In the depths of the base is a separate ecological park, which is full of high-intensity radiation. Needless to say, it's for the last tribe of rot-clawed lizardmen.

Out of consideration for the research and development of anti-aging agents, the last batch of rot-clawed lizardmen on the Blue Star were left by Qin Feng and captured here to be kept in captivity, slowly forming a small tribe.

Later, when exterminating the rot-clawed lizardman empire on the other side of the natural wormhole, Qin Feng managed to retain a group of more powerful individuals, and sent them back to prison after banning their powers.

Up to now, there are still more than 20,000 rot-clawed lizardmen left in the ecological park, and every day, they are drawn blood, extracted from various body fluids, tissue and gene fragments for research, and sometimes they are poured with various experimental drugs of unknown use, and then imprisoned in cages to observe the pharmacological reaction process.

Over the years, tens of thousands of rotting clawed lizardmen have been tortured to death, and of course, their sacrifices have brought rich rewards, and many of the new genetic drugs launched by the Imperial Academy of Sciences are the contributions of this group of aliens.

"Your Majesty, please see, this is the latest anti-aging agent developed in the laboratory,"

The lieutenant general took a thumb-thick dark golden crystal test tube and explained: "As long as it is injected, it can increase the longevity of ordinary people for a hundred years, and the effect is more stable and reliable, it can be used at most twice, before the end of life, the user will basically not have obvious aging, and can always maintain the peak physical state of twenty or thirty years old." ”

Qin Feng bowed slightly, it can have such a significant effect on ordinary people, it can be seen that this potion is indeed extraordinary. In contrast, due to the strong vitality of the evolutionary and the longer lifespan, it is less difficult to develop anti-aging drugs suitable for their use.

Therefore, the latest research results of the Imperial Academy of Sciences, anti-aging drugs suitable for high-level evolutionaries can allow users to live for up to eight hundred years, and if it is ten years later, this upper limit of longevity is expected to break through the thousand-year mark, as long as the supply of genetic materials for high-level Warcraft species from the Xingmeng World continues to be extinct.

For the human civilization individuals on the Blue Star, being able to obtain such a long life span is indeed a luxury that they could not have imagined in the past. However, for the daughters of Lin Xihan who have reached the starry world, this lifespan is nothing.

"It seems that even if you just take the route of technological civilization evolution, the upper limit of human lifespan has a chance to increase all the time, right? Is it even possible to get close to eternal life? Qin Feng asked.

The lieutenant general shook his head: "At present, it seems that it is unlikely, there will definitely be a certain theoretical ceiling, I personally estimate that it will be three or five thousand years, no matter how high it is, I am afraid it will be impossible, unless there is a milestone change in the theoretical system of gene science and technology." ”

Qin Feng was silent, of course, the lieutenant general's analysis was not a mouthful, but a rational speculation based on the current level of science and technology.

For example, archaeologists have dug up countless fossils of ancient organisms from the ground, from thousands of years ago mammoth fossils to hundreds of millions of years ago trilobite fossils, but they are only stone specimens, and still active DNA gene samples have not been found.

Because according to the research and demonstration of scientists, unless extremely perfect and advanced preservation measures are taken, carbon-based biological genes also have a "half-life", except for a very small number of biological DNA fragments, which can exist for more than a million years under certain circumstances, the half-life of DNA base pairs of most species is only about 150,000 years.

If this age is exceeded, all the genetic information carried in the DNA fragment will gradually disintegrate, be lost, and no longer have the value of research and cloning.

Therefore, even if the Empire's level of genetic technology can continue to develop, and the genes of higher species from the Star World continue to be supplied, it is powerless to increase the upper limit of human lifespan without limit.

Unless you are like the demigods of the starry world, you can condense your divinity, collect the power of faith, and obtain the godhead as a god, you can have a longer youth. Of course, if it was the cultivation civilization of the Yuan Luo Realm Heaven, that body would naturally be able to live longer.

With the example of the apocalyptic world in the past, it is estimated that the development process of the main world in the genetic field in the future will be similar, which shows that the technological civilization in some aspects really cannot be compared with the cultivation civilization.

"Well, you don't have to rush this matter, just take your time."

Qin Feng said, he didn't need this thing himself, and Lin Xihan didn't need it, as for the other imperial ministers and high-level evolutionaries, they still had enough time, so they didn't need to bother too much, just let it be.

After the inspection was completed, Qin Feng returned to the palace, briefly said a few words to the girls, and the figure disappeared in place.

When he reappeared, he had already come to the mysterious space where the planet's will Qin Jian was sleeping.

Compared to the last time I came here, this place has expanded a lot, with a hemispherical space of tens of thousands of meters, surrounded by a barrier formed by cyan clouds and light on all sides, and a rich aura energy permeates the surroundings.

In the central area of space, a bright light cocoon was suspended, and Qin Jian was sleeping inside, working hard to evolve into a star domain-level will as soon as possible.

"It looks like it's almost there, I'll help you add another fire!"

Qin Feng said and waved his hand, a high-level demon beast from the Yuanluo Realm Heaven was relic, a magic weapon, recording the jade slip and immortal elixir of the high-level Dao magic power...... Thousands of high-level sacrifices were thrown out.

As the cyan clouds flickered, these precious sacrifices from the higher time and space were absorbed and digested by the power of space one by one, and a large number of world origins were fed back, and the figure of Qin Mian inside moved slightly, and the spirit and spirit were rising at a dazzling speed.

When the sacrifice was over, Qin Feng finally opened his eyes, as if the entire space was lit up, and when he looked directly at her face, Qin Feng, who was accustomed to seeing stunning colors, lost his mind for a moment.

"Your Majesty, you're back!"

Qin Yan's figure flashed, and he had already thrown himself into his arms, and the two of them made love for a while, and then they stopped unfinished and recounted their experiences after separation.

"Since it's already a star domain-level will, now you can leave the solar system and go to other star fields, right?" Qin Feng asked.

"Absolutely."

"Okay, let's go now, can we go to those planets to find opportunities?"

Qin Feng proposed, he remembered that Qin Jian said that theoretically, it is possible to conceive the planet's self-consciousness inside each big planet, so as to give birth to the planet's will, but in fact, there are very few planets that can achieve this, and most planets only have some evolutionary energy accumulated inside, and it is basically impossible to generate independent consciousness without special chances.

"Okay."

Qin Jian nodded excitedly, she remembered that the last time she left Blue Star to go near the natural wormhole, the eight planets of the solar system along the way were all searched by her and Qin Feng, and they harvested countless essences of evolutionary energy, and this time they were obviously able to eat a full meal again!
