It's another sunny day!

The clear blue sky was filled with white clouds, like a blue glass dotted with pure white cotton.

Green mountains and green waters, birds singing and mountains are secluded, a scene of paradise. But today on the edge of the swamp it was a lively scene, crowded with people, and the noise was unusual.

Among them, the live broadcast car of the geographic channel is the most conspicuous, in addition to a field on the shore, more than a dozen monitors, connected to a variety of lines, and more than a dozen foreigners are nervously debugging the instrument.

It's Tom and Marryane and Morrow, they're busy. This time I used the underwater robot they brought, which is very advanced.

But before that, they plan to use drones to conduct an underground space survey to determine if there is an underground lake.

Xu Ling stayed with Professor Long and them, including Xu Bing, who was just watching in front of the TV monitor today, and did not come to the edge.

"How is it?, is the signal debugged?", the deputy director of the channel Zou asked the technician and assistant director.

"Okay, it's no problem. The technician signaled.

To the regret of many viewers, this is the third day of work, and there is no reason to ask for leave at all. Only a small number of people watched it secretly.

At this time, the students also beat their chests and did not dare to skip class anymore. The school has already released a word, skipping class again, and if you are caught, you will not be given credits, and you will retake it!

Therefore, although this advertisement was sold at a high price, Deputy Director Zou was a little uncertain in his heart, hoping that the ratings would not be too miserable, otherwise it would be difficult to do it next time.

However, thanks to the positive reviews of the last two times, this time it is very good in terms of family ratings. After all, there are many self-employed people and the elderly, and they are also interested in watching this program.

So much so that many netizens on the Internet left messages, saying that they would definitely not be stuck this time. There are also some schadenfreude, saying that the imperial court station broadcasts and sells advertising fees at a high price, which is estimated to have pitted advertisers.

Just when the Internet and offline were bustling, with Professor Long's shout of taking off, the exploration officially began.

Tom operates a drone with a wingspan of about two meters, carrying America's most advanced detectors, which can detect whether there is space below through a five-meter layer of dirt.

When a loud "buzz" sounded, the drone began to lift off with everyone's expectations, gradually moving towards the swamp.

As the drone approached the swamp and descended to a height of about a meter from the swamp, the following imaging appeared on the display. Pale black atlas, Tom shook his head, "It's silt, you need to move forward." ”

The camera will be aimed at the drone and the display, and the host will introduce the situation here, as well as the fossil museum that has been completed and opened.

In particular, the legend of the mysterious swamp and the video of the giant snake shot by Xu Ling were put on TV, and now almost everyone in the country knows that there are giant animals in this place!

It also made many people worry about whether there would be giant monsters coming out to hurt people.

As the drone flew out of a distance, the display began to change, and a faint gray color appeared, no longer gray-black. After Tom's explanation, everyone understood that the silt was beginning to desalinate and the water was increasing significantly.

"There is a situation!", just when the drone left the shore for more than 20 meters, suddenly the imaging instrument showed a different color, black!

Everyone looked at Tom nervously, they were also stunned for a moment, and then controlled the drone to stop slowly, "Sure enough, there is space below, which means that the space below should be formed by the lake!"

Hearing this, the members of the two teams raised their hands to celebrate, "yes", and many people in front of the TV and computer were also happy for them.

As the drone began to expand its scope of exploration, more and more clues showed that the upper swamp was not thick, but the lake below was very deep, and within a detection range of five meters, it was about 40 meters from the shore that could not be explored!

An hour and a half later, the drone circled the entire area of several square kilometers, and the results showed that the entire underground lake was deep enough to be explored by underwater robots.

When these words came out of Professor Sima's mouth, not only the tourists who watched the scene cheered, because they had a projector on the spot, which could clearly see the underwater scene, and they could also watch it in front of the TV and computer, but they had advertisements inserted!

The buzzing along the way, the drone startled a group of birds, occasionally you can see fish swimming in puddles, and even everyone can see a lot of snakes from the video, either fishing, or preparing to catch birds after camouflage!

Among them, there are some poisonous snakes with thick arms, which are very scary!

"Professor Long, the diversity of species here is really rich. Tom said to Long Hai.

"That's because you haven't made a trip to the mountains, these 100,000 mountains are known as the seed bank of China. Not only are known plants and animals, but unknown creatures are also discovered every year. Long Hai said proudly.

A small protective camera was lifted into a puddle not far away, where drone detection showed that there was less silt underneath and that access to the underground lake was relatively easy.

Then Marryane and the others brought out a half-meter-tall robot from a box about a meter high!

This Transformer-like robot camera is the workhorse. According to Marryane to the TV station, this robot has a certain intelligence, wireless transmission signals, can walk upright, can dive, propeller propulsion, and can judge whether to cross or move away when encountering obstacles!

This is already very surprising, underwater is not land, the most important thing is the waterproof problem, that is, this group of boys has such a great ability to buy this kind of underwater robot.

With the launch of the pump-type camera, not only the people at the scene held their breath, but the people in front of the TV and computer also did not blink, for fear of missing that wonderful moment!

Beneath the depths of water has always been a major place for human exploration. One is that human beings originated from water, and the other is that human beings are born with a desire for knowledge for the unknown.

For example, now, with the purchase of broadcasting rights from the imperial court station by foreign media, it is basically possible to watch it in places around the world that can receive signals.

What Deputy Director Zou didn't expect was that the domestic ratings were not even half of the last time, but the flowers bloomed inside the wall and the fragrance outside the wall, and the foreign ratings set a record!

This makes those businessmen who spend a lot of money on advertising very happy, and the domestic signals directly used by foreign online media are not even blocked from advertising.

As soon as the camera enters the water, everyone is greeted by muddy water, as is the case in most swamps. As the camera slowly sinks, there is more and more mud, and there is mud in front of the camera, and there is no line of sight!

Just when Tom and the audience think that this scene will last for a while, suddenly, the camera seems to enter another world! )
