Defense Fortress No. 077

"Report! The No. 3 machine gun is overheating again!" the soldier shouted hurriedly.

"If it overheats, replace the gun barrel!"

"Put the replaced gun barrels into the coolant to speed up the cooling process!" shouted the fortress commander.

The soldier immediately began operating the robotic arm to remove the overheated, red-hot cannon barrel and place it into the coolant that had been prepared nearby.

Hiss hiss hiss

When the hot gun barrel is immersed in the coolant, a hissing sound can be heard.

This method allows the overheated barrel to return to normal temperature within a short time before it can be used again.

However, there is a drawback.

That is, after repeated cycles, the lifespan of the gun barrel will be greatly shortened. If it reaches its limit and is not replaced and continues to be used, there may even be a risk of barrel explosion.

The fortress commander shouted through the internal communication channel: "I'll emphasize it again, remember to check the wear and tear of those cannons after they've been cooled down!"

Any item whose wear and tear exceeds the standard should no longer be used!

If cracks exceeding the required standards are found on the barrel, it must no longer be used.

You must be extremely careful, very careful indeed!

"yes!"

Upon hearing his subordinate's voice, the fortress commander took off his hat, fanned himself, and unbuttoned a few buttons on his collar, all the while cursing, "It's fucking hot!"

What's wrong with the temperature control system? The temperature's already over 30°C!

"Sir, there's nothing we can do about this."

Except when changing cannon barrels, all the weapons in our fortress are firing non-stop, which causes a surge in heat.

Furthermore, a large amount of heat is also generated when cooling the overloaded gun barrel.

"Well... there's nothing we can do about it," the sergeant in charge said innocently.

"Damn it." The fortress commander muttered, but did not pursue the matter further. He walked to a porthole and looked at the battlefield in the distance.

He could also magnify distant images using a telescope mounted on the porthole.

He saw countless Zerg combat units being torn apart by their barrage of bullets.

But then even more Zerg combat units will swarm in, as if they can never be defeated.

Meanwhile, the occasional T1 and T2 level Zerg motherships that do appear are precisely targeted and killed by starships, never having a chance to demonstrate their strength.

At the beginning of the war, it seemed as if they were on the defensive.

However, all the commanders of the defensive positions knew very well that this was only the beginning.

Nearly ten hours.

Their main position suffered few losses.

The problem is that they only managed to annihilate less than one-tenth of the enemy's forces!

In this situation, the offense and defense are merely maintaining a balance.

If any unexpected event occurs at the main position, especially if there is a shortage of military supplies leading to insufficient firepower, the situation will change instantly.

"How on earth do these bugs breed? There's no way we can kill them all!" the fortress commander muttered.

T5 Dragon Emperor Starship - Bridge

"The battle has been going on for ten hours so far."

Of the 500,000 Zerg motherships, we destroyed nearly 50,000; we also eliminated nearly one-tenth of the Zerg combat units.

Meanwhile, approximately 50,000 Zerg motherships, carrying their own Zerg combat units, have already bypassed our flanks and will soon encounter our smaller rear positions.

Given the current situation, there is no major danger.

Our combat supplies are also going smoothly, at least for now.

The other nine main positions have also entered the battle.

On average, those main positions faced around 200,000 Zerg fleets. The second largest number of Zerg fleets faced by us were the Holy Light Empress Fleet Group and our Eighth Legion of the Wyvern, which faced 350,000 Zerg fleets.

But so far, everything is going smoothly. Little Dragon Girl floated behind Zhao Chen, placing her hands on his shoulders.

"Based on this data, the total number of Zerg fleets that have entered combat with us so far is nearly three million."

This only accounts for one-tenth of the enemy's 30 million Zerg fleet.

"And none of the eleven T5 Leviathan-class Zerg motherships have been deployed yet," Zhao Chen said, squinting.

He stared at the eleven brightest energy points on the interstellar war sandbox, which were evenly distributed around the cosmic wormhole.

But there has been no clear direction.

"Yes.

We have observed the movements of the second Zerg fleet, but the direction of their attack has not yet been determined.

Once the direction of the enemy's second wave of Zerg fleet is determined, we can respond accordingly.

"We have at least five hours to respond," Little Dragon Girl said.

“It seems that there must be a commander behind this invasion,” Lilith suddenly analyzed from the side.

Commander.

For a long time, the Zerg have been seen as an interstellar race that launches invasions based on its killing instincts.

Although the Hive Mothership possesses a certain level of intelligence, even the known T4 Hive Mothership's intelligence is limited to inducing its fleet to abandon its offensive instincts and retreat.

To make detailed battle plans, one needs even greater wisdom.

Could it be that the Zerg invading this time possess such intelligent beings?

Are they those eleven T5 Leviathan-class Zerg hive motherships?

Zhao Chen's intuition told him that it probably wasn't.

The worst-case scenario is that behind this interstellar Zerg invasion lies an even more intelligent entity.

Regardless of what kind of creature it is, if it can truly command a 30 million interstellar Zerg fleet and possesses extremely high intelligence...

That is undoubtedly a major threat!

However, there are currently no clues, so we can only take it one step at a time.

At the very least, we must ensure that no mistakes are made on our side in the current operations.

Next, ten hours... twenty hours... thirty hours... fifty hours...

One hundred hours...

During this process, the second and third waves of attacking Zerg fleets were also very evenly distributed across various battlefronts.

Zhao Chen sat in the captain's chair with his eyes closed.

"Commander, why don't you go back to the captain's cabin and rest for a while?" Lilith looked at Zhao Chen with concern.

During this period, the commander was always on the bridge, spending most of his time in the captain's chair, or occasionally walking around the bridge.

Resting was simply leaning back in the captain's chair, closing my eyes, and taking a nap.

It should be noted that other crew members are arranged to rest in three or two shifts.

That's one way to put it.

Here, only the commander never left the bridge.

"It's been a hundred hours."

We have destroyed nearly three million Zerg motherships.

"What are those bastards waiting for?!" Zhao Chen muttered, frowning.

Lilith, standing to the side, watched the still-intense interstellar war sandbox and didn't know what to say.

This calm stalemate only exacerbated their unease!
