According to the relevant laws and regulations of the top of Kunlun, the domain of the vassal king is not fixed.

The area within a radius of 300 kilometers is only the basic level. And it is up to the vassal king to find a way to fight it down by himself, and the top of Kunlun will not come forward, at most to provide some help in the back, and it is not gratuitous.

Of course, after the powerful vassal king has gained a foothold, he will think about further expanding his territory, and the top of Kunlun basically doesn't care about this, as long as you can defend it.

However, there have also been examples in history of unexpectedly fallen vassal kings, because there were no good enough sons in the descendants to take over the power, resulting in the kings and territories being recovered by the top of Kunlun. After all, this world pursues the absolute law of the jungle, and the consequence of losing power is that everything you have will be taken away by others, and there is no fluke.

Qin Feng was now a true vassal king, with a territory and army commensurate with his status, as well as financial resources far superior to those of other vassal kings. In the eyes of the top management of Kunlun, it is already a hot upstart.

“…… His Royal Highness the Prince. ”

Tang Ning walked in at some point, and said warmly after bowing slightly: "Xiao Yuehan and the others have already returned, I heard that it was a big victory, and none of the remnants of the Song family have escaped the net." ”

Qin Feng came to his senses and said, "Then let her rest and then report back, well, it looks like it's about to rain outside." Inform the soldiers who are on patrol duty to be careful, and if they cannot find the nearest hidden place, they can consider withdrawing first. ”

Outside the huge floor-to-ceiling windows, the sky is as dark as the bottom of a pot, which is a sign of an impending storm.

The rain of this era was mixed with a large amount of strong radiation dust, and even the low-level evolutionaries without protective measures could not bear it, even the middle-level evolutionaries, if they did not take effective treatment in time after the rain, they would basically not last for three days, and they would be weakened, festered and bleeding to death.

Therefore, as long as it rains, there will rarely be military action between these bases and the family forces, and the cost is too great.

However, the soldiers under Qin Feng's command are now equipped with sufficiently advanced combat vehicles and potions, and they are no longer afraid of this kind of radiation rain that has been talked about in the past.

Tang Ning agreed, turned around and walked out.

Qin Feng slowly paced to the floor-to-ceiling window, which was the place that once belonged to the head of the Song family, and every detail was arranged with ingenuity, revealing luxury in a low-key manner. Clean glass is a new polymer composite material, which has many effects such as bulletproof, sound insulation, anti-reconnaissance, and radiation shielding, and the cost is naturally amazing.

The scene outside the window has been seen many times, and there is nothing new about it. Beyond the hills in the distance, a few dozen kilometers later, there is a vast sea. A seemingly nonexistent pressure shrouded in a faint aura of violence and blood, so that all species on land did not dare to get too close.

The territory of the Song family is close to the sea, and it has existed for a long time, but there has never been a large-scale exploration and development of this area near the sea. Even before the catastrophe, the seaside urban agglomeration was the most prosperous and developed area, and there were countless good things hidden inside.

It is now home to countless mutant species, and there are many tribes of alien sapient species entrenched deep in the ruins of the city. Qin Feng's divine thoughts swept at will, and he could detect a lot of alien breaths dormant.

"The fifteenth-order perception domain ability is really extraordinary."

Qin Feng pondered silently, after taking the Blood City that day, he took the lead in raising the ability of the perception domain to the fifteenth order, at the cost of the world origin of more than ten thousand. The reward is centered on his body, and all the wind and grass within a radius of 250 kilometers cannot escape his insight and perception.

Therefore, when he was in the Song family's headquarters, he was able to know the movements on the beach well, including some of the conditions on the sea.

It can be seen that the vast ocean has now been completely reduced to the territory of the alien intelligent species.

In other words, in the war with the alien race, the alien race has a great advantage. After all, the area of the ocean is much larger than the land, and even on land, the power of human civilization has not been able to completely suppress the alien race.

Qin Feng had imagined more than once that when one day in the future, countless alien intelligent species came out of the sea, harnessed all kinds of strange weapons, and attacked the forces of human civilization on land, whether the top of Kunlun would be able to resist it.

Maybe human civilization will really die out because of this, and thus give up the dominion of this planet?

Communicating with the Starship Hub, he found that the value of the World Origin had reached more than 45,000, plus the 10,000 Origin that had been consumed, which was the result of his hard work in the past few months.

Expanding his territory, collecting meteorite fragments, and cleaning up the alien races in the territory of those families, especially the tribe of rotten-clawed lizardmen hidden in the ruins of many cities, every task is not easy, and of course, the rich rewards are fully worth his hard work.

Now, except for the territory of the Song family, as well as the area near the sea, it can be said that his territory is unprecedentedly "clean", and all the alien wisdom species, as well as the mutant species above level ten, have been killed.

Several large cold stores in the city of frost and fire are full, and of course the most valuable parts have been devoured by the starships. The rest can be sent to the biochemical laboratory to refine and make various high-grade genetic drugs. Some types, even the top of Kunlun have offered quite high prices for long-term acquisitions.

"Let's do genetic optimization again......"

Qin Feng pondered, after he had advanced to the fifteenth level of evolutionary, the Starship Hub had already opened up a higher level of authority to him.

"Grade A Genetic Optimization. It can make the master's overall physical quality improve in an all-round way, with the level of the Great Chu World Heavenly Immortal and the Sixteenth Level Evolutionary of the Doomsday World, the spiritual power is strengthened by 120%, and the lifespan is increased by 100%, and the World Origin is required: 6400. ”

The price of the last B-level genetic optimization was 1600 origins, and this time it has been quadrupled, and the price will only become more and more exaggerated in the future, maybe you will have to wait until the next world to have a chance.

"At the level of the Great Chu World, there shouldn't be any Heavenly Immortal Progression, right?"

Qin Feng asked suspiciously, the oldest classics in those cultivation sects only had records about true immortals, and they had only appeared in the golden age of ancient monks. As for the immortals, it seems that there is no such concept at all.

"Yes, the will of the world is the only immortal-level existence, but it does not belong to a monk in the ordinary sense, and the true body has never descended." Starship Hub explained.

"Then, in other more powerful worlds, there should be more than one immortal-level existence, right?"

"Indeed, there is no shortage of beings more powerful than the Heavenly Immortals."

"Understood."

Qin Feng didn't say anything anymore, and silently chose to be sure.

The dazzling yet heavy golden light started from his heart, and seemed to spread slowly and quickly throughout his body, and a faint coercion permeated the space.

The energy essence in the void gathered like a tide, was transformed and purified by the starship center, and then injected into his body, comprehensively optimizing and improving him from the genetic cell level.

In order for the subjects to be optimized to gradually adapt to their own changes, the genetic optimization will last for fifteen days before it is truly completed.

At that time, he will have a body at the level of an immortal, but if he wants to be promoted to a true immortal by his own cultivation, he can't hope for the time being, maybe it will be possible after entering the next world.

According to the classification criteria given by the starship hub, the A-level genetic optimization technology still belongs to the scientific and technological level of the second-level interstellar civilization, of course...... It's the advanced stage.

The primary interstellar civilization refers to the civilization in which the intelligent life on the planet can freely leave the home star and set foot on other planets within the entire star system, and can establish a number of large-scale scientific research bases on it, and can exploit and utilize various resources in the entire star system on a large scale.

The second-level interstellar civilization refers to the civilization that intelligent life has the technical means beyond the speed of light, the scope of activity covers the entire star field, and the ability to develop and utilize many resources in the entire star field.

Before the catastrophe of this world, human civilization was close to the level of primary interstellar civilization, but unfortunately it was pushed to the brink of near destruction by the sudden catastrophe, and it has not been able to ease its strength until now.

"Genetic optimization technology seems to have a tendency to weaken the effect of prolonging life?" Qin Feng asked.

The last genetic optimization increased life expectancy by 150%, and it was cumulatively added on the basis of the previous level, but this time it only increased by 100%, and the future increase is estimated to be even less.

"That's right, there is a theoretical limit to the genetic optimization technology for carbon-based life, and it is impossible to improve it indefinitely, unless it opens up new evolutionary pathways." Starship Hub said.

What is the new evolutionary pathway, Qin Feng did not continue to ask, this is obviously not what he is capable of involving now.

More information poured into my mind from Starship Hub, and more new options appeared:

"Dark Nightmare Mechanical War Beast. With the strength equivalent to a level 12 melee combat evolutionary, he absolutely obeys the master's orders and needs the World Origin: 800. ”

"Heart of Gaia's defense base. It can operate stably for a long time in a complex environment with high threat, can accommodate a hundred fighters on a permanent basis, and is equipped with main battle equipment such as heavy artillery, electromagnetic guns, and cruise missiles, and requires the origin of the world: 3500. ”

"The Wrath of the Planet hovership. It can go back and forth to the ground and the planet synchronous orbit at will, with a standard crew of thirty-five people, a maximum load of five hundred tons, and weapons such as electromagnetic destruction cannons, particle cannons, and high-power lasers, and the need for the origin of the world: 6400,. ”

"The Song of Life. To allow the aging rate of the master's body to stop indefinitely within twenty years, it requires the World Origin: 2500. The selection can be repeated up to 20 times. ”

"Extradimensional Barrier (Strengthened). Personal protective equipment, which can resist the full attack of a level 15 evolutionary, lasts for 500 seconds, and requires World Origin: 4000. ”

“……”

This time the permission upgrade has made the list of options more abundant, such as many genetic ability potions above the twelfth order, and there is everything in the list. It can be exchanged up to the fifteenth order, which is a strategic-level resource that is extremely difficult to synthesize at the top of Kunlun at present, and it is impossible to get a few in a year, and those big names in the core decision-making level are not enough, let alone outsiders.
