Zizi –

White smoke rises.

The corroded alloy door panel was cut into three neat gaps by the red laser beam, and as Jiang Feng stretched out his hand and pushed forward, he fell to the ground with a bang.

Behind the alloy gate is a spacious cavern that, judging by the waxy yellow minerals remaining on the walls, is supposed to be a uranium mine. However, it is clear that the radioactive sources that contaminated the entire Damned Rift were not caused by these natural uranium mines, but by the technical means that these uranium ores were made into enriched uranium that could be used for fission reactions.

"Underground facilities built in uranium mines? I really think about it. ”

Glancing at the minecart that had fallen to the side, Jiang Feng pulled out a flashlight from his waist and continued to walk along the tunnel.

The tunnels are not very deep, but they have many forks in the road, and many of them are connected to each other, forming an intricate labyrinth. If it weren't for the help of the brain, Jiang Feng might really get lost here.

Not only is the terrain intricate, but there are also traps to keep intruders at bay on many stretches of road.

As for the types of traps, there are all kinds of traps.

Spell traps like the most primitive Fall Holes and Spikes, or Acid Swamps, and even a little more clever are the IR-aimed Sentinel Rifles and Triggered Jumping Mines. However, those high-tech traps are all old and broken due to disrepair, but those primitive traps remain.

However, this level of trap, in front of Jiang Feng's 4-point perception, is no different from mud.

Picked up a stone bullet and sent it out, and the bell fell to the floor with a bang.

I saw more than 30 sharp spears piercing out from the side of the wall, stabbing the spot where the stone fell into a hornet's nest.

"Is it possible to combine inscription technology with mechanical gears and apply it to trap technology? If Fielding had been here, he would have been interested in the structure of these traps. The flashlight shone on the walls on both sides, and Jiang Feng muttered to himself.

He was sure that the person who lived here must be a person with severe victim paranoia.

There are so many traps set up in your own home, and I am afraid that it will not be easy to go home.

After turning a corner, Jiang Feng walked to the end of the tunnel. Directly opposite him was a poorly made elevator, and from his feet to the position of the elevator, there was a layer of iron sheet that would make a "clang" sound when stepped on.

Exposed wires can be seen on the walls around both sides, as well as the keys used to enter the code. Jiang Feng guessed that part of the line here should be used to control the paralyzed sentry machine gun traps outside, and the other part was used to control the elevator in front of him.

The power system has been paralyzed, and it is impossible to start the elevator by normal means.

Jiang Feng ordered the ghosts floating beside him.

"Ghosts, cut off the elevator."

【Received】

An icy electronic voice replied, and the silver metal ball floated forward.

The crimson laser beam was released, and brilliant sparks shot out, and it didn't take long to cut the rusted steel cable at the top of the elevator.

There was a tooth-aching grinding sound, and the elevator, which had lost its suspension, fell into the bottomless pit, and with a muffled sound of hitting the ground, everything fell silent.

"That's it."

Walking forward, Jiang Feng looked down at the deep pit below the elevator.

Through acceleration and echo time, he had calculated the depth of the tunnel to be about a hundred meters, took out a nylon rope from the space ring, tied it to the steel bar next to the deep pit, and then bit his hand and nodded, grabbed the rope and slid down.

His feet touched the ground, and Jiang Feng didn't have time to stand firmly,

The red signal light in front of him suddenly lit up, and a dry electronic sound sounded.

"Alert! Intruders. Alert! Intruders. ”

With the noisy sound of fans, four drones that had been abandoned for an unknown number of years staggered up, holding four barrels with flashing electric sparks, and flew towards Jiang Feng.

Not to mention whether the weapon can still be used or not, in this way, most of the time even the control elements are broken, and it is a miracle that it can fly.

Not even bothering to escape with a gun, Jiang Feng picked up a steel bar from the ground and directly smashed three drones, while the remaining one was robbed of the head by the ghost who fell, and released a laser beam to shoot it through.

Throwing away the steel bar in his hand, Jiang Feng clapped his hands and looked at the end of the line guarded by the drone.

"Is there the end ahead?"

Unlike the heavily guarded tunnels, the final point turned out to be just an ordinary iron gate.

He stepped forward and pushed it, and found that the door was locked from behind, so Jiang Feng beckoned the ghost to come over and performed a simple surgical operation on the crack of the door, cutting off the iron bolt inserted in the back of the door.

Bell Boom –

There was a soft sound of metal falling to the ground.

Pushing open the door, Jiang Feng walked in.

Behind the door is a circular crater, in the center of which is a metal pillar two to three meters in diameter, and an iron bridge leads to the opposite side, judging by the intricate pipes below, it should be a nuclear fission reactor, and it is an extremely rudimentary and extremely unenvironmentally friendly reactor.

"Groundwater is used directly as a heating medium and untreated wastewater is injected directly back...... It seems that the builders of this facility had no intention of staying here for long. ”

"The pool on the left is nuclear waste, and on the right is enriched uranium...... Although it is almost natural decay now. ”

Shining a flashlight on the pools on both sides, and looking at the iron barrels marked with danger marks, Jiang Feng continued to move forward along the rusted iron bridge, and after passing through the metal column, he came to a room that covered an area of about five hundred meters.

The things in the room were messily arranged, and the yellowed books were discarded on the ground so haphazardly, with unknown magic arrays depicted in some places, and a few mechanical parts that had not yet been assembled were scattered in other places.

It can be seen that the owner of this facility is a freewheeling person, who will tinker with the technology of the idealistic side for a while, and then go back to the study of science.

"This guy has taken the identity of a traverser to the extreme."

Even a nuclear reactor can be built, and the word genius is not enough to describe his intelligence.

With a sigh of admiration in his heart, out of curiosity about his motive for building a nuclear reactor, Jiang Feng searched around with a flashlight, trying to find some clues from the things left here.

Suddenly, he noticed something strange.

He remembered that when he entered the nuclear reactor, the iron door was locked from the back, but he did not see a trace of anyone here. Even if the owner of this facility dies here, there must be a corpse, right?

Just then, his eyes were drawn to something placed in the corner of the room.

It was an inverted U-shaped metal arch with thick silver pipes interlaced at the base. Judging by the carved patterns at the base of the arch and the remnants of magic in the silver tubes, the facility must have used ancient inscription techniques.

Right next to this arch lies an open notebook.

Intuition told Jiang Feng that this thing should be able to tell him the secret of the arch in front of him.
