Why did the temperature drop so much?

Needless to say?

Everyone who talked to Cheng Wanli, when they heard this question, their first reaction was to think of the CW-7 two days ago.

Could it be that Mather knew about the effects of CW-7 and released it on purpose?

Or, the pure effect of CW-7 also exceeded Mather's expectations?

But at the same time, in the next second, everyone felt that they were too conspiratorial?

"CW-7 was released once, so it shouldn't cause such a drastic global climate change, right? If it really has such a powerful effect, then does the existence of this refrigerant go beyond the scope of current technology?"

"But its effect is indeed exceptional, and the time of the meteorological anomaly follows immediately after its emission..."

"Does Mather know the real effect of CW-7, and is the relevant data he announced true?"

All ideas are supported by people. After listening to the opinions of these people, Cheng Wanli was actually undecided.

It's not that he's entangled in any conspiracy theory.

As a person who can distinguish between primary and secondary contradictions, he knows that the main contradiction now is not to find out what conspiracy is behind CW-7.

More importantly, how to deal with this disaster.

What he needs is to find out the real reason for the cooling of the atmosphere while dealing with the drastic climate change and avoiding huge losses caused by disasters.

If it is really related to CW-7, then he must get the real data of CW-7, and then prescribe the right medicine to restore the current situation...

Of course, the situation is urgent now, and these things cannot really be done step by step.

If he does this, he won't know how long it will be until he gets the real data.

Judging from the current cooling speed and scope, it is estimated that there will be more serious disasters soon.

He must use multiple methods at the same time, and compress the process by the way...

"I hope you will work with me to put pressure on them to get Mather to hand over real data."

This was the last sentence Cheng Wanli said to the others, and everyone readily agreed.

No one shirked.

And besides this appeal.

Many means of obtaining information, such as information warfare and espionage warfare, have been simultaneously activated by Cheng Wanli.

It is not necessary to wait for Mather to hand over the data, he can also get it himself!

After arranging the matter of CW-7, Cheng Wanli did not relax, and asked about other possibilities of causing the cooling phenomenon one after another.

Sun, geothermal, ocean currents, monsoons...

All possible directions have launched a convening order to conduct rapid research and tackle key problems, trying to find out whether there is any deep-seated reason for the cooling of the atmosphere.

At the same time, overnight, the cold and disaster prevention work was quickly launched across the country. People everywhere saw various disaster warnings on TV, on the streets, and in buses and subways as soon as they woke up.

wait until morning.

Cheng Wanli took the time to return to what happened last night.

"At present, we have proven that the blue streamer that appeared in the sky last night is essentially a kind of artificially created high-temperature plasma...it is not naturally formed."

It was Xu Chi, the leader of the temporary research team who spoke.

The team leader rubbed his eyes, feeling a little sleepy. The plasma flow just appeared yesterday, and within an hour, he was ordered to go to the scene to investigate.

As a result, I stayed there for half the night, and there were really no clues that could be obtained immediately, so I came back in the morning.

Of course, there are already people at the scene observing changes in gas composition and temperature.

Cheng Wanli thanked him for his hard work, and then said: "But the problem now is that someone who can create a plasma jet with a length of hundreds of kilometers is probably not on earth?"

Xu Chi paused for a moment, and did not answer this question. Instead, he took out a folded piece of paper from his pocket and opened it. On it was a line of calculation formulas:

"According to my calculations on the plane, these plasmas carry huge energy. They are not only high temperature, but also have the characteristics of high speed and high pressure, which shows that the environment they were in before is very unusual."

"How unusual?"

"I think they're very likely byproducts of nuclear fusion."

Cheng Wanli's expression moved slightly, his eyes fixed on the piece of paper in Xu Chi's hand.

Having said that, there is no need to say any more.

Nuclear fusion, and the ability to eject such a terrifying plasma flow, it is impossible for the people on earth to do it.

Unless there is a country on the earth called White Leopard...

"Apart from this, what information can be determined?"

"Is it possible that these ejected plasmas are a special weapon?" Cheng Wanli recalled the previous calls from other countries. Many people were worried that it was a secret weapon.

"Judging from the results, they do have a huge lethality. Now there is no substance that can resist their high temperature and impact. It is very similar to the plasma cannon in science fiction works, and it may also have the effect of weather attack." Xu Chi said.

"Eighty military drones took off last night, and most of them were damaged by the high temperature around them. Only two of them came close to observe the detailed situation."

"However, I don't think it's very likely," Xu Chi shook his head. "The energy required to launch such a plasma stream is enormous. At least one super-large fusion reactor must be dedicated to power it."

Xu Chi explained in detail how much energy is needed to launch such a "plasma cannon", and how advanced the design of the reactor is...

"But to use such a reactor to power a plasma cannon?"

Xu Chi picked up the ending, and shook his head again, sorry for his incomprehension, and even a little doubted whether his vision was too narrow.

It was also difficult for Cheng Wanli to understand, using such an advanced device to power a cannon?

What kind of Zenith star technology is this?

Wouldn't those aliens be the culprit for causing global cooling?

"Now it seems that in addition to global cooling, we have to face these aliens, and we don't know where their spaceships are docked."

Cheng Wanli was very sad.

But Xu Chi was stunned for a moment: "Spaceship?"

His whole body was like electricity passing through, and his hair was about to stand on end.

"You said, is it possible that those plasmas were ejected from the engines of alien spacecraft?"

Cheng Wanli didn't reply to him.

But Xu Chi's heart was pounding, and he felt that he had found the truth:

"Those plasmas have the characteristics of high pressure, high speed and high energy. Among them, high energy is attached to the fusion reactor, and high pressure and high speed are complementary!"

"If all the plasma can be ejected from one nozzle, then it will definitely be able to obtain a terrifying thrust!"

Xu Chi's eyes were piercing.

Chapter 385 A 150 billion-ton thrust engine?

"Spaceship engine?" Hearing this speculation, Cheng Wanli opened his mouth, and took a while to close it again.

In this short period of time, Xu Chi's thoughts had already turned around in that "spaceship", and he felt that his speculation was relatively reasonable.

Before, he was too fussy.

Not even the aliens would have the luxury of using a fusion reactor to supply a plasma cannon, because there's no need for that.

Using plasma cannon as a weapon is too inefficient and has a narrow scope of application.

Even if it can fly hundreds of kilometers, so what?

Replaced with a missile, it can fly tens of thousands of kilometers, although the killing effect of the missile may indeed not be as good as that super large plasma cannon.

But bombing people until there is no scum left is the same as killing people directly, isn't the result the same?

So even aliens should not use this kind of thing.

However, if this "plasma cannon" is actually an engine, or a plasma thruster, it will be different.

In the field of aerospace, the advantages and disadvantages of traditional chemical energy fuels are very clear, with high thrust and low threshold, but unfortunately, it is not a real man.

The fuel is injected too quickly.

If one is not well controlled, it will be sprayed out in a few minutes.

It's a total troll, and it's also a troll that can't be reloaded after the bullet is fired.

After all, the rocket and its engine were sent to outer space.

Therefore, it is generally believed that the potential of chemical energy fuels is limited, and only electric propulsion systems represented by plasma propulsion can help humans go deeper into space.

Now it seems that this path is really correct? !

Just last night, a stealth spaceship equipped with a plasma engine jetted forward over the city, so it can continue to appear over the skies of countries all over the world?

Xu Chi excitedly held a pen and paper, and based on the known data, he deduced the thrust of the engine that can eject a huge amount of plasma.

Cheng Wanli glanced at the formula, and probably knew what he was doing, so he didn't disturb him, but picked up the information and looked again.

Soon, Xu Chi came to the result.

"How?" Cheng Wanli also came over.

Xu Chi swallowed, "I don't seem to be wrong, do I?"

Cheng Wanli glanced at the last number on the paper and frowned:

"150 billion tons?!"

Is this really a miscalculation?

Is this kind of thrust really used to propel the spacecraft?

Facing Cheng Wanli's doubts, Xu Chi did not recalculate, but said with certainty: "I am sure I did not make a mistake in the calculation, and I have already calculated it based on very conservative data..."

Only Xu Chi himself knows that the parameters he chose are really conservative. Whether it is the estimated total amount of plasma or the ejection speed, he has tried to take the smallest, smallest, and smallest values.

Really too small to be small.

After all, they also observed the plasma flow last night and obtained some basic data.

If it goes any lower, it is a lack of respect for reality.

It's just that Xu Chi didn't expect to calculate this terrifying figure in the end.

This suddenly shook his previous thoughts.

Could it be that those plasmas are really just a weather weapon, or are they simply used to help them heat the atmosphere?

Cheng Wanli also knew that he would not see the result today.

After Xu Chi left, he immediately called his assistant and began to inquire about the on-site investigation. He wanted to see if he noticed anything strange when the vision occurred.

The assistant succinctly explained the local reports, and at the same time focused on a few: "Last night at about 10 o'clock, a rescue team that was trapped saw a strange convoy in the snowstorm..."

The assistant uploaded the surveillance video that was retrieved afterwards.

It can be seen that during the snowstorm, there is indeed a black and strange convoy driving on the road.

"The strangest thing about them is that the rescue captain at the time saw a male member of the convoy wearing a strange armor suit..."

"Then shortly after he got out of the car, the plasma flow appeared, but the man was not surprised at all, and quickly returned to the car."

Although Blizzard blocked most of the monitoring screen, Wang Lei's movements can still be seen roughly.

Cheng Wanli nodded and asked, "What else?"

The assistant operated on the computer, and soon pulled out more surveillance videos: "Also, according to the surveillance cameras, these people appeared and disappeared suddenly. Their car models, license plates and other There is no trace of any sign that existed before.”

"It's as if they only live in these few surveillance images!"

Cheng Wanli also clenched his fist unconsciously, "Did the captain feel any difference in the man who got off the bus?"

"No." The assistant knew what his boss wanted to ask, he shook his head and said, "I asked, and he felt that the other party was a bit silent."

"person?"

"I see."

"Send this message to several other countries that have also experienced plasma flow phenomenon, let them track it down and see if there is a similar situation."
