Lulu said, "Okay, we'll study these later, now let's summon the drilling robot to speak." While drilling on the ground, the men from Company A of Company B of the 1st Battalion of the Expeditionary Force went up with me to check. ”

After giving the ground an order for the drilling robot to start drilling in the ground above the top of the cave, Dog No. 1 and Dog No. 2 stood side by side, also sticking a metal telescopic rod upwards against the edge of the small hole.

After the two big dogs adjusted their positions to each other, several horizontal hoses stretched out alternately up and down on the sides of the two metal telescopic rods, which were intertwined with each other to form a ladder.

The men of Platoon A of Company B of the 1st Battalion of the Expeditionary Force, led by Zhao Li, climbed down the ladder into the hole above in turn.

After the officers and soldiers searched for it, Lulu and Ami also entered the cave together.

Lulu looked at the large cave full of primates and was excited, as if she had been in a cave full of treasures, first carefully observing the various external features of the animals as well as individuals of different sizes, and then began to examine the murals on the cave walls.

Although the external high-definition camera of each person's helmet here has a video recording function, and when the time comes, you can combine a 3D panorama of the cave for subsequent research when you return to the base, but the effect of watching it on the spot is definitely very different.

After looking at the mural, Lulu walked over to the unburned bonfire and found a simple wood-drilled fire tool next to the bonfire, which immediately reminded her of a person.

During her first life cycle, when she was still interning at the American Institute of Biological Sciences, her mentor, David, once took her and her classmates to camp in Yellowstone.

By the big blue tent, Uncle David, who was kind and kind, showed everyone the magic skill of drilling wood and starting fire, which the children had never seen before, and the tools he used were exactly the same as the ones she saw in front of her, but now they were a little smaller.

"Maybe it's a coincidence, Uncle David, how are you doing now?" Lulu crouched by the campfire, silently thinking.

Ami, who had been following Lulu on guard, asked, "Commander, you said that if you set a fire in the cave, wouldn't they be poisoned by carbon monoxide?" ”

Ami's words also aroused Lulu's doubts, and she looked up and down the top of the cave and the four walls, and found that there was a hole the size of a basketball on the left wall of the cave more than a meter from the ground, so she walked over to check it and said, "Computer, turn on the wind and humidity sensors on my gloves." ”

With that, Lulu put her right hand into the hole, and the data obtained through the sensors showed that a stream of air with a humidity rate of 80% and a speed of 5.6 meters per second poured in from the small hole.

Lulu continued, "Computer, turn on the ultrasonic detector and see what's behind this little hole." ”

The data obtained through the helmet's built-in detector showed that the small hole extended seven or eight meters outwards and then diagonally below, there was a small dark river two meters wide, and the wind in the dark river poured in through this small hole.

At this time, everyone's headphones rang at the same time: "Report, I am the operator of the ground-drilling robot, the robot is about to arrive above you, please clear out twenty square meters of open space in the middle of the hole, after cleaning, please try to stay away." ”

Soon, the soldiers standing near the center of the cave took the initiative to start their work, dragging away the primates lying here and some debris, clearing a twenty-square-meter open space.

People also try to stand close to the four walls of the cave and look at the top of the cave together.

After the burrower gets confirmed, it only listens to "Click!" Click!! Crash! Crash! There was a sound, and pieces of rubble fell from the center of the cave roof, and soon piled up into a small stone mountain more than one meter high.

Then, a "buzzing" motor sound first came to everyone's ears, and then gradually became smaller, until after silence, a light shot from the top of the cave into the hole, illuminating a square circle of light at the bottom of the cave.

Paired with the driller, more than a dozen smaller cleaning robots line up behind the driller to quickly transport most of the debris discharged from the rear back to the surface.

When the drilling robot and the slag cleaning robot return to the surface after completing their tasks, it can be seen that a vertical patio has formed between the ground and the large hole.

Lulu looked at the two-meter-wide square opening on the roof of the cave and said, "Clean up the stones." ”

After the soldiers cleared the gravel in the center of the cave, Lulu continued, "Ground personnel, you can put the elevator." ”

A dark gray large jet vertical take-off and landing transport plane was waiting in a large open space on the ground, and a camouflage container off-road truck slowly drove out, and the truck drove to the newly opened entrance on the ground, and after facing the entrance, the container was slowly erected and lowered through the hydraulic arm, and finally its bottom completely covered the entrance.

Then, the engine of the off-road truck roared, and the elevator box at the bottom of the container was slowly lowered into the "patio", and the metal cable on the top of it was enough for the elevator to descend into a large hole more than a kilometer underground.

Two flat trolleys were also placed in advance in the elevator.

When the two-meter-wide and two-meter-high quadrangular elevator arrived at the cave, Lulu began to instruct the soldiers to load the primates, who were still asleep, back to the surface in batches on flatbed carts, and put them into another large transport plane, and then bring some primitive tools that she felt were valuable for research back to the ground.

Thinking that it was almost the same, Lulu asked the helicopter to lift a large rock and prepare to plug the opening of the patio before evacuating.

When people and various equipment returned to the ground and boarded one after another, this comprehensive fleet of harvested aircraft began to take off and return to Base 1 in turn.

The huge taxidermy that Zhuo Wu visited before, in fact, the first floor is the actual herbarium.

At the beginning of the construction plan, the building was used for the study of New World biology, and it is also the office and research location of the Proxima B Biological Science Research Institute, which was personally supervised by Joseph and now Lulu, with a total of five floors, each floor with an area of more than 5,000 square meters, and people call it the animal museum.

Over the years, the institute had only used the second floor of the building, and on the third floor, Lulu had just decided to dedicate half of it to the study of the 112 primates she had just caught.

When she ordered a large number of reinforcements earlier, Lulu had already asked the people in Base 1 to immediately rebuild the third floor of the zoo.

Earlier, the third floor was actually initially ready for use, with two rows of detachable iron cages arranged up and down in the animal holding area, including a large number of half-meter, one-meter-five, two-meter-five and even three-meter-five detachable iron cages, a kitchen equipment specially designed for processing food for live animals, and some research dissection tables, desks, chairs and enclosures for staff.
