Ark 21, sewer.

Several ragged and unkempt workers were busy, unblocking the blocked sewer.

Two people jumped into the sewage to do their work.

A few people were left on the shore, guarding a worn-out machine.

An old man was chatting to others.

"I heard from my grandfather that the sun suddenly started to grow bigger and turned red early... What's the red one..."

"Red superstar."

The youngest, 15 or 6-year-old boy responded.

The old man patted his thigh and said:

"Yes, yes, red giants, the sun is getting bigger and bigger every day, and in less than a month, it swallowed Mercury and Venus."

"The next one is our earth?" the boy asked.

"That's not. It was then that black fog appeared and wrapped around the earth, which saved us humans." The old man said.

Several young people around were upset and immediately refuted.

"The black fog is clearly going to devour us humans. It is the real God's punishment for us. How could it save us?!"

"That's right, if it weren't for the black fog, we wouldn't have to hide in the city."

"My parents are dead at the hands of monsters!"

Several young people were emotionally excited.

The youngest boy remained silent.

At this moment, two people who went into the water floated out and shouted:

"Open the machine!"

The old man stood up and kicked the machine switch.

The machine at one person's height roared, causing the steel cable to vibrate and unblocked the blocked sewer.

The machinery only roared twice, and the flag was stopped.

The alarm light flashes red.

Circuit interruption.

The old man cursed and said to the young man:

"Bai Ya, go to the power distribution room to check."

The white crow was bowing his head and pondering.

Hearing the old man's order, he responded and went to the distribution room.

Walking in the dark sewer.

He was still thinking about the old man's words.

The 9th day of traveling.

He did not obtain the memory of this orphan, and could only obtain information about the world through indirect touch.

This is still the earth, but it is a wasteland.

Things called black fog are raging on the surface, devouring living bodies. There are all kinds of strange and absurd monsters in the black fog, and humans are concentrated in many big cities.

The city he lives in is called Ark.

This is a three-dimensional city, which is said to have a height of more than 2 kilometers and is divided into countless layers of operation.

Information is heard and he cannot verify the authenticity.

This body grew up in an orphanage and is now a pariah. Not long ago, he was sent to the XSD2 repair station in District 21 to be responsible for the maintenance work on the bottom floor of the ark.

In the Ark, only the upper town can see the sky and the sun.

Middle, the lower city area is closed and there is no difference from the underground.

Narrow, dark, wet.

All the eyes are rusty metal walls.

As the lowest class, the untouchables have no choice, their situation is similar to slaves, and they don’t even have personal property. Normally, they will work until they die at work and will never see the sun in their lifetime.

Bai Ya naturally does not accept the status quo.

He is trying to figure out the situation in this world and try to find ways to get out of the status quo.

At least, you must live like an individual.

Come to the distribution station.

Check the line.

The plug is old and falls off, causing the machine to be unable to supply power.

Relink the plug.

Bai Ya found that due to aging problems, the plug would slide out, so he simply stepped on the plug to keep the machine powered.

The other end does not need his help.

This body is 15 years old and is in a state of malnutrition for a long time. Her physical fitness is very poor. She will have to breathe at all when she goes away. Her strength is too weak.

On the other side.

The machinery begins to operate.

The blocked sewage channel was cleared again and the stagnant sewage began to flow.

The workers cheered, packed up and prepared to go back.

Just then.

Slight vibration on the ground.

Everyone stopped what they were doing and looked at the sewer entrance.

That's the direction of the vibration.

The water flow became turbulent and the vibration became stronger.

There was a loud bang.

The black torrent burst out.

In this black torrent, there are countless small red glowing dots that move quickly with the torrent.

Take a closer look.

It turned out to be countless black rats.

These mice are the size of domestic cats, with red eyes, one by one, densely packed, condensed into a black tide, spraying out of the pipes, rolling like waves with sewage.

The old man reacted first and shouted in horror:

"It's a group of shocked rats, run!"

Several workers were shocked and left their things behind, turned around and ran away.

But after taking a few steps, he was caught up by the Black Tide.

The powerful impact force drove several people away.

They rolled with the dark tide, as if butter was rolled into an iron pan. Their bodies were torn and broken, rolled and shrunk, and disappeared completely within a few seconds, and there was no bone residue left.

The dark tide is still surging, spreading along the sewer.

Indoor distribution room.

Bai Ya looked down at his shadow.

Under the dim lights of the distribution room, his shadow was twisting.

There was a faint red light flashing in the eyes.

As a time traveler, he has golden fingers.

His shadow can be separated from the concept of shadow and become an existence outside of independent light, able to interact with entities, transform freely, like a slime. He can link and perceive with shadows, just like an extra limb.

No matter how you look at this, this ability that has a tendency to be a book, has temporarily become a burden to him.

Because shadows consume energy.

Even if he doesn't use his abilities, his appetite will double.

As a pariah, food is scarce.

The situation is getting worse now.

The white crow is so hungry that his eyes are blurred every day.
