Chapter 68

On the edge of the colo islands, an island of about 89 square kilometers.

Xinghai, Lafite and many other tweets are busy on this island, and there are many devices and instruments in different shapes around them, which give the jungle a sense of technological world.

The island is the largest on the outskirts of the colo islands, and the initial site of the defense system is set on this island.

The reason why we chose this island instead of other islands is that there are a lot of trees on this island, which can effectively cover the people who are engaged in activities.

Although it is said that there will be no other humans or warships in this place in theory, it is always right to be careful. After all, what they are bringing out is a little ahead of the world.

There is only one kind of long-range artillery in the preliminary defense system, which needs ammunition filling.

In fact, Lafite's original idea was to make some energy weapons. After all, energy weapons are much better than loaded weapons in this kind of unmanned defense system.

However, in the actual operation process, Lafite has encountered many difficulties. First, ordinary energy weapons can't cause damage to sirens at all, because they don't have the rules of the world, so they can't be used at all.

When I wanted to make them, I found that they didn't understand the principle of these things. After all, they didn't touch these things. If it wasn't for the appearance of Lafite, they might never know these things. But even if they know now, they still need to learn slowly, which is useless even if they are urgent. In desperation, Raffi had to step back and discuss the method of this kind of loading gun with the tweets.

This is the field that chirps are familiar with. After all, their main job is to repair the ship's clothes. If they don't know how to use guns, let alone repair them.

After many days of discussion and experiments between Lafite and chirps, an experimental sample was finally made.

Xinghai looks at a double main gun not far away. He can't help but feel a burst of emotion. He didn't expect that Raffi would have experimental samples in just a few days. But now he doesn't have a clue. Although he doesn't feel frustrated, he still doesn't admit defeat.

This dual main gun was made based on the main guns of some warship girls. However, because it was not necessary to be carried by warship girls, it was supported by the main gun base on the ground, so chirp and Lafite made many magic changes to this main gun.

One of them is to increase the caliber and range of the gun, which is to increase the power of the gun. In order to deal with the danger of the blast chamber, Lafite added a lot of various devices to it.

As soon as the gun was finished, the tweets couldn't wait to give it a try. Of course, Raffi was also very looking forward to it. After all, this was her first time to participate in the production of this kind of gun. She used to complete these things alone, but now she makes them together with others, which makes her feel very different.

Because the defense system has not been set up yet, everything can only be used temporarily, but it's very troublesome.

It's just like the beginning of the port experiment, but it was rejected by Xinghai. The reason is that if the experiment failed, it would be bad to hurt other warships.

It's true that the new design mode and special device provided by Lafite will not have any problems in theory, but theory is theory after all, and there may be all kinds of problems in practice, so they agree.

But the actual situation is not what Xinghai said. The reason why Xinghai made this decision is that he always felt that someone was peeping at him in the harbor recently.

This kind of feeling is very strange. It's totally different from the feeling that the peacekeepers secretly look at him, and it's more appropriate to observe than to peep.

It's like he's a mouse in a cage, and there's an experimenter outside watching him every move.

Xinghai also secretly explored all the shipyards in the harbor, but found no problems. In desperation, Xinghai has to find Lafite, who has stronger exploration ability.

Lafite did not find any other people or the existence of the ship mother after testing the whole harbor area, but Lafite's sentence made Xinghai very concerned.

That is, although Rafi didn't find any unusual people, he found the siren breath in many places in the port area. This breath is very light. If it wasn't for Rafi's special ability, he might not have been able to detect it.

But Lafite's exploration shows a very serious problem, that is, there is a siren in the harbor area, and the siren's camouflage ability should be very strong, even Lafite can't find her trace.

Of course, if the siren appears in front of Raffi, it will be found.

However, since this siren has such strong camouflage ability and can sneak into the harbor area, its intelligence must have a considerable level, and it should belong to the advanced siren above the chess pieces.

But this siren has never appeared in the siren illustrated book, that is to say, this siren has never been found by others.Xinghai doesn't believe that this siren has only sneaked into his port area. Her skillful appearance is not the performance of a new diver.

With such a siren, no one will feel at ease in their own port area.

But Xinghai can't be too obvious. Although this siren may not be dangerous to Xinghai and Lafite, it is an extremely dangerous element for the shipwives in the port area.

If Xinghai pursues too much, it's not good to force the siren to jump over the wall.

The port defense device test is also the top priority. Naturally, it can't be found by siren, otherwise the effect will be greatly reduced.

So even if it's very troublesome to build a temporary fort here, Xinghai has to do so, because he has no choice at all.

Even though Xinghai and his party came here two days ago, they have not finished all the facilities until today.

Because we can't carry other shipwives, we're afraid that sirens will come in, so this time only Xinghai and Lafite, and of course the chirps.

As for cargo ships, they are ordinary cargo ships, and the protective measures are only good.

Moreover, Xinghai had not been idle before. He had explored the surrounding area completely and confirmed that there was no other person or siren here, so now they can safely and boldly experiment.

All the debugging work has been completed, and now we are just waiting for the command of Xinghai.

Xinghai reconfirmed that there was no other intelligent life around, and then said

"port defense device test, start!"
