Because the spaceship was already invisible, in addition to being invisible, everyone was more worried that it would launch an unexpected attack, so Officer Li decided to let everyone stay in the cave to wait and see what happened, and discuss the next step.

Since Xiao Ling had already fired just now, even if it was not invisible, it was obviously useless against this kind of iron pimple bullet.

In the end of the discussion, there were only two opinions that were more feasible, one was put forward by He Qiang, and the other was put forward by Wang Hui.

He Qiang's opinion is to use C4 directly to blow up and see if he can blow up a hole. But Yu Fei objected, saying that he couldn't even see it, and even if it exploded, he couldn't figure out the situation inside, and if a bunch of monsters ran out of it, it would be a big trouble.

And Wang Hui's opinion is that no matter how perfect something is, there will definitely be flaws, as long as everyone looks carefully along this circle of tunnels, they may find something, and if they can really find its flaws, it will be easier to think of countermeasures.

Wang Hui's method is very time-consuming and labor-intensive, and the only advantage is that it is relatively safe.

After discussion, the final decision was to use C4.

But then, the location of the installation has become a headache for everyone - how can you find the right place for the blast without even seeing the target? Moreover, there is also a lot of risk to worry about whether there will be any countermeasures on the surface of the spacecraft.

After thinking about it for a long time, Yu Fei's suggestion was unanimously agreed by everyone, that is, to use the butt of the gun to slowly send the explosives up along the cave wall, and when it could not be pushed, then fix it in that position, insert the detonator and detonate it.

No matter what you do, if you have a way and a plan, you will of course act quickly. It didn't take a few minutes for Yu Fei and the others to install it.

However, the result disappointed everyone - after the detonation, except for a hole in the cave wall, the spaceship was still invisible, and Xiao Ling also secretly checked it and found that it was undamaged!

Right now, there is only the stupidest method proposed by Wang Hui.

At that moment, everyone did not hesitate any longer, and the soldiers divided into two roads, starting to search carefully along the cave wall from both sides.

There are no absolutes in the world, and sometimes, the seemingly stupidest way is the most practical, and this conclusion is fully reflected in Wang Hui's suggestion.

The hard work paid off, and more than an hour later, Yu Fei and Zhu Ting's team found a very inconspicuous 'barrier crack' in the middle of the tunnel.

Usually, no matter how developed the technology is, there will be certain flaws to a greater or lesser extent.

The so-called stealth is just a kind of trick, and now, the most commonly used method in the military is to absorb as many radar waves as possible, so that the signal energy that can be reflected back is minimized, so as to achieve the effect of stealth.

And for the visual system, of course, the magic of light is used.

The crack was not large, just at the bottom of the side edge of the ship, two fingers wide and thirty centimeters long, and the real surface of the ship could be seen from here.

So, everyone immediately started experimenting, hoping to get something out of it. But almost everyone, including Xiao Ling, tried countless methods, but still had no effect.

Just when everyone was about to give up, Wang Hui quit, after all, this suggestion was made by him, so he scolded and said that he wanted to try again, not willingly.

Everyone is helpless, and they can only be dead horses as live horse doctors.

After tossing and turning for more than ten minutes, a magical scene finally appeared.

I saw that the cave wall was like a movie screen, and after a few flashes, the entire ship's hull exposed outside the cave wall was revealed!

Seeing this, everyone was ecstatic and high-fived in celebration.

"Holy, meatball, how the hell did you do that?" Xiao Ling smiled and gave Wang Hui a punch.

"Lao Tzu himself doesn't know, anyway, it's just a bit of foolishness." Wang Hui was also pleasantly surprised, scratching his head with a smile, and a little embarrassed.

"There is strength in numbers!" Officer Li smiled and continued, "All we have to do now is to find its entrances and exits!" According to what Yu Fei said before, I think it is most reasonable for us to go directly to the fork in the road where the metal sand disappeared! ”

At this moment, everyone was in a good mood, and of course they immediately agreed.

With this experience, under the arrangement of Officer Li, as soon as they arrived at the fork in the road, everyone began a careful search around like hunting dogs.

However, half an hour passed, and there was no gain, and everyone's hearts suddenly cooled.

Xiao Ling looked up at the iron bump protruding from the cave wall and thought for a moment, then said to Officer Li: "Officer Li, this thing is so high, we have already carefully reviewed the lower part, is there any need to check the upper part?" ”

"I want to, too, but we don't have the right tools in our hands, what can we do!" Officer Li smiled bitterly.

"It's really not good, let's use people!" Wang Hui smiled.

"Meat ball, Lao Tzu is the most convinced of you!" Xiao Ling gave him a thumbs up and said with a wicked smile: "Although I thought about it, your physique is the most suitable as a foundation!" ”

After that, ignoring Wang Hui's scolding, Xiao Ling discussed with Officer Li and others how to pile up people.

In fact, this method is similar to building a human ladder, the only difference is that it is not built into a surface, but into a cone.

Officer Li gathered all the special police together, plus Liu Can and Wang Hui, and gradually decreased according to their weight from bottom to top, and Xiao Ling stood at the top alone.

In the end, more than a dozen men built a three-story 'human pile' in the tunnel, and the location was of course chosen closest to the side edge of the ship.

Then, Xiao Ling began to carefully search the surface of the ship's hull.

But after looking at it for a long time, he still didn't find anything unusual, so he muttered a little in his heart: Isn't this the real entrance and exit location?

In the crowd, except for Wang Hui who began to urge Xiao Ling, everyone else has been biting and holding on.

In fact, this is not to blame Wang Hui, he is not only obese, but also rarely exercises, so his endurance is relatively limited.

After Wang Hui's urging, Xiao Ling was not only a little discouraged, but even began to be irritable, and immediately prepared to go down.

At the moment when he lowered his head, the corner of his eye seemed to be 'blocked' by something, and his heart moved, and Xiao Ling turned his gaze back. After a closer look, he couldn't help but feel a burst of ecstasy in his heart, and then he rushed down and shouted: "Hold on for a few more minutes, I found it!" ”

What Xiao Ling saw was actually an extremely inconspicuous white line-like substance, no more than two millimeters wide and no more than three centimeters long, as if it had been squeezed out, and it was impossible to discover its existence if he was not careful.

The reason why Xiao Ling shouted to tell the result was because he could see at a glance that this thing was not on the hull at all!

In order to see what it was, Xiao Ling got closer.

Soon, he smelled an extremely familiar fragrance - Nima, which turned out to be chewing gum! It's still minty flavored!!

Don't think about it, this thing must be a deliberate mark left by the inner ghost who sprinkled metal sand!

The reason why it appears on the surface of the hull in this form means that it must be a door.

Following the direction in which the gum was squeezed out, Xiao Ling soon found an extremely thin slit.

That's right, this is it! Xiao Ling was overjoyed in his heart.

Looking at the location of the gum again, Xiao Ling felt that this person had not left it here to identify the location of the door, and it was likely that he had also pointed out the location of the switch!

Without thinking much about it, just like when they were tinkering with the 'barrier crack' before, Xiao Ling used a disposable bamboo chopstick to poke around the gum one by one.

When he poked twenty centimeters to the right side of the gum, he felt the chopsticks suddenly sink inward, and then he heard a sound of mechanical transmission.

Bingo!!

Hahaha, it's finally done.

Xiao Ling was overjoyed and immediately burst out laughing.

"Hold the grass, did you really find it?!" Liu Can in the underground shouted.
