The scumbag students had expressions on their faces like "If you stretch out your head and cut your head with a knife, if you shrink your head it will be a knife too". They regarded death as if they were going home and rushed to the execution ground, not the examination room.

Meng Chao couldn't help but smile when he thought that he had the same expression in his previous life.

The written test lasted for five hours, but only one subject was tested. It was a comprehensive test that mixed biology, physics, chemistry, mathematics, strategic analysis and other courses together, making it extremely difficult.

Moreover, no seats are provided throughout the entire process, and the examination table where the computer is placed is adjusted to an awkward height that is neither standing nor squatting according to the height of the candidates.

Only when the candidate's pile skills reach a certain level can he manage to find a comfortable posture and concentrate on completing the exam.

It is allowed to go out to relieve oneself, but the toilet is at the other end of the examination room, and it wastes a lot of time to go back and forth.

This is another test of teenagers' control over their internal organs.

During the college entrance examination over the years, many candidates have been squatting and standing for several hours. Their blood flow was not smooth, their legs were numb, and they fainted directly.

Even if you grit your teeth and persist, if you cannot concentrate, your grades will not be good.

The candidates walked into the examination room and immediately let out huge wails.

Because the difficulty of this year's college entrance examination has increased again - the examination room is not flat, but the left side is specially raised and tilted 20 degrees from left to right, and the examination table and computer are fixed with screws.

Candidates have to stand on a twenty-degree incline and can hold on for a while, but a comprehensive examination that takes five hours of concentration is too abnormal, right?

Meng Chao couldn't help but chuckle. He remembered that he was also a member of the "wailing crowd" in his previous life.

I really don’t know which unscrupulous examiner would come up with this kind of examination room.

At this moment, he was naturally not afraid of making things difficult for him. According to his student number, he walked to his seat and entered his fingerprint and iris information.

The shutters on both sides slowly rose, enveloping him in an independent space. He could only see the heads emerging from the shutters, but could not see other people's screens, keyboards or their movements.

"Please wear headphones."

A prompt appears on the screen.

Meng Chao put on his earphones, and with a burst of "rustling" sound, there was soon the sound of ghosts crying and wolf howling, like the gates of hell opening, and the sounds of various jackals, tigers and leopards gnawing flesh and blood and grinding bones.

This is a hearing test.

It's not as abnormal as a "psychic test", but it lasts a long time. It's not easy to stay focused for five hours under the harassment of all kinds of strange noises.

Of course, the sound can be adjusted freely, or even turned off.

However, the volume level will also be scored. If you turn it off directly, the score of the listening test will be 0, and you will be judged as "not strong-willed enough to apply for a major that requires mental stability."

Meng Chao casually adjusted the volume to the highest level, and along with the howling of ghosts and wolves, he shook his head and whistled.

Boom, boom, boom.

Someone knocked on the partition.

When he looked up, he saw the invigilator, staring at him with incredulous eyes.

"ah?"

Meng Chao turned on his headphones and was confused.

A deafening monster roar came from the headphones.

After hearing this, the invigilator's eyes became weirder and he said softly: "Don't make any noise to disturb other candidates."

"Oh, I'm sorry."

Meng Chao shut up, re-entered the state, and watched the countdown appear on the screen.

Half a minute later, the first question popped up on the screen, showing an armored rhinoceros.

Candidates need to draw a diagram of the main organ structure of the armored rhinoceros and point out its weaknesses.

This was so rare that Meng Chao was attracted by it. He immediately started writing on the drawing board like flying skills.

The second question is about the five major types of crystal engines. Draw their basic structure diagrams and fill in the psychic energy conversion formulas.

The third question, "Nine Great Stake" contains eighteen kinds of breathing methods and meditation methods, and their main points are listed respectively.

…

Question 16 is a comprehensive application question.

"Suppose a 9989 kilogram sword and halberd demon pig king rushes towards you at a speed of 180 kilometers per hour, and you are a person wearing a "Sword and Shield-2" reinforced exoskeleton, turning on the "heavy defense"

"Model" ordinary soldier, who is 1.75 meters tall, weighs 82 kilograms, and has well-proportioned muscles, how far are you likely to be knocked away by the sword, halberd, and demon pig? Will the reinforced exoskeleton be damaged, and will you be injured?

"If the reinforced exoskeleton is damaged, how might it need to be repaired.

"If you were injured, how would you need treatment?"

This kind of comprehensive question has a lot of room for free expression, as long as it is meaningful.

Meng Chao wrote with great energy, and the clicking sound of the keyboard never stopped.

In a nearby cubicle, there were several candidates who couldn't stand the monster roar coming from their headphones and turned off the listening test.

But the crackling sound of the top student Fenjuan Canyun tapping the keyboard made these poor students scratching their heads and scratching their heads even more and couldn't type even a word.

Thinking about it, it's better to put on the headphones again. It's better to endure the torture of the monster than to be ravaged by the academic master.

Meng Chao passed all the tests and reached the final essay question in just over two hours.

"Briefly describe the development ideas and styles of thermal weapons after Dragon City time travel."

This is a big question.

He pondered for a moment and began to write.

"Half a century ago, when our ancestors traveled to another world, they were stunned by various incredible physical and chemical phenomena.

"A metal that was originally as hard as iron will undergo drastic changes in hardness and toughness after being left overnight.

“All kinds of alloys called ‘stainless steel’ develop rust spots at a speed visible to the naked eye.

"Lead ingots and copper blocks with single properties, obviously stored in the warehouse, will turn into various new materials with strange properties that are unheard of on the earth.

"Although the changes in most materials are very subtle and do not cause much hindrance to daily life, even if the failure rate of complex machinery such as civilian computers has increased significantly, it is not unusable.

"But the high-precision weapons industry pays the most attention to material stability. Even if a key material is shortened by a hair, or the hardness and toughness change by 1%, it will lead to catastrophic consequences.

"As long as one part of the jet engine of a supersonic fighter jet is changed, it may explode in the air.

"If a component in the gyroscope of a surface-to-air missile expands or shrinks slightly by 0.01 mm, the missile will lose or even change its attack target.

"Welded with special solder, the seemingly indestructible war fortress may collapse in an instant as the properties of the solder change, burying all the soldiers inside.

“At first, scientists were puzzled by this phenomenon, calling out ‘magic’ and ‘witchcraft’, and suspected that we had traveled to the legendary magical world or the world of immortality.

"But even magic and supernatural powers can't stop the people on earth from persevering in pursuing the truth. Soon, we discovered the super energy source of 'psionic energy'.

"Psychic energy is a very active energy that can invade the molecular level of matter and directly interfere with atomic nuclei.

"The latest scientific research shows that the protons or neutrons in the nucleus may form a spherical vibration energy layer by two balancing forces, internal and external.

"On the earth, there is no radiation that can interfere with the vibration of the energy layer of the atomic nucleus. Therefore, atoms are considered indivisible, and the material edifice formed by the accumulation of countless atoms is also indestructible. At most, it can only be changed at the molecular level.

"But in another world, psychic energy bombards atomic nuclei, which can easily change the spherical vibration energy layer of protons or neutrons, changing the properties of elements at the atomic level.

"We have roughly figured out the reasons for material variation, but it does not help solve the imminent crisis.

"Yes, scientists can use crystallization materials unique to other worlds - various crystal stones, crystal nuclei, crystal marrow and crystal liquids to create relatively stable cutting-edge materials.

"We can also vigorously develop biochemical technology, use monsters to fight monsters, and even completely transform our civilization into a biochemical civilization that is completely different from the earth.

"With the continuous exploration of psychic technology, one day we will master the technology of bombarding atomic nuclei with psychic energy and controllably changing protons or neutrons. By then, we will be like the legendary wizards or monks who have mastered the technology.

The ability to 'turn stones into gold' and 'throw beans into soldiers'.

“But these are things for later and require the investment of a lot of precious resources and even more valuable time.

"Right now, our understanding of psychic energy is still very shallow, and crystallized materials are very rare and expensive, making them unsuitable for refining into disposable weapons and ammunition.

"In the face of the menacing beast tide, in addition to using crystallized materials to make cold weapons that can be consumed many times to let martial arts shine again, we urgently need low cost, large quantities, easy operation, and are not affected by psychic energy as much as possible

Thermal weapons!

"And just like that, a genius idea was born.

"If we are temporarily unable to create very stable, accurate and expensive high-precision weapons in the treacherous and unpredictable environment of another world, can we do the opposite and greatly improve the weapon's fault tolerance and pressure resistance, manufacturing

How about producing a large number of "silly, big, thick and black" weapons?

"Since the most precise core structure of thermal weapons cannot be prevented from undergoing subtle changes in volume, density, hardness and toughness, then the core structure can be simplified and created. Even if a 1% deformation occurs in key parts, the battle will not be affected, even if the gun is fired.

Is it possible to use a weapon that can keep firing its second shot until it reaches the 100th shot even if parts are being dropped while it is crackling?

"In fact, not only does it exist, our ancestors are also quite good at this style.

"Two hundred years ago, on earth, our ancestors and their teachers used this idea of ​​'silly, big, thick, black, durable, high quality and low price' to create the torrent of steel.

"At that time, any tractor factory could be transformed into a tank factory, and such a factory was subjected to indiscriminate bombing by the enemy day and night. Fierce fighting even broke out right in front of the factory. The production workers were all novices who had just been trained for a few weeks.

Obstructing seemingly clumsy tanks one after another, they rumbled off the production line and went directly to the front line, beating the enemy's most elite weapons into scrap metal.

"The environment in other worlds is even worse than the several all-out wars in the Earth era.

"Then temporarily put aside the research and development of high-precision weapons, lower the technical standards to the level two hundred years ago, use multiple turrets to increase firepower, use densely packed rivets to avoid the mutation of welding materials, and use rigid suspensions with continuously thickened axles to avoid

Failure rates of various complex suspension structures.

"Although the weight is definitely higher than the same type of weapons in the Earth era, the powerful output power of the spar engine makes it possible for such a steel behemoth to run rampant on the battlefield.

"With the continuous development of technology, the advent of various biochemical brains and super brains, as well as copying the brainwave data of heroic spirits, creating artificial intelligence with extremely high degree of freedom, and engraved runes, which can absorb spiritual energy and form a spiritual magnetic field.

new armor.

"The steel behemoth equipped with these equipment may look old, rough, and clumsy, but in fact, it is a thinking tank or armored airship. Its combat effectiveness far exceeds the strongest weapons of the same type in the earth's era.
