Start as a Silver Dragon and travel to Equestria

As the controlled Ferris transformed into the World Devourer roared

The surrounding ponies and changelings scattered, while the former Royal Guards cast attack spells and manipulated the weapons on the field...

The other ponies who came to participate in the selection also reacted and prepared to fight the big monster.

Twilight Sparkle and the others were frightened by the appearance of this monster, while Fluttershy hid behind Applejack and trembled. The creature's rotting flesh and scales, twisting limbs, and eyeballs all over its body were truly terrifying.

"What...is that?! What happened to Ferris?!" Twilight Sparkle didn't understand. She had never seen such a twisted thing before, but she saw that it was trying to hurt other ponies.

Twilight Sparkle flew up and scolded Ferris, trying to wake him up, but a corrosive acid shot out from the giant eye and attacked Twilight Sparkle

After Twilight Sparkle dodged sideways, she looked at the grass behind her that was splashed by acid and quickly started smoking and burning.

"Oh... Oops, what strange thing is coming again, a chaotic creature?" Twilight Sparkle realized the severity of the current situation and released a burst of magic attack towards Ferris...

......

Canterlot Castle

"Original Sin? Did you notice it? A huge magical fluctuation?" The Princess of the Universe looked at the Original Sin who was supervising her in establishing the new department. Scarlet was already buried by other miscellaneous documents.

"I've noticed it. I have to go check it out. Scarlet, please stay here and behave yourself, okay?" Original Sin said this without blushing or beating his heart, because he is now a conscious being and has no heart.

Then he touched the scarlet head buried in the documents and smiled playfully.

"Scarlet~ But it's been a while since I last saw you, right? It seems like we really need to find an opportunity to catch up."

Scarlet shuddered as she looked at Original Sin. This guy...she had to find a chance to stay with Luna to ensure her safety.

"Oh, by the way, Princess Celestial, what do you say about letting Twilight Sparkle and the others solve this problem?"

"Okay, but I'm going to see how difficult the trouble is before I make a decision."

......

As the unicorn's magic focused, the giant worm that Ferris transformed into was split into two sections, but this obviously had no effect on Ferris. This was also due to the fact that the original sin changed Ferris's transformation. Ferris's main body only turned into the head of the World Devourer, while the body and other parts were all evolved by magic.

"Wait...what..." Rainbow Dash was stunned, because the broken body seemed to have grown a new head. The feeling of sadness for Ferris disappeared immediately, and she was frightened instead.

"Rainbow Dash! Get out of the way!" The severed body rushed towards Rainbow Dash, but it was too late for Twilight Sparkle to use teleportation magic.

At this moment, a yellow lightning bolt hit Rainbow Dash, knocking her away and avoiding the attack...

"what!"

Twilight Sparkle's attack magic repelled the restless back half of the body.

The front half of the body that was suspended in the air began to descend, and it turned its head to aim downward, at the group of unicorns that had just gathered together to release magic lasers!

"Enough!!!" The voice of the Princess of the Universe resounded through the sky, and the two worms were frozen. Then the Original Sin appeared, and its consciousness turned into a huge black mist that enveloped the two huge worms...

Then Original Sin took back the magic power, naturally freed Ferris, and then looked at the ponies and changelings below, most of whom were injured.

"Original Sin, do you know what this is? I have never seen this thing before." The Princess of the Universe flew to the side of the Original Sin who was holding Ferris.

"It should be the same as the blood mist situation last time. Because of the existence of Luoshu, some uncontrollable factors have appeared."

......

Luo Shu, who was strolling on the street with Luna in the Crystal Empire, felt as if he had been blamed by a dragon.

He was planning to strengthen the Crystal Empire's Crystal Heart, or get some protection.

I don't know what Princess Cadence and Crystal Pony were thinking. They would put such a heavy weapon to maintain national security and resist foreign enemies there openly without any protective measures or guards.

"Luo Shu... So you're leaving tomorrow? Can you tell me about that world?" Luna, who was originally observing the living conditions of the Crystal Ponies, suddenly asked

"Yes, we're leaving tomorrow. As for that world...Luna, are you sure you want to listen?" Luo Shu hesitated for a moment, and Luna nodded resolutely.

"Sure, learning something new about the parallel world would be good for me as a ruler."

"......, well, in that world, there was a war between Zebra Country and Equestria, and you know, during wars, technology evolves most rapidly, so I plan to go there to get some technology that's suitable for ponies, and absorb some of their good political policies, as well as the origins of wars and so on..." As Luo Shu was chatting, he changed the topic to why he wanted to go to that world.

And Luna also listened with great interest, and didn't seem to notice anything wrong...

...

"Oh, Luo Shu, Luna, you finally came to the Crystal Empire"

Princess Yinyun was waiting for Luoshu and Luna to arrive in front of the crystal heart. Luna had told Yinyun in advance that Luoshu was coming to help her strengthen the crystal heart.

"Actually, I think the Crystal Heart only needs the love in the hearts of the Crystal Ponies right now."

"The current crystal heart can only resist the wind and snow. Aren't you worried that the Black Crystal King will make a comeback? Or other evil creatures will invade? And it is placed in such an obvious place, without even any protection..."

"It seems... it is true, so what are you going to do?"

Luo Shu stared at the rapidly spinning crystal heart and grabbed it with his claws. The light on the two crystal spikes that fixed the crystal heart and conducted magic power receded, and the light on the snowflake-shaped radial patterns on the ground also quickly receded.

The surrounding crystal ponies were startled, and a blizzard in the distance began to invade the Crystal Empire...

"Luo Shu! What are you doing? Put it back!" Princess Yinyun was frightened by Luo Shu's behavior, but Luna believed that Luo Shu would not do anything ridiculous. This might just be a warning to Princess Yinyun for her negligence in defense.

"Princess Yinyun, please use magic to protect the country first. How can I strengthen and carve the magic circle if I don't take it down?" Luo Shu said slowly, and then he looked at the huge crystal heart in his claws calmly.

Princess Yinyun looked at the blizzard that was gradually eroding the border in the distance, glanced back at the leisurely Luo Shu and the calm Luna, and had to cast a spell.

The light on Princess Yinyun's horn became brighter and brighter, and then a huge magic laser was fired into the sky, and then exploded in the sky. It was as if a large net was descending from the sky, and a huge light blue transparent magic shield enveloped the Crystal Empire...

Luo Shu's slow and angry voice sounded

"Yinyun, the Crystal Empire has no border defenses, and there are only guards in the castle? Right? Then creatures with ulterior motives can easily sneak in, and at night your defenses are lax. Isn't it obvious that you are handing over the Crystal Heart to the enemy?

And now Equestria is also reforming, and when Shining Armor returns soon, he will retrain a group of Crystal Ponies..."

Luo Shu even spoke these words for two and a half minutes, and only then did he slowly analyze the crystal heart...

Princess Yinyun, who was maintaining the magic shield, also nodded. This was indeed a problem...
