As early as the end of the last century.

The sewage and wastewater treatment systems in most cities have basically achieved fully automated management.

Even the worst small cities in the 18th tier have basically realized the semi-automation process.

In other words, there are only sewage pipes and a large number of filtration systems in the sewage treatment station.

There is basically no human words.

The security guard at the door can be regarded as a few employees.

When Irin and Oda Mai approached, the iron gate of the sewage treatment station was locked.

The professional security guard is still dozing off.

Yi Lin narrowed her eyes, looked from afar, and said with a pity: "It seems that the possibility that this is a leech's nest can be basically ruled out."

It's indeed a bit regretful.

Oda Mai slowly blew a question mark.

She couldn't quite understand Yi Lin's whisper.

In fact, the whole confusing case, in Oda Mai's thinking, only the most fundamental two points and one line are left after simplification:

There is a bad guy who should be cut.

Find it out and hack it to death.

Kill to death alive.

This pure and ultimate thinking pattern is actually not without its benefits.

Any hesitation will affect the speed of Oda Mai's wielding knife.

At least since Yilin met Oda Mai, this woman's sword skills have become more and more terrifying.

Even if she does not have the identity of an apostle, an ordinary new apostle might not be able to get close to Oda Mai within three meters.

After talking to himself, Irin was too lazy to explain to Oda Mai.

No need.

After checking the complete structure of the sewage channel in Cangyang City, he once suspected that the leech-laying nests of leechs would be in this sewage treatment station.

But when Yi Lin saw that the security guard at the door was alive, she basically ruled out this possibility.

The reason is very simple.

This security guard who works alone here is the best "food" to start, no doubt.

Judging from the leech's style tonight, he does not seem to have the good moral character of "rabbits do not eat grass beside their nests".

"You wait at the door, I'll go in and take a look."

Yi Lin looked back at Oda Mai and prepared to activate the skill to sneak in.

“No need.”

Oda Mai said with a silence, then walked towards the security booth with a knife, lifted up her legs, kicked her leather shoes, and kicked the door lock.

"Crazy--"

The security guard had just woken up, but Oda Mai was moving faster, and she cut the security guard's neck with a knife...

"alright."

Oda Mai seemed to have done something insignificant, without any turmoil, walked in and out in an ordinary manner.

Looking at the poor security guard who was foaming at his mouth and lying limp on the ground, Yi Lin silently gave a thumbs up to Miss Oda Mai.

This method of infiltration is considered straightforward and rough.

As long as no one else sees it, it is perfect stealth.

This place is not a secret place. To put it bluntly, it is a place where even the thieves are too lazy to think about. The monitoring equipment only covers some important areas. After Irin cut off the power supply of the monitoring equipment in a familiar way, she and Oda Mai walked into the sewage treatment station with a swagger.

As for the processing method of the entrance...

Click.

Oda Mai Chang's sword is sheathed.

Yi Lin rubbed her painful eyebrows.

He always felt that if this continues, Oda Mai would have to cut a hole in the world one day.

Twenty minutes later.

Yilin: "I'm fine."

Oda Mai: "That's it?"

She seemed very unhappy.

The prelude to the temporary decision made her excited, thinking that something big was going to happen.

Now that he was full of desire to cut people down, he was forced to hold back, making Oda Mai's dissatisfaction written on his face.

The air at night is cool and humid.

Irin and Oda Mai walked all the way, with a lot of night dew hanging on their hair.

"It seems to be raining."

Yi Lin looked up at the sky and felt that the climate seemed to be something wrong these days.

After humans lose their satellites, they can no longer accurately predict weather changes.

All depends on experience.

Oda Mai silently put her hand on the knife handle.

"To be honest, at the end of this matter, I really don't want you to shoot."

Yi Lin took a few steps back, but couldn't help but sigh and said the truth:

"Don't look at me with this kind of eyes. Because by then, it means that the whole thing has escalated to the point where no one can stop it."

...

...

It's exactly two o'clock in the morning.

When Yi Lin returned to the center of Cangyang City, Yuan Zhiye, Wang Bing and others all had solemn expressions.

Gu Tianqing smiled with a smirk, sitting in her seat, wearing black gloves, and leisurely brewing tea, which formed a sharp contrast with the tension of others.

Without Yuan Zhiye's words, Yi Lin guessed roughly why this was.

"How many people have died."

Yi Lin asked.

Yuan Zhiye smiled bitterly: "The eleven dead people in front are considered drizzling. So far tonight, there are twenty-three victims who can be found."

In his words, he used a premise.

That is the "deceased who can be discovered".

In other words, those who died alone at home and had not had time to be discovered will not be counted.

In other words, the death toll is rising wildly with a terrible number.

Leeder... Killing crazy!

He was manipulating his leech army and hunting ordinary people wildly throughout the entire Cangyang City.

This city with a population of millions has become his hunting ground.

"Come on, have a cup of tea."

Gu Tianqing was not panicked, so she made a cup of tea for each person, and said with a smile: "If I were a leech, it would be time to stop at this time. But why?"

Yi Lin glanced at Gu Tianqing.

Others may not have tasted the profound meaning of Gu Tianqing's words.

But Yi Lin understood as soon as he heard it.

This is not something that can be in harmony.

It is the "motive" issue that Yi Lin was still thinking about not long ago.

Logically speaking, even some apostles with paranoid personality will follow a principle when they kill in reality.

That's low-key.

If you add another principle, it is safety.

The special group is like the official organization of the apostles in reality. Anyway, ordinary apostles will care about the official power of the special group.

But the strange thing about this case is here.
