Countless heavy lead blocks appeared out of nowhere from the hangar ceiling, crashing down heavily.
Those mecha infantry hit were all knocked down, causing chaos.
But their external armor was very tough, and their power was strong. Driven by powerful mechanical energy, one person could lift several tons of lead blocks.
While those mecha infantry struggled to move the lead blocks off themselves,
Gu Ya mentally asked, "Hei Yang, finished?"
"Sorry Master, underground technology is completely different and requires more time for analysis." Hei Yang spoke very quickly.
"A few minutes!" Gu Ya loudly asked.
After a two-second pause, Hei Yang replied, "It will take about an hour."
"Shen Jingming! Deploy the pitch-black domain and get us out!" Gu Ya roared.
Shen Jingming calmly stated, "Without mecha protection, non-partners will die upon entry."
Damn it! Gu Ya was furious. Summoning mechs in such a cramped space would not only crush enemies but also their own people.
"Gu Ya, don't rush," Mu Ye Xing Chen said calmly. "Take a closer look at their armor."
Receiving the hint, Gu Ya looked closely. The armor of those mecha soldiers was very familiar; it was their mechs shrunk down and wrapped around them.
Not only could they summon large mechs for combat, but they could even shrink the mechs down several times to become exoskeleton armor for fighting in confined spaces.
This was interesting.
"Wait a few minutes!" Gu Ya called out softly, quickly recalling Hei Yang. "Recycle our mechs, shrink them into exoskeleton armor! Fast!"
"Easy, Master," Hei Yang said, returning to work.
Shu Feizhang roared angrily, "Gu Ya, they're charging!"
"Wang Chuan!!"
Gu Ya instantly summoned his consciousness avatar. Four people became five, all equipped with exoskeleton armor.
The five formed a circle, raised their electromagnetic charging grenade launchers, and unleashed full power output at the advancing enemies.
The grenade shells were fired and exploded in mid-air, instantly releasing the violent energy compressed within.
Spiky electric nets suddenly spread out, lunging at the enemies.
Tens of thousands of volts of electricity spread "crackling" around the enemies.
Around Gu Ya and the others, a giant ring of high-voltage current was formed, spreading electricity outwards.
The lights were extinguished, and the hangar was plunged into darkness.
The air was instantly filled with the pungent smell of ozone, released from oxygen being broken down by high-voltage electricity.
Just as the enemies were paralyzed by electricity, a crimson light ring suddenly lit up in the darkness, and ten crimson light swords appeared in the hands of Gu Ya and his companions.
Gu Ya and Wang Chuan vanished from their positions, leaving four straight red light trails in the darkness, cutting towards the enemy ranks.
The other three raised their light swords and charged in different directions towards the enemies.
In an instant, the hum of light swords, the sound of metal being torn apart, dull shouts of pain, and the thud of heavy armor falling echoed in the darkness.
Gu Ya and Wang Chuan turned into two crimson dragons, weaving through the gaps in the enemy ranks.
The other three showed no mercy, their swords flashing, striking down defenseless enemies.
The battle lasted only a few minutes. Before Hei Yang could finish shrinking everyone's mechs,
Gu Ya released over a dozen holographic lights, floating in mid-air and illuminating the entire hangar.
On the ground, all the enemies were dismembered. Their neck armor was cleanly severed by the scorching light swords, and the high temperature instantly sealed the wounds, preventing blood from spraying.
Some mechs even had their heads sliced off diagonally. Inside the thick armor, brain tissue mixed with molten steel, creating a terrifying sight.
The smell of burning flesh also began to spread through the air.
Qiao stood there dumbfounded. Because he was standing far away, he was not hit by the electric net and survived by luck.
With his leg thrusters firing, Gu Ya quickly flew over. With a horizontal and vertical slash of his light sword, he severed the opponent's weapon, then pointed the sword at its head and said coldly, "Ungrateful waste! This is what happens when you anger us!"
Shu Feizhang strode forward, swung his heavy fist, and landed a solid blow on Qiao's mecha helmet.
Qiao stumbled back two steps and fell on his backside. He frantically waved his hands and shouted, "Don't! Heroes, don't kill me! I was just following orders!!"
Mu Ye Xing Chen walked over from behind, his gaze cold and proud as he looked at Qiao. He said coldly, "Take off the armor."
After a series of messy mechanical sounds, Qiao's exoskeleton mecha vanished completely. His panicked and terrified eyes widened even further!
"Let's go chat."
Gu Ya grabbed Qiao by the collar and dragged him out of the hangar like livestock.
The urgent sound of mecha thrusters could be heard as four mechs soared into the sky, leaving the camp littered with corpses.
In the mountains, the group found a hidden cave, cleaned out the mice, insects, snakes, and spiders, and made it their shelter.
Qiao, stripped down to just his underwear, was curled up in a damp corner.
Under the glow of the lights, the shadows of Gu Ya and the other three flickered on the cave wall, like devils dancing in revelry.
"If you want to live, answer our questions honestly. If I find you hiding or lying, I will torture your body in ways you can't even imagine," Mu Ye Xing Chen said sinisterly.
Gu Ya asked coldly, with an irrefutable, unchallengeable tone, "Tell us the theory, principles, usage methods, and drawbacks of your ability to summon, recycle, and shrink mechs."
Qiao looked at Gu Ya with his round eyes, unblinking, and said, "The theory can't be summarized in a few words. The principle is to use a unique space to hide mech components and retrieve them when needed."
"The ability to shrink mechs means there is already a set of small exoskeleton mechs stored in the unique space."
"The unique spaces of ordinary people are passed down to the next generation. The drawback is that after three generations, the unique space will gradually lose its effectiveness."
Gu Ya punched Qiao in the face, his voice full of anger. "Tell me the truth!! Do you guys specifically kill Dunsaxin people! And seize their unique spaces!"
Qiao's pupils trembled, and he quickly shook his head, "We don't do evil deeds!"
"Specific method!" Gu Ya roared.
Qiao stammered for a long time, then finally sighed and slowly said, "There is a very small area in the brains of Dunsaxin people that is different from normal humans. They seem to inherently grasp some cosmic law and can use spatial abilities."
"According to research, each Dunsaxin person's unique space is a small space independent of the real three-dimensional universe."
"According to research..." Qiao looked at Gu Ya with his big round eyes and said, "It's a 3.24999-dimensional space. Every Dunsaxin person is a gateway to another world."
"Even the Dunsaxin themselves don't know how they evolved this ability."
"Existing ancient solitary records state that they are the oldest indigenous inhabitants of the planet. And our planet was not like this originally."
Gu Ya forcefully pressed Qiao's bald head and shook it vigorously, roaring, "I'm asking you how to seize the Dunsaxin people's unique spaces, don't bore me with history!"
Qiao, acting like a panicked official, stammered, "Marry a Dunsaxin person, and regardless of whether the offspring is a pure Dunsaxin descendant or a normal person, they will have a unique space! Ah—!"
As Qiao's pained scream echoed through the cave, Gu Ya rubbed his head forcefully against the cave wall. Qiao's right cheek was immediately bloody and mangled.
"Don't kill him, he's still useful," Mu Ye Xing Chen stopped him in time.
Shen Jingming remembered Hong Lian Zhi Wu again and his mood suddenly became low. He walked out of the cave silently with his head down.
After giving Gu Ya a few instructions, Mu Ye Xing Chen also left the cave.
"It's that simple!?" Gu Ya grabbed Qiao by the collar and asked fiercely.
Qiao, in pain almost to the point of fainting, nodded with half a bloody face, "This isn't a secret!!!"
"The chance of having a pure Dunsaxin descendant after marrying a normal person is one in eighty-five. Some Dunsaxin people traveling abroad also actively combine with ordinary people for bloodline continuation."
"That's why people like us who can use unique spaces exist!"
Gu Ya retorted coldly, "So you're a surface dweller, and you lied to us? Why won't you let us return to the surface!!!"
"Heh!" Qiao, however, chuckled coldly and said, "Surface dwellers are greedy. Once you let you return, it will attract a vast number of surface dwellers! The underground world will eventually be lost!!"
Shu Feizhang, who had been listening all along, nodded and said, "That's indeed possible."
After speaking, Qiao tilted his head back and fainted from the pain.
Gu Ya said to Shu Feizhang, "Meaning, if we want to study void technology, we must study Shen Jingming."
Shu Feizhang nodded thoughtfully and said, "The problem is back to square one. Xian Xia has tried many methods, and hasn't succeeded even after trying to dissect him."
At this moment, Hei Yang's voice finally came through, "Master, the miniature attachable mechs have been developed. Additionally, I have found a breakthrough in underground technology. My abilities are limited, and I still need Master to personally research it."
