Urban Hardened All-area System

In the end, Yang daoshen only gave them one day's deadline, and he will see the answers handed in by them in math class tomorrow.

At this time, Yang daoshen continued his half dead teaching, but his eyes occasionally flashed a glimmer of satisfaction.

Yehong quickly observed the topic on the paper.

This is a trigonometric function problem that ye Hong has never seen before. It is nearly ten lines long, which makes Ye Hong dizzy.

"Ding! Reading complex trigonometric function problem, experience + 1, current progress: 19100... "

" system, how much experience can we solve this problem? "

"Ding! Received host request... Scanning topic... Analysis in progress... Analysis completed.

According to the current level of the host, at least 11 points of experience are needed to solve this trigonometric problem

11 points of experience!

Well, it doesn't look like much.

Yehong immediately turned up the mathematics textbook in front of him, hoping to gain some experience.

But this kind of behavior, in the eyes of the class, is just temporary cramming.

"I'll tell you, Yehong is only good at English, not other subjects."

"The tail of the crane is the tail of the crane after all. It's no use trying to catch the duck on the shelf."

"I heard that Qin long knew many senior students in senior two and senior three. This question should not be difficult for him."

For a long time, night Hong dejectedly put down the textbook.

This high school first semester's mathematics book, has been turned over rotten by Ye Hong.

As he expected, repetition does not add experience.

Ye Hong's eyes could not help but glance at Qin long in front of the syncline, but found that he had a ready-made appearance, as if he did not put this matter in the eye.

Br >

, why does Qin long have so much confidence to solve this question than his own?

Seeing ye Hong's brow locked, Zhang Xuewei on one side said in a low voice: "ah Hong, don't worry, I believe you can!"

Hear Zhang Xuewei's voice, night Hong suddenly eyes a bright.

He said to Zhang Xuewei, "Xuewei, can you help me borrow some math books from senior two and senior three?"

"Math books for senior two and senior three?"

Zhang Xuewei was stunned and frowned. "Well... It's a little difficult for senior three, but I can try it in senior two.

It happens that one of my mother's colleagues, his son Zhao Bo, is our senior in senior two

"Ness!" Night Hong originally just casually asked, did not expect Zhang Xuewei can really get.

But Zhang Xuewei quickly asked, "ah Hong, what do you want to do with a senior two math book? Is there a way to solve the problem?

But just one day, and no teacher to teach, reading on the spot, really in time? "

Night Hong revealed a mysterious smile: "you can rest assured, mountain people have their own clever plan."

...

after school in the afternoon of the same day, at the gate of class 7 of senior two.

Qin long blocked the back door of the class as soon as he finished school.

A small figure, just want to leave quietly with the flow of people, he was quick eyed Qin long to seize.

"Stop! Run what? Will I eat you? "

Those students were immediately scared away by the ferocious Qin long, and the whole corridor was empty.

Qin long grabbed the clothes of the boy, with a pair of high glasses, rustling shrink, a look is a nerd.

He bowed his head in fear and said, "brother long, do you have any instructions?"

Qin long put the paper given by Yang daoshen into the boy's arms and said: "Zhao Bo, you are not a bully. I have a task for you.

Solve this problem for me before tomorrow, or you will break your leg!

Do you hear me? "
