[Accompanied by a sudden buzz that pierced the air.]
[Your huge iron fist wrapped in a fine gold chain continuously bombards the tall body of the Shadow Prison Forbidden Army!]
[Under the double crushing force and speed, the opponent strode backwards with almost no ability to fight back. 】
[In just tens of seconds, the shadow prison guards, whose tall bodies are constantly shaking violently, have tried to escape from your attack range completely several times, but they have never been able to escape your agile pace that is almost like a shadow! ]
【Boom!】
[Once again, you swung the huge iron fist and hit the metal helmet of the Shadow Prison Guard hard. With a large number of fine gold fragments flying out, you completely knocked the opponent down to the metal floor! 】
[And in order to prevent the other party from continuing to stand up and resist, you even deliberately raised your heavy feet and stepped heavily on the other party's breastplate several times. 】
[It wasn’t until the shadow prisoner, whose power armor was nearly in a broken state, suffered a lot of heavy blows to his head and torso that he temporarily lost consciousness. Then you slowly stopped your crazy attack. 】
【"hiss--"】
[You suddenly exhaled a mouthful of hot air from your mouth, and the iron fist wrapped in a fine gold chain subconsciously dropped to your side.]
[You leaned over slightly, and with your other hand, you snatched the unique relic spear from the Shadow Prison Forbidden Army.]
[You shook your tall and strong body, stepped over the still unconscious Shadow Prison Forbidden Army, and continued to advance towards the depths of the silent corridor ahead. 】
[Dongdongdong——]
[However, holding the ruins spear, you have only advanced about a few kilometers. 】
[Along with another burst of heavy footsteps that echo through all your superhuman senses.]
[A five-person Shadow Prison Forbidden Army combat team quickly stepped through this straight, dimly lit and silent corridor, rushing towards you! 】
["Out-of-control taboo things! This is not a place where you can be arrogant, get back here immediately!"]
[A shadow prisoner wearing a gold-rimmed and black-bottomed Skyhawk Terminator roars at you in a low voice.]
[The next second, the Rustum-type storm bolter held tightly in the opponent's palm instantly burst out with extremely terrifying dazzling fire, and Kraken bombs that penetrated the air were directed at your tall body.
It started shooting quickly!]
【ding ding ding——】
[You suddenly raised the huge iron fist wrapped in adamantine chains, guarding it firmly in front of your unprotected head. The flames of exploding bombs almost drowned your observation line of sight, and
The adamantine restraints all over your body will make your stomach buzz.】
[But just when you subconsciously want to shake your tall body, use agile offensive steps, and completely close the distance with the Shadow Prison Forbidden Army team. 】
【Buzz buzz----】
[Accompanied by a sudden and terrifying buzz that echoed all around.]
[A large group of densely packed nanomachines gathered in mid-air. The overall appearance looks like a dark storm, and the nanomachines frenzy is like a sudden violent wind and rain, spurting out from the silent corridor behind you! 】
[At this moment, you, who is being bombarded by explosive bombs, are not surprised or confused by this. 】
[In an instant, the wave of nanomachines that seemed to be wantonly controlled by an invisible entity quickly passed by your tall body, completely swallowing up the five shadow prison guards in front! 】
【Chichichi——】
[As the air continues to emit the creepy sound of metal disintegrating.]
[Wait until the tall figures of the five Shadow Prison Guards reappear within your field of vision.]
[Almost naked, they were lying on their backs on the metal floor. Their eyes were closed tightly, making these shadow prison guards as peaceful as dead people! 】
[If it weren’t for the heaving chests that completely revealed that these forbidden soldiers were not really dead, you might even think that this would be another defensive measure in the underground prison. 】
["Uh...David?"]
[You suddenly took a deep breath.]
[You carefully asked softly towards the frenzy of nanomachines swimming back and forth in the silent corridor. 】
[At this moment, these densely packed nanomachines seem to have received some password.]
[They quickly appear within your field of vision, condensing a jet-black metal giant about five meters high out of nothing!]
["My lord, I have successfully arrived, praise the emperor!"]
[At this moment, facing this metal giant whose mechanical voice is unusually deep and deep, but whose speech tone is extremely familiar, you slowly relax your guard. 】
["David, what have you become? And why are there so many weird things in the underground prison of Terra Palace?"]
[You shook your round head with sky-high braids slightly, and asked the iron man David, who was even taller than you.]
["My Lord, although I can dig out not much original information, but if I guessed correctly, this is probably a fighting Iron Man from the Iron Man Rebellion era... and the opponent seems to be the kind of Iron Man who is in the command class.
General!"]
[Iron Man David, whose eye sockets gradually light up with a blue light, speaks to you in a low voice.]
[At this moment, you couldn’t help but stare at the Shadow Prison Imperial Army team not far away, which was almost instantly eliminated, and then at the Iron Man David who was close by Chi Chi. ]
[You subconsciously let out a sigh from your mouth.]
["How strong were humans in the Golden Age? How could they still win against a combat-type Iron Man of this level?"]
[Iron Man David, who listened attentively, also quite agrees with your sigh.]
[However, it also indicates to you that perhaps the battle damage suffered by the iron man in front of you is too severe, or some restrictions have been added to it. 】
[Even if the power armor that has devoured several Shadow Prison Guards is used as an energy supplement, it will take a cooling-down period to launch an attack mode similar to the nanomachinery frenzy again. 】
[You nodded slightly towards Iron Man David to express your understanding.]
[You hold the relic spear in your palm tightly, and walk deeper into the silent corridor with Iron Man David, who has become an Iron Man General.]
[Soon after, you gradually passed many taboo objects that were completely imprisoned, such as evil things like the Chaos Demon.]
[But you also saw many empty cells whose doors had been damaged, and the taboo objects inside had escaped for who knows how long.]
[As time goes by, you and Iron Man David quickly passed through the silent corridor and the maze-like underground shadow prison, and finally came to a mysterious underground cave surrounded by natural cave landforms. 】
