A few days later, when Chen Xing saw the curved glass roof of the No. 27 Security Station, he almost fell to the ground. In order to get back as soon as possible, they only slept a few hours a day and did their best to get on the road.

During the disinfection shower, Chen Xing fell asleep twice. Changing into a white jumper, he casually drank some rice porridge, and without saying hello to the big cat, he ran upstairs directly, got into the sleeping pod, and slept with his head covered. Excessive physical exertion and mental expenditure made him physically and mentally exhausted, and he slept for two days and two nights in a row.

At noon on the third day, Chen Xing crawled out of the sleep pod weakly, asked the robot to send a bottle of glucose supplement, and filled half a bottle before he could barely stand up.

Going down to the rest area, Chen Xing made a big bowl of rice porridge, drank it with pickles and sour radish, sat for a while, and finally recovered his spirits. The big cat came down a few hours before him, had already finished his lunch, and went for a swim in the underground training grounds.

There are four floors in the security station, and the second underground floor is the system area, where the armed robots are repaired and stored, and it is also a forbidden area for exiles; The basement floor is the training center, the ground floor is the rest area, and the second floor is the sleep center.

The training center has a variety of training equipment, as well as swimming pools, fighting clubs, shooting ranges, sword dojos and other facilities; The rest area is divided into rest and dining areas, artificial gardens, shopping streets, entertainment centers and other areas; The sleep center is very monotonous, with only rows of sleeping pods, and no one goes up except to sleep.

Chen Xing summoned the robot and began to count the harvest this time and exchange it with the system. Nova's exchange rate is about the same as that of the World Bank, but prices here are much higher.

There were more than 30 kilograms of gold ornaments and bars, which were directly exchanged for more than 5,000 gold coins. There are thirty-seven dark blue pearls, of different sizes and colors, which have been exchanged for more than 30,000 gold coins, and the dragon and snake pair rings have been exchanged for more than 12,000 gold coins. The crystal nucleus can be exchanged directly for gold coins, or turned in to the system, and exchanged for "clearance value" similar to combat exploits.

In the safe station, the clearance value is more useful than gold coins, in addition to exchanging high-level equipment, it can also be used as a mutant creature kill certificate, but it cannot be exchanged for daily supplies. Since the number of crystal nuclei is too small, it can't be exchanged for anything when it is exchanged for clearing value, so Chen Xing keeps it for the time being.

With the original money, Chen Xing now has 48,122 gold, 6 silver and 2 bronze. He directly passed 7,000 gold to the big cat, and asked the other party to buy potions to improve himself.

"Boss, thank you, really, thank you......" probably didn't expect Chen Xing to really fulfill his promise, the big cat was pleasantly surprised, and thanked him vigorously, "You are the best boss I have ever seen, the best and best ......"

"It's a special period, don't send it back, all this money is for you to improve your strength." Chen Xing said with a serious expression. In the last life, the big cat basically never promoted himself, except for the needs of life, most of them were sent back to the house, and he didn't invest much for himself until he died.

But then again, they were so poor in their last life that even if they threw it all on themselves, they wouldn't necessarily be able to improve much. Chen Xing is a lonely person, and it naturally doesn't matter if one person eats enough and the whole family is not hungry. In addition to the old father and mother of Longshi Town, the big cat also has a younger brother, and he can't just take care of himself.

"Even if you want to send it, it can't exceed five hundred."

It is also a bit difficult for a strong man to ask the big cat not to send money back at all, so Chen Xing added. As long as you have the recipient's name and personal number, you can send mail at the security center, but you cannot receive it.

The position of the exile in the Red Earth society is that of an "exiled criminal without rights". Without rights, one cannot be called a "person", so exiles do not even have officially recognized names and individual numbers. Since there is no name and number, there will be no "recipient".

"Okay, I'll listen to you!" The big cat nodded vigorously.

"I suggest that you prioritize increasing your strength to fifty, and then awaken your psionic energy. It's best to have ten points of spiritual power, otherwise it's not enough, and then learn a practical skill. If you still have money left, improve your physique, even if you are agile, it is too cost-effective for you, and it is useless at this stage......"

"Uh-huh, uh-huh."

Chen Xing suggested, and the big cat nodded in agreement while listening. Then the big cat went to work on the upgrade, and Chen Xing also began to make his own plans.

Of the more than 40,000 gold coins, he divided 35,000 to buy potions and improve his attributes. In the Black Death Continent, the more money you have, the more unsafe it is, and it is better to turn it all into combat power. Not only can it reduce snooping, but it can also increase the survival rate, so why not?

It's the same with equipment, an ordinary person with a few thousand gold coins of equipment, or an elite-level warrior with tens of thousands of gold coins of equipment, is almost tempting others to rob it.

Therefore, whether it is money or equipment, the premise of everything is that you have enough strength.

Of the remaining more than 6,000 gold coins, 3,000 were used to buy equipment, and the rest were reserved for mobility.

After making the distribution, Chen Xing immediately went to the pharmacy on the commercial street to buy the medicine. The waiters on the counter are all mechanical dolls in the appearance of young women, very realistic, with delicate and smooth skin and watery eyes, just like real people, or even more beautiful than real people. There are not a few exiles who are killed on the spot due to excessive hunger and thirst and molesting dolls.

Fortunately, Chen Xing is well-informed, all kinds of royal sister goddesses, young girls, and childlike breasts, even king-level ones have enjoyed them, and he just glanced at these puppets a few more times, then withdrew his gaze and put it on the medicine.

In order to improve his survival rate, he decided to increase his agility to 60 points or more. To do this, he purchased a large number of mid-level agility potions. Then there is the spiritual power, after the last breakthrough, he did not rush to improve, and let the realm stabilize first. It's almost time now, to increase the spiritual power to 30 points and enter the next bottleneck period.

Depending on the talent, the bottleneck period is different for everyone. Chen Xing's is similar to ordinary people, and he will enter the bottleneck period every 15 o'clock or so, that is, 15, 30, 45, 60, 75......

This phenomenon is known as the "bottleneck cycle". Some talents are better, such as Yeyang Bailiu, and the bottleneck cycle is about 22 points. The benefits are obvious, in the same state, Chen Xing's 46 points of spiritual power need to break through three times, while Yeyang Bailiu only needs to break through twice.

And after the fifth time, it is already difficult to break through by relying on elixirs, and a higher level of comprehension is required.

Because at this time, human beings have reached the limit of their own abilities and can no longer make breakthroughs. It can only guide the spiritual power of heaven and earth, or the more vast and powerful void spiritual power, to impact the spirit pool wall, so as to break the shackles and step into a new realm.

In addition to the realm manifestation, another sign of the lord level is to communicate with the underground spiritual veins and draw energy from the inner core of the planet. And one of the hallmarks of the king level is to draw energy directly from the void through the spatial barrier.

Back then, Alia used the huge spiritual energy contained in the dark demon crystal nucleus to forcibly break through the spatial barrier, push her personal realm to border the void, and then use the fire demon's natural affinity for the void spiritual energy to guide the torrent of spiritual energy, break through the shackles, and become a legend.

As far as human beings know, there are ten bottlenecks of spiritual power, commonly known as "five-three-one-one".

"Five" refers to the first five bottlenecks. At this stage, there is no leap forward in spiritual power, it is all step-by-step, layer by layer. Since the "amount" of each ascension is fixed, the Neo-Zen Buddhism of the Eastern Continent calls it "building a tower". It means that it is like building a tower, layer by layer.

"Three" refers to the three bottlenecks of the quasi-lord level, the lord level, and the great lord level. Only by breaking through the first five layers can you have the opportunity to perceive the spiritual veins and absorb the energy of the earth's core. This stage is called "stealing fire" by the Church of Light in the Western Continent, which means stealing the fire of the gods and bringing it back to the world.

Every time there is a breakthrough in the Fire Stealing Period, the spiritual power will be doubled on the original basis, which is also called the "Doubling Period".

The remaining two "ones" represent the bottlenecks of the small king-level and the king-level, which are called "whale swallowing" and "celestial combination" by the supreme god cult in the central wilderness, which should literally swallow the energy of the void like a whale, and finally merge with the void to form an independent universe.

People combined the understanding of the three major sects and divided them into the five-layer period of tower building, the threefold period of fire theft, the whale swallowing period and the conjunction.

However, these are far away from Chen Xing, and now he is still in the first layer of the tower building stage, and the goal is to increase his spiritual power to 30 points, and then find an opportunity to break through.

Strength and physique aside, it's not his area of expertise anyway.

Wait for the spiritual power to improve, and then learn a "spiritual compression".

Psionic compression is to compress the psionic energy in the body before using the skill, and then output it. The recharge time is greatly increased, but the condition that could only hold one unit of psionic energy will become multiple when compressed, increasing the power.

Psionic compression at lv1 infuses twice as much psionic energy to the weight of a bullet, but the charging time is quadrupled, or more.

With enough time and a trio, he can shoot six times as much power. And as the level of Psionic Compression and Charged Shot increases, the power will become considerable. It is estimated that even a strong man at the town guard level will be difficult to resist.

The next step is to buy medicine, apply medicine, absorb, check, and so on.

Essentially, all supernatural abilities come from the species' use of psionic energy, and the same is true of the principle of injecting boosting potions to increase attributes.

The Fourth Sage, Luo Ning, once said that the evolution of human beings begins with psionic energy.

Psionic energy is a special kind of biological energy, which exists in large quantities in the void and is the energy produced by living beings from birth to death. They are arranged and combined according to the "life mark" of the species until the mark dies out and becomes a pure energy body.

There are some similarities between the imprint of life and DNA.

As we all know, DNA is the genetic code that records the body structure of living things. It is according to the huge amount of information in DNA that cells are arranged and combined, and the division of labor and cooperation form life.

And the imprint of life is the DNA of the spirit.

Pure psionic energy is a free state of energy, and only when it is arranged and combined through the imprint of life can it form an independent individual.

Therefore, the definition of a spirit is "an aggregate of psionic energy imprinted with the mark of life."

Due to the short time of exposure to high-density psionic energy, the imprint of human life is still very weak. At this time, the spiritual energy in the mutated creature's body is extracted, and its life mark is shattered and injected into the human body. Humans will be able to absorb the life mark fragments of mutated creatures while absorbing psionic energy, so as to strengthen their life mark.

This process is called "attribute enhancement".

So, why does the Broken Life Mark strengthen the stats?

To illustrate this problem, we must begin with the use of psionic powers.

There are two types of psionic use: "active use" and "passive use". In the vast majority of cases, it is used passively.

Even if it is used actively, it is on the basis of passive use. The reason is simple, for example, in automatic firearms, pulling the trigger is an active act, and a series of chain reactions that follow, such as the bolt hitting the primer, the bullet ejecting, the cartridge case bounce off, and the next bullet being pushed into the chamber by the reaction force, are all passive.

For another example, Chen Xing's trio, in the whole application process, only the excitation process is active. And the operation of psionic energy in the body is completely uncontrolled, just like people cannot control their digestion process, the beating of the heart, the growth of hair, and so on. How exactly the effect of the triple bonus was produced, Chen Xing didn't know anything,

And the life mark of mutated creatures contains a large number of "passive application formulas". After human beings absorb it, they can strengthen their own "passive use" of spiritual energy, which is the principle and process of attribute enhancement.
