On the roof of a ruined pre-war skyscraper in the middle of the Dog City, a giant signal transmitter and receiver that has been restored with various recovered parts is ready to send signals in all directions, and these signals will reach as far west as possible, even to the city built on top of a great old world building that Andy has always heard of but never visited.

None of the salvage crews believed that this eerie postmodern metal artwork resembled a savage metal tree, but that idea changed when a ghoul in a bomber jacket and goggles arrived in Dogtown from the south and joined with his mechanical skills.

Over the course of two years, Wagner made it clear that others were asking for a large number of special components that were difficult to find and almost impossible to discern what they were for.

So, at first, the salvages showed little enthusiasm, and Wagner's list was progressing rather slowly.

It wasn't until he built a small receiver that allowed the salvagers to hear some of the weird wasteland radio stations around it.

This small device is a testament to Wagner's technical prowess, and at the same time makes it clear what he is trying to make.

The entertainment in Dog City was so barren that a concerted effort was made to search for the parts Wagner needed, and two years later, a large, bizarrely shaped signal device was built, using the remains of equipment from the roof of the Salvator's new camp building and a large number of recovered parts.

This was a feat that established Wagner's position in the small group, and the salvage crews of Dogtown not only used the device for entertainment, but also used it to connect with Eddie's car radio, allowing Dogtown to get the only trade route before Andy's arrival.

Today, Andy and Wagner met again on the top floor of the Salvage Camp building, which had an extremely open view, but was limited by the red sand and dust, and could not see far with the naked eye.

There were a large number of metal parts and electronic devices piled up around, some of which had been dismantled and some were rusted and thrown in the corners.

A small shack was not far away, it was a metal shack, welded with a combination of scrapped car shells and staircase metal wreckage, which did not seem very suitable to live in, and the whole shack was filthy and full of red condensation stains.

This small abode belongs to the ghoul Wagner, the only member of the Dog City Salvage Crews. At the moment he was using several tools to maintain the sculpture-like transmitter of the artwork, and no one but himself could really understand the structure of the thing.

The leather bomber jacket was mottled and the goggles were cracked, but Wagner didn't think it was right and kept the look.

From the back, he barely shows any difference from a normal human, but once you turn your attention to the back of his hand, the appearance of skin is quite terrifying, and the withered muscles and blood vessels are directly exposed to the air, taking on a sickly red color.

In some places, white bones were exposed....... At the end of the fingers, there were dirty yellow nails that were slightly curled, embedded in black-red mud, probably a mixture of motor oil and red dust.

"It's a magical state!" The electronic eyes of the cylinder brain kept watching, and he couldn't understand why this miserable-looking guy in front of him was still alive.

"He's so filthy and tattered, like a carrion dug up from a grave, I wouldn't be surprised if any parts of his body fell off, what is the principle that keeps him from dying of diseases caused by infection?" Andy watched Wagner squatting there busy repairing and motionless, and it was estimated that he couldn't hear a few people chatting at this distance, after all, this guy even had his ears gone, leaving only two holes and a faint outline of his outer ears.

"I don't know why, but everyone in the wasteland knows that ghouls are like ghosts that have escaped from hell, they are like they have escaped from death.... I've heard that ghouls don't even need to see a doctor, they don't even eat or drink, but they don't see a significant reduction in mobility. "The strings do understand something.

"I once watched an autopsy where one of my teachers used a ghoul killed by a soldier to teach biology... Not a guy in his right mind, of course, but a complete beast. We see ghouls in their bodies filled with super-high doses of radioactivity, which could theoretically be easily fatal, but for them seem to have the opposite function... One speculation is that they use radiation to form a circulatory system that is different from our common biological tissues. Tankbrain shook his head in discomprehension.

"Radiation destroys dNA and makes people fall apart after metabolism, how can it be possible to sustain life in reverse, are you sure it's true? It's crazy, isn't it..."

"That's really where the problem is." The eyes under the string gas mask looked at the ghoul.

"In most cases, ingestion of excess radiation will inevitably end life... But some of these cases are not, no one knows exactly why, some people say that it is probably due to genetic differences, but why do some people in humans have this recessive gene that can be activated by radiation? In the observations conducted in our lab, all of the ghouls have undergone homogeneous mutations in their genes, making them appear to be aliens. Their body temperature is quite low, and their organs are very sluggish, but you can see the wild ghouls on the road, they are not slow-moving, cold-blooded animals. With that, Wagner seemed to have completed his maintenance task, got up from the ground, and put the tools in his hand into the toolbox.

He turned, and through the large, brown cracked goggles, Andy and the three of them saw the terrifying face below, as if some reddish-brown flesh had been wrapped around the skull, and the tissues were a little twisted in some places.

If you encounter this face at night, no one dares to say that you have the leisure to tell whether the other party is crazy or not.

"Oh, long time no see, Andy... Those new friends of yours don't look easy. Dressed in a tattered bomber jacket, Wagner greeted in a hoarse voice, and his two eyes, which were large because of the lack of eyelids, examined the people who came to him without a trace.

"Except for the indispensable beauties... What's going on with this tin can? Did you reprogram it? An antique robot found in some tattered pre-war ruins? Hearing this, the tank brain was a little angry.

"You rotting piece of meat! I'm not a robot, you should take a good look at my head with your deflated ball-like eyes! I am human! Wagner grinned and sneered.

"So.... Your definition of a human being seems a bit simplistic, is a hapless guy who was blown up by a bomb and only had one organ left human? I don't think you're a human, you're just a machine-man with a core processor that will one day rot and stink. The tank brain was even more annoyed.

"If I'm not human, then neither are you! You disfigured monster should lie in a coffin and settle in the ground, my olfactory sensors can smell you from so far away, look at your bare bones and filthy flesh, and the wriggling maggots in the sewers are more beautiful than you! Wagner's toolbox fell to the ground, his fists clenched, and his cloudy eyes seemed to be on fire.

Seeing that things were on the verge of getting out of control, Andy hurriedly stepped forward to mediate. After threatening to keep his mouth shut, he tried his best to reassure Wagner not to be like this tin can.

Wagner seemed genuinely annoyed, but reluctantly stopped focusing on it, and he and Andy discussed the use of signalling devices to advertise tonic creams.

In the end, the two men agreed to wait for Wagner to completely adjust the equipment before starting to do it in earnest the next day.

On the way out of the roof, Xian turned his head to look at the ghoul behind him, he stood there in silence and watched Andy and the others leave, and after noticing Xian's gaze, he smiled faintly, and crouched under the signal device again.

"Damn slippery skin and stupid brains...", Wagner muttered, and a prompt popped up from the display terminal next to him, as if an unknown being was calling.

He was stunned for a second, and immediately crawled over to operate.
