The former capital of the Kingdom of Longthog is now called Poseidon. The south and west of the city are plains, the north is mountainous, and the east is the seaside.

Poseidon is now on level one alert, and the entire city is under level one martial law. The once prosperous city is now in a state of death.

There are patrol troops patrolling the city, and checkpoints have been set up in many areas. All people entering and leaving are subject to questioning and inspection.

Because in the city of Poseidon, many important figures have been assassinated in recent days, including some police officers and officers from the police force or the army.

Frano Serac knew at this moment that the enemy had infiltrated, but no one knew where they were hiding, so he could only conduct a carpet search.

Frano Serac knew that the enemy was playing psychological tactics on him to keep him in a passive position. The Great Sword and Shield troops had now surrounded him from the north, southwest and south, and the eastern seashore seemed to be the safest at the moment.

The enemy is now advancing step by step both openly and covertly.

Frano Serac really wanted to ask for help, but at this moment the more important places on Mars were being protected by the Dion Army with all its might.

The city of Poseidon is dispensable to the current situation of the Dion Empire. The current defenders of Poseidon city include the local army and the defeated Dion army.

The morale of the entire city's army is now very low, and Frano Serac has no way to solve the current problem.

If he chose to surrender, he didn't know whether the Skywing Mercenary Group would make things difficult for him, but he knew for sure that the people of the former Longsog Kingdom would never let him, a traitor, go, and the angry people would definitely cut him into pieces.

The only way for Frano to temporarily relieve his inner fear at this moment is to rely on alcohol and women to temporarily numb his inner fear.

…

On the other side, the Great Sword and Shield troops surrounded the city of Poseidon from the north, southwest and south, but in fact there were also troops deployed in the east.

The Great Sword and Shield Forces received the new amphibious Ms and mobile fortress developed by the Skywing Mercenaries.

In addition, the Cross Vanguard also deployed F90M (Marine Type) underwater combat equipment to conduct deep-sea exploration, and the deep-sea camera on the left shoulder was observing the movements in the sea.

Many F90M drivers were very surprised. They did not expect that the terraforming of Mars was not just about the land on the surface, but also that there were abundant fish species and various marine plants in the deep sea.

The pilot almost had the illusion that he was in the deep sea of ​​the earth.

The F90M is covered with a translucent cloak that has the ability to change color. The color can change into the color of local marine plants or sand flows, and it can even be immune to sonar detectors.

…

Outside the city of Poseidon, there are troops defending in the north, southwest and north directions, forming a standoff with the Great Sword and Shield troops.

Both sides have now formed their battle formations and are ready to fight at any time.

Inside the city of Poseidon, members of the Great Sword and Shield Force who had infiltrated had already placed bombs at different locations.

The anti-Dionlonsog forces that acted with them were hiding in every location in the city.

The local anti-Dionlonsog forces, informants and undercover agents are waiting for news.

They waited until night and sneaked into the city of Poseidon with the Great Sword and Shield Force code-named the "Mountain Rat" Force.

Every team leader of every Mountain Rat Squad took out the controller and pressed the button.

Explosions occurred in succession at every location in the city of Poseidon.

Immediately put the local garrison, which is on level one alert, on high alert and take corresponding actions immediately.

The Anti-Dionlonsog Army began to move, launching surprise attacks on many checkpoints.

The incessant sound of gunfire made many local residents hiding at home dare not look out the window. Some brave ones secretly lay on the wall and watched the shooting outside the window next to them.

After the opening, the anti-Dionlonsog army used their broadcasting device to announce that they would sanction Frano Serac, make the traitor pay the price, and avenge the heroes who died because of him.

In the police department, civil war broke out in many branches. There were undercover agents who were against the Dionlonsog Army in the branches. After the explosion, many undercover agents followed suit and launched attacks.

The primary target of the attack was the Dionne police officers within the bureau.

Some undercover agents even occupied some police stations and called on other compatriots to rise up.

No matter whether they were determined or wavering, the people of the former Longsog Kingdom now understood that the fall of Poseidon City to the Skywing Mercenaries would probably take place in a day or two, so they immediately took action with these undercover agents.

In order to avoid being mistakenly shot by the anti-Dion Lonsorg army, these policemen held a red cloth on their chests to show that they stood with the anti-Dion Lonsorg army.

The same incident occurred within the garrison as within the police department.

The Mountain Rat Troops also began to move.

After learning that a surprise attack had taken place in the city, Frano immediately took command of the operations at his headquarters (located at the former Royal Palace of Longsog).

The marine forces in the east began to move, and countless Ms and mobile fortresses began to suppress the situation.

The city of Poseidon also dispatched a type of Ms that can be used both on the water and on the seabed, named "Flying Fish", which has excellent sailing speed on the sea surface and on the seabed. It can sail on the ground by relying on the air cushion of its legs, and has a good speed when sailing on the ground.

After receiving word that several police stations had been seized, Flano ordered the ocean surface warships to launch short-range missiles.

When the warship received the order and learned the launch location, it was preparing to launch the missile.

Many surface warships were attacked from the bottom by anti-ship torpedoes.

The sudden attack made the surface warship forces clearly aware that there were enemy forces in the ocean.

Order Ms. Flying Fish to go out and destroy the enemy.

F90M discovered the flying fish Ms, which looks like a fish and has the same limbs as Ms., but when it sails on the seabed, its hands and legs are upright.

The Flying Fish has an underwater range of over 35 knots.

The F90M launches amphibious rockets from its left and right arms. The amphibious rockets have a speed of over 60 knots in the sea and have tracking capabilities.

The Flying Fish is still a machine from more than ten years ago. After the Dion Empire unified the Martian sphere, it no longer developed amphibious Ms, and the Flying Fish was also not upgraded or improved.

The flying fish can dodge amphibious rockets, which have a tracking function and can turn and chase.

And while they were dodging, the F90M's six-row small torpedo launchers also fired at them.

The F90M even uses a backpack-mounted large water jet engine to reach a speed of over 70 knots, directly pulling out a thermal dagger and piercing the Exocet cockpit with one stroke.

In addition to attacking Exocet and surface warships, the F90M also focuses on attacking enemy submarines, and many large anti-ship torpedoes are designed to attack submarines.

Some submarines also launched torpedoes to attack the F90M.

The F90M's small torpedo launcher can switch the small torpedo function to an anti-torpedo function, shooting down torpedoes fired by submarines.

Another part of the F90M entered the underwater gate opened for them by the undercover agent and entered the enemy's underground hangar. Some small unmanned submarines (controlled by Haro) carrying other equipment of the F90 followed the F90M.

The Tianyi Mercenary Group's newly developed amphibious Ms and mobile fortress also began to take action.
