The Angel's Tears' plasma engines quickly propelled the eight-kilometer behemoth into maneuver, followed by a salvo of three macro guns and dozens of bombardment guns on one side of the hull.

The huge plasma warhead accurately hit the battleship class at a rapid speed across tens of thousands of kilometers, and the exploding blue plasma directly tore through the shells of the battleship class, burning their interiors to ashes.

The light spear turret on the back of the Angel's Tears turned slightly, and the light of death descended on the betas. The high temperature of the light spear directly burned the battleship class, and the battleship class that was hit directly lost its ability to move and became a corpse floating in space.

Finally, the BETA class launched a counterattack, and a beam of light with a power similar to that of the Heavy Light class shone on the Angel's Tears' Void Shield, and then was engulfed by the shield, failing to make any waves.

The BETA's attacks failed to defeat the battleship-level Void Shield, but the Macro Cannon and Light Spear could easily turn the BETA into space junk.

Manipulating by the Mind class on the moon, the battleship class launched a near-suicidal attack on Angel Tears. Under the attack of the Opalon battleship's various firepowers, the BETA battleship class was almost completely wiped out in just a few hours, and the damage they caused was that the Void Shield of the Angel's Tears dropped by 5 percent, but after three minutes the Void Shield was filled again.

The Beta lost almost all of their mobility in the Earth-Moon system, but only caused a negligible loss of energy for the Expeditionary Force, plus a hapless bastard who was slightly scalded while charging the Void Shield.

Next, no matter what Horus's ships do in the Earth-Moon system, the BETA can only watch for a short time, and let the expeditionary force do whatever they want.

Horus, on the other hand, was worried in the conference room aboard the Angel's Tears. He wants to completely rid the moon of the BETA threat, but can't find a way not to destroy the moon at the same time.

Extinction orders will usually use vortex torpedoes or virus bombs to wipe out a planet's biosphere. The former will blow the moon to pieces, and the latter cannot be used on the moon without an atmosphere. But it is also impossible for Horus to send a Space Marines to the death of a beta lair thousands of meters deep on the moon. The Astartes of Horus are limited in number, and only an idiot would throw the elite military power at hand on the enemy's home turf and endless cannon fodder to grind meat.

Just as Horus was wondering what to do, the Sage of Clecisis offered him a solution.

"Genetic Virus Bomb" Horus flipped through the data board at hand, "Does this really work, Sage?" ”

"According to my simulations, there is an 87.5 percent chance that the virus will completely wipe out the alien creatures on the moon." The Sage of Cleixis answers Horus's question.

"Then do it, Sage."

On the torpedo deck of the Angel's Tears, a special torpedo is being prayed, and a mechanical priest stands in front of the torpedo and recites the binary word aloud.

“omnisiah immortālis，audiās nostram precem”

“sumus tuī puerī，multī scholasticī in māchinica viā”

……

After a long series of mechachanistic fragments, the torpedo was finally slipped into the launch pipe, and the mechanical priest pressed the torpedo launch button in the sound of prayers.

The extermination torpedo dragged a long trajectory towards the target, eventually exploding on the surface of the moon. The grayish-black powder diffused at the site of the explosion and subsequently covered the surface of the moon.

The beta on the surface of the nest brings the long-incubation highly contagious virus in the powder back to the depths of the nest. One beta was transmitted to another, and physiological testing of the beta did not detect any abnormalities.

In just a few hours, this highly contagious virus seeped from the surface of the nest into the deep layers, even the Mind and Total Mind levels.

After waiting for the virus to spread sufficiently, the Sage flipped a switch on the console, and a string of signals was sent to the moon. The virus in the body of the infected beta also reacts. The virus begins to violently attack BETA's flesh, causing muscle dissolution, internal bleeding, organ failure, and a cascade of illnesses that causes BETA to die quickly, leaving a mess of flesh and sludge behind. If someone enters the BETA lair now, then he will be drowned in the flesh sludge.

Horus, who had observed the tragic state of the BETA on the moon through an optical device, asked the Sage of Clecisis in a strange tone.

"Is that really a genetic virus weapon, Sage?"

After a moment of silence, "That's a variant of the virus bomb, my lord." ”

Horus glanced at the sage meaningfully, "I believe in you, don't let me down. ”

With that, Horus left the observation deck to discuss his next strategy with the Space Marine Company Commanders.

The little secret of the sage of Cleixis was not unexpected by Horus, how could he be arranged by the emperor to join the expeditionary force without a little peculiarity? Horus himself is half a junior, Sage Clecisis is mostly a technical heretic, and a few of the Space Marine Company Commanders have their own careful thoughts.

However, Horus doesn't care, as long as he doesn't cross the bottom line or interfere with strategic planning, he won't interfere too much with these little secrets, and think carefully.

The only thing Horus needed to do was to unite all of his men. No matter what the purpose is, as long as it can ultimately safeguard the overall interests of mankind, bring victory, and achieve Horus's goals, then Horus will let go and do it.

After the extermination order, Horus's expeditionary force has won a great victory in the Earth-Moon system, and the BETA's fleet has been crushed, and all the BETA on the moon have become a mess of flesh, and they can no longer be a threat.

Now, Horus can deal with the beta disaster on Earth with impunity, and there is no doubt that the beta is no longer a crisis, and the offensive of the expeditionary force has given the human military power an overwhelming advantage before the Earth-Moon BETA can be supported.
