Inside the sewage tunnel beneath the city.

"Beep~beep~."

"Squeak~squeak~!"

In the dark, humid environment, there are occasional sounds of water droplets falling, and subtle movements caused by rats competing for territory.

There is turbid sewage flowing in the center of the tunnel, and on both sides are narrow walkways that are above the water level to facilitate workers to clear blockages and repairs, and the angle between the walkways and the walls is covered with green moss.

?

Suddenly, two rats biting each other on the right side of the road stopped at the same time, as if they had discovered something, and turned to look at the corner at the end of the tunnel.

The corners of their mouths and beards twitched and they were stunned for a few seconds before they saw a figure passing around the corner.

!

After discovering that it was a human being, the two mice immediately "resolved their suspicions" and ran away. By the time the man and his companions walked around the corner and came to the sidewalk on this side, they had already lost sight of them.

And that person is Leon, who has blond hair parted, wears a "transparent mask" with a faint blue light emitting from the edge, and holds a customized laser pistol.

The companion following him was Ada, who was wearing the same "mask" and holding a smaller pistol.

The so-called "mask" is a disposable filter that has the function of holographic glasses and is exclusive to intelligence agents.

With the large number of nanorobots in their bodies, Leon and Ada basically don't have to worry about being infected by microorganisms.

The tunnel the two of them were in was the underground sewage tunnel in Area 04 of Arcadia City.

As for rodents like rats, wherever humans live for a long time, they will appear soon no matter where they are.

At this time, Leon and Ada continued to go deep into Area 04 according to the route guidance displayed in the upper right corner of the mask, rushing to the area where the vomiting worker had been.

The two of them kept silent and moved forward steadily, passing through a downhill slope and arriving further away from the surface.

"Whoa! Whoa!"

Suddenly, Leon heard some kind of animal in front of him, like dirty sewage flowing, running quickly towards the path where they were.

Leon glanced at the upper left corner of the mask screen, which showed that the straight-line distance between him and Ada was 24 meters, and the local time was 22:31.

During this period, theoretically no workers will be on duty or inspecting the sewage tunnel.

Seeing this, Leon turned to look at Ada behind him.

"..." The two nodded silently.

Then Leon jumped over the sewage, easily jumped to the opposite sidewalk, and separated himself from Ada.

Immediately afterwards, the two men raised their pistols and pointed them at the "T" corner at the front, concentrating on waiting for the "animal" to appear.

"Wow! Wow!" The sound of dripping water became more and more obvious.

"Huh...huh..." The two of them also controlled their breathing intervals more and more to maintain the best shooting condition.

Finally, the figure of the "animal" appeared in their sight...

But the barking of "Woof!" completely broke the tense and solemn atmosphere.

It turned out to be a stray dog ​​with dirty hair and medium size, running back and forth in the water and playing.

Perhaps because he was too focused on playing and the sewage masked the smell, when he saw Leon and Ada, the stray dog ​​discovered that there were actually humans coming to the "territory" it often visited at this time.

So it bared its teeth and barked, then turned and ran away.

"Haha..." Looking at the stray dog ​​running away, Leon lowered his gun and laughed at himself: "I didn't expect the two of us to almost fight a dog."

"But this also shows that there is nothing too abnormal nearby, right?" Ada also said with a chuckle.

"That's right... let's go."

"good."

The two of them ended their conversation and headed down together again.

When they arrived at the area 45 meters above the surface where the previous group of workers had been, they finally discovered something unusual.

This is an automatic recycling plant responsible for treating sewage.

But in the outer tunnel where the two of them were, the sewage almost stopped flowing, turning green and yellow in color, similar to the worker's vomit.

Even if you don't take off the mask, you can guess how disgusting the smell will be just by looking at this place.

"Um..."

Ada squatted half-crouched on the edge of the street, observing the sewage situation at close range, then looked at the closed gate in front, groaned, and said to Leon who was standing next to her:

"Lyon, those workers must have just repaired this place today."

"right."

Leon, who was also looking at the gate, responded lightly, but what he was staring at was the surveillance camera installed above the gate.

Moreover, after his line of sight marked the surveillance camera, the screen of his mask was scanned and the result was "Damaged".

After getting this information, Leon reached out and patted Ada's right shoulder, signaling her to get up quickly and be on guard, and said in a lowered voice:

"It seems that someone deliberately destroyed the repair results of the workers, gradually paralyzed District 04, and even the underground system of the entire city, and then tried to spread some kind of virus or bacteria, or even microbial weapons."

Hear the words.

Ada stood up solemnly, held the pistol, followed Leon, and slowly walked to the end of the street where they were, approaching the automatic door that led to the interior of the factory.

Come to the door.

The automatic door is tightly closed, and the terminal screen on the right wall also displays a red light, indicating that the automatic door has also been manually locked.

Seeing what he saw before him, Leon became more convinced of the abnormal events facing Arcadia, leaning towards his previous speculation.

So Leon waved his left hand to Ada, signaling her to be alert to the surrounding environment and help cover her.

Leon took out the intelligence officer's exclusive mobile phone, uploaded the latest discovered intelligence, and notified the Krieger 087 Regiment stationed in the northernmost part of the city, so that the 087 Regiment could be prepared for possible battles.

After completing the operation of uploading the intelligence and notifying the 087th Group, Leon put his mobile phone next to the terminal and started cracking the automatic door.

In less than ten seconds, the screen of the terminal changed from red to green, indicating that the mobile phone successfully unlocked the automatic door.

Seeing that everything was going well, Leon took back his phone, but his expression behind the mask became more solemn. Then he looked behind him with his peripheral vision and reminded:

"Ada, the situation in the factory is unknown, so for the next actions, we will try our best to continue to obtain intelligence without exposing ourselves, and the degree of danger is also unknown, so be mentally prepared."

"Don't worry." Ada raised her hand to gently lift her scattered bangs, and said with a calm and confident smile to Leon:

"We've been partners for decades, what kind of anomalies have we never seen before? Open the door, rookie."

"yes."

Affected by Ada's words, Leon also sighed with a smile. Without hesitation, he made a fist with his right hand and touched the screen of the terminal hard.

"Shua-."

With the sound of the automatic door opening, the two men grasped their respective firearms and entered the factory unimpeded.

The inner walkway is narrower, but the structure separated from the drainage channel means that they don't have to worry about the possibility of falling into the sewage.

When passing by a sidewalk with large observation windows on both sides, they found that the sewage pool below the window was even more turbid.

Such a putrid environment attracted a large number of mosquitoes to hover around, and the walls of the pool were covered with densely packed tiny, white insect egg sheaths.

Even the pavement next to the sewage pond began to have a large number of holes, like fungi, plants... or organisms that carrion.

Leon and Ada, who were squatting behind the window, took a closer look and saw a rotten creature that looked like a "fish", but was covered in pustules and wriggling tentacles, swimming in the turbid sewage.

Coupled with the "fungi" that had countless flying insects coming in and out, even the two experienced people felt the urge to vomit after witnessing this.

The two of them endured the discomfort and got up and continued moving forward, leaving this road that had a bit too much visual impact.

The two people walking through the factory also discovered that all the machines that filter sewage in the factory were out of operation, and many areas still had traces of cleaning.

at last.

The two of them passed through the entire factory unimpeded and came to the exit at the end, in front of an automatic door with the words "leading to a large drainage channel" above it.

Leon repeated the steps to crack the terminal, and while waiting, he said to Ada: "Carry out maintenance work in such an environment, otherwise the guy in the bar will be so seriously ill."

Ada nodded in response and said: "Lyon, the pollution down there is so serious, it's impossible that the top management in Area 04 doesn't know about it."

"You mean..." Leon turned to face Ada and said, "There is a problem with the top management in District 04?"

"This possibility cannot be ruled out." Ada expressed her speculation:

"Arcadia is far away from the center of humanity, and communications will be delayed to varying degrees due to fluctuations in the fault space. The company and UEG cannot monitor the situation here immediately.

Once the Sheriff's Department prepares for a large-scale investigation, the number of disappearances and deaths decreases very quickly, and combined with everything we just saw, everything can be sorted out."

"Well, you're right."

Leon, who agreed with Ada's point of view, saw that the terminal screen turned green, so he used his mobile phone to upload information about possible problems to the top management of Area 04 to the company and the Krieger 087 Group.

After getting ready.

The two opened the automatic door and walked out of the factory into a wider tunnel.

Moreover, due to the shutdown of the factory, the water level of the sewage is significantly lower than that of the tunnel above.
To be continued...
