"Hey, hey, can you hear me? I'm Wu Xiaoqing, how is this angle, do you still need to adjust? ”

"Hear, this is Yevgeny, about 10 degrees to the right...... Rotate half a turn, it's OK, fix it. The search and rescue team, shouted Yan Xiu, and he ran out again. ”

"It's okay, he found out about the situation, Wu Xiaoqing, if you move faster, the battle in the direction of 10 o'clock has a tendency to expand."

Wu Xiaoqing was so anxious that he was sweating, the drill bit of his impact drill had been changed three times, but the nails couldn't get in.

"This point doesn't work, can you change places? This piece is metallic! This alien's steel plate is too TM hard! Isn't it okay to have a stone on the side? ”

"No...... The rock formations here are very poorly attached and can fall off at the slightest vibration...... So, you change the hot melt adhesive and put the lens on it. ”

Wu Xiaoqing picked up the hot melt glue gun, and while waiting for the heat, he subconsciously turned his head to look at the air behind him.

Just when Wu Xiaoqing was working just now, there were already three people from that direction, if it weren't for Yan Xiu, Wu Xiaoqing would have confessed three lives here. Now that Yan Xiu is not there, Wu Xiaoqing always feels a panic in his heart, and cold sweat constantly breaks out on his back when he is working.

This feeling has never been felt in the previous missions.

In fact, when he first entered this world, although Wu Xiaoqing was reminded many times by the search and rescue team about the danger of the mission, he didn't feel much at that time.

Because the enemies were completely aliens at that time, and when they first came into contact, the flying people were not hostile to themselves, and their flying and flying way of life felt quite poetic - even if they often fought with flying swords. But Wu Xiaoqing has always looked at all this with the mentality of watching a play.

But now it's different.

From entering this world to now, the entire mission has been carried out for more than three months, during which countless video materials, technical meetings and discussions, and even the final nuclear explosion, samadhi, war scenes...... Wu Xiaoqing has gone from perceptual to rational, and every cell in his body has a deep understanding of the true appearance of this world.

Let's take the appearance of three people just now, because the position of the other person is behind him, and the glasses can't be observed at all.

From the time these people appeared in the field of vision to the time they approached him, it was only a dozen seconds. This time is not enough for Wu Xiaoqing to completely screw a screw.

But this little time is enough for someone else to kill him.

Now it is in a state of war, just like the sect closest to Wu Xiaoqing, the sect that is fighting, the rebel army has already rushed into the sect at this time - this means that this sect has basically lost. The defenders of this sect were basically scattered around the sect, trying to rely on their own cultivation advantages to kill a few lone opponents. In this case, Wu Xiaoqing's goal is the most vulnerable.

Wu Xiaoqing tried to concentrate his energy on the melted rubber strip in front of him, and carefully glued and fixed the bracket of the camera.

There was movement behind him again, and it was obvious that there was another fight, someone screamed, and then the sound of flying swords colliding. Wu Xiaoqing could now tell from this voice what happened after the two swords collided...... There was still some distance to hear, but he just couldn't help but look back.

"It's okay, do your thing." The search and rescue team is quite calm, "All the data shows that you are safe, but the unfamiliar environment interferes with your danger judgment system." ”

"They have no power to fight back in front of Xiu, not to mention that you still have a plan that you can call for emergency support at any time......" The voice of the search and rescue team changed, indicating that what he said this time was translated by Yevgny, "It's okay, Qing, you go and rest first, let's debug the data here." ”

Wu Xiaoqing hurriedly climbed on the surface of the island and entered the center of the island.

This island must have belonged to a certain sect before, and you can still see a lot of characters and patterns representing the sect at the entrance. Many words have been faithfully translated—the four precepts of the Tian Yuan Sect......

Common meditation qualifications can also be seen inside the sect, and there are even some "martial arts cheats" engraved with murals on the walls, which reminds Wu Xiaoqing of the classic TV series Tianlong Babu.

It's just that there are no characters on these cheats, and all the drawings are swords—obviously swordsmanship. Because the flying sword does not need to be held, all the sword patterns only have basic angle and speed information.

If it weren't for the reminder of the search and rescue team, Wu Xiaoqing would have thought that what he saw was the force analysis diagram in the physics book, and the cheats were all small swords, and then all kinds of arrows.

According to his previous experience, Wu Xiaoqing needed to wait here for several hours, mainly because the search and rescue team needed to debug the transmission signal of the monitoring screen.

These shots are transmitted by electromagnetic waves, and the transmission method is ladder transmission.

So far, Wu Xiaoqing has installed four points and divided these four points into 1234 in order, so the signal of the fourth point installed now will be transmitted to the third, then to the second, and so on.

In this world where satellites do not exist, this is the only way to rely on this method - otherwise, it is impossible to send such a large amount of image signals directly to the space station with a range of thousands of kilometers.

Wu Xiaoqing took out a tablet from his schoolbag and began to read seriously.

Video Commentary of "High School Physics".

Yan Yan went to a key high school in Shenhai City to record it - it was also her original alma mater.

Compared with the self-study before, Wu Xiaoqing has obviously begun to gradually master some learning methods, plus there is also the teacher's guidance in the video - usually when it is time to get off work, Wu Xiaoqing can directly contact the teacher to ask questions.

Wu Xiaoqing has basically mastered several basic laws of physics, and it is not a big problem to do some entry-level problems. It also made him feel very excited - after a month or two of groping, he finally entered the door. Prior to that, he also participated in the laying of electrical circuits for the space station, and basically laid the foundation for electricity. At least he now knows that the conventional voltage is 220V and the frequency is 50HZ.

For other ordinary high school students, the mastery of these knowledge points may be just a few symbols in the textbook and more scores in the exam.

But for Wu Xiaoqing, it has a completely realistic meaning - just like a few formulas in electricity, Wu Xiaoqing now uses it every day to calculate:

How much electricity does a trapeze need to consume for a day without moving, and how long does it take for this electricity to be fully charged. How long does it take from seeing a flying sword to when it hits you, and how do you react to avoid it......

Yevgeny joked with Wu Xiaoqing a few times, saying that he was now starting to study basic physics, which should be regarded as job training.

It's just that the only regret is that Wu Xiaoqing's qualifications ...... It's just too bad.

In Yan Yan's words, Wu Xiaoqing's junior high school is basically equivalent to not reading.

Studying science is not the same as liberal arts. It's never too late to learn liberal arts, because the knowledge points are all memorized, and there is no obvious correlation between the front and back. Yan Yan remembered that at that time, the science class was transferred to liberal arts, even in the second semester of the third year of high school, and the progress could be kept up after a month or two.

But science...... It's like building a house, the foundation is not laid, and it is built directly on top of it, which will inevitably crumble.

Wu Xiaoqing is now in this crumbling state, and it is difficult to add things to his tower of knowledge little by little.

His earnestness lasted for more than an hour, until Yevgeny finished the simple correction of the problem he had just done and told him: "Forget it, Qing, physics has nothing to do with you, go ahead and turn the screws......

Wu Xiaoqing was a little unwilling: "You just said, how many mistakes are you?" ”

Yevgeny smiled: "5 ways." ”

"Isn't that still the right five ways," Wu Xiaoqing said, "and there has been a lot of progress." ”

"5 are wrong, and the remaining 5 are clear, and some of them ...... You probably haven't read the question yet. Wu, your math foundation is too poor, let's start with junior high school math first. ”

Yan Xiu had already taken Wu Xiaoqing to speed up at this time, their flying swords often had an average speed of more than 300 yards when they were in a hurry, and when Wu Xiaoqing was wearing a windproof helmet, he also said: "Search and rescue team, what did I do wrong, put it on my glasses for me to see." ”

The picture of his question correction soon appeared, the errors were all low-level, Wu Xiaoqing can understand the formula now, but his calculations are full of problems. A simple quadratic equation will not be solved, a simple elimination term will be taken aside, and a two-digit multiplication by a one-digit number will be miscalculated......

Wu Xiaoqing, who looked at it wrongly, was particularly aggrieved - the formulas were all written correctly, and the ideas for solving the problems were also correct, but they were miscalculated.

"Science only looks at the results, not the process," Yevgeny could understand Wu Xiaoqing's feelings, "absolutely correct, this is the greatest charm of science, but also the most cruel place." You have to get used to this cruelty. ”

"Am I too stupid?" Every time he saw his results, Wu Xiaoqing couldn't help but doubt himself like this.

"I've done the IQ test for you more than a dozen times, and you're pretty smart. It's just that the foundation is not enough. ”

"But I'm also 98," Speaking of the IQ test, Wu Xiaoqing was worried again, "The search and rescue team said that we Chinese average 105!" ”

"My test score was lower than yours, 96," Yevgeny said, "but that didn't stop me from being a professor." ”

"The search and rescue team said you were engineering research...... The IQ requirement is not high. ”

"Listening to what you say, then you want to do theoretical research in the future?"

"Of course," Wu Xiaoqing looked at Yan Xiu in front of him, the flying sword under their feet, the wind whirring around their bodies, full of pride, "Either you don't learn, if you want to learn, you must learn the top!" * A great scientist like Instein. ”

Yevgeny's answer was only a hearty smile.

The search and rescue team told the truth: "It's hard. ”

Wu Xiaoqing's courage that he had just mustered suddenly leaked most of it: "Can't I study hard for a few years?" ”

"The harder you try," the team said, "but when this mission is over, it will be easier." ”
