Two Cities: I am building a mecha in Pi City

Li Lin explained the reason to Hilko and revealed a little about his ambition to him. He immediately understood and nodded in agreement.

After all, after what happened a few years ago, Hilko still felt resentful towards Shangcheng.

Seeing that the people in Picheng, especially those upper-class families, were in dire straits and even lost control of the upper city, he naturally agreed with both hands and feet.

After discussing this matter, Hilko immediately asked people to select a site for the arsenal and began to collect the materials Li Lin needed.

After things were settled at the arsenal, Li Lin returned to Gila Mann's house and fished with Caitlin for a few days.

After that, he continued to study the issues of air combat robot storm and biological combat armor.

Piltover's current basic power system has only been replaced less than half, and wired telephones have just started, so the foundation is unstable.

Therefore, he temporarily shelved the research progress of communication base stations and communication satellites.

These things require a lot of time and effort, as well as human, material and financial resources.

Li Lin was going to wait until his level increased to see if it would be unlocked in the [Essence Store].

Gila Mann's restaurant.

Li Lin had just finished lunch and was going to go back to his room to take a nap and continue to improve his research in the afternoon.

But when he walked out of the restaurant just now, he met Caitlin who shouldn't be at home at this time.

"Hey, Kate? Don't you have a case today?"

Li Lin took advantage of the situation and wanted to pull Caitlin into his arms and kiss her, but she deftly dodged him and glared at her.

"Stop making trouble, mom is still inside." Caitlin reminded in a low voice, "I came back specifically to find you today."

"Looking for me?" Li Lin raised his eyebrows, noticing her hesitant expression, "Have you encountered any problems with your case?"

Caitlin smiled sweetly, "As expected of me, your detective thinking hasn't deteriorated yet."

"Compared to you, I'm still far behind. I'm not the type to do this." Li Lin shook his head helplessly.

After all, after learning from Caitlin for so long, the [Skill Panel] now has two more skills: [Basic Combat] and [Firearm Mastery].

Just as she was talking, Caitlin heard the movement in the house, waved to Li Lin, turned around and left.

"Follow me, let's go to my office. This case is special. Chief Grayson entrusted me with it."

"Piltover police?"

Li Lin frowned and thought about his familiar background.

There doesn’t seem to be any big events at this time, right?

Could it be that the butterfly effect caused by his own time-traveling caused Ionia's killer Kadar Jhin, known as the "Golden Demon", to be released by Kushuo in advance and go to Piltover to wreak havoc?

"Is this case...a serial murder case?"

Caitlin turned around in surprise, "Huh? Have you seen this?"

It's true...

Li Lin's heart sank.

Fortunately, Caitlin's subsequent explanation eliminated this idea: "It's just from the Zaun trench area... Oh, this is not the place to talk, so don't ask anymore."

She took a few steps forward, as if something suddenly occurred to her, she turned back and said, "By the way, remember to put on your power armor."

…

…

Greville Street, Caitlin's detective agency.

Li Lin, who had taken off his power armor, was sitting in Caitlin's office chair, frowning as he looked at the case file from the Law Enforcement Department given to her by Grayson.

【H.I.V.E. Incident Report】

[Case code: serial murder]

[Case Status: Unresolved]

[Investigation Specialist: Rolle, P.]

【……】

He glanced at it casually and found that the case looked inexplicably familiar, as if he had seen it before somewhere.

Before thinking too much, Caitlin came to Li Lin with two cups of freshly brewed hot tea and put down the tea cups.

She put one hand on Li Lin's shoulder and supported the desk with the other, half-bent down, her silky hair hanging down, exuding a faint violet fragrance that made him a little intoxicated.

Li Lin had no choice but to push his hair away from his face. Caitlin's unintentional teasing made him unable to concentrate.

"Kate, if you do this, I won't be interested in reading the case."

He hugged Caitlin's slender waist and gave her a little force.

With the girl's soft exclamation, she suddenly sat into Li Lin's arms.

"Stop making trouble, Li Lin~~ Serious things are more important."

There was some resentment in Caitlin's tone, but the expression on her face betrayed her true thoughts.

She still enjoyed the indiscriminate intimacy with her lover.

However, Li Lin could distinguish the seriousness of the matter, and after teasing Caitlin for a while, he stopped and continued to hold her in his arms and continue to read the detective's report.

"The incident took place at an oil tank factory that had an accident on the upper level of the ditch."

Caitlin laid out another report on the table. "Originally, this very common alchemy accident would not be reported to the Piltover Law Enforcement Department, but this incident is different."

She moved her slender green fingers and clicked on a few paragraphs in the middle of the report, "The person who made the report was the factory's private security guard, saying that several workers in the factory suddenly disappeared.

"Chief Grayson sent an investigation team to the scene and found two survivors and six bodies in a cave filled with toxic suspended particles and alchemical venom.

"Three of the corpses were mutilated and had signs of rodent bites on their bodies. They were initially determined to be plague rats that like to scavenge.

"The time of death of the two corpses was around this morning. The cause of death was an explosion in the alchemy facility. The other corpse was still warm and had just died not long ago."

Caitlin paused for a moment, then pointed to another location to report, "But that's not the point... take a look at this."

Li Lin picked up the report, looked at the place she just pointed at, and whispered: "The cause of death included acute degradation of skin tissue, corrosive liquefaction, and fatal crossbow wounds?"

The more Li Lin read, the more familiar the report became. It wasn't until he said "fatal crossbow wound" that he realized it.

This seems to be a report about the miasma rat... ah no, is it Twitch, the source of the plague?

If it is really the murderer of this serial murder, we must act quickly to get rid of it.

This guy mutated into a giant plague rat because he was contaminated with alchemical venom that was randomly discharged into the sewer.

Tucci's hatred for humans is extremely strong, and he wants to overthrow humans' rule of the world.

Although it is just its delusion, it is basically unable to communicate normally, and leaving it alone will only be a disaster.

Li Lin put down the report and raised his eyebrows slightly, "What about the confessions of the two survivors?"

Caitlin took out another confession report and handed it to him, while explaining:

"One of the survivors had part of his body liquefied by the alchemical venom. He has lost his jaw and cannot speak. He is currently undergoing treatment and is being fitted with an augmented prosthetic body."

"The other survivor was Valorie O'Landte, a wastewater analyst at the plant, but she... well, how should I put it, was overly frightened and her nerves had collapsed."

Caitlin sighed, "She actually said that they were attacked by a big rat with a crossbow, and she also threw glass bottles filled with alchemical venom at them...

"But how can a mouse still read romance novels and label bottles of collected fingers and toes with dates and moods?"

Hearing her description, Li Lin nodded secretly.

The murderer was Tucci and he didn't run away.

He glanced at the report a few more times, then dropped it on the table.

Now that we know who the target is, there is no point in looking at this thing. There is no useful information on it anyway.

But soon, another question emerged in his mind: "By the way, Kate, since the case report is so clear, why does Chief Grayson still entrust you to solve this case?"

Caitlin looked back at Li Lin and said helplessly: "According to the judgment of the investigation team, the murderer is short in size and can get into the sewers that normal adults cannot. He should be a dwarf.

"But he seemed to be aware that the investigation team was going to his hiding place, so he escaped early... He most likely fled to the middle or lower level of the trench. The investigation team's clues were broken."

"So... your case is to investigate the murderer who got into the sewer?"

Li Lin couldn't help but laugh, and Caitlin, who was speechless, rolled her eyes.

"Hmph, otherwise why would I come to you for help?"
