"No, no, no, we have basically abandoned the practice of drilling holes in the vertebrae, injecting drugs or implanting chips - this set of technology is too backward, basically, it is a product of ten or twenty years ago, and we now mainly use the method of molecular penetration to accurately deliver the agent directly to the target organ."

Xie Xiaolei regained a little of his demeanor and said with a smile, "Please, I'll take Meng Chao to visit our concoction laboratory." ”

On the surface, "Lingchuang" is just an inconspicuous seven-story small building and an outbuildings.

But underground, there is a huge laboratory.

In addition to modulating biochemical pet animals of the canine and feline families.

There are also giant sandworms with a length of more than 30 meters, which are modified here, implanted with artificial hormone sacs and various control chips.

"Don't worry, the giant sandworm is a very tame fellow."

Seeing Meng Chao staring intently at the ring-shaped sharp teeth of the giant sandworm on the preparation table, Xie Xiaolei explained with a smile, "In fact, the more low-level monsters, no matter how hideous and terrifying they look, the lower their danger factor, because they can't think, have no consciousness, and don't know what they're doing, and it's even difficult to distinguish the difference between humans, other monsters, spiritual plants, rocks, and fortresses, but under the guidance of instinct, they keep devouring, devouring, devouring."

"So, as long as we can release special biocurrents or hormones that stimulate their nerve clusters, we can control their instincts and make them serve humans.

"It's a flesh-and-blood machine, and it will never hurt its owner."

Meng Chao nodded.

He remembered.

The Mr. Xie in front of him is a genius of advertising.

In the initial stage of "Spirit Creation", in order to verify the safety of the biochemical beast, he once personally starred in a very famous advertisement.

In the advertisement, he stood in the bloody mouth of a giant sandworm with a smile, holding a glass of wine gracefully, preaching the superiority of genetic modulation technology, and even using an electric baton to stimulate the mouth of the giant sandworm.

The giant sandworm always obediently opened its mouth and did not devour him in one gulp.

This advertisement caused heated discussions, and also opened up the situation for "Lingchuang".

However, today's focus of Meng Chao's concern is not the giant sandworm, but the small and medium-sized biochemical pet beasts raised by the family.

"Here, please, the three biochemical pet beasts that had an accident this time belong to our third-generation products, and they have a certain combat effectiveness and extremely high intelligence, so we also pay special attention to safety."

Xie Xiaolei said, "The preparation of this generation of products is mainly divided into three steps: first, the use of genetically engineered nucleases, that is, 'molecular scissors', to generate site-specific double-strand breaks at specific locations in the genome, inducing organisms to repair double-strand breaks through non-homologous end joining or homologous recombination.

"This repair process is error-prone and leads to targeted mutations – and that targeted mutation is gene editing.

"Through gene editing, we can fuse the characteristics of dozens of canine monsters together, and knock out the gene fragments that control their desire to hunt and kill, and then implant the genes of some more docile herbivore monsters.

"Hmmm......"

Meng Chao thought thoughtfully, "It sounds complicated, will it be very unstable?" ”

"How come, this is a very mature technology, in the Earth Age, even elementary school students can carry out experiments related to gene knockout, not to mention that we have come to such a new world with abundant aura and constant changes, in just half a century, our pace of exploring the mysteries of genes is five hundred years more advanced than the Earth Age!"

Xie Xiaolei said, "Moreover, the genes of otherworldly monsters ...... How to say, we have found a lot of traces of cutting, knocking out and encapsulation in the genetic chain of many wild monsters, they do not look like pure beasts, but like products in the laboratory, of course, a long time ago, maybe thousands of years ago. ”

Meng Chao said: "What? ”

Xie Xiaolei spread his hands and said: "There was once a very advanced primeval civilization in the other world, and this is not a secret, since human beings have thought of using genetic technology to explore the maximum potential of animals and plants, there is no reason why the primeval civilization in the other world can't think of it."

"The truth here, just leave it for historians and archaeologists to study slowly, I just want to tell you that monsters are originally a very easy to modulate creatures, otherwise, how did you think that so many fierce and extremely combat-type biochemical beasts in the Nongda Beast Control Department came from?

"Of course, gene editing is only our first procedure, and then, while the cyborg is still in its mother's womb, we inject various hormones and agents in advance to ensure that its brain grows faster – brain volume is not a problem, it is a sulcus.

"Scientific research has proved that brain capacity is not the key to determining wisdom, the number of brain grooves and circuits is crucial, after our modulated canine biochemical beasts, brain circuits can be 300% more than wild canine monsters, enough for them to master the intelligence of seven or eight-year-old children, can understand some simple orders of the owner, of course, also know how to choose, in order to survive more comfortably in human society.

"The injection of the medicine is not once, but in its entire modulation cycle, it will be carried out nineteen times, in addition to promoting brain growth, there is also an inhibitory hormone, which can curb its ferocity to the greatest extent, and now the biochemical pet beast is more harmless than a pet dog."

Xie Xiaolei paused when he said this.

Obviously, he was overwhelmed by the events of the past two days, and his mood was not as good as his expression.

Seeing the "own people" from the Agricultural University, I couldn't help but complain: "Say something that I shouldn't say as an identity, even pet dogs in the earth era, there are endless incidents of hurting people, I haven't heard that because of a pet dog out of control incident, all pet dogs will be killed, right?" ”

Meng Chao narrowed his eyes: "Mr. Xie, what do you mean is that it is still possible that the product concocted by 'Lingchuang' is out of control?" ”

Xie Xiaolei's face flushed, and he hurriedly defended: "No, no, no, I just said, we can't waste food because of choking, biochemical technology is the key for us to colonize the other world, after all, the mechanical failure rate of this world is too high, and the spiritual energy, as the main energy source, is also too unstable, if because of an accident, we will cut off our hope of concocting monsters, it will be too arbitrary."

"It's like rune machinery, it's not without accidents, when building the No. 6 underground rail transit line, the big explosion and the collapse, causing a building on the ground to collapse as a whole, killing and injuring hundreds of people, and finally found out that it was the manufacturer of construction machinery, and it didn't understand the real power contained in an ancient rune, so that two different spiritual magnetic fields collided with each other, which caused a tragedy - we didn't take the opportunity to make trouble, saying that rune technology is a dangerous product that will threaten the entire civilization!

"I'm sorry, it's far away, Meng Chao, please see, this is our third modulation program, and it is also the last safety measure, we have implanted a chip in the central nervous system of all biochemical pet beasts to monitor the hormone level of biochemical pet beasts at any time.

"When the chip detects that the hormone level of the biochemical pet beast is abnormally increased and enters a state of rage, it will automatically release a very strong biological current to deliver a painful electric shock to the biochemical pet beast.

"If it can't calm down, the intensity of the shock will continue to increase, and in the end, it may even burn out its central nervous system.

"Please come to the laboratory here, we can witness with our own eyes and control the power of the chip."

Xie Xiaolei said, inviting Meng Chao and Ning She to a floor-to-ceiling glass window.

Behind the glass window, there is a kennel, locked up with a biochemical pet beast of the same type as this accident.

This kind of biochemical pet beast with the internal code name "Saihu" does have the beautiful appearance of a little tiger and a majestic bearing.

Its body is slender, streamlined, its golden fur is shiny, but it can't hide the explosive power brought by the muscles and flex, usually the fangs and claws are deeply converged, and it pops out like a dagger when fighting, and in the face of ordinary monsters, it can be entangled for a while, and when it encounters its master being crushed under the ruins, it can also dig as fast as a drilling machine.

In the age of the earth, when people choose pet dogs, they often like small dogs that are petite and delicate, and have a cute appearance.

But Dragon City is a lone army in a foreign land, in the land of a hundred battles, all the citizens have broken through from the rain of bullets, and they will have to experience endless battles in the future.

In this iron-blooded society where martial arts are respected, people keep pets, and they also prefer this kind of powerful, domineering, and large dogs with a certain combat effectiveness.

There are even people who don't like war dogs and breed more ferocious carnivorous lizard-like monsters, which is gradually becoming a trend.

"Saihu" is a hot-selling product of "Lingchuang", Meng Chao has seen a lot on the street in the past, and he is all stupid and stupid, and he feels very secure at first glance.

But the "Race Tiger" in front of him had red eyes, salivating at the corners of his mouth, his head twitched nervously, his fangs and claws shrank and stretched, and he looked fierce.

Xie Xiaolei told Meng Chao that in order to test the danger of "Saihu", they have conducted many experiments in the past two days, and the biochemical pet beast in front of him has inhaled a large amount of irritating gases and injected a crazy medicine carrying germs, which is about to restore the ferocity of the monster.

"Injecting the madness potion can restore the ferocity of the originally tame biochemical beast?" Meng Chao was thoughtful.

"Of course, it's a brute after all."

Xie Xiaolei said, "Not to mention biochemical pet beasts, even if humans are injected with drugs that carry the 'zombie virus', they will also become zombies, showing their teeth and claws, and their relatives will not recognize them - this has nothing to do with the safety of the product." ”

As he spoke, a piece of blood-drenched raw meat hung down in the laboratory.

The biochemical pet beast looked fierce and immediately pounced.
