"The task of rural teachers has been completed and the evaluation is underway...... The evaluation is completed, the completion of this task is A, congratulations to the host, the teaching ability will be greatly improved, and the system will randomly select a technology from this plane as a reward. ”

Pang Xuelin only felt a warm current rushing into his mind.

Suddenly there was a trace of indescribable things in his brain, in the past, when he was in class, although he tried to explain all the knowledge points he wanted to talk about, there were always some incomprehensible places.

But now, Pang Xuelin has a feeling that even if an ordinary undergraduate student is in front of him, he has a way to use a few classes to make the other party thoroughly understand his Ponzi geometry.

Pang Xuelin opened his eyes and saw the system's lottery wheel interface again.

Pang Xuelin didn't bother to look at the reward on the turntable, but asked:

"System, why did I leave so suddenly in the country teacher world this time? I didn't even have time to say goodbye to Xiaohui and A-Qing......"

“……”

"System, is it that some of the issues I just discussed with the Carbon-based Alliance Archon are more sensitive, so you asked me to come back early."

“……”

There was still silence.

"System, is the High Civilization that made you stronger than the Zeroer?"

“……”

"System, are you playing dead?"

"The system doesn't die!"

“MMP！”

Pang Xuelin scolded secretly.

The system is a scoundrel, and he can't help it.

"Okay, system, last question, after I left the country teacher world, the country teacher world time came to a standstill, I would like to ask, is it the time of the entire universe that has come to a standstill, or is it just a small area of time that has come to a standstill?"

Pang Xuelin said.

This time, the system finally replied in a serious way: "After the host leaves the Rural Teacher World, all material time in the solar system of the Rural Teacher World will be reset to zero!" ”

"What do you mean?"

Pang Xuelin was a little puzzled.

The system said: "Time is zero, that is, the entropy of all matter in the solar system is stagnant, and the extrasolar world is not affected in any way, and in the rural teacher world, no civilization can observe the existence of the solar system again." ”

"Well, you're awesome!"

Pang Xuelin couldn't help but breathe a sigh of relief.

No matter what, as long as he continues to grow, sooner or later in the future, he will be able to meet Xiaohui and Aqing again.

After making sure that Wang Muhui and Su Anqing would have no problems, Pang Xuelin focused his attention on the lottery wheel in front of him.

The roulette wheel is divided into six zones, each representing six technologies.

The six technologies are:

1. Singularity bomb

The Singularity Bomb is essentially a mass point, has no size, and an atom is infinity compared to it, it is a miniature model of the large cosmic singularity, and has some parameters of the large cosmic singularity. The Singularity Bomb is surrounded by a miniature black hole with diameters ranging from tens to hundreds of meters, which was not artificially created, but was formed at the beginning of the universe. After being captured by the search fleets of the Carbon-Based Life Alliance and the Silicon-Based Life Alliance, it can be detonated by special means, making it the only weapon in the Village Teacher World that can destroy stars.

2. Stellar frog jumping technique

Using stellar energy to open space-time wormholes for space-time jumps, with a maximum transition distance of 200 light-years, is an essential technology for faster-than-light spaceflight. The only drawback is that after the transition, it is easy to cause the space-time distortion of the galaxy.

3. High-dimensional communication technology

Using high-dimensional space for faster-than-light communication can ensure communication without any delay, even at two ends of the universe.

Fourth, hologram technology

A technology that uses the principle of interference to record and reproduce a realistic three-dimensional image of an object. Ordinary photographic techniques can only record the intensity information (amplitude) of the light, and the depth information (phase) is lost. In the interference process of holographic technology, the superposition of wave peaks and peaks will be higher, and the superposition of peaks and troughs will be flattened, so a series of irregular, light and dark stripes will be generated, so that the phase information will be converted into intensity information and recorded on the photosensitive material.

The first step is to use the principle of interference to record the light wave information of the object, which is the shooting process: the photographed object forms a diffuse object beam under laser irradiation; The other part of the laser is used as a reference beam to shoot on the holographic negative, which is superimposed with the object beam to produce interference, and converts the phase and amplitude of each point on the object light wave into the intensity of spatial variation, so as to record all the information of the object light wave by using the contrast and spacing between the interference fringes. The negative that records the interference fringes becomes a hologram, or hologram, after being developed and fixed.

The second step is to use the principle of diffraction to reproduce the light wave information of the object, which is the imaging process: the hologram is like a complex grating, and under the irradiation of a coherent laser, the diffracted light wave of a linearly recorded sinusoidal hologram can generally give two images, namely the original image (also known as the initial image) and the conjugate image. The reproduced image has a strong sense of three-dimensionality and has a realistic visual effect. Each part of the hologram records the light information of each point on the object, so in principle, each part of it can reproduce the entire image of the original object, and through multiple exposures, multiple different images can be recorded on the same negative, and they can be displayed separately without interfering with each other.

5. Quantum computers

A quantum computer is a kind of physical device that follows the laws of quantum mechanics to perform high-speed mathematical and logical operations, and to store and process quantum information.

It can achieve a transformation for each superimposed component equivalent to a kind of classical computation, all of which are done at the same time, and superimposed by a certain probability amplitude to give the output of a quantum computer. This kind of computation is called quantum parallel computing, and it is also the most important advantage of quantum computers.

6. Antimatter technology

Antimatter is a particle of matter that is similar to the particle of matter, with opposite electrical properties. Each elementary particle has its counterpart. When an elementary particle meets its antiparticle, it is annihilated at the same time, converted into energy.

……

Pang Xuelin's eyes couldn't help but light up.

This trip was not in vain.

Although the scientific and technological level of the earth in the world of "Country Teacher" is low, the scientific and technological level of this world has reached an extremely high level.

Therefore, the technical rewards given are also very entrenched.

However, Pang Xuelin doesn't like the singularity bomb, stellar frog jumping, and high-dimensional communication technologies.

Even if these technologies are drawn, it is like handing over the drawings of a nuclear bomb to primitive people, and there is no meaning.

The real-world Earth simply does not have the possibility of making it possible in a short period of time.

The last three techniques are a bit interesting.

Whether it is holograms, quantum computers or antimatter, they all have certain application value.

Of course, even if the antimatter thing is made, it can only be hidden in the real world as a big killer.

Quantum computers and holograms, on the other hand, are of great use in the real world.

Among them, Pang Xuelin's favorite is quantum computer technology.

After all, whether it is to give MOSS a new home or in the future of scientific computing, quantum computers have unique advantages.

"Host, do you want to start the lottery?"

"Start the lottery!"
