Chapter 149

Such a machine has quite high requirements in terms of weight and power, and the strength study of the huge sinkhole wall of Skull Island finally completed the design drawings. The final design is a building about five stories high, a 20-meter-high cuboid with a width of five meters by five meters. The structure is made of high-strength aluminum alloy, and the surface is also made of high-strength alloy steel as armor.

There is a backup diesel generator in this structure, and its energy is supplied externally - yes, in the vicinity of the big pit, a thermal power station was built to power this machine. It has a powerful light and is used to climb the walls of the cave by a set of locking mechanisms inside the structure, which are gradually lowered by holding sections of steel rails to the walls with thick and long high-strength nails, and the rails are also fed by a transport elevator from above.

And this mobile research station has a strong lighting - but generally does not turn on, but through the infrared lens to observe the outside, of course, there are enough instruments and equipment in the building to be able to sample and analyze, and on the outside of this research station there are weapons - 37 mm combined small anti-aircraft guns, placed in two groups.

Analysis of the existing creatures on Skull Island, including the oversized bone lizard, proves that these organisms can't stop the 37mm shells, and that they are still carbon-based. The cave has been detected with sonar and radar, and the deepest point may be more than 20 kilometers, and the station is expected to gradually descend to a negative altitude depth of about 10 kilometers in about two months, and then try to fix a platform, build a permanent research station, and then proceed to the next step of the expedition.

Sunlight does not reach the bottom of the sinkhole, and it doesn't seem like a good idea to turn on the headlights in a dark cavern - the station has a lowered visor and movable armor from the outside, just to prevent the light from the inside from radiating to the outside - in the middle of the station, there is indeed a large viewing window sealed with tempered glass.

When you go down to the sinkhole, at the first depth of about a kilometer, there are plants and various animals on the walls of this sinkhole - after all, this is not a vertical downward cave, and the machines inside the research station will trim the walls as much as possible when laying the tracks.

After only one kilometre down, the scientists have collected more than 100 never-before-seen specimens, ranging from plants to insects and even small animals. The station does not face the side of the cave wall, but has a gap of about two meters, and there are several platforms that can be used to collect specimens, and these platforms have separate doors from the interior - not all the creatures that live on the cave wall are safe and peaceful......

Beneath this hugely expanded "Earth" shell lies a massive cave system that spreads all over the world, and also has an ecosystem that is different from the surface of the earth. And Hong Long is now roaming in it - as a sea dragon, although he is not as agile on land as in the water, he has no problem moving.

The sea dragon does not necessarily need water, his carapace is very good at avoiding water loss, and the semi-energetic sea dragon is beyond ordinary creatures - this is known as the king of a continent, but anyone who stands at this height is almost very exaggerated in terms of vitality and adaptability.

For example, the Sea Demon Chapter that moved in the other direction - just looking at this guy's race and appearance, it definitely doesn't look like a creature that can survive on land for a long time. But in fact, this monster can actually survive on land - its skin looks sticky and seems to be full of moisture, but when you do touch it, it will find it very dry and rubber-like.

The sticky look is just an illusion. The Sea Demon also has an internal skeletal structure, at least its lower and upper jaws, and the roots of the tentacles that support it also have a structure that may be bones, and these tentacles are so powerful that they can support the monster's body to move freely on land.

And its movement is very weird, and the tentacles make this monster's movement completely inconsistent with the conventions of the direction of movement of ordinary animals, so whether it is attacking or escaping, the Sea Demon Chapter has a unique talent - but is there any creature that can make it escape in this world? I'm afraid it's only the sea dragon, right?

When this terrible creature moved, the tentacles still grabbed the protists that devoured this place from time to time, the intelligence of the Sea Demon Chapter is actually quite developed, but it is completely the wisdom of a beast or an extremely intelligent beast, there is no humanity at all, and naturally there are no concepts that can only exist in human society - abstract concepts such as justice and reputation.

The sea dragon has it, but this thing has long since lost its sight, and the last vestige of Hong Long's former human being is probably that he knows a lot of abstract concepts, but he has long since stopped following them. After all, matter determines consciousness, and under the influence of completely different bodies and hormones, it is tantamount to a fantasy to insist on the so-called human nature.

In the underworld, living things are different from the surface, and many animals are able to survive by eating inorganic matter and even absorbing organic matter like plants. There is also a water system underground, but the cold light of the zenith does not cause water circulation, only the water circulation caused by geothermal heat, so there is not much rain and few clouds.

There is a lot of water in this place, underground seas, underground rivers, underground lakes from fresh water to salt water, and even acidic and alkaline solution rivers, lakes and seas. Of course, the ecology is much stricter than the surface - at least there are not so many natural wonders to eat, but there are many wonders that can kill people in an instant.

The sea dragon swims on land, and there is a lot of water here, so he also goes to the shallow lake here from time to time to roll around, and of course there are eyeless creatures that will attack the sea dragon, and it is not small...... The freshwater was still very clear, but all of a sudden there was mud and sand and the water was like an explosion - it was the predatory carnivorous freshwater shells hunting underwater.

The freshwater shell, which was more than 300 meters in diameter and more than 40 meters in height, suddenly opened the shell with its strong adductor muscles, and this action caused the water to suck the prey into the shell with great suction force, and it also ejected the fleshy foot, which was covered with barbs, and the tongue of the shell, which was like a thick hollow spear, and the cavity more than two meters in diameter was filled with venom.

The sea dragon is the prey, and Hong Long was originally just rolling in the freshwater lake, but he didn't expect to be attacked......
