The entire lawyer's building was dead silent, with only a non-human hoarse voice, like a needle piercing, making people's skin crawl with a sense of horror. Every floor had lost all signs of life and vitality, the air was filled with a pungent smell of blood, like a rotting corpse, casting a dark and eerie shadow over the already gloomy environment, making it hard to breathe.

  Muxiao barely combined his innate abilities with the power of "Intentional Divine Force", although he didn't truly cultivate it, but its characteristics were brought out and enhanced his spiritual power's sensitivity. Even if he didn't release his spiritual power externally, he could still sense whether there was any danger within a 10-meter radius around him. If he did release his spiritual power externally, he could get more accurate information about the surroundings. However, releasing his spiritual power also had a side effect of draining his physical strength at an alarming rate, as if expanding his Intentional Divine Force would make his body feel hungrier and hungrier, giving rise to an intense desire to devour even his own flesh and blood, filling him with an eerie feeling.

  "Undead seem to have this endless devouring desire, I wonder if there's something wrong with my own body?" Mu Xiao tried several times to test the effect of his mental power, and his heart was filled with a chill.

  After all, "Intentional Divine Power" he himself had never cultivated, only knew the cultivation process, and naturally had no bottom in his heart.

  However, Mu Xiao found that his consciousness seemed to be unaffected by negative emotions and temporarily put aside his worries, thinking that he was just not strong enough to withstand the normal release of spiritual power. Moreover, he had not eaten anything for three days, and after a series of strengthening exercises, his body's consumption was still quite high.

  "Mind power cannot be used excessively, otherwise it is possible to drain one's own body." Mu Xiao still warned himself.

  He knew that the greater the power, the greater the restriction, and exceeding a certain limit, what might collapse was the vessel that bore the power.

  ……

  Mu Xiao tidied up her clothes, put away her light brain chip, and checked the Thunderfire Cannon. She found that it was no longer usable and could only be tied to her back. It would have to wait until she acquired the "Mechanical Control" or "Weapon Mastery" ability to reactivate the weapon.

  The air is already filled with mutated free radicals and electromagnetic fields, which not only change the body's recognition, but also invade energy-containing machinery, and will gradually change plants, resulting in some changes. Among them, 'mechanical grasp' is to repair machinery, accelerate the absorption of mechanical knowledge, and weapon grasp is to master the characteristics of weapons like a native, and become proficient as soon as you pick it up.

  After mastering machinery/weapons, there are also machinery/weapons specialization and control... Each upgrade has different knowledge power, which is the ability of the spiritual intelligence system. If you cultivate the "Soul Secret Method", in an instant, you can control any mechanical recombination, and weapons become a part of your body, like an arm and finger.

  However, the abilities of machinery and weapons were common in the late evolution era of Mu Xi, just like the existence of game identification techniques, activating old antique weapons and fully utilizing them, this is the way for new humans to assist in combat in the future evolution era.

  Now, globally, machines and weapons are gradually malfunctioning, causing many weapons to be unusable, and naturally, large-scale destructive weapons cannot be activated either, unless armed forces are dispatched from the moon. However, the Earth is already filled with strange electromagnetic fields, and those extraterrestrial weapons entering the Earth will also lose their effectiveness in a short period of time.

  So, before long, the earth will become a desperate closed place, unless you grasp the power of knowledge, modify your weapons, make them work normally and enhance their power, so that you can have the basic ability to survive.

  Therefore, mastery of machinery and weapons is a lifesaving ability for people in the early stages. If they can't even use their weapons, their survival abilities will undoubtedly be greatly reduced.

  "In the post-apocalyptic era, too many weapons were buried, perhaps because they were limited by their capabilities. After all, weapons would definitely outlast humans, and only new humans could use them, unless a new human with mechanical expertise came along to modify them for anyone's use...” Mu Xiao thought to herself as she began to clear away the clutter that had been piled up in front of her room door.

  Generally, people who have evolved into new humans will not spend their minds modifying weapons for the use of old humans, because old humans in this era have no status to speak of. Moreover, modifying machinery into ordinary ones would only lower the essence of machinery, and nobody would do something that is not worth the effort.

  However, living in this era still has its benefits. The air on Earth will gradually change, no longer being murky and containing energy. Only those who survive will have their bodies become better and better, perhaps one day naturally becoming a new human, eliminating the distinction between old and new humans.

  Of course, in the early days, for old humans, having a better body was tantamount to being unable to live, and only by evolving into new humans did they have the qualification to survive.

  But power is a corrosive poison that corrupts human nature, the early new humans' evolutionary realm must be several times higher than that of the mid-to-late new humans, so the powerful early new humans like to be high above, under the long-term killing, planting extremely complex emotions in their hearts, among which the desire for power and ambition are the most common emotions.

  Therefore, the new human overlords like to enslave the old humans and have even developed drugs that suppress the old humans' ability to evolve. They can even regress the new humans back into their old human physical form, ensuring that the old humans remain forever in a lowly position as a weak and vulnerable group at the mercy of others.

  Having gone through a long and arduous evolutionary path, Mu Shuo is extremely clear about the cruel human nature of future eras, and also understands that such things are inevitable in the future. However, he does not want to be a savior, nor does he want to believe in anyone or be saved by anyone. He only believes in his own strength, becoming a powerful person who cannot be swayed by anyone, standing at the pinnacle.

  ……

  Muxiao was not prepared to return home quickly, although Muxiang had already been at home alone and might be in great danger. However, he thought that since there were not many people living nearby, as long as his little sister saw the note he left behind, she would definitely survive.

  If Mu Xiao knew that dozens of beauties had already moved into his home, he would quickly return home, not for those beauties, but to "protect" the rare resources that would be developed in the future and prevent them from being wasted by them. Moreover, his resources were worth hundreds of times more than the resources in Warehouse No. 9 owned by Shangguan Xuanhui, after all, every time a period of time passed, resources would become scarcer and eventually disappear, making it difficult to find them. His rare medicines were even more so, and the goods he helped Shangguan Xuanhui purchase were only mid-to-low-end products, and naturally could not be compared with his own resources.

  Of course, some resources in the later period are now unavailable in the early period, so Mu Xiao's knowledge and methods can't be used either, it's a double-edged sword.

  He didn't return quickly because this is a special agency and there are some things he wants to get that he can't let go of.

  Mu Xiao didn't go out to the third floor corridor, but instead wanted to return to the previous secret room and look for other secret places in the entire lawyer building. After all, this is a dark institution of federal agents, and it must store many good things such as weapons and medicines.

  He considered turning the entire lawyer's building into his own secret base.

  "It seems there's a basement here... Hmm, let's sweep the entire upper floor first, then explore downstairs. But for now, let's find a suitable weapon."

  Muxiao's physical strength had reached SSS-level physique, with explosive power exceeding that of any ordinary person. He could tear gold and shatter stone with his bare hands, and an average person couldn't withstand even one of his normal punches. Therefore, previously he had damaged the metal door leading to the dark room, preventing monsters from attacking, and now he could almost directly force it open with brute strength.

  Crack! Snap!

  Metal shattered with a sharp, ear-piercing sound.

  He carefully pulled out a half-body-sized entrance from the damaged metal door, not wanting to make too much noise and attract unknown creatures in the dark room. If he encountered zombies, it would be fine, but if he encountered mutants, he could only use his mental powers to fight back, otherwise it would be difficult for him to gain an advantage over the mutants.

  The silent staircase, no one in sight, nor any bloodstains, the wooden floor creaking as if no one had passed through here.

  "The staircase here can lead directly to the underground, and also to floors one to five. Who knows if some monsters have already come out from other rooms." Mu Xiao went straight up to the fifth floor, where she had once been trapped with Shui Bai Lan in a secret room. There was an evolved mutant human there, which Mu Xiao had seen with her own eyes. If they encountered it, it would be better to kill it as soon as possible, otherwise, if the mutant human evolved and gained special abilities, it would be a big trouble.

  New humans have innate abilities, and mutants also have abilities.

  However, the new human can obtain the source of power from the variant or zombie, enhance the evolution degree of bloodline, that is, genetic optimization. There is also a certain probability to acquire other abilities, namely physical system, spiritual system, transformation system, source force system, intelligence system, space system, and mysterious system abilities. These abilities are the greatest foundation for future self-cultivation.

  He went up to the fifth floor, and Mu Xiao finally saw the black bloodstains all over the ground. He slightly measured it with his eyes, and his spiritual power surrounded him within a three-meter range. Any foreign object that entered this range would definitely be detected by him, and even killed with his mental power.

  This was him using his mental powers with the least consumption, and he didn't dare to directly sweep his mental powers across the entire building, or else it would have consumed him to death.

  Returning to the floor of the secret room, Mu Xiao slowed down a few steps and retracted his spiritual power, shielding the fresh flesh aura he emitted. Generally, both Nen and Spirit Energy have shielding abilities, but Intent Spiritual Power is a combination of the two, making its shielding effect even more outstanding.

  It can only be used as a small trick in the early stages, and if you encounter some powerful evolved spiritual force detectors, it may not be able to deceive people. Moreover, when attacking, this shielding ability will be lost, just like camouflage, the attack will expose the body. Unless the evolution of spiritual power and mental power is more advanced.

  Now, the power of Muxiao's intention is only a simple operation. The power of Yuanyuan is roughly at the same level as the physical body, but the power of intention has the characteristics of being silent and invisible, and as long as the spiritual power and intentional power are combined to form an intentional divine attack, it will have an extraordinary effect, but the consumption is extremely large.

  Mù Xiāo had never stopped exploring the methods of cultivating his mental power, as long as he distinguished between using spiritual power or mental power, the consumption would be relatively reduced. Once he used incomplete mental power, it would intensify his own consumption. Therefore, he planned that unless in a dangerous moment, he would not use complete mental power as an attack method, lest the enemy kill him and his body collapse and die.

  Inside the room, there were only three stupid zombies. From their tattered clothes, Mu Xiao could tell that they were once part of the Guardian group, but had failed to evolve and become zombies instead.

  "Three zombies shouldn't be a problem, it seems that the mutant and most of the other zombies have left this room." Mu Xiao Guang Ming walked into the secret room with large strides. The three-headed zombie quickly sensed the moving object, found no breath of its own kind, hesitated for a moment, and still stepped forward step by step, as if probing like a wild beast.

  The wooden screen blocked his breath, and the zombies naturally took him as an object.

  The undead are not like withered and tattered corpses, but real living dead people, with complete bodies, strength greater than ordinary people, at least B-level physique, but their whole body is black and smelly, with a ferocious face, a pair of inhuman pupils, sharp claws like beasts, and razor-sharp teeth, just like a hungry beast-like undead.

  Ordinary old humans, without a weapon in hand, are basically unable to contend with a single zombie.

  However, Mu Xiao picked up a non-functional electric baton from the secret room and with three swift and forceful swings of the bat's shadow, directly exploded the heads of three approaching zombies that came to probe, in a completely untechnical and brutal manner. Black-red blood flowed all over the ground.

  The black blood that splashed over was directly separated by Mu Xiao's spiritual power.

  When the three zombies died, three intangible vital energies automatically merged into Mu Xiao's body. This was a "Source of Evolutionary Power", simply put, it was a kind of dense life force, which was a pure energy that only existed after evolution.

  Suddenly, he felt a surge of energy swirling in his spiritual sea, but it didn't merge with his soul. It was just drifting outside his soul's spiritual sea and soon dissipated, disappearing without a trace.

  In an instant, Mu Xiao was taken aback.
