"What is this thing? It looks like it has a very low density, yet it can float on the blood pool." The hound's tone was full of confusion.

"Not sure... maybe it's some kind of associated crystal mineral?" Ke Lan certainly knew what this was. Leviathan's skeleton was made up of this kind of crystal... but he couldn't explain it to Hound and the others.

"Associated ore? How could this thing appear here? Isn't there no mineral vein under Manstein's base?"

"Down below the base..." Ke Lan seemed to have thought of something and suddenly shuddered, "By the way, Hound, have you found a usable computer in the main control building? It would be best if it can be connected to the base database."

"The one in Manstein's secretary's office will work, but you can't access the LAN database. The network server of the entire base has been blown up. If you want to look up information, you can only find local files on that computer." The Hound shrugged.

"Local files... maybe there's something I want in the secretary's computer! Old Dog, please help me watch this place, I'll be back soon!" After saying that, Ke Lan quickly ran towards the main control building.

…

In the office, in addition to Manstein and his female secretary, there were four new faces - they were all survivors rescued by Ivan from the ruins. The injuries of three of them were relatively minor and had been treated, while the condition of the last person was rather bad: both of his thighs were cut off, the tissues at the wound had already died, and the massive blood loss had caused him to fall into a coma. Ivan was sitting on the ground in a somewhat dejected manner, his hands and clothes were covered with bright red bloodstains.

Seeing Ke Lan rushing in, everyone in the room focused their eyes on him. Ivan raised his head and looked at him, then shook his head slowly: "I tried my best. The operation was successful and the bleeding stopped... But before we found him, he had already lost too much blood. Without spare plasma, I couldn't save him."

Perhaps because there were too many "insiders" gathered there, the base's medical room was one of the most thoroughly destroyed buildings. Ivan even used the instruments he carried with him for the operation, and it was already very difficult to stop the bleeding.

"I have asked everyone about their blood types. Unfortunately, the injured person was the only one with type A blood. I tried to give him a small amount of type O whole blood, but he had a severe hemolytic reaction... Plus, there is no suitable liquid here to serve as a blood substitute... He can only hold on for half an hour at most."

"All we can say is that everyone has his own destiny." Ke Lan sighed, nodded to Ivan, then turned to look at Manstein.

Manstein was shocked by Ke Lan's look and came up to him in a flattering manner: "Excuse me, Mr. Ke Lan, what can I do for you?"

"Is there any construction record of this base in your secretary's computer?" Ke Lan asked.

"The construction records... should be there, but which part do you want?"

"I want photos and videos of the part about excavating the rock and pouring the foundation. It would be best if we could see Leviathan's spine under the rock." Ke Lan pushed the keyboard in front of Manstein.

"Okay, I'll help you find it right away." Manstein took a deep breath and began typing quickly on the keyboard.

Soon, those photos appeared on the screen. These were all photos taken at the beginning of the construction of the base - the heavy large equipment was disassembled into boxes of parts, which were transported directly to the sky above the construction site by airships, and then the containers were lowered with steel cables.

The workers waiting below assembled these parts, and one construction machine after another soon appeared on the construction site.

Ke Lan kept clicking the mouse, flipping through the photos one by one. It was not until the 31st photo that he finally saw the scene beneath the rock layer.

The laser drilling machine cut eight 20-meter-square deep wells on the rock layer, reaching the main body of Leviathan. Workers wearing engineering power armor will drive the pre-made alloy frame into the deep well. The next step is to pour high-strength concrete into the alloy frame and cast the foundation piles.

With the help of the strong light of the searchlight, you can vaguely see a white object that looks like a skeleton at the bottom of the deep well.

"This is the spine of Leviathan." Manstein said, pointing at it.

"Are you sure this is Leviathan's spine? And not something else?" Ke Lan asked.

"Sure! Leviathan's spine is only covered with a layer of skin tissue several meters thick, with almost no subcutaneous tissue and muscles. There is no chitinous shell on the skin surface like the Thunder Beast. It only takes a few days for a high-power laser to cut through this layer of skin, and then drive the foundation piles directly into the Leviathan's spine." Manstein replied. Although he did not participate in the construction of this base, if he wanted to become the highest person in charge of this base, he must do this homework.

"This...this is a bone..." Ke Lan said to herself in some confusion.

"Yes, it's bones. Leviathan is the same as all carbon-based creatures. Its spine is naturally made of bones." Manstein said on the side, "But its bones are really hard. Otherwise, the foundation could be dug deeper."

Ke Lan subconsciously clenched the mouse... But what he saw in the video... Leviathan's skeleton was clearly that kind of inky black crystal...

Apart from the chitinous exoskeletons of crustaceans, the skeletons of most carbon-based organisms are mainly composed of calcium and phosphorus. The skeletons of the native creatures of Alpha Star also contain some metal elements to increase strength. Such skeletons may be able to support a body several dozen meters tall, but for a behemoth like Leviathan, they are still too fragile...

This white bone surface is definitely not Leviathan's spine, at least, not its true appearance.

There is a huge difference between this Leviathan and the one Ke Lan saw in the video.

But... the inky black crystals appeared in the blood pool again, and inside the crystals there was the same dark red substance...

This is definitely not a coincidence.

There was only one Leviathan from beginning to end.

According to the information provided by that video, Leviathan was obviously killed by the Alpha civilization, but the insects that killed Leviathan attached themselves to Leviathan's skeleton, which made Ke Lan a little confused... Could it be that the Alpha civilization intended to use the skeleton of the previous generation of Leviathan to create a "new" prehistoric beast?

So... the Leviathan under their feet now is the one created by the Alpha civilization?

Considering the size of Leviathan, the amount of material needed to "revive" it is an extremely terrifying number. When the Alpha civilization killed it, the death ray cannon annihilated more than half of the flesh and blood of Leviathan - that is to say, even if they put all the remaining flesh and blood together, it would be difficult to piece together a complete Leviathan...

However, after so many years, Leviathan's "completion" has still not reached 100%. Even its blood vessels are still empty, let alone allowing this prehistoric beast to fly into the sky again.

The current Leviathan is just a "semi-finished product".

If this guess is correct, then the previous questions can be easily explained - the monsters' seemingly strange behavior is actually collecting nutrients for Leviathan's "rebirth", and the giant cocoon in the square is actually a very special "digestive organ".
