The military delegation and the technical delegation were put into work one after another, Ye Han and his soldiers were not idle, and after leaving the people to take care of the base, the others had to follow the two delegations to protect the safety of the delegates.

The so-called personal protection is actually a cover, and the real purpose of sending out the Marines is to buy time behind them when danger comes.

However, there were only seven of Ye Han's subordinates, and there were more than 20 people in the two delegations, and there were dozens of technical experts waiting in line to be airborne, and the pressure on the guards was not a little bit great.

Beidu also knew this, so he sent all the marines who stayed in Beiyuezhou to Ganymede, but it took time on the way, and he couldn't be in place for a while.

In this case, the military delegation offered not to be accompanied by escorts, who were also military personnel and had the ability to protect themselves, and the group of experts needed the protection of the marines.

As a result, the escort force was greatly tilted towards technical experts, but fortunately, the credibility of the resistance group was not bad, and the two sides were safe, and there were no problems.

The engineering ships sent by Beiyuezhou arrived at Europa at a rate of two to three days, bringing with them a large number of materials that Ye Han urgently needed, and the advance base was perfected at an extremely fast speed.

When the base was initially formed, Lin Yi drove the Yushan to parachute, and the landing section of the Yushan officially became part of the base.

Subsequently, several rounds of expansion of the base were carried out, and the final base was enough to accommodate 300 people to work and live, and the ammunition in reserve could be used for at least a week of continuous high-intensity combat, and the supply could last at least half a year.

The advance base is not only the residence of the delegation, but also the window of external propaganda, Ye Han is a layman in terms of publicity, but the political workers are all experts, under the strong recommendation of the political work group, the northern capital ordered the Yushan, Tianhe and several subsequent engineering ships to remove the main screen of the bridge and send it to the forward base, and the next day, these screens were hung on the outer wall of the base.

From now on, whenever an alien approaches the base, these screens will start on their own, looping various Earth scenery.

Aliens are not interested in the scenery of the earth, but they like human cities very much, and aliens who live underground all year round are particularly envious of human high-rise buildings, and are very interested in the spacious roads and endless traffic on the earth.

So the political work team adjusted the broadcast content in time, focusing on the broadcast of human city scenery, and later added the relics of civilization, the underwater world or something.

After some investigation, they learned from the resistance that the servants didn't know what entertainment was, let alone the concept of entertainment, so they came up with the idea, but they didn't expect it to work surprisingly well.

Gradually, the big screens of the base spread among the aliens, and more and more aliens came to admire them, and the political work team felt that the time was ripe and began to carry private goods in the broadcast content.

First of all, I put on a few concerts to test the waters, what classical rock, folk symphony, vocal music, folk music, orchestra, various styles and genres took turns, which shocked the aliens.

Music not only knows no borders, but there are no astral planes!

It was observed that the aliens had a high acceptance of classical and soothing music, and rejected rock, rap and other noisy things, so the political work team immediately adjusted the broadcast content to retain the audience to the greatest extent.

In order to strengthen the propaganda effect, Beidu also deliberately recorded a batch of songs sung in alien languages, the lyrics were all translated by Zeng Rui, and the awkward pronunciation and strange tone tortured the musicians on the earth to death.

It's a pity that the alien album failed in the end, not because the musicians didn't work hard, but because the pronunciation of alien was too weird, and it didn't fit with human music at all.

But you can't deliberately create a special music that doesn't conform to human aesthetics in order to fit the alien language, right?

It's not impossible to do this, because aliens have a much wider hearing range than humans...... But it's no problem to make it, and no one dares to guarantee whether it sounds good or not.

In the end, the matter was over, and the political work team still played those mature songs, and there was an endless stream of aliens who came to the base every day to listen to music.

The political work team was not satisfied with the achievements it had made, but made persistent efforts to launch a walkman business to aliens in a timely manner, using the method of hunger marketing, giving away a limited number of MP3s to aliens who came to listen to music, and providing music download and charging services.

The reason why it is given away in limited quantities is to create inequality among aliens, but what are the benefits of doing so, Ye Han has never understood.

The aliens' acceptance of music is a success for the political work group, and it also reminds the northern capital.

In the shortest possible time, Beidu came up with a cultural expansion plan, the content of which is to take human culture as the core, take the forward base as the carrier, and use human culture to assimilate aliens!

Anyone who knows about this plan is amazed, after all, the political work team has successfully recommended music to aliens, and it is not impossible to continue to erode aliens with human culture and human values.

So after the success of the music, the forward base began to work part-time in the cinema again, and first released two classic feature films to test the waters.

The dubbing of these two films was done by Zeng Rui alone, and the different voices of the characters are also very simple, just tune it directly with voice changing software.

As a result, the aliens are very uninterested and don't like feature films at all.

Beidu believes that this is the result of too much difference in civilization, and it is best to put a few aliens like to see first, and then put those with more connotation after slowly popularizing human culture.

But what kind of movies do aliens like?

The political work team got inspiration from the music and put two more song and dance films to test the waters, but the results still did not improve, so in a hurry, they simply took various types of movies to show them to see which one the aliens liked.

The result is quite unexpected, aliens actually like to watch fantasy movies the most, whether it is magic, fantasy, science fiction or martial arts, as long as it does not match reality, it is very popular, and the more it does not involve love, the more popular.

What a shocking discovery!

According to the analysis, aliens don't understand human living habits, and the servants are male and female, so there is no market for feature films at all, and all kinds of fantasy films can be watched even if they can't be understood, and it is normal to be popular.

The movie screened at the forward base also caused several episodes, one is that after watching the martial arts film, the aliens expressed their admiration for the ability of human beings to fly to the sky; Second, after watching magic movies, most aliens believe that there are several intelligent beings on Earth coexisting; The funniest thing is that after watching the Star Wars series, the resistance group took the initiative to find the political work group and carefully asked if humanity was a branch of a powerful cosmic civilization.
