"The Mysterious System" is a rare type of ability, and sometimes its effects far surpass those of other systems. If An Xiangru really has an innate "Mysterious System" ability, then Mu Xiao would naturally change his attitude towards her, no longer treating her as just a plaything to warm his bed, but rather valuing her abilities.

  Muxiao is a pragmatic person. If she doesn't have any use, she thinks it's unnecessary to give too much expectation. She just needs to take care of herself and do some logistical work.

  "Let her stay by his side then." Mu Xiao had made up his mind.

  In the future, there will be more and more new humans in the world, with intense competition for resources and talent. At that time, mutated monsters will not be the only threat. Because when new humans cultivate various "Source Power Martial Arts" and "Soul Secret Methods", the world will turn upside down, ushering in a great era of cultivation, which is also the era of struggle for new humans.

  At that time, various new human strongmen established their own forces. Among them, the future "kings" were even more powerful figures who controlled a side of the force. Moreover, there were also strongmen from the moon... All of these could be enemies.

  In the future, those "kings" are destined to be the most successful new human evolutionists, so they are destined to become representatives of a major force, standing at the peak of evolution of countless new humans. They have extremely big ambitions, taking advantage of the world's loss of order, ruling over one side, and trying to become the masters of the new world.

  Of course, to Mu Xi, a 'reincarnator' who clearly sees the ins and outs of the entire world, those who want to rule the world are actually extremely laughable, and some extreme fanatics even want to become "gods"...

  He naturally did not participate in any childish ambition to dominate the world, but wanted to break free from the shackles of fate, sweep away all enemies, stand upright in the starry sky, and march towards eternity!

  However, all of this is still too early for Mu Xiao now. He just regards it as a pursuit of power, after all, the future is unknown and there may be crises. Therefore, he must establish his own force, not necessarily a big one, but only the elite among the new human elites, with enough capital to stand firm in front of those major forces, then he will have a stable path ahead.

  Because he once fought alone, he understood the smallness of individual strength. Especially when he saw the greatest secret hidden in the "Moon", his heart couldn't help but feel a sense of powerlessness. If one day he were to set foot on the Moon again, he didn't want to fight alone.

  Moreover, apart from uncovering a shocking secret on the moon, he also has an old score to settle with a force on the moon, so he wants to establish his own power and prepare for a rainy day.

  ……

  The night was quiet and the moonlight was cold as ice. If it were before, this time would be the golden hour with bright lights, but since the doomsday crisis broke out, around 7 or 8 o'clock in the evening became as quiet as midnight, as if the whole world had fallen into an endless abyss, people's hearts filled with uneasy fear.

  An Rongru arrived at the bathroom to wash up and wipe away her sweat, while Mu Xiao sat alone for a moment to sort out the problems that she didn't have time to think about during the day.

  Not long after, An Rongru came out of the bathroom after washing up. She was wearing a pair of shorts on her lower body, with jade-like legs that were snowy white, slender and smooth, slightly glistening with water droplets. Her skin was even more delicate and tender than before. Since all her clothes were soaked in sweat, she couldn't wear her sports jacket and bra again, so she only wore a women's T-shirt. However, her figure was truly too full and curvy, showing off her plumpness, with her breasts bulging out, almost bursting out of the T-shirt. Her incredibly mature and voluptuous body was filled with the most sensual charm of a woman.

  Musha had just taken out the mechanical inner armor and weapons, preparing to repair them once more. Especially since the mechanical inner armor hadn't fully restored all its functions yet, but the mechanical grasp had already reached the second heavy realm, allowing it to activate even more functions and strengthen the mechanical inner armor's defensive capabilities.

  At this time, An Rongru just happened to walk out extremely fiercely. Mu Xiao took a look and the * that had just calmed down not long ago showed signs of being ignited again.

  An Rongru didn't find another set of sportswear to change into, so she had to make do with a T-shirt as an inner garment. However, after putting it on, she realized that her appearance was really embarrassing. But there were no other clothes to change into, and she could only walk out with a flushed face.

  When she met Mu Xiao's fiery gaze, her face turned red and her ears were burning, her heart was racing wildly, almost melting under Mu Xiao's scorching gaze.

  "She's a mature and charming woman, perhaps not many men can withstand this kind of test..."

  Mu Xiao didn't want to let his desires control his emotions, so with an iron will, he shifted his gaze and calmly said: "You're also tired today, go sleep first, I still have things to do."

  "Uh-huh." An Rongruo lowered her head in embarrassment, her cheeks glowing like ripe cherry blossoms under the lamp light, with an unspoken allure.

  An Rongruo blushed and buried herself in the quilt, Mu Xiao shook his head with a bitter smile, thinking that after his rebirth, he had deliberately restrained his extreme personality from before, wanting to become a evolved being with humanity and emotions again. But it was indeed difficult to do as he pleased, after all, her willingness was just a prerequisite. If it were him in the past, An Rongruo, this beautiful woman, would have long become his moaning female slave under his hips.

  He doesn't think about those absurd and boundless chaotic memories from before, changing his mindset, looking straight at the road to his future.

  In the basement of the lawyer's building, Mu Xiao took three out of nine A-level "Golden Steel - Mechanical Inner Armor" equipment. One he wore himself, one was An Rongru's, and another was left for his younger sister Mu Xuan Yin. At that time in the lawyer's building, Mu Xiao's "Mechanical" ability only had one layer, but now he has reached two layers, allowing him to repair half of the Mechanical Inner Armor's functions, increasing its defensive power.

  His mind was like a precise optical brain, emitting fine light lines from his hands, connecting to the mechanical armor's internal core like data cables, continuously transmitting data to the mechanical armor's internal core. He first cleared out the electronic viruses hidden inside the mechanical armor's internal core, and then repaired the programs that were destroyed by the electronic viruses.

  The world's air molecules have transformed, and only then will there be this previously inexplicable ability.

  In the face of a major evolutionary era, all unimaginable and mysterious things will become a matter of course.

  With the consciousness data of the mechanical secondary boundary, he smoothly completed the repair of the "energy" defense system. Now, the internal armor defense degree of the machine can withstand a impact of 2,000 kilograms without damage, and it will only feed back to the physical body and cause harm when withstanding a maximum of 3,000 kilograms. Moreover, it can eliminate energy below level A, that is to say, A-level weapons cannot break through the defense degree of the machine's internal armor.

  Of course, if you encounter a huge impact many times, the energy stored in the mechanical armor will also be consumed faster. Once it is completely consumed, the defensive power of the mechanical armor is not as good as an iron plate.

  "If you encounter a mutant, the mechanical inner armor has energy defense capabilities, at least it can reduce the damage of the mutant by half." Mu Xiao nodded in satisfaction and began to process the next piece of mechanical inner armor.

  He became the new human "top" physique, with physical strength of around 5,000 kilograms or more. As his physique improved, his physical strength would also increase. Generally, when a new human "top" physique reached its peak at the 12th level, their physical strength was around 16,000 kilograms. With just pure physical strength, they could kill any being in the genetic resonance realm with one punch. Moreover, the energy produced by advancing to this realm was even more formidable than physical strength. Once he mastered the Source Force martial arts, his power would undergo a qualitative change and no equipment from this era could defend against it, unless it had been specially modified.

  However, upgrading one's physical body is a difficult task. Some people are satisfied with the 100th genetic resonance and enter the realm of cultivation evolution, where their physical body has been somewhat strengthened. Among most new humans, only the "top-notch" physical body exists, and if they want to further upgrade their physical body, they have to find another way, because upgrading one's physical body is not just about enhancing muscles, but rather a comprehensive enhancement of the entire body.

  But Mu Xiao has a kind of "Primitive Source" that enhances his innate talent, and also has the ability to swallow blood energy to strengthen his body. He also has memories of many cultivations before rebirth, which gives him an advantage that others do not have, so he can cultivate either "Source Power Martial Arts" or "Soul Secret Methods" without any harm.

  Next, Mugen was busy repairing the mechanical inner armor, but the automatic detection system and the automatic defense system had not been successfully activated. If fully repaired, the mechanical inner armor could release energy to form a golden steel shield, achieving full-body defense with no blind spots.

  The energy defense system that has been successfully repaired, the mechanical inner armor worn on the body can only defend the upper half of the body, but the limbs and head outside the body are not included in the defensive range.

  Muxia repaired the three mechanical inner armor, restoring its energy defense system. Although it couldn't achieve perfect defense, its defensive power increased greatly, equivalent to reducing its weak points and adding an extra layer of safety. As for the remaining radiation handguns, high-frequency electromagnetic military knives, and thunderfire cannons, Muxia also overhauled them, allowing the weapons to exert their normal lethality, even increasing their performance by around 10%.

  Put away some equipment in the backpack, and put the equipment and weapons to be used tomorrow aside. Then tidy up the things in several backpacks, so that you can set off early tomorrow morning.

  After Mu Xiao had done everything, he sat down to enter a meditative state, optimizing his blood energy, spirit and strength. He let his blood flow freely, nourishing the injuries left from battle, clearing his mind of distractions, softening and spreading his spiritual power, sensing the energy molecules present in the air, enhancing his sensitivity to the source energy particles after subsequent cultivation.

  Meditating until midnight, Mu Xiao adjusted himself to his best state.

  In fact, his main purpose of practicing asceticism is to make the soul after rebirth more compatible with the body in the past.

  Mushan could sleep or not sleep, but he had a mind to take in An Rongru and make her his own, so naturally he didn't want to let go of the opportunity to capture her heart.

  Moreover, Mu Xiao could see that An Rongru didn't mind him too much, which was a good sign.

  "In the future evolutionary era, it's really hard to find someone trustworthy. Only when this disaster begins, there are people who suffer together with me, and they are barely trustworthy. I hope she won't disappoint my trust in the future..." Mu Xiao looked at An Rongru who was already exhausted on the bed for a whole day.

  In the face of disaster, humanity has an extremely ugly side, but this world is two-sided, and there are also extremely kind and just people. However, such people are really too few. Nevertheless, it cannot be denied that a deformed fact, whether it is a deviant evolution or an evil evolution, as long as they had friends who went through hardships together before the end of the world, their friendship must have been deep.

  Perhaps the world has collapsed, humanity has become untrustworthy. If we can't preserve that last shred of human emotion, then it's no different from being a mutant. Humanity is filled with negative emotions and will eventually stumble on the path of evolution, losing its humanity and becoming an alien creature.
