Unfortunately, the defense mechs that had just formed a shield were instantly riddled with holes under the concentrated fire, and one by one, they fell into the starry sky.

Immediately afterward, the penetrating fire landed on Dusk Fortress and exploded.

Instantly, the entire Dusk Fortress was like being washed by fireworks, exceptionally dazzling.

Inside the command room of Dusk Fortress, the robot, Kanon, while furious, began to feel somewhat apprehensive. It constantly uploaded code instructions.

At that moment, many secondary weapons on Dusk Fortress adjusted their attack targets, temporarily abandoning the attack on Qianchengxue.

In an instant, dense firepower shot down incoming mechs and interstellar fighters in swathes.

But even so, subsequent support troops still涌上来 (yong shang lai- rushed up) like a flood. Even the worst ships, regardless of danger, came up to fire a few shots at this big guy, Dusk Fortress.

At this moment, Dusk Fortress was like a tiger entangled by termites, as aggrieved as it could be.

Just then, a brilliant light streaked across the starry sky.

Instantly, it bombarded Dusk Fortress, and the entire Dusk Fortress shook violently!

The saying, "He who spends his days hunting geese will one day be pecked in the eye by a goose," was vividly displayed at this moment.

The Black Obsidian's main cannon completed its energy accumulation again, delivering a ruthless blow. The armor of the Dusk Fortress at the point of impact was melted into a large hole, but it did not penetrate, which shows how thick the surface armor of the Dusk Fortress is.

However, the personnel who came up to attack, seeing this, rushed towards the melted area, bombarding that area wildly.

Instantly, Dusk Fortress moved, actively evading attacks.

In the public battle channel, many people cheered excitedly when they saw this.

"Brothers, go! It hurts..."

"That's right, it's time for revenge."

......

At this time, on the side of Dusk Fortress, Lin Ming and Kalinsa led a team of GT department's elite squad, quietly sticking to Dusk Fortress.

The mechs on their backs carried special electronic interference devices, which interfered with Dusk Fortress's scanning devices to a certain extent.

In addition, Dusk Fortress's attention was now focused on the main battlefield, and it didn't notice anyone sneaking up.

At this moment, Lin Ming and Kalinsa manipulated their mechs, opened the metal boxes they carried, and exposed specially made HSW-03 tactical nuclear mines—Embracers.

They took them up one by one and attached them to Dusk Fortress.

They installed more than ten HSW-03 tactical nuclear mines—Embracers—in one go.

The power of the explosion, one could imagine how terrifying it would be.

Kalinsa smiled and said in the communication channel.

"Installation complete, let's withdraw. It's time for this big guy to taste our gift."

"Everyone withdraw!"

Lin Ming responded without hesitation.

Instantly, the mechs that had completed their work quickly detached from Dusk Fortress.

At the same time, all the tactical nuclear mines on the surface of Dusk Fortress were activated, and a countdown began to appear on them!

"59s"

"58s"

"57s"

.....

At the moment when the countdown reached zero.

Rumble~

One dazzling sun after another exploded on the side of Dusk Fortress.

The entire Dusk Fortress command room shook violently.

One red alert box after another popped up.

"Warning: Area D of the fortress is severely damaged."

"Warning: Decompression in progress."

"Warning: E243 circuit damaged."

......

The robot, Kanon's mechanical electronic eyes flickered with an unusual red light, and it felt a strange fear.

Dusk Fortress's tortoise shell had been pried open, and the opponent's returning defensive forces were increasing. If they continued to fight, they might be lost here.

So the robot, Kanon, instantly issued a series of instructions.

The defense mechs and mechs operating on the periphery began to diverge into two extremes. Some began to attack suicidally, while others began to retreat and gather.

Even the two Mechanical Executioners that were holding back Qianchengxue began to retreat.

On the other side, Su Mo was entangled with a Mechanical Executioner. He controlled the Liehu, slamming his spear again and again at a point seven inches below the Mechanical Executioner's right chest.

The Mechanical Executioner's movements became increasingly stiff, and some internal conduction component seemed to have malfunctioned.

Su Mo's heart became more and more heated. The Faker—Devourer was too awesome. It could accurately find the weakest part of the opponent's body. Compared to biological mechs, pure mechanical mechs, although balanced, also had fatal flaws, that is, key components could not be damaged, but under normal circumstances, no one could find them.

After all, who could understand so clearly the internal structure of an IV-generation pure mechanical mech with an extremely complex structure?

Just then, the Faker—Devourer suddenly said to Su Mo.

"Retreat quickly, as far as you can!"

Su Mo's heart skipped a beat. Although he didn't understand why he had to give up the fat meat that was about to be in his hands, he still followed the optical computer's advice immediately.

He jerked the control lever and quickly backed away.

The Mechanical Executioner in front of him began to spark with electricity, and the internal core temperature soared.

Su Mo saw this scene and retreated frantically!

Boom~

In the next second, the IV-generation pure mechanical standard mech—Mechanical Executioner—in front of him exploded instantly.

The entire III-generation mech—Liehu—was only affected, and flew out like a meteor.

Su Mo's head slammed hard against the back of the chair, and he couldn't help but grit his teeth in pain.

"Hiss~ That's ruthless!"

......

Inside the Black Obsidian command room, the operator happily reported.

"The assault team successfully completed its mission. The damage to Dusk Fortress has reached eighteen percent!"

"Report, IV-generation pure mechanical mech—Mechanical Executioner No. 1—was defeated and destroyed by Su Mo!"

"Report, our mobile forces are rapidly eliminating the enemy forces."

.....

One good news after another kept coming.

At this time, Putnam suddenly reminded, "Something's wrong, Li Ruqi, take a look. Is the enemy contracting their forces? Is this guy trying to escape?"

Li Ruqi took a closer look, and his eyelids twitched. He immediately issued a stern order.

"The opponent wants to escape. Everyone listen to my orders, absolutely do not allow the opponent to escape. Find every possible way to stop it for me! If we can take down the opponent, all our losses this time will not only be compensated, but we will also achieve a qualitative leap!"

He was joking. The entire Dusk Fortress was so huge. No one dared to imagine how many resources were stored inside. And maybe they could also obtain the manufacturing technology of the IV-generation pure mechanical standard mech.

Even if we take a step back, Dusk Fortress is just an empty shell. It's such a large volume. The various equipment and cannons on it, as well as the armor, are enough to make a fortune if dismantled.

So many people died and were injured, how could he let it escape so easily?

"Yes!"

Everyone present responded excitedly when they heard Li Ruqi's words.

The order was quickly transmitted to everyone, and everyone was as excited as if they had been injected with chicken blood, attacking Dusk Fortress frantically.

At this time, the huge Dusk Fortress was also going berserk!

It all depended on who was more ruthless than whom.

Ka~~

Countless close-in defense cannons extended out, firing furiously at the incoming enemies.

At the same time, the entire fortress began to retreat.
