate will undergo a displacement reaction, replacing the silver inside! Look! ”

The more Ling Ge spoke, the more excited he became, and pointed to the spots on the dogleg knife: "This is the silver that has been replaced-lime, on your armor, where the zombies have touched, is there also this kind of silver spot?" ”

"That's right! That's it! ”

Ling Ge snapped his fingers: "That's easy!" ”

"What's so easy to do?" I asked, confused.

Ling Ge said for a long time, what is silver nitrate?
