I learned that this castle under the water and ocean is actually the real origin point of the invisible monster.

In an instant, Li Feng had an urge to destroy the Roshan cylinder in front of him, and just as he was about to attach it to action, suddenly, he was quiet again.

I have to say that the ability of these invisible monsters really makes him excited, and if he simply destroys this biochemical cultivation nest, he always feels a bit violent.

But if it weren't for this, then Europa's invisible monsters would probably be endless, and no matter how you kill them, you can't kill them all.

For a while, Li Feng was in a dilemma.

How can I take this biochemical nest for myself? Even if it can't be turned into its own, for the time being, as long as it can control it and no longer breed these invisible monsters.

With this idea in mind, Li Feng once again carefully looked at this biochemical nest like a mountain of meat.

At this time, the dozens of invisible monster embryos hanging on it were still growing and shrinking.

Thinking of the law of conservation of energy, Li Feng knew in his heart that this biochemical nest had to provide nutrients for the cultivation of these invisible monsters at all times, so it had to draw enough energy supply from the other side.

So inside it, are there still some unknown channels for absorbing energy?

Glancing at the pedestal under the biochemical nest, Li Feng's eyes couldn't help but light up. The bottom of the biochemical nest was not a hard stone, but a damp piece of dirt.

Could it be that the secret of its energy source lies beneath the dirt?

Thinking of this, the ice worm quickly got Li Feng's new order, and it spun and moved its body again, but this time it did not continue to dive, but plunged headlong into a dirt field at the base of the biochemical nest.

As an ice bug. The way it spins forward is not just to rush, but more often than not, it burrows in the frozen layer of the iceberg and builds its own little nest.

If it was a very hard stone, the ice worm might not be able to burrow, but at the moment it spun and plunged into the dirt. Soon, a small hole appeared in the dirt beneath the biochemical nest.

And the ice worm also disappeared into the dirt, and as it drilled deeper and deeper, Li Feng's eyes became brighter and brighter.

Sure enough, just as he thought, under this biochemical cultivation nest, there were indeed complex and dense rhizomes.

These rhizomes don't look like the rhizomes of natural plants, but more like man-made. It was clear that this was indeed a biochemical breeding nest deliberately created by the lizardmen.

However, there are too many rhizomes, and they are thick and connected to the dirt everywhere, Li Feng wants to break these rhizomes to prevent this biochemical nest from absorbing energy, it is estimated that with only one ice worm, I really don't know how long it will take to complete this big project.

After thinking about it, Li Feng gritted his teeth fiercely in the end. He decided to take a risk.

The next moment, Li Feng was in the sky above Europa. Suddenly, he took out a blood crystal and threw it into the depths of the frozen lake.

The blood crystal fell into the frozen lake, and since it had no vital signs, it didn't attract any attention from the invisible monsters in the lake.

It just relied on its own weight and kept sinking.

"Boss, what are you doing?" Lin Yang and Polo for Li Feng's sudden move. I was very puzzled, but Li Feng didn't say much.

The only thing he needed to do next was to wait, after all, the frozen lake was actually just an outlet for the entire underground water ocean world of Europa, and the entire water ocean world was hundreds of miles deep.

I'm afraid this addictive process will really have to wait for a long time. Fortunately, the preparation of several people this time is sufficient, and several people can maintain it for three or two years by relying on the special nutrition pills made by the organization.

And so the days passed.

Li Feng and the others waited like this for more than a month, and finally on the forty-day day, the blood crystal finally sank to the bottom of the water and ocean world naturally.

Soon, the ice worm found the blood crystal in its mouth, returned to the back garden of the lizardman castle, and then planted it under Li Feng's instructions.

At this point, Li Feng breathed a sigh of relief.

After more than forty days of waiting, a total of hundreds of invisible monsters have hatched during this biochemical cultivation nest.

On average, about ten can hatch a day, but Li Feng also got a clue from it.

That is, these invisible monsters are hatched and fall into the sky, and they no longer stay in the castle, but all leave the castle and never come back.

It seems that the potential order they were created was to protect the whole of Europa?

However, these command mechanisms also made Li Feng take advantage of a loophole, since the castle was not guarded by any invisible monsters, it was more convenient for him to teleport the army.

Although Europa is extremely far away from the Earth, since the Blood Crystal can teleport even to different planes of the Earth and the Blood Moon World, there should be no problem with Europa, which also belongs to the solar system.

Sure enough, through the transmission, the next moment, a large number of king lice insects were teleported.

Li Feng also took advantage of the fact that before the next invisible monster hatched, he ordered the hundreds of kings and giant lice to burrow into the soil, and then began the destruction work.

Under the destruction of hundreds of king lice insect soldiers over two meters, soon the rhizomes under this biochemical nest were all cut off by the strong and powerful jaws of these insect soldiers.

When the last rhizome was cut, sure enough, the biochemical nest that had been growing and shrinking finally came to a standstill.

"It worked!" Li Feng wiped his sweat, it was really very risky, because the invisible monster on the next trip was almost hatched and landed.

If these monsters are allowed to hatch and land, only to find that their nests are being destroyed, God knows if they will provoke the invisible monsters of the entire water and ocean world to rush to the rescue.

But it's a pity that Li Feng finally destroyed all the rhizomes buried under the soil before the next batch of invisible monsters were born, so this batch of monsters that were about to be born lost their source of nutrients, and naturally they could not continue to hatch and grow.

"Well, cut off this source, and then you'll have to deal with these monsters that are still there."

Thinking of this, Li Feng had a headache, this biochemical nest didn't know how long it had survived, in this long time, God knows how many invisible monsters had been hatched, even if the source was solved now, it seemed that it would be a big trouble to deal with these existing invisible monsters.

Li Feng rubbed his temples, he really didn't expect that there would be so many obstacles if he wanted to implement his own planetary farm.

But fortunately, these invisible monsters only have two more difficult abilities to deal with, one is invisible, and the other is to ignore defenses to draw energy, and they themselves are very vulnerable.

In this case, Li Feng quickly found a way to deal with them, and to deal with these huge number of monsters, he only needed to use the existing large-area damage thermal weapons of the human race.

"Let's go back to Earth."

Li Feng didn't wait for the two of them to react, and as soon as his thoughts moved, the flying machine that had been floating in the air for a long time immediately turned into an afterimage and disappeared into the sky.

Within minutes, the craft was far from the frozen lake and had found a place to land on top of a high glacial peak.

"You two stay here to pick up, I'll return to Earth and I'll be right over."

Fearing that staying on the ground for too long would attract more and more invisible monsters, Li Feng hastily confessed, and immediately planted another blood crystal and disappeared into Europa.

Ten seconds later, when he walked out of the blood crystal space again and saw the familiar scenes around him, the whole person couldn't help but relax.

Yes, he finally returned to Earth, to the shelter.

Li Feng returned after a long absence, and immediately attracted all the core figures to come, and then inquired, it turned out that he had gone like this, but more than seven months had passed on earth.

My mother, when he heard that it had been more than half a year, Li Feng was stunned, he clearly remembered that when he arrived at Europa, he stayed for more than two months at most, not even three months.

In this case, the remaining four months are actually consumed on flying?

Due to the thirteen short-distance space jumps, Li Feng really didn't know that the space jumps that ended in an instant were actually four months later.

This also made him deeply feel that the unfathomable depth of this cosmic world, and now he is playing in the solar system, making more than a dozen short-distance space jumps, which feels like ten minutes, but it has been several months.

The lifespan of human beings is indeed too playful!

If the lifespan of human beings cannot be substantially improved, that is, even if you have the technological ability in the universe, you still don't have the capital to spend a long time on this.

This also created Li Feng's more intense pursuit of a longer lifespan.

At present, although the Blood Moon Demon Bead has been discovered, as long as he has the ability to advance in the cultivation of the Blood Moon, it is possible to live for hundreds of years, or even longer, but this small achievement, I am afraid it is still far from enough.

Li Feng cleaned up the emotion in his heart, and immediately summoned all the elders and relevant core high-level officials to come over and issue orders.

Soon, after his orders were issued, the entire Blood Shadow Organization was like a huge machine, and it was running one after another.

Taking advantage of the preparation period, Li Feng also returned to his family and had a small reunion for a few days.

Three days later, with the full preparation of the entire Blood Shadow Organization, the matter had been prepared.

Early in the morning of the fourth day, a low-level blood successor army composed of 10,000 people, as well as a large number of military materials and equipment, entered the blood crystal teleportation one after another.

On Europa's side, after the polo two were teleported back to Earth by Li Feng, the two of them did not dare to stay on the ground for long, and immediately raised the aircraft and floated in mid-air, waiting for Li Feng to return.

When the blood crystal space emitted bursts of red light, they quickly knew that the boss had finally rushed back, and looking at the intensity of the blood crystal red light flash, it was estimated that he had brought a lot of support. (To be continued......)
