"Bell bell bell ~"

Soon, the bell rang for the end of class.

If you follow the past habits, every time the math class is finished, Lin Shiyun will always press the class for a while.

But this time, when she heard the bell ringing after class, Lin Shiyun packed up the handouts and left directly.

"Wow... I'm not dreaming! Teacher Lin actually got out of class on time today! ”

"My goodness, the sun is coming out in the west!"

"There's still a lot of time! Come... Hurry up, hurry up, go away! Let's go to the playground for a while! ”

Seeing that Lin Shiyun actually got out of class on time, the students in the class were very excited and shouted happily.

Seeing this, Ye Han's brows furrowed even deeper.....

Counting up, it has been nearly half a month since Ye Han was reborn now.

In the past half a month, Ye Han has seen and met a lot of people.

But most people are dispensable in Ye Han's eyes.....

However, there are also a few of these people, who are quite good people who make Ye Han have a good impression.

And this Lin Shiyun happens to be one of them!

You must know that after Ye Han fell off the platform, he lay in the hospital for more than a month.

In this month's time, the learning progress that has fallen behind is undoubtedly very huge.

This also means that Ye Han will definitely drag down his class grades!

Although she knew that Ye Han must be a burden, Lin Shiyun still treated him equally.

Even, he specially prepared notes for class preparation, wanting to help Ye Han catch up with the fallen course as soon as possible.

Lin Shiyun's various actions, Ye Han saw them all.

Therefore, now I see Lin Shiyun's preoccupied look.....

It is reasonable to be reasonable, Ye Han will not just sit idly by!

"Gotta figure figure out what's going on....."

Just as Ye Han was thinking about it, he inadvertently noticed the notes that Lin Shiyun had borrowed from Lin Shiyun on the table.

Seeing these notebooks, Ye Han suddenly had an idea in his heart.

Anyway, during the self-study yesterday morning, Ye Han had already read all the notes.

So now, I can just use the reason of returning notes to learn about Lin Shiyun's situation by the way.

Thinking of this, Ye Han didn't hesitate at all, picked up these preparation notes, and walked directly towards Lin Shiyun's office.

Soon, Ye Han came to the door of the teacher's office.

Standing at the door, Ye Han first knocked lightly on the door, and then strode in.

At this time, in the office, only Lin Shiyun was alone.

When Ye Han pushed the door in, he noticed that Lin Shiyun's eyes were red at this time, and he was wiping the corners of his eyes with a tissue.

Apparently, she was alone in the office and secretly crying.....

"Ye Han? Why are you here?! ”

Seeing Ye Han suddenly appear, Lin Shiyun quickly wiped her tears and asked with a somewhat flustered expression.

According to her memory, the two teachers in the same office with her were on vacation today.

And the students of Class 9, in addition to being named by themselves to talk, no one will ever take the initiative to come to them.

Therefore, Lin Shiyun really didn't expect that other people would come in at this time.....

"Teacher Lin, I have read all the preparation notes you lent me before, and I am here to return them to you."

Facing Lin Shiyun's questioning, Ye Han was very calm.

While speaking calmly, he gently placed the note on Lin Shiyun's desk.

"Well, okay I know ....."

"Wait! What did you just say?! ”

"You mean... You've read all these notes?! ”

Hearing Ye Han's answer, Lin Shiyun first subconsciously said 'um'.

But then, she immediately felt that something was wrong!

You know, these are the teacher's special lesson preparation notes, and the content recorded is very difficult!

For students, even if it's just a casual look, I'm afraid it will take three to five days!

Not to mention, you have to learn to understand the formulas and theorems!

Originally, Lin Shiyun planned to give half a year to let Ye Han make up for this knowledge.

In this way, Lin Shiyun is still worried about whether there is not enough time.....

After all, Ye Han fell behind for a whole month during his hospitalization!

And that's not just one subject, it's all subjects!

But it's only been two days, Ye Han came to return the notes, how could Lin Shiyun not be surprised?!

"Well, I've read it all."

Facing Lin Shiyun's questioning, Ye Han was extremely calm, and just replied lightly.

"Ye Han, what I said... It's not just a one-time look! ”

"Instead, all the knowledge points in the notes are 'understood', do you understand?"

Looking at Ye Han, who was calm, Lin Shiyun couldn't help but feel a little big.....

Could it be that this student's comprehension skills are so poor? Can't understand this?

"But Mr. Lin, that's the latter I just said."

"In these notebooks, I have learned all the knowledge points."

"If you don't believe me, you can test me."

Ye Han's face was as usual when he heard this, and his tone was still calm and said slowly.

Hearing Ye Han say this, Lin Shiyun couldn't help but feel a little angry.....

Now, she is already sad because of things at home, and Ye Han is still messing around at this time!

"Okay, then let me ask you, what is the induction formula for trigonometric functions?"

"What is sin (90°-α) equivalent to?"

"Also, how should the chemical reaction formula of calcium hydroxide and sodium carbonate be balanced and written?"

Lin Shiyun glared at Ye Han and asked three questions in a row.

At this time, Lin Shiyun was really annoyed!

In her opinion, Ye Han was completely messing around!

In just two days, you can make up all the courses for a whole month?

That's impossible!!

Ye Han smiled when he heard this, and said slowly: "Teacher Lin, after I answer your questions, can you also answer me a question?" ”

Hearing Ye Han's words, Lin Shiyun hesitated at first.....

But after thinking about it for a while, she nodded again and said, "Yes, as long as you can answer it, then I can answer you a question!" ”

"However, I'm your teacher, and I'm not allowed to ask those unhealthy questions!"

In the end, Lin Shiyun also specially added one!

Seeing that Lin Shiyun agreed, Ye Han showed a triumphant smile on his face.

"The first question is that the mantra is 'odd and even unchanged, and the symbol looks at the quadrant'."

"The second question, sin(90°-α) is equal to cosα."

"As for the third question.....

Speaking of this, Ye Han walked straight to Lin Shiyun's side and picked up a blue water-based pen.

Then, I brushed a little bit on the paper and wrote down a set of chemical equations very confidently and calmly.

"Teacher Lin, I've answered all your questions."

"Now, it's time for me to ask you....."

Putting down the pen in his hand, Ye Han looked at Lin Shiyun, who was in a daze, and said slowly with a chuckle.
