The ice worm arrived at the frozen lake, but the situation was completely different. When the ice worm encountered water, its originally round body immediately changed, and the circle was constantly elongated. In the end, it turned into a long worm with a thickness of a small arm.~~~~

In addition to the great changes in appearance, the second thing is that its movement is no longer a small jump. Its long body is spinning gently in the frozen lake, turning faster and faster. Later, its movement speed is not slow, almost reaching seventy kilometers per hour.

The ice worm is like a rotating arrow, and under the command of Li Feng, it keeps diving into the bottom of the lake.

However, Li Feng soon discovered the problem. Although this frozen lake is not big, its depth is really surprising.

As time passed, carefully calculated that the distance from the ice worm dived to the bottom of the lake was probably more than ten kilometers deep, but its bottom still seemed to be endless.

"I'll go, this frozen lake is hard to go all the way to the center of Europa, right?" Li Feng recalled the information about Europa, and then he was a little clear. The information said that it was indeed mentioned in the depths of Europa, and it was very likely that there was a lot of water. If this was the case, it would not be surprising.

With more patience, Li Feng was still paying attention to the ice worm diving down. He didn't know how long it took, but he felt that the depth was at least 60,000 meters long. Finally, the ice worm's efforts were still gained.

The environment deep in the frozen lake finally changed, but it was not finally at the bottom of the lake, but appeared in a headless sight, and the whole line of sight was full of water.

It turns out that the ground world under the glaciers is really full of water, and the ice layer on the ground is frozen to a thickness of tens of kilometers. It is amazing!

When he arrived at Europa's real groundwater world, Li Feng realized that humans actually had too little understanding of this satellite.

What is the only astral body that is most likely to have life?

This is not very likely, but in the earthly water world, full of endless life.

These lives are the three microorganisms that Li Feng discovered in the frozen lake before. They are very small, and the largest one is comparable to dust. But there are so many, almost countless, and there are endless troubles.

Li Feng even had an idea, or the entire underwater world of Europa, with their shadows in every corner.

In addition to the three microorganisms that have been discovered before, in the underwater world of Europa, Li Feng discovered the fifth life element, which are plants that grow somewhat like the Earth's cypress grass.

Their highest growth is only more than 40 centimeters, almost in the underwater world. They can also be seen, and they just drift with the waves at the bottom of the water.

They are even larger and provide billions of nutrients for three microorganisms.

Here, Li Feng finally saw an extremely united world of food chains. Cypress grass gave three newborn microorganisms a large amount of breeding nutrients, but the three microorganisms are the food sources of those invisible monsters.

Although Li Feng still couldn't see the invisible monsters in the water through the sight of the ice insects, their traces of the world under the water are everywhere.

Now, Li Feng finally knew why so many invisible monsters emerged in a small frozen lake.

Because this frozen lake is not a limited but fixed small lake. Its depth connects the entire underground water world of Europa.

After solving this question, Li Feng was slightly disappointed, because this was destined to prevent him from finding clues about how to deal with the invisible monster, but only solved the answer to the previous mystery.

After losing his target for the time being, Li Feng had to let the ice insects continue to dive into the underwater world.

He wanted to see if there is still a sixth life in the deeper part of Europa's water world? God knows how deep this water world is? What else exists below?

All things that have been straightforward are spent like this.

The aircraft in the air kept floating in the air, and Li Feng and the other two could only stay in the aircraft. When they were sleepy and when they were hungry, they would take two special nutrition pills.

This simple and boring life lasted for about half a month, and the ice worm, which was deserving of greatness, was also so simple and kept drilling down.

When they are tired, they turn into spheroids again and rest quietly in the water. The hungry ice worms come to the microbial community for a while to hunt.

After the 19th day, when Li Feng and the other two were almost exhausted, the ice worm finally dived to the bottom of the Shuiyang World.

But a black shadow appeared not far away, which finally made Li Feng jump from his bored state.

"What's wrong? Have you noticed it?" The roller polo saw this and woke up, and he quickly asked excitedly.

But Li Feng did not answer this guy, but he still closed his eyes again, shared his vision through the ice worm, staring blankly at the black shadow not far ahead.

The most unlikely thing happened actually happened!

In any case, Li Feng would not have expected that at the bottom of Europa's Ice Ocean World, there was a castle-like building.

Who had the ability to come to Europa early and built this majestic castle building?

The entire castle covers an area of ​​about tens of thousands of square meters. Judging from the style, it seems that this is not done by humans.

Similarly, Li Feng did not think that humans had this ability and built this castle under the water in Europa early.

Then there is only one question left. Did you encounter an alien building?

Although the aircraft that the three of them are currently staying in is also a product of aliens, Li Feng was still shocked when he saw a castle building related to aliens.

In this world, it turns out that there are really smart living organisms outside of humans.

After getting rid of it, he was excited in his heart. Li Feng hurriedly instructed the ice worm to crawl into the castle.

When he arrived at the gate of the castle, Li Feng found that the gate of the castle was not closed, but was allowed to be opened, as if it had been open for a long time. And looking inside the door, there was no sign of anger. It turned out that this castle was built by aliens.

But it has been abandoned for a long time.

When Li Feng learned of this situation, he was relieved, but somehow he felt a little disappointed.

But he quickly turned his attention to the two squat stone guards standing on the left and right sides of the city gate.

These two squatting stone guards are indeed not human appearance. They look more like lizard men, with a large lizard head and a human body shape.

Their height is roughly about 1.7 meters, and Shi Wei holds a pair of weapons that look like harpoons in his hand.

Alien civilization using cold weapons?

Li Feng was a little surprised, but soon, he overturned the wrong idea because he carefully pondered further that the harpoon's three-fork weapon actually had a square crystal of purple energy at the position where the harpoon's three-fork weapon was connected to the three-fork at the end of the handle.

Li Feng could see at a glance that these crystals were similar to the compressed energy blocks originally used on the aircraft, except that they were different in size and color.

Although it is just a stone statue, Li Feng is absolutely sure that if this is like the weapons of these lizard men, it is definitely not just the power of cold weapons.

"It seems that these lizard aliens are a kind of aquatic aliens. I don't know if they are of the same race as the lizard humans that once appeared on Earth." Li Feng said in his heart.

After looking in front of the door for a while, no one noticed that the ice worm, under Li Feng's instructions, crawled into the castle inside.

What happened next was that except for the two squatted stone guards, there were no more alien traces or discoveries in the entire castle, just as if the owner of the entire castle had emptied it.

After crossing the square in front of the castle, entering the castle, the only thing that Li Feng paid a little attention was the murals and reliefs on the castle wall.

These styles are indeed completely different from humans. This is indeed a castle built by aliens, because these styles are simply difficult to imitate or forge.

The real castle building is actually not big, and a hotel on the earth is wider than it. After walking around the castle for several floors, except for the relief and mural civilization that cannot be taken away.

Nothing was discovered.

In the end, Li Feng simply ordered the ice worm to continue to drill into the back garden of the castle. When the ice worm passed through an arch-shaped door, what he saw finally made Li Feng suddenly raise his spirit.

In the back garden of the castle, there are many deserted flowers and roots left. These flowers and plants seem to be both aquatic creatures, but no one takes care of them for a long time and have long turned into dead roots.

However, I don’t know what their essence exists. After so long, they have not turned into desolation. The traces left vaguely, but they still make people see their predecessors at a glance.

But what really attracted Li Feng's attention was not these withered flowers and plants, but a flesh-shaped cylinder standing in the huge back garden.

Because this flesh-shaped cylinder can move, it is actually the only creature that Li Feng has discovered so far in the entire castle.

But what shocked Li Feng even more was that the entire cylindrical building, like a cylindrical building, was about twenty meters high.

Around its body, giant spores were actually hung.

The appearance of these spores has a thin and transparent coat. Looking inside through this coat that looks like fleshy skin, they are one human-shaped creature after another.

They have six toes, three trident fingers, and convex eyes and cracked mouths, which are exactly the same as the invisible monster that Li Feng saw before.

At this moment, these monster fetuses were quietly staying in the sporophores. Li Feng looked around and there were dozens of monster sporophores hanging on the cylinder of the whole mountain. At this moment, Li Feng finally understood why these invisible monsters appeared in Europa.
