The strange Sand Star creature walked slowly ahead.

Yuan and Smith followed closely with extremely light steps.

The natural environment of the oasis is relatively simple, and there is no ideal hiding place on the trail.

"We approach it slowly from behind, being careful not to make any noise." Hara gestured to deliver a message to Smith.

Smith nodded in understanding.

It can be seen that the two of them are still a little nervous.

First, due to the monotonous environment and wide field of vision, it is basically impossible to conceal tailgating. All they could do now was try to get as close as they could to this bizarre Sand Star creature and launch a lightning strike at the right time to contain it.

Yuan Chen and Smith were ready to rush forward at any moment, maybe at a close enough distance, maybe at the moment when they were discovered by the strange creature.

Second, although through observation, it was found that this strange creature was at least slow to move on land, and from the outside, this creature did look harmless to humans and animals. However, all this is just a façade, and Yuan Haochen understands that their move is indeed a bit risky. However, indecision and indecision will only miss the opportunity, the Earth is facing an irresistible crisis, and they must quickly learn everything about the Alpha Centauri system, and there is a good opportunity for now.

Therefore, in the history of the development of the earth's civilization, the first local "war" with extraterrestrial civilizations began......

The strange Sand Star creature did look tired, and its speed began to slow down.

However, he was still insisting on walking towards the outer edge of the oasis. As he approaches the outer edge of the oasis, the upper half of his body begins to sway from side to side.

"Not good!!"

Yuan Haochen had a faint bad premonition in his heart, and his intuition told him that this guy would find them soon.

Sure enough, the strange creature's torso twisted towards them, and then, as if it had seen a ghost, its body suddenly trembled, and all the savings in its upper body twitched violently.

At the moment when TA twisted around, the simple ultrasonic detector on Yuan Haochen's body reacted.

Of course, the lower half of this guy's body was not idle, and began to move violently, this intensity is only relative, in the eyes of Yuan Chen and Smith, it is simply pediatric.

It was too late, it was too fast, the pupils of Yuan Chen's eyes shrank suddenly, and almost between the lightning and flint, he kicked backwards with a force, and with the majestic reverse thrust, he flew towards the strange creature like an arrow from the string.

Smith's reaction speed was not slow, and almost when Yuan Haochen stepped out of the front foot, he had already rushed out.

In the end, Yuan Haochen was one step faster, he didn't leave time for the strange creature to react, and he had already teleported in front of him.

"Knock~" Yuan Haochen knocked him down with one kick.

Although Yuan Haochen had tried his best to control the strength of his feet, the strange creature still fell to the ground in embarrassment, waving its tentacles indiscriminately.

In just a few seconds, the first "war" between the Earth civilization and the Sand Star civilization was decided.

As a result of the "war", the Sand Star civilization was completely destroyed by the Earth civilization!

Smith was a step too slow to kick his turn, and the strange creature was already on the ground. At the signal of Yuan Haochen, he had to retract his right foot that was hanging in the air and was about to come out with a little unwillingness.

Yuan Haochen opened his mouth to say something, maybe thinking of the language barrier or some other problem, so he stopped talking again, just took a step back, and tried to show a non-aggressive posture.

The strange creature looked a little frightened, and he didn't dare to turn over, perhaps for fear of being kicked by Yuan Haochen and them again.

I believe that at this time, TA must have realized the huge gap in action between himself and the two monsters opposite.

"It's too fast, it's too brutal......."

Perhaps this is the current mental activity of TA.

"It seems that they will be scared and think, and they should have a certain amount of wisdom." After a moment of observation, Yuan Haochen had already come to a preliminary conclusion that the alien creatures in front of him were not simple.

"Smith, you go get the space rover over and bring me the precision ultrasonic instrument." Yuan Haochen continued to look at the strange creature vigilantly and said to Smith.

"It's okay for you to be alone, right?" Smith confirmed.

"It's okay."

"Okay, looks like we've caught a weak chicken." Smith teased in a cheerful mood.

Smith ran away quickly, and Hara continued to keep a delicate distance from the strange creature.

It was imperative to preemptively control TA as a last resort, otherwise he wouldn't want to fight with alien creatures in person.

The reason why Yuan Haochen wanted Smith to get a high-precision ultrasonic instrument was because the ultrasonic detector on his body had been responding continuously, and judging from the current situation, these ultrasonic signals could only be sent by the guy in front of him.

Moreover, Yuan guessed that TA was most likely using ultrasound as a means of communication.

Five minutes later, Smith drove the Quanyue space rover in a majestic manner.

Yuan Haochen was keenly aware that the guy who threw himself on the ground seemed to be even more frightened after seeing the space car.

"Here you go, high-precision ultrasonic instruments." Smith guessed with a puzzled look, "You want to use ultrasound to communicate with this guy?" ”

"That's right! I want to learn the language of TA! Yuan Haochen replied calmly, "Stay vigilant, you will notify Lynn again, let the satellite be on high alert for us here, and immediately issue an alarm if there is an emergency." ”

"Listen to your command." Listening to the command on the battlefield, Smith showed the excellent quality of a soldier.

What kind of language should earthlings and aliens use when they meet?!

Yuan Haochen naturally thought about this problem.

He was sure that the strange creature in front of him was using ultrasound to transmit information.

But there is one of the biggest hurdles to solve when you want to communicate with them.

It's the language!!

Yuan Haochen knew very well that if he met with aliens, the language he should use was most likely mathematics.

As early as the beginning of the 17th century, the famous Italian scientist Galileo Galilei believed that the language of mathematics was the key to interpreting the language of the universe. The Chinese mathematician Hua Luogeng once said that we can use two figures as a medium to talk to aliens, one is "number" and the other is "number-form relationship" (such as the Pythagorean theorem).

No matter how different the scientific civilizations in the universe are, they all have the same language - the language of mathematics. Mathematical language has the advantages of clarity, monosemy, compactness, universality, abstraction, logic, etc., and is an ideal tool for interstellar communication.

Why does the language of the universe use "number" and "number-form relationship"?

Because, no matter what form the extraterrestrial civilization takes, the rules of counting should be similar. (It is not excluded that there are differences in the mathematical laws of high latitudes, but the cosmic civilizations at high latitudes will definitely be able to understand the mathematical laws of low latitudes)

When aliens are counting stars and other things, the rules should be the same as on Earth. Of course, if they had 18 or 3 fingers, they would be 18 or 3 digits instead of human 10.

For example, the Pythagorean theorem: the square of the hypotenuse of a right triangle is equal to the sum of the squares of two right angles. The "number-shape relationship" of this natural shape is universal throughout the universe. Then we can use "numbers" and "number-shape relations" as the basis to express some complex operations and pictures, hoping that they can "read pictures" and understand what we mean.

Of course, if they encounter alien creatures that are still relatively backward in science, they may not be able to understand the "Pythagorean theorem", but there is certainly no problem in understanding the relationship between numbers. (To be continued.) )
