Xu Jing was surprised to find that the topic had obviously changed a little more smoothly when she gave the second lecture.

Even when Jiang Lan taught her before, Xu Jing only memorized the relationship and sequence of each step more bluntly.

- After all, time is tight, and it is impossible for Jiang Lan to explain all the questions thoroughly, at most she can help her understand the formula to be used in the entrance examination.

At present, this question is the finale question, although it is only a quarter of the derivative problem for Jiang Lan, but it is obviously difficult for everyone in Class 7. Jiang Lan himself didn't expect Xu Jing to learn completely, he just wanted to get as many points as possible.

But now it's different, Xu Jing even began to have a sense of "understanding", even if someone didn't understand a certain step, she could go back and explain the reason and connection......

It's weird.

But it's so strong!

With the blessing of self-confidence, Xu Jing spoke more smoothly than at the beginning. When the first question was finished, several girls applauded excitedly.

Xu Jing herself waved her little fist happily, revealing her beautiful little white teeth when she smiled.

After reacting to it, everyone was watching, and the girl quickly stood up again, and two blushes couldn't help but float on her face.

She's so cute~ I really want to hold rua in my arms~

A few of the girls were full of aunt smiles, and they had already turned into Xu Jing's mother fans on the spot.

"Then, let's try the second question again!"

Xu Jing's expression shook the roll super seriously, and at that moment she really looked like a physics boss.

The girls gathered around her expectantly, and their heads were crowded next to the exam papers.

"Newton's second law is ...... here"

Xu Jing scratched her head, suddenly a little nervous, and forgot about it.

"I, me, me! I know! ”

When she was in a hurry, Yuan Shuo of the girls raised her hand high, "It's F = Mom!" ”

"It's F=ma!"

Wu Jiayan corrected and stepped on him.

Seeing the fight between the rivals, several girls laughed happily, and Xu Jing also smiled, forgetting the nervousness unconsciously.

"This is the place to be...... Knowing F and a, we can find m in reverse. Then ......"

The girl smoothed out her train of thought, and then continued......

Soon it was back to the place where it had just been stuck.

I have to say that it is really difficult here, even if it is not in a state of tension.

In fact, by the time you do this, you can already get 10 points for a 14-point question. Moreover, questions of this difficulty often appear at the end of the question, so there is no need to do it.

But......

Everyone came to her during their lunch break, and she didn't want them to get imperfect results.

"Don't be nervous, you can do it!"

Wu Jiayan grabbed her little thumb and whispered to her.

Xu Jing nodded vigorously.

At the same time, his head quickly replayed the powerful words that Jiang Lan had said, looking for the key to solving the problem.

[You fool]

Uh, that's not it......

The girl shook her head and changed the channel.

[The test questions are not naturally generated, but artificially arranged - therefore, no matter how difficult the questions are, there are corresponding formulas and routines......]

That's it!

Xu Jing immediately followed up quickly to retrieve the formula that Jiang Lan had taught her.

However, it is not easy to find a matching formula......

At this time, Jiang Lan came out again.

"I'll fetch water, and you continue."

He went into the water room as he spoke, and after a while he returned to his class. The others didn't care, and they all dismissed it as a vignette.

Xu Jing looked at his back, but forgot to blink like a distraction.

Tumbler ...... Milk tea...... Bubble tea shop peek-a-boo...... He ran home together...... Acceleration Formula......

"Newton's Second Law!"

“？？？ How did you come up with it? ”

Xu Jing's eyes lit up and she successfully finished the last part.

When she calculated the exact same result as the answer, Wu Jiayan was so excited that she hugged her.

"Jingbao is a fairy! I love you to death! ”

"Hmm...... Don't hold me ......"

Xu Jing was suddenly held in the arms of the little squad leader, and suddenly blushed a little and couldn't speak, and the steaming appearance of Ula Ula caused everyone to laugh.

Wu Jiayan didn't listen to her as if she bullied her, and hugged her for a long time before letting go. Now she understands Jiang Lan a little, Jingbao is so cute, she wants to bully her.

"Okay, then let's go back, or the dormitory will be closed."

Wu Jiayan waved at Xu Jing: "Then you have a good lunch break and see you in the afternoon!" ”

"See you in the afternoon! Brother Shui will be handed over to you...... Don't step on me, man! ”

"See you in the afternoon~"

Xu Jing waved softly to say goodbye to everyone, and when she heard Wu Jiayan and Yuan Shu's words, her face turned red into a small tomato.

Girls...... Oh no, it was the girls who went downstairs with Yuan Yu.

The hallway is silent again.

Xu Jing let out a long breath, her palms were sweating nervously, and the rolls in her hands were a little wrinkled.

Recalling the process just now, she quietly smiled and ran briskly towards the seventh class classroom.

"Jiang Lan!"

With her hands behind her back, she jumped into the classroom, tilting her little head.

Jiang Lan turned around: "Huh? ”

Xu Jing ran up to him, her fists clenched uncontrollably.

I was going to tell him super loudly. But when I stand in front of him, I feel nervous for some reason.

The heart is also beating disobediently.

She forgot what to say for a while, so she had to look at Jiang Lan and wink.

Jiang Lan also looked at her a little confused, blinking.

After looking at each other for a while. The girl lowered her head a little shyly, and raised it a little tentatively: "I...... I've got that out of the question. ”

When she said this, Xu Jing was a little depressed.

I still can't tell him as loudly as I imagined, and blatantly ask him to praise himself.

To her surprise, Jiang Lan's gaze was also a little surprised: "Really? ”

"Uh-huh!"

Xu Jing felt an inexplicable sense of satisfaction, and hurriedly nodded.

"Then you're pretty good."

Xu Jing was surprised and delighted: "Really, really? ”

"Of course it's true."

Jiang Lan looked at the question in her hand that was a little wrinkled, "That question is a thinking question, and I didn't expect you to really learn it at the time." But you learned, of course, very powerful. ”

"Hee-hee-hee......"

Xu Jing smirked in front of him for the first time.

I noticed that he was watching, and quickly put away his simple smile.

"Thank you."

The girl's face turned red with shame.

"Actually, I forgot how to say it at the time, if it weren't for you, I guess ......"

"I'm just going out to fetch some water."

Jiang Lan looked into her eyes calmly, "I didn't help you when you were talking about the topic, you thought about it independently." ”

"Uh-huh!"

Xu Jing nodded, the corners of her mouth rose slightly, revealing a cute smile.

Jiang Lan turned his head away this time.

For some reason, every time she smiled at herself, his heart beat uncontrollably......

"That's right! I haven't helped you get the water glass back yet! ”

As if the girl remembered something, she slapped her left hand with her right hand and ran out.

Jiang Lan stared at the door a little helplessly.

Sure enough, a few seconds later, Xu Jing ran back in a little anxious.

"The water cup, the water cup is missing......"

Jiang Lan picked up the water cup and shook it at her: "Because I just went out to get it myself." ”

Hmm, I see......

The girl habitually put her finger to her lips and nodded.

Jiang Lan looked at her innocent appearance, wanting to stop talking, stopping and wanting to speak.

"And what about your own kettle?"

"Alas, alas? I forgot! ”

The girl hurriedly ran out again.

Then he came back dejectedly and looked at Jiang Lan aggrievedly.

"My kettle is gone......"

“…… Because I got it back for you. ”

The girl was stunned for a moment, and sure enough, she saw that the small kettle was already full of water, and it was on her table.

It's so conspicuous that it's invisible......

Not...... So Jiang Lan just said that he was fetching water, was he actually helping her fetch water......

"Bang"

Before the girl could finish it, she was blown up by Jiang Lan.

"Han Bao."

Xu Jing covered her head aggrievedly: "But you just said that I am very powerful......"

"That's a great bun."

Jiang Lan yawned and continued to catch up on sleep with his arms on his pillow.

Xu Jing quietly puffed out at him.

The eyeballs flickered and bent into two crescents.

I deceived my brain again.
