The all-out attack of the Zerg has brought a painful disaster to all galaxies in the universe, countless creatures have been displaced, tens of thousands of planets have been conquered, and the aliens who can resist this attack are only a few after all.

The battle situation is becoming more and more difficult, the number of Zerg seems to be endless, and even the Earth Federation has urgently recruited a group of personnel and civilian spaceships to send supplies and supplies to the front-line fighting fleet.

"Lord Death, the drone units of the three fleets have all been destroyed, and the intelligent machinery units have also suffered a lot of damage, do you want the headquarters to replenish more?" Leohard asked, the dark circles on his face were heavy and he looked very haggard.

Mu Chen sighed and said: "The ordnance manufacturing department is already in a hurry, but it will take three days to complete the production of the first batch of drones at the earliest......"

"It's not okay to go on like this, the reptile doesn't have the concept of retreat in his head at all, and many kinds of laser weapons on the battleship have been damaged due to long-term continuous combat."

Mu Chen also knows this situation, there is a big problem with energy weapons, they cannot be used continuously for a long time, they must be cooled down every once in a while, otherwise the heat energy generated when fired will have a serious impact on the weapon itself, and even be damaged.

But now the swarm is like crazy, desperately attacking the defense line of the solar system, not giving the fleet any respite at all, and most of the weapons on the battleships are overloaded, and it is impossible to have time to cool down.

"Organize maintenance troops to seize the time to rush to repair, and maintain the intensity of the attack no matter what." Mu Chen said coldly, "This should be the last counterattack of the insect swarm, as long as you hold on to this time, it will be much easier next." ”

In fact, Mu Chen's heart is not at the bottom, the reconnaissance satellite sent out cannot detect the scale of the insect swarm at all, and after flying a distance of several light years, he still can't see the edge of the Zerg troops, God knows where so many insects came from.

Mu Chen can only comfort his subordinates in this way, otherwise once the morale of the crew starts to drop, everything will be over.

Leohard knew this, but like Mu Chen, he couldn't think of a good solution.

"Why don't we fire another black hole bomb? This will buy some respite. Leohard suggested in a whisper.

Mu Chen frowned, and refused without hesitation: "No, cracks have already appeared in the space of this star field, once the black hole bomb is used again, it is very likely that a permanent black hole will be created here, which is tantamount to drinking water to quench thirst." ”

You must know that this is the edge of the solar system, and behind him is the home of the earthlings, Mu Chen does not want to bury a huge hidden danger at the door of his home, because that is the way to die.

Leohard sighed, how could he not know the danger of such a distance, but other than that, there is really no good way, the crew has been fighting for a long time, even if there is a chance to take turns to rest, it is not enough to recover physical strength, often just replenish food and water, and before they have time to sleep for a few minutes, they receive the order to go up again.

After all, people are not machines, and in this state of fatigue, the combat effectiveness decreases significantly, the reaction speed also becomes sluggish, and the number of casualties is increasing.

Mu Chen anxiously looked at the tumbling swarm in front of him, struggling incomparably in his heart.

At every turn, warplanes crash in engagements, and even warships are in danger of being breached, even the energy shield on the Reaper

It has also reached the point where it is precarious, and the Earth Fleet will not be able to hold out for long.

"Lord Death, good news!" The intelligence officer shouted excitedly, "The Celestial Sword Shore Defense Cannon we built on Pluto has been completed, and it is expected to move to the intended orbit in 15 minutes!" ”

"Great! It's finally here! Mu Chen waved his fist excitedly and cheered up again, "Pass my order, and all units will take cover alternately and retreat to the vicinity of Pluto." ”

The flying unit immediately began to move after receiving the order, the thrusters sprayed forward and slowly retreated to the rear, while the laser cannons and other weapons were always aimed at the insect swarm in front of them, constantly weaving a net of fire.

"How long will it take for the Star Destroyer to cool down?" Mu Chen asked.

[It is estimated that it will take 7 hours and 32 minutes to return to normal state...... intelligent assistance system reported truthfully.

Mu Chen was ruthless: "I can't wait any longer, I must charge the two Star Destroyer cannons immediately, and we must create a chance for the troops in front to retreat!" ”

[The Star Destroyer Cannon is forced to start, it enters the charging state, it is expected to be ready in 15 seconds, please note that the weapon is in an overload state, and the forced start will cause irreversible failure, please deal with it properly......]

"The maintenance team should do a good job of damage management, and once they find that the Star Destroyer Cannon has signs of collapse, immediately abandon the weapon!"

All structures on the Reaper are modular, and any part of the body that is abnormal can be discarded directly, leaving this part separate from the main body to avoid martyrdom.

And Mu Chen was already desperate, even if he sacrificed these two precious Star Destroyer cannons, he had to create an opportunity for the flying troops fighting in front to retreat.

The two Star Destroyer cannons lit up with a dazzling blue light again, and Mu Chen controlled the Reaper to the front line of the battle line, taking over the several fighters that were dragged by the swarm here.

"Hurry up and evacuate the flight troops, don't waste time!" The familiar voice of the Reaper brought tears to the eyes of every space pilot, and their Reaper always stepped up to the occasion at the most dangerous moment of battle to stop the enemy without hesitation.

It is precisely because of this that Lord Death will be regarded as a divine residence by the crew and respected from the heart.

The flying troops came to speed up the retreat, and gave up the line of battle to the Grim Reaper to confront.

Everyone had already guessed what Mu Chen was trying to do, and the two Star Destroyer cannons that lit up again said it all, and the Grim Reaper was about to wield his giant "scythe" that harvested the lives of his enemies again.

After the Black Hole Bomb eliminated most of the Zerg's planetary bases, Mu Chen no longer used the Star Destroyer Cannon to attack key targets, but tried to use it to kill as many living forces as possible of the swarm.

As Mu Chen pressed the launch button of the Star Destroyer Cannon, two giant pillars of light were launched, and the swarms of insects along the way were instantly turned into powder by these two pillars of light, directly opening up two passages in the crowded army of insects.

The bases of the two Star Destroyers rotate to the sides, expanding the area covered by the energy pillars as much as possible.

There seemed to be a huge folding fan slowly opening in the swarm, and none of the zerg that it touched survived, and even the huge eight-winged flying snake was directly split in half.

The crews of the Federation fleet seemed to see the real Grim Reaper, wielding a scythe to harvest life in the swarm, and the area where the pillars of light of the Star Destroyer Cannon swept by,

The swarm seemed to have evaporated, and disappeared in an instant.

[Warning, warning! The No. 2 Star Destroyer Cannon has an abnormality and is about to collapse, please deal with it in time! 】

Mu Chen sighed, it seemed that he could only go so far.

"The maintenance team immediately shut down the No. 2 Star Destroyer Cannon and disconnect the Star Destroyer Cannon module from the main body of the Reaper!"

"The maintenance unit received! Executing! ”

With a crisp "click", the mechanical claw used to fix the base of the No. 2 Star Destroyer opened at the same time, and the No. 2 Star Destroyer received the thrust from the base, quickly detached from the main structure of the Reaper, and flew towards the swarm of insects in front.

"Hey, it feels a bit of a pity, this Star Destroyer cannon is not cheap, and it can even top a large space carrier." A maintenance soldier said regretfully.

"There's no way, if you don't get rid of it now, if it explodes in a while, I'm afraid the Grim Reaper will have to be destroyed too." The teammate next to him also said helplessly.

"Abandon the pawn to protect the handsome, I don't think it's a loss, it's a big deal to find a chance to recycle it back in the future."

"No kidding, the entire barrel is about to melt down by the heat, and it's useless to recover it."

Just as a few maintenance soldiers were talking in a low voice, a violent shaking came.

"The second squadron of the maintenance unit, conduct a comprehensive inspection of the bow of the Reaper, and be sure not to miss any hidden dangers!" The command sounded inside the helmet of each maintenance soldier at the same time.

"Captain, what's going on?"

"Don't be nervous, the No. 2 Star Destroyer exploded after disengagement, fortunately it reacted in time, otherwise the Reaper would be in danger, now it's just a routine inspection, Lord Reaper is worried that the hull will be accidentally injured by the fragments of this explosion." The captain explained lightly.

"Huh, it's so hanging, can we be considered to have escaped again?" The maintenance soldier asked with trepidation.

"Look at your little bit of talent, I've served on the Grim Reaper for so many years, and I haven't seen you train your guts." The teammate teased disdainfully.

"You still have the face to talk about me? Take care of yourself first, and see how ...... your legs tremble."

"I'm excited!"

Only Mu Chen knew best how dangerous it was just now, and at the same time as the alarm sounded in the auxiliary system, the crisis warning came again.

Mu Chen immediately ordered the No. 2 Star Destroyer Cannon to break away from the main body, but even so, it was still affected by the explosion, and the remaining energy of the Star Destroyer Cannon exploded, directly consuming 30% of the shield's energy.

Mu Chen couldn't remember how many times the talent of crisis warning had saved him, so much so that he almost liked the feeling of being reborn after the catastrophe.

"Alright, the swarm has been held back for the time being, let's hurry up and retreat." Mu Chen commanded lightly.

Several people in the command room looked at each other silently, and they sincerely admired in their hearts, maybe only Lord Death could recover from the feeling of escaping death so quickly.

[Pluto has arrived at the predetermined position, and the Celestial Sword Shore Defense Cannon is ready to join the battle at any time. 】

"Hmph, I want to see if these insects are really fearless," Mu Chen said with a sneer, "Pass my order, the Heavenly Sword Shore Defense Artillery is fully fired, give me a hard fight!" Let these bugs show you the power of earthlings! ”
