Two Cities: I am building a mecha in Pi City

"I'm going, so fast?" Li Lin quickly walked to Caitlin's side, his tone was quite surprised, "How did you find out?"

"It's very simple."

She put the sniper rifle on her shoulder and reached out to pull out a strand of invisible black-gray hair from the damp wall of this fork.

"I also found similar hair from where the murderer slept. He probably noticed the law enforcement officer and accidentally rubbed it against the wall when he ran away in a hurry."

It must be you, Caitlin Sherlock Holmes Leeuwenhoek Giraman...

Li Lin couldn't help but sigh in his heart.

"Then let's move on?"

Caitlin threw away her hair and pointed at the downward sloping sewer branch in front of her.

"If we go further, we should go down to the middle level of the trench, right? I saw the sewer structure of the trench before I came here. There will be a vertical steep slope in front of it, which is difficult to walk.

"I suggest that we go back and contact Sheriff Grayson first, and ask her to send a few law enforcement teams to block the exits of this area, and then we can continue to track that guy..."

As she said that, Caitlin blinked, and a trace of doubt flashed in the depths of her pupils.

"But what makes me curious is... how could a person have hair that resembles a plague rat?"

A mouse is just as abnormal as a human being, right?

Li Lin shook his head and reminded: "Have you forgotten? The survivor's confession."

"A mouse that eats chewing gum, uses a crossbow and poison, and reads romance novels...does it really exist?"

Caitlin still couldn't understand.

"Alchemy technology allows organisms to mutate. This is not uncommon in Zaun, such as Zach."

Since meeting Zach in the laboratory before, Li Lin has told Caitlin his story.

At first, adhering to the attitude of seeing is believing, she also looked unbelieving.

How could a pool of alchemical venom become a living thing?

It wasn't until Li Lin showed her Zach's active cell tissue that she believed it...

Now, various evidences indicate that the murderer may really be a giant rat, which makes Caitlin feel very confused.

This is really a magical world...

Caitlin sighed helplessly, "Forget it, let's go back and talk about it first. There is still a witness's confession report that I haven't seen yet...be careful!"

Before she finished speaking, her face suddenly changed, and she reacted very quickly, raised her sniper rifle and shot Li Lin in the back.

In the dark space illuminated by blue-white energy bullets, a flowing green liquid flows on the top of the sewer channel.

Caitlin's reaction startled Li Lin, who quickly turned around and protected her behind him.

He thought that Tucci, who was ambushing somewhere, took the opportunity to sneak attack on them, and quickly activated the [Adaptive Defense] shield.

After a second of brief charging, a layer of light blue energy shield enveloped the two of them.

At the same time, the lighting on Li Lin's power armor dispersed the darkness in front of them, making their vision clearer.

When he noticed the dark green viscous liquid, he suddenly froze.

Wait, isn't this Twitch?

[Name: Zach]

[Race: amorphous life form]

【……】

Why is Zach here?

Damn it, Caitlin hit her teammate!

"what is that?!"

Caitlin's eyes widened when she saw the squirming green liquid.

The shot just now was just a test and didn't hit. She took aim again, her finger was tightly on the trigger, and she was about to press it.

Li Lin quickly grabbed the gun and raised it, "Wait a minute, Kate, you are one of our own, don't shoot!"

Caitlin raised her eyes and looked at Li Lin with a stunned expression, "Huh?"

"This is the Zack I told you about before."

Li Lin asked Caitlin to put away the gun, then walked up to Zach and looked up at the squirming liquid on the top.

"Hey Zach, are you okay? I'm Li Lin, I wonder if you still remember me?"

Hearing Li Lin's voice, the squirming green liquid slowly dropped down and gradually formed a head.

"Li Lin, oh! You are the benefactor of my parents, of course I will remember you!"

Zach speaks very fluently now, which is in sharp contrast to when Li Lin first met him.

He walked by squirming forward, down the curved wall.

A ball of liquid first formed legs and feet to stand firm on the ground, and then other parts of the body quickly condensed, and finally transformed into a human form again, bowing and bending over.

Due to the special characteristics of Zach's body, he can completely separate his body from other liquids.

In other words, even if he turns into a liquid and travels in the sewer sewage, he will not be contaminated by any dirt.

Caitlin from behind was stunned when she saw the scene in front of her.

Li Lin smiled and invited Zach to come to Caitlin and introduce them to each other.

"This is Zach. I told you his story before. He is a good kid."

"This is Caitlin, my love, you can trust her."

He first pointed out Zach to Caitlin, and then introduced Caitlin to Zach.

As if he was embarrassed by Li Lin's compliment, Zach opened his mouth and the tentacles on his head swayed back and forth, looking shy and happy.

"Uh...nice to meet you, Zach."

Caitlin had not yet recovered from her shock, but she still waved to Zach and said hello.

When Zach returned Caitlin's greeting, Li Lin asked curiously: "Zach, why are you here?"

“My parents asked me to spend more time helping people in need, so I came to the ditch today to help the waste pickers repair the drainage device.

"I just finished the repair and re-entered the sewer, and I felt the emotions of two people in the sewer. I thought someone was in trouble."

Zach chuckled, "I didn't expect that I would meet you again, and this Miss Caitlin."

Under the guidance of his adoptive mother Siluni, Zach has learned a lot of etiquette in the human world and speaks politely.

For a moment, Caitlin was not so resistant to this big guy who was obviously not a human being.

Li Lin nodded, and an idea suddenly flashed through his mind, "By the way, Zack, you can feel the emotions of intelligent creatures, right?"

Caitlin cast a surprised look at him and immediately guessed what he wanted to do.

"It seems like this..." Zach showed a confused expression, "But Zaun only has humans. I haven't seen other intelligent creatures, so I'm not sure."

Tucci now has an IQ comparable to that of a teenager, and naturally has emotions, and they are all negative.

Li Lin thought for a moment and continued to ask: "Then can you sense other negative emotions nearby?"

Zach closed his eyes and felt silently.

After a while, he shook his head with a regretful expression, "My perception has a limited range. The person you are talking about may be too far away from me... I'm sorry."

"No need to apologize, I'm just trying."

Under the mask, Li Lin frowned and thought for a long time.

"Then can you help me find a guy with negative emotions in the sewers? How should I say, it should be a giant rat?

"That guy has a deadly weapon in his hand. You don't need to conflict with that guy. You just need to lock its location and notify us. We will solve it later."

Zack didn't question why a giant rat had human negative emotions and lethal weapons.

He just patted his chest and said confidently: "Of course, leave this matter to me, don't worry!"

Hearing Zach's assurance, Li Lin grinned.

With the roaming jungler Zach ganking, how could a rat without support escape the encirclement and suppression of a group of them?

"By the way, we are at the oil tank factory nearby, you can find us there."

Thanks to Shuzhi and GGsbada for the reward!
