It's definitely a cheat.

After Jiang Jiuling changed several metal patches in a row, he determined it again in his heart.

This kind of technology of direct perspective on metal will not appear even in another thirty years, and the only thing that can achieve a similar function in memory is the radiographic flaw detector.

But that kind of thing relies on radioactive rays to penetrate metal, and looking at metal with it is even more blurry than going to orthopedic films.

When testing, even the inspector can't even run eight feet away, who dares to get close to it and radiate it?

That......

Does this thing have radiation?

Jiang Jiuling suddenly thought of the knowledge points he had seen in the book before, the radioactive metals in this world were too powerful, and there was no record of human beings successfully hunting them.

"Teacher He, what is the technical principle of these insight glasses?"

"Technical principles?" Mr. He asked curiously, "This is a gift from the Sacred Industrial Code from the Title Engineer, you ask about the technical principles?"

"I don't know about that, I'm afraid you'll have to ask the Codex. ”

Mr. He doesn't know the technical principle, but he knows the limitations of use.

It turns out that this insight glasses cannot see through all objects without limits.

It can only see through six common metal materials, and the perspective range is no more than one meter, and the strength of the perspective metal is only 0.5 mm.

After "......" knew these data, Jiang Jiuling was a little reluctant to speak with his insight glasses.

The plot in the novel is shattered.

However, if you think about it carefully, although the function of this insight glasses is a bit frivolous, so that the Industrial Committee gave it to No. 1 Middle School as teaching equipment, and No. 1 Middle School simply locked it in the cabinet.

But this just shows that the value of insight glasses is not too precious.

There must be a lot of more powerful and extraordinary items out there, and maybe some of them are more powerful than cheats.

After viewing the treasure of the town school of No. 1 Middle School, Teacher He asked Jiang Jiuling with satisfaction what he needed to improve the excavator model, and it was best to make a list of materials.

There is a lot of messy materials for students to do experiments in the science and technology building, and because of the large number of students, there is always some leftover every time they buy materials.

These things are not like paper, pen and ink that can also be used in ordinary life, so even Mr. He doesn't know how many bits and pieces are piled up in the warehouse of the science and technology building.

After chatting for a while about the materials needed, Teacher He simply asked Jiang Jiuling to come to him to get the warehouse key when he needed it, and go to find it himself.

......

In the afternoon, classes are still to review and explain the difficult points on the past high school examination papers.

The total score of the college entrance examination is 710 points, including 120 in Chinese, 120 in mathematics, 100 in foreign language, politics and science, and 70 in biology.

Last year, the admission score of Hudan University was 562 points.

By the time of the last class, Jiang Jiuling had already flipped through all the class books.

This is not the earth, although it may be due to parallel worlds, it has many similarities with the earth, and even many historical ancients, including celebrities in modern society, are highly similar.

But it's still a new world, and it's full of all kinds of magical worlds.

Among them, the two courses that have changed the most are language and politics.

Politics covers major historical events of recent times and their impact on humanity. For example, the war launched by the United States in the Gulf last year was mainly divided into two military operations, one was the Desert Shield and the other was the Desert Storm.

The purpose of these two US military operations on the planet is to maintain their oil hegemony. But in the books here, oil is only one of them.

Oil is a non-metallic resource, and it can still be collected through drilling wells.

But those metal resources, especially scarce ones, have become extremely difficult to obtain. During Operation Desert Storm, the United States did not hesitate to deploy heavy armored forces on the ground and send elite rangers to encircle and suppress a metal gathering cave that was classified as a forbidden area by the local country.

It is home to a group of ordinal 24 metal variants that can only be found in the desert, the chromium-eating creepers.

In the Metal Species Atlas, the ordinal number 24 metal is the steel-chromium salamander, a metal species that only occurs in deserts or arid regions.

Its variant, the chromium-eating creepers, is a group of terrifying metals that only live in the desert regions of the Middle East and are called demons by the locals.

The Chromium Creeper feeds exclusively on the Steel-Chrome Salamander, which, unlike the Steel-Chrome Salamander, has the ability to breathe fire.

It does not breathe fire, but it can release highly toxic substances and has defenses far superior to those of the Steel Chrome Salamander.

It is as dangerous as demons.

After hunting it, it is only natural that you will receive a reward equal to the risk.

In addition to the abundant chromium metal that can be collected from its body, its blood will be coagulated and turned into a very valuable ultra-high-purity chromium metal.

This ultra-high purity chromium metal can be used to make metal sputtering targets, which is an important raw material for the production of modern electronic information technology.

Jiang Jiuling's mood was agitated when he saw this history, it turned out that here, ultra-high purity metals could save countless complicated refining steps and be obtained directly from the blood of metal species.

But this also creates a big problem.

In the language and politics papers of the college entrance examination, once there are questions similar to Operation Desert Storm, he can easily lose points.

These two subjects originally had to rely on rote memorization, and Jiang Jiuling may have remembered a lot of knowledge points in the past, but now he has forgotten them all.

There is less than a month to go, so how much can I memorize.

With 120 points in mathematics and 100 points in foreign languages, Jiang Jiuling is sure to get at least 200 points.

70 points in biology, it's no problem to get 60 points in review.

Because the biological content at this time is very simple for Jiang Jiuling, it is all the content of cells and common elements.

With the progress of science, Jiang Jiuling's biology at the time of the college entrance examination has appeared a large number of test points on DNA, genes, and neurons, and a batch of difficult ones.

100 in chemistry, 50 to 60 points is no problem.

I don't dare to estimate the score too high, because I am afraid that in case of chemistry and how can ferric oxide be obtained from ferric oxide pigs?

Or the highly (toxic) chemical potassium dichromate, which is stored in the steel chromium salamander.

The chemistry books have been turned over by him, and the knowledge related to metals accounts for about one-third, and he will inevitably be tested in the college entrance examination.

100 points in physics, 95 points is no problem.

Physics is a test of formulas and laws, and this grasp is very large. In the book, Jiang Jiuling did not turn to the topics related to metals, but all the principles of electricity, the refraction of light, energy, gas, heat and so on.

Even if he brought this knowledge from a university textbook, Jiang Jiuling could explain it to the truth.

The total score is 710, and now there are 420 points, which is nine out of ten.

If you want to achieve excellent results in the college entrance examination, you can rely on the admission score of Hudan University, which has a score of about 560 points.

Jiang Jiuling has to score at least 145 points in the 240-point paper on language and politics.

Under the premise of special admission conditions, Jiang Jiuling wanted to experience the college entrance examination again with his true ability, and set the score line at more than 560 points.

It's about how many resources he can get from the school when he goes to college.

A student who is admitted by special recruitment is obviously not as important as a student who has special recruitment conditions but is still admitted with high scores based on ability.

Jiang Jiuling is a top student, and he is confident that he will be able to improve his language and political knowledge a lot within a month.

At the same time, he can also learn more about the world in the process of learning.
