In addition to inspecting the boundaries of the channel, Ye Fei also ordered the battleship to carry out a series of weapon exercises, and the results showed that the laser fired by the battleship's main gun would not be affected in any way, and the powerful crystal missile was basically not affected in any way - it was also a faster-than-light weapon.

In order to get the exact result, the God of War launched a total of three crystal missiles, although Ye Fei didn't have to pay for it himself, but it still made him feel very distressed, and he refused to live or die to realize the fourth one.

As for the solid shells fired by the electromagnetic cannon, it is tragic, at the location where the drone melts, all the shells will turn into a molten liquid metal in the process of flight, and after passing that passage, it will not be affected. A little further on, the shells flying out of the passage showed a noticeable deflection of bearing, flying a distance of 100 kilometers, and the deflection distance was 8 to 10 kilometers.

The rest of the part hasn't been tested yet, but this short distance alone is enough to choke, and no one can say what the situation is outside the passage, and how such a strange phenomenon can occur.

If it weren't for the Atlantean fleet not far ahead, Ye Fei would definitely have to send drones to find the answer.

Having said that, this place has been wrapped in the outer periphery of Atlantis for I don't know how many years, so have they never studied it? It is said that the Atlanteans have known the answer for a long time, but it has been concealed by the Atlantean leadership, and the Atlanteans captured by the expeditionary force on Earth will not have access to this core secret.

When he first came into contact with Periande, he mentioned the era of Atlantis expansion thousands of years ago, but he didn't mention the existence of the cosmic reef at all. It is impossible for Perian to be unaware of this, and the most reasonable explanation is that Perian did not want to tell humans about it at all.

However, since the Atlantean fleet strictly follows the direction of the passage, it means that even if they know the truth about the reef area, they will not be able to completely solve the reef area.

Thinking of this, Ye Fei secretly rejoiced, if there was no reef area, I am afraid that the Atlanteans would have expanded their territory in the direction of the solar system a long time ago, and before human civilization entered the cosmic era, they would have completely become vassals of the Atlanteans, and maybe some people would be complacent about it.

The collision between advanced and backward civilizations...... Ye Fei thought of the colonial history of the Americas and the bloody colonial era.

The cost of crystal missiles is high, but the cost of gravity guns is almost negligible. Ye Fei simply arranged for the fleet to conduct comprehensive fire reconnaissance within two light years of the exit of the passage. In order to speed up the efficiency of reconnaissance, the assault ships equipped with gravity guns were all separated from the main body, each responsible for a section of the passage.

The information obtained by the fire reconnaissance gradually gathered on the God of War, and the passage of the two lights slowly took shape on the hologram in front of Ye Fei's eyes.

The passage roughly coincides with the position of the captive. But the passages are only roughly connected in a straight line. Different locations in different lots. The shape of the passage is completely different, and if the shape of the passage were to be described in one hundred and fifty-ten terms, absolutely no one would have thought that it was a passage in the reef area. I would only think that it was an ant nest depicted by a boring person.

Fire reconnaissance has found at least dozens of relatively safe spaces for Ye Fei, the largest is larger than the earth, and the smallest is only a few dozen cubic kilometers of space.

In addition to connecting the main passages, these spaces are also connected to other safe paths, but Ye Fei does not have so much time to explore the specific situation of these branch notices one by one, let alone guarantee that he can reach the other side of the reef area through these passages.

If you don't consider the problem of faster-than-light flight, there is enough space in the passage to maneuver, but there will be a narrow "pass" every time you pass a distance, and the narrowest place is only a dozen light-seconds.

Ye Fei suddenly had an idea, the original plan was to place the fortress at the exit of the passage, why not place the fortress in those relatively large safe spaces? It is far more cost-effective to block the narrow pass and form a situation in which one ship can be closed and ten thousand ships cannot be opened, than to block the exit with a fortress.

Ye Fei is a commander who tends to attack, judging from other civilizations that humans have come into contact with, whether it is the Outer Bone Man or the Atlanteans, most of the cosmic civilizations are in a state of "attacking high and defending low", even if the Atlanteans have developed a protective force field, it has not changed this situation.

It seems that only the Disc Clan's protection is stronger than the offensive power, but the Disc Clan can only be regarded as an exception, and it cannot be covered by bias.

This point is vividly reflected in the war of the outer bone people, the human beings who have just entered the cosmic era rely on their super offensive power, and they have blocked the invasion of the outer bone people again and again with weak forces, even if it is a bone mound with a diameter of thousands of kilometers, they are constantly hating the human bombardment indiscriminately.

Even asteroids can be killed if they are killed, can a space fortress be built to be bigger than an asteroid? Wouldn't it be better to have the energy and resources to build more warships?

Therefore, Ye Fei never felt that it was a good idea to fix a motionless cosmic fortress at a certain key position, after all, no matter how thick the armor was, it couldn't stop the constant attack of the ants moving. Even if the Space Fortress is equipped with a large fortress cannon with a long range and super power, forcing the enemy's fleet to not get close at all, the enemy can completely use meteorite swarm impact or other means to benefit without cost.

The reason why he carried out the orders of his superiors in accordance with the orders was that he was not qualified to dictate the decisions of his superiors at all -- the current Minister of National Defense Xu Shijie can be called the first person in the military, but even Xu Shijie could not cover the sky with the military single-handedly, and such an important decision to build a fortress was definitely a decision made by the military bigwigs.

However, building a fortress in a safe space inside a passage is a different story.

The danger zone around the safe space has a natural defensive effect, and the fortress hidden in the safe space basically does not have to worry about the siege of the enemy, as long as you look in one direction, you can cut off the entire passage.

If you are worried that a fortress may be breached by the enemy, then simply choose a few more locations to build a few more fortresses, forming a posture of blocking layers of attacks, and no matter how powerful the enemy is, no race can understand guò - at least, with the level of technology that human beings are currently exposed to, no race can pass guò.

Moreover, such a large fortress is much more stable than a battleship, and it is completely possible to build complex antimatter storage equipment inside the fortress, and once the antimatter is a big killer, no matter how advanced the enemy's scientific and technological level is, it will have to stop.

Of course, with that high level of technology, it wouldn't take much time to get around, and there would be no need to use this dangerous passage, or care about the slightest nuisance in the reef area. (To be continued......)
