Back in 1978, I was admitted to Northwestern Polytechnical University.

Chapter 171 MIT Library

Seeing the resentment in the other person's eyes, Qin Liang immediately realized: Could this guy be Yang Duo'er's suitor? Yang Duo'er had helped him a lot, including the current hundred-person inspection team, which was also driven by Yang Duo'er, so Qin Liang didn't mind being her protector.

So Qin Liang reached out and put his arm around Yang Duo'er's waist. This bold move made the other students around him widen their eyes, while the foreign guy opposite him completely frowned.

He had been pursuing Yang Duo'er for several years, but she had never even held his hand, let alone put her arm around his waist. She had deliberately kept her distance, which made him wonder if there was something wrong with her orientation. Now, seeing how intimate Yang Duo'er and Qin Liang were, he felt a fire burning in his heart.

"Yang, why? What's so good about this person? What do I lack compared to him?"

"Christian, you're a good person! I'm not good enough for you! I wish you find your true love!"

Qin Liang almost burst out laughing, but he had to hold it in! He kept his arm around Yang Duo'er's waist and walked forward without looking to the side.

Built in 1916, the MIT Library stands out from afar with its towering pillars and round cap at the top, instantly transporting visitors to early American times.

Due to limited space at the institute, this library is far from meeting the needs, so MIT has built five branch libraries in other locations. However... on your first visit, you should definitely come to the main library.

The interior was spacious, and the seating was arranged flexibly. Everyone found the books they wanted to read, picked up a seat, and started reading attentively.

Qin Liang looked through the bookshelves, row by row, and saw that they were all books he had read before, so there was no point in looking at them now. He looked at the second row, and it was still the same books he had read before... After walking around several rows of bookshelves, he heard a cold voice: "What, can't understand it? It's not surprising that an Asian can't understand English, especially these professional materials."

Qin Liang turned his head and, sure enough, it was Christian. He had changed into a suit and was dressed up in a very respectable manner. He had even sprayed some unknown perfume on himself, which smelled pungent.

"Yeah, I really can't understand it." Qin Liang nodded, then looked at the person beside him: "Honey, let's go out!"

Christian had originally wanted to show off his knowledge, after all, he was an elite who had come all the way from private schools! He applied to MIT just to pursue Yang Duo'er, otherwise he would have applied to Harvard and even studied aerospace engineering so that Yang Tian could be his mentor. But he never expected that... Yang Duo'er didn't go to MIT, let alone study aerospace engineering!

Yang Duo'er, after visiting the East a few times, has fallen for this idiot who can't even understand professional English? How could someone from an elite class like you choose an ordinary person?

Christian gritted his teeth: "Yang, someone like that doesn't deserve you! You can't be with him!"

“Christian, who I choose is none of your business. Besides, this is a library, don’t make a scene. You always call yourself an elite, is this what elite manners are?” Yang Duo’er finished speaking and leaned close to Qin Liang: “Let’s go!”

These students will definitely be reluctant to leave once they start looking at the materials. It's not too late to pick them up when the library closes! This is a good time for me and Liangzi to be alone!

Just then, Yang Wei suddenly walked over: "Qin Liang, this 'supercritical airfoil,' you mean supercritical airfoil, right? We didn't learn about this type of airfoil when we studied aerodynamics!"

Everyone else frowned. This Yang Wei, no matter what, only thinks about studying and ignores everything else. Didn't you see that Qin Liang and Yang Duo'er are going out to date? It's a good opportunity to shake off this tagalong.

However... this American doubted Qin Liang's knowledge level. Was Yang Wei just trying to give Qin Liang a chance to demonstrate his abilities?

They were all overthinking it. Yang Wei was so engrossed in his studies that he hadn't paid any attention to his surroundings. Now, he genuinely didn't understand. "Well... the supercritical airfoil was proposed by Whitcomb in 1967. Its characteristics include a blunt, rounded leading edge, a flat upper surface, a concave lower surface near the trailing edge, a thin trailing edge, and a downward curve. This special airfoil is designed to increase the critical Mach number of the airfoil, delaying the phenomenon of a sharp increase in drag at high subsonic speeds, thereby increasing the maximum speed of the aircraft."

"How exactly was it done? I didn't understand those derivation formulas."

"Actually, the formulas in this book do have problems. We can skip these formulas and just follow what we've learned. In our aerodynamics textbook, chapter 9.6.1 discusses the critical Mach number of airfoils, and the formula is..."

Christian's eyes widened.

He had just learned about the theory of airfoils. When Yang Tian was teaching, the homework he assigned them was to write an analysis of supercritical airfoils. He had been studying in the library for three days, but he still didn't understand the formulas in the materials.

Now, Qin Liang is explaining in Chinese, but when it comes to professional terms, much of it is transliterated. It's understandable, and with the formulas Qin Liang wrote down, Christian felt like the clouds had parted to reveal the sun. The derivation was crystal clear!
Qin Liang quickly filled three pages of A4 paper, completing all the derivations. Yang Wei nodded in satisfaction: "Thank you, Qin Liang!"

Do you understand?

Christian instinctively began, "I have a question..."

After he finished speaking, he suddenly realized something was wrong: Why was he asking this Asian for advice? He had clearly come to humiliate him! But... when his gaze fell on the three A4 sheets of paper, seeing the dense formulas on them, he swallowed hard, then pointed: "Here!"

Are you asking me for advice now?

Christian fell silent. Seeing his hesitation, Qin Liang picked up the first sheet, crumpled it into a ball, and was about to throw it into the wastebasket.

"Wait, I'm asking you for advice!"

"Okay, then call me teacher first!"

"teacher!"

"Come here, this lady, call her Master's wife!"

Yang Duo'er smiled radiantly.

Christian gritted his teeth: "Teacher's wife!"

"Hmm, not bad, good student. Now... let my classmate explain it to you. Yang Wei, if there's anything he doesn't understand, you can teach him!"

Christian watched Qin Liang and Yang Duo'er's departing figures with a complicated expression. This guy... he only knows about supercritical airfoils, what's so great about that!
Then look at this young man in front of me. We both listened to it once, but how come he understood it? And he seems to be able to speak fluent professional English too?

"Hurry up and ask, I still need to continue reading after you're done asking!" Yang Wei gave him a dissatisfied look. This guy's comprehension level was too poor, he didn't want to waste too much of his time!
