The entrance to the passage is like a funnel, wide on the outside and narrow on the inside. In order to avoid unnecessary trouble, after entering the passage, Yang Yi left the "Tianjiao" with the personnel. Although the passage can still allow the "Tianjiao" to pass, the speed is much slower, and it is not as fast as Yang Yi and the others moving forward.

According to Yang Yi's requirements, the officers and men all wore protective clothing and used individual aircraft.

This is done to avoid the use of Origin Converters, which can produce Origin Fluctuations. If the one inside the shipwreckage that generated the Origin Wave is a small Origin Converter, and the guy who owns the small Origin Converter is still alive, he will be able to sense the Origin Wave outside. Although you can't turn off your own Origin Converter due to the use of protective suits and individual aircraft, you can't completely eliminate Origin Fluctuations, but you can minimize Origin Energy Fluctuations. Avoid being detected early. If there was indeed a powerful existence in the wreckage of the battleship, even if Yang Yi and the others were not discovered, they would still encounter each other in the end, so Yang Yi did not intend to hide it from the world.

Fortunately, confined spaces are similar to outer space, with no air and no obvious gravitational field, and the speed is not slow when using a single aircraft.

Soon, Yang Yi and the others approached the wreckage of the battleship.

Although there is still some distance, Yang Yi and the others are still shocked in the face of this ridiculously large wreckage. Seeing in reality and seeing on a screen are two very different things, and there is no comparison at all. Although the Human Federation also has SSS-class warships, it still looks very small compared to the battleship in front of them, even if it is only a broken wreckage. This is indeed an SSS-class battleship that can only be built by a top civilization.

How big is this battleship?

Obviously, Yang Yi didn't know either, because now all that was left was the wreckage.

The passage is about a kilometer in diameter and is not only completely filled with debris, but also severely deformed by compression. The edges are even compressed into solids under the action of a strong external force, and they cannot be seen at all. As for how long the battleship was, it was even more impossible to know, because Yang Yi couldn't see it, and the probe also searched a small area at the tail of the battleship.

"Major, ten kilometers to go."

Hear Aaron's reminder. Yang Yi began to slow down.

Although there were still ten kilometers left, the wreckage of the battleship had already filled Yang Yi's field of vision, and it looked like a steel wall blocking the front.

Of course, the battleship was not made of steel, the hull was made of a special alloy that was a hundred times stronger than steel.

At this time, a ray of light for navigation appeared on Yang Yi's helmet screen, and the other end of the light was on the battleship, which was a gap in the hull of the battleship. This is the navigation information provided by Aaron, which appeared on the helmet screens of all officers and soldiers at the same time.

Under the leadership of Yang Yi. The team flew towards the gap.

Because the wreckage of the battleship is so huge, it looks close, but in fact there is some distance. Of course, the gap does not look very large from a distance, but when you get closer, you can see that the gap is actually very large, enough for the "Ice and Snow Tiger" to pass through in the form of a fighter.

"Once inside, turn off the communication equipment. Everyone should be quiet, and there is no absolute need not to make a sound. ”

Yang Yi first turned off the individual radio on the protective suit. Other officers and men also turned off the radio station one after another.

If there is no air in a confined space, there is no way to transmit sound, and without using the original energy, you can only communicate with individual radios. Because it is a small communication device, it is not advanced, and it transmits information by electromagnetic waves. So the communication signal can be detected. If you use quantum communication devices, you don't need to worry, it's just that the Human Federation has not yet mastered the technology to make small quantum communication devices.

Entering the gap, Yang Yi turned on the searchlight.

The light travels in a straight line, and if it is seen by the enemy, then the enemy is already close at hand. Naturally, there is no question of revealing whereabouts.

Seeing the situation inside clearly, Yang Yi reduced his speed again.

It is clear that this gap was the result of an internal explosion, that is, a violent explosion occurred inside the battleship, and a powerful shock wave penetrated the hull from the inside out.

Behind Yang Yi, the officers and soldiers who followed the entry had dispersed.

Although it was a concentrated operation, Yang Yi had made arrangements before, after entering the wreckage of the battleship, Shen Chengwen's officers and soldiers would disperse to search the areas along the way.

Not to find valuable items, but to expand the search area in order to detect dangers hiding in the vicinity in time.

Of course, what to do, there is no need for Yang Yi to say more. The officers and men of the strategic squadron are often on duty and have extensive experience in this area.

Because the probe entered the wreckage of the battleship from here, and had already searched this area before, Yang Yi and the others found nothing.

Soon, Yang Yi and the others came to the first intersection.

It's a junction, but here there are several passages leading to different areas of the wreckage of the battleship, and the probes have already detected them.

"Major?"

When Aaron appeared, a structural diagram of this area appeared on Yang Yi's helmet screen, and each passage was marked with lines of different colors.

"Wait, you'll take control of the small probe we've unleashed, and we'll decide where to go when we're done searching."

"Understood."

Yang Yi didn't say anything more to Alundo, and gestured at Shen Chengwen a few times, asking Shen Chengwen to use the small detector he brought.

This small detector is only the size of a fist, can operate autonomously, send back the detected information in real time, and can enter many places that cannot be reached by people or large detectors, mainly to open the way when searching for unknown areas. Of course, small detectors are not omnipotent, the biggest problem is that the working range is very limited, only a few hours after charging, while large detectors can run for several days, some can even work for several years, and some can even run until the equipment is damaged. Due to this limitation, small detectors are generally carried by individual soldiers and only taken out for use when needed.

In a short time, Shen Chengwen and other officers and soldiers released dozens of small detectors.

Yang Yi and the others did not continue to move forward, but stopped. Of course, Yang Yi did not relax his vigilance, and asked Shen Chengwen to arrange officers and soldiers to be on guard nearby.

Actually, what to do next, Yang Yi didn't know what to do in his heart.

Previously, the probe released by the "Tianjiao" only discovered the original energy fluctuations, and did not reach the place where the original energy fluctuations were generated. Obviously, in the wreckage of a battleship with extremely complex structure and severe damage, not only could it not move in a straight line, but it was not necessarily the shortest distance in a straight line. If you go the wrong way, you will be delayed even more. It would be wise to wait until you have figured out the inside of the wreckage before deciding on the way forward.

That's where the small detectors come into play.

Small detectors can enter many areas that large detectors can't reach, so they can find a way for Yang Yi and them when there is no road.

By the time Aaron appeared, dozens of small detectors were already working.

Aaron projected a diagram of the ship's internal structure to the crowd, and showed the position of the small probe, as well as its path. In addition, Aaron is also using information from small probes to refine the internal structure of the ship's wreckage, which shows areas that have not been explored before. If necessary, Yang Yi can also ask Aaron to display the footage taken by the small detector with the camera. Of course, Aaron is also processing these image information in the background, and if there is a particularly significant discovery, it will be displayed for Yang Yi and others to know. Because there are dozens of small detectors, and each small detector has three 120-degree wide-angle cameras, even if Yang Yi and them all star, they can't find out the useful from so much information, so they can only let Aaron do it for them.

Fortunately, the light brain on the "Tianjiao" is very advanced, which greatly improves the speed of Aaron's operation.

Time passed minute by minute, and he didn't notice it, although Yang Yi was still calm and calm, he was a little panicked in his heart, he couldn't stay here all the time.

Using the information obtained, especially the structure of the area that had just been detected, Aaron made an analysis. The interior of the battleship exploded several times and was squeezed by external forces, causing the hull to be severely deformed, the interior was also severely damaged, and some compartments were completely flattened. These are normal phenomena, the internal explosion is likely to occur in battle, and the extrusion from the outside is related to the location of the battleship, that is, the passage is too narrow, and the battleship undergoes serious displacement under the action of the explosion, which produces a squeezing effect when it hits the passage. However, what is abnormal is that the main structure of the battleship, especially the load-bearing structure, was not completely damaged due to explosion and extrusion. It is precisely because of this that the wreckage of the battleship still maintains a relatively intact form. According to Aaron's analysis, under such a huge explosion and squeeze, even if this is an improved SSS-class battleship, it will disintegrate and even be blown to pieces. That is, inside the channel, the shock wave generated by the explosion will be enhanced after being reflected by the channel, creating a superposition effect, and the destructive power will increase exponentially. Even if the hull of a battleship can withstand the shock wave of the explosion, it will not be able to withstand the tremendous destructive force of the superimposed increase.

Obviously, the existence of the wreck of this battleship is itself an indescribable mystery.

Aaron is just an intelligent program and has no imagination, so the explanation it gives is that at the time of the explosion, the battleship was protected by some kind of external factor. As for what external factors are, Aaron didn't say, and he didn't know, it could be some kind of force, or it could be some kind of energy.

Of course, in Yang Yi's view, Aaron's analysis and speculation have little practical significance.

Now, Yang Yi only wants to find a route to reach the origin energy fluctuation, and the rest is not in his consideration.

"Major?"

Just when Yang Yi was about to wait any longer, Alun finally made a discovery, and a blurry picture appeared in front of Yang Yi.

It was captured by the camera of a small detector, and it was a little blurry because it was just a picture.

Seeing this picture, Yang Yi's brows immediately wrinkled together, and Lin Feng, Shen Chengwen and Yujiao also leaned over at this time. (To be continued......)
