The latest update of the wooden Xiao, based on the direction of the villa area, roughly determined that the left road might lead to an unknown place. He then released the data power of "Mechanical Palm Control", hacked into the optical brain system of the metal gate, and opened the door, revealing a passageway.

  "It's another standalone terminal, no host computer..." Mu Xiao withdrew the data force from her hand and received the feedback information, learning that this metal gate was the same as the one in the underground room, with no connection to any host control.

  This passageway is still without lighting and is no different from the one behind it.

  "Let's go, Xiaoyin."

  "Uh-huh."

  The two continued to venture deeper, but the atmosphere grew increasingly eerie and oppressive. Every three hundred meters, a metal gate blocked their path, as if the darkness was holding captive some terrifying monster. A massive, brutal, bloody, icy, and deadly pressure surged forth like a tidal wave.

  As time passed and the atmosphere surged, Mu Xiao basically confirmed that this passage was not leading to the villa area, but somewhere else.

  Muxiao and Muyin walked for over ten minutes, and finally, there was a new change ahead. A metal gate with an armed system, which contained extremely intense high-pressure electromagnetic force, enough to kill S-level physique people instantly. However, the metal gate that lost the control of the light brain could not activate this armed system. Muxiao easily opened the gate.

  When the metal gate opened, a metallic passageway appeared with alloy walls and floor.

  "It seems to be getting more and more interesting." Mu Xiao's eyes shone brightly in the darkness, with a strong premonition that there might be a huge secret hidden deep inside.

  "Brother, do you know what's inside? Could it be an underground city?!" Mu Xuan's voice was also filled with curiosity, the mech system continuously scanning the metal passageway, trying to find any clues.

  "In this world of unknowns, it could be a wonderful encounter or a fatal disaster, but as we move forward, the answer will naturally reveal itself." Mu Xiao possessed unwavering confidence and stepped into the metal passageway.

  During this period of time, Muxin almost completely understood all the system functions inside the mech, her body and the mech's coordination were getting better and better, reaching a very high synchronization rate.

  Her mecha walked on the metal floor, issuing a series of heavy and powerful loud noises that echoed clearly throughout the entire passageway.

  "Xuanyin, you look like a giant."

  "Brother, you look like a dwarf."

  The two of them joked with each other, without any tension about entering an unknown place at all.

  This passageway is made of metal, so it must have other uses. However, the divine power of Muo Jing can't detect anything unusual. If Shan Miao or Jiang Yue were here, with their ability to see through things, they would definitely be able to detect something clearly.

  According to the previous pattern, there should be a metal gate every 300 meters ahead, but this time they had walked over 200 meters and neither Mu Xiao nor Mu Xuan had seen any metal gates. Just as Mu Xuan was about to mention this issue, she discovered strange fluctuations on her mecha's radar, which seemed like electronic interference waves, yet also felt like a life force with hostile intentions.

  "Brother..." Mu Xuan's voice had just reminded him.

  "Hmm. I've sensed some movement ahead, be on your guard." Mu Xiao also sensed that strange wave and suddenly recalled a memory from his past life, where he had encountered electronic waves and life energy similar to this... perhaps it was that creature.

  Crack!

  The metallic switch clicked, and five dark shadows suddenly jumped out in front, almost merging into the darkness. They were so fast that it was impossible to see what kind of monsters they were at first glance, only seeing pairs of eyes emitting deep red light, bringing heavy and ferocious auras as they moved at high speed.

  "Strike!"

  Just as Mù Xiāo was reminding Mù Huìyīn, the five black shadows lit up with flames and actually launched an attack a step faster than Mù Huìyīn, spewing out trails of fire that bit like a snake in the darkness.

  Dada dada dada!!......

  Flickering flames, dense flame bullets shot towards the direction where Mu Xiao and Mu Xuan were, while five black shadows emitted a chilling aura that annihilated everything, rapidly closing in.

  Mù Xiāo spoke as the Yuan Li transformed into an invisible large shield, blocking all incoming flame bullets. Mù Biǎo understood that he had lost the initiative to attack, so he raised his mechanical arm and activated the defensive stance. On his arm appeared a diamond-shaped metal shield, with a surge of energy generating on its surface, increasing the shield's defensive power and impact resistance.

  "Hah!"

  Maki's voice let out a clear and crisp yell, her feet suddenly moved, the power of the Double Realm circulated throughout her body, the mech burst forth like thunder and charged forward with a fierce tackle, brutally colliding with a black shadow. The energy cannon in her other hand shot out a flame tongue, fiercely sweeping across the nearby black shadows.

  Bang!

  A black shadow was directly hit by the metal shield on the wooden decoration machine, violently colliding head-on with a force of at least 8,000 kilograms. The black shadow flew out like a broken kite and heavily fell to the metal ground, exploding into a burst of electrical sparks. After convulsing for a moment, it got back up again.

  "Is that a dog?" Mu Xuan's voice had just discovered the true face of the black shadow, although it was twice as large as a normal wolf dog, but in its muscles, mechanical parts were installed, like steel muscles growing in flesh and blood.

  Bang! Bang! Bang!...

  At this time, Mù Yuèyīn heard a fierce collision sound from the rear, turned her head to look back, and found that those four half-biological half-mechanical wolf dogs had already been locked down by Mù Xiāo's Niǎnyuán power, with all four limbs suppressed on the ground, unable to break free from the constraints of the Niǎnyuán power.

  The mechanical wolf dog struggled and resisted, emitting a hoarse low growl like metal friction, as if it understood speech, repeating a segment of language.

  "Annihilate——destroy——invade——invader——annihilation——"

  "Watch out, behind you!" Mu Xiao shouted, seeing the mechanical wolf dog that had been knocked back by Mu Xiao's sonic boom suddenly recover and transform into a ferocious speed like lightning, revealing a pair of sharp metal claws as it pounced forward with a fierce killing intent.

  Just as Muxiao reminded her, Muchen received a warning from the mech system. Her body quickly spun around, but she didn't have time to pull out the energy double-bladed long knife on her back and the dagger on her thigh. However, a cutting blade extended from the mech's wrist area, swiftly slashing with its sharp edge gleaming with electricity, accurately cutting the mechanical wolf dog that pounced at her into two pieces, with a large amount of blood and sparks bursting out.

  "Annihilate - destroy - invade - invader"

  That mechanical wolf dog's body was severed in two, yet it still didn't die and let out a hoarse, eerie voice.

  "Brother, what kind of mutant creature is this? How can it be so strange..." Mu Xuan Yin put away his shield and machine gun, took out the double-bladed long knife from behind his back, poked at the half-dead mechanical wolf dog, and found that its lower body was constantly bleeding, while also leaking energy fluid. Moreover, most of the internal organs were mechanical.

  "I've taken down one... actually, it might be possible to tame them." Mu Xiao suppressed the four mechanical wolf dogs and said: "These are bio-mechanical dogs that have undergone mutation. After the mutation, their flesh and machinery merged into a single entity, presenting an alternative form of life. Therefore, the machinery on the mechanical dogs has not lost its spirit, as it has become part of their bodies. They can even utilize the modification of machinery to speak human language."

  "It was such a monster, and it can be subdued." Mù Xiǎo's voice was small as she pouted: "Brother, why didn't you tell me earlier? Then I would have spared its life and not cut it in half."

  "I just remembered... Besides, the bio-mechanical dog appeared too suddenly and didn't have time to say anything." Mu Xiao looked at the half-dead bio-mechanical dog and said: "Since this bio-mechanical dog can't be repaired or treated, let's just destroy its core brain and obtain the evolution source. Who knows, we might even get a mechanical ability."

  "Uh-huh." Mokuren wasn't the first to slaughter monsters, and she cleanly pierced the head of the biochemical mechanical dog with a swift motion. The intermittent mechanical voice also stopped, leaving only four biochemical mechanical dogs that were still repeating on the ground.

  Bio-mechanical dog probably has about forty times of gene resonance, but Mu Xuan's tone is higher than this number, not enough to boost one time of gene resonance. However, as Mu Xiao expected, a "mechanical" source appeared from the dead bio-mechanical dog, and it was even a specialized degree.

  "Brother, how did you know that these mechanical dogs have mechanical abilities?" Mù Jiǎo's voice was filled with excitement as she absorbed the "mechanical" source, getting one step closer to "Mechanical Control".

  "It's just a guess." Mu Xiao brushed it off, unable to tell Mu Xuan that in the future when Earth and the Moon truly clashed, the Moon would release a large number of "Bio-Mechanical Species" to fight, attempting to regain the initiative on Earth.

  Now, Mu Xiao roughly guessed what was at the depths of this passage, but it was hard to estimate how many of these "bio-mechanical species" existed inside.

  Muxiao was thinking about something when Muzhuangyun asked a question that almost made him faint.

  "Brother, can we take these mechanical dog's meat back home to eat?"

  "Take it back and eat it yourself?"

  "I want to give it to you, brother."

  ……

  Mu Xiao temporarily ignored the strange idea of this little girl, and began to fully activate her own data power, invading the core light brain in the head of the biochemical mechanical dog, modifying the data inside, obtaining the authority of the biochemical mechanical dog, and then she could take it for herself.

  This high-end "bio-mechanical" technology was not developed by Earthlings, but is a highly advanced technology that fell from space shock waves and is the product of another advanced civilization.

  Mù Xiāo's current uniform bio-mechanical dog is the lowest level, can be said to be a rough product, only with tearing and biting and small machine gun attack power, but the physical combination of mechanical characteristics, just enough to have top-notch physique one realm, however this is after mutation strengthening.

  The "Bio-Mechanical Species" has no special abilities, mostly only having the three abilities of "Mechanics", "Weapons", and "Fighting". However, they can devour any energy and flesh, possessing a very strong digestive ability. They can strengthen their physical strength by absorbing biological blood and flesh, and even absorb biological genes to exhibit some special characteristics. Additionally, they have an extremely strong killing instinct.
