The Great Heresy of Angron

Humans are made of iron, and food is made of steel. Like a certain dragon that loves to eat dirt, the Primarch is also a giant food incinerator.

Due to the underlying design, in order to minimize the probability of encountering danger in their infancy, the Primarch grows at an extremely fast speed, and their digestive function is beyond imagination.

Poisons that can cause sudden death, waste that cannot be considered food, and even wild grasses that offer little protein nutrition to humans can all serve as energy sources for the organism.

This model seems good, but it has a huge hidden danger. The Emperor did not take the growth of the Primarch into account at all, allowing the most important childhood period for the formation of values to pass by too quickly.

Coupled with the Yellow Skins's unbearable parenting experience, it's hard to say whether it's better for the original body to stay by his side or scatter across the galaxy.

As for your suggestion to let Malcador lead the team, forget it. Just look at Alpharius, a phenomenal God-Human, and you'll know that Malcador isn't exactly a normal person either.

But there's one exception: Angron, the unluckiest of the unluckiest.

Watching Mortarion frantically showing off his food, Mordred pulled out a Butcher's Nail and asked the question he most wanted to know, "How did Angron's true form end up on you?"

"I found it."

"Found it?"

"That's right, I picked it up, or rather, I picked it up from Angron's corpse."

Setting down his food bowl, Mortarion recounted a little-known secret. About 9,000 years ago, when he still retained a sliver of clarity and had roughly figured out what the Great Heresy was all about, it was already too late.

Because the Death Guard was completely trapped, Nurgle never let the Legion leave his sight, while Mortarion was fed soup by Nurgle every day.

"I don't even know how I survived. Every day was a nightmare, lasting for nearly a thousand years. I'd rather eat shit than drink that stuff."

I don't know what happened to the other brothers, but I'm the worst off. Some of them gave up, some went crazy, and due to long-term corruption, they can no longer go back to the empire.

The empire completely branded them as traitors, smearing them with all sorts of accusations, even when they weren't the ones who did it.

At this point, Mortarion subconsciously glanced at Guilliman remained silent, unable to explain this historical legacy.

"As you probably know, we could afford to slack off, but our legions couldn't. Over time, the legions' long-standing problems finally came to a head."

As far as I know, almost every rebel legion has experienced large-scale civil wars, which is exactly what the Chaos God want to see. They begin to slowly divide the legions from the grassroots, turning them into warbands and selecting the most suitable people for them.

The Legion was already acting strangely at this point, but it was still within the Empire's borders. Then it suffered Great Purge and was driven back into the Eye of Terror.

"That's because you've already been tainted by Chaos. I can't leave these ticking time bombs alone."

Guilliman was right. The splitting of the Legion into Chapter and the transformation of the Legion into Warcities occurred around the same time. No one knew what would happen after the Primarch was abducted by the Chaos God, or whether these Legions left behind in the Imperium were still under control.

In order to eliminate the danger and to adapt to the state of the empire at the time, Guilliman ultimately Split the Legions to ensure that there would be no more legions wreaking havoc on the empire like during the Great Heresy.

As for whether the legions whose Primarchs were abducted by the Chaos God were ostracized during that chaotic period, they certainly were, and not only were they, they were practically held captive.

"So later, a series of legions, such as the Iron Warriors and the Night Lords, broke out into civil war. Some returned to the Empire and went into hiding, while others fell into complete Chaos. My Death Guard was one of those legions that split off during that period."

"What about Angron?" Mordred asked.

Speaking of this, Mortarion's little face twisted into a rather distorted expression. "That's 1000 years from now, or rather, it's not exactly a secret, but I'll tell you in advance that no matter how outrageous what I'm about to say may seem, it's all true."

"Don't worry, no matter how outrageous your words may seem, we will believe you."

Since Mordred had said so, Mortarion then revealed the untold stories of the past. "Because Angron had completely given up on him, Khorne had abandoned him and wanted to send him back to the Empire, but instead of leaving, he was trying to reform Khorne!"

"What? Repent the Khorne!"

Mortarion nodded, indicating that was exactly the case. Angron recited poetry to the Khorne every day and led the World Eaters in a collective act of stagnation, saying things like, "True sincerity for true sincerity, if he doesn't go to hell, who will?"

That one was even more of a charlatan than Luojia, driving countless Khorne Daemons mad over a thousand years, converting them to the Imperial Truth, and eventually leading to a Chaos Great Heresy.

Mordred was stunned, Guilliman was stunned, and if Luojia were here, she would probably be stunned too. But then again, it made perfect sense; Angron did indeed have this ability.

"Wait, could the Daemon Father mentioned be these Daemons? Where are they?"

"It was probably eaten by Yellow Skins as a snack. What happened next?"

"Later, well, you can imagine what happened. Everyone else was just lazing around and acting crazy, but Angron was betraying his own side, so the Khorne took care of him, driving eight nails all over his body, and this was one of them."

However, I estimate that Angron had more than eight nails in his body. When I saw him again later, he had another nail in his buttocks.

"Huh? There's even a submissive/training scene!"

This information was so explosive that Mordred couldn't even imagine what the situation was like in Angron right now.

Because the nails couldn't be removed back then, Mordred took advantage of the situation and divided Angron into two parts, using the nails as pilots and their bodies as mechs, creating a dual-channel system.

Others might not see through this, it's all for the purpose of scheming against people, but it depends on who it is. If it falls into the hands of Chaos God and no one can see through it, then something is really strange.

But now Angron isn't a dual-SIM dual-standby anymore, it's an eight-SIM eight-standby. With so many thorns in his side, he's bound to go crazy.

"So, Angron has become like Ferrus, everything about him has been elevated to the Daemon Primarch, and his body has become Wetware of the Butcher's Nail. How do you know that?"

In response to Guilliman's question, Mortarion shrugged, indicating that he certainly knew the answer: the other three Chaos God were involved when Angron launched the Great Heresy, otherwise why would the Khorne have only one ear?

Seeing that the two still didn't believe him, Mortarion dropped some more bombshells, saying that Koz and Perturabo had also done this, and even that Ferrus was involved, and that Omega had tipped them off.

Mortarion smiled rather sheepishly, indicating that he was a key player. It was just a pity that Ferrus had suddenly started partying halfway through, Hydra was fighting with itself, Koz's assassination attempt failed and he was slapped away, and Perturabo ran away when things went wrong. Even now that we've been slacking off, she still calls us trash.

"What about the little horse?"

"Well, how should I put it? Little Ma is actually alright, pretty decent, it's just that his offspring, Ahriman, is a traitor. He destroyed the Crystal Maze with a single Psychic Power phone call."

Not only did the bomb leave Magnus partially paralyzed, but it also completely annihilated the Thousand Sons Legion, turning them into the current Redemptor Marines.

Mordred finally understood. None of them were human. No wonder Pepe. With this bunch of incompetent teammates, he'd tank too if he were in their shoes.

It's hard to say whether the Four Merchants were lucky or unlucky, but all of their original entities were kidnapped by God-Human, unlike him, who was the most normal person, skilled in both literature and martial arts.

But that wasn't all; Mortarion then added what Mordred had always felt was missing.

"Actually, Angron's reason for betraying the Khorne was rather strange. According to him, it wasn't for the Empire, but because he wanted to save the Khorne."

He said the Khorne wasn't actually that bad, he'd just gone astray, and he wanted to save him.

At that time Angron was already possessed, staring at the pair of battle axes given to him by the Chaos God in his hands all day long, saying that there was only one chance to restore the Warp to its greatness, and if you can't seize it, then let the Warp Burning Fiercely.

Mordred was surprised to learn about the Gold Ring; looking at the Butcher's Nail on his hand, he almost doubted his own hearing.

"Enough said, I've tasted enough. Horus may be gone, but everyone is Horus. Although we can't kill two birds with one stone and bring back Angron as well."

But don't worry, thanks to that brilliant idea back then, with this nail that's synchronized with Angron's memories, I can also piece together something—

"Forget it, let's disinfect it first. We only have one set of spare parts, and it could easily cause an accident if we don't handle it properly."

The spare parts Mordred mentioned were none other than the spare mechs he had pieced together from scraps when he found Angron.

Eva Unit-01 is the one that currently occupies 95% of Angron, and whose Wetware have been completely taken over by Butcher's Nail; it can be considered the core of Angron.

Unit 2 is the 4% that was filled into Sisyphus, combined with Dahl's remnants, and the little sister built from Sisyphus 1.0.

The last 1% is Unit 3, which Mordred created to show off his skills. It's a useless Ultimate Cat of junk that's a shame to throw away but not worth keeping. Its main purpose is to amuse Angron.

But then again, something is better than nothing. So be it if he becomes a cat. I don't expect Angron to do anything afterward. He can just be a mascot. It's good that he can use the opportunity of forming the Death Guard to form New World Eaters.

Without hesitation, Mordred grabbed his two brothers and left the dimensional rift, returning to the laboratory and successfully finding the Ultimate Cat in the room where Sisyphus was imprisoned.

However, before installing and running the program, Mordred still took the two accessories to the dungeon to check on how the Yellow Skins was recovering and to exorcise the cat.

But when he arrived at the underground palace, Mortarion faltered. He didn't know how to face the Emperor. If a patricide were to occur, he would be doomed.

"Don't worry, the Yellow Skins has dementia now, he's practically skin and bones. You can bully him all you want, he won't even fart."

"Real?"

"Really! You don't trust your Second Brother, but you trust me? If he dares to scold you, I'll go up and kick his nasty leg."

With Guilliman's guarantee, Mortarion felt much more at ease and pushed open the dungeon door. But he didn't see any skeletons at all; instead, he saw a living corpse with flesh growing back, smiling at him.

Their eyes met, Mortarion was nearly scared out of his wits; his legs trembled uncontrollably. But he understood the Emperor's meaning: he was told not to make a sound.

The next second, the flesh and blood vanished, and the Emperor was back to being a skeleton.

[Dad, you're not dead?]

[Shh, if you dare tell anyone, I'll kill you first.]
