What flowed in the river was a pure white nutrient solution that shimmered with a metallic luster, and Su Xing twitched his nose, it was still fruity. The river is home to a large number of small and medium-sized mechanical lifeforms, all of which share a common characteristic: a completely silvery-white shell color.

These mechanical lifeforms, which are mainly aquatic organisms, swim flexibly in the nutrient solution, and in a sense, they seem to represent the stage in the origin of life on Earth from sea to land.

Every few minutes, one or two intermediate stage mechanical lifeforms would crawl out of the river on the section of the river where Su Xing was, lie on the dark brown river bank and wait for the nutrient solution on their bodies to dry, and then transform into various terrestrial forms to be taken away by the staff waiting for them.

"Is it necessary to design it like this?" Su Xing patted the hard toe armor of the steel armor beside him, there was no mystery to him, all he was interested in was this kind of process that was not actually necessary. Obviously, the next generation can be reproduced directly through the combination of fire, why do you deliberately create such a thing similar to the biological evolution chain?

Twisting his neck, the tall mechanical dinosaur transformed into a bald man more than two meters tall in the sound of fine metal rubbing, and he moved his body covered in heavy and gorgeous scale armor a few times, explaining the reason to Su Xing. In the original design, the way in which mechanical lifeforms reproduce the next generation was simply a combination of data and information and the radiation of power from Su Xing, which they called the 'spark source'.

However, after running for a while, this mode was found to have unavoidable flaws, and its stability was really poor. As long as the two sides of the communication are not paying attention, all kinds of chaos will appear, and the descendants born will also have varying degrees of defects. Although these defects can be cured by repairing them after tomorrow, this model has been unanimously eliminated.

The mode of reproduction in operation is now completely different from before, and it seems to be closer to that of humans.

"Each side provides a certain number of packaged feature information codes, and then a specially designed and modified mechanical body transforms into a cultivation center to provide high-energy radiation and a highly active spiritual environment, although this cannot be customized as before, but the safety is more than ten times improved. Because they don't have all sorts of inexplicable mutations for some ridiculous reason. ”

"And the embryos that are born will be put into these rivers for natural elimination, of course, there is a certain bottom line in this, so as to avoid some unlucky guys from getting nothing. ”

Su Xing was embarrassed for a few seconds, and he didn't know how to comment on this kind of thing, and in the end he could only say that he wished them happiness.

"Well, what," he unconsciously ran his finger in a few circles in the air, "you should have a few IM devices for the forward base here, I want to see if there have been any jellyfish on these planets in the past few years." ”

"Your will, primus. ”

The rough and bad road, the uninhabited weeds outside the window, the occasional flashing crooked telephone pole, Duilio pinched the bridge of his nose hard, and there was a lingering feeling of exhaustion.

After arguing for two days and paying the price of three people being hospitalized for the brawl (of course, they don't know how this inexplicable brawl broke out, and some guy who used the ability to amplify emotions hid and snickered), it was only after they decided to target the operation. Calatanaso, a town that has suffered a severe rat infestation.

Duilio closed the window and took out the relevant materials from his briefcase, which he planned to read again from the beginning, but for some reason, he always felt an indescribable sense of disobedience.

Giant rats the size of lambs, villagers attacked, National Guard soldiers who returned in defeat...... These different characters swirled back and forth in his head, making the forty-year-old man restless.

"What's the matter, Duilio?" asked the curly-haired man who had been resting beside him with his eyes closed.

"It's nothing, Reyes, it's just that there are a few things I can't figure out. ”

"There's nothing to worry about, this mission is already weird, you know," Reyes opened his eyes, "and we're going with a brigade of the Army, and it's an armored brigade. ”

"Are you kidding me, Reyes?" he was taken aback, "how could the government agree to send an armored brigade to participate in such an operation, and they still have the money to get those cars moving?"

Reyes didn't answer his question, just pointed upwards and pouted again.

"Well, I see, if it were them, it would be possible to get the bureaucrats moving, but I still don't understand, why did these rats get their attention?"

"That's what we're doing this operation, isn't it?"

A convoy of more than 20 off-road vehicles arrived in the wilderness outside the town of Calatanaso, where the grass was once beautiful and green, but now all that remains is bare soil and huge caves.

"These are the traces left by the rats?"

"Yes, sir. Four days ago, they had destroyed almost more than a square kilometre of grassland, including a small patch of wood. You may not believe it, but it was just twelve rats doing it overnight. ”

"Hey, you mean, are there a lot of rats here?"

"Yes," the young man in the safety helmet gestured to a giant circle, "very, very much, frighteningly much." ”

Carrying his briefcase, Duilio hurried into a camp behind the staff who had received them. Before entering the camp, a somewhat familiar sign flashed out of the corner of his eye, which appeared to be a motif that often appeared on movie screens, and its name was: Autobot, Autobot.

The camp was full of people, busy and orderly. Everywhere there were sealed boxes with equipment and huge containers for unknown purposes.

"It's a pleasure to meet you, doctor. I'm the person in charge here, Arsie. ”

He handed the briefcase to his left hand in a bit of a panic, and reached out his right hand to shake the hand of the lady in front of him with peculiar long bright silver hair, "yes, yes, I'm glad too, I mean," he stammered, "Duilio, professor of biology at Complutense University, nice to meet you, ma'am." ”

"Let's go, I'll take you to see the surveillance footage recorded in the past few days, I think, Professor Duilio, you also want to see those strange lives soon. ”

"Yes, of course. Speaking of this, he immediately burst into good spirits, "Then what are you waiting for, let's go!"
