The little spider wears a pair of black-framed glasses, and looks like a freshman in society who has just graduated from college, and his youthful temperament makes him a talented research assistant who has just graduated, and he is extraordinarily convincing. He put on his long-lost formal clothes, his expression was slightly sluggish, and he looked like a nerd.

It can be regarded as his true character play!

"I'm wearing too many red and blue tights, and I'm almost out of shape when I get used to formal wear!" The little spider silently complained in her heart: "Am I about to become a pervert who loves to wear tights?" ”

Lucius Fox is a thin, middle-aged black man who looks very energetic, he is the CEO of Wayne Enterprises, and one of the few people who knows Bruce Wayne's other identity, he provides technical support for Bruce, and many of Batman's equipment are developed by him.

But in general, he still prefers high-precision machinery, which is not quite in line with the biotechnology that the Lex Group is good at.

He is also a little curious about Peter's identity, Bruce will not explain much for him, although he and Alfred are the two people Bruce trusts the most, but Bruce is a skeptic, he believes that there are no eternal secrets, and there are no people who keep secrets forever, everyone has weaknesses, including himself, and the best protection for them is not to let them know too much.

Therefore, Lucius only knew that the bat needed the spider to infiltrate the secret laboratory of the Lex Group, and he did not know much about the identity of the spider's mission.

"Talk less, you're playing a taciturn image." Lucius explained: "The more you communicate with them, the easier it is to show flaws. You have a bone conduction headset implanted in your right ear, and if you encounter technical difficulties and scientific problems, I will guide you remotely. Don't move around in the lab...... Every small action will reveal your true level...... Academics are hard to fake. ”

"Silent?" The little spider said in her heart: "I think you are embarrassing me, maybe I should play a person who seems to be silent, but has a lot of inner drama." ”

Lucius sighed and said, "For a taciturn person, the expression on your face is too rich!" ”

When passing by a laboratory, the little spider looked at it twice, he obviously wanted to say something, but he was afraid of his own personality, he pressed the essence of his chatterbox, and when he arrived at the office provided by the Lex Group, the spider sensor did not detect any eavesdropping equipment, and the little spider finally couldn't help it.

"Are they engaged in lossless cell replication?"

Peter gushes, "I just saw that they seem to be cultivating stem cells through somatic cells, and they want to restore the functionality of the cells. But they seem to be still in the first step – transforming ordinary human skin cells into new "pluripotent cells" with embryonic stem cell functions. ”

"Huh?" Lucius felt a little dazed, he specialized in electronics and mechanics, biology seemed to span a bit wide, was it okay for common sense and universal research, and for this kind of front-end problem, he could only show a confused and innocent face.

"It seems that the biological research in your world is not very developed!"

The little spider said with some excitement: "The method they use cannot breed universal cells that can be adapted to the human body, because they use retroviruses in the process of genetic recombination. ”

He excites Dr. Lucius and explains, "Reverse transcriptase is a tool for viruses to modify DNA, it is a naturally evolved DNA compilation tool, through which viruses transcribe their own RNA into DNA, which can then use the organelles of the host cell to transcribe, translate, and synthesize the daughter virus...... It's like Lao Wang, who parasitizes on the reproductive system next door and uses the other party's reproductive system to give birth to his own children......"

"I know what retroviruses are!" Hearing the filthy metaphor of the little spider, Lucius couldn't help but interrupt him.

"Oh!" Little Spider didn't know that his unintentional academic discrimination had spurred Dr. Lucius on.

He continued to explain: "Retroviruses are used as tools for genetic recombination, and if the use of viruses as tools is not appropriate, it will cause genetic contamination, that is, it will cause gene mutation, lose the expression of the original cells, and cannot retain the gene expression of the original cells. If that tumor could remain human, he'd look like a toothed ball! ”

"It's like being bitten by a radiated Shar Pei!"

"And ...... It's like the avocado a crocodile baby with another older and disgusting avocado and was disfigured! ”

Lucius couldn't help but imagine the little spider's malicious metaphor, and then he was disgusted, he angrily interrupted the little spider's competition to 'come up with a more disgusting description', and roared: "I know what retroviral recombinant genes cause genetic mutations, and I also know what genetic mutations are. I'm a MIT graduate with a Ph.D., not a parallel trade from a state university, and I'm not a community college idiot! ”

"You don't have to explain these problems to me!"

The little spider was stunned and said, "But I graduated from the state university!" Imperial State University ...... A research university rebuilt after the State University of New York system was destroyed by the apocalypse. ”

"I was still in high school at the time, and I wanted to go to Harvard University because it was the strongest school in the field of biology, but then after hearing about the destruction of the State University of New York system in S.H.I.E.L.D., the U.S. government intended to use its educational resources to rebuild a research university, to study Skynet technology up close, and to cooperate with the leaders and professors of the friendly alien Star Spirit family, Harvard and MIT seemed to be three centuries behind each other. Then I changed the goal of the registration. ”

"Of course, I'm not saying MIT can't, it once trained Dr. Stark! I mean...... Times, yes, times are different. In the face of the challenges of the Big Bang, it is now a little outdated. It can't be with Imperial State University after all...... I mean, it's not a good match for Imperial State University, because we're closest to Skynet, we're working with the Star Spirits, and we're beyond the confines of Earth. Of course, within the earth, I mean among the countries of the earth, Massachusetts is a good university! ”

Lucius was so embarrassed that he almost turned his back on it.

Knowing that she had said the wrong thing, the little spider kept explaining, "Massachusetts is a good school!" ”

"Shut up!" In order to avoid being further humiliated by the little spider, Dr. Lucius could only divert the topic and say, "What's wrong with the research of the Lex Group?" ”

The little spider returned to his familiar field, and vaguely realized that the research level of this world was a little backward, and he became a little excited, talking about his preferred biology, he gushed endlessly: "Looking at the information they have released, they are challenging somatic cell cloning, not using the nucleus and egg cell cloning of somatic cells, but completely using somatic cell cloning." Now the pluripotent cell is only the first step, and they want to use the somatic cells in their hands to create egg cells, which are more versatile than stem cells, and they have to overcome countless difficulties. ”

"Now their biggest headache is the genetic damage of retroviral recombinant DNA, in their research direction...... There is no hope of a solution for five years...... They're on the wrong track! ”

The little spider suddenly realized this: "They are trying to clone a group of specific cells, which has many problems, I can't get the data of that kind of cell, but I can see that the characteristics of that cell are very unique, in some places, such as vitality and genetic mutation, it has a benign promotion for research, the vitality of this cell is very strong, and it will not die easily due to experiments and damage, that is to say, it is very durable, especially suitable for experiments." ”

"But at the same time, retroviruses invading this kind of cell will also be easily eliminated, and they have to be cultured through the symbiotic virus of the cell itself, so this retrovirus has a strong destructive power to genes, and to use a metaphor - replicating this kind of cell is like studying an iron man with steel and iron bones, and ordinary scalpels can't cut the skin at all."

"And then somebody came up with a powerful artillery piece -- that retrovirus."

"Expect to bombard it with artillery, smash the Iron Man to pieces, and then fumble among the corpses to put together a complete human form. And this is just the first step, the ultimate goal is to resurrect Iron Man into two! ”

"Do you have a solution to the problem?" Dr. Lucius heard what the spider meant.

The little spider smiled confidently: "Don't dare to say anything else, retrovirus...... That's what I do. I worked with Dr. Kurt on a way to transcribe lizard's DNA into human DNA, and helped Harry cure his family's genetic disease, a reverse transcriptase virus. ”

Even his superpowers were the result of his father's use of retroviruses as tools to modify his DNA, and the spider's toxin was a genetically modified retrovirus!

Of course, the little spider didn't say this.

"Transcribing the DNA of an animal into a benign expression in the human body, if we still use the metaphor just now, is to dismantle a person in eight pieces, put together the corpse of an animal, and at the last look, that person is not only alive, but also has the ability of an animal. The difficulty is definitely not inferior. So, their headaches, it's a breeze for me! ”

The little spider said confidently: "They just didn't find the scalpel to dissect the iron man, they didn't find the operating enzyme to manipulate the DNA of that cell, I can even predict that that tool is in the retrovirus they cultivated, they just need to transform the cannon into a laser cutting ray knife." ”

Luthor was having a headache in the office, and the progress of cloning Superman in the lab below was really slow, if it weren't for the strong vitality of Superman's cells, they would have exhausted the Superhuman blood and epidermal cells that Luthor had collected without care, and the lab was closed.

There are a lot of problems when it comes to cloning Superman.

The simplest one, at least there must be enough experimental materials, that is, to reproduce superhuman somatic cells non-destructively, and have enough superhuman cells to talk about the next step, the culture of non-destructive cells is not as simple as cell division, even if superhuman cells can resist genetic mutation, in the absence of a human environment, multiple division of somatic cells, the genetic damage caused is also very fatal.

Luthor wanted to clone Superman, not the offspring of Superman's genetic mutation.

To obtain superhuman lossless cells, it is necessary to first restore the function of superhuman cells, that is, totipotent cells—and then develop to induce stem cells. The method of obtaining differentiated cells through stem cells has minimal genetic damage.

But now, if you want to get superhuman stem cells, you must first use retroviruses to recombinate genes, and the damage to genes in the process has reached the level of destruction.

There is no need to divide multiple times, and the cultured cells are simply unusable.

Thinking of the difficulty of the experiment, which could be said to be progressing without progress, Luthor had an urge to grab Superman and take a tube of spinal cord.

It's better if Superman is a woman, then you can arrest her, directly extract her eggs, and then take the nucleus of breast cells and clone hering her...... He's going to catch Superman and clone a ghost!

Did Superman's body cells be stolen while that alien general came to Earth to fight Superman?

Luthor felt tired...... Can't love Superman anymore!
