It was a submarine.

The total length is about 90 meters, and the displacement is not visible, but it is certainly above 1,000 tons.

It is like a needle of the sea god, deeply embedded in the rugged stone wall.

Most of the surface is covered in unknown algae, and the fissures are cemented by the remains of molluscs. The rust mottled the iron sheet, but it did not remove the white paint that symbolized its identity.

Reaching out his hand, he touched the cold iron wall through his glove.

Gently brushing the soft and slippery seaweed, Jiang Chen muttered out the dead characters.

“U-235？”

If he remembers correctly, there should be only one series of submarines in the world that start with the U number - the German U-boat.

Jiang Chen is not a military fan, and his understanding of this thing basically comes from a British-made World War II documentary and several Hollywood films.

The ghosts that were active below sea level haunted the Allies like nightmares, tormenting merchant ships and transports sailing across the Atlantic. Tearing apart the supply lines of the free world and the British Isles, and holding back the sea power of the Allies.

It was not until the surrender of Germany in 1945 that these submarines sank and sank.

"The legacy of the Third Reich? The source of the signal comes from within? ”

With his hand pushing down on the hull of the submarine, Jiang Chen retreated a short distance with the help of the reaction force, and looked at the whole picture of the submarine by the light overhead.

After all, after so many years of soaking underwater, the rust on the surface of the submarine is very serious. Fortunately, the overall structure of the submarine is still intact and should not disintegrate while exploring the interior.

At the time of falling into the trench. The submarine must have received a strong impact, judging by the appearance alone. Several dents and leaks left by the impact can be found.

Along the outside of the submarine, Jiang Chen swam to the deck of the submarine.

The barrel of the 88mm deck gun was knocked into a crooked shape. The chamber is inhabited by creatures that resemble shrimps.

Without disturbing those little guys, Jiang Chen bypassed the rotten cannon and swam directly to the entrance of the submarine.

Unfortunately, the iron gate was rusted to death.

Jiang Chen, who had no welding equipment, had to give up the iron gate and look for other entrances.

Lady Luck favored him again, and about five meters next to the submarine's torpedo launchport, Jiang Chen found a crack about one person wide.

Looking at the dark interior space, Jiang Chen swallowed and spit, took out an underwater flare from his waist and threw it in.

The orange-red glow illuminates the interior space of the submarine. After confirming that there were no dangerous sea creatures lurking in ambush, Jiang Chen swam in.

"What are these things?" Looking at those large black shipping containers, he couldn't help but mutter.

His instincts told him that there should be something terrible inside.

In addition to the containers that he didn't know what they contained, Jiang Chen also found several skeletons wearing Nazi uniforms. The skeletons lay quietly in the corners of the ship's cabin, their flesh eroded by scavengers, and the hollows of the skeletons were clogged with seaweed, looking disgusting.

For safety reasons, Jiang Chen did not immediately open the containers. Instead, he searched for the source of the signal and headed deep into the cabin.

Fortunately, when the submarine sank, the hatches were not closed, otherwise they would have been rusted to death. It's a bit of a trick.

"Is it just ahead?"

The picture on the screen of his right arm was already completely clear, and Jiang Chen's eyes were locked on the signal strength indicator at the top right of the screen, through the slight difference in signal strength. I knew that I was getting closer to that source.

"What the hell is this submarine for? Engaged in transportation? Glancing at the containers stacked along the way, Jiang Chen couldn't help but complain.

That's when it happened. He felt a jolt in his right arm, which was coming from the EP under the wetsuit.

Jiang Chen was stunned. Clicked on the screen on the right arm of the mechanical exoskeleton and switched to the interface of the EP.

[Environmental Radiation Index: 5]

Radiation? Where does the radiation come from?

Jiang Chen frowned, but he didn't take this matter to heart. Although the amphibious mechanical exoskeleton does not contain radiation protection materials, the iodine stored in the EP is still sufficient to hedge against this level of radiation. What's more, compared to the amount of radiation on the end of the world, this level of "low radiation" can be described as drizzle.

It was just that he was puzzled as to why radiation had been detected on the U-boat.

Passing through an open hatch, this was supposed to be the room where the source was located.

Jiang Chen took out a flare from his waist again and threw it to the center of the room, decorating the entire room into an orange-red world.

In the room were two large wooden boxes, the exterior of which had rotted, and one of which was even more open.

Weakening the searchlight on his helmet, Jiang Chen leaned towards the wooden box.

Inside the wooden box were five cylinders of unknown material, with the words "Japanese Army" on them. On the wall behind the wooden box are crystal clear eggs, a bit like octopus eggs, but I don't know if there is some kind of mutation under this weak radiation, these eggs are not so normal in size and shape.

"Enriched uranium? Historically, Germany should have failed to build an atomic bomb, so if so, it should be a uranium compound? Or uranium, which is not yet as pure as weapons? Floating next to the cylinder, Jiang Chen muttered to himself.

After thinking for a moment, Jiang Chen still threw these cylinders into the storage space.

As a rough estimate, the nuclear material would weigh at least 500 kilograms. It can produce radioactivity, so it should have been preliminarily purified. Although it is not clear what the market price of these things is, it should not be an exaggeration to put them on the black market and sell them for hundreds of millions of dollars.

Of course, it was impossible for Jiang Chen to take out this thing and sell it.

After destroying all those mutant octopus eggs, Jiang Chen continued to search in the room.

In the corner of the room, he finally found the source of the signal.

The black suitcase, locked.

Jiang Chen threw it into the storage space first, preparing to wait for the shore to study it later.

However, at this moment, a black shadow was projected onto the wall in front of Jiang Chen.

The alarm in his heart wrinkled, and Jiang Chen suddenly activated the propulsion of the cylinder behind him.

The high-pressure gas erupted instantly, and with the advance of the reaction force and the cover of a large number of fine bubbles, Jiang Chen rushed to another corner of the room.

Boom!

Like a hammer, a touch. The hand slammed into the bulkhead, knocking out a terrifying dent in the iron shell.

That figure is a giant octopus!

The massive body squeezed through the door, then blocked the exit.

Thinking of the octopus eggs that he mashed, Jiang Chen finally understood why this guy was so angry.

Thinking about it, this mutant octopus is the mother of those little freaks.

"it."

With a secret curse, Jiang Chen quickly pulled out the underwater pistol on his waist.

However, before they could shoot, the four touched. His hand struck like a python and clamped his limbs.

Jiang Chen's face turned red, and he moved his muscles to the limit, but the thick touch. But the hand did not move. When he was caught by a living creature, he really didn't dare to risk starting the crossing, this octopus was much larger than the lead mutant last time, and he didn't know how much energy it would take to activate all the cells in his body. He didn't want to risk overheating the bracelet and play that risky trick again.

The toxin-laden ink squirted out, but it was of little use to Jiang Chen, a human who didn't need to breathe with gills.

"Madness!"

A fierce light appeared in his pupils, and the muscles of his whole body tensed to the limit.

Jiang Chen squeezed the gun and broke the powerful touch. hand, pulling the trigger before the octopus brought its jaws all over the blade to him.

Bang!

Accompanied by several dull gunshots and strings of dense bean bubbles.

Special ammunition pierced the octopus's brain.

Blue blood floated out, blooming purple in an orange-red glow.

Without the leisure to appreciate this scene, Jiang Chen pulled the trigger and vented the killing intent in his heart.

Bound to the touch of his limbs. The hand gradually lost its strength.

It was almost as empty as the magazine was emptied, and the ferocious creature lost its breath. (To be continued......)
