At the critical moment, Kaiyun can be regarded as the rope that seized this opportunity. He tinkered for a while in the back seat of the pen "Fun" Pavilion www.biquge.info and put on the external power skeleton of the lower limbs of the pit viper.

In an era when the body is randomly assembled like a disassembled toy, this kind of external power skeleton is very outdated. The most common use case is basically for those who have changed their limbs to mechanical ones for the first time. After all, the way a machine moves is not the same as the physical body.

After a little movement, the boy still took off the power bone. He never wears this thing even if he collects debts, because for some reason, Kaiyun feels that he has never been able to control this thing well. He always felt that wearing this thing to exercise was like ......

How so?

It's like controlling one machine itself, and you have to control this machine to control another machine, which is indescribably awkward. Others don't feel this way, and for some reason, this feeling is very prominent in Keyun.

In the driver's seat, perhaps the pit viper was not there, and he did not feel the hostility against him, and Nogaard was not as gloomy as he had been. On the contrary, this guy turned out to be a talkative guy. Seeing Kaiyun take off his bones from the inverted mirror, he laughed, "Membranous lizard." ”

"I know." The young man threw the power bone aside: "Unless it's level four or five steel or alloy steel, otherwise it will be dead if you are rolled by your tongue, and it will be the same whether you wear it or not." It's not flexible to put it on for activity. ”

Nogard shrugged and said no more. After driving through a swampy muddy field, the jeep circled the back of a hill and headed straight for the hole at the bottom of the mountain.

After arriving at the location, Nogard gave a simple instruction to follow, and entered the mouth of the cave. This guy has a modified chest with a light device, and as soon as the light is on, he walks straight inside. Kaiyun in the back lit up a small glowing stick, and carefully followed the path that Nogaard had walked.

The entrance to the cave was not very large, it was very dull, and the air was full of a musty rancid stench. Wherever you touch your hands, you occasionally come into contact with some sticky film—something left over from the 'cataclysm' of the pre-demise civilization 400 years ago, the cataclysm that has membraneized almost everything into a thin sheet.

Fortunately, at that time, the mechanical technology was like a divine help, and the rapid development made some people decisively abandon the body that might be infected and replaced it with a mechanical body.

'Well, now is the time to think about this?' Kaiyun didn't know about history, he didn't have the heart to understand, and now he just nervously followed the light of Nogaard. In his hand, he clutched a rusty oval pistol - non-combatants were forbidden to possess weapons except for registered bounty hunters. It was Ralph's private possession, and it was given to him, which was also regarded as the importance of his debt collection mission.

'Sonic boom, shoot as close to the lizard's head as possible, and shoot as close to the lizard's head as possible. Despite Nogard's support, Kaiyun still silently recited Raf's explanation in his heart. Thinking, his hand touched forward, and he touched a film stone, and he couldn't help but curse and take a few steps back.

"Don't come out, don't come out, bite the one in front of you, bite the ......one in front of you," the young man prayed silently as he went deeper into the cave. After walking for about five or six minutes, apart from the footsteps of Nogaard in front of him, there was only the sound of ticking water, and a strange sound of machine vibration, which sounded from time to time.

Suddenly, Nogard stopped, causing Kaiyun to get nervous. He clutched the pistol tightly in his hand, tensing every string on his body, and kept looking around.

After taking a look at the place, Nogad crouched down and entered a state of alert. He turned his head to look at Kaiyun, his face was serious, and his voice was very low: "From now on, follow well, don't act rashly." ”

Kaiyun didn't know why Nogaard, who didn't care about the membranous lizard just now, was suddenly so cautious now. He was also clever enough not to ask too much, and then paid attention to it and walked to the place where Nogaard had just stopped.

Here, the space suddenly opened up, and he saw a strange terrain...... Or rather, a terrain that simply cannot appear in a cave.

In front of him, there is a cubic space with a length, width and height of nearly 5 meters, like a room, and the mud walls are neatly trimmed. Obviously, this can't be a natural formation, it must have something to do with the old man.

Could it be that the old man wanted to dig up something else here besides that mechanical body?

"Stop."

Kaiyun was wondering if Nogaard, who was walking in front of him, had noticed something, and stopped while turning off the light on his chest.

As a high-level hunter, Nogard's eyes should have been modified and equipped with infrared capabilities. In this pitch-black cave, Kaiyun's naked eye is simply incomparable. But he was also a person who had lived in this scrap iron world for 15 years, and when he heard the hunter's whisper, he instantly extinguished the glowing rod in his hand and clenched his pistol.

"Digger." Nogard quietly pointed to his right hand, and Kaiyun held his breath, and sure enough, he heard a rustle of digging sand. And through the light of the 'digger' itself, Kaiyun saw......

On the other side of the tunnel, there is a nearly three-meter-tall machine that is as huge as a mammoth. Its shape is simple, and on the main body, several square patterns are printed - what seems to be Chinese characters. The steel monster clings to the dirt layer, three massive steel arms on top, crushing the stone and digging as it digs, teleporting the dirt behind it - though there is no machine behind it to transport or take the dirt from its hands. But the 'digger' continued to repeat the norm so strictly that the dirt on his hands was spilled everywhere.

"Let it go first." Nogard exhaled slowly and stopped. His massive arm, which could not even be hurt by the saw blade of a pit viper, made a sound of flame-outing. The hunter pointed to the 'digger' and looked at Kaiyun. Although he didn't speak, the meaning couldn't be more obvious: see it, why is this place getting bigger and bigger?

"These things have been there before the Great Tribulation." After a while, the diggers were leveling the wall, and Nogard stuck out his head to look. It could be seen that he was a little impatient to wait, and he talked more: "For four hundred years, the earth has been like this, and it has been digging underground like a constant source of energy. I don't know who is still sending them signals and what they want to do. ”

He stretched out his finger and snapped: "Four hundred years ago, there were many people who hid in the underground labyrinth dug up by these diggers to avoid the catastrophe. The ruins of pre-civilizations around the world are littered with rare materials, metals, and technologies that they have hidden. Is it ......?"

Nogaard was stunned: "That old madman is digging here?" ”
