I put you in charge of the child, and you raised a monster!

The laboratory building is very clean.

There was a faint smell of disinfectant and metal instruments in the air.

Safety instructions are posted on the wall.

There is a card reader at the entrance of each laboratory.

The children all changed into small white coats.

After putting it on, Zhao Mengmeng looked like a little doctor and happily jumped around a couple of times.

Zhou Xiaoyu carefully touched the cuffs, as if afraid of wrinkling the clothes.

Chen Doudou looked down at her white coat and asked Lin Jia earnestly, "Mom, can I cook hot pot while wearing this?"

Lin Jia: "..."

Zhao Lei burst out laughing.

"DouDou, you really know how to end up working in a hot pot restaurant no matter what job you try."

Shen Ling'er glanced at Chen Doudou.

"Hot pots are not allowed in the lab."

Chen Doudou was a little disappointed: "Why?"

Shen Ling'er said calmly, "The pot will be scared by the disinfectant."

Chen Doudou: "..."

Teacher Gu was having a hard time suppressing her laughter.

The teacher from the experimental center who was in charge of reception was surnamed Zheng, and he was an associate professor in the School of Materials Science and Engineering.

Teacher Zheng looks to be in her forties, wears frameless glasses, and speaks gently yet meticulously.

He saw several children wearing white lab coats and said with a smile, "Welcome to the Materials Science Experiment Center."

"Today we will demonstrate several safety experiments."

"However, all the experiments were conducted by the teachers, and the children were only responsible for observing."

Zhao Lei nodded immediately.

"That's a good arrangement."

The director nodded in agreement.

"very good."

The assistant director watched him silently.

The director whispered, "I meant it as a compliment, not a warning."

Shen Ling'er glanced at the director.

"You're explaining too much."

director:"……"

Zhao Lei couldn't stop laughing.

"Director, now even praising someone requires a risk assessment."

Teacher Zheng first led everyone to the display stand.

On the table was an insulated bucket, a rose, and a pair of thick protective gloves.

"The first experiment was freezing flowers with liquid nitrogen."

The children's eyes widened immediately.

Zhao Mengmeng asked softly, "Will flowers turn into ice?"

Teacher Zheng smiled and nodded: "More or less."

He put on protective gloves and placed the roses into liquid nitrogen.

White mist instantly appeared.

Several children exclaimed "Wow!" at the same time.

Chen Doudou was also drawn to the scene: "It looks like smoke coming from a hot pot."

Lin Jia rubbed her forehead.

Shen Ling'er looked at the cloud of white mist and said calmly, "This cannot be eaten."

Chen Doudou immediately nodded seriously: "I know."

Zhao Lei was surprised: "You actually knew?"

Chen Doudou said seriously, "It looks too cold."

Shen Ling'er added, "It also has no fragrance."

Chen Doudou: "Yes!"

Zhao Lei: "..."

Bai Sisi laughed so hard her shoulders shook.

"The logic you two use to determine whether something is edible is quite sound."

Teacher Zheng took out the frozen roses and touched them gently.

The petals shattered instantly.

The children gasped in surprise again.

Zhao Mengmeng whispered, "It's broken."

Zhou Xiaoyu felt a pang of regret: "It's such a waste of the flowers."

Looking at the broken petals, Shen Ling'er suddenly said, "Beautiful things can also be fragile."

Teacher Zheng paused.

Zhao Lei immediately turned to look at her.

"The first lesson at the Shen Family Classroom Laboratory Branch?"

Shen Ling'er looked at him.

"This sentence is free."

Zhao Lei was taken aback: "Why?"

Shen Ling'er said calmly, "Because the flowers have already been paid for."

Zhao Lei: "..."

Bai Sisi laughed out loud.

The live chat instantly became lively.

"Hahaha, the payment has already been made!"

"Beautiful things can also be brittle; that's such a vivid image."

"She can really analyze anything just by looking at an experiment."

"Shenjia Classroom Laboratory Branch School Opens!"

"Flower: I'm broken, but I've paid the price."

Teacher Zheng nodded with a smile.

"Ling'er's words are very interesting."

"Many materials are like this; a beautiful appearance does not necessarily mean strong toughness."

Shen Ling'er nodded.

"It looks hard, but it might break easily."

Teacher Zheng's eyes flickered slightly.

"right."

Zhao Lei whispered to Bai Sisi, "Oh no, Teacher Zheng is starting to follow Teacher Ling'er's rhythm too."

Bai Sisi laughed and said, "It's hard not to go in."

The second exhibit is shape memory metal.

Teacher Zheng took out a piece of bent metal wire.

"This is called shape memory alloy."

"It can recover its original shape at a specific temperature."

After he finished speaking, he put the bent metal wire into the hot water.

Before long, the originally crooked metal wire began to slowly stretch out and eventually returned to a neat little ring.

Zhao Mengmeng's eyes lit up: "It remembers what it used to look like!"

Teacher Zheng smiled and said, "Yes, this is shape memory metal."

Chen Doudou immediately asked, "Does it remember hot pot?"

Lin Jia no longer wanted to speak.

Shen Ling'er looked at the small ring that had regained its shape and thought for a moment.

"It doesn't remember."

Teacher Zheng was taken aback: "Huh?"

Shen Ling'er said calmly, "It will go back when the temperature is right."

Teacher Zheng's eyes immediately turned serious.

"Your statement is also quite accurate."

"Its recovery is indeed related to its internal structure and temperature conditions; it's not really like a human's memory."

Zhao Lei immediately chimed in, "Teacher Ling'er has corrected the anthropomorphic expressions used in materials science!"

Shen Ling'er looked at him.

"You didn't understand."

Zhao Lei: "..."

Bai Sisi laughed so hard she touched her forehead.

"Zhao Lei, you're in charge of creating atmosphere, not understanding."

Shen Ling'er nodded.

"right."

Zhao Lei: "..."

Teacher Zheng, however, became increasingly interested.

"Ling'er, what do you think this experiment demonstrates?"

Shen Ling'er looked at the circle.

"Some things seem to have changed."

"But once the conditions are met, it will reveal its true nature."

The laboratory fell silent for a second.

Zhao Lei's smile slowly faded.

Teacher Gu was also taken aback.

That sentence sounds so much like her.

First look at the phenomena, then look at the essence.

It's not metal "remember".

The internal components haven't changed.

Even if things change, once the conditions are right, they will still come back.

Teacher Zheng paused for two seconds, then nodded seriously.

"Well said."

Zhao Lei looked at the camera and lowered his voice.

"Dear viewers, this is the second lesson at the laboratory branch school."

"Some things may seem to have changed, but given the right conditions, they will reveal their original form."

Shen Ling'er looked up.

"This sentence is chargeable."

Zhao Lei nodded immediately: "Understood, focus on paid content."

The screen was instantly flooded with comments.

"Wow, that's amazing!"

"So you've moved from discussing shape-memory metals to human nature, haven't you?"

"Shen Ling'er doesn't just memorize quotes; she interprets what she sees and makes her own understanding of it."

"The teachers in the materials science department were all stunned."

"The value of the branch campus of the laboratory is beginning to rise."

The third step is microscopic observation.

Teacher Zheng led everyone to the microscope room.

Safety samples were placed in front of each microscope in advance.

There are slices of plant leaves.

It has a metallic surface texture.

There are also fiber material structures.

The children lined up one by one to watch.

Zhao Mengmeng noticed the veins in the leaf and exclaimed in surprise, "It looks like a path."

Zhou Xiaoyu examined the fiber structure and said, "It looks like tangled threads."

Chen Doudou glanced at the object under the microscope and thought for a long time: "It looks like vermicelli."

Lin Jia: "..."

Zhao Lei laughed so hard he almost squatted down.

"DouDou, your worldview is really consistent."

Shen Ling'er finally walked to the microscope.

Teacher Zheng specially gave her a sample of a metal surface.

Under the lens, the metal surface shows fine scratches and textures.

Shen Ling'er leaned over and looked for a few seconds.

Then look up.

"It's been polished."

Teacher Zheng nodded: "Yes, this is the metal surface after polishing."

Shen Ling'er glanced at it again.

"It's not ground evenly."

Teacher Zheng was slightly taken aback.

He looked down at the sample and adjusted the microscope again.

"Where is it uneven?"

Shen Ling'er pointed to the enlarged image on the screen.

"The wiring here is messy."

"The line is short here."

"And here, it looks like the hand paused for a moment."

Teacher Zheng's expression changed.

He immediately leaned closer to the screen and began to examine it closely.

Several graduate students nearby also gathered around.

One of the graduate students whispered, "Professor, this sample does seem to have a localized over-abrasion mark."

Another graduate student frowned: "Was the polishing machine's speed not adjusted properly last time?"

Teacher Zheng did not answer immediately.

He looked at Shen Ling'er, and his gaze was clearly different.

"Little Ling'er, how did you know your hand stopped for a moment?"

Shen Ling'er said calmly, "The thread will break."

Zhao Lei: "???"

Bai Sisi was stunned: "The thread will break?"

Shen Ling'er nodded.

"When the lines are aligned, they are connected."

"When things aren't going well, it might get stuck for a bit."

"The stuck spot feels like I can't breathe."

The laboratory fell silent.

Teacher Zheng stared at the screen for a long time, then suddenly took a soft breath.

"This description... is very accurate."

"The key to judging many processing marks is to look at their continuity."

"The disruption of continuity indicates that there have been pauses, vibrations, or pressure changes during the process."

Zhao Lei was shocked when he heard this.

"So, Teacher Ling'er's sentence just now, 'The line breaks,' which, in technical terms, means the continuity is disrupted?"

Teacher Zheng nodded.

Zhao Lei slowly looked at the camera.

"Dear viewers, I hereby announce that the third lesson of the Shen Family Classroom Laboratory Branch has been upgraded to a postgraduate course."

Shen Ling'er looked at him.

"You can make an announcement even if you don't understand it?"

Zhao Lei: "..."

Bai Sisi couldn't stop laughing.

Teacher Zheng looked at the sample more and more intently.

"This sample was just delivered by the student this morning, and I haven't had time to retest it yet."

He turned to look at the graduate students behind him.

"Renumber this sample later and record the polishing parameters."

The graduate student nodded immediately.

Zhao Lei whispered to Bai Sisi, "They're here."

Bai Sisi asked, "What's here?"

Zhao Lei lowered his voice: "A regular visit has turned into a laboratory quality inspection."

Bai Sisi: "..."

The live chat exploded.

"Hahaha, a five-year-old found a problem with the lab samples!"

"The thread will break—what a genius description!"

"Teacher Zheng's expression changed."

"Wherever Shen Ling'er goes, a self-investigation begins."

Director: I knew it wouldn't be ordinary.

The director stood at the back, his expression extremely complicated.

The assistant director patted him sympathetically.

The director whispered, "I really didn't say a word."

Assistant Director: "You don't need to say anything."

director:"……"

At this moment, a graduate student nearby couldn't help but ask, "Ling'er, have you ever seen a microscope before?"

Shen Ling'er thought for a moment.

"I've seen it."

The graduate student's eyes lit up: "You've seen a lot of material samples?"

Shen Ling'er shook her head.

"I've seen the hair."

postgraduate:"……"

Zhao Lei almost burst out laughing.

"Hair?"

Shen Ling'er nodded.

"My dad said that if you magnify something small, your temper will become big."

Everyone: "..."

Teacher Zheng paused for a second, then burst out laughing.

That's quite a vivid description.

Shen Ling'er continued, "Because small problems can become big problems if magnified."

The laughter in the laboratory gradually subsided.

Teacher Zheng paused for a moment, then nodded.

"That's very true."

"Many problems in experimental research are like this."

"When it's not visible to the naked eye, we think it's nothing."

"Once you zoom in, everything comes out."

Zhao Lei immediately looked at the camera.

"Shen Family Paid Classroom Lab Branch, Lesson 4".

"Small problems, if magnified, will become big problems."

Shen Ling'er glanced at him.

"You remember it well this time."

Zhao Lei instantly perked up.

"Bonus points?"

Shen Ling'er thought for a moment.

"Secure points."

Zhao Lei nodded immediately.

"Let's just stick with the score... let's stick with the score then."

Bai Sisi said with a smile, "Zhao Lei's mindset is becoming more and more stable now."

Shen Ling'er said calmly, "Because the requirements are low."

Zhao Lei: "..."

The lab erupted in laughter again.

After a while.

Professor Zheng has already instructed the graduate students to collect that metal sample separately.

It was originally just a demonstration sample for children.

Now, after being glanced at by Shen Ling'er, it has been upgraded to experimental material that requires re-recording of parameters.

The director stood at the back, his expression complex.

He has now completely given up the struggle.

I originally thought that a university laboratory building would be a place where kids would just exclaim "Wow!" a few times and take a few cute photos.

As a result, Shen Ling'er, wearing a white lab coat and holding an account book, casually said, "The line will run out of breath," which silenced the associate professor and graduate students of the School of Materials Science and Engineering.
