Lan Ruyu studied on the console alone for a while before entering the area code of the earth on the display screen.

On the virtual three-dimensional map of the ancient Earth that appears in the sky, yellow accounts for about 5 tenths, blue accounts for about 3 tenths, and green accounts for about 2 tenths.

Yellow is a desert, blue is a water, green is a forest, and some other colors represent other landforms.

Lan clicked on the lake closest to the oasis on the ultra-clear virtual map, and the aircraft began to operate.

"Okay, right?" Lan Ruyu turned her head to look at Panpan.

"That's it." Not too stupid, right......

"So I'm going to sleep? When you arrive, please wake me up, thank you," Lan Ruyu hugged Panpan and entered the bedroom.

Lanks: "......"

On the hand-shaking skills of the hand-shaking lord Lan Yiyu!

opened the terminal and sent a video-

"What are you doing? I'm so tired! ”

…

Lan Ruyu threw Panpan on the soft big bed, closed the door, and locked it.

The big hat that hadn't reacted rolled around on the bed, stunned, "What's wrong?" ”

"How's the soundproofing of this room?"

"Okay."

Lan Qiyu raised her eyebrows when she heard this, threw herself on the bed, and faced the big cat cub.

"Panpan."

"What's wrong?"

"Tell me, who are you?" Lan Qiyu looked serious.

"Huh? I am a mysterious messenger from the East, Nicholas Panpan. ”

"Tell the truth."

"It's really the truth."

According to the Federation's interstellar map, the First Galaxy is indeed to the east of the Tenth System.

"Hush." Lan Ruyu pouted, turned over and lay on the bed, picked up the big cat cub next to him and held it in his arms, "If you lie to me, you will die!" ”

"How do you die?"

"At least I want to kiss you bald and beat your ass red! Let you be humiliated to death! Lan Qiyu felt that she was very vicious!

As he spoke, Lan Ruyu closed his eyes.

Yesterday I was too late to catch up on dramas, and today I got up too early, and lack of sleep is easy to die suddenly. Especially the kind of people who go to bed at one or two o'clock at night and get up at seven or eight o'clock in the morning, Lan Niyu doesn't know how those people survive the day's study and work.

The speed of the aircraft is extremely fast, and it takes an hour to reach this lake, which is considered to be one of the top three lakes on the ancient earth.

The group got off the plane and slowly approached the lake, only to find that the dark blue lake shown on the map was light blue when they got closer to the scene.

Lan Yiyu scooped a glass of water with an instrument, and the water in the cup also appeared pale blue, indicating that it was not the reason why the water absorbed the corresponding wavelength of light and scattered or reflected the light blue. It's a problem with the water.

Lan Ruyu plugged in the instrument to test the water quality.

"Drip-"

On the display is the data of each element.

Lan Qiyu only understands a little, and there are some elements, factors, etc., which she does not know and does not understand, these should have evolved in the ancient earth in these 100,000 years.

"The Ki element is exceeded." Lanks spoke from the sidelines.

"You know?"

"I studied environmental engineering ......" because the environment of the ancient earth is extremely poor, Lanks chose environmental engineering when he went to study on other planets.

"The 'qi' element is extremely harmful to water quality, according to the federal standard for lake water, the qi element in each milliliter of lake water can only account for 1/10,000. However, the proportion of this water is close to 1 in 1,000. The content is almost ten times higher, which is so scary! Ordinary plants generally cannot survive in this kind of water with a high concentration of the element Qi. There are certainly no aquatic beasts in this. ”

"Hmm."

The first stop of the investigation was a dark door, and Lan Ruyu was inevitably depressed.

"It is not easy to grow ordinary plants in water with a high concentration of Qi elements, but some rare ores are usually condensed at the bottom of such lakes. It's not bad news, either. ”

The ancient earth lacked nothing but yellow sand.

Both water and mineral resources are scarce, and there is no such thing as one important and one that is not. Lose one and gain one, in this way, in fact, there is nothing missing.

A few people walked around the lake, and went to other places to measure the water quality, and it was still a high concentration of Qi elements, and even higher Qi elements in some locations.

"Let's go, let's take a look at the next place."

The next place was a forest, far from the lake, and the aircraft flew all afternoon.

By the time it arrived, it was already dark, the forest was dangerous, and Lan Qiyu didn't plan to go down immediately. Let's stay on the aircraft for one night.

Early the next morning, several people came to the edge of the forest.

Lan Qiyu looked at the forest with a huge density of trees at the edge in front of her, "There are so many trees here, but there are so many trees on the periphery?!" ”

The forest of the ancient earth is almost the same size as this forest, but the periphery is extremely sparse, and it is a normal forest with a gradual increase in the density of trees from the outside in.

"I don't know, let's go take a look first."

"Panpan, come here."

There was a lot of gravel on the outskirts of the forest, and she and Lanx were wearing special thick-soled hiking boots, which were not afraid of awkward feet, but Panpan's cat was different.

Thinking of the pink and tender little meat pad, Lan Ruyu couldn't bear to have dust on the little meat pad, let alone being caught by a stone.

She's going to be distressed!

Lan Ruyu followed Lanx with Panpan in her arms and entered the forest with many vegetation.

After walking for more than 20 minutes, the gravel under his feet decreased until it disappeared, and it became a field of leaves full of dead leaves.

Lan Ruyu, a person in his early 100s, can sink more than 20 centimeters when he steps on the leaves, let alone face the sturdy Lanx.

"There are too many leaves, it's like stepping on cotton."

"What is cotton?" Lanks in front was puzzled.

"A kind of crop that has disappeared, and you usually read more books but you don't read it, why don't you have any common sense at all?" Lan Ruyu felt that this scene was familiar, but the protagonist was changed.

Lanks was speechless, this is common sense??? It was written in the book???

"Be careful, watch the road, don't fall." Shen Panchi in Lan Ruyu's arms reminded.

There are so many leaves here, the light is too dark, and who knows what lies beneath the leaves.

Be careful.

Lan Qiyu looked around, and there was nothing except the towering ancient trees and some shrubs and countless layers of leaves. Not even a single beast has ever been seen.

"Will this forest be free of strange beasts?" Lanks asked.

"I don't know, even if there is, it should be a small alien beast." The vegetation here is too dense for large exotic beasts to move.

After walking for a long time, the light in the forest gradually became more open, the density of trees decreased, and the clearing began to grow.

"It's weird, isn't it supposed that the deeper you go, the denser the trees are? How is it that there are fewer and fewer here? ”

As Lan Qiyu spoke, he heard a cry and the sound of running.
