Chapter 933: Cosmic Rust Gun (Please Subscribe)

New Iacon, on the Ziyou Guangchang outside the city hall.

Optimus Prime was currently brandishing his Heavy Sword, engaging in close-quarters combat with his teacher, Sentinel Prime.

"Teacher... I once thought Frenzy was lying, but you have disappointed me..."

Sentinel Prime easily blocked Optimus Prime's Heavy Sword with his Shield; feeling the force transmitted through the shield, the expression on his face grew even gloomier.

"My student!" He exerted sudden force, using the shield to knock Optimus Prime flying.

Then, brandishing a long blade that looked like a warship's protective plating, he slashed toward Optimus Prime, not forgetting to preach at the same time: "You must realize that Autobots who yearn for so-called peace are not qualified warriors. Therefore, we have only one dead end in the war against the Decepticon Legion. To change this outcome, someone must make sacrifices!"

"So, you betrayed us, betrayed the Autobots!"

Optimus Prime narrowly blocked his slash; Sentinel Prime's immense strength forced his body to retreat two steps before he could stand firm.

Sentinel Prime raised his blade to slash at his former student again, while shouting angrily: "Betrayal? No, I simply made a deal with Megatron!"

With immense power, Sentinel Prime slashed at his student, using his full strength this time.

Optimus Prime was caught off guard; when his Heavy Sword collided with the long blade, the tremendous force immediately knocked the weapon from his hand, and his entire body was sent flying by that massive impact.

"My student... as a Commander, you are absolutely qualified!"

Retracting the hand holding the long blade behind his back, Sentinel Prime sneered as he pulled a long gun from behind him and aimed it at Optimus Prime.

"But as a Leader, you are absolutely unqualified!"

Without hesitation, he pulled the trigger; that special weapon, which looked exactly like a shotgun from Earth, fired a sandy-yellow energy mass from its muzzle, which quickly slammed into Optimus Prime's body.

"No..."

Ironhide, who was fighting not far away, saw this scene and his eyes immediately split with rage.

Sentinel Prime watched his former student, who was looking at him in disbelief, with an expressionless face, his heart completely unmoved.

"Goodbye, my student!"

Then, raising the weapon in his hand—the Cosmic Rust Gun—once more, Sentinel Prime pulled the trigger twice more under the gaze of several Autobots who had broken free from their opponents and were trying to rush over to protect Optimus Prime.

"Bang... bang..."

Sentinel Prime's weapon—the Cosmic Rust Gun—could be considered one of the greatest achievements the Autobot faction had ever attained.

When the Cosmic Rust Disease struck back then, almost all silicon-based life in the galaxy similar to the planet Cybertron suffered a fatal blow.

This special disease, whose origin and cause no civilization has been able to explain clearly to this day, possesses astonishing corrosiveness toward all metal.

Once any metal is contaminated with this Rust Disease, it rusts rapidly, soon becoming a pile of rust-dust that crumbles at a touch.

The history of the Cybertronian civilization has also encountered the Cosmic Rust Disease twice; the first recorded instance occurred during the period when the Quintessa Civilization colonized Cybertron.

Because of the arrival of the Cosmic Rust Disease, that Quintessa Civilization, which was once powerful enough to wage war against dozens of powerful civilizations in the galaxy simultaneously, had to accept a defeat that almost led to their extinction.

It was precisely thanks to that instance of the Cosmic Rust Disease that the Cybertronians not only successfully defeated the Quintessa colonists but also reclaimed their home planet.

Furthermore, because of the Quintessa Civilization's great retreat, they took the opportunity to acquire a vast amount of Quintessa technology and the former alien colonies of the Quintessa people.

The Cybertronian civilization leaped from being a colony treated like meat on a chopping block to becoming a powerful cosmic civilization.

When that instance of the Cosmic Rust Disease arrived, the Cybertronian civilization did not suffer too severe a blow.

However, the second Cosmic Rust Disease almost destroyed the Cybertronian civilization.

At that time, it was the end of the first Cybertronian Civil War; the Decepticons and Autobots were still fighting tooth and nail for control of the planet Cybertron due to their differing ideologies.

The Cosmic Rust Disease arrived at this very moment, just as eerie and just as overbearing as it was during its first arrival.

The first to be infected was a wounded soldier from the Autobot faction; while receiving treatment in the rear, his body, which was almost recovered, suddenly deteriorated and completely rusted within a short time, turning into a pile of rust-dust.

Following that, the Cosmic Rust Disease broke out one after another within the two major factions, the Autobots and the Decepticon Legion.

In an extremely short time, over thirty percent of the Decepticons and Autobots died rapidly due to the Cosmic Rust Disease.

In order not to be completely exterminated, the Decepticon Legion and the Autobots finally signed a hasty ceasefire agreement, ending the first Cybertronian Civil War.

Afterward, both major factions invested massive amounts of manpower and resources into researching methods to prevent and completely eradicate the Cosmic Rust Disease.

The result was that none succeeded; in the end, both the Decepticon Legion and the Autobots had to adopt a method of hibernation, using stasis and time to combat the Cosmic Rust Disease.

Of course, that was only the official explanation.

At least a few high-ranking Autobots knew that their scientists, through continuous treatment of Cosmic Rust Disease patients, had finally analyzed a small amount of the Cosmic Rust Disease's molecular structure and, on that basis, created a special induction energy that simulated the Cosmic Rust Disease.

Sentinel Prime's weapon—the Cosmic Rust Gun—was a dangerous weapon of mass destruction designed using that special induction energy.

A single shot was all it took; even an Elite Warrior would be instantly severely wounded, and the wound would begin to rust rapidly, soon leading to death.

Because it was too vicious, the Autobots of the past only manufactured one such weapon and entrusted it to Sentinel Prime to use.

Watching Optimus Prime, whose body was beginning to show large areas of rust and whose life was clearly fading, Sentinel Prime's face remained calm.

"It is ironic, to say the least; you were the one responsible for supervising the manufacture of this weapon, my student... and now, you have died by its hand..."

Casually raising his shield, he blocked a grenade fired in anger by Ironhide.

Sentinel Prime glanced at him but did not deal a lethal blow to Ironhide.

"Autobots, prepare to sortie with me!"

After calmly issuing the order over the channel, Sentinel Prime turned and walked toward the direction of the blade-wielder.

And around him, the Autobots who were loyal to him were rapidly gathering toward Sentinel Prime.

Most of them were actually unwilling to be enemies with Optimus Prime and Ironhide, so they had mostly held back during the fight just now.

At this moment, seeing their former leader, Optimus Prime, lying not far away, his body rapidly rusting, clearly on the verge of death.

Some Autobots could not help but show expressions of unbearable pain, guilt, and sadness; carrying these complex emotions, they quickly followed Sentinel Prime as he retreated, soon leaving New Iacon and rushing toward the Beifei Diqu.

And their destination was none other than the banks of the Nile River, the capital of that ancient civilization with a long history—Cairo!
