One o'clock in the morning.

The night was quiet, it was a moonless night.

The night is like a black veil, covering the face of the earth during the day, and it falls into a lazy sleep.

The stars in the sky blinked with sleepy eyes.

People should have fallen asleep a long time ago, and it seemed that it should have been a calm and peaceful night.

However, in the context of the invasion of the Maltese and the almost complete loss of the earth, such a night cannot be peaceful for humans.

The area controlled by the First Army of the Earth Combat Knife is still brightly lit, the engine roars constantly, and it looks like it is extremely busy preparing for battle.

In the midst of all the noises, in some seemingly inconspicuous areas of various sizes on the outskirts of several cities, the rumbling roar of engines suddenly came from underground, and gradually increased.

A few minutes later, hundreds of twenty-story underground submarines emerged from the ground, quietly opening the huge side doors of the submarines under the cover of darkness, waiting to perform a new mission.

"Let's go!"

As Yang Yi gave the order to attack, the armored combat vehicles, heavy tanks, various mechas, intelligent author robots and other heavy troops of the assault brigades on the ground of the Earth War Knife all turned off the lights, and the engine engine was also turned on silent, and the concealment mode of anti-infrared scanning quietly drove towards the underground submarine area on the outskirts of the city.

After arriving at the underground submarine assembly area, without making any stops, he drove directly into the submarine cabin through the side door and began large-scale secret loading.

Half past one in the morning.

About 120,000 personnel, equipment, and combat materials of the assault brigades of the First Army of the Earth Combat Knife were all loaded.

As the underground submarine group loaded with men, equipment, and combat materials began to dive rapidly, and eventually disappeared into the night, the land where the underground submarine appeared seemed to be quiet again.

However, there are still a large number of audio and projection equipment that simulate the noise of troop activities in the original station of the Earth War Knife, simulating the illusion that the troops are still stationed in the same place and are preparing for war.

In the eyes of the uninformed, the 1st Army of the Underground Combat Knife was still stationed in place, without any signs of movement.

This was the part of the covert operation in Yang Yi's plan to raid the Maltese.

First, the army's huge underground submarine group was used to secretly transport ground troops underground to the vicinity of the Maltese assembly area, and then launched an attack to achieve the effect of a surprise attack.

Underground submarines dug rocks and excavated earth and holes in the ground hundreds of meters deep, opening up new shipping lanes and sailing quickly in the direction of the gathering of Maltese ground troops.

The night returned to its tranquility, and it seemed no different from peacetime. But in the middle of the night when the Maltese invaded the earth, behind all the tranquility, a greater storm was heralded.

At the same time as the ground forces were dispatched, most of the spacecraft of the Earth Combat Knife Air Assault Brigade were waiting nervously, except for a few spaceships that had been on alert patrol.

On the ground in the control area of the Earth Combat Knife, on the take-off and landing fields of the spacecraft temporarily opened, the pilots are already sitting in the cockpit fully armed, and all the spacecraft weapon systems are ready, ready to take off, and ready to take off and fight at any time.

The reason why the air assault brigade has not yet been fully dispatched is due to the relatively fast speed of the Bat-type spacecraft and the relative proximity to the assembly of Maltese troops.

In order to cover up the traces of the ground troops' dispatch and not to reveal the true intentions of the ground forces in advance, the combat meeting decided that the 4,100 Bat-type spacecraft belonging to the air assault brigade would be dispatched a little later than the ground troops, so as not to attract the attention of the Maltese and fail to achieve the purpose of the surprise attack.

Yang Yi sat in the command vehicle of the underground submarine group army, watching the enemy's movements on the holographic screen of the command system with full attention, and issued instructions to the assault brigades from time to time.

This raid was different from the last engagement in the mountains, this time the battlefield was in the city center, and it was a night operation, which was more demanding on the troops.

Underground submarines are sailing at high speed, and it will take about half an hour to enter the attack position.

In half an hour, there will be another bloody battle with the Maltese.

According to the battle plan, the air battle between the Bat-type spacecraft and the Maltese will start three minutes in advance to contain the Maltese's aerial firepower and attract their attention, and cover the ground troops from the underground submarine landing on the ground.

With the current number of the Earth Combat Knife Air Assault Brigade, it is fully capable of engaging in a head-to-head confrontation with the Pentagon Fei deployed nearby by the Maltese, which is why Yang Yi dared to dispatch ground troops to launch a surprise attack.

According to the ground information that has been mastered so far, the number of pentagonal spaceships that the Maltese have assembled is only half of the earth's combat knife, and as long as the open space suddenly strikes at the same time, no matter how fast the Maltese react, it is impossible to immediately organize a counterattack without knowing the details.

As long as the enemy is unable to organize an effective counterattack within an hour, the 120,000 troops of the Earth War Knife can suppress the Maltese ground forces and firmly grasp the initiative.

Minutes and seconds passed.

The hour hand points to 1:55 a.m.

The underground submarine forces have reached the designated landing sites and have begun to rapidly float to the surface, preparing to establish a landing field.

Over the city where the Maltese ground forces were assembled.

Suddenly, countless engines sprayed blue light, accompanied by a deafening roar of engines, and the Bat-type spaceship formation of the Earth War Knife Air Assault Brigade launched an attack on time.

As the Maltese pentagonal ship began to meet each other, one of the largest aerial battles with humans since the Maltese invasion broke out.

In a flash.

The night sky was full of roars and the roar of spaceship engines. Thousands of ships with blue tails maneuvered through the air at high speed, and the bright light of the blue energy pillars filled the night sky.

With 4,100 bat-type flying ships and nearly 2,000 pentagonal flying ships of the Maltese, the Earth Combat Knife Air Assault Brigade has an absolute superiority in numbers.

Apparently the Maltese did not anticipate a sudden move on the human side, and most of the Pentagon ships were not on alert, except for the hundreds of ships patrolling.

Just a few dozen seconds after the air battle began, hundreds of pentagonal spaceships were shot down in the encirclement and annihilation of the huge number of bat-type spacecraft of the air assault brigade, and the remaining pentagonal spacecraft rushed into battle, and in the chaos and the formation was disrupted, and the spacecraft were constantly hit by the engines and fell, or exploded in the air.

Obviously, the Maltese are not good at dealing with such attacks, although their pentagonal spacecraft technology is advanced enough, but now their advantage is not very obvious, in the face of attack power is not much different from theirs, the number of you go to your huge bat-type spaceship, the pentagonal spaceship is tired of coping.

In just half an hour of the battle, the loss of the Pentagon ships amounted to two hundred. Of course, the Earth Combat Knife Air Assault Brigade also paid the price, close to thirty ships were shot down.

Two o'clock in the morning.

"Comrades-in-arms, the ground assault begins, advance in depth!"

In the night, Yang Yi showed a firm gaze on his face, and a burst of blood-boiling killing intent surged into his heart, and he gave the order to attack the assault battalions that landed on the ground.

This is a battle of revenge, this night, the earth's war knife wants to fight its own military might, a snow earth repeatedly fought the shame.
