In fact, the subsequent explosion is actually very simple.

This cave is not a golden-armored monster that cannot be penetrated by swords. It can easily destroy the hole with an ordinary high-explosive warhead.

However, the difficulty lies in how to set up two cameras, namely, human-observing cameras and unmanned cameras.

Of course, there are no two cameras themselves, and the urine properties that can be summarized in three minutes just now through the long journey, this hole can really be cleaned up and finished in three minutes. It is even a bit creepy. It is really possible that it is a teleportation player like 173.

"Are you okay?" Lu Yuan asked Su Mei on the communication network. After confirming that the communication on her side was unobstructed, he decided to blow up the hole again.

"Don't look back this time." Su Mei warned him.

"I understand that a real man never looks back at the explosion." Lu Yuan said with a smile.

He pressed the launch button, then turned around and left, the explosion shock wave slightly swept across his body, the air wave of melted ice and snow.

But this time the road is long and there is really no turning back.

Step by step towards the ground effect aircraft two kilometers away.

"So what's going on now?" Out of the mentality of a real man not looking back at the explosion, Lu Yuan walked along the way and did not try to use the Transportation Commission to connect to the camera. Anyway, this was Su Mei watching the whole process.

This is a bit like the containment process, which means that at least the road is far away, Su Mei and John Smith are always staring at the surveillance screen, and even saying that even blinking requires advance notification.

"There is no situation for the time being, please take a look." Su Mei said this, pulling Lu Yuan beside her and sitting down. The relationship between them now and their father and daughter is really subtle enough, so they feel that it is not unusual to do anything.

When I looked at the screen from afar, there was a quiet and peaceful entrance to the snow. Because the light was very dark, some infrared temperature measurement images were used.

Judging from the normal images, they are basically dark. Before starting the live broadcast, Lu Yuan still considered whether to use the environment to light up.

However, considering that the process of human observation is a process of sensing light by absorbing light, and a certain amount of light will be reflected back, making people aware of the existence of the eyes.

So in the end, it is better to choose the original ecology, so that you can only rely on weak starlight and negligible moonlight as light sources, and basically rely on long-term exposure to obtain influence.

But overall, all the years are peaceful.

"How long has it been?" Lu Yuan asked Su Mei.

"It's only been an hour." Su Mei said: "We can now choose to take turns to observe for three hours, one whole day, or take turns to observe for half a day, and then see if it will disappear with a whoosh after stopping observation."

"And if there is such a cave in reality, it is definitely a super attraction, with tourists every day and tickets that are less than 500 yuan will not be allowed to enter." Su Mei said smoothly.

"No, I feel that this cave would have been bombarded to the end. After all, it would take one experiment to explode. Just looking at the cave, you would probably be able to exchange the return ticket." Lu Yuan received Su Mei's complaint.

However, both of them had a bit serious expression.

At present, the first time Roland blew up the middle of the cave by himself, Lu Yuan and Su Mei chose to return, and when they received the call for help, about three hours had passed, and the cave was restored in about three hours.

The second time Lu Yuan followed Roland's advice and chose to blow up the cave entrance directly, and then observed that there was no abnormality for three hours. In about three minutes when Lu Yuan turned around, he found that the entrance to the cave had been cleaned up again.

This proves that caves can recover as soon as three minutes.

As for the moment, Su Mei has been watching almost without blinking since Lu Yuan blew the cave, but the cave has not changed at all this time.

There is really that kind. As long as you observe me, I will show you motionlessly.

Just like the opposite of the cat that superimposes life and death.

"Okay, let's observe for twelve hours first." Lu Yuan said: "Although it's boring, we took turns to observe."

"After twelve hours, stop directly observation, but video recording."

"Okay." Su Mei replied.

The plan is always complete, but in the observation of Lu Yuan Su Mei John Smith's three people's rotational approach without blinking, the opening of the cave was motionless fully demonstrated the self-cultivation of a cave.

After all, it is true. A cave shouldn't kick all the blocked stones it blocks like a sneeze. Only a well-behaved cave can feel like a cave.

Twelve hours later, when he turned to the plan, Lu Yuan adjusted the camera to the recording mode, and the three of them began to sleep with their heads covering their heads.

Although I didn't sleep very peacefully, Lu Yuan dreamed that the devil was sealed in the cave. I accidentally opened the devil's box and combined with the previous false speculations about the world, I instantly remembered the classic cyberpunk novel. Will the bionic man dream of electronic sheep?

Yes, will you dream in the fake game world?

At present, Lu Yuan can really dream, and John Smith has dreamed for decades in his sleeping dream.

But after waking up, look at the video recorder again.

The hole still remained motionless.

This is the correct cultivation of a cave.

Then Lu Yuan and Su Mei John Smith looked at each other: "The next one is the most important moment."

Su Mei and John Smith couldn't help but nod.

"Switch mode and turn off the camera completely." Lu Yuan said, "The shutdown time is three minutes."

"Affect the order." The Transportation Commission heard the voice of approval, and then the screen in front of the three people was completely black.

This is the last observation mode. Since people watching and watching videos cannot trigger the refresh conditions of the cave, then there is only the third one, and no observation is observed at all.

The three of them held their breath for the past three minutes, waiting for the passage of time.

Tick, tick, tick.

There seemed to be an invisible pointer walking.

It was not until the Transportation Commission notified that three minutes had ended that Lu Yuan said, "Open the camera."

The moment the screen lights up again, the three people look at the influence in the screen.

I saw that the black hole surrounded by snow fields in the center of the screen was previously covered by gravel. This time, it once again exposed its passage to the earth to the center of the earth.

The three of them took a breath of air conditioning at the same time.
Chapter completed!
