The reason why an interstellar quantum wave communication instrument is described as one is because it is very small and can be attached to the mouth, similar to a mole.

This thing is just in case, to prevent the light watch on the wrist from breaking, but also to prevent the signal of the light watch from being blocked.

Generally speaking, the communication speed in the same planet is extremely fast, but if you cross different star fields, the speed will be much slower, and you need to transfer to each other, so the communication between different planets is not too frequent.

Sometimes if you encounter something urgent, you still need to transfer it, which belongs to civilian supplies, generally speaking, the military department and some special departments, and the nobles have other equipment.

Interstellar quantum wave communication uses photon wave communication technology, which is a technology between light waves and space transmission, which cannot be instantaneously propagated, but it is thousands of times faster than the propagation speed of light waves. It is basically possible to achieve a teleportation pause of no more than three seconds within the territory of the Tunguska Empire.

This thing is used in the military department, mainly to prevent it from being hijacked by interstellar pirates, and when the time comes, it can be used to issue a distress signal, although Li Nan can't use it, but this is the standard configuration of this military equipment box.

In addition, there is an energy shield, which is mainly to prevent some radiation waves that may appear in space and damage the human body.

There's nothing to introduce to the rest of the stuff, it's basically just some military weapons, but the weapons are made as small as possible, and they look either like toys or jewelry.

This pile of things, Li Nan didn't see anything applicable to him.

That protective suit is worn on the body like Ultraman, needless to say about the sense of shame or something, Li Nan only wears that thing because he has a hole in his brain, and the clothes on his body have good defensive ability, so why bother to find that guilt?

As for the light bullet, the ring does look good, but the power is too great. Li Nan felt that he didn't need to use such a powerful weapon, so he also put it away.

In the end, I just took an air cannon ring and wore it on my middle finger.,The power of this thing can be controlled.,And even if it's maxed out, it's basically not dead.,So it's still quite fun to play with.。

Don't look at the power of this air cannon ring, this is one of the top technologies in this military equipment box, because it has slightly involved some spatial knowledge.

Compressing air itself is not too difficult, even compressing air into bullets is not particularly difficult, but it is not too difficult to operate in a laboratory.

The real use of a ring to compress air bombs involves a very high level of knowledge, and the academic theory of space pressure is fully used here.

Space pressure is an extension of air pressure, theoretically speaking, the standard space pressure is quite small, after all, people have always lived in space, the whole universe is also in space, and the overall space pressure is very small.

However, as long as you set a very small space with extremely strong spatial pressure, and set the input and output points before and after the space setting, it is quite simple to use the space pressure to make air bombs.

It's just that the current application of this technology is not too mature, and the power of the air bomb produced is even worse than that of some thermal weapons in ancient times. It is estimated that it is used by the police who usually patrol the streets to disperse the crowd.

However, although the power is not high, Cayos still put this thing in, after all, in his opinion, Li Nan's cultivation planet has mastered space technology, if Li Nan can feel interested, and with a little research, maybe he can give something to me.

Don't mention any misunderstanding in the middle, anyway, Li Nan is quite happy now, after all, this thing has no power, and it is just right for him to use it on his own side.

The most important thing is that the role of this thing is similar to the role of props that appeared in an anime he watched when he was a child. There is inevitably a sense of unreality shining into reality, and the two-dimensional feeling of coming true.

After putting on the ring, Li Nan packed up the military equipment box and went out to buy tickets.

Didn't you say you were going to travel?

Although Li Nan can teleport over directly, but if he teleports over, there is no aviation record, which will easily arouse the suspicion of others, Li Nan is willing to work harder, but also try to keep his secret. Find one who is not a bad person, and meet two who are not bad people, but there is no guarantee that every one you encounter is not a bad person.

Although tickets can be purchased online, Li Nan hasn't been out much, and it just so happens that he has time today, so he simply went out to buy it in person in the store.

In order to ensure the relative integrity of the land and prevent subsidence, there is no subway on the Dixing side, so Li Nan can only take the maglev train when there is no car, don't look at the technology of this train is very old, but the safety and convenience are not bad at all, the most important thing is that there is no need to worry about traffic jams when taking this car.

One stop every three or two minutes, and it takes less than half an hour to arrive.

Here is the Interstellar Aviation Agency, where you can buy tickets for any flight equipment departing from the Emperor. In addition to buying tickets, you can even rent aviation ships here, as long as the money is sufficient, except for warships with large weapons and military weapons, the rest can be rented at will.

Of course, Li Nan won't rent this thing for nothing, and he won't drive it, so he honestly queues up to buy tickets.

Buying tickets here is actually not much different from buying tickets online, there is still no one to serve, you can just buy it yourself at the self-service ticket counter.

Li Nan calculated the time and booked a ticket for 8 o'clock in the morning the next day, it stands to reason that at 8 o'clock in the morning, he should already be able to sleep on the side of the star, and then he can come here to sit quietly on the tourist starship for more than two hours, and go to Leo Star to see the giant kun and the red brocade dragon that is similar to the dragon.

If necessary, it's also a good idea to buy some of the flesh of the sea beasts over there. These are all things that are about the same size as the legendary divine beasts, not to mention the flesh and blood, at least the blood and qi energy must be enough, and Li Nan has recently practiced some body refining methods and martial arts, and he needs qi and blood power as a supplement.

Originally, it was planned to supplement it with pills such as qi and blood pills, but now that it can be supplemented, of course, it is better to choose food supplements, at least these meats should taste good, better than a blood-smelling qi and blood pills.

......

Toroste's side is actually already doing experiments, and a few mecha company soldiers who have reached the verge of mutation collapse are volunteering to be experimental subjects on his side, anyway, there is no medicine to cure genetic mutations, Torostai said that there are better relief potions than soothing potions, so they can only come over as a dead horse doctor to see, it is best to be useful, and it is just a death if it is useless.
