The hollow earth of the legendary monster universe originated from the "Hollow Earth theory".

Originally proposed by Edmond Halley, a British astronomer who famously discovered Halley's comet, in 1692, a theory (hypothesis) that believed that the earth was a hollow planet. The theory also believed that the earth had an inner surface suitable for human habitation. Although literary works on earth center adventures made this theory popular for a period of history. But today this idea has received little support, and most scientists agree that the earth is a solid celestial body and believe that the earth hollow theory is pseudoscience.

In "Kong: Skull Island", Houston Brooks proposed the theory of earth's hollowness, which was also confirmed in Skull Island's geological survey. In "Godzilla 2: King of Monsters", 17 Titan monsters suddenly appeared, shocking all the people on earth, and cruelly proved the existence of the hollow earth.

As the center of the earth is assembled by pieces of "breaking pumice stones" that look plain, the twisted gravitational curve of the center of the earth magnificently rushed out of the surface like a volcano erupting. The earth-center creatures that were swept into the gravitational vortex were also ejected!

The black and earth-center monster legion was so creepy that people watched it.

The little black bird's Sai Xing Chao's brain immediately determined the source of these earth-center monsters.

Warbat: A huge aerial creature with a body of 130 meters long, with red membrane-shaped wings and a torso similar to a python. Its jaw has two fangs over 4 meters long, with amazing bite force and can entangle and suffocate the enemy. The Snake shows powerful flying ability and tangle attack in the fight of King Kong, and is said to include unshowed venom jet ability.

Hellhawk: has the head of an owl, bird-like feet and claws, and bat-like wings. It has a wingspan of up to 6.8 meters and has a very fast flight speed. Hellhawk is depicted as an aggressive carnivore, mainly relying on its beak and claws to attack, and can emit high-frequency sound waves to interfere with the enemy.

Rock Critter: This creature is 15 meters tall and has a stone shell like a hermit crab and multiple claws. Rock Critter is good at camouflage and ambush, and can drill holes at high speeds and generate earthquakes. They also have faster movement speeds on the ground, and claws can retract into the shell, making it look like a rock for camouflage.

Moreover, Wu Chen has noticed that these so-called center monsters are not natural evolution, but artificial semi-mechanical monsters. A complete mechanical life maintenance system that can survive in a vacuum, including respirators, and most importantly, mechanical bodies for combat: toxin teeth, alloy claws, power clamps, and various ammunition systems installed on giant bodies...

The striking sign on the sturdy semi-enclosed semi-open exoskeleton armor was also instantly captured by Wu Chen's eyes of true vision, which flashed and destroyed.

APEX spike neural machinery.

"So, these semi-mechanical transformation monsters all come from the center headquarters of APEX Spike Nerve Machinery." Wu Chen had already thought of it.

"Yes, Dust. We also intercepted a special signal source." The castle queen "Raging Ji" Ferosa, who closely monitored the evolution of the plot, amplified the signal source: "It is believed that it is the B.T.P.S. Biomechanical Telepathic Piloting System developed by APEX Spike Neural Machinery specifically for Mechanical Godzilla."

"Since we can easily intercept, it must not be a ghost quantum transmission." Wu Chen smiled and said, "So using 'telomatic' is not accurate. It still belongs to the category of 'wireless transmission'."

"Yes, Master. It is the wireless transmission of 'quantum encryption'." Queen of the Castle "Raging Girl" Ferosa completely agreed.

"This level of 'system' is simply an 'open source system' for us." Wu Chen boosted morale.

Open Source is full name "Open source code", and it is also a software release model called source code disclosure. It usually refers to a collection of a series of software that is publicly available and can be freely used, copied, modified and re-released. Generally, software can only obtain compiled binary executable files, and usually only the software author or copyright owner owns the original code of the program.

Using it by Wu Chen here actually means that the B.T.P.S. biomechanical telepathic driving system developed by APEX Spike Neural Machinery specifically for Mechanical Godzilla is too low. Compared with Wu Chen's "super brain area chain" with two digit queens of the same degree, it is equivalent to a fully open and unpreventable open source system.

The little black bird did not disappoint. The gods invaded the B.T.P.S. biomechanical telepathic driving system without realizing it.

Continuous transmission between the mechanical geocentric monsters, the core operator of the entire system was quickly found.

A semi-mechanical snake queen hiding deep in the flock of animals, and a human driver hiding in the armored pod on the queen's neck, or a "Central Rider" or a "Central Herder".

The simple version of the "Broken Database" that comes with the multi-function watch immediately locks the target:

Maya Simmons, an APEX executive and daughter of Walter Simmons, the company's president. In the original plot of "Godzilla vs. King Kong", the Imperial Organization and APEX opened a new path to the earth's center through King Kong and discovered a new energy source during the detection. Maya Simmons was ordered by his father to find energy in the earth's center. During the filming of the film, Godzilla discovered King Kong's traces and used atomic breath to directly create a path, forcing King Kong to fight him. In the conflict between the two sides, Maya ordered an indiscriminate attack to escape, but it angered King Kong and was crushed by King Kong with one hand together.

Obviously, the personal plot of APEX executive Maya Simmons has undergone a qualitative change due to player intervention. Not only was it not killed by King Kong, but it also successfully gained a foothold in the Earth-center world and moved APEX headquarters to the Earth-center world, developing a fusion technology that uses the Earth-center Titan monsters combined with human technology to create semi-mechanical war beasts.

"Chen, you guessed it right again." The castle queen "Raging Girl" Ferosa immediately contacted the plot: "APEX spike nerve machinery really established a base in the center of the earth."

"It's not just the base, Ferosa." Wu Chen insisted on his previous judgment: "Since the main field of the No. 5 competitive position is the super-time and space fortress of the Imperial Organization, then this geocentric world belonging to the affiliated field must be dominated by APEX spike neural machinery. So it is highly likely that it is the headquarters of APEX."

"Yes, that's it." Ferrosa, the Queen of the Castle, agreed immediately.

Just as Wu Chen confirmed that the "Geocentric Herder" was Maya Simmons, an APEX executive, the super-time and space fortress of the Imperial Organization, who felt the invasion crisis of geocentric forces, also activated the defense system.

Accompanied by a harsh alarm, the alloy gate of the Skull Island Outpost No. 33 was slowly opened.

A group of bloodthirsty beasts ran out wildly.

It is the native monster Death Jackal of Skull Island, a vibrant predator on the island. The Knife Jackal has leopard-like agility and great white shark-like biting force, and its spine is full of fiber thorns. Its atypical milky white blood is rich in calcium deposits. Its cruel nature is to any creature, not only attacking humans, but even eating each other when there is no food.

Similar to the semi-mechanical earth-center monster. The Knife-Red Jackal is also wearing a semi-open alloy exoskeleton and is equipped with many high-tech war equipment, including fire-controlled radar, communication base station, laser sight, Gatling machine gun, recoil-free cannon and honeycomb rockets.

The head of the head is far larger than that of the same type, and a single cockpit is also installed on the back of the Knife-Ringer Jackal King.

The true identity of the female knight who controls the Knight King of the Knights with the bioacoustic device of the Titan Behemoth invented by Dr. Emma Williams in the single cockpit was also analyzed immediately by the simple version of the "Broken Database" equipped with the multi-function watch.
