The diplomat added: "And they're immune to genetic viruses, you know? After being completely biomimetic, it loses its physical body and is basically immune to genetic viruses, which we humans shy away from. ”

"Scientists have been working on nanobots in order to prevent some ill-intentioned civilization from dropping biochemical viruses on our planet."

Level 4 civilizations are already capable of creating some specific genetic viruses. If there is a real ground war, it is not uncommon for some shells to be mixed with biological viruses.

If a biological virus spreads, it can quickly paralyze a civilization, and the economic effect can be much higher than that of a ground heat war.

There are several different ways to prevent these viruses, the first is to prevent the loss of the human genome, and if the aliens did not get the human genome, it would be impossible to study a professional virus. The second is to do a good job in internal prevention and control, biochemical work, and ultra-high temperature disinfection is required when flowing inside and outside.

As for the third point, study nanorobotic drugs of various defensive nature, accumulate experience.

People are doing some of this prevention work.

However, hemispheres do not have this problem, they cannot be infected by the virus. Therefore, on their battle star, there is no need for a complex biochemical disinfection room, and even some research in this area can be omitted.

Lao Yang took over the conversation and said meaningfully: "So when it comes to really fighting, they can be more open-handed, unlike us." ”

"They are natural soldiers, and even if the ship is blown up and the body is sliced open, they can survive for a long time. This kind of high-end bionic technology, do you want to buy a set? ”

Human biomimetic technology is still in the sufficient stage for the time being, and it is no problem to install an electronic eye on yourself and replace a leg.

It is absolutely impossible to completely replace the whole body, and human beings do not have this need, let alone the focus of research.

"Then why are they standing in the glass enclosure?" A girl suddenly asked, "Since the whole body is already biomimetic materials, are you still afraid of cosmic radiation?" ”

A boy answered: "This is not difficult to understand, even if there are biomimetic materials, the fragile brain must always be well protected, and an extra layer of glass cover is a layer of protection." What if there is a gamma-ray burst somewhere? ”

The girl asked, "But what does it feel like to have only one brain?" Many personal emotions are expressed by various organs in the body......"

"They definitely don't think the same way we do. We can't do what they do, can we...... It always feels weird to keep just one brain. ”

As we talked, the ship slowly descended to the ground, and everyone felt a soft "click" under their feet. The ship slid forward for another distance and came to a halt.

Many hemispheres were already outside, dancing and greeting.

While applauding warmly, the hemispheres kept looking at the spaceship of the new human civilization, and from the outside, the spaceship of the fourth-level civilization seemed to be nothing remarkable. There are some round, lollipop-like bulges near the wings, which must be the legendary curvature engine, right?

The hemispheres who greeted them were all polite, but they just looked at each other, and did not talk to each other, and then raised their hands above their heads and made a "surrender" ceremony.

Of course, the meaning of this ceremony is not surrender, but the meaning of cordiality and friendship. I don't know why the original Gaia civilization was set up like this...... Maybe it's to raise your hands so that the other person can see that you don't have any weapons.

Lao Yang shouted in the earphones: "Everyone, put on your own power armor, we can go down...... Journalists take good records and don't forget their jobs! So what...... We should also follow this action, everyone should have learned interstellar etiquette, right? ”

"Got it!" The reporter's young lady smiled like a flower, and after she stepped off the spaceship, she raised her hands and stared at a hemisphere with a small eye, and then laughed again.

As a result, the hemisphere on the opposite side seemed to understand the kindness of this young lady and began to applaud at high speed.

Since it is necessary to make serious contacts, it is naturally not as utilitarian as the trading market, and it is necessary to directly start talking about conditions and interests, which will be more friendly.

After meeting the leaders of the hemisphere civilizations, the two sides first exchanged friendly and polite greetings, and presented each other with picture albums, sculptures and other artworks.

This was followed by a series of artistic and sports exchanges.

I have to say that the music of hemispheric civilizations is quite interesting, their brain modules can receive audio similar to humans, and the style of music is similar to that of heavy metal.

As for the sports aspect, there are more contents, playing black ball, table tennis, badminton and so on. The former is the entertainment of hemispheric civilizations, somewhat similar to rugby, and the latter two are human entertainment.

These are just very friendly exchanges, and you don't care about winning or losing. Of course, humans are actually a very competitive species, and many participants are working hard, but in this low-gravity environment, the human body is not able to adapt very well.

After three days, after such a process, the two sides had a preliminary understanding of each other, and then began the first phase of negotiations.

"It seems that everyone is getting along quite well?"

Before Lao Yang walked into the conference room, he chatted casually with his companions.

"Yes, there is a certain degree of similarity between the cultures of the two sides, and I think the ideological level is probably relatively similar. But the social system and the like, I don't know for the time being, so I won't express my opinion for the time being......"

Mr. Yang Fan of the Ministry of Foreign Affairs actually brought a little thought, first, he felt that this civilization was ...... Actually, it's okay.

In the previous contact, although a little procedural, there were some places of stupidity. But overall, they get along well with humans. It is difficult to disguise the content at the cultural level, and many things can be analyzed from the details.

Therefore, there should be no problem for the two sides to conclude some simple deals peacefully.

Second, he remembered the purpose of diplomacy this time, the new human beings need the specific history and ideology of the other party, and they also want to buy a complete set of biomimicry knowledge, preferably to be able to get a few people to study it.

Especially "genetic philosophy", this is the most important purpose of this trip!

Zhang Yuan nagged in his ear hundreds of times and thousands of times, which made him feel a little stressed.

This point, in fact, is a bit difficult, committing some civilized taboos. No matter how the other party is an interstellar civilization, it can't always be like an indigenous civilization that trafficks people to make a living.

Lao Yang secretly pondered: "The vast majority of interstellar civilizations do not sell human beings, and it is very dangerous to lose the genome. I don't know what this hemispheric civilization thinks......"

The new human race does not want to plunder the population directly through war, even if the other party is only a third-level civilization, if it really fights, the human race will still suffer some losses. With the current ideology of the new human society, it will not take the initiative to choose plunder, and there will be many opposing voices internally, and it is not worth it to be just a hemispheric civilization.
