"Mom, today I met the alien 'Betansi Man' in the underground square"

"Oh." There was nothing strange about the whole family, even his sister didn't feel the slightest surprise, which made Qin Wushuang feel that he was thinking of an alien instead.

Then I thought about it, I'm afraid that only if I don't go out of this gate, I don't go out of the second door, the school and the family are two points and one line, and Qin Wushuang, who is dedicated to the game, will not even know this bit of common sense!

The old ways, sports, reading books in the library, reviewing classes, and a peaceful day has passed. The hard and boring but full and warm days were repeated like this, and soon it was Friday, March 18th.

"After class in the afternoon, let's go to the Battle.net battle game together? It's been a few days since we've played together. Xu Xiaopang whispered to Qin Wushuang in class.

Qin Wushuang looked at Xu Xiaopang's evil eyes, and probably wanted to torture and kill himself again, but he didn't see him for three days, although he didn't have much time to play these days, but he used the various functions of the A-4 heavy mecha decently, and it was estimated that who would abuse whom was not certain

Casually replied, "Okay."

"This time, I changed to the ...... of the faster SR series"

"Student, please stand up and answer the Doppler effect formula for sound"

Qin Wushuang thought that Xu Xiaopang had been caught by the teacher, and threw a sympathetic look.

"It's you, you don't have to look anywhere else" Looking at the dead eyes handed over by the squad leader in front of you, Qin Wushuang understood,

"The formula for calculating the Doppler effect of sound is: ν(a)=((u+v1)/(u-v2))ν(b)."

"Very good" but the teacher obviously doesn't want to let go of the majesty of the "Living Hades" who dares to challenge the whole school is famous.

"I think this student has obviously done enough homework before class, and everyone should learn more from this classmate." Looking at the rolling eyes of Xu Xiaofang's classmate in front of him, Qin Wushuang had never felt praised in this world.

"Could it be that the Living Yama has changed his personality today," the whole class looked at the Living Yama in surprise, they really didn't expect that the Living Yama would have a day of boasting.

Next, please ask this student to write the calculation method of the Doppler effect of light on the blackboard in front of you and explain it: "Looking at the face full of frost, the living Hades are the living Hades, and there is not even a step down now."

At this time, the sympathetic eyes of the whole class were focused on Qin Wushuang, and they could all feel the coming of death.

However, things did not happen as everyone expected, Qin Wushuang strode forward, and wrote down 3 calculation formulas with a beautiful chalk brush,

"The Doppler effect of light can be experimented

......" With Qin Wushuang's explanation, all the students below were as if they had seen a ghost,

"When did the gangsters of Shuguang Middle School become a good student, could it be that King Xuanyuan possessed him?"

Xu Xiaofang's small mouth opened into an O-shape below, although the library had encountered it many times, but Xu Xiaofang always thought that Qin Wushuang was deliberately attracting her attention, this kind of boy Xu Xiaofang has seen I don't know how much, after all, he studies well, he is beautiful, his family background is also good, and there are really many people who pursue him.

"From the above three formulas, we can finally derive ν(a)=sqr((1-β)/(1+β))ν(b)." Earth-shattering applause rang out.

"I hope this student can continue to maintain, and the next thing we want to explain is ......"

"Dude, you won't be possessed by Yuan Daoguang, you actually defeated the living Hades." Xu Xiaopang said like a monster.

(Yuan Daoguang is the greatest physicist and mathematician in the galactic calendar, known as the Einstein of China, Yuan Daoguang verified the mathematical model of the super-dazzling theory in the year 362 of the galactic calendar, 'the super-dazzling theory produces particles such as photons, quarks, and electrons through the different ways of particle vibration'.) Yuan Daoguang produced tachytons with zero mass beyond the speed of light through anti-vibration quark super-dazzling experiments, realizing the unification of quantum mechanics and electromagnetism. According to Einstein's theory of relativity, as long as the speed of any object is about close to the speed of light, the mass is doubled until it reaches infinity, so no object can accelerate beyond the speed of light, but the superdale theory bypasses Einstein's theory of relativity that no object can accelerate beyond the speed of light by directly generating tachyons that exceed the speed of light. ）

Of course, it is not only the tachyon that can exceed the speed of light, like the graviton, which can also exceed the speed of light to some extent, and the graviton and light travel at a speed of 300,000 kilometers per second, but the graviton propagation is not in a vacuum, but through a higher dimensional space.

Therefore, in places where neutron stars, white dwarfs, black holes and other mass are very large and space is seriously distorted, gravitons propagate at the speed of light in higher dimensional space, but the detection data of human devices in 3D space show that the graviton propagation speed in space exceeds the speed of light.

This theory was proved by observing that the speed of gravitational waves generated by the collision of two neutron stars was greater than the propagation speed of various rays and electromagnetic waves generated by their collision in 2387 AD.

To get back to the point, Qin Wushuang's review during this time was not a joke, but Qin Wushuang didn't dare to talk to Xu Xiaopang anymore, after all, it was not a joke to provoke the living Hades again.

"There is one less black and white sheath in our class today, I didn't believe that sows could go up trees before, but now I really believe it." Xu Xiaofang turned around and glared at Qin Wushuang after class.

"Shibei should be impressed in three days, not to mention that it has been a week, we must look at things with a changing eye, rather than staying in the past, it is not a good habit to stick to the old ways." Qin Wushuang said angrily,

Xu Xiaofang did not refute as usual, it seems that Qin Wushuang's performance this time really gave him a great shock, he just looked at Qin Wushuang's eyes with surprised eyes, wanting to see a little end and tail from it, of course Qin Wushuang will not show weakness, he is a human being in two lives, and he is twice as old as you, are you still afraid of you being a little girl.

"In broad daylight, you need to pay attention to the impact, don't you see that there is a single person next to you, how can you discharge us like this, how can we live" Xu Xiaopang said and used his hand between the two

"Hmph" Xu Xiaofang turned his head,

……

On the way to the network center near the school,

Xu Xiaopang said to Qin Wushuang, "You don't really have a leg with Xu Xiaofang, right?" Otherwise, she can't get along with you all the time. ”

"How do I know, who knows what's crazy about her."

"I think she must be happy with you, but our squad leader has a first-class figure and first-class appearance, so seize the opportunity."

"Come on, you, you are with me every day, and you don't know the situation, if she is interesting to me, it is the sow who goes up the tree."
