The airbike traverses the forest quietly, the smooth metal base plate swiping the tip of the grass.

It won't take a few minutes to figure out how this thing drives, but unfortunately now he is a "Ruan Lijie" with mediocre qualifications, so it's not good to overdo it. Ruan Xian sat silently in the back seat, looked up at the sky, and wrapped his arms around Tang Yibu's waist.

Tang Yibu skillfully controlled the floating motorcycle, and the police-type auxiliary machine was firmly behind Ding Zepeng's car.

The Wild Graveyard was northeast of the Refuge, and this time they were heading due north. The forest is getting denser, and more and more sunlight is sifted on the other side of the dense branches. In the gradually thickening shadow, Ruan Xian did not find any trace of human beings except for the rusted metal pylon that had long been abandoned.

"It's here." Lao Zhang stepped off the air motorcycle. "It's not a big job to pick up screws, you don't need to hide the motorcycle, just change the place in time."

Ruan Xian jumped out of the car, the gadgets in his backpack jingled.

His feet stepped on the dense and moist grass, and the air deep in the forest seemed to be soaked in fresh tree sap, fresh and pleasant, full of an inexplicable sense of peace. The age of man is over, but the birds are still chirping above their heads, and the humming of insects is coming from the bushes.

This doesn't look like a place to pick up screws, Ruan Xian thought. This is a better place to find mushrooms than parts.

Zhang Yazhe took out his gun and fiddled with it for a while. Ruan Xian pretended to adjust the hook on his wrist and glanced out of the corner of his eye.

Tang Yibu carried a large bag with more luggage on his back and followed him silently. Chi Lei covered his motorcycle with a camouflage net, and was rolling his cigarette again. Xiao Ding seemed to be the one in the best mood - the young man squatted down and pulled away the grass, a bit like catching a grasshopper.

"I didn't see the scrapped machinery. Brother Zhang, are you sure it's here?" Ruan Xian said politely.

Zhang Yazhe let out a string of pleasant laughter: "Haha Laochi, look, they ask this every time."

Chi Lei snorted from his nose, not intending to pick up the conversation. Zhang Yazhe stuck for a while, then took it by himself: "Xiao Ding, show Xiao Ruan a demonstration."

"Okay!" Ding Zepeng geared up.

He showed Ruan Xian a big smile, stretched out his right arm, and the hook on his right arm shot out a hook. Leaping up the tree by the rope, Ding Zepeng spread out the five fingers of his left hand, with four metal balls firmly sandwiched between the fingers.

"Brother Ruan, look!"

Four metal balls were thrown in different directions one after another, followed by a small gunshot. Putting the gun back into the gun pocket, Ding Zepeng hooked another tree with a hook and sling, and slipped down the rope as nimble as a monkey. After returning to the ground, he touched the target grass and brought a rabbit-sized thing to Ruan Xian.

That thing is a bit like a shrunken police-type machine, and it also has four thin bionic animal feet. However, its structure is simpler, and its body is a bit like a human heart with a metal shell embedded in it. Pale artificial tissue pulsing behind the metal shell, four metal animal feet kicking around.

A pocket metal dart was stuck in the gap of the metal shell, still flashing a little electric light.

"There is a trick to this. Throw the signal shielding balls first, and circle them to ensure that the warning signal will not be transmitted." Ding Zepeng retrieved the metal ball he just dropped and showed it to Ruan Xian carefully. "Novice can use more penalties. I have to use four to be stable. Brother Zhang only needs three to make a return shot. One set for the triangle area is accurate."

"As for the dart gun, Haiming should have matched it for you. Brother Ruan, if you know how to use a gun, it shouldn't be difficult to get started, just shoot them in the cracks of their shells."

"...Why do you say 'picking up screws'?" Ruan Xian looked at the machine that was still struggling.

"It's really picking up screws." Ding Zepeng wiped the sweat from his face and smiled even more happily. He took out a screwdriver from his pocket and pried open the mechanical shell in his hand like an oyster. "There is a very common connection screw in this type of machine. One can be unloaded about ten screws. Hamming likes to use it very much. This thing is not very strong, and it is easy to grasp stupidly."

After the shell was peeled off, the four legs of the machine twitched for a while and stopped moving.

"There is also a bionic machine in this place?" Ruan Xian finally completely took his attention away from Lao Zhang.

"That's right, they all come to eat grass." Ding Zepeng shrugged, "They don't want to burn fuel anymore, they directly imitate the digestive system of herbivores. The shells can be brought back as materials, but unfortunately the meat can't be eaten. Ruan Brother, do you know? This thing can reproduce by itself."

"That's it. Xiao Ruan, if you catch one today, it is considered qualified. Remember to come to my side after you catch it, and I will teach you how to dismantle it." Zhang Yazhe nodded with a smile.

He took the small machine that didn't move from Xiao Ding, and dismantled it completely. The disassembled parts were covered with yellow-white liquid and were thrown into the empty box.

Ruan Xian took a breath from between his teeth. Compared with this thing, the cockroach is more within his psychological tolerance.

But at this point, there was no time for him to digest it slowly. In order to express his "strong desire" to join the team of explorers, Ruan Xian had to follow the instructions and try to capture this kind of thing named "living screw".

Not to mention the psychological obstacles caused by the strange reality, Ruan Xian knew how accurate Tian He's evaluation of himself was when he really moved.

He can indeed hit the gun accurately, but his untrained arms can't support his weight, so he can't easily jump to the top of a tree or swing in the forest with a hook like Ding Zepeng. He can calculate the flight path of each ball, and he knows how to circle the shielding range most efficiently, but he has absolutely no way to control the strength of his arms. The eyes can keep up, the brain can keep up, but the body is panting, and the arms are shaking.

He tossed around here for an hour, and Ding Zepeng had already caught more than 20 live screws there. Tang Yibu leisurely stood beside the folded plastic basket full of live screws, guarded a large pile of packages, and smiled brightly.

Chi Lei dealt with the live screws, cut out the smallest parts, wiped them clean, and put them into small boxes.

"Inhale through your nose and exhale through your mouth, don't exert force when you inhale."

Zhang Yazhe threw a bunch of live screws with outstretched legs into a plastic basket, wiped his hands on his clothes, approached Ruan Xian, and patted his sweat-soaked back lightly.

"The center of gravity is lowered again, and the body is leaning forward. You have a good foundation, but you are breathing too much, and it is easy to suffocate your breath when you exert your strength."

"Thank you Brother Zhang." Ruan Xian shrank his body calmly and consciously controlled his breathing.

"Take a break, it's almost time. Drink some water and eat something, we'll change places later... Xiao Ding, Xiao Ding! Stop catching, come back and rest!" Zhang Yazhe almost shouted in the second half of his sentence. Ding Zepeng caught up and ran farther and farther, almost disappearing from their sight.

Ruan Xian lowered his head and returned to the package, took two sips of water, and began to read the e-paper obtained from Guan Haiming.

Five minutes later, Ding Zepeng finally returned to the main force. The young man's face was covered with thick dust, and his whole body was dirty. He hummed an unknown tune and threw two or three live screws into the plastic basket.

"Wipe your face!" Zhang Yazhe twisted a warm towel and handed it over. "You can see that Xiao Ruan is more honest, and he likes all the books."

"I don't like studying." Xiao Ding wiped his face with a towel, took out a glass of water and took a few gulps. "Brother Ruan, what are you looking at?"

"Introduction to Auxiliary Machinery, I asked for it from Guan Bo." Ruan Xian shook the electronic paper in his hand.

"It's useless, it's all empty talk." Chi Lei wiped his hands carefully and interjected coldly. Zhang Yazhe gave him a disapproving look.

"I just want to understand first, it's too complicated to understand." Ruan Xian didn't mean to be angry, and his tone was very soft.

"Don't listen to Lao Chi's nonsense, "Introduction to Auxiliary Machinery" was compiled by himself, and he is unwilling to sign it." Zhang Yazhe pressed his elbow against Chi Lei with a cold face, "it suits your situation, just look at it. Ruan, I have some vitamin C tablets, do you want to soak it in water?"

"No need, Brother Zhang."

"Is there anything you don't understand?"

"It's nothing, I'm still looking at the initial part. Guan Bo said that the main brain can't restore the A-type and S-type, but he didn't go into details. I'm still a little worried. Do you know anything about this?" Ruan Xian rubbed the electronic device with his hand. The words on the paper stared at Zhang Yazhe without blinking.

"Hey, what do I think you are afraid of!"

Lao Zhang poured the warm water from the water bottle into the cup and smiled until his eyes narrowed.

"You should know the relationship between AI and the initial aircraft, right? The initial aircraft is a type of airframe. If the airframe is compared to an airplane, the AI ​​carried is the pilot inside. Without AI control, the airframe itself is a non-moving shell. Son, there is nothing to worry about."

He took a bite of the potato cake and pointed to Tang Yibu, who was sitting a few steps away: "Of course, planes can fly without a pilot. But what they can do is very limited, such as 231, which is not motivated by "self-experience" "The judgment mechanism cannot deal with complex situations, and can only execute the set instructions."

"Str-y type 307a231 is at your service." Tang Yibu turned his head and responded with a smile.

"look."

"I understand this. But since the master has forced people to do this, maybe he can break through Ruan Xian's technology..."

Chi Lei's face, who was silent, turned black instantly.

"Bah, pah, you can't talk nonsense!" Seeing Chi Lei's forehead jumping out of the blue veins, Old Zhang Chong Ruan Xian vigorously waved his hand. "You have to call Ruan Bo or Professor Ruan!"

Ruan Xian pursed his lips.

"In short, Xiao Ruan, don't worry, the A-type and S-type are really destroyed, and the mul-01 will never be reproduced. Alas, it is fortunate that those two were destroyed. We have encountered a pre-apocalyptic A-type product before. , that's tough. Let's put it this way, if the live screw is a type A product, one can beat the four of us back."

"What about the S type?" Ruan Xian glanced at Tang Yibu and continued to ask in a very natural tone.

"If there are so many S-type products, everyone should not leave the shelter. If we leave the hidden range of perception camouflage, we will be discovered in an instant. And it is said that S-type products can repair other types of airframes, which is very tricky."

Zhang Yazhe stuffed the potato cake into his mouth and shook his head. "D-type products can be dealt with if you find the right tricks, fortunately."

"231 is also a d-type product?"

"It? When it was produced, it didn't have Professor Ruan's initial machine, and it was not a model of any kind." It was Chi Lei who answered this time. Zhang Yazhe glanced at Tang Yibu, his expression dimmed for a moment.

Ruan Xian didn't let go of the other party's expression.

"Continue to talk about the initial machine, let me explain to Xiao Ruan, otherwise, young people will be afraid of this all day long." Zhang Yazhe brought the topic back directly.

He poured two glasses of warm water in front of him.

"Professor Ruan anticipated possible accidents back then." Zhang Yazhe's expression became serious, he took out a little butter from his pocket and threw it into the water glass. Butter floats on the water. "Under normal circumstances, the initial machine can be accepted and processed by various artificial cells without being affected. If I smash this cup, I can still get clean water."

Then he took out another yellow tablet and threw it into another glass of water. The water is dyed a cheerful orange yellow as the gurgling foam dissipates, with a hint of orange aroma.

"If human cells are encountered, they will be marked and changed by human cells. Although their own capabilities are still there, they can no longer be fully utilized by other organisms - as long as the initial machine is poured into human tissue, even mul-01 will not be able to Restore them back. Well, if I smash this glass now, I can only get orange juice... Xiao Ruan, do you really want a glass?"

Ruan Xian shook his head and raised his half-full water glass.

"Orange juice will also contain water after distilling it." Chi Lei added quietly.

"What are you doing!" Zhang Yazhe laughed and scolded, "Let the young people relax for a while, okay?"

"Brother Ruan thinks too much." Ding Zepeng took the potato cake in his mouth and grabbed the orange juice that Lao Zhang had soaked in his hand, his tone was quite emotional. "I never thought about other initial machines. I was even more afraid that the cockroach would eat the earth."

Turning to Ding Zepeng, Chi Lei's expression softened a little, and even the corners of his mouth curved.

"Are you still worried?" Lao Zhang asked with a smile.

"Don't worry." Ruan Xian put away the electronic paper neatly, "Thank you Brother Zhang for your explanation."

He swept in Tang Yibu's direction again, but this time their eyes just collided.

The bright fake smile on Tang Yibu's face disappeared, and his expression became blank. But before Ruan Xian stood up, Tang Yibu raised a hand and pointed to his ear.

Ruan Xian didn't stand still for too long.

He put down the potato cake in his hand and held his breath. Filtering out the laughter of Zhang Yazhe and Ding Zepeng in front of him, the unpleasant trampling sound came from afar. The sound was different from that of the cockroach. This time, there was some kind of larger creature - or machine - approaching in this direction.

"Are we going to change the place to grab the live screws?" Ruan Xian quickly stood up.

"Little Ruan?"

"Everyone has finished eating, hasn't it? Don't worry about me, I'm already resting. If you want to change place-"

At the same time, the police auxiliary machine, which had been wandering on the grass, let out a harsh shriek.

"...It's not that I don't care about your problem, no one can leave now." Calling the auxiliary machine over and taking a look, Lao Chi snuffed out the cigarette butt he was holding, and his voice changed a bit.

"We were discovered by two large machines."

Zhang Yazhe was stunned, and Ruan Xian's heart sank - this should not be part of the so-called "resignation plan", Zhang Yazhe's surprise was not adulterated.

"231 to set up the confusion net. The police type go to explore and get some information back. Sacrifice a floating motorcycle, let it drive away automatically, and draw their attention." Zhang Yazhe ordered in a deep voice."Everyone is on the tree. Xiao Ding, bring some Xiao Ruan."

"Yes!" Xiao Ding immediately accepted the smile.

"Xiao Ruan, take your gun. Don't move without orders, don't take it lightly."

Zhang Yazhe frowned, his hands turned out two guns like magic, and his tone was very serious.

"...that's the threat you should really be worried about."
