Chapter 45: Detection Eye
……

Electromagnetic waves are actually a form of light.

Infrared light is the part of the electromagnetic spectrum between visible light and microwaves, and its wavelength is longer than that of visible light.

Light is one of the most essential things in this world.

Color is merely the visual perception produced by the human eye after distinguishing different light waves.

Light not only illuminates the world, but also represents the flow of energy.

Anything, as long as its temperature is higher than absolute zero, will emit a certain intensity of infrared radiation energy.

Since electromagnetic waves themselves are a way of energy propagation, infrared rays also carry the task of energy transmission.

There is a close connection between the intensity of this radiation energy and the temperature of the object, which is specifically a proportional relationship.

The higher the temperature of an object, the greater the infrared radiation power it emits and the stronger the energy it contains.

This means that the temperature of an object can roughly predict the intensity of energy it can release.

The essence of Wu Wen's infrared vision ability is the ability to directly observe the infrared radiation emitted by objects.

With this ability, he can intuitively see the distribution and changes of surface temperature of objects, as well as the differences in temperature between different objects.

By combining the relationship between an object's temperature and infrared radiation power, he can gain insight into the energy strength contained in an object at that moment.

Therefore, Wu Wen felt that he could develop this infrared vision ability into: the eye of detection!
In the tent.

Wu Wen placed two glasses of water on the table.

One cup of cold water and one cup of hot water.

To ordinary people observing with the naked eye, there seems to be no difference between the two glasses of water.

But in Wu Wen's eyes, the scene he saw was quite different.

The cup of hot water appears redder under infrared vision because its temperature is higher and the infrared radiation it emits is stronger.

When Wu Wen mixed the two cups of water at different temperatures together, he saw a scene like rolling clouds and mist.

This scene is invisible to ordinary people. It is a thermal image formed by temperature differences.

"As I recall, the infrared radiation power emitted by an object is proportional to its temperature, but what is the specific proportionality coefficient?"

Wu Wen thought in his heart.

This was the first time he felt that he had not studied well before. The answer was right in front of him, but now he didn't know it. It was such a pity.

If you want to know the answer now, you need to summarize and deduce it slowly by yourself.

"Let me think about it carefully. What specific data information is needed to deduce this proportionality coefficient?"

"Infrared radiation power, and the corresponding temperature data..."

Wu Wen lit a small stove in the tent.

There was a kettle of water on the fire.

When the water boils.

The water temperature at this time is about 100℃.

Next, Wu Wen used infrared vision capabilities to observe the thermal image of the hot water.

Although he did not have a professional infrared radiation meter to directly measure the infrared radiation power, he could estimate it indirectly by observing the temperature distribution in the thermal image.

Carefully analyze the thermal images and compare the temperature differences in different areas to preliminarily determine the intensity of infrared radiation emitted by the object.

Wu Wen then began to record the infrared radiation of objects at different temperatures one by one, and carefully measured and recorded the temperature data of each sample.

Collect enough data.

Wu Wen conducted an in-depth analysis of these data.

By plotting the relationship between infrared radiation power and absolute temperature, the relationship between the two can be intuitively observed.

In this way, the proportionality coefficient between the infrared radiation power emitted by an object and its absolute temperature can be derived.

The data collected needs to be sufficient, because only in this way can Wu Wen get accurate conclusions.

So, for three or four days, Wu Wen stayed in the tent, boiling water repeatedly, even though this behavior seemed very strange to others.

He didn't drink the water, he just kept heating it, waiting for it to cool down, and then heating it again...

And so on and on.

Master Zhu Jiu had come to ask many times, wanting to know what he was doing?
To Master Zhu Jiu, Wu Wen's answer sounded like he was just joking.

Boiling water is also a kind of fun. "Awen, if you are really bored, you can go out of the tent and take a look outside."

Until the fifth day.

Wu Wen finally finished the "water boiling task" in the tent.

"Okay, the data has been collected almost completely, and it's time to collect other types of data next." He thought to himself.

He walked out of the tent and looked up at the sky.

The sun is unusually bright today, and it feels warm on my body.

However, there were large and thick clouds floating in the blue sky, which caught Wu Wen's attention.

Look up and gaze at the clouds, using your infrared vision ability to penetrate the clouds and observe the temperature distribution inside the clouds.

In this way, he was able to accurately determine the thickness and structure of clouds and, therefore, predict weather conditions.

High-level clouds are usually associated with stable atmospheric conditions and they are like a thin veil covering the sky.

Low-level thick clouds are like heavy quilts, heralding the arrival of precipitation or thunderstorms.

Based on his experience and observation, Wu Wen gradually identified various cloud types such as cumulus clouds, stratus clouds, and cirrus clouds, and determined their corresponding weather conditions based on their shape, texture and temperature characteristics.

"Is this... the calm before the snowstorm?" Wu Wen suddenly had a premonition in his heart.

In order to verify his judgment, he turned his head and looked at the towering arrow tower on the wall of the Dazhai.

Climb up the arrow tower.

"Captain Wu Wen, what's the matter?"

The soldier guarding the arrow tower today saw Wu Wen coming and asked respectfully.

"It's okay, I just came up to take a look."

Wu Wen came to the edge of the arrow tower and looked up into the distance.

It was found that there is a huge temperature difference between the surface and the cloud tops.

This difference is one of the important bases for weather forecasting.

Wu Wen analyzed the temperature distribution map and found that unstable energy was accumulating in the atmosphere.

From this, he inferred that severe convective weather might occur.

Observed for a long time.

The cold wind made my body cold.

It is confirmed that the weather will soon undergo a major change.

Only then did Wu Wen prepare to leave the arrow tower.

"Goodbye, Captain!" the guard said respectfully.

Wu Wen looked back at him and said, "The weather may change. Please remind everyone to keep warm."

Then, he left amid the soldiers' surprised gazes.

"This 'detection' ability is really useful. It is much more accurate than simply observing weather phenomena to predict the weather."

As Wu Wen walked on the road, he couldn't help but ponder in his heart.

"Is this a kind of...special 'qi-reading technique'?" He smiled, thinking that the idea was quite novel.

at this time.

The sound of hurried horse hooves suddenly broke the silence around.

In this big camp, who dares to ride a horse so recklessly?

Wu Wen was surprised and looked in the direction of the sound.

I saw a group of cavalrymen galloping towards the gate of the stronghold at lightning speed, led by a heroic young general.

This young general was the one who came to rescue Wu Wen on the night he was attacked.

Later, Wu Wen made special inquiries and found out that this person was the famous super-powerful general Luo Shixin.

Born with supernatural powers and the ability to see at night, he started fighting on the battlefield at the age of thirteen. Now, he is only in his early twenties, but he has already conquered the world.

"What are you going to do in such a hurry?"
