After a class, everyone felt no different from when they first came down from the multi-axis training machine, the world was spinning, and Steve's speech was fast, like a machine gun, eager to stuff all the research results related to the Saturn 5 launch vehicle into the heads of the students in just one hour.

The fat man looked like he was about to cry after less than ten minutes, and he didn't even have time to pick up the cap of the pen that had fallen on the ground, but this time there was someone worse than his face, a strong man named Anthony, who had been breaking out in a cold sweat on his forehead since he got the textbook, and he wiped it again and again.

The middle-aged man who looked like an intellectual kindly handed over a piece of paper, but the strong man named Anthony didn't take it, staring at the three-stage rocket structure diagram on the page with two eyes, looking distracted, in fact, not only him, but also the high school student no longer had the high-spirited appearance before, and kept scratching his ears and cheeks.

The girl next to Zhang Heng was even more straightforward, directly closed the book, leaned back on the chair, and complained in a low voice.

"Tsk, it's full of professional English vocabulary, and I don't even have a translator at hand, who can read it."

Players who dare to choose a single-player dungeon generally have a certain language foundation, and English, as the world's first lingua franca, is naturally the first language that players will learn to master.

But everyone's mastery is different, and everyone is OK in daily communication, but like now, once it comes to more obscure content, it's time to test everyone's vocabulary reserves.

The high school student's English is undoubtedly much better than his peers, and he is also an astronaut himself, and knows a lot of technical vocabulary spelling, but he still struggles a little in Dr. Steve's class, but compared to the strong man named Anthony, he has completely entered the stage of catching blind.

The middle-aged man who only looks like an intellectual has not changed much, and he still looks like he was slow and logical before, but what surprised Zhang Heng the most was actually the young man who had always been weak, he turned out to be the most serious one among the seven people, and he was still taking notes quickly.

The girl on the side saw that Zhang Heng was paying attention to the young man, and poked her head over, at this time, Dr. Steve was turning his back and writing on the blackboard about the pressure in the chamber of the J2 engine and the rate of oxidant consumption, the girl's chest was pressed on Zhang Heng's shoulder intentionally or unintentionally, and the air exhaled from the nasal cavity made the back of Zhang Heng's neck itch a little, "It's really fake, it won't be just for pretending, maybe there are only some obscene stick figures in his notebook......"

The feeble young man seemed to hear the girl's words, and turned his head to grin at her, revealing a somewhat flirtatious smile.

The latter was taken aback, immediately retracted behind Zhang Heng, and whispered in someone's ear after a while, "I don't like him, he's probably not a good person in the real world, and the uncle over there, I've seen a lot of guys like this in the workplace, and he looks gentle and considerate on the surface, but I know what the hell is going on in his stomach." ”

Zhang Heng's gaze still stopped on the blackboard and didn't say anything.

"But I can see that you are different from them, and although you look the fiercest on the outside, you are actually a good person on the inside......"

"Are you sure?" Zhang Heng finally moved his gaze from the blackboard to the girl's body, and said lightly, "It's a pity that I have killed a lot of people, including underage children, old people who are dying, young soldiers whose wives are still waiting for him to go home, and fishermen who are begging for a living at sea, in fact, I don't remember how many people I have killed, how much blood has been stained on my hands, and I honestly don't care much about the back." ”

The girl's smile became a little forced, "But those are just things that happened in the dungeon, right?" You have to do it, however in real life ......"

"You don't know what kind of person I am in real life, just like I don't know what kind of person you are in real life," Zhang Heng unceremoniously interrupted the other party's words and paused, "But I can probably guess what you want to do, I can only say that you chose the wrong target, if I were you, I wouldn't waste time on me anymore, besides, if you don't mind, please keep quiet, you don't want to listen to the class, there are other people who want to listen to the class." ”

After Zhang Heng finished saying the last word, Dr. Steve also turned around and grabbed his messy hair, "...... Well, that's it for the J2 engine, you can compare it with the F1 engine in the tail, let's take a look at the interstage ring, which contains 8 small rocket engines, which can separate the ring from the second stage rocket, which is an important part of the Saturn V ......"

After more than an hour, Zhang Heng finally got the long-lost purity again, his warning seemed to have worked, the girl no longer pestered him, there was no such physical contact, and there was no whispering in his ear, Zhang Heng could finally pay all his attention to the textbook in his hand.

By the time Dr. Steve finished the lecture, it was 6:22 p.m......., and the old man dragged out the lecture for twenty-two minutes. So let's get here today. After saying the last sentence that everyone was looking forward to, he closed the lesson plan, pushed open the door of the conference room and left in style.

The players in the conference room were also relieved, even the young people who seemed to be serious all the time listening to the lecture were a little unable to hold it anymore, and they were more than two hours of high-intensity study, constantly filling their heads with new knowledge, and everyone would feel tired.

The strong man named Anthony got up from his seat and stretched, but at this time, a short bald man walked straight in from the door, erased the physics of rocket propulsion on the blackboard under the blank gaze of everyone, but left the first chapter in the front, and then picked up the chalk and wrote a few words about the introduction to space flight engineering technology, and smiled.

"Hello everyone, I know you're pressed for time, so let's skip the self-introduction part, and welcome to the engineering class."

"Wait, wait, are you in the wrong place?" There are weak young people, and there are weak ways.

The bald man glanced at his watch, "Oh, there's seven minutes to go, but there's a lot more to go today, and I think we can start a little earlier." ”

"But here's the thing...... We haven't had dinner yet. The middle-aged man who looked like an intellectual smiled bitterly.

As soon as he finished speaking, a food truck was pushed in from outside.

"It's okay, you can listen to me while you eat." The bald man said intimately.
