After reading the question, Xi Qinghuan put away his pen and raised his head, a cold voice followed, the voice of "Her train of thought ......" stopped abruptly, and the peach blossom eyes behind the glasses widened slightly, looking at Lu Zhi'an and the draft book in his hand in disbelief.

Lu Zhi'an gave ...... Shining fan!!

Thinking of Lu Zhi'an's care for Shi Ning yesterday, Xi Qinghuan was a little calm.

"I reviewed until two o'clock last night, so let her rest." Lu Shi'an said in a low voice, for fear of worrying Shi Ning, "Her thinking is very clear, her basic knowledge is more solid than me and you, her thinking is very rigorous, and she can solve problems comprehensively." And our foundation is not as solid as hers, and sometimes we are limited to fixed thinking, but we are restricted. ”

Mathematics is flexible and changeable, once the thinking is fixed, the thinking of solving the problem must also be limited, once there is a dilemma, it is equivalent to walking into a dead end, how to walk out of the fixed thinking.

Xi Qinghuan agreed, nodded slightly, and her cold voice became very light, "Well, her thinking is very flexible, and I can even give birth to another kind of thinking from her thoughts......"

As he spoke, his cold voice suddenly stopped, and his eyes suddenly looked at Shi Ning, who was asleep, and then he looked at Lu Shi'an and said, "Did she deliberately leave space for us to think?" ”

Lu Zhi'an nodded, "Well, she mentioned it in the process of solving the problem, hoping that we will have our own ideas when we look at her analysis process, rather than just blindly following her ideas." ”

Hearing this, Xi Qinghuan's face became a little complicated.

She never seems to hide her studies, she is very willing to help her classmates, and she is not worried that her classmates will surpass her because of this.

Also, with her talent, she really doesn't need to worry about being surpassed, just like he, Zhi'an and Qi Bo, never worry that the fourth place will surpass them.

The two chatted in a low voice, and discussed Shi Ning's solution to the second question together, and Lu Zhi'an did not stop his fanning wrist during the whole process, and kept sending a cool breeze to Shi Ning, who was asleep.

In the end, seeing that Xi Qinghuan couldn't stand it, he took out a homework book from his schoolbag and fanned Shi Ning with a "whoosh".

Lu Zhi'an's eyes swept lightly, "......" brother, I don't need your help at this time.

Xi Qinghuan: "......" is it wrong to share your worries for you?

With an indifferent face, he put the homework book on the stone table, and stopped helping.

After reading the analysis of the second question, Xi Qinghuan took a deep breath, and looked at Shi Ning's gaze was no longer complicated, but shocked.

Shi Ning, who changed suddenly, once again refreshed her cognition of her.

How on earth did she learn to be so powerful? I really want to know, and I want to learn from her.

Half an hour passed, Shi Ning, who was facing Lu Zhi'an, turned his posture and turned into Xi Qinghuan, who was just thinking about how to learn from her, and his eyes fell lightly with her movements, and with a casual glance, his eyes froze a little.

It's so hot that I can continue to sleep even though I sweat, and I admire her heat tolerance.

The corners of Shi Ning's forehead were already sweating slightly, and his fair face was also flushed with a little hot crimson, Xi Qinghuan finally didn't hold back, and picked up the homework book on the stone table to fan Shi Ning.

He hadn't done this kind of meticulous work, he slapped a few times, the sound was loud and crisp, and it happened that Shi Ning was almost resting, his eyes were loose, and he met Xi Qinghuan's gaze.
