Chapter 1

"Please claim your new player gift package."

At noon, Ling Ran saw the same line of text appear in front of him again, along with an icon shaped like a package that kept flashing in the upper right corner of his field of vision, like the flashing lights of a broken ambulance.

Ling Ran silently took out his notebook and made a note, but did not respond in any way.

As a medical student, Ling Ran had a strong sense of curiosity, but also sufficient caution and self-control.

After inexplicably and confusedly obtaining the system, the first thing Ling Ran did was to make various records and tests.

He had to first determine that he was not mentally ill.

Moreover, to avoid losing the graduation certificate that was almost in his hands, Ling Ran had to conduct the tests himself.

Ling Ran first chose the "Dawson Cognitive Bias Rating Scale," which is used to assess cognitive biases in patients with schizophrenia, especially those with delusional disorders, and it is a self-rating scale.

All 42 items are stated in the first person, describing specific attitudes and beliefs, with 1 indicating strong disagreement and 7 indicating strong agreement.

The entire scale is quite simple to complete, and some of the items are easily understood by people.

For example, item 1: "I am alert to danger."

Item 9: "I am always unsure of others' intentions."

Item 20: "I need to make sure every window is locked."

Item 25: "The first thought is always correct."

Item 27: "I do not go out after dark."

However, while the self-rating scale is easy to answer, it is somewhat complicated to process. It usually requires multiple formulas to calculate the final total score.

In addition to the cognitive bias rating scale, Ling Ran also completed a set of domestic cognitive function tests for schizophrenia, the Peter version of the delusional questionnaire, the Hoddock version of the psychiatric symptom rating scale, and the Positive and Negative Syndrome Scale (PANSS) used to determine the presence and severity of psychiatric symptoms...

In short, to judge his mental state through data, Ling Ran needed a computer with the relevant software installed.

Ling Ran silently walked to the second floor of the school laboratory, knocked on the door, and heard a quick running sound inside. A few seconds later, the door suddenly opened.

"Ling Ran, you're here." The senior sister had a light lipstick and seemed to have applied some blush. In the dim light, she easily reminded one of the wolf grandmother.

"Senior sister, I'm troubling you again." Ling Ran smiled calmly.

"It's no problem, it's a small matter." The senior sister felt comfortable all over, and a little person in her heart was shouting: "The school grass is so handsome, the school grass's smile is so cool..."

Ling Ran maintained his smile.

The senior sister suddenly came to her senses and quickly opened the door, smiling and saying, "Come in quickly, I've made tea for you... No, I'll make you a cup of tea. By the way, how is your health?"

"Hmm? It's fine, why do you ask?" Ling Ran was slightly concerned.

The senior sister, while preparing the tea bag, said, "I heard that you had a CT scan and an MRI a few days ago... I heard it by chance."

A single CT scan costs several hundred yuan, and an MRI costs around 2000 yuan. Ling Ran had to scan multiple parts, so he naturally used the resources at hand and asked the senior sister on the third floor for help.

The purpose was to determine that his brain did not have any organic lesions.

Ling Ran had already prepared his explanation and calmly said, "I wanted to write something, so I asked Senior Sister Li for help. Did you see it? How was it?"

"It looks good." The senior sister quickly corrected herself: "It's good, young and energetic, no problem."

In her heart, the senior sister blamed herself: "Why did I blurt out the chat about the MRI looking good? It's easy to be seen as a pervert, you're asking for loneliness!"

"It's good, then. Senior sister, is this the computer?" Ling Ran pretended not to notice and focused on the lab computer.

"Yes, it has SPSS 20.0 statistical software installed. As long as you have enough data, you can use our plugin to make a DSM-IV schizophrenia diagnosis. The CQB, BDI, PDI, and PSYRATS assessments you need are all fine..." When it came to her specialty, the senior sister spoke fluently.

She then patiently taught Ling Ran how to operate the software.

Every year, medical students borrow machines and software, but only Ling Ran received such meticulous guidance.

The senior sister was very happy and taught the school grass how to use the software with great care before reluctantly saying, "You can run it yourself now, I'll go out first."

She didn't want to stay and look at the patient data.

"Alright, thank you, senior sister." Ling Ran sat down without hesitation and focused on the computer screen.

The senior sister left the lab, looking back every few steps. Once the door was completely closed, Ling Ran got up, locked it from the inside, and then silently took out a thick survey form from his backpack.

This was what he had done in recent days to avoid the influence of delusional disorder or schizophrenia. He had also recorded the process and had some of it reviewed by his classmates.

For medical students, using themselves as test subjects is not uncommon, especially for mental health analysis, which doesn't require surgery or injections, so everyone likes to include themselves as test subjects.

Ling Ran followed the senior sister's instructions, inputting the numbers and letters into the corresponding plugin, reviewed them twice, and clicked "Run."

The computer started to process the data with a whirring sound.

Don't be fooled by the single-digit numbers in the form; the computational load is not small after adding formulas and coefficients.

After a long time, the printer started to make a clicking sound.

Ling Ran quickly pulled the printout over and first looked at the final result.

"Hmm... The standard value for the Dawson Cognitive Bias Rating Scale should be 128.05 ± 26.5, and I am... 154. Phew, still okay, I'm 0.55 away from being mentally ill."

Ling Ran stood up happily, about to claim the new player gift package, but then stopped.

He should find a quiet and safe place to do this, just in case the gift package contained a Transformer, which could cause trouble for the country.
