Time always flies when you are focused.

When the melodious bell rang, the students showed awake expressions.

Almost as soon as Lao Yao shouted the words 'end of class', several figures jumped out of their seats like arrows from the string and went straight to the podium.

"Professor, I don't know much about this derivation......"

"Professor, can you use this ......instead of the Lauren formula you just mentioned?"

"Professor, why do my Lee-Mack unfolding results always differ from yours......"

Figures of different robes, genders, and grades, holding similar notebooks, showed the same, longing eyes.

It's a look that teachers can't refuse.

Professor Yao smiled with satisfaction, but did not answer their questions immediately.

"Zheng Qing, don't go yet, come over for a while. He beckoned, stopped the young public-funded student, who was halfway out of the classroom door, and dragged him back.

Zheng Qing was stunned and glanced back at several companions.

"Then let's go first. Xiao Xiao lifted his glasses, turned around and walked away neatly.

Fat Xin shrugged, hooked up with Zhang Jixin, and left behind Dr. Xiao. Zheng Qing vaguely heard him muttering "You must let him explain clearly at night...... "You don't know, I ...... last time" and other complaints.

The students who had left the classroom looked at him curiously, biting each other's ears and talking to each other, their eyes avoiding his gaze, as if he had some ulterior secret.

Jiang Yu stood at the door with a smile, tilted his head, and winked at him.

Next to her, Li Meng wrapped her arms around Liu Feifei's neck and hung almost her entire body on the body of the chief student.

"It's a nuisance. The little witch muttered, and when she saw Zheng Qing's searching gaze, she immediately slammed back viciously.

Zheng Qing smiled bitterly, made a waiting gesture to Jiang Yu, and hurried back to the classroom and came to the lectern.

"Professor, are you looking for me?" he asked in a natural tone.

"Is there anything else going on for a while?" Lao Yao asked slowly, holding the handout, holding the pipe in one hand, lowering his eyelids.

Before Zheng Qing could figure out how to answer this question tactfully, the professor simply waved his arm:

"Since it's okay, it's just right...... The results of the examination at the school hospital are out, and you can go to the office with me in a moment, and we will talk about your problems here. ”

As he spoke, he raised his right hand, curled his middle finger, and tapped his temple.

Zheng Qing opened his mouth stupidly, not knowing how to close it.

Lao Yao didn't notice the tangled expression of the public scholarship student, and he was also explaining the formulas listed on the blackboard to several studious young wizards:

“...... We often use the Taylor spell in the Lee-Mack unfold... It is a very convenient substitute for the most complex part of this derivation...... For example...... And here..."

Several young wizards gathered around the professor with their notes in their arms, poking their heads out like geese, as if they could let out a quacking sound in the next moment.

Maybe there were a little more onlookers, blocking some of the light.

Lao Yao raised his head, looked around, and found that the young public-funded student was still standing at the lectern, not listening to the lecture and not leaving.

"You can wait at the door first. He bit his pipe, waved his arm, and motioned, "I'll go out after I've told them these questions...... Up to five minutes. ”

The young public-funded student nodded silently and walked to the door of the classroom tamely.

Jiang Yu leaned against the pillar outside the door, a book spread out in his hand, and he was reading it with relish, which made people can't bear to disturb it.

Zheng Qing cleared his throat and finally caught the attention of the class leader.

"What about Li Meng?" he looked around curiously, trying to find the noisy little guy.

"I went to the library with Fei Fei... She hasn't finished Professor Emma's homework yet, and she probably won't go back until the Shushan Pavilion closes...... I can finally clean up for a while. Jiang Yu stroked the long hair beside his ears, and his eyebrows and eyes were crooked.

Zheng Qing imagined the little witch pouting, her face full of reluctance, but helplessness, and couldn't help laughing.

"I'm so sorry," he explained, looking apologetically at the witch and wringing his hands, "Old Yao...... I mean, Professor Yao, he just told me that the examination report from the university hospital has come out, and asked me to go to the office with him to discuss it...... It is estimated that it will be late...... That's why I can't go with you to study the Fa book today. ”

"Is it the last time you fainted with a headache?" Jiang Yu retracted his smile and asked with some concern.

Zheng Qing tugged at the corners of his mouth and nodded in agreement, revealing a helpless expression.

"The matter of the Fashu is not in a hurry, there are still four or five days...... We can make a new appointment. Jiang Yu comforted: "But the care of the dean of the Nine Colleges is not something that can be waited for at any time......

Zheng Qing smiled gratefully, but in the end he didn't say anything more thankful.

"It's up to you. He beat his chest and affirmed: "You determine the time and place, even if it is a sea of swords, I will not frown!"

"Forget about the sword mountain and the sea of fire. Jiang Yu's eyes bent again: "Yelena will probably be even more angry when she hears it." ”

Zheng Qing's face immediately collapsed.

......

......

It turns out that the five minutes in the teachers' mouths are very different from the five minutes in the natural sense.

Even wizards who have always been strict with time are no exception.

By the time the last student of consultation left the classroom, the sun had already set behind the ridge in the distance. Only a few burnt red fiery clouds remain, telling everyone of its former glory.

Fortunately, a professor is a professor after all.

Lao Yao did not strictly follow the normal logic of going downstairs, crossing the small square, and then turning into the office building and looking for an office like other students.

He took Zheng Qing to just turn a wall and walk down the stairs before appearing in front of a red wooden door.

Pushing open the door, it was a familiar scene.

It's still the same simple office.

The furnishings in the room were almost exactly the same as the last time Zheng Qing left, the tall glass cabinets were still tightly closed, and stacks of papers were stacked on the large mahogany desk.

If anything, it's the upholstered leather chair in front of the table.

One of the chairs was pumping some wind, lifting its soft leather cushion high to reveal a bony shelf on which a few gray-white cobwebs could be faintly seen.

But Zheng Qing's attention was not on those funny chairs.

He was still excited about the journey he had just made from the classroom to this office.

"It's amazing!" Zheng Qing exclaimed and praised: "It shouldn't even be a hundred steps...... What a day you can save by walking like this!"

"The main thing is that it also saves a lot of unnecessary trouble...... And bother. Professor Yao glanced at him with a smile: "For example, those crazy star chasers...... I heard you've recently started selling autographed photos, and if I want one, is there a discount?"

"Slander! nothing at all, sir!" Zheng Qing's face immediately turned red.

He shook his head vigorously and firmly denied the accusation.

"No preferential price?!" Lao Yao let out a lament: "What a sad thing......

"No, that's not what I meant!" Zheng Qing couldn't help but raise his voice and exclaimed.

His brain felt like it was blowing up.

"Just kidding, don't take it seriously...... Anyway, how does it feel to be a hero?" Lao Yao pulled out the chair behind the red desk, sat down hard, and raised his head and asked, "Is there anything wrong with it?"

The wide leather chair let out a satisfied sigh.

"There's nothing..."Zheng Qing answered this slightly embarrassing question vaguely, and frantically complained about the inexplicable curiosity of other people in his heart.
