Money makes the world go round.

The teacher hired by Mrs. Karina arrived early this morning and temporarily stayed at Jiraman's house.

Kasa can attend classes anytime she has time.

Not only language, but also etiquette, basic knowledge and common sense, the highly respected teacher who specializes in teaching children of aristocrats knows all about them.

Li Lin discussed with Kaisa and decided to take her to experience the customs and culture of Piltover today, and then let her go to class in the afternoon.

He could take advantage of this opportunity to add a batch of new cutting-edge technology equipment to his workshop, then create devices that could add skill points, and then unlock individual enhancement technology.

After quickly thinking of plans for the next few days, Li Lin took Kassa out of the laboratory.

They had just reached the school gate when a familiar, hoarse, middle-aged female voice caught their attention: "Excuse me...are you Mr. Li Lin?"

Li Lin turned his head and saw an old acquaintance wearing the uniform of a college professor. "Professor Zindairo?"

A few months ago, on the eve of Caitlin's coming-of-age mitzvah, the two of them visited Valentina Zindero's miniature Runeterra in Agnostic Square and had the opportunity to chat with the professor.

At that time, Caitlin felt that it was unwise for Valentina to publicly promote her invention, and asked Li Lin to ask Heimerdinger to send someone to protect her.

Li Lin did so before leaving Piltover for Shurima, and even went to see Valentina to remind her not to be too conspicuous.

She hadn't taken it too seriously at the time, but now...

"Why do you look... so haggard?"

Li Lin looked at Valentina, who was trotting towards him with her head bowed and her collar turned up to cover her face, and raised his eyebrows.

Her complexion was now dull, and her eyes were bloodshot and had dark circles under them, as if she had not slept for days, and her hair was tangled into a mess.

If it weren't for the professor's clothes, Li Lin would have thought he had seen a technician living in poverty in the southern city.

"Mr. Li Lin...you are right, you are right...I should have listened to you at the beginning..." Valentina was a little nervous and seemed to be in a very bad mental state.

According to the original world line, Valentina mysteriously disappeared when her miniature Runeterra was still a work in progress, and no one knew where she went.

Li Lin was well aware that her invention touched upon the interests of some powerful people or some desperate criminals.

Plus, she had so blatantly advertised her technology as "capable of locating every person in Runeterra," there was no way those people would let her survive.

By now, Valentina's invention was almost halfway done, and it was only a matter of time before trouble came knocking.

Even though the academy had experienced an attack that shocked the two cities, and its defenses were now very tight, and Heimerdinger had given her special instructions, she still faced personal threats.

Li Lin unfolded his mask and said, "Tell me slowly, what happened? I'll do my best to help you."

Valentina stepped forward and grasped his armored arm. "Recently... recently I've received a lot of death threats. They... threatened me to stop researching Miniature Runeterra...

"I, I've already reported this to the academy... I even called the police! But... but, the academy also has guards and law enforcement officers sent by the Piltover Police to protect me, and they... they can't find any trace of that guy at all!"

"That guy?"

"That's right!" Valentina's voice was tinged with tears. "It, it runs into my room every day and threatens me in my ear while I sleep!"

Li Lin was even more confused.

In addition to Tuchi who can use "alchemical transformation phosphorescent powder" to make himself translucent, and the Gray Lady who cannot be stopped anywhere.

He really couldn't imagine who else could bypass the guards and law enforcement officers, run into Valentina's room, threaten her, and not kill her.

Tucci is dead, and Camille only assassinates those who threaten the Philos family or threaten the stability of the Twin Cities.

Valentina's invention is not at that level, so who can achieve this level?

Shuangcheng Science Park shouldn't have this kind of guy who comes and goes without a trace and only threatens but doesn't kill.

Li Lin observed Valentina carefully without making any expression and found that her spirit was almost on the verge of collapse, and noticed something abnormal.

Then, he chose to turn on [Data-based Thinking], and Valentina's personal status was displayed on the system panel.

[Name: Valentina Zindero]

[Personal Status: Extremely exhausted, nervous (semi-collapsed), confused hallucinations...]

Chaotic illusion?

Li Lin was stunned for a moment and carefully checked the status.

[Mind-Confusion Potion: A potion created through alchemical technology that can affect a person's mind and cause hallucinations. Excessive dosage can cause permanent mental damage and has a high probability of driving a person insane.]

After two or three seconds, Li Lin came back to his senses, his brown-black pupils looking directly into Valentina's bloodshot eyes.

"Is it possible that...instead of someone invading your bedroom and threatening you, you were drugged?"
