Strange energy substances appeared in the sea of consciousness twice in a row, and Mu Xiao vaguely felt that this was not an illusion formed by himself.

"Could it be that my soul has fused with the soul of the future, producing an unknown energy that will only appear when I increase my strength?" Mu Xiao held a tentative attitude, sinking into the tranquility of the cultivation state very familiarly, and the faint thoughts that had not been cultivated salvaged to the sea of consciousness, looking for the strange substance that had disappeared.

The moment his thoughts went to the sea of consciousness, soon a consciousness was very clearly fed back.

"Isn't it?" Mu Xiao was stunned for a moment, and soon his heart moved, "It's actually a more refined source of primordial energy, this is a source that can be used to strengthen the potential of talent!" ”

The evolution of new humans relies on the PB virus, or the original energy of PB medicine, which is the introduction of the biggest genetic change of new humans.

However, the primordial energy is also known as the primordial source, but the "primordial" substances in the air are too difficult to purify, after all, the entire world has undergone virus mutations, and all these substances of the primordial source have changed, and only those on the moon have retained a part of the primordial source, which is also for the future days, the moon still has countless new human warriors with extremely high talents, and this is precisely the reason.

Now that Mu Xiao can absorb this primordial source on his own, he can naturally optimize his potential even more, and there is a great chance to speed up his cultivation in the future.

"Probably after being reborn, my soul who has cultivated the high and profound realm exuded a huge amount of energy, affecting the sea of consciousness and undergoing mysterious changes, perhaps there is also a relationship between the miracle bloodline formula, which triggered all the changes, and only then did I integrate some purified essence sources into my sea of consciousness. If the primordial energy matter is useless, how can the pseudo-gods in the "oracle" who claim to be "gods" go to the trouble of doing genetic research......

Mu Xiao thought about it for a while, thinking that this was the most likely mutation of his soul rebirth, but this was a good thing, and it was also a foundation to increase his potential.

His mind turned back to the sea of consciousness, and introduced those scattered primordial springs, some into the soul and some into the body, so that both the "Source Force Martial Arts" and the "Soul Secret Method" could achieve the super talent potential.

Originally, he already had the source power and spiritual power, and he cultivated a method of "Mind Divine Power" that combined martial arts and secret methods, and now there is a primordial source that can strengthen the soul and body, so it will not be a problem for him to cultivate anything in the future, and he will be able to exert the "Source Force Martial Arts" and "Soul Secret Method" to the strongest power, and there will be no lack of talent and weakened power.

"The soul may have changed, the absorption doesn't seem to be obvious, but the physique is more obvious, now is not the time to cultivate the soul, but the physique is much more beneficial to the current battle." Mu Xiao thought about it carefully according to his own situation, and planned to focus on the next primordial source mainly on physical strengthening.

In short, one more point of strength is strength, he restrained his emotions, and dug out nine brown blood beads of the worst quality from the four zombies that died just now.

"Although the quality of blood beads is a little worse, no matter how small the mosquito is, it is still meat, not to mention that some medicines also require a large number of blood beads to make materials." Mu Xiao put the blood beads in the same small cloth bag, then picked up the electric shock rod of the metal stick and walked down the stairs below.

There is only one secret room on the fifth floor, and there is one secret room on the basic first floor. Mu Xiao walked down this staircase, which was not wide or narrow, which was the internal passage hidden in the lawyer's office, which could lead directly to the underground or to the secret rooms on other floors.

Four more zombies died upstairs, and the stench emitted soon filled the entire staircase. Suddenly, the sound of squeaky sliding doors, the sound of footsteps more powerful than ordinary people, echoed coldly and clearly in the dead and gray stairwell without any living people, full of horror.

"I don't know how many zombies are hidden in the Lu Dao Law Firm, and I don't know if there are any mutants left here in Lu Dao." Mu Xiao frowned, he really wanted to stifle the uneasiness in the building once and take over the lawyer's office smoothly, but it was obviously not an easy task.

If there is a hot weapon in hand, Mu Xiao is not so difficult to commit, although he is basically not afraid of zombies with his SSS-level physique, but the progress of killing zombies is undoubtedly much slower. Of course, he could use grenades, but it would be easy to destroy the floor structure, and he didn't want his base to be in tatters.

"I can only wait for the rabbit." Mu Xiao stopped in the stairwell on the fourth floor, ready to use the zombies' desire to devour the corpses of his companions to attract all the zombies in the building, after all, mutants are not interested in stinky zombie meat, and it is unlikely to attract them, unless mutants have a desire for Mu Xiao's fresh flesh and blood, they will be attracted to it.

Mu Xiao put down the backpack on his body, held the saber in his left hand, and the metal shock rod in his right hand, guarding the checkpoint on the fourth floor, his spiritual power extended for seven or eight meters, as long as he entered this range of creatures, he could probably detect the strength of the creatures, and he could also sense the degree of danger.

In fact, he has a good way, which is to use his mental power to kill monsters, but he doesn't want to consume too much, after all, he has seen the birth of mutants with his own eyes, and his heart is naturally vigilant. Besides, he now has more than enough strength to deal with zombies, and he can't use the killer weapon as much as possible, in this world full of monsters, every ounce of strength can't be wasted, and it's very dangerous to spare no effort.

The hoarse and dry cracking gasps and the sound of steady footsteps entered Mu Xiao's spiritual exploration.

"One, two, three...... In the past, I used to have hundreds of these little things in one palm, but now it's like playing a game, releveling without any technical content, it's really boring! ”

Mu Xiao nagged to himself, in fact, he knew very well in his heart that even if he 're-leveled', there was only one chance, and once he died, he would really die, so no matter how boring he was now, he was also very vigilant against all dangers.

At this time, a large number of zombies poured in, among which one zombie has more developed muscles than other zombies, with ten evolutionary genetic resonances, and the physical strength is very close to the S-level physique, which is the strongest one among the more than ten zombies, and it is very likely that it will recover its sanity and evolve into a mutant in time.

Mu Xiao exhaled a breath in his heart, and his demeanor completely entered a combat state.

The first zombie entered his attack range, and a shadow knife mark was quickly brought up in his hand, and the zombie's neck was cut off fiercely, and the whole head was cut off in an instant, and suddenly the wind was under his feet, and he hit a volley, kicking it like a ball, and the zombie's head was like a rotten watermelon, bursting into a small black rain.

Roar!

The moment Mu Xiao made a move, he lost the smell shielding effect, and more than a dozen zombies found the smell of fresh flesh and blood, and let out a low roar like a jackal hungry tiger, bursting out with strength that was originally five or six times faster, and his eyes were bloodthirsty to bite and pounce.

Fortunately, the stairwell can only accommodate three zombies, and the zombies in front block most of the zombies in the rear, so Mu Xiao will not face the crazy attacks of more than ten zombies at the first time.

The metal shock rod fell tightly like raindrops, and the heads of the three zombies in front exploded one by one, and every time the zombies in front fell, the zombies behind rushed desperately. Mu Xiaomian used his SSS-level physique advantage to knock the heads of zombies into pieces with the most concise and brutal attack methods.

The zombie's hideous, twisted face shattered into a blur of flesh with a low thud. Mu Xiao stabbed the blade into the eyebrows of the other zombie, twisted it cleanly, and kicked the zombie's chest by the way, cracking his bones, and the zombie's body was kicked back like a sandbag, and the impact force knocked a zombie in the back squarely, easing the fierce impact of the zombie forward.

Mu Xiao used both hands and feet, opening and closing to meet the attack of zombies.

No zombie can resist the power of Mu Xiao's blow, after all, an SSS-level physique is far from being comparable to dozens of A-level physiques. What's more, zombies only have instinctive attacks, without any rules and cooperation, and they don't know how to defend and dodge, just like targets.

Suddenly, a punch broke through the wind, and it hit Mu Xiao's head fiercely.

Mu Xiao had long noticed this tenth-level evolution muscular zombie, and slightly adjusted the angle of the saber in his hand, like the tip of a shuttle knife, and stabbed it with a sharp blade very viciously and stabbed at a fist like a hammer.

How can the flesh and blood body block the sharpness of the tip of the knife, coupled with the heavy blow power under the punch, the blade directly sank into the zombie's fist, but the zombie didn't know the pain of the road, the fist strength was just slow, and it seemed to be bombarding Mu Xiao unabated, and the actual fist style was much weaker.

The moment Mu Xiao stabbed the saber in, he immediately withdrew his hand, not intending to take the power of the heavy punch of the muscular zombie.

He also knew that zombies did not have pain nerves, but it did not mean that the blade stabbed in the zombie's fist did not affect the state of the zombie, after all, the blade was inserted into the fist muscle, which largely prevented the output of strength. The human body is like a machine, and if the machine is stuck with something, the output must not be as smooth as before.

Taking advantage of this opportunity, Mu Xiao unchangeably pulled off the head of the muscle zombie, and trembled suddenly, not as expected, but the metal rod bent slightly, but Mu Xiao still held the metal rod steadily, dodged the heavy punch of the muscle zombie sideways, and blew up the head of the zombie next to him with another stick.

The muscular zombie's fists brought up the bloody wind wheel, Mu Xiao's arm suddenly exerted force, and the metal rod slashed sideways like a knife, carrying a burst of wind-breaking force, and hit the zombie's fist hard, with a heavy hard object collision, the entire metal rod was completely bent and scrapped, but the fist of the muscular zombie also became bloody and blurred, and black blood flowed out like a stream.

Mu Xiao's eyes bloomed with cold light, and he took a few steps back in a row, dodging the fist from the muscle zombie, and at the same time smashed the scrapped metal rod to the head of a zombie in the back, when the muscle zombie fist lost its follow-up strength, Mu Xiao stepped forward, held the blade on the muscle zombie's fist as fast as lightning, pulled out, and went further, clenched the saber with his backhand, and stabbed and twisted it neatly and sharply into the temple of the muscle zombie.

The physique is strong, but there are still some parts of the body that are fatal points.

This is true of the new humans, and so are the zombies.

The head of the muscle zombie has been hit hard, and the strength has been greatly lost, after Mu Xiao made up for it a few times, the muscle zombie with ten genetic resonances also fell in the stairwell, and the remaining two or three zombies were quickly cut off by Mu Xiao and kicked them one by one.
