Searching for someone in northern Myanmar, and you call that earning tuition fees?

West Campus, Lecture Hall.

On the podium, a middle-aged man with a refined demeanor and wearing gold-rimmed glasses was speaking eloquently.

His name is Wang Defa. He is a specially appointed visiting professor at the university, and his course is "Criminal Profiling in Social Psychology".

Nearly two hundred students in the audience listened with rapt attention, though some were dozing off.

The back door of the classroom creaked open, and Jiang Nanyan led two plainclothes detectives in, crouching low. She immediately spotted Su Ming and Li Changfeng sitting in the corner of the last row.

Jiang Nanyan lowered her voice and asked nervously, "How is it? Is it him?"

In the entire West Campus teaching building, only seven faculty and staff members met the condition of "not having a class during the recording." After initial investigation, five of them had clear alibis, leaving only two.

One of them is Professor Wang Defa.

Su Ming didn't even look up, his eyes fixed on the podium, and said, "Don't rush, let him write a few more words."

Jiangnan Yan was getting impatient: "What time is it?! If we wait any longer, get out of class will be over, and it'll be hard to control a large group!"

"Shut up," Li Changfeng glared at her. "Listen to Su Ming. If you say another word and disturb our school's outstanding student representative's enlightenment, I'll kick you out."

Jiangnan Yan almost choked on her breath.

Damn it, this old lecher, when did he even begin to talk about enlightenment?

Li Changfeng spoke up again: "I said, stop dawdling. As long as Su Ming says it's here, then even if there's a dog lying in the classroom, that dog is the prime suspect. We'll rush up here later. I'll lock the door, you'll show your credentials, and Su Ming will be in charge of... cough, in charge of providing technical guidance."

Following behind, Ma Da, with his hands in his pockets and gripping his gun tightly, was so nervous that his palms were sweating.

But now he is completely convinced by Su Ming. If Su Ming doesn't speak, he would rather hold the gun in his pocket until it rusts.

On the podium, Professor Wang seemed to notice something and glanced at the back row, but he didn't pay any attention, assuming they were just late students.

Just then, Su Ming suddenly stood up and walked straight toward the podium.

All eyes were on him.

"Young man, is there a question?" Professor Wang Defa stopped lecturing, smiled at Su Ming, and exuded elegance.

"Professor Wang," Su Ming walked to the podium and pointed to the area below the blackboard, "your chalk dust falls in a very regular pattern."

The entire audience erupted in uproar.

What does this mean? During the Q&A session, instead of asking academic questions, they asked about chalk dust?

Wang Defa's smile remained unchanged: "Student, is this related to our course?"

"Of course it's related." Su Ming picked up a new piece of chalk. "When you write, you apply even pressure with your index and middle fingers and lightly tap with your thumb, so the thickness of each stroke, the weight and range of the chalk dust that falls off are basically the same."

He looked down at the ground, at the few tiny, almost invisible clumps of white powder.

"But when you wrote the word 'disguise,' your hand paused for a split second, very slightly, but enough to instantly increase the pressure on your fingertips," Su Ming stated calmly. "So you see, in the chalkboard tray, right below that word, the chalk dust is piled up thicker than anywhere else. What were you thinking? Excited about your perfect disguise?"

Wang Defa's smile froze on his face.

The classroom was completely silent.

The students looked at each other, completely bewildered.

But Jiang Nanyan, Ma Da, and the others felt a chill run down their spines!

Wang Defa immediately retorted, his voice rising several decibels: "Nonsense! I was just thinking about how to phrase it!"

"Really?" Su Ming remained unmoved, his gaze shifting to Wang Defa's hand as he wiped the blackboard. "When you wiped the blackboard, you used your own handkerchief, not the blackboard eraser. After wiping, you carefully folded the handkerchief in half, with the dirty side facing in, and put it back in your pocket. This habit is very similar to that murderer who cleaned the crime scene spotlessly, not even wanting to leave a trace of his own DNA."

"That's sophistry!" Wang Defa's face began to turn pale.

Su Ming smiled.

"At 178.6 cm tall, you wear 2.5 cm shoe lifts to pretend you're over 180 cm. To correct your slight scoliosis, you always keep your back straight when you walk, which makes you look very scholarly. Unfortunately, you can't break the habit of turning your right foot out 15 degrees."

With each word Su Ming spoke, Wang Defa's expression grew increasingly grim.

Jiang Nanyan's hand was already on the gun handle at her waist. Ma Da and Li Changfeng also slowly rose and flanked from both sides.

Wang Defa suddenly roared hysterically, "Enough! What right do you have to slander a professor! Security! Where are the security guards! Throw this madman out!"

The students were completely bewildered, and some even began to blame Su Ming.

"Student, come down quickly, don't disturb the professor's class!"

"Exactly, that's so rude!"

Su Ming flicked his finger and flicked the chalk in his hand toward Professor Wang.

Snapped!

The chalk struck his smooth forehead precisely, leaving a clear white dot, right between his eyebrows.

The entire room fell silent instantly.

"Dear students," Su Ming turned around, facing the entire lecture hall. His voice wasn't loud, but it carried clearly to everyone's ears, "A true scholar, when faced with doubt, will refute it with logic and evidence. A criminal, when exposed, will only use his status and anger to cover it up."

He looked at Jiang Nanyan and mouthed "do it".

"Police! Don't move!" Jiang Nanyan shouted, flashing his badge.

Ma Da and two other detectives immediately drew their guns and surrounded the area from different directions.

The students in the front row screamed and hid in the back, and the whole classroom was in chaos.

Wang Defa's expression finally changed completely.

His refined face suddenly contorted, and his gentle eyes turned sinister and crazed.

"Someone who knows optics... so he's a student?" He chuckled softly, then suddenly kicked over the podium next to him!

Whoosh!

The heavy wooden podium slammed down on Su Ming and Jiang Nanyan!

"Protect the students!" Jiang Nanyan roared, stepping aside to block Su Ming.

In that chaotic moment, Wang Defa smashed open a window like a cheetah and jumped straight down from the second floor!

"Chase!" Ma Da roared, trying to jump after him, but Li Changfeng grabbed him.

"Idiots! Those are students!" Li Changfeng roared, "Use the main gate! Seal off the campus!"

After yelling, he looked at the calm Su Ming, his mouth agape, and after a long while, he managed to stammer out, "You son of a bitch... was that a finger flick technique just now?"

Su Ming didn't answer, but just thought to himself.

trouble.

Now, I'm completely unable to memorize the CET-6 vocabulary.
