An Rongru's hiding security room is made of extremely defensive dark metal and soft crystal, which can withstand a weight of over 50 tons. The mutant naturally does not have the power to break through such a solid defense, but the security room is not strong everywhere, for example, when the super-magnetic lock loses energy, the door can only be closed by traditional methods, that is, relying on a switch alone.

  So, An Rongyu thinks that the most defensive security room has a fatal weakness. She also unconsciously ignored this key point, after all, living in this prosperous and thriving technological era, she is used to relying on technology for convenience, thus forming a consistent thinking habit, which is also understandable.

  Mu Xiao lost his strategy, and An Rongru also overlooked the most basic things.

  The danger she faces is what she has created for herself, so she endures the external defense of mutants, fiercely striking the security hall's defenses and bringing a terrifying threat. Outside the solid metal house, every huge impact seems to hit her heart's defensive line again, the enormous pressure of panic and helplessness, her defensive heart constantly sliding towards collapse.

  If it weren't for her hopes for Mu Xiao Cang, she might have collapsed in despair and desperation long ago.

  Rumble! Rumble! Rumble!

  A deafening crash like thunder shook the night, stirring up the entire quiet villa area, and even from a distance, the echoes could be heard clearly.

  Defending against the variant is not an attack on the security hall in the same place, because no fatal weakness of the security hall has been found, so every position is tried and attacked. It's clear that when defending against the variant for the first time, it was already understood that this security hall had extremely strong defensive capabilities and could not be violently destroyed by force.

  The fragrance of the new human's blood gene is emitted, and the mutant is like an ant encountering honey, with all cells in his body filled with instinctual temptation.

  Because the genes of mutants are unbalanced, semi-finished products on the evolutionary road, the contained genes all have extreme evolutionary desires. On the other hand, the blood genes that new humans possess are stable, successful and hopeful. Therefore, new humans become the most ideal evolutionary food for mutants.

  An Rong Yu was just a weak and small new human, how could the defenders of mutants easily let go of such delicious genetic flesh.

  Boom!

  Fists like huge hammers struck, the metallic sound transmitted was different from before. The mutant's pair of sinister and venomous conical pupils flashed with a hint of blood color, staring at the metal gate for a moment, then wildly let out a sharp and ear-piercing howl. A flurry of residual shadows punched and pounded against the metal gate, frantically striking it like heavy metal music, producing a 'boom boom boom' that shook the air.

  The metal door shook with a slight tremor, gradually becoming more and more violent, as if it was about to break apart like shattered planks.

  "He must be back on time... He must be back on time..."

  The third floor of the Security Bureau, a room, An Rongru's pale face was filled with panic, her uneasy heart increasingly longing for Mu Xiao to return quickly.

  It had been a minute since Mu Xiao left, and with such a short distance, he should have been back in less than thirty seconds. However, he encountered some trouble on his way back...

  "This zombie is actually quite intelligent, and it's not just a shallow understanding. It even knows how to mobilize a large group of zombies to delay me. I only hope that An Rong Yu can wait for me to arrive, or else..."

  Muxiao drove the hot motorcycle quickly dodging, the laser gun in his hand continuously shooting out blue light beams, shooting at those dark shadows floating ghosts in front.

  In the dark of night, the zombies were unusually agile, intercepting Mu Xiao's path from all directions. Even the laser beams found it hard to kill them, and Mu Xiao's vision was impaired in the darkness, making her aim less accurate than during the day. Moreover, unless their brains or hearts were blown up, the zombies seemed unaffected, still able to charge and block her way.

  "If it weren't for underestimating the Variants' intelligence, leading to grenades being placed in useless locations, a few grenades might have been able to blast open a path!"

  The worse the situation, the calmer Mu Xiao became. To him, An Rongru was just a valuable 'pawn' to be cultivated. If her death was unavoidable, then Mu Xiao would not feel sad or blame himself, he would only think it was a pity that such a beautiful woman of the new human race had died, and that he had lost his first 'human resource'.

  But if he can save him, he will definitely try his best to save him.

  "It seems I can only use this move to open the way ahead of schedule!"

  Mù Xiāo stopped the motorcycle, stretched his hand back, and a large-caliber cannon barrel appeared, aiming directly at the security hall. He violently pulled the trigger.

  The next moment, the muzzle of the gun gathered particles of red light, electric lights wandered into strips of energy, instantly forming a massive destructive energy. A fiery red beam shot out from the mouth of the cannon, surging and gushing forth like a thunderbolt, tearing through the dense darkness...

  Boom!

  Among the massive shock, countless lightning and fire colors appeared in the depths of the night, as if the darkness was pierced through. More than a dozen zombies were annihilated in the explosive beam of light. At the same time, a source of evolutionary power surged up, and a road directly opened up for Mu Shao.

  "Seize the day!"

  Mù Xiāo suddenly accelerated the motorcycle, ignoring the absorbed evolutionary source of power that had returned. After all, these zombies only had those ten genetic resonances and could no longer satisfy his need to upgrade. The other zombies were unable to fill in the gaps, and with Mù Xiāo continuously shooting out rays of light and using his mind to hold back some of the charging zombies, he finally broke through a group of zombies' defensive line.

  At this time, a huge echo came from the security room, and the gate seemed to be getting more and more unstable, as if it was already on the verge of breaking.

  An Rong's heart gradually became desperate because she knew that Mu Xiao couldn't possibly still not have returned after so long.

  Unless Mu Xiao had abandoned her.

  "If you really..." An Rongyu's eyes glazed over, tightly grasping the wooden flute left to her by Ray, ready to take her own life at any moment, for only in death could she avoid being cruelly devoured alive.

  Suddenly, a loud bang!

  ...like something burst open...

  An Rongru heard a burst of sound, and a chill ran from her heart to her whole body, as if even her blood vessels had solidified. Just when she was about to give up all hope, another low hum and strong impact sounded.

  "This is the sound of a motorcycle...” An Rong Yu's dull eyes instantly filled with spirit, and she came back to life.

  ……

  When the mutated guard broke through the metal gate, Mu Xiao rushed back in time. The motorcycle sped straight to the position of the mutated guard, and the mental power was like a large net, locking the entrance of the security room. The ray gun shot out a dense beam of light towards the door, if the mutated guard wanted to rush into the door, it would inevitably meet the mental net and be penetrated by the ray beam.

  If it were a zombie, it would rush in recklessly to devour the food, because zombies have no intelligence, only instincts, and are not afraid of pain or harm.

  However, the mutants are different, they have wisdom, pain on their bodies, too many wounds, massive bleeding, which also affects combat effectiveness. Moreover, with the wisdom of the mutants, it is clear that Mu Xiao's appearance here now means that it will not be easy to eat the food in the security room.

  So, defending the mutant as Mu Xi understood it, without taking the risk of being harmed by the radiation beam, he rushed into the room recklessly, but surprisingly did not attack Mu Xi.

  The mutated security guard, with a ghostly aura, swiftly dodged the motorcycle that was charging straight at him and stopped at a distance that was neither too close nor too far. The mutated security guard exuded an aura of decay, desire, and brutality, his sharp pupils filled with venomous resentment, revealing a ferocious gaze that seemed to tear flesh apart.

  A chill and eerie atmosphere condensed around, the security guard transformed into a humanoid figure like a fierce ghost in the dark of night, staring intently at Mu Si who was blocking the entrance with his motorcycle, but the mutated guard did not launch a counterattack.

  "Sly guy! Trying to stall those zombies for reinforcements!"

  Mu Xiao saw through the sinister intentions of the mutated human's defense at a glance.

  Before long, a commotion gradually came from not far away, and the ghostly shadows floating in the dark night were getting closer and closer. Mu Xiao's line of sight soon saw one by one twisted and terrifying corpse faces, which undoubtedly confirmed his guess.

  Generally speaking, mutants can communicate with zombies. Now the two must have reached some kind of 'deal', which is why this group of zombies would help protect the mutant.

  Muxiao descended to the ground with a calm and collected demeanor, his eyes expressionless as he faced those terrifying pupils filled with bloodshot fury. He put down the Thunderfire Cannon that was still charging energy and holstered the Laser Gun at his waist, instead drawing out the High-Frequency Electromagnetic Military Blade from his thigh. His fingers moved slightly, and the black blade emitted a wave-like electromagnetic resonance like ripples on water.

  Fighting the Guardian Mutant with a radiation handgun is useless unless you have a specific ability to maximize its power, and it's clear that Mu Xi can't accurately hit the Guardian Mutant with high-speed movement ability now, melee combat is the best way.

  At the same time, the power of a ray gun is not as cool and deadly as a knife cut.

  But Mu Xiao said that in order to protect the mutated humans, there was a high chance that 50 or 60 zombies would rush into the security hall.

  So, sometimes people have to rely on themselves to protect their own lives.

  "An Rongru! If you don't want to die, hurry up and bring your things down!"

  A faintly indifferent voice echoed clearly in the cold and quiet room, and soon entered An Rongru's ears, who was both surprised and delighted. She was surprised that she didn't know why Mu Xiao had such a request, and she was happy that Mu Xiao could come back to rescue her in time. But there was no time for her to think more, and she also held the trust in Mu Xiao, and she had already considered herself as Mu Xiao's person, plus Mu Xiao had said before that his words couldn't be refused.

  So, An Rongru quickly picked up half a bag of hand grenades that Mu Xiao had left her before, as well as a military knife and a laser pistol, and rushed downstairs.

  From the moment he got off the bus, Mu Xiao's spiritual power filled the front 20-meter range, detecting the number of genetic resonance times of the variant human guards.

  Defender Variant has 25 gene resonances, increased to 28 at night, with unknown abilities and a body that has undergone at least one enhancement. Mu Shuo only has 18 gene resonances, which is quite a gap, but he still has confidence in surpassing Defender Variant.

  "Rip!"

  Before An Rong could react, a group of zombies in front let out a sharp scream and went into a frenzy, each one violently rising up with a bloodthirsty ferocity, launching a fierce attack. Only the mutated creature remained still, its eyes fixed on Mu Shao with a sinister and venomous glare, as if waiting for Mu Shao to exhaust himself.

  If Mu Xiou shows any weakness, the defenders of mutants will definitely take advantage of it and launch a fatal blow.

  "Haven't they come down yet?" Mu Xiao furrowed his brow, pulled out a ray gun, and with the aid of psychic powers, swiftly shot out beams of light to kill the zombies that were rushing towards him. The zombies were now attacking head-on, and with the assistance of psychic powers, the battlefield was in chaos. Mu Xiao's marksmanship was steady and accurate, greatly increasing his hit rate.

  He continued to kill zombies at a high rate, and the zombies would be killed sooner or later. This was obviously not what the defenders of the mutants had hoped for.

  Suddenly, a pungent wind came from the left side of the wood, and a powerful fist brutally struck!

  Mutant defenders can't help but launch a surprise attack!

  Mu Xiao's attention was always on it, and he instantly sensed its movements. The black, shadowless high-frequency electromagnetic military knife made a swift adjustment, slicing through that fierce fist.

  In an instant, a sense of threat, the pupils of the mutated man constricted, as if a sharp electric current had already flashed to his fist, producing a tingling sensation, without hesitation, he immediately withdrew his fist, his body defying physical inertia, suddenly and violently retreating from Mu Shao's counterattack range.

  If it weren't for guarding this entrance, or if there were no zombies around, Mu Xiao's full-force eruption just now would have completely locked down the mutated human's movements in an instant, and he could have heavily injured it with one slash.

  The problem is that An Rongru has not arrived yet, and Mu Xiao cannot leave this entrance. Otherwise, the mutated guard will enter and An Rongru's life will be in danger. In the worst-case scenario, the mutated guard will devour An Rongru's flesh and blood, increasing the number of genetic resonances and enhancing its combat strength.

  This was the scene Mu Xiao least wanted to see.
