"What is it?" Mu Xiao didn't react immediately, only vaguely sensing that there was something in the sea of consciousness, a feeling of déjà vu.

  Mù xiāo lěng jìng xià lái, xiǎng le xiǎng shì fǒu yǔ zì jǐ chóng shēng yǒu guān, xīn zhōng àn dào: "gāi bù huì shì wèi lái zì jǐ hé guò qù zì jǐ chóng shēng, liǎng gè bù tóng shí jiān zhóu de líng hún rónghé, yǐng xiǎng le nǎo dì zhōng de yì shi hǎi, dǎo zhì xī shòu yuán quán de shí hou, yì shi hǎi chū xiàn le yī zhǒng sì shì ér fēi de cuò jué?"

  He clearly knew that just now, three intangible auras had merged into his body, and there was a slight cellular joy, but it disappeared instantly. This is the optimization of bloodline genes, but it has nothing to do with the sea of consciousness. Because even if the first evolutionary resonance is produced, it will only be the resonance between the soul and the bloodline, and the sea of consciousness will basically not move. Only those who have reached the evolutionary realm can understand the existence of the sea of consciousness.

  If Mu Xiao hadn't once had a very high and profound cultivation realm, it would be impossible to clearly sense the fluctuations in the sea of consciousness.

  However, by absorbing the intangible energy, there is a term called "Evolution Source" or what can be referred to as "Experience Points", but it's not exclusive to Mu Xi. As long as a New Human kills zombies, mutated monsters, or even their own kind, they will automatically absorb this "Evolution Source" energy essence.

  As for what vaguely appeared in the sea of consciousness, Mu Xiao could only regard it as an illusion.

  In fact, every gene has its value, and any living thing needs to consume energy, so the 'source of evolution' is to enhance personal genes and optimize the pure energy of blood.

  As long as you absorb more, your bloodline genes will evolve, which is what's known as - Gene Resonance.

  He had long surpassed the initial stage of genetic resonance and had cultivated an evolving realm, but now he was at the beginning of an era and had to kill enough times to stabilize his entry into the cultivation phase. Evolution wasn't just about relying on external forces to build a solid foundation; only the power cultivated from within oneself was the root of evolution.

  However, Evolution Resonance is a passive upgrade, while Cultivation can actively absorb energy molecules in the air and directly refine them into the energy needed to enhance one's realm.

  Those three zombies just now were at most third-order bloodline resonance, or you could say they were third-level small monsters.

  Mù Xiāo had just become a new human, although his evolution resonance frequency hadn't appeared yet, but his strength was more powerful than many other new humans.

  However, he just killed three zombies and obtained three strands of spiritual energy, which only had a tiny bit of use. He felt that wanting to quickly increase his resonance frequency was not generally difficult, perhaps because he took the Miracle Medicine, his bloodline and agility made it harder for him to resonate than ordinary people, requiring more 'Evolution Source Springs' to trigger resonance.

  The stronger a living being is, the more perfect and powerful its bloodline genes are, and the richer the 'source of evolution' contained in its body.

  Apart from the Evolution Source, there is another smaller source called Ability Source.

  "Source of Ability" is determined by the training direction of "Genri Bujutsu" and "Soul Secret Art".

  "Ability Source" will appear on the original host, with a relatively low probability of occurrence, unless one of the original ability holder's abilities is particularly powerful, in which case an "Ability Source" will be generated.

  The source of ability must be actively absorbed, if the absorption is successful, there will be a chance to integrate the opponent's ability. If not absorbed, it will disappear in about half an hour. Spatial devices can store the source of ability, but spatial devices on Earth are extremely rare.

  If multiple absorptions of the same attribute ability source are made, one's own ability can be quickly enhanced. The source is determined by the ability holder's original ability size before birth, but reckless absorption will result in death. Moreover, each time an absorption of the same rank source is made, the enhancement gradually decreases. To enhance quickly, it is necessary to defeat and kill a more powerful being than oneself.

  However, the source of ability has different forms. If the form is unclear, it is equivalent to not being able to distinguish what kind of ability it is. It's okay if useless abilities are absorbed, but if an ability that conflicts with one's own ability is absorbed, there may be unpredictable dangers.

  The bloodline of Earthlings has a compatible property, when the bloodline condenses into energy and is cultivated to perfection, all abilities will be fixed. To develop new abilities, a greater price must be paid, and the more abilities contained in the bloodline, the slower the improvement, even unable to break through the constraints. However, each ability is well-compatible with each other, has a mutual complementary effect, can turn disadvantages into advantages, and accelerate cultivation.

  If the source of evolution is experience points, anyone can refine it. The source of ability is a good thing that increases skills and proficiency.

  As a new human, not only do you have to contend with the enemies of biochemical monsters, but also face dangers from other new humans. Because some new humans are identical or beneficial to their own cultivation, many people will resort to killing each other to enhance their own strength, resulting in many new humans not trusting others in the later stages.

  Mushishi was originally a cold and unfeeling person, he had always been accustomed to acting alone. Having grown used to the new humans' self-destructive tendencies, he had also killed some of his ill-intentioned companions, absorbing their "Evolutionary Source" and "Ability Source". The open and secret struggles for power among various forces were too numerous to count.

  However, the acquisition and absorption of any ability requires a certain physical and bloodline foundation. For example, Mu Xi's SSS-level physique seems very strong, but it was only strong in the former Federation system. If he were to evolve into a new human, it would be different. For instance, why can't he exert his willpower? It's because his physique is not strong enough, his bloodline optimization degree is not high enough, which means that the number of times he has evolved and resonated is not enough, and his realm is not high enough.

  Although the ability to absorb the source of power can be accelerated, it often fails to reach the level of blood and flesh, unable to withstand a larger source of power. It's like a container that must be tempered with physical exercise, as well as consuming rich energy meat, nutrient liquids, life gene medicine water, etc., trying every means to increase the strength of blood and flesh, only then can it advance to become even stronger.

  In order to strengthen the body and enhance the power of heterosis, there are some condensed substances on the zombies and mutant monsters that are very useful for new humans, and even old humans can evolve into new humans.

  This is also the post-era, old humans are desperately trying to make a living, evolving into new humans' objects of hope.

  ……

  Mushuo didn't delve deeper into the strange substance that appeared in the sea of consciousness, mistaking it for an illusion, and continued with his own affairs.

  "Three zombies only have the power source of evolution, no ability source burst. It's true that it's still in the first stage now, and this thing called ability source is quite rare." Mu Xiao was used to thinking in the way of the future era, unknowingly searching for a familiar feeling within himself, so as to get accustomed to the stormy weather after rebirth.

  The zombies in the early stages can only be considered a low-level variant monster, and after experiencing slaughter, Mu Xiao killed them without any unnaturalness. Instead, she found a sharp but energy-less military knife and quickly searched for something on the bodies of three zombies.

  Soon, Mu Xiao found a brown condensate the size of a soybean in the heart area of three zombies, which was very useful for new humans and what old humans wanted to evolve into.

  However, these brown condensates are only the lowest level of substance, with a slight enhancement effect on the physical body, followed by a therapeutic effect, but only for the physical body, and have no therapeutic effect on spiritual consumption and spiritual trauma.

  "As expected, it's not easy to get things in the early stages. Take Blood Beads for example, a common item, but compared to the later stages of the Evolution Era, the quantity and quality of drops are worlds apart." Mu Xiao muttered to herself as she put away six of the lowest-quality Blood Beads.

  Blood pearls are the universal currency of the post-apocalyptic world. Most zombies, mutants, and mutated beasts have a blood pearl congealed in their heart, which varies in size from a small pea to a large bean. The quality of the blood pearls is divided into: inferior (brown-red), ordinary (vermilion), high-quality (deep red), and rare (purple-red).

  The blood bead Mu Shao just obtained is of the lowest grade and of poor quality.

  Apart from blood clots, there are also blood crystals and crystal nuclei.

  Apart from the Lich, other powerful mutant monsters' hearts will condense into Blood Crystals to strengthen their bodies, but it is extremely rare and more valuable than Blood Pearls. This is the concentrated essence of the mutant monster's blood, condensed in the heart, which is pure blood without any viruses.

  However, if too much is taken at once and not immediately refined into the body, there will still be adverse reactions. It is very likely that the violent consciousness in the blood crystals will affect one's intelligence and character, leading to errors in evolution, also known as going crazy from excessive energy, becoming a mutant.

  The quality classification of blood crystal and blood bead are the same.

  As for Crystal Nucleus, it is the most valuable material and can only be obtained from high-level variant monsters.

  This is a pure energy thing condensed by spiritual power, wrapped in bone membrane and formed in the brain. Its functions include increasing ability effect power, enhancing spiritual power, repairing spiritual trauma, activating hidden potential of the brain, and many other benefits. The quality is divided into: silver (mercury-like liquid), pure white (with flowing light lines, jelly-like body), transparent crystal (crystalline).

  However, Mu Xiao estimated that there are currently almost no variants of people who can condense high-concentration substances.

  Because the airtight room no longer had any biohazardous monsters that could threaten him, he directly dragged the three corpses out of the room. The foul odor released from the dead zombies would only grow stronger and soon attract other zombies to come and devour their own kind's corpses, undergoing self-evolution.

  The secret room was rid of the annoying thing, Mu Xiao directly closed the door of the secret room, but due to the electronic lock being broken, he could only use a padlock to manually lock the door.

  Many machines were out of order, and Mu Xiao directly found a number of B-grade or lower weapons from those safes. Among them was an A-grade Thunderfire Cannon, which, together with the one on his back, made three cannons in total. However, for now, he couldn't use too many weapons, so Mu Xiao took two B-grade ray guns and changed into a set of 'Black Armor' defensive suits.

  These are defensive uniforms with three layers of soft steel inlaid, having a certain defense power, a kind of E-level defense equipment, also known as whiteboard equipment.

  But the black armor has a certain defensive power, which is much stronger than ordinary clothes. So, Mu Xiao changed into this set of defensive clothing on the spot without hesitation.

  Next, he found small amounts of weapons in other metal lockers, as well as some federal credit notes, but now the credits and credit points were useless things, even a fruit knife was more valuable than a large pile of meaningless numbers.

  Mushan found a large amount of dried meat, high-fat butter, bread and other food in some guarded personal drawers. Moreover, he also found five nutrient solutions, three ordinary ones, two intermediate ones, which was already a pretty good harvest, after all, Mushan was just hungry.

  "Defending welfare is pretty good, and there's even a supply of nutrient solution." Mu Xiao's mouth was stuffed with greasy food, ignoring the bloodstains on the ground and around him as he continued to rummage through the secret room.

  He finally found twenty or thirty C-grade high-explosive grenades in a small metal cabinet.

  To know now, any weapon is temporarily unusable, but hand grenades are different, basically no problem at all.

  This is now the best lethal force weapon available.

  Musha's mood was great, he found a large backpack and packed all the hand grenades and food, a sharp military knife, along with two ray guns, then put them on his back together with the rocket artillery. He didn't plan to move other weapons, nor could he carry them all, so he had to leave them here for now and move his nest here as soon as he returned.

  He drank all the nutrient solution and ate more than half of the food, replenishing his semi-full state. He was ready to find another hidden chamber.

  Just as he walked to the door, there was a rustling sound outside. He extended his spiritual power three meters out to detect and found that three or four zombies were crouching down to devour the corpses of the two zombies from earlier.

  Mù Xiāo once again picked up the electric baton that could be used as an iron rod, quickly opened the door, and with a swift and fierce movement, smashed the heads of two zombies, while the other two zombies were in Mu Xiao's blind spot, the electric baton struck continuously, unable to get past them, allowing the two zombies to regain their reaction ability.

  Two stinky zombies with their mouths wide open pounced over, if it were an ordinary person, they would have screamed in fright. But Mu Xiao reacted extremely quickly and kicked one of the zombies' faces, her leg strength was like steel, kicking it into disfigurement, its entire face caved in, the back of its head exploded. The other zombie was also punched by Mu Xiao in the center of its chest, the impact force shattered the zombie's heart.

  The fatal point was hit and two zombies died quickly.

  The four intangible essences merged into Mu Shao's body once again, but this time they failed to calm him down. Instead, the thing in his consciousness resurfaced, clearer than before, and it seemed to have grown significantly larger.
