On the edge of the continent of the Atlanta world, in the cold void, Cassia was working cross-legged, and a notebook floated beside him, on which words appeared from time to time to record something.

In front of him, it was the edge of the entire continent, which was different from the perspective in perception, and when Cassia came here to check it out in person, he really felt the heaviness of this circular continent.

If you look up or down from the side of the circular continent with the naked eye alone, you can barely see the end, it is like an infinite wall, standing in front of you.

Cassia has been here quietly for three days, and he has been facing the wall for three days, but he still has gained very little.

The reason for this is that it all started a few days ago, when Cassia decided that the last two sapient races would be dragons and elves, and in doing so, he wanted to find a way to increase their lifespan.

But because the creation of spirits is more troublesome, it is necessary to deal not only with the problem of long lifespan, but also with the characteristics of being close to nature.

If it was just to be close to nature, Cassia could be achieved with soul interference, so that they were born to love, but if he remembered correctly, the elf should have grown from a tree, which was a hallmark of the elf, so he decided to keep it as it was.

But how to make a tree grow elves has become a problem that needs to be solved.

Later, after thinking about it for a long time, Cassia still didn't have a good way, so he simply prepared to create the dragon first.

He had already summarized all the designs of the dragon, including the body structure, the types of organs, the selection of ability inserts, and the selection of abilities, which were basically designed according to the image of the dragon in the stories he had heard.

If all of this can be achieved, the dragon will be the most capable creature in the Atlantic world, and the dragon will be one of the top races on the continent.

Therefore, the question of longevity became the only obstacle to the creation of dragons.

At first, Cassia racked his brains, and he couldn't think of any good way to fundamentally extend the lifespan of the species, and although those biological ability plug-ins were also suitable for extending life, they were still far from the level of dragons.

It wasn't until he returned to the real world to change his mind, and while cleaning, he found out his previous case of stomach cancer, and Cassia suddenly realized that when he had really seen the whole world of Atlanta, he had a strange guess.

Cassia discovers that in the Atlantic world, what he calls creating out of thin air is nothing more than changing molecules, or changing atoms with the help of world authority, to achieve the purpose of creating out of thin air.

But this ability is essentially just a change in the form of matter, and it is not something out of nothing, except for this continent, of course.

This continent is already very large, but it can still continue to expand under the control of Cassia consuming spirit points, and the point is here.

Continental expansion requires the creation of land, but where does this soil come from? Other material transformations? Cassia did not discover this process, and according to his observation, when the continental edge expanded outward, those substances did indeed come into being out of nothing.

At that time, Cassia couldn't help but think of cancer cells and soil.

One is diseased cells that can divide indefinitely.

One is the legendary sacred land that can grow indefinitely.

However, it is impossible to tell whether it is cassia or not, but after such a long time, he feels that the cancer cells are still reliable.

So the moment he saw the medical records, Cassia couldn't bother to clean up half of the room, and sat directly on the chair, and his spirit entered the Atlantic world.

After coming to the Moon Palace, he didn't care about anything else, so he picked up his notebook and came to the edge of the entire continent, and this sitting was three days.

"Whew...... What should I do?" Cassia scratched his head, reached out to hold the notebook, and carefully combed through the results of his three days.

The first thing that can be confirmed is that when the continent expands, its marginal material is really formed out of thin air, and then new land is formed.

But to Cassia's surprise, with his current world authority, he couldn't decipher the meaning of this, that is, he couldn't figure out what these marginal substances were and why they could be created out of nothing.

Cassia has also gone deep into the database of the Atlantic world, but the data on this aspect is not clearly expressed, and in some places it is even a mess of garbled characters.

Looking at the questions recorded in the notebook, Cassia reached out again and tried to isolate some edge matter, but unfortunately failed again, even if he consumed spirit points, the permission command was like a mud cow into the sea, without a trace.

Cassia then left the place with some loss and returned to the Moon Palace, where he thought he could use these marginal substances to create dragons and elves, and even try to create a body for himself.

Cassia on the stone chair of the Moon Palace shook his head and put a cross and question mark on his notebook.

This meant that the plan had failed, and he thought he had eaten the Atlantic world, but he didn't expect that there was something in it that he couldn't reach.

"What the hell is this, is my authority still on the verge of being elevated?" Cassia guessed.

"No, why do I have to use these substances to create dragons? Even if I can isolate some, I can't use it to create life, well, it's too rushed, I'm still too anxious. ”

Cassia frowned and thought about it: "Out of nowhere, cancer cells, infinite division, infinite division...... Infinite ......"

Suddenly, Cassia raised his head violently and muttered: "I can explore and study the marginal materials of the continent later, but the reason why living things have a lifespan limit, in addition to diseases, the most important thing is the number of cell divisions." ”

"When organisms enter old age, the number of cell divisions decreases, and there is not enough supply of new cells, the physical body of organisms will age, yes, yes, yes, you can start from this aspect. ”

Cassia was overjoyed like a child who had taken a little red flower in kindergarten, got up a few steps and stepped to the third floor, waving his hand to open the dragon gene template that had been configured a long time ago, and his eyes seemed to be about to burst out of a strange green light.

"Telomerase, telomerase, where did it come from, I remember the ...... I encountered"

Cassia muttered in his mouth, pulling his hands together, enlarging and dismantling the genetic template in front of him, trying to find the part that controls the telomerase enzyme.

And in the flash of inspiration just now, he remembered the reason why biological cells divide less, and that is telomeres.

Telomeres are located at the ends of chromosomes and become shorter with the increase in the number of cell divisions, and when telomeres become shorter and shorter, it becomes more and more difficult for chromosomes to replicate and divide cells, and the flesh will age.

What if you don't make telomeres shorter? Just like cancer cells, the reason why cancer cells can divide indefinitely is because of the protection of telomerase, which has the function of repairing and growing telomeres, and telomeres will not become shorter, and cancer cells will not divide without taking care of it.

Taking the human body as an example, the activity of telomerase is strictly controlled in most cells of normal people, and only a small amount of activity can be detected in stem cells and hematopoietic cells.

"Since telomerase in hematopoietic cells can be active, I can modify the gene sequence so that the telomerase in all cells is active, as long as the activity can be maintained at a certain level, and it will slowly weaken over time. ”

"In this way, the rate of telomere shortening can be extended, the number of cell divisions can be greatly increased, and the aging of the flesh will naturally be slow...... Found it!"

..................

Two months have passed, and at this time, Brother Diao is pecking at the cassia notebook on the first floor, as if he feels that there is a cassia breath on it.

In fact, Brother Diao knew that in the past two months, Cassia was on the third floor of the Moon Palace, but he had never seen him come down once, and Brother Diao originally wanted to steal some nutrient solution, but the door on the third floor was locked, and the windows were also sealed, so she really couldn't get in.

Da, da, da.

Brother Eagle pecked at the stone table in a moment, hoping to attract Cassia so that she could go in and drink a little nutrient solution.

There was a rustle, a heavy stone door grinding sounded, and Cassia walked down from the third floor tiredly, but his eyes were full of joy.

When the eagle brother next to him saw that Cassia had really come down, he hurriedly slowed down and moved towards the third floor little by little.

Suddenly, a beast roar came from the stairs, and immediately Brother Eagle saw a winged lizard, flying crookedly from above, and fell down the stairs with a clatter.

Brother Eagle rolled his eyes humanely, ignored it, and continued to walk towards the third floor.

Cassia, who was sitting on the stone chair, was attracted by the sound, turned his head and beckoned the 'lizard' to his side, his face full of joy.

This is the first dragon cub in the Atlanta world, using the genes of a variety of animals, wide wings, tough claws, like the head of a dinosaur, almost the same as the dragon in Western mythology.

The cub who landed on the stone table seemed to be a little frightened, and after yelling at Cassia twice, he suddenly coughed, a little spark came out of his mouth, and two more puffs of black smoke.

Cassia smiled and stroked the top of its head, temporarily letting it fall asleep.

The birth of this fire-attribute dragon also means that Cassia has been successful in his experiment.

In terms of prolonging life, Cassia still uses viral infection to immobilize the gene that controls telomerase activity on the main sequence with a psychomarker.

And set a weakening mechanism on the mental marker, as the dragon ages, the spiritual marker connected to the active enzyme gene will continue to weaken, and finally will fall off completely, and at that moment, the life of a giant dragon will come to an end.

The detached markers will not dissipate, but will be evenly scored by the database for the most recently born next generation.

In this way, theoretically, the size limit of an adult dragon is 100 meters, and the lifespan limit is 1200 years, but because they will produce offspring and have extremely low fertility, the average lifespan limit of the developed dragon race will be stable at about 1000 years.

"Whew...... It's done, no, I'm going back to sleep for a while. ”

Looking at the sleeping red dragon cub on the table, Cassia muttered to himself tiredly, and the figure disappeared into the Moon Palace.
