What happened in North America naturally cannot be concealed from Fangzheng, who is located in space.

In fact, when Fang Zheng received Iona's report, his heart was unfluctuating, but .........

"What the hell is this?"

Fang Zheng was also dumbfounded when he looked at the pattern in the center of the North American continent on the satellite cloud map that looked like some kind of cult text and logo.

We are a ......... Sci-fi disaster movies are right?

What the hell is this?

Could it be that you went to the wrong set again?

In fact, after zooming in and seeing all kinds of devil-like monsters running on the ground, Fang Zheng even had some doubts that Diablo had also come here to look for trouble, however......... Doesn't that look like a demon in Diablo?

At least the human brain that looked like a horse had the limbs of a metal bracket and two barrel-like things underneath......... It's all sci-fi! There's no such monster in Diablo!

No, should it be said that it is a sci-fi demon style?

What a mess this is, what kind of bulls, ghosts, snakes, and gods are coming out!

Although he was very puzzled, he took this opportunity to take a closer look and found that something was wrong.

Now Fang Zheng has also noticed it.,Difficulty Nightmare IV is obviously equivalent to bringing together a lot of forces that invade the earth.,Originally, logically speaking,Maybe if you didn't kill the protagonist.,The other party may be attacking in waves.,But now it's become a nest out.。

Not only that, but these alien races, which were supposed to belong to different works, actually seem to have a very perfect unified mix. According to Fang Zheng's observations, if these alien races are really like the ones they remember, then they should fight.

But in fact this is not the case, they are clearly divided and cooperated.

The huge warship from the Heavenly Shatter Independence Day is obviously the Air Force, and Iona also reported that a strange alien fleet appeared in the Pacific Ocean to attack the naval forces in the Pacific, not only that, but on the North American side alone, there are alien forces that operate three-legged robots like giant octopuses, and the alien forces that shine blue light and can brainwash humans, plus the current appearance should appear in mythological ghost stories rather than science fiction movies......... Extraterrestrial ......... Person? Power.

There were times when these factions met each other, but there was no fighting between them at all, and on the contrary, each faction seemed to be doing its best to divide its own territory......... Well, this reminded Fang Zheng of Columbus's discovery of the New World.

It's not that you don't report it, the time has not come.

The Americans exterminated the native Americans and occupied their lands, and now the aliens have discovered their existence and launched an attack, and another cycle has come.

Sure enough, it is the reincarnation of heaven, and the retribution is unpleasant.

Let them toss and turn.

"The First Fleet continues to proliferate, and our goal is to fight to recover the entire Eurasian continent."

Fang Zheng completely gave up North America, in his opinion, as long as the Eurasian continent is preserved, North America is regarded as pig breeding, anyway, now those aliens in North America are crossing the sea to transform Americans into alien soldiers, and after the transformation, they can burn a little more.

Let's keep the pigs for now.

The most ironic thing now is that the only place in the world that can be considered peaceful at present, except for East Asia, which has entered the country because of the strong entry of the square blue fleet, the other thing that has not been swept away by aliens is the Middle East.

This is also normal, after all, Fang Zheng has never seen an alien invasion movie set in the Middle East.

From this point of view, the United States is enough to harm the whole world, and even Africa has a huge alien invasion army at this time.........

But even so, Fang Zheng is still quite cautious, he is currently sending to Earth is only the first fleet of the Blue Fleet, not even the main fleet, in fact, the main fleet is still hidden outside the solar system by Fang Zheng. After all, according to the urine nature of the system, assuming that these alien forces that should belong to different worlds and different races can unite to occupy the earth, it means that there must be a mastermind behind them.

Fang Zhengke still remembers that he read the trailer about the second part of Independence Day before he crossed over, as if it was said that the one who captured the earth in the first part was only a vanguard force and not the final boss, in fact, the same is true of the edge of tomorrow that Fang Zheng experienced before, and at that time, it was not all of the alien forces that attacked the earth, but only a small vanguard force.

This is normal, after all, the gap between civilizations is too big, like the square blue fleet, if it is placed in the world of Emilia or Louise, he also does not need to be fully dispatched, and even the founder does not even need to mobilize the main fleet, at most one plundering ship and two destroyers to solve the problem.

Of course, if it were to be on the safe side, another aircraft carrier would be pretty much the same.

The same is apparently true of these aliens attacking Earth.

Therefore, Fang Zheng decided to hide the main force and wait until the other party couldn't help but make a move, after all, whoever moves first at this time will lose.

And at this time, Iona gave a report again.

"Commander, an unidentified alien creature has appeared in Area A3 and is attacking."

“A3……… Huh? North Korea has aliens? ”

Hearing Iona's report, Fang Zheng was stunned for a moment, and then he was shocked.

Are you kidding me? North Korea......... Has North Korea ever made a sci-fi movie about an alien invasion?

No, in this case, it should be in a science fiction film made by the Americans, and then North Korea is set up as a location for alien scourge.........

Americans are really damn bad.

"Let me see."

As he spoke, Fang Zheng made a gesture, and soon, another surveillance screen was pulled in front of Fang Zheng, and then quickly zoomed in. It didn't take long for Fang Zheng to immediately lock on and gallop through the mountains, launching an attack on those villages to capture the traces of aliens who were humans.

They look a bit like octopus creatures on the outside, covered in silver-white armor, with only their backs revealing bright red flesh and tentacles.........

"Oh, that's it........."

Seeing this, Fang Zheng also suddenly realized, after all, he had also played games in his previous life, and knew what this thing was, you must know that Fang Zheng's favorite thing to do at that time was to pick up shells.

"Hmm......... If you look at it that way........."

Looking at the picture in front of him, Fang Zheng pondered for a moment, and then smiled slightly.

"Well, this is a gift......... Iona. ”

"Yes, Commander."

"Do a full scan of all the alien biota, put the information together, and think of it as a gift to them."

"Understood."

At the same time, in the underground bomb shelter of the imperial capital, people are still engaged in heated discussions. And the target of the discussion is naturally related to the silver-white strange fleet.

Although judging from the results, the other party obviously helped them resist the attacks of those alien forces, but they have not revealed their identities and have not tried to make contact, which makes many people, whether politicians or scientists, a little worried. While for now, the silver-white battleships clearly appear to be on their side, but that's just the appearance.

No one was sure if they were going to draw the ground as a prison, and they were just being raised as pigs in a pen.

"Is there still no response from the other party?"

"Yes."

In the face of high-level inquiries, the experts and professors of the Academy of Sciences nodded.

"We used almost all the means to try to communicate with the other party, but we still didn't get a response."

"So, do you think these strange aliens are good or bad for us?"

"This ........."

In the face of high-level inquiries, the experts of the Academy of Sciences suddenly did not know what to say, if it was okay, but why not communicate with it? Do you think it's unnecessary? But it's bad......... So if they do something to provoke the other party, the result will probably be even worse.

After all, even those huge alien warships that wiped out the entire city with a single blow were completely destroyed by the fire of these fleets, and it is conceivable that this fleet clearly possessed a superior power above that.

"Report!"

At this moment, suddenly, a soldier broke in.

"A silver-white battleship has come over our bomb shelter!"

"What?!"

Hearing this, everyone was taken aback, they hurriedly looked at the screen behind them, and at the same time, the screen also showed the outside picture, only to see that in the picture, a silver-white battleship was suspended outside the bomb shelter, and the soldiers in charge of defense were also very nervous, clenching the weapons in their hands, in the face of this unexpected existence, no one was sure whether the other party's intentions were good or bad.

"Shall we .........?"

"Don't panic!"

After drinking the commander of the guard, the old man at the head stared at the screen.

"Let's see what these guests want to do."

Soon, under the gaze of everyone, a white beam of light was projected from the battleship, and then a small silver ball fell from it, which looked almost the size of a basketball, and had no pattern on the outside, as if it were simply a ball made of metal.

After dropping the orb, the silver-white battleship quickly flew away, leaving only the orb suspended in midair.

Seeing this, everyone looked at each other.

What exactly is this thing?

Soon, the orb was immediately sent to a secret room in the bomb shelter under heavy guard, and at the same time, scholars and experts from the Academy of Sciences also came here to look at the orb in front of them.

"This ......... Is it just a round ball? ”

"No, in fact, ............"

The soldier guarding the orb replied with some confusion, and then he reached out and touched the orb lightly. Soon, I saw a map of the earth on the surface of the originally empty sphere, and not only that, but also the four colors of red, yellow, blue, and green respectively indicated the territory of each country in the south, east, west, and north.

"It's ......... What the? ”

Seeing this, the high-level couldn't help but be a little confused, could it be that this is some kind of puzzle toy given to them by aliens?

However, seeing this scene, some scientists' eyes suddenly lit up.

"It's a four-color conjecture! Sure enough, we guessed right! ”

"Four-color conjecture?"

"Yes."

Hearing the inquiry of the elders beside him, the scientist also hurriedly explained to him.

This was suggested by a British university student named Goodry, who wanted to ask what was the principle behind the fact that any map could paint a country with a common border in different colors with just four colors. Mathematically, however, the plane is arbitrarily subdivided into non-overlapping regions, each of which can always be marked with one of the four numbers 1234 without giving the adjacent regions the same number. ”

"It's really interesting."

Hearing this, the senior leaders were also quite curious, after all, they would not be exposed to this kind of cold knowledge, and it sounded interesting, but .........

"What does this have to do with this ball?"

"This is an exam question, and the other party obviously wants to use this method to confirm whether our civilization level is up to the level of dialogue with them, and if we solve this puzzle, then we can go further!"

"So, will we be able to solve this problem?"

Although the higher-ups don't know what the four-color conjecture is, they also know that if they can solve this puzzle, then maybe it will be the first step to communicate with alien civilizations!

"This ......... It's very difficult, to be honest, so far, the four-color conjecture has not been fully solved, and the previous four-color conjecture was our own choice of filling area, but this time, the other party has specified four basic standard points of red, yellow, blue and green, and we must complete the four-color conjecture on this basis, which requires the support of supercomputing........."

"No problem, from now on, all units across the country will do their best to cooperate with you to complete the task! Whatever you need, we only ask you to solve the problem in the shortest possible time! ”

For those who are excited, the top of the politicians think more, and perhaps for scientists, this is just an exam question, and after passing the exam, they can get the qualification to communicate with higher civilizations.

But what happens if you don't pass the test?

Will they be treated as savage creatures with no point in communicating?

As a civilization that has continued the tradition of exams for thousands of years, they know very well that "exams" are not just good things.

No, they should be considered a "temple test".

Just like the emperor came out with the couplet "A line of geese flying south", if you want to say "two roast ducks go north", it is definitely pulled out and roasted.........

Meanwhile, in the midst of the battleship, Iona remained duck-sitting, sitting at the table next to the square.

"Commander, does this make any sense?"

Iona looked at Fang Zheng suspiciously, the information collected by the Blue Fleet before had been completely stuffed into the ball, but what Iona didn't expect was that Fang Zheng actually encrypted the ball once before sending it over. In Iona's opinion, since it was to convey information, it would be good to send it directly, so why bother?

"To put it simply, it's a thrill, it's better than not doing anything at all."

Fang Zheng shook his head, he did this to follow the civilization contact method of the Forerunner clan in Mass Effect, and it can be regarded as a wake-up call to his compatriots in this world, after all, this is just a dog food world, Fang Zheng will leave after brushing, but he is not sure if there will be aliens in this world in the future. If Founder directly gives assistance and the other party accepts it directly, then maybe it will suffer a loss next time.

Just in case, it's better to follow the rules, which is good for both parties.

"Also, one more thing......... Commander. ”

"Huh?"

"In the Delta quadrant, Raffi discovered fluctuations in light-speed transmission information that communicates with the solar system."

"Oh?"

Hearing this, Fang Zheng raised his eyebrows.

"Let me see."

"Yes."

With Fang Zheng's words, Iona waved her hand slightly, and soon, the picture in front of her changed again, and then she saw that in the infinite starry sky, a square that looked almost as big as a planet, and an object similar to a Rubik's cube was heading in the direction of the solar system.........

"Is this .........?"

Seeing this, the color of the square front changed slightly.

Sure enough, the difficulty of Nightmare IV is not so simple.
