What Lin Xiao saw was its abdomen, which was very rough and covered with deep concave horizontal lines, and from the bottom up, the edges could not be seen at all.

This is that the pilot is very intimate and controls the spacecraft and starts to move to the side and upwards. Soon, the spacecraft was at a flat level with the behemoth flying in the atmosphere.

The whole of this behemoth also entered Lin Xiao's field of vision, and after Lin Xiao saw it clearly, he did not hesitate to say, "I'll go!" ”

He glanced at Lin Fengwei, who was also looking out of the window and frowning slightly, incredulously, and then looked at the old man, "Fish? ”

"That's right, it's a fish floating next to their ship.

It is huge, has no wings, and only has two fins that flapping from time to time, completely contrary to the laws of basic physics.

The dull and shrill sound they heard was the sound of the big fish.

Just then, another group of flying creatures appeared on the other side of the ship, and these looked relatively normal, with wings and air-waving feathers.

These creatures, which are supposed to belong to birds, are flying and hunting at the same time, but what they are preying on is a group of normal-sized 'fish'.

"This?" Lin Xiao was a little puzzled, and looked at the old man again.

The old man stroked his chin and smiled, "The stratosphere of this planet is very strange, the atmosphere is very thick, and the composition of the air in it is also strange. ”

"Well, this planet does not have the ozone layer of the parent planet, but this stratosphere has the effect of an ozone layer. Air is more than 100 times denser than the stratosphere on the parent planet. ”

Then, the old man pointed to the big fish flying outside, "And the creatures that live in the stratosphere actually have a low body density, and there is an air sac in the body, which can reduce the density even closer." In fact, they are flying, but for them, it is actually the same as ordinary fish swimming in water. ”

Lin Xiao understood this, and at the same time, he came up with a very strange thought, "Since the density is so thick, can that person 'swim' in it?" ”

"Of course!" The old man replied immediately, and then asked Lin Xiao, "Do you want to go out and play, this flying fish called Kun has a very gentle temperament." Just like singing, dancing, and playing with hairballs. ”

"Singing, dancing, playing with furballs?" Lin Xiao muttered strangely.

As soon as he finished speaking, the sound that emerged from Kun's body suddenly increased, and it originally sounded only a little sharp and heavy, but after hearing this sound at this moment, Lin Xiao only felt that the pores of his whole body were opened, as if a light stream of cool water rushed through his body, which was very comfortable.

Immediately afterwards, the kun suddenly began to flip, and such a huge body, even if it was just a random flip, still caused huge waves. It's just that the spacecraft is in an anti-gravity field, and the impact is not great.

A strange scene occurred, when the huge kun blew away clouds of different sizes as it turned, and clumps of hairballs about the size of a man appeared in some of the clouds.

These furballs were very strange, flying in the strong wind swept by the kun but did not retreat, and even accelerated towards the kun.

Soon, these snow-white hairballs landed on Kun's body and began to touch and fall off on the Kun, and Kun's body suddenly increased slightly, sometimes swinging its head, sometimes flicking its tail, as if it was really dancing happily.

The sound that came out of its mouth became lighter, as if it was very happy.

Lin Xiao was stunned, but he also saw it clearly. The so-called furball is actually a kind of bird, with legs, legs, and wings, but it is round when it is curled into a ball.

They bounce around the kun's body, and every time they jump, they catch a small insect from the kun's body and swallow it in one gulp.

"It turned out to be symbiosis!" Lin Xiao couldn't help but sigh, and then he understood why the old man said that this kind of kun likes to sing, dance and hairball.

"That's right, it's symbiosis. The kun provides food for these small furballs, and the small furballs clean up the kun's body. How about it, do you want to go up and have fun? ”

"Don't!" When the old man proposed again, Lin Fengwei's voice immediately came out. She said coldly, "It's important to get down to business, don't waste time." ”

"Little girl, don't be so nervous. This operation is like all expeditions, the first phase is no different from tourism. The old man smiled.

"Don't!" Lin Fengwei didn't overdo it, looking unhappy.

"Forget it, don't want it, just play it if you want to play in the future." Lin Xiao's face was solemn, but his heart was happy, how could he not know that Lin Fengwei was afraid that his fear of heights would suddenly attack.

After helping Lin Fengwei reject the old man's proposal, Lin Xiao asked curiously, "Kun?" It sounds like a strange name, but it sounds like I've heard it somewhere. ”

The old man brushed up his beard, and suddenly smiled and chanted, "There is a fish in the North Underworld, its name is Kun, the Kun is so big, I don't know how many thousands of miles it can ......!" ”

While listening to the old man's chant, Lin Xiao finally recalled that this was the "Getaway" written by the ancient sage Zhuangzi.

"This creature." After just a few words, the old man stopped, pointed to the Kun outside the spaceship, and continued, "Somewhat similar to what is described in the article, according to the ecological researchers of this planet, after this fish descends to the air below, its body will undergo an allergic reaction, the fins will be greatly accelerated, and the air sacs will also deflate and cause the body to shrink, and it really looks very similar to birds." ”

"But it's still a little different from the Peng recorded in the article."

"So amazing?" Lin Xiao couldn't help but exclaim. Although a lot of creatures have been discovered by now, and there are some alien creatures that are so magical that they seem to be in mythological science fiction, and new creatures are discovered every day. But Lin Xiao still felt very magical at this moment.

"yes, it's amazing!" The old man couldn't help but sigh, "So the scholars who have studied this planet have come up with a very interesting theory from Chinese scholars. ”

"If you associate the home planet, Luminous Confusion, with this planet, you will find a very interesting historical phenomenon."

"How?" Lin Xiao's mind was completely mobilized, and the old man's voice fell, and he couldn't wait to ask.

"In ancient times, the entire ecosystem was divided into three worlds, the human world, the earthly mansion and the heavenly court, right?"

Lin Xiao just nodded in accord, this was already a super ancient legend, and he had only vaguely heard it.

"You see, the home planet is earthly. And the surface of the Glowing Land is barren, the normal vision looks red, and the civilization exists underground, which is exactly the same as the legendary dungeon in the ancient times. ”

Immediately afterward, the old man pointed out the spaceship, "Look at this planet, it is rich, beautiful, with some unconventional creatures, and it all looks very beautiful." Civilization is below the surface. It is very similar to the legendary 'Heavenly Court'. ”
