The Sea of Consciousness has surfaced a strange energy substance twice in a row, and Mu Xiao vaguely feels that this is not an illusion created by himself.

  "Could it be that my soul has merged with a future soul, producing an unknown energy that only appears when I increase my strength?" Mu Xiao adopted a trying attitude and sank into the quiet of his cultivation state with great familiarity. The weak thoughts that had not been cultivated yet scooped up the consciousness sea, searching for the strange substance that had disappeared.

  In an instant, a very clear consciousness fed back.

  "Really?" Mu Xiao was taken aback, but soon became excited, "It's actually an even more refined and original source of energy, this can be used to enhance innate abilities!"

  The evolution of the new human being relies on the PB virus, or the original energy of the PB medicine, which is the catalyst for the greatest genetic change in the new human being. In other words, there is a kind of "energy substance" in the air that changes the genes of the new human being, just like the "spiritual energy" in the cultivation of immortals.

  However, the original energy is also known as the original source, but it's just that the "original" substance in the air is too difficult to purify. After all, the entire world has undergone viral mutations, and the original source substances have all changed. Only those people on the moon retained a part of the original source, which is why in the future days, the moon will still have countless highly gifted new human warriors, and this is precisely the reason.

  Now that Mu Xiao can absorb this kind of primitive source on his own, he can naturally optimize his potential and has a high probability of accelerating his future cultivation.

  "It was probably after my rebirth that my soul, which had already cultivated a high-level realm, emitted vast energy and influenced the sea of consciousness, causing mysterious changes. Perhaps there was also a connection with the Miracle Bloodline Formula, triggering all these changes, and only then did some refined essence from the source merge into my sea of consciousness. If the original energy substance wasn't useful, why would those pseudo-gods in 'Divine Revelation' who claim to be gods go to great lengths to conduct genetic research..."

  Mu Xiao thought for a moment and believed that this was the most likely mutation of his soul's rebirth, but it was a good thing, and also increased his potential.

  He turned his mind back to the surface of the sea of consciousness, and led those scattered original sources into the soul and body, so that both "Source Power Martial Arts" and "Soul Secret Method" can reach the super strong innate potential.

  He originally had the power of yuan and spiritual energy, and now he has acquired a new kind of primitive source that can strengthen his soul and body. With this, he will have no problem cultivating any technique, and he will be able to fully exert the ultimate power of "Yuanli Wuxue" and "Linghun Secret Method", without worrying about insufficient innate talent or weakened power.

  "The soul may have changed, but the absorption is not obvious. Instead, the physical body has become more prominent. Now is not the time to cultivate the soul, but rather the physical body is more beneficial for current battles." Mu Xiao thought carefully based on his own situation and decided that next time he would focus mainly on strengthening his physical body at the original source spring.

  In short, a bit of strength is still strength. He restrained his emotions and dug out nine poor-quality brown blood beads from the four zombies that had just died.

  "Although the quality of the blood beads is a bit poor, mosquitoes are still flesh and blood after all. Moreover, some medicines also require a large number of blood beads as materials." Mu Xiao put the blood beads in the same small cloth bag, then picked up the metal rod electric shock stick and walked down the stairs below.

  The fifth floor has only one secret room, basically every floor has a secret room. Mu Xiao walked down this not wide or narrow staircase, which is the internal passage hidden in the lawyer's building, and can go directly to the underground or other floors' secret rooms.

  Four more zombies died upstairs, and the stench they emitted quickly spread throughout the stairs. Suddenly, the sound of a push-pull door creaked, and footsteps with greater strength than ordinary people appeared, echoing clearly in the dark and silent stairwell devoid of any living person, filled with an eerie horror.

  "I don't know how many zombies are hiding in the lawyer's building, and I don't know if there are any more mutated people left here." Mu Xiao frowned, wanting to eliminate all the unstable factors in the building at once and take over the lawyer's building smoothly, but it was obviously not an easy task.

  If there were hot weapons in hand, Mu Xiao wouldn't have such a hard time, although with his SSS-level physique he basically didn't fear zombies, but the progress of killing zombies was undoubtedly much slower. Of course, using grenades would also work, but this would easily damage the floor structure, and he didn't want his base to be broken and messy.

  "It seems that we can only use the 'guarding the tree and waiting for the rabbit' method." Mu Xiao stopped on the fourth floor staircase, preparing to utilize the zombies' desire to devour their companions' corpses to lure all the zombies in the building over. After all, the mutated humans were not interested in the smelly zombie flesh, so it was unlikely that they would be attracted over, unless the mutated humans had a craving for Mu Xiao's fresh flesh and blood, which would attract them over.

  Mushan put down the backpack on his body, holding a military knife in his left hand and a metal electric baton in his right hand, guarding the entrance of the fourth floor. His spiritual power extended about 7-8 meters, and as long as any living thing entered this range, he could roughly detect the strength or weakness of the creature's vitality, and also sense the degree of danger.

  He actually had a good way to kill monsters using his mental power, but he didn't want to consume too much of himself. After all, he had seen the birth of mutants with his own eyes and was naturally extremely vigilant. If he really encountered a mutant and his body consumed too much, he would fall into crisis. Moreover, his current strength was enough to deal with zombies, so it was best not to use his trump card unless necessary. In this world full of monsters, every bit of energy couldn't be wasted, and not leaving any spare energy was an extremely dangerous thing.

  A hoarse and dry crackling gasp and a solid footstep, entered into the spiritual exploration of Mu Xiao.

  "One, two, three... In the past, I could take down hundreds of these small things with just one palm strike, but now it's like playing a game, re-leveling up without any skill involved, how boring!"

  He muttered to himself, but in fact he was very clear-minded. Even if it was 're-leveling', there was only one chance, and once dead, he would really die, so no matter how boring it was now, he was extremely vigilant against all dangers.

  At this time, a large number of zombies rushed in, among which one zombie had muscles that were more developed than the other zombies, with ten times the evolutionary degree of gene resonance, and its physical strength was extremely close to S-level physique. This is the strongest one among more than ten zombies, and it is very likely to recover its sanity and evolve into a variant human existence over time.

  Mu Xiao let out a deep breath, his expression fully entering combat mode.

  The first zombie entered his attack range, and with a swift and fierce slash of his hand, a dark shadowy knife mark appeared, brutally cutting off the zombie's neck. The entire head was severed in an instant, and with a sudden burst of wind, it shot out like a ball, kicking away. The zombie's head exploded like a rotten watermelon, bursting into a shower of small black raindrops.

  Roar!

  The moment Mu Xiao made his move, he lost the effect of odor masking. More than a dozen zombies discovered the fresh flesh and blood smell, like starving wolves and tigers, letting out low growls that made people's hair stand on end. They burst forth with several times their original strength, their eyes gleaming with bloodlust as they clawed and bit.

  Fortunately, the stairwell could only hold three zombies, and the zombies in front blocked most of the zombies behind, so Mu Xiao didn't have to face the crazy attack of more than a dozen zombies at the same time.

  Metal rods rained down densely, exploding the heads of three zombies in front one by one. As each zombie fell, more behind them charged forward desperately. Mu Xiao took advantage of her SSS-level physique and used the most concise yet brutal method to smash the brains of the zombies into mush.

  The zombie's face was twisted and distorted, its body bursting into a bloody mess with a loud crash. Mu Xiao thrust the blade of her knife into the forehead of another zombie, using a clean and efficient motion to twist it, and at the same time kicked out at the zombie's chest, causing its bones to shatter with a crunching sound. The zombie's body was sent flying back like a sandbag, colliding with another zombie behind it and slowing down the ferocity of their charge.

  With a loud whooshing sound, hands and feet moved in unison, opening and closing in a big way to meet the zombies' attack.

  Not a single zombie can withstand Mu Xiao's one-hit attack, after all, an SSS-level physique is far from comparable to dozens of A-level physiques. Moreover, zombies only have instinctual attacks, without any tactics or coordination, and do not understand defense or evasion, they are just targets.

  Suddenly, a fist broke through the air and heavily struck Mu Shao's head.

  Mù xiāo had long noticed this tenth-level evolved muscular zombie, and with a slight adjustment of the military knife in his hand, he stabbed at the iron-like fist with a sharp and vicious blade.

  The flesh and blood body can't withstand the sharpness of the knife, plus the heavy impact force under one punch, the blade directly enters the zombie's fist, but the zombie doesn't know the pain, the fist strength is just a pause, seemingly coming fiercely to Mu Xiao, in fact, the fist wind has weakened a lot.

  The moment Mu Xiao stabbed the military knife in, he immediately withdrew his hand and retreated, not intending to harden the muscular zombie's heavy punch.

  He also knew that zombies didn't have pain nerves, but that didn't mean the knife edge stabbing into the zombie's fist wouldn't affect its state. After all, the blade was inserted into the muscle of the fist, to a large extent blocking the output of strength. The human body is like a machine, if the machine is stuck by something, then the output will not be as smooth as before.

  Taking advantage of the opportunity, Mu Xiao swung his metal rod in a single motion, striking the muscular zombie's head with a loud crash. However, instead of shattering into pieces as expected, the metal rod merely bent slightly, but Mu Xiao still held it firmly and dodged to the side, avoiding the muscular zombie's heavy punch. He then struck again, blasting the head of another approaching zombie.

  The muscular zombie's double fists brought a bloody storm wheel over, and Mu Xiao's arm suddenly exerted force. The metal rod cut across like a knife, bringing a burst of breaking wind power, heavily striking the zombie's fist. A heavy sound of colliding objects was heard, and the entire metal rod was completely bent and rendered useless. However, the muscular zombie's fist also became a bloody mess, with black blood flowing out like a small stream.

  Mù Xiāo's eyes gleamed with a cold light, and he continuously retreated several steps, dodging the muscular zombie's punching fist. At the same time, he used force to smash the scrap metal rod onto the back of another zombie's head. When the muscular zombie's fist lost its momentum, Mù Xiāo took a step forward, swiftly grasping the knife edge on the zombie's fist like lightning. He pulled it out and took another step forward, reversing his grip on the military knife, and with a swift and deadly motion, stabbed the muscular zombie in the temple and then strangled it.

  Physically strong, but there are still some parts of the body that are fatal weaknesses.

  New humans are like this, zombies are also like this.

  The muscular zombie's head had been severely damaged, its strength greatly diminished. After Mu Xiao added a few more slashes, this tenth-order genetically resonant muscular zombie also fell in the stairwell. The remaining two or three zombies were quickly beheaded by Mu Xiao, their heads exploding one after another.
