The weather gradually turned colder, and the afternoon sun shone on Wu Xiu through the window, and he felt warm and very comfortable.

In order to better match the atmosphere of the library, Wu Xiu deliberately picked up the book and read it.

However, because Wu Xiu was holding a book related to mechanical mechanics, he couldn't understand it at all.

It didn't take long for Wu Xiu to feel sleepiness coming, and he slowly closed his eyes.

Wu Xiu was woken up by Qi Wenhua, and when he saw that Qi Wenhua had done a good job, he praised: "He is worthy of being a scholar, excellent!"

"No, it's mainly because the teacher teaches well. Qi Wenhua habitually said modestly.

“——”

"Because tomorrow all three of us will go to the podium, and the old dean will let everyone speak. For the sake of safety, I used three methods to solve this problem, you two each pick one that can be remembered, let's each use one method to explain, and there will be no problem at that time. As he spoke, Qi Wenhua opened the notebook, and there were three ways to solve the problem densely written on it.

Ni Nan quickly chose a method, and Wu Xiu looked at it for a while, as if a heavenly book was in front of him, he really couldn't read it, let alone remember it.

However, in order to cope with tomorrow's class, Wu Xiu still worked hard to memorize the problem solving method.

Finally, it's time for engineering mechanics class.

According to the process, Qi Wenhua wrote the question on the blackboard before class.

After class, Qi Baoping walked into the classroom and stretched out his hand to signal, and Qi Wenhua began to explain. He had a confident expression on his face, and his speech was full of energy, which made Qi Baoping next to him nod his head and praise constantly.

After Qi Wenhua finished explaining, Ni Nan began to solve the problem in another way. Although Ni Nan stumbled, fortunately he finished it completely.

In the end, it was Wu Xiu's turn to come to the stage, he saw Qi Baoping's serious expression, and then looked at the curious looks of the students under the podium, and suddenly felt a little overwhelmed, and he finally memorized a general solution to the problem, and instantly forgot all about it.

"Say, what do you think of this question?" Qi Baoping smiled gently.

Wu Xiu really couldn't think of the third method, so he gritted his teeth and said, "This question involves a wide range of knowledge, and it just incorporates a lot of knowledge points that we have learned recently.

Qi Wenhua's solution is clear, reasonable, and well-founded, while Ni Nan's solution is concise and clear, and both sides have their own merits, obviously accumulating knowledge in ordinary times. ”

After Wu Xiu finished speaking, the classroom was silent, including Qi Wenhua and Ni Nan, who were stunned, and they didn't seem to react.

Isn't it time to talk about the topic? How do you make a summary?

"Then after listening to Wu Xiu's words, is there anything else you want to ask?" Qi Baoping broke the silence at this time.

Wu Xiu's heart instantly became nervous, if someone asked him at this moment, he would "hang" on the podium.

Qi Baoping was equal for a while, and seeing that no one spoke, he looked at Wu Xiu and said with a smile: "You are right, Qi Wenhua and Ni Nan solved this problem in two different ways, but do you know, in fact, there is a third solution to this problem." ”

Wu Xiu naturally knew that it was what he should really talk about, but because he had forgotten, he could only pretend to be puzzled and shook his head, and said in surprise: "There is a third solution?"

"Hmm!" Qi Baoping was very satisfied with Wu Xiu's expression full of curiosity, he nodded, and explained: "Reverse reasoning method! Of course, this requires you to have enough knowledge and reaction ability......

Watching Qi Baoping talk endlessly about the same third method of solving the problem as Qi Wenhua left for him, Wu Xiu was once again deeply impressed by Qi Wenhua's learning ability.

Seeing Wu Xiu's expression, he was first surprised, then admired, and Qi Baoping spoke more energetically.

"Oh, this method is really good, why didn't I think of it?" Wu Xiu shook his head pretending to be helpless.

"Learning is not about resting on our laurels, we need to be flexible in solving problems, and we must learn to think more from other perspectives. ”

"Well, got it. Wu Xiu said very respectfully.

"Alright, you three go back to your seats! Now, let's start today's lesson......"

Whew-

Wu Xiu secretly breathed a sigh of relief, today's "hurdle" has finally passed.

"Brother Xiu, it's amazing! Qi Wenhua said with admiration.

"Well, if I had known, I wouldn't have had to make so much effort to memorize them. ”

Wu Xiu glanced at Ni Nan, he also wanted to talk on the podium, but he really couldn't!

The weather is getting colder and colder, and Wu Xiu is more and more fond of going to the library.

It's not that Wu Xiu likes to study anymore, he still holds two books in his hand, and then lies on the sofa in front of the floor-to-ceiling window of the library to bask in the sun.

In fact, the balcony of the dormitory can also bask in the sun, but the dormitory does not have air conditioning, and Bincheng does not have heating like Fengcheng, and air conditioning only exists in the teacher's office area and library.

That's right, Wu Xiu simply went to the library to rub the air conditioner.

Originally, Wu Xiu still wanted to find someone to be his companion, but Zheng Peng had recently started to get closer and closer to Tang Rui, and he didn't have time to go to the library at all. Ni Nan was focused on watching movies and had no interest in the library.

As for Qi Wenhua, a frequent visitor to the library in the 202 dormitory, he now stays in the dormitory to knit scarves for his girlfriend after finishing his homework every day.

This surprised everyone, obviously they didn't expect Qi Wenhua to have this ability.

And Qi Wenhua's explanation is also very clear: "My girlfriend is afraid of the cold, so I specially learned it for her." ”

On this weekend afternoon, Wu Xiu was about to go to the library to sleep, and Qi Wenhua said to Wu Xiu excitedly: "Brother Xiu, accompany me to the business academy! I want to hand over the scarf to her personally." ”

"You're going to find your girlfriend, what am I going to do? Be a light bulb?"

"No, you can be my companion! I'm bored on my own journey. ”

"Don't go!" Wu Xiu refused, "Didn't I go to the library alone?"

"That's different, how close is the library? What's more, it's the first time I went to the business college, and you know that I'm a road idiot, what if I get lost?"

"You can ask for directions!"

"I'm not thin-skinned, I'm embarrassed!"

“——”

"I'm not saying you're thick-skinned......"

"Don't go!"

"A pack of Hibiscus King. ”

"Hehe, what do you think I am......"

"Two packs of Hibiscus King. ”

"No, I ......"

"Three packs of Hibiscus King, plus one more meal. Qi Wenhua said very firmly: "Brother Xiu, you know my financial ability, I can't do it any more." ”

Wu Xiu nodded helplessly and said, "Let's go! Go buy cigarettes first......

Since it was the first time for Wu Xiu and Qi Wenhua to go to the Chamber of Commerce, they inquired all the way and finally arrived at the Chamber of Commerce before dark.

Qi Wenhua surprised his girlfriend, and did not tell his girlfriend that he was coming, but called to ask about his girlfriend's location, and said that he bought a gift for her online, and now the courier brother has sent it.
