Elsewhere, at the border between Colony No. 2 and Colony No. 3, a battle took place between the Skywing Mercenary Corps' army-level fleet and Dion's army-level fleet.

From Letty, we learned that Dion's 3rd Expeditionary Force and Christopher's personal guards had already sneaked into the 3rd colony area.

But he himself didn't know the exact location of the eldest prince.

The 21st branch base of the Tianyi Mercenary Group is also investigating.

There will be a battle here, mainly because of the intelligence of the Tianyi Mercenary Group (mainly from the 21st Base). Some camouflaged detectors placed here discovered that there were abnormalities here (this incident happened earlier than the attack on the Heimla asteroid).

Afterwards, a reconnaissance team was sent to hide in a meteorite area and conduct camouflaged reconnaissance.

In addition, some optical camouflage (camouflaged wreckage) detectors were placed in another wreckage area for long-range detection.

They also placed disguised meteorites (probes, radars, etc.) in certain places for long-range searches.

Sure enough, it was discovered that huge amounts of pheromones were occasionally flowing in and out of the border between Colony No. 2 and Colony No. 3.

The Tianyi Mercenary Group used anti-optical camouflage devices and phantom particle devices to conduct a series of investigations and discovered that the Dion Expeditionary Force used optical camouflage to achieve stealth.

The Tianyi Mercenary Group then began a series of long-distance tracking and exploration, thus beginning to grasp their whereabouts and the time they entered and exited Colony No. 2.

The information learned from Lettice basically confirmed that Christopher was hiding in the No. 3 colony area.

The Tianyi Mercenary Group began to make a series of preparations.

First of all, before the attack on Marklena, the Skywing Mercenary Group arranged the Allied Forces to mainly consist of Earth Sphere troops, causing several brigade-level fleets under the Dion Expeditionary Force to be ambushed and suffer a severe defeat.

The three defeated brigade-level fleets attempted to escape into the No. 3 Colony area but were ambushed by the Tianyi Mercenary Group's ambush forces.

Then, the 4th Army Fleet of the Dion Expeditionary Force was dispatched to Colony Area No. 2 and into the country of Markrena to rescue their colleagues.

As a result, before Dion's 4th Army Fleet entered the No. 2 Colony Area, the Skywing Mercenary Corps' Army Fleet disguised as meteorites in the meteorite area ambushed Dion's 4th Army Fleet.

Brigadier General Shan Wenwu served as the commander of the army-level fleet of the Tianyi Mercenary Group's expedition against the Dion Army's 3rd Army.

16 shield-breaking destroyers launched electromagnetic accelerator cannons and wave after wave of mobile drill missiles and Minov particle missiles.

Half of the targets of the electromagnetic accelerator cannon were not the Sky Rocket Battleships, but the Vortex Frigates.

The commander of the 4th Army Fleet of the Dion Expeditionary Force was Major General Ankore. When the army was ambushed, he immediately ordered the entire army to evade the attack.

"General, eight frigates of the Sky Rocket Battleship and the Whirlpool Frigate were hit by the electromagnetic accelerator and have completely lost all their ability to move."

"Tell them to abandon the ship immediately, and all Ms and mobile fortresses to attack."

"General, the missile swarms of the Tianyi Mercenary Group are attacking us in waves."

"Turn on the point position system and anti-missile system. Make sure to shoot down all their missiles from a distance. Also, calculate how many kilometers away the enemy is from us."

Tianyi attacked the 3rd Army, launching missile swarms one after another, and the shield-breaking destroyers continuously fired electromagnetic accelerator cannons.

Dion's 4th Expeditionary Force had all its warships dodge and launch anti-missile missiles and anti-missile beams.

In addition to the shield-breaking destroyers, armored frigates, Archangels, La Kailum and various types of modified early warships, the warships on the side of the Tianyi expeditionary 3rd Army also included another huge Ms mothership.

It is 630 meters in length and over 200 meters in width. The ship is surrounded by various types of weapons as densely packed as a mountain of swords, including a twin-mounted Mega Particle Turret and a multi-purpose large missile launcher of the same level as the Ra-Kailam class.

Moreover, this Ms mothership has 4 large Ms hangars, which doubles the MS maintenance capacity. It can carry up to 48 Ms and more than 80 Ms in wartime. Up to 16 Ms catapult decks allow the Ms troops on board to quickly complete combat deployment.

The name of this Ms mothership is Rebil.

The Tianyi Mercenary Group would develop the Rebil, mainly because the battleship had undergone a series of modifications. Although the hangar had increased the carrying capacity, the destroyer and frigate could only barely carry 20 Ms even in wartime.

This problem was discovered during the simulated battle between the Red and Blue armies, and the severity of the problem was further exacerbated during the actual combat with Dion's army.

The carrying capacity of the Dion Army's Ms warships is at least 50 Ms.

Although the Skywing Mercenaries had made some modifications to their existing warships and enlarged the hangars, the gap in carrying capacity between them and the Dion Army's Ms.

If it weren't for the electromagnetic accelerator cannon, mobile drill missile and Minov particle missile as the first attack tactics.

First, inflict severe damage on the enemy, and then block the enemy's radar, communication facilities, etc.

The Ms. Dion Army and the mobile fortresses, which are equally powerful as them, will definitely defeat them in terms of numbers.

Therefore, in the battle between the Tianyi Mercenaries and the Dion Army, even though the two sides were of equal size, the Tianyi Mercenaries first inflicted heavy damage on the Dion Army's warships.

The Dion Army can rely on the carrying capacity of its warships to narrow the gap in the number of Ms and mobile fortresses that the Skywing Mercenary Group sent out without any damage to its warships.

This is also the reason why the Tianyi Mercenary Group would lose more than 30% of their troops even after winning many battles.

Therefore, in order to solve this problem, Long Fei took out the design drawings of the Ms. Rebil mothership and built several ships first to conduct a simulated battle between the Red and Blue Armies.

It can indeed solve the problem of carrying capacity, although there are no super weapons such as super particle cannons and electromagnetic accelerator cannons.

Although the price of Ms. Rebil mothership is more expensive than Ms. La Kairam and Ms. Archangel mothership, it is at least much cheaper than shield-breaking destroyers and armored frigates.

The Ms. Rebir mothership is worth 80 billion Earth Coins.

There are currently 15 Ms. Rebil carriers in service and 28 under construction.

In the recent battles of the Tianyi Mercenary Group, every time they submitted a reimbursement form to the United Army, they would definitely take out nearly 30% of the reimbursement fee and invest it in the construction of the Ms. Rebil mothership.

The Tianyi 3rd Suppression Army had 4 Ms. Rebil motherships, each carrying nearly 90 Ms.

In order to avoid the electromagnetic accelerator cannon, the point defense systems and anti-missile systems of all warships of Dion's 4th Army were affected, resulting in a drop in accuracy and hit rate.

However, the attacking Ms troops and mobile fortress troops rushed to the location of the Tianyi Suppression 3rd Army, and tried their best to shoot down the attacking missile group.

However, there was a sudden surprise attack from the rear.

Several waves of mobile drill missiles and Minov particle missiles launched a surprise attack on the rear of Dion's 4th Army.

Major General Ankolei couldn't believe how the Tianyi Mercenary Group knew their whereabouts and ambushed them along their sailing route.
