At the end of the southeastern continent of Ordoja, at a depth of 3,000 meters, in the sea of Escalite.

The Vanguard, a prototype all-purpose cruiser belonging to the Willidis Army, sailed to the bottom of the ocean.

It is 200 meters long. Developed by the Terra Fidelista Air Force and destroyed before it was completed, the machine civilization was revived by the Willidis armies in the modern era.

As for the ships remaining from that time, they were old ships similar to those of the Ambar class, Diamante, and the medium-sized high-speed aircraft carrier named Aguamarina, and they were ships from the Terra Fidelia period.

What do you say?

Vanguard's captain is Ambra, the Ambal-type shipcore. Upon her confirmation, the operator looked back.

“No, the trees in this world are fossilized.”

It's the bottom of the ocean.

No magic power generation reaction. It is recognized that there is no recoverable value. "

"Well then, you don't need to stay long." We need to change course and return to our home port! "

Yoshihiro!

The all-purpose cruiser "Vanguard" has been at the end of the undersea world tree - a part of the main island of Apollo Floating Island that once sank.

I received an order from Jin Tokitomo to secure the world's trees. However, as expected from the beginning, the floating island and world tree that fell at the bottom of the ocean no longer fulfill their functions and are sleeping.

Speaking of the Willidis army, only the Vanguard can advance to this depth of 3,000 meters.

Previously, they were assigned to the 3rd Fleet Guard Corps, but in order to take advantage of their versatility, they were often given special tasks such as transporting special forces and exploring the seabed.

Captain, I feel something for Sonar.

Deep Sea Demon Beast?

The sea is called the open ocean, and there are monsters as huge as you can imagine on the ground. It can be Kraken or Cesar Pent, but it can be an unknown giant creature.

In fact, Vanguard also fought off sea creatures three times before reaching the world tree, which became a seafloor ruin.

No, it's an artificial sound source.... Seems to be heading towards the seabed ruins. That number, one. "

Submarine?

Submarines also exist in the Willidis army, but no submarine is exposed to this depth. If it wasn't a sea creature, it would be a submarine, like the Vanguard.

Who is it? The Great Empire… or the Stigmatized Empire? A force of our own that we don't know about.

Small objects are separated from moving objects!

Torpedo!?

Ambra was hit by an attack. The listening hand reports.

No, the shape is complicated. I don't know what it is, but it looks like they're coming for us. ”

Ambra analyzes the data of the enemies she leaves to the crew. Sound prints similar to those of the formerly operated Powered Suit "Undine".... the human type.

Rapid ascent! All ballast drains. Main tank blow!

"Vanguard" began to surge. I avoided fighting underwater and chose to retreat.



"Shit, I let him get away!"

In the cockpit of the demonic machine Iktuos, Louie, the twelve knights of the Stigme Empire, bit her teeth.

Iktuos was a mermaid-type ghost machine equipped with a mermaid-type underwater module in the upper body and a fish-type underwater module in the lower body. As it looks, it specializes in underwater combat and boasts the ability to navigate the deep sea.

"I can't believe there's a ship that goes down the bottom of the ocean like this..."

Louie glanced at an unidentified object that disappeared from her spotting gear.

"I don't want to think I'm a Groundman..." Very well, I will do as Director Hal commands. "

Fragments of a floating island sunk to the bottom of the sea - check the world tree, and if possible, acquire it. Among the Stigmatiz Empire, only Ichtios and a few submarines have chosen Louie for this mission.

Are the others doing well?

Louie is on her own.

Recently, I was summoned by the Secretary and reprimanded for the ground invasion, but it was only a good annoyance for Louie, who was not in the invasion team.

The incompetents who failed the operation were bad. I was angry whenever I remembered.



The Stigme Imperial Army moves to secure the world's trees.

The shapeshifter's intelligence department had grasped the movement, so it reached my ears.

Securing the world's trees, which continue to produce magical power, is nothing short of securing war resources for them. We must stop the enemy in order to prevent them from gaining strength.

"Well, I'm ready..."

Go to the Aries Floating Island Command and check with Diamante immediately.

What's the movement of the Stigme Empire?

"We are sending a fleet to conquer the land with the world's trees." Earlier, Vanguard reported that it was on its way to investigate the undersea remains of the Escalite Sea. The world's trees are fossilized and unavailable. "

If so, you can ignore it.

There were eight world trees in this world during the Apollo civilization. Broken World Tree Ruins - The broken world tree is dead because our "Nephritis" blew up during the Apollo Island invasion strategy.

If the remains of the seabed are also crushed, then there are only six left. And the vampires are trying to conquer it.

We can't afford to send a fleet to all of them, but we've taken measures.

We didn't leave the world tree alone either. The Empire was also targeting us, so we were preparing not to be used.

"Well then, let's get started." The essence of Project Sea Pang - Operation Return of Owners, activated. ”

Yes, my lord.

Diamante nodded.



That day, four of the world's trees scattered around the world disappeared.

In the east of the continent, in the west, underneath the southern desert, under the ice continent that was conquering and factoryizing the Great Empire.

A beautiful and giant world tree has disappeared. It's as if it didn't exist from the beginning.

At the same time, four world trees appeared on an artificial island on the southern side of the continent.

The name of the island that the world does not know is Sea Pang.
