Cao Ge embarked on the path of exploration, holding a small detector in his hand.

"Murphy, launch the spaceship, fly around the land, and measure the size of the continent." Cao Ge said as he approached a plant.

"Yes, Doctor." Murphy's answer came over the communicator.

"Buzz !!"

A loud jet sounded, and Cao Ge looked up at the sky, it was his space shuttle.

Looking at the space shuttle that was going away at great speed, Cao Ge was very calm, and then lowered his head again.

Cao Ge took the detection instrument similar to a pistol in his hand, swept at the red flower, and a green light shot out from the muzzle of the gun to reach the flower.

"Tick! No included organism detected and is being analyzed, please wait for ......"

Cao Ge straightened up and looked at the small screen on the back of the probe instrument, waiting for the results of the analysis.

For the creatures that are not included, the small detector in Cao Ge's hand can do very limited, and all he can do is compare him with the creatures of the earth.

After about a minute, the blue screen gradually appeared with text.

"Carbonyl organisms, capable of photosynthesis, are 80 percent similar to plants on Earth"

Cao Ge looked at the explanation in front of him and had a bottom in his heart.

The presence of plants on this planet indicates that the biosphere is stable and most likely suitable for human habitation, but he is talking about the Arctic, not those ocean areas.

The only bad thing is that there is no day and night cycle, either polar day or polar night.

This is not very human-friendly.

Cao Ge squatted down and reached out to stroke the stamens swaying in the wind.

Although he was separated by a spacesuit, Cao Ge still felt the swaying of the flowers.

Cao Ge stayed where he was for a few minutes, then continued to walk forward.

About a quarter of an hour later, Cao Ge came to a small lake, about two acres in size, which was irregularly curved.

The water is blue, unfathomable, blue to the depths, extremely black, like a bottomless abyss, and it looks very terrible.

Cao Ge lay down and pressed the probe head into the water, and after the sampling was completed, Cao Ge slowly got up.

"Wow~"

Just as Cao Ge was about to check the analysis data, a ripple suddenly appeared on the surface of the lake in the distance.

It seemed that something jumped out of the water, but because Cao Ge didn't see it for the first time, all he saw was a splash on the surface of the water.

"Aquatic creatures?" Cao Ge said to himself curiously.

With that, he slowly walked in the direction of the splash.

In this process, Cao Ge glanced at the detector in his hand, and the analysis results showed that the liquid here is water, which is similar to the water environment of the earth, which indicates that it is very likely that there are creatures similar to the earth in the water.

"Click!"

Cao Ge opened the button on his waist, took out a pistol from it, and slowly approached.

The calm surface of this calm lake is deceptive, and all complex things may be unwavering on the surface.

So under the blue water, it is very likely that there is a water monster staring at him somewhere, ready to strike at any moment.

"Wow~"

The calm surface of the lake set off a ripple again, and this time he saw clearly, it was a creature the size of a palm.

The creature was flat, with scales on its body, and at a glance it really wanted to be a fish, but whether it was a fish or not, he was not sure yet, and he had to test it before he knew it, but those things were not what he should do now.

All he should be doing now is to learn as much as he can about the planet, and as for studying biological diversity, it is not an urgent task.

Cao Ge withdrew his pistol and continued to walk forward.

What Cao Ge didn't know was that after he left, under the lake in front of him, a pair of eyes slowly appeared, it was a strange creature, about the size of a dolphin, with limbs, he looked at Cao Ge's departing figure, revealing a wise look.

"Wow~"

Soon, he sank to the bottom again, and the lake was calm again.

Cao Ge would not have known that if he did not leave and continued to stay, a third type of contact would occur.

………………

Another hour passed.

The Explorer shuttle flew around the air and finally returned to him.

Looking at the spaceship that slowly landed and finally stopped steadily in front of him, Cao Ge opened the hatch and walked in.

"Hiss~"

Through the two hatches, Cao Ge returned to the inside of the space shuttle.

"Dr. Cao Ge, welcome back." Murphy said.

"How? Murphy? Cao Ge took off his helmet and asked.

"This land area is 20,000 square kilometers, there are large areas of plants, no intelligent creatures have been found for the time being, and after estimation, it can survive hundreds or even thousands of people in the initial stage, and hundreds of thousands of humans can survive after it is fully developed." Murphy's analysis.

"Twenty thousand square kilometers?" Cao Ge muttered to himself.

This area is indeed not small, and according to what he sees now, it should not be difficult for a total of hundreds of thousands of people to live.

Seeing this, many people will definitely have doubts, 20,000 square kilometers can only support more than 100,000 people, which is too exaggerated.

In fact, it is not an exaggeration at all, this place cannot be compared with the highly developed earth of the earth.

The provincial capitals of the provinces are listed as a city, and there are tens of millions of permanent residents at every turn.

But these people are not fed by a single city, but through the whole country or even the world, and if the cities are isolated alone, they cannot feed so many people.

And today's planet, or an undeveloped primitive planet, is inferior to ancient China, compared to ancient China, the country has only tens of millions of people, is it acceptable.

So Murphy's judgment is very scientific.

"Murphy, what else did you find?" Cao Ge asked again.

"Doctor, during the investigation, Murphy didn't find anything out of the ordinary." Murphy replied.

"Hmm." Cao Ge nodded and said.

"Murphy, can you monitor the atmosphere for objects from outer space coming in?" Cao Ge asked suddenly.

"I can't." Murphy replied.

Murphy's answer was expected by Cao Ge, because the planet was a blank sheet of paper, and there were no electronic devices in the air, so what Murphy could explore was the electromagnetic signal within a radius of several kilometers centered on the spacecraft.

"In other words, Murphy, you can't tell if anyone has come to this planet."

"Yes, Doctor." Murphy.

"Oops, forgot about this stubble." Cao Ge patted his head and said speechlessly.

"Murphy, start the spacecraft immediately, locate the signal transmitter location, and fly back." Cao Ge said.

"The spaceship is ...... in launch"

"Hum~"

A scorching flame shot out from its tail, and the ship sped away, disappearing into the air in a moment.
