The catacombs were colder than the ground.

The highest temperature of the cave where the Demon Suppression Tower is located does not exceed ten degrees.

The further down, the lower the temperature.

When the tomb door is opened.

Bursts of cold air poured out like a tidal wave.

A cold wave was even formed that was visible to the naked eye!

A white mist filled the field of vision.

Although the biochemical suit has the function of antivirus, it has no obvious resistance to low temperatures.

The four members of the archaeological team who pushed open the tomb door bore the brunt of the attack, overwhelmed by the terrible cold wave.

The originally cold tomb door even condensed a layer of frost at this moment.

A chill to the bones seemed to freeze them over the gloves.

The four were horrified.

They didn't bother to push the tomb door open completely, and instantly retreated from the tomb door.

But just after these few breaths, several people only felt as if they had fallen into an ice cave, and they shivered.

"There's something wrong with this, too, it's too cold."

"Command, it's too cold inside the Demon Suppression Tower."

Mu Yang stood less than three meters in front of the tomb gate, also shrouded in the cold wind.

He also felt this unusual chill and couldn't help but look at the thermometer hanging on the wall.

"Three degrees below zero!"

When he saw the temperature on the thermometer clearly, Muyang's pupils suddenly constricted, and he was frightened.

-3 degrees Celsius!

He clearly remembered that before the tomb door was opened, because of the closure of the anti-biochemical room, coupled with the activities of these people, the temperature far exceeded that of the outside world, and it had reached about fifteen degrees.

But the moment the tomb door opened, the temperature in the room dropped to below zero.

This means that the temperature in the Demon Suppression Tower is far lower than this problem!

-5 degrees Celsius?

Or minus 10 degrees?

Or minus 20 degrees!

Muyang didn't know, and he couldn't figure it out.

Because it's not scientific at all.

The Demon Suppression Tower is located in the Great Northwest.

It's May again, and summer is about to begin.

These days, the outside temperature is getting higher and higher day by day.

It's normal for the temperature underground to be cooler than above ground.

The temperature of the cave is understandably lower than that of a normal basement.

But to say that the temperature is below zero, it is absolutely impossible.

At least scientifically, this is absolutely impossible.

But.

This impossible thing is really happening now.

The temperature in the Demon Suppression Tower is beyond the scope of what science can explain, and it is also beyond the scope of normal people's understanding.

Just when Mu Yang's heart was shaking, the temperature of the biochemical room was still dropping at a rate visible to the naked eye.

-5 degrees Celsius.

Octave minus zero.

-10 degrees Celsius.

-15 degrees Celsius!

-20 degrees Celsius!

Eventually, the temperature in the room stopped at minus 33 degrees!

Such a cold temperature was unbearable for archaeologists in less than a minute.

They had to urgently exit the room.

On the Internet, it exploded.

"Damn, that was the situation just now, is there a big guy who can explain it."

"This has to start from a long, long time ago."

"A long, long time ago, the Cybertrons came to Earth. One of the robots' refrigeration equipment accidentally crashed into the Demon Suppression Tower, and that's what happened now. ”

"Got it?"

"Funny, but the temperature of the Demon Suppression Tower is too low. I just saw the thermometer on the wall, tsk, more than thirty degrees below zero. ”

"Meng Xin just came, and I wanted to ask a question, is this normal for him?"

"Nonsense, it's definitely not normal."

"Let me briefly analyze that under normal circumstances, the temperature underground is lower than that above ground, but the temperature difference will not be so serious."

"For example, in the great northwest, when the ground temperature is more than 30, the basement can reach about 20 degrees, which is already a very ideal temperature."

"Another point is that the temperature of the ground is relatively constant, and it is less affected by the climate, so there will be no colder ground and colder underground."

"That's why it's said to be warm in winter and cool in summer."

"What is the situation of more than minus 30 degrees, many people may not have a specific concept."

"I'll give you the analogy of throwing a glass of boiling water into the sky, and when it falls, it's ice slag."

"Is there a big guy who can explain that it is normal for such a temperature to occur in the Demon Suppression Tower?"

"You're kidding us, it's definitely not normal."

"Rub, it can't really be Xuantong's resurrection."

"I've heard that zombies are extremely yin creatures and like to live in cold places. And when zombies appear, the temperature will also be lower. ”

"Let's not talk about whether zombies exist or not, even if zombies do appear, it is impossible to cause a low temperature of more than minus 30 degrees."

"With the production capacity and technology of ancient times, it is impossible to artificially create a low temperature of more than 30 degrees."

"I don't agree with what you say."

"Can science manage our immortal cultivation?"

"We don't accept magic either."

"Don't pretend, it's a showdown, in fact, I'm a cultivator of the Hidden World Sect. Now that the Demon Suppression Tower is born, I won't pretend anymore. Immortal cultivation cheats are given away, as long as 998, you can get a set of immortal cultivation techniques. ”

"There is no guarantee of success, after all, not everyone is qualified to cultivate immortals."

“.........”

"Big guy, ask for a cheat."

“.........”

While the melon-eating crowd was having a heated discussion, the archaeological team also fell into a heated discussion.

They expected that the Demon Suppression Tower might be extraordinary.

But no one expected that the problem would be so big.

As soon as the tomb door was opened, an unexplained situation appeared.

The low temperature of minus 30 degrees Celsius, what kind of concept is this?

In order to accurately express the degree of coldness, the meteorological profession has developed a "cold degree scale", and the temperature is divided into eight levels from low to high from -40 °C to 9.9 °C:

The first level is "extremely cold", below -40°C;

Level 2 is "Very Cold", -30°C to -39.9°C;

Level 3 is "Severe Cold", -20°C to -29.9°C;

Level 4 is "Great Cold", -10°C to -19.9°C;

Grade 5 is "Xiaohan", -5°C to -9.9°C;

Level 6 is "light cold", 0°C to -4.9°C;

Grade 7 is "slightly cold", 0°C to 4.9°C;

Level 8 is "cool", 5°C to 9.9°C

More than minus 30 degrees Celsius, which is already a very cold weather.

People working in this kind of weather can be life-threatening if they are not careful.

The point is, the temperature in the Demon Suppression Tower is abnormal.

In previous years, only the coldest time could occur in Tohoku and other places.

What is the Demon Suppression Tower?

Great Northwest.

What time of year is it?

May.

In the great northwest in May, the temperature in the Demon Suppression Tower will not drop below minus 30 degrees, and this situation is unexplainable.

It doesn't make sense.

For a time, the archaeological team fell into a quarrel.

At this moment, even people who don't believe in ghosts and gods can't help but be a little more afraid of the Demon Suppression Tower.

This place is too evil.

But the evil door is the evil door, and how to deal with this matter now is the most important thing.

The archaeological team reported to their superiors when the discussion was fruitless.

In the end, I got a reply from my superiors.

I don't believe in ghosts and gods.

Don't believe in demons.

Keep exploring.

Be sure to dig up the real secrets of the Demon Suppression Tower!

With the instructions of the leader, the archaeological team no longer had any opinions.

The higher-level departments even sent a large amount of cold-proof materials through military transport planes, as well as equipment that can be used in extremely cold conditions.

At this time, it was only half an hour before the Demon Suppression Tower opened!

In the end, the five people, led by Mu Yang, became the first batch of members to explore the Demon Suppression Tower.

Armed and armed, they came to the Demon Suppression Tower!
