My skill tree increases every day.

"Brother Yu, you drive today, I'll sit in the back."

Liu Zhiyuan, wearing a baseball cap that he had dug out of some box, handed the electric scooter keys to Lin Yu.

This small electric scooter, whose number of previous owners is unknown, was inherited by the two of them from a senior classmate through joint ventures.

Male college student, used by himself/herself, 7 times used, 90% new.

Because he moved out of the dormitory and rented a small apartment near the school, Lin Yu is currently struggling financially.

"Didn't you always complain about how unsteady my driving was?"

"It's okay, Brother Yu, you drive. I don't want to drive today."

Lin Yu does ride his electric bike rather aggressively, and Liu Zhiyuan often says he feels very unsafe riding in Lin Yu's bike.

Liu Zhiyuan didn't want to either, but the thought of Lin Yu behind him, scrutinizing the back of his head, made his scalp tingle. A baseball cap alone couldn't give him any sense of security.

"Let's go, let's go, don't be late."

The old apartment the two rented was right next to the school, and they could get to the teaching building quickly by electric bike.

Because Lin Yu wasted some time before leaving home in the morning, the two of them sat down in the front row of the classroom just before class started.

This morning was English class, and the teacher, Marry, was a beautiful foreign teacher from the United States. Usually, Liu Zhiyuan would be especially excited at this time and would be particularly happy to sit in the front row.

Liu Zhiyuan quickly put the morning's events behind him, his attention completely drawn to the beautiful foreign teacher, Marry, on the podium.

Marry wore a light blue, loose-fitting knit sweater today, her long blonde hair loosely tied up, revealing her slender neck. She wore a uniquely styled grey-white necklace around her neck.

She was looking down and adjusting the multimedia equipment, her gray necklace swaying gently in front of her chest with her movements.

"Tsk, Yu-ge, look," Liu Zhiyuan nudged Lin Yu with his elbow, lowering his voice but his eyes sparkling, "Teacher Marry looks really good today, and that necklace suits her quite well."

Lin Yu followed his gaze and looked down at the gray-white necklace around Marry's neck. His eyes were drawn to it, and he watched as the necklace swayed up and down.

Um... I feel like I've seen him before?

Looking at that familiar necklace, Lin Yu suddenly felt nauseous.

This morning, Lin Yu received memories of a cult priest who used human parts to create various magical artifacts through human sacrifice.

Having gained these memories, Lin Yu can be considered a seasoned veteran with rich life experience.

So he recognized the necklace hanging on Mary's chest at a glance!

Unfortunately, that sinister thing, whose sect was unknown, happened to appear in a corner of Lin Yu's memory. Lin Yu could even see small marks, like a signature, left by the owner of those hands in his memory.

Lin Yu was certain about the raw materials of that thing.

Absolutely 100% human bones!

"I've decided," Liu Zhiyuan said, rubbing his hands together, his voice lowered, tinged with eagerness. "After class today, I'm going to talk to her. I'll start with... I'll start with her unique necklace! It'll be natural, and it'll show that we have similar tastes, right, Brother Yu?"

Lin Yu turned his head and glanced at Liu Zhiyuan. That look made Liu Zhiyuan feel a chill run down his spine for no reason.

"Are you sure?" Lin Yu's tone was calm. "I suggest you don't talk to her about that necklace."

"Huh?" Liu Zhiyuan was taken aback. "What do you mean? We're just talking about necklaces, what's wrong with that?"

Lin Yu didn't explain much, but simply turned around and opened his English textbook.

In my memory, the hands that disassembled and made those things were the hands of a man who had experienced many hardships, not the hands of a young woman like Teacher Marry.

The necklace was most likely purchased in her hometown, rather than made by her. In that case, it shouldn't cause Liu Zhiyuan any physical harm.

"Whatever you want," Lin Yu said simply in the end.

In class, unlike usual, Liu Zhiyuan was a little absent-minded, his mind preoccupied with the swaying necklace.

"Brother Yu, just tell me, what exactly is that necklace? You must know! If you tell me, it'll be easier for me to talk to her later, right?"

"Honestly, sometimes knowing too much isn't necessarily a good thing." Lin Yu really didn't want to recall those unpleasant memories, so he didn't explain it to Liu Zhiyuan.

Seeing that Lin Yu refused to speak no matter what, Liu Zhiyuan came up with a plan.

"Brother Yu, if you won't tell me, I still have the all-knowing internet!"

Liu Zhiyuan lowered his voice, quickly took out his phone, and carefully snapped a picture of Mary's necklace under the table, aiming the phone's camera at the podium.

"Wait until I get the answer, then let's see what you have to say." Liu Zhiyuan tapped his finger and uploaded the image to various online communities, asking the all-knowing netizens for their opinions.

"I met a beautiful foreign woman and I want to strike up a conversation with her about this necklace. Does anyone recognize it? I'm waiting for an answer online, it's urgent."

Lin Yu glanced at him but didn't say anything.

A few seconds later, Liu Zhiyuan's phone screen lit up, displaying various replies from netizens.

"Is the poster blind? This is clearly a bone product."

"@Old enthusiasts of antique collectibles, come out and appraise this treasure!"

"Don't ask, the answer is the root of Bodhi."

"Holy crap, wait a minute, this shape... it looks a bit like a human knuckle?"

"Add 1 to the knuckle and look at the joint surface."

"Knuckles +10086, a weakling with only anatomy background passing by..."

"It's chilling to think about. A beautiful woman wearing a human bone necklace? We've got some movie material."

"Bro, I've already thought of an opening line for you: 'Miss, are you wearing your ex's finger bone?'"

Hahahaha!

"Such white finger bones."

"Wow, that's huge... um, a finger bone?"

"Anyway, OP, go strike up a conversation! Wait for the live stream!"

"Waiting for updates! Urgent!"

Liu Zhiyuan silently turned off his phone screen.

"Brother Yu, they say that might be human bones."

"The netizens are quite knowledgeable." Lin Yu paused, then asked again, "Do you still want to talk to her? Do you share the same taste?"

"Knock knock."

A soft tapping sound came from the podium.

Liu Zhiyuan froze, thinking his little action had been discovered. He cautiously raised his eyes, only to find that it was Teacher Marry tapping the blackboard lightly with her finger, seemingly an unconscious gesture.

Her fingertips were rounded, her nails were neatly trimmed, and painted with light pink nail polish.

"Would you feel better if I told you that she didn't make it herself, and most likely bought it?"

Lin Yu gently nudged Liu Zhiyuan, who was lost in thought, and whispered something.

The hands that made that necklace clearly belonged to an older man, which didn't match Marry's delicate hands. Therefore, it was most likely just one of her special little collections.

Liu Zhiyuan then realized what was happening.

Ms. Marry is young, beautiful, and a highly educated individual; she's successful in her career and happy in her life. She just has some minor hobbies, which is understandable given our different cultural backgrounds.

How could he possibly be a psychopathic killer from some cult?

Do you still want to talk to her?

"In no mood."

Liu Zhiyuan had no other thoughts at all.

That's great, it's another way to suppress the restless hormones of a teenage boy.

Lin Yu smiled gently.

"Speaking of which, Brother Yu, how do you know so much? You can repair clocks and you know about that thing. Did we go to the same university?"

Liu Zhiyuan's enthusiasm for English class was completely ruined, so he had no choice but to start chatting with Lin Yu.

"Actually, I don't want to know so much."

"Brother Yu, you're right. I don't want to know so much either. From now on, I'll definitely read less books and newspapers, play more games, and sleep more."

Liu Zhiyuan announced it with a serious expression, as if he were establishing some great life motto.

Lin Yu was so taken aback by his sudden realization that he almost lost his composure, and the corner of his mouth twitched slightly.

No? You just wanted to do it yourself, didn't you?
