When it comes to alien plants, most people instinctively think of the insect tree, that is, the kind that aliens sent to the earth, and only a few people know that the kind on the earth is actually just one of the insect tree family.

Ye Han is one of them, as early as when the First Fleet was on an expedition to Jupiter, he had taken a close look at the photos of Europa, when Callisto was still in global freeze and could not see its surface condition.

But by the time the Second Fleet arrived at Jupiter, Europa had become a lush, habitable planet with vast forests visible on the surface.

Combined with the captive logs, it is not difficult to see that after the failure of the first expedition, Europa quickly recovered, and the plants grew rapidly, covering the planet's surface in a short time.

However, at that time, the plants on Europa were still mainly white and brown, and the green was almost invisible, and continuing to analyze it in conjunction with the captive diary, it was likely that the aliens were preparing for the detachment of Europa, and they sowed a large number of insect trees on the surface of the planet, so that a large amount of food was harvested in a very short time, laying a solid material foundation for Callisto to fly to Earth.

Many biologists believe that although alien plants are not green, there must be something similar to the function of chlorophyll in their cells.

However, there was little market for this view, because Europa was still near Jupiter, where it received only four percent of the Earth's light, and the insect tree grew fast and well.

It can grow smoothly in the absence of light, and no matter how you look at it, insect trees do not rely on photosynthesis to grow.

According to human understanding of the biological world, the insect tree should be a special plant that grows by chemo-energy synthesis, but human understanding of living things is limited to the earth, and God knows if alien creatures have other ways to grow.

There are also scholars who study what happens when insect trees add chlorophyll, but before the results of this research are available, countries preemptively ban this research to prevent those scientific maniacs from creating new insect trees with unknown capabilities.

Since then, no research institute has been allowed to conduct research on modified insect trees, and this is still the case today.

But no one expected that after Europa recovered again, the first plants that grew on the surface of the ground were also green!

Now, a month later, Europa's plants are no longer the ones they were when they first sprouted, but have formed a lush green sea, with patches of grasslands and shrubs, and it is only a matter of time before the forests are large.

Li Shili looked at the vegetation all over Europa, and couldn't help but sigh for a while, there are snow-capped mountains and deserts on the earth, but there are green plants everywhere on Europa, if it weren't too short and not high enough, I am afraid that there will be more tropical rainforests than tropical rainforests.

It's not surprising to think that aliens are the best at tinkering with creatures, and what is the point of modifying a few plants that adapt to deserts or other extreme environments?

He even came up with an idea that he should never have appeared: if only he could get special plants cultivated by aliens, then the Gobi Desert on Earth could be turned into an oasis......

Of course, he is just thinking about it, the plants modified by the aliens must not have the problem of adapting to the environment, but should worry about the consequences of the alien plants invading the earth.

Again, the Gobi and the desert are now one of the important means for human beings to resist insect swarms, just imagine, if the Sahara Desert becomes a Sahara Oasis, how many giant insects can be raised? How many giant ants would have to rush into the oasis desert and make their way to North Africa?

Once upon a time, the Gobi Desert was an impenetrable barrier between human civilizations, and to this day, they remain an inconquerable territory for swarms.

This reminds Li Shili of a sentence: Feng Shui takes turns!

At this moment, an unusually conspicuous light suddenly flashed on the screen, this light came from the central part of the northern hemisphere of Ganymede, and from the perspective of the battleship, it was a lush grassland, and there could be no reflective substance.

Speaking of reflective matter, we have to talk about Europa, three-quarters of its surface is covered by water, and if you look at it from the right angle, the sunlight reflected from the water surface will be extremely dazzling, making it the brightest star in the sky!

This is not a joke, nor is it the Spring and Autumn penmanship of the literati, but the real fact - Europa is located 60 million kilometers in front of the Earth, the orbit around the Sun is extremely similar to the Earth's orbit, and the positions of the two planets have hardly changed.

On every clear dawn, early risers can see that there is an unusually bright star in the eastern sky, and those with good eyesight can even find that the star was just a small crescent moon at the beginning, and gradually became a semicircle with the footsteps of dawn, and the brightness became higher and higher, until the dawn of the day, its light was obscured by the rising sun.

And the brightness of this star is not always the same, sometimes it is brighter, sometimes it is a little darker, but no matter what time of day, it is much brighter than the morning star!

This star is Ganymede, and it is observed that its brightness is caused by rotation, the brightness of the land is lower when facing the earth, and the brightness of the ocean is significantly higher when it is facing the earth, and the brightest part is always only a line of moon, which is the sunlight reflected from the arc of the sea!

Venus is closer to Earth during its transit, but no matter what time it is, Venus is not as bright as Europa. This is because Venus is wrapped in a thick atmosphere that is not as reflective as the surface of the water; At the time of the transit, Venus is between the Earth and the Sun, and no matter how bright it is, it cannot shine brighter than the Sun.

So today's Europa is definitely the brightest star in the sky.

Of course, the brightest or the darkest is useless, and no one appreciates Europa's unique reflections, and everyone's first reaction when they see it is to immediately think of aliens and giant insects.

The reflection that Li Shili saw was not on the surface of the water, so it immediately caught his attention, and at the same time, the eyes of others were also attracted by the flash.

Just a few seconds later, the flash appeared again, and Ye Han frowned: "This is not a natural phenomenon, magnify this point for me!" ”

The bridge officer in charge of the observation immediately manipulated the equipment to zoom in on the screen, and the picture on the screen flashed several times in a row, and a grassland appeared on the screen, and several aliens looking up at the sky could be vaguely seen standing on the grassland.

"Go on!" Ye Han yelled suddenly.

The picture zoomed in a few more times, and the group of aliens occupied half of the screen, and everyone finally saw the situation there: among several aliens, there was an alien with an unusually short stature, and in front of him was lying on his stomach a giant insect larger than a grinding disk, and the shell on the back of the giant insect was crystal clear, like a brilliant gem, and it was still extra-large.
