"Then you have to do the same!" Lin Wei said solemnly, "If we don't do this, our stay here will be a dead end sooner or later. And believe me, it is not as difficult as you think to catch up with the planet's rotation. ..."
The little man and his sister looked at each other, and then both nodded firmly.
Although it is not clear what the basis of Lin Wei's last sentence is, they both have unreserved trust in the eldest brother.
Lin Wei hovered in mid-air. After ten minutes of calculation and mental arithmetic, he took his siblings and flew out for a distance, then drew a long arc and started to cut in one direction. .
To catch up with the planet's rotation, it is not enough to rely on their own strength and the influence of the atmosphere. They must rely on the planet's gravity! The cut-in angle chosen by Lin Wei is an angle that can produce a "gravitational slingshot effect". Under the huge gravitational force of the planet, their three brothers and sisters will be faster and faster. If they are many times farther away from the planet, they can even be thrown out directly by the planet's gravity field like a slingshot and reenter space at a higher speed. However, they are very close to the planet at this moment, and this effect can at best assist them to accelerate to a certain degree to catch up with the planet's rotation.
Under Lin Wei's command, the little man and sister also let go of their resistance to gravity and began to let gravity pull themselves diagonally downward.
"Wow, it's amazing." My sister cheered, "I didn't expect that the speed can really become faster like this!"
The little guy is also surprised.
Lin Wei also had some pride in his heart, and he didn't expect that in this illusion, the knowledge he had learned before could actually come in handy.
The speed of their three siblings quickly surpassed one kilometer per second, but compared with the linear speed of the planet's rotation, there was still a big gap. Because of the size of this planet, the linear speed of rotation at this latitude exceeds three kilometers per second! At this time, they also fell some distance in the atmosphere. The surrounding air began to become dense, and the power of the airflow began to increase!
"Hold on!" Lin Wei shouted loudly, "Hold on for a while, and wait until our speed approaches its rotation speed..."
The little man and his sister Yiyan gritted their teeth and persisted hard.
After another period of time, their speed finally reached more than 3,000 meters per second. However, Lin Wei found a new problem!
The gravity of this planet is really much larger than the previous moon. Although their three siblings have caught up with the planet's rotation, their vertical speed has exceeded their expectations. Around their bodies, there has been a thick hedging air current, and the temperature of the body surface has risen rapidly!
"Ah, it's so uncomfortable!" my sister called out loudly, her brows furrowed, her face in pain.
"Use our flying ability to force a slowdown!" Lin Wei said loudly.
The three brothers and sisters showed their flying talents at the same time, but they were a bit late. They are falling too fast at this moment, and the gravitational force of the planet has greatly exceeded their expectations, it is like a bird on the earth, if suddenly it is in an environment where the gravity is several times and dozens of times the earth. , It must be unable to fly, and may even be crushed to death by its own weight! And their three siblings are now in the air, in a state of weightlessness, so what the planet's gravity affects is only their flying ability.
Can't fly! Lin Wei was shocked. According to his judgment, the flying ability can only ensure that the falling speed of the three siblings will not increase, but it is impossible to slow down the speed.
If this continues, they are likely to become three meteors in the atmosphere of this planet...
The wind rang in my ears, the surrounding air became denser, and the temperature of the body surface became higher and higher!
The younger sister's expression became more painful.
"Small man!" Lin Wei shouted, "Come here soon!"
The title of the little man is privately called Ju Xi, and he usually calls "the second brother" when there is a younger sister, but at this moment, he can no longer take care of this.
"Here." The little man Yiyan moved closer to this side.
"The two of us, protect my little sister!" Lin Wei said firmly.
The little man froze for a moment, hesitated for two seconds, and then nodded heavily.
So, the two of them hugged their sister tightly. In this way, only the two of them are in direct contact with the airflow; and the younger sister is basically in a safe environment surrounded by them.
"Brother, you..." My sister pursed her mouth, her eyes flushed.
For Lin Wei and Su Xi, this is an illusion, and their primary goal should be to find ways to clear this heavy trial! However, at this time, the two of them did not hesitate to abandon themselves and protect their sister!
why?
Just because it is our sister!
As the elder brother, isn’t it justified to protect his sister?
The three siblings continued to fall rapidly, and flames were already on the surface of Lin Wei and the little one.
Lin Wei and the little man made painful snorts in their noses, and they gritted their teeth and made their last insistence.
Can it succeed? How long will it take to reach the ground? At such a fast speed, even if you haven't been burned to death~EbookFREE.me~, you will be thrown to death the moment you fall, right? Lin Wei's brain thought vaguely.
Wait... Lin Wei's confused brain suddenly moved, blue...blue...could it be? !
Lin Wei opened his eyes hard and looked down through the flames and air currents around his body. Under their feet, there was an endless blue, shimmering and beautiful. The moment he saw the blue, his mind relaxed, and then he fell into a coma.
Bang! ! ! The violent collision was accompanied by a huge sound, and the waves splashed to a height of hundreds of meters, shocking more than a hundred seabirds in this area.
After about a few minutes, the three figures slowly rose from the water.
Lin Wei and the little man were all scorched and were in a deep coma, while the younger sister gently shook their bodies while wiping tears.
At this moment, two groups of halos suddenly appeared above Lin Wei and the little man's heads, shocking the younger sister.
"The second trial is reached." A Ruoruuowu voice sounded between the world.
