"Your Majesty, I may have guessed the meaning of the last sentence left by Lord Qinglong Beast." It had been a few days since the door of the human world had been opened, and the secrets of the digital world had been known about the Four Holy Beasts, and the Molecular Beasts reported to Caesar.

Caesar had guessed a lot of things through his conversations with the fairy beasts, but the last unfinished sentence left before the green dragon beast disappeared, 'Go to the source of all things, follow the instructions of the badge...' was a bit confusing.

"When Lord Qingdyumon speaks of the source of all things, he should refer to the abyss of the deep sea, and the guidance of the badge should refer to the sacred plan and evolution key of the children who have been chosen..."The molecular beast said.

There is a saying in human society that man evolved from monkeys, and before the evolution of monkeys, all species were born from the sea, from the deep sea where there was no light, and evolved step by step.

It can be said that the deep sea is the most suitable for the title of 'source of all things', and according to the molecular beasts querying a large number of scattered ancient materials, it is found that there is a similar statement in the digital world.

Each of the selected children wears a necklace-like evolution key with a badge representing their own spirit, and the Blue Dragon Beast should refer to the children's badge.

Hearing the analysis of the molecular beast, Caesar felt that it should be eight or nine and ten.

Caesar guessed that the badge might be the badge of the children who were chosen, but the source of all things really didn't think about it in the direction of the ocean.

After all, the theory of biological evolution or something is studied by human scientists, and Caesar didn't think about it at all, so to speak, it was dark under the light.

"Among the Four Heavenly Kings of Darkness, there is a Dark Heavenly King who is in charge of the ocean, and the Deep Sea Abyss is his base camp." The molecule beast said, sending the dark king's information to Caesar.

Caesar opened the information, and the model of the Four Heavenly Kings of Darkness appeared in the air.

It was a large dragon, snake-like in length, with swimming fins on either side of its abdomen, and a metal body in golden steel armor, covered in alloy.

At the tip of the head, there is a huge cannon muzzle, the top of the head also has a sharp blade like a single horn, the back of the head has black hair, and the tail is forked into two tails, and the overall look is full of power and deterrence.

Steel Drakemon, Ultimate Body, Modified Digimon, Evil Sea King, Overlord of the Sea, covered in the strongest alloy, the final form of the Sea Dragonmon species, not only can rebound all attacks with this metal body, but also has the fastest movement speed among aquatic Digimon, and has undefeated combat power on land.

Special move, the 'Ultimate Wave Cannon' that fires an energy cannon from the front of the nose to attack the enemy.

"......" Caesar looked at the Iron Drakemon's profile, his brow furrowed, and his fingers tapped down on his desk.

When the tribe was born, it had trade with the forces of the sea and knew the sea very well.

The sea of the digital world is divided into several levels depending on the depth, including the shallow sea with plenty of light, the deep sea with thin light, and the dark sea with no light at all, or the black sea for short.

Finally, legend has it that at the bottom of the ocean, there is an area that is deeper and darker than the Black Sea, and the huge water pressure keeps countless Digimon out, and even the native pure aquatic Digimon are difficult to approach, and it is called the 'Forbidden Sea'.

The Steel Sea Dragon Beast lives in the Forbidden Sea area, and according to the analysis of the Molecular Beast, the source of all things that the Green Dragon Beast said is likely to be in the Forbidden Sea.

It was the territory of the Steel Sea Dragon Beast, one of the Four Heavenly Kings of Darkness, and the environment was special, so it was necessary to think long-term, and not act arbitrarily because of random guesses.

"Gather information about the forces of the Steel Sea Dragonmon, I remember that the Vampire Beast seems to have emblem copying technology..."Caesar thought and spoke.

When the Molecular Beast heard this, it immediately began to search for it, calling up the technology of the Vampire Demon Beast to copy the badge back then.

This matter involves the Steel Sea Dragonmon, and the stakes are very high, and it must be investigated.

The chosen children and their badges are very important, and they are the key to dealing with the Four Heavenly Kings of Darkness, and even against the terrifying existence, which can be seen from the fact that the Four Heavenly Kings of Darkness have worked so hard to blockade the human world.

Although, at present, Caesar only knows that the children who have been chosen have the power to make their companion Digimon evolve quickly, and they have not yet discovered anything special.

However, as the backhand of the Four Holy Beasts, the power contained in the selected children is definitely not that simple, and it has not yet been shown.

Caesar couldn't let the chosen children take the risk of going to the Forbidden Sea to verify that the place where the Blue Dragon Beast said was not like that.

Nor can you risk losing your badge, this subordinate dives into the Forbidden Sea, and if you want to enter the Forbidden Sea, you must pass through various areas of the Diving Sea, the Deep Sea and the Black Sea, which is very risky.

Because of the particularity of the sea, the tribe's base is in the sea of steel sea dragon beasts, and the number is the smallest, and the hand only extends to the deep sea area, and the black sea has not been touched, let alone the forbidden sea.

Faced with this situation, Caesar sounded the technique that the vampire monster had mastered, copying the evolution key and emblem.

Back then, when the vampire monster entered the human world to find the eighth chosen child, it relied on the copied evolution key and badge to search everywhere.

The Molecular Beast quickly found the technology and put it to use, replicating the badges of the eight chosen children.

Caesar recruited some agents from the tribe and the monsters, gave them the replica badges, and asked them to cross the Black Sea and dive into the Forbidden Sea to investigate the situation.

At the beginning, it was not going well, the dark and lightless environment in the Black Sea had a great impact, and when entering the forbidden sea area, the terrifying water pressure exceeded everyone's imagination, and there were several tribal warriors, because they had been in the forbidden sea for too long, and they died under the water pressure.

However, Caesar soon found a way to deal with it, and there is a special thing in the world of pirates that deals with strong water pressure, and that is the bubbles of the Chambord Islands.

The Chambord Islands are unique in that they are small islands made up of the roots of the largest mangrove tree in the pirate world, exposed to the sea, and the strange resin secreted by this mangrove tree expands to form bubbles due to the air.

This peculiar bubble is the key to getting to Fish-Man Island, and the Chambord Islands have a special coating craftsman to coat the pirate ship, so that the pirate ship can dive underwater and reach the Fish-Man Island at a depth of 10,000 meters.

No matter how strong the water pressure is, these special bubbles will not crack the membrane, and the people inside the bubbles will not be affected.

After Caesar introduced these bubbles from the pirate world, the agents who infiltrated the Forbidden Sea were no longer affected by the water pressure.
