I'm trapped in a cube

The clouds and fog became thicker and thicker, and the layers of white completely obscured the team members' sight, and they gradually broke away from the complicated emotions.

As the airship fell into thick clouds and fog, regular and pure cloud lines appeared outside the pod, extending into the distance.

"This is the trajectory of the turbulent flow. We need to find a stable flow area to allow the airship to continue moving forward."

There is a row of precision instruments at one end of the pod. A team member came to the instruments and observed them carefully.

After looking at it for a while, he decisively pressed the operating button next to the instrument.

After pressing the button, the trajectory of the entire airship changed. The airship, which was still rising, suddenly began to float along those regular cloud lines, as if a gentle current was pushing the airship.

Li Luo looked around for a while, but still couldn't find the power source.

"Do you feel it?" Zhou Chao asked from the side.

"What do you feel?"

"A gentle pushing sensation, like going with the flow."

"I feel it." Li Luo nodded.

"This is the power of the airship... In other words, the airship does not need power, it just needs to drift with the flow."

Zhou Chao looked at the clouds outside the pod and began to tell Li Luo...

Just like the atmospheric circulation on the earth, the sea of ​​clouds in the fourth layer of the abyss also has certain rules, and different areas will have different rules of circulation.

At first, humans only discovered that the empty island located by the beacon returned to its original position after a period of time. Although the trajectory was messy, it was repetitive, just like the orbit of a planet.

The routes of these sky islands were recorded, and humans found the rules of circulation.

"That's why beacons are so important."

The beacon can not only record the location of the sky island, but also map the circulation trajectories at different locations.

"The Hadley cell on Earth is where the air in the equatorial area is heated and rises. It runs northward at high levels and gradually turns to westerly winds. There is an airflow sinking at about 30 degrees north latitude, and it divides into two branches at lower levels. Heading south back toward the equator, the other branch moves north.”

"The same is true in the abyss. The center of the cloud sea where the sun can reach directly will spread to the surroundings due to heat, driving the airflow below to rise upward. The thick outer cloud belt will sink downward due to the drop in temperature, forming a shape like A fountain-like whirlpool of empty islands.”

"This circulation is called the Great Surge. It is the circulation with the greatest influence among the four layers. Other small circulations formed due to the phenomenon of empty islands and relics will only affect part of the area of ​​the Great Surge and produce regional turbulence."

The beacons on the sky islands reveal the movement trajectories of these sky islands, and their movement routes are basically in line with the circulation direction of the large spout.

What the airship has to do is to follow the current, fly along the big spurt, and follow the direction of the airflow, and it will soon reach the nearby monitoring station.

"Won't you fly to other places and miss the monitoring station?" Li Luo asked puzzledly.

"No, most of the monitoring stations on the fourth floor of the abyss will not move and are fixed at the same position. These positions are basically the nodes of the circulation. The monitoring stations also have a certain monitoring range. Once the people at the monitoring station notice the floating The airship will be captured.”

"Before we arrived at the monitoring station, the beacon signal should have arrived at the monitoring station. The people above calculated the time of our arrival based on the position of the beacon. They just had to wait and see."

With the support of huge data, it is not difficult to calculate the specific arrival time of a drifting object.

After hearing all this, Li Luo sighed and nodded.

Only then did she realize that human beings have been exploring the abyss using their best methods.

"Do you feel familiar? This is a way to calculate the movement of weather balloons. You must have learned it when you were in the third grade of elementary school."

Li Luo nodded: "Yes, a very simple calculation."

She recalled that when she was in elementary school, her teacher said very loudly to all her classmates.

"This lesson is very important! If you don't study it well, you may get lost in the abyss in the future!"

It turns out that what the teacher said was not groundless, and that knowledge will really be used one day.

The seemingly chaotic air-sea circulation is just a surging air flow under the influence of heat. As long as we summarize the rules and understand each condition, even the most complex circulation can be predicted.

The clouds and mist outside the window moved faster and faster. Unknowingly, the airship had been flying in the sea of ​​clouds for a long time, and the cabin became increasingly quiet.

Zhou Chao looked around and said to Li Luo: "Let's rest for a while. You must be very tired on the empty island..."

Li Luo nodded, came to the edge of the pod, and sat down against the wall.

Seeing this, Zhou Chao also found a place and began to rest.

Although their consciousnesses were very excited by the starlight, their bodies were very tired. They fell into a deep sleep not long after they sat down.

The airship swayed like a cradle, and the gentle air current lifted the airship into a more stable circulation route.

Mo Ling curiously controlled the cube to fly around in this simple pod, observing the returning investigation team members from time to time, and looking at the huge objects flying in the sea of ​​clouds from time to time.

One of the investigation team members kept looking at the flying cubes in a daze. He didn't come back to his senses until his companion patted him on the shoulder.

"What are you looking at?"

"Nothing, I remember when I was Bottle Cap, I accepted that Cube as my apprentice." The team member scratched his head and said embarrassedly.

"You accepted a relic as your apprentice?" His companion looked at the Cube in surprise.

"Well, my consciousness was a little fuzzy at the time, haha." He smiled awkwardly.

Mo Ling listened to their conversation and understood why the man always looked at him.

"It turned out to be Master Bottle Cap."

Thinking of this, Mo Ling controlled the Cube to fly over and gave a bottle of Coke to the team member.

The team member looked at the Coke on the ground and was stunned again.

However, he did not hesitate and directly picked up the Coke and drank it.

"Thank you." He said to the Cube while drinking it in big gulps, and then patted the Cube again, revealing nostalgia in his eyes.

...

The speed of the airship in the sea of ​​clouds was getting faster and faster, but it remained stable.

This airship made of special materials seemed to have a special stability. People staying in it could not feel the bumps at all. Not long after, many team members had leaned against the edge and fell asleep.

Several blurry huge objects passed by the window from time to time.

Mo Ling could see the edges of these objects, most of which were empty islands, and some floating stones that had not yet formed empty islands, but there were also some objects that looked very strange.
