The battle between the Sea Dragon and the Sea Demon Chapter is almost "eternal", and it won't be long before these two guys will fight, and every battle will almost cause large-scale destruction of the sea or the collapse of the continent - but the land and the ocean in this world are growing and regenerating all the time, so when they start fighting again, the last destruction has almost been restored, and even the ecology will be restored or even better than in the past- After all, in every battle, these two monster kings will bleed and be injured, and the blood they shed is probably the nutrients for the explosive evolution of the ecology.

In short, the continent where these two monsters fought is getting bigger and more colorful, and the creatures and ecology on it are getting stronger and stronger, but every time the sea dragon and the sea demon chapter fight, these monsters still run away desperately, hiding and trying to find a way to survive in the aftermath of the battle.

Especially to avoid the Sea Demon - this king of the sea monster will constantly catch the creatures around him to eat to replenish his stamina during the battle, and it can eat with its tentacles anyway, so it doesn't hinder its fighting. The sea dragon is fierce and powerful, and rarely distracted to eat during battle, and Hong Long, with his terrifying strength, usually always outperforms the sea demon in the end, forcing the opponent to retreat and flee.

Since the world has changed, Hong Long's thinking has become even more strange, as a human part is already very thin, and now it is simply a heterogeneous thinking - this just proves that matter is first and consciousness is second, and what kind of existence you are depends on your body and species.

And the Sea Demon Chapter became extremely large at the beginning, almost able to occupy a piece of land the size of the Australian continent, but it was almost killed by the sea dragon in the battle, and the result is that it has been shrinking over the years, compressing itself again and again, and the final result is that it has become similar to the past, the body is about a ball with a diameter of more than twenty meters, and the length of the tentacle is more than one hundred and fifty meters.

No matter how big it is, it will be unilaterally crushed by the sea dragon...... For Hong Long, the threat of the huge Sea Demon Chapter will quickly decrease, and finally turn himself into a piece of meat, but for Hong Long's semi-elemental body, the giant Sea Demon Chapter is really nothing.

Only the Sea Demon of this size has achieved the best balance in defense, speed, and attack, enough to fight the sea dragon - although it is not semi-elemental, it has reached an extremely high level in terms of muscle strength, epidermal toughness, and hard and sharp teeth. And this time, the Sea Dragon and the Sea Demon Chapter once again smashed the continent apart, and the creatures on the land were killed and injured countless times, and these two monsters also discovered a huge underground cavity.

It was a whole new ecosystem—the light was provided by the glowing algae and plants on the huge dome, which were as bright as sunlight, and the plants would periodically turn off their light sources, creating an underground day-night cycle. There is still an alternation of land and water, with the dome at a height of hundreds of kilometers, and the inland lake and land below, where the transpiring water nourishes algae and plants in the sky, and after absorbing the heat brought by the geothermal heat, this water condenses into rain under the cold light, forming a complete water cycle.

As long as there is water, it is a viable environment for both the sea dragon and the sea demon chapter, and these two monsters naturally mark the way out - and only such powerful monsters can enter and exit. It's just that these two monsters also came down from different directions - the cave that came out at the beginning was too big, and there were many passages.

This is a huge underground cave system spread throughout the world, spanning hundreds of kilometers or even tens of kilometers in height, connected to each other by intricate passages, the ecosystem is not worse than the surface of the earth, and even more powerful creatures exist at the top of the food chain here.

In the place where humans live, Skull Island is just an entrance to the underground cavern system, and there is not only one such entrance and exit to Skull Island, but most of these entrances and exits are inaccessible, or there is no entrance as big as Skull Island.

Skull Island has long since become a testing ground for the major powers, and the storms and waves and reefs on the periphery are not insurmountable moats as long as you are serious - submarines can ignore storms, and explosives are enough to blow up the reef very easily to clear the way. Powerful nations have set up bases on Skull Island, and the reinforced concrete bases are equipped with weapons that are enough to deflate the monsters of those islands.

It is a treasure trove of biology and biochemical science, and the strange creatures that have disappeared from the continent due to ecological changes can still be found here, although the ecology is completely different. The creatures here are too terrifying for those who have just landed, but in the face of a prepared army, this is just meat.

Those creatures under the armor-piercing bullet could not be stopped at all, even the most terrifying kind of lizards that only had forelimbs, like skeletons, even if a giant lizard more than thirty meters above appeared, it was beaten into a puddle of rotten meat in just a few minutes with the cooperation of aircraft and artillery. However, the giant tiger and King Kong in the original report were never found.

The bottomless hole near the central part of the island is still a problem for all countries - a huge crater with a diameter of more than three kilometers, which according to sonar and radar shows that it is hundreds of kilometers deep, and there are even huge cavities underground. It's scary.

Such creatures would come from the ground, and the vanished King Kong and the legendary giant tiger might have come down from here, and it is even possible that the hollow below is where these huge creatures actually live and breed compared to the land. Even if it's a precautionary measure, people have to go down and take a look.

Since the cavern is large enough, it is possible to go down with some specially designed giant machines. If there are still those hoverships in the old world, it is a very good prop - but the hoverships that remain until now are all the meat of the hearts of all countries, and it is completely impossible to take them out for exploration unless the technology is re-analyzed and re-manufactured.

Then I am afraid that some kind of crawling machine will have to be designed - the theoretical design is some kind of machine that can lay its own tracks, can drive fixed tracks into the walls of the cave on its own, and then staggered them - lay the top one to the bottom, and repeat it again after going down, and such a machine is not only large, but also needs to have enough defense and firepower to carry a large number of soldiers and scientists to go on expeditions......
