Each of these rats is the length of a human forearm, and is huge, with long front teeth that bite together like a knife.

Their eyes were blood-red, glowing crimson in the darkness, like small red lamps in the darkness.

The ground was littered with white bones, some belonging to humans and others to other animals.

"Squeak-" A giant rat let out a terrible cry, and the rats immediately echoed in unison, the terrible cry echoing through the dark underground space.

They've already discovered Shen Feng and Firefly!

Immediately the rats swooped down from the dome, like a black waterfall!

Shen Feng snorted coldly, raised the shotgun, and instantly pulled the trigger.

"Boom! Rumble! Rumble! The deafening sound of gunfire echoed in the underground space, and the dense rain of steel balls directly smashed the rats that fell from the air, and the broken fur and flesh were directly nailed to the high dome, and the rat blood was like rain!

The scorching light frightened the rats, and it surged around like a tide, centered on Shen Feng and the fireflies, like a circle of black wave ripples.

It's just that the rat wave then quickly converged towards them!

That's a lot!

Shen Feng was expressionless, pushed the night vision device to his forehead, took out a bottle of gasoline from his backpack, poured it on the ground around him, and threw it on a match suddenly.

The gasoline ignited instantly, forming a protective ring of fire around the two of them.

Some of the giant rats that had just crawled through the fire ring immediately turned into fire rats, screaming and scurrying.

The fire circle temporarily blocked the rats, but Shen Feng's face became very solemn.

The number of rats is too much, and a dozen or so can be killed at most in one shot, which is a drop in the bucket compared to the thousands of rats.

And some of the rats have crawled towards the dome again, trying to pounce on the two prey from the air.

Not only are these rats huge, but they also look like they have a crazy feeling, like they have mad rat disease!

The damage done by a single rat may be limited, but when an endless number of rats pounce on them, they can gnaw people into a skeleton in the blink of an eye!

Shen Feng's eyes narrowed, his skin began to petrify rapidly, and he said in a deep voice:

"Get on my back later, let's rush out!"

Firefly also picked up a submachine gun in his hand at this time, looked at the flame and said with some concern:

"The flames will attract corpse melters, we need to get out of here as soon as possible! Close your eyes! ”

Shen Feng was stunned for a moment, and saw that Firefly had already taken off his coat, revealing a brilliant pattern, and suddenly released a scorching bright light!

The rats around Squeak ———— were burned by the bright light and retreated like a tidal wave.

Firefly immediately grabbed Shen Feng's hand and ran wildly:

"Hurry up, the bright light can temporarily shake them back!"

At this time, the fireflies are like a humanoid flashing light, and whenever the rat swarm wants to close again, a strong light immediately flashes, opening a path in the rat swarm.

"There is almost no light in the Land of Iron, and here, light is a weapon!" Firefly said loudly,

"But the light also attracts hunters in the darkness, so we need to rush to it as soon as possible! I'm running out of curse energy! ”

Was it light......

Shen Feng nodded, took out a large strong laser flashlight from his backpack, and suddenly pressed the switch.

The snow-bright pillar of light shot straight out, illuminating the road ahead as if it were day!

Many rats were immediately blinded by the bright light, plunged into instant darkness, and even began to attack each other in panic.

It's so bright, and it doesn't have the heat shooting power of Fireflies, but it's better than it lasts!

Seeing the bright flashlight in Shen Feng's hand, Firefly couldn't help but be a little stunned.

Although she had seen electric lights on the farm in the Forest of Death before, she didn't expect them to be so bright!

"Don't be in a daze, lead the way." Shen Feng hurriedly pinched her face.

Sister, you might as well have a flashlight.

The two of them ran wildly, running two platforms away, and then broke away from the rats, and then began to continue down, then forward.

Along the way, Shen Feng saw many dried bones, as well as dilapidated billboards that symbolized the once civilized and empty vending machines covered with cobwebs.

On the walls and dome of some platforms, graffiti is painted in reddish-brown paint.

Some of these graffiti are peaceful and beautiful, some are crazy and chaotic, and even have words such as "help" and "I don't want to die".

There is even a picture of childish brushwork, like a painting drawn by a kindergarten child, but the content is creepy:

A group of people gather next to an abandoned subway train and light a bonfire, and on top of the bonfire is another person!

Judging from the colors of these graffiti, it has at least a hundred years of history.

It may even be the first passengers to be trapped here after the outbreak of nuclear war.

The owners of those graffiti should have turned into white bones a long time ago, and perhaps left their descendants to thrive in this dark iron country.

In Shen Feng's world, the length of the old magic capital subway reached more than 700 kilometers.

And in this world, it is bound to be longer than 700 kilometers and the space is vast.

It could even be thousands of kilometers.

The intricate underground lines, as well as the various passage tunnels that were excavated later, together form a maze of huge underground spaces, enough to survive hundreds of thousands of people.

What made Shen Feng even more puzzled was that the tunnel here seemed to be still expanding and had never stopped.

Signs of collapse can be seen in many places, but later it is clear that they have been excavated again.

The 1.5-meter-thick concrete wall is enough to withstand the penetrating force of γ rays, while the depth of the subway system is generally about 30 meters underground.

When a nuclear explosion occurs in the city overhead, it is difficult to say whether the people in the city are lucky or those who are buried in the subway.

Although there were no more rats around, Shen Feng could hear all kinds of whispering sounds coming from a distance along the tunnel, as well as the sound of worm-like crawling footsteps, all of which became more and more numerous.

Obviously, the gunshots, fires, and lights just now made many creatures in the depths of the Iron Nation perceive that they are patrolling towards the place where they are, like sharks that have smelled blood.

"Be careful, I haven't been back for a long time, but if I'm not mistaken, the Worm Tribe is the territory of the Worm Tribe, who are good at grazing worms and cooking human flesh just as well......," Firefly whispered, "Let's sneak past the edge......"

As soon as the words fell, four or five black shadows suddenly swooped down from the surrounding dome, holding a large net woven from grass roots and tree roots, and putting Shen Feng and the fireflies in it.

On the ground in the darkness, worm herders who had been prostrate here for a long time got up, holding spears with steel spears, and surrounded Shen Feng and the fireflies.

They were short, hairless, and pale-skinned, like a pack of beasts crawling out of hell, with jerky and hoarse voices.

"Hee-hee, outsiders, food! Delicious! ”

"Kill them, kill them!"

"When you enter the Iron Country, you are in a cage and become our prey!"

The worm herders' words were chaotic and noisy, but they all smiled, and stabbed at Shen Feng and Firefly with spears in hand.

Complex stews are delicious, but simple kebabs can also taste good.
