Not surprisingly, after entering the spacecraft, the separate cabin at the entrance was disinfected and sprayed with chemical mist.

After the poison was eliminated, Gu Lian took off the sealed suit, revealing the simple and light white clothes inside.

Lin Han looked at it again at this time, and found that even from the perspective of human aesthetics, her appearance can be called beautiful, and her facial features are like Asian-European mixtures on the earth, delicate and three-dimensional. Her long hair was jet black and shiny, and her amber pupils made her look quite mysterious.

Intuition told Lin Han that Gu Lian's age should be equivalent to twenty-eight or nineteen years old for an earthling.

The two of them were about to enter the spaceship from the independent cabin, but the bulkhead on the side suddenly sounded a rapid voice: "Gurian, trumble and grunt......"

Lin Han could only understand the first three syllables, that is, Gu Lian'an's name, and as for what was behind, he couldn't understand it at all.

Gu Lian was stunned when she heard this, and then she also muttered a few words, but the voice directly interrupted her speech, and replied a lot, her voice was hurried.

In the end, Gu Lian glanced at Lin Han for a few moments, then shook his head, and seemed to put back on the sealing suit with some reluctance.

It's really cautious...... Lin Han thought in his heart.

The hatch opened, and he was led by Gulian into the interior of the ship, and came to an empty, bright room that looked like a conference room.

There are more than a dozen aliens sitting in the conference room, men, women and children, all of them are light blue skinned, similar in appearance to earthlings, most of them are about two meters tall, and the women are slightly shorter.

They were all wearing sealed suits at this time, looking at Lin Han who was standing beside Gu Lian with both vigilance and curiosity.

Lin Han smiled and waved his hand: "Hi." ”

“……”

More than a dozen aliens looked at each other, and the last few hesitated to say "hi", and then they didn't know what to say.

The language barrier is incomprehensible.

Lin Han frowned secretly, thought for a moment, and then made a keyboard and mouse click, as if he was operating a computer.

He believes that with the level of technology of the other party, it is impossible not to know what a computer is.

Sure enough, when a young man saw his action, he suddenly showed a look of enlightenment, and quickly got up and ran out of the conference room, and soon came in with something similar to a laptop.

Actually, that's what a laptop is.

The young man put the computer on the table and turned it on, and Gu Lian on the side pointed at him and said to Lin Han, "Garn." ”

Then she pointed at Lin Han again, and said in a somewhat lame pronunciation: "Sweat." ”

The young man named Garn nodded, then pushed the notebook in front of Lin Han and stretched out his hand to signal.

Lin Han sat down at the table and looked at this genuine "alien laptop", his eyes flashed with a little surprise.

According to the screen of this computer, Lin Han realized that the vision of these aliens was different from that of humans.

If you are an ordinary human, you will only feel a flower in front of you when you see this computer, because many of the light emitted by the screen is not within the visible range of human light.

Fortunately, Lin Han is a five-color seeker who can distinguish 10 billion different colors, and the alien's vision obviously does not exceed this range.

He first looked at the keyboard, and then quickly found a symbol that looked almost exactly like the "1".

Lin Han pointed to the "1" and stretched out a finger, and Garn nodded knowingly.

Confirm the "1" on the keyboard, and the ten number symbols are confirmed - there is no doubt that aliens with ten fingers must also use the numbers in decimal system.

It turns out that mathematics is the universal language of the universe.

After the ten numbers are confirmed, addition, subtraction, multiplication, division, squarering, and so on are also quickly confirmed.

The mathematical symbol system was clear, Lin Han immediately took a pen and paper, first drew a schematic sketch of a planet and a satellite, and then wrote a gravitational formula according to the other party's mathematical expression, asking the value of the gravitational constant in the other party's measurement system.

What the value of the gravitational constant was, Garn didn't know, but an old alien on the side easily wrote it down, and it seemed that he should be a physicist.

According to the theory of relativity, quantum mechanics and other physical theories, Lin Han quickly knew the values of the gravitational constant, Planck constant, speed of light and other constants in the opponent's system.

At the same time, he also knew the other party's unit system.

At this point, Lin Han could barely understand the other party's mathematical and physical theories, and then after a rather difficult comparison, he saw the other party's key literature on classical mechanics, relativity, quantum mechanics and other theories from the computer.

Although the expressions are different, there is no doubt that the content of these documents is consistent with the academic works of Newton, Einstein and others.

In other words, Lin Han knew the meaning of these documents, and even speculated according to the formula, he also knew the meaning of many sentences. Now all he had to do was to deduce the meaning of each word based on that.

With his ability to read a hundred lines at a glance, Lin Han quickly browsed several documents, and the other party's language system gradually took shape in his mind. During this time, he also became familiar with the basic operation of computers.

After only an hour, he was able to use the other party's laptop without Gahn's help.

After another hour, Lin Han basically mastered the other party's language, Kellner.
