In the living room, Valentina made a pot of tea for Li Lin and Kasa.

It would take Caitlin some time to get from Greenwell Street to the academy.

During this period, Li Lin asked about Valentina's recent situation.

Since she introduced her invention to people in Agnostic Square a few months ago, many families have shown interest in this project and are discussing investment.

However, Valentina has always believed that this kind of dangerous technology cannot be applied to ordinary life and cannot be mastered by those Piltover families.

She is only prepared to cooperate with the Piltover Police, and her use must be approved by the Council.

She was first harassed more than three months ago.

At that time, several Zaun thugs with alchemical technology-enhanced prosthetic bodies came to the door and said they wanted to borrow some money.

But not long after, the law enforcement officer on night patrol happened to arrive at her house, and the group of thugs fled at the sound, not daring to stay any longer.

Valentina thought they were just ordinary robbers, just a little too blatant, so she didn't take them seriously.

It was in the following weeks that she gradually realized something was wrong.

Every day, animals that died in various ways would appear in her yard, from ordinary cats and dogs to shadow rabbits, plague rats, and even stone beetles and young magic frogs.

Valentina called the police, but when the law enforcement officers came to investigate, they concluded that it was just some slum kid's prank.

It wasn't until the first death threat arrived that she finally realized the seriousness of the problem.

Because she rarely interacts with others and her family members are no longer around, Valentina chooses to ask Heimerdinger for help and applies to live in the academy.

But things didn't stop there.

She still felt that the world was unreal, and that there was always some terrifying existence staring at her in those dark corners.

In the following weeks, the situation intensified. She began to feel that someone was whispering threats in her ears every day, and there was also an inexplicable ringing of the phone in her ears...

Valentina became more and more excited as she spoke, as if these memories had aroused the fear deep in her heart, and her whole body began to tremble uncontrollably again.

"This is just an illusion, Valentina, calm down!" Li Lin quickly comforted her.

Then he stood up and opened the window, letting the five storm robots that had just arrived fly into the house.

Valentina was stunned. "...What is this?"

"The combat robots I developed are called Air Combat Mechanic Storm. They have semi-intelligent auxiliary chips that can automatically identify enemies.

"Wait for Caitlin to find the clues later. We will help you deal with the mastermind behind your threat. Don't worry when we leave. They will protect your safety."

As soon as Li Lin finished speaking, there was a knock on the apartment door. It was Caitlin.

He stood up and opened the door. Caitlin, wearing a tight-fitting combat suit and a maroon beret, was standing in the corridor, carrying a suitcase containing an Iron Blood sniper rifle.

She heard a familiar sound, and her attention was drawn to the Storm Robot floating in the house. Her eyebrows frowned slightly, "It seems that the situation is serious?"

"Well... let's go inside and talk."

Li Lin first moved sideways to give Caitlin enough space to enter the house.

Then he glanced left and right at the corridor from the door.

The law enforcement officers still stayed at their posts and nothing seemed to be wrong.

Li Lin did not take it lightly. He controlled a storm robot to guard outside the door and then locked the door.

Among these law enforcement officers, there might be undercover agents sent by the family behind the scenes, so we must not let them know about the following conversation.

Gu Du

Looking back, Caitlin had already taken out her notebook and was asking all kinds of detailed questions, even down to what she had eaten for three meals a day, who she had met recently, whether she had received any new threatening letters, etc.

It was difficult to explain clearly over the phone, and there was a possibility that it would be monitored by people planted by the mastermind, so Li Lin didn't say much.

After Caitlin finished asking questions, she began to carefully check inside and outside each room, and finally stopped by the trash can in the living room and knelt on one knee.

"Did you find anything?"

Li Lin walked over and was stunned when he saw her digging out a few scraps of paper from the full trash can.

The [Digital Thinking] panel in his mind showed that there were remnants of "Mind Confusion Potion" on these scraps of paper.

"Trash can...why didn't I think of that? Those guys actually smeared the potion on the letter."

Caitlin turned around in surprise, "Potion?"

Valentina mentioned this matter just now, but her thoughts were confused and she couldn't explain it clearly.

"It's an alchemical potion that can cause hallucinations. If taken in excess, it can cause irreversible damage to the mind, or even death," Li Lin explained.

"The fact that it can be applied to a letter means that this agent can affect people through the vapors it produces. Valentina said she's read every threatening letter."

Caitlin lowered her eyes and pondered for a moment. "Her condition is already very serious. She should have started inhaling the drug you mentioned when she received the first threatening letter..."

She took out a transparent evidence bag from her small shoulder bag, put all the torn pieces of threatening paper into it, and carefully put it back into the shoulder bag.

These pieces of paper stained with alchemical residue are evidence and must be kept safe.

Then, Caitlin stood up and looked at Li Lin, "Based on the current clues, this matter should be related to a certain alchemist baron in the bottom city."

Today, all the alchemy barons except Renata are subservient to Hillco, but that does not mean they will listen to him in everything.
