Joining Horus!!!

Using Angron's cells, a batch of cerebrums was cultivated for use in the upcoming surgery.

The surgery began.

Using a local anesthetic from Nuceria, Angron was put into a semi-conscious state, as it was necessary to constantly inquire about the effects.

As expected.

The Butcher's Nails were far more complex on the inside than the outside, with dense black coils wrapped around Angron's brain.

It was as if something was constantly pulsing, with one area completely transformed into the shape of a nail.

Francis inserted a cerebrum next to the nail and asked, "How do you feel? Any other sensations?"

"I want to cry. My adoptive father died by my hand. I still remember the look of despair and helplessness in his eyes... sob sob sob..." Angron began to cry uncontrollably as he spoke.

"It's okay, it's all in the past. They would want you to live well too," Francis comforted him, looking overwhelmed.

"I'm a coward! If I had resisted sooner, this wouldn't have happened! If I had sooner... sob sob sob..." Angron's crying wouldn't stop, and Francis couldn't calm him down no matter how hard he tried.

Only when Francis removed the cerebrum did Angron immediately return to his poker face.

Francis: "Do you still want to cry now?"

Angron: "I can't."

"Very good. If you feel distressed, you can channel it through the third wire on the left."

With that, Francis embedded the cerebrum into the other side and continued to ask, "How does that feel? What is it this time?"

However, this time Angron fell silent.

Francis immediately sensed that something was wrong and quickly said, "Brother Twelve, don't scare me! I didn't accidentally block your speech nerves, did I? I'll remove it right away."

Just as Francis was about to pull it out, a flush spread across Angron's face. "No, I feel great right now. My heart's just been pounding. I think I've fallen in love with that female gladiator!"

Francis: !!!

Huh?

This, this, is this world even allowed for a Primarch to fall in love with someone?

This isn't right!

Francis quickly changed the position again and asked, "How about here?"

"Hahaha~ Let me tell you, I once saw a group of pigs lined up, hahaha, lined up and falling into a ditch, hahaha~"

Francis: ...

"Sigh~ Horus and the others are asking me to overthrow the Imperium and kill the warriors in the Legions who are loyal to the Emperor. Sigh, what should I do? Sigh~"

"This feeling, this feeling is so... so... so... wonderful~"

"Those slave owners deserve to die! They all deserve to die!"

"..."

After extensive experimentation, Francis finally identified the connection points for several common emotions. Next, he began to miniaturize the cerebrums and streamline Angron's brain, leaving only the emotion regulation parts.

Finally, after a week.

Francis compressed all the emotion-regulating nerves into a metal rod the thickness of a finger. He couldn't help but exclaim, "Technology truly changes destiny!"

"Here you go, Brother Twelve! Little magic stick coming through!"

Crackle~

The metal rod was placed directly onto Angron's head, though its shape was a bit strange.

Seeing Francis's odd expression, Angron asked in confusion, "Did it fail?"

"Not at all, it's just the shape that's a bit odd." Francis rubbed his chin, feeling like he'd seen it somewhere before.

Suddenly.

A long-dormant memory resurfaced. Francis gritted his teeth and said, "Try it first. How does it feel?"

The moment it was connected, he felt a wondrous change.

He wanted to laugh, and then he burst out laughing. "Hahaha~ I can laugh now!"

"Hahaha~"

"Hahaha~ Why can't I stop? Hahaha~"

Watching Angron clutch his stomach as he laughed, Francis calmly stroked his chin. "Because, fundamentally, it still relies on the Butcher's Nails. It's just that my device has tricked it now."

"It thinks that the emotion of laughter is anger and slaughter. Everything else is the same; if you don't fight, you'll just laugh harder and harder."

"When the Butcher's Nails react, it will switch to another emotion."

Angron rolled on the ground, tears streaming down his face as he laughed. "Hahaha~ How long will that take, hahaha~"

"It'll probably switch every day or two, usually not too long, as it's just a temporary deception," Francis observed him intently.

"Hahaha~ This is terrible. Hahaha~ I'm going to laugh all day, hahaha~" Angron laughed, pounding the ground.

"Actually, it's not that bad. Now, if you go into combat, you'll lose your joy and become calm," Francis shrugged.

"Right, you mentioned earlier that Horus contacted you, asking you to betray the Imperium with him. What do you think about that?"

"Hahaha~ What do I think? Hahahahaha~ All I want to do now is laugh hahahahaha~" Angron rolled around on the ground.

Francis: "..."

"Actually, there's another way. If I can rule over a great many Orks and then persuade them to launch a Waaagh!, perhaps I can help you take him down directly."

"However, opportunities like that are rare. Sigh, get used to it for now. Come find me when you've calmed down." With that, Francis walked towards the next room.

Mainly, he couldn't hold it in anymore. Angron wearing that thing was like a beefy Teletubby!

Meanwhile, Angron ran outside, still laughing maniacally. "Hahaha~ I'm going to find the World Eaters. Hahaha~"

The World Eaters, who had been confronting the Space Wolves, suddenly heard hearty laughter.

On this day, the World Eaters finally felt the fist of their Primarch's love; he was genuinely laughing maniacally.

Angron was happy, and the World Eaters were happy too!

Only the Space Wolves warriors were bewildered, muttering to themselves.

"Huh? When did the Primarch of the World Eaters Legion become so friendly?"

"I don't know. I don't know. Anyway, I think they're enjoying being beaten up. Maybe it's a special kink..."

"Let's go see the Wolf King. The Warmaster sent orders three days ago, telling us to bring the Soul Drinkers and their Primarch to him."

"Yeah, we can't wait any longer! The Warmaster is already urging us on, heading to Istvaan III."

Saying this, they walked towards the medical bay where Leman Russ was.

"So, Horus is already contacting other Primarchs to rebel, is that it?" Leman Russ's eyes were gloomy and uncertain. He could dismiss it if one person said it.

He could still dismiss it if two people said it, but this was already three.

Leman Russ had no choice but to believe!

"Yes, if I'm not mistaken, they're about to strike against their own people!" Francis continued.

"Then what do you think we should do? Tell Father?"

Hearing this, Francis gave a bitter smile. "Me, plus Little Horse who almost caused a big mistake, plus those he already dislikes..."

Suddenly.

Francis trembled. The Emperor couldn't possibly not know about the Primarchs' rebellion.

Since he knew, yet he didn't intervene, it meant we couldn't count on his help!

Realizing this, Francis suddenly understood.

He said to Leman Russ with a solemn expression, "Why don't I go with Angron and defect to Horus!!!"

Leman Russ's eyes widened. "This! This! This!"
