"Assimilation?" Sigger's face changed, and he subconsciously thought of the Dark Demon Tribe, those Dark Demon people who were infected with the virus.

Without exception, those people were half mechanized, half flesh and blood, and they were very spicy.

"Yes, it's assimilation!" Peter the dwarf said with some despair, looking at his body, "I have been in this world for almost three years, and most of my body is almost assimilated. I guess in a few years, I'll be completely transformed into those robots outside. ”

He said so, but Sieg could see from this man's eyes that he should still be unwilling in his heart.

No one wants to lose their flesh and blood, become a mechanical image that is neither human nor ghost, and can be infected and scrapped by the terrible rust virus at any time.

But when it came to rust, Sieg seemed to think of something, and he then asked, "What happened to the rust before, why did it suddenly disappear just now?"

This is a point that Sig is very puzzled about, the brown rust that originally shrouded the entire city has suddenly receded like a low tide, and the city, which is lifeless as a dying old age, suddenly regained new vitality.

"It's rust, my lord. Peter the Dwarf has been in this world for three years, and knows much more about nature than Siggy, and he turned around with his small mouse-like eyes, and said, "This is a phenomenon unique to this world, and every once in a while, this strange virus called 'Rust Tide' will break out. In the event of an outbreak, all metal objects in this world will be stained with a thick layer of brown rust and fall into a state similar to hibernation. ”

"You can think of this rust tide as the day and night of this world. The dwarf looked up, as if his gaze penetrated the entire underground sewer system: "The sun in this world is an artificial sun, and it will never set, so there is no distinction between day and night here." ”

Sieg nodded, he also noticed that he had been in this world for so long, and it seemed that the sun in the sky had never moved its position, and it had always remained in its original place.

"Therefore, those robots in this world remember the outbreak of the rust tide as night, once the rust tide breaks out, most of them will be corrupted by the rust, in order to preserve energy and strength, except for a very few combat robots responsible for vigilance, most of the robots will turn off the energy and fall into a deep sleep. ”

"After a while, the tide of rust will automatically recede, and then the robots in the city will automatically recover their power and start a new day. The dwarf explained, "It's like day and night in other worlds, and it's a constant cycle. ”

"Day and night. Sieg fell into deep thought. It is true that different worlds calculate day and night differently. For example, in the Black Demon World, day and night are calculated based on the withering and rebirth of the Silver Soul Grass.

He thought for a moment, then his eyes lit up, and the corners of his mouth curled up and said, "Does that mean that once those robots above reach the dark night, they will completely lose their combat effectiveness and become a pile of scrap metal?"

"Uh...... Theoretically, it is. The dwarf nodded, looking at Sig with some fear, he seemed to guess the man's thoughts, and immediately added: "Having said that, even after the outbreak of the rust tide, this world still has basic defense capabilities, and it is said that the control center in the center of this city has an existence that my original owner fears. ”

"Don't worry, I'm not arrogant enough to go against a world. Sieg said so, but no one knew what was going on in his mind.

"By the way, do you know when the next rust wave will break out?" asked Sigurd's most important question.

Now that the outside world has basically woken up, a large number of fierce robots are looking for traces of their intruders, most of these robots are above the first level, and there are even some second-level robots.

It would obviously be unwise to go out now, which is why Sig is ready to wait for the next outbreak of the Rust Virus before going out to look for clues.

However, the dwarf Peter shook his head helplessly, and said with a somewhat depressed face: "The outbreak time of this rust tide is useless, let alone me, even those powerful robots in this world, there is no way to calculate the time point of the next rust tide." ”

"It may take more than ten days, it may take years, it may take tens or hundreds of years, and of course, it may be the next second. The dwarf said, shaking his head.

At this moment, the sewer river was filled with pungent heavy metal wastewater, and the two figures stopped for a while and began to think about countermeasures to each other.

"What is the timing of the irregular eruption......" Sigurt touched his chin, but the thoughts in his heart flew up.

If you're unlucky, the next Rust Tide will hit a few decades later, and then you'll be completely assimilated into a robot like this dwarf.

"In other words, we have no way of knowing exactly when this rust tide will erupt. Sieg said secretly: "It seems that it is still up to me." ”

He felt that instead of hiding in the sewers and waiting for this ethereal tide of rust to break out, he should take the initiative and find the opportunity to escape!

Not to mention...... Inside the sewer, it's not necessarily safe!

Squeak squeak.

A mechanical rat scurls through the stinking sewers, their eyes glowing crimson.

"Discover the target, discover the target!"

A subtle sound passed through the body of the little mouse, a sound similar to electromagnetic waves, silently passing through the underground water system made of reinforced concrete to the ears of many combat robots searching for the intruder above.

"Intruder found, intruder found!"

All of a sudden, like hungry wolves smelling meat, these robots began to gather towards the underground waterway where Sigur and the others were.

"I felt a hint of danger looming at us. On a path on the right side of the riverbed, Sieg suddenly stopped, a helpless wry smile on his face.

What should come will always come.

His ears could clearly hear more and more roars from above, all of which were coming from around him without exception.

"If I'm not mistaken, it's supposed to be the sound that those crawler robots make when they walk. Sieg shrugged at Peter, the dwarf next to him, and smiled helplessly, "We may have been surrounded." ”

"No......" The red-nosed dwarf's forehead began to break out in a cold sweat, and this thin and somewhat short human had a cowardly expression on his face.
