My little pony:Adventure of Seresia

"Huff... huff..." The rapid, heavy breaths filled the quiet room on that early morning, standing out sharply. Spike had just woken up from a nightmare, and beads of sweat still lingered on his forehead. In his dream, he was running through a raging snowstorm, holding the Crystal Heart in his claws, desperately trying to place it back into the device. But just as he was about to succeed, the Crystal Heart suddenly melted, turning into a puddle of pink liquid that slipped through his fingers. Spike panicked, trying to fix everything, but it was futile. All around him, the snow and ice had frozen everything solid, but the liquid was still flowing rapidly, unaffected by the cold. The howling winds, mixed with snow, seemed to laugh at him as they echoed in his ears. When everything faded, Spike found himself surrounded by ice sculptures of varying sizes—Twilight, Shining Armor, Cadance, and other residents he knew, all permanently sealed inside. He even saw his own image, though it was without wings.

"What a horrible dream..." Spike rubbed his face with his claws, taking a while to snap out of his shock. As he took in his surroundings, he realized he was back in Canterlot. But... had he been unconscious for days? He only remembered the last thing before passing out—hiding with the crystal residents in the ruins under the stage, trying to keep warm with his dragon fire. Speaking of which, Spike felt incredibly thirsty. Spotting a cup of water on the bedside table, he grabbed it and drank it all in one go. But it wasn’t nearly enough to quench his thirst. It felt like he could drain an entire pool.

"Knock knock knock!!" As Spike was getting more water, a sudden, sharp knock on the door rang out, coinciding with the sound of the water bubbling in his cup. He stared at the cup, trying to figure out why it was making such a strange noise, only realizing what was happening when the second knock came.

"Who is it? I'm coming, I'm coming, stop knocking." Spike hurriedly opened the door. The first thing he saw was a familiar eastern-style outfit, but when he looked up, it was a changeling. Taking advantage of Spike’s stunned moment, the changeling quickly seized control of the door, turning back to look outside. After ensuring no pony was chasing them, it slammed the door shut and locked it. Spike, feeling suspicious, backed away. He couldn’t remember the last time he saw a changeling with black skin, and this changeling... had it grown taller and bigger? Spike’s curiosity stirred, and he couldn’t help but wonder: who was this changeling, dressed like one of Meng Yu's personal escorts?

"Who are you...?"

"No time to explain, Spike!! I need your help!! Princess Twilight is in danger!!!" Without letting Spike ask anything, the changeling rushed up to him, speaking in a hurried tone and addressing him by name. It even placed a hoof on his shoulder.

"Wait, wait, hold on! First, tell me who you are! And what do you mean, 'Twilight is in danger'?" Spike was confused, still reeling from the nightmare, now faced with a changeling, and hearing that Twilight was in danger. He had to wonder if this was another dream within a dream. After pinching himself to make sure this wasn’t just another nightmare, he tried to calm the changeling down, hoping to extract more useful information.

"I’m... Meng Yu’s personal escort, Jin Yun! I’ve been turned into this by that guy who looks like Jin Yang using magic! ...The chancellor is probably a fake!! We need to move immediately!!"

"Wait... how do I know you’re really Jin Yun, ambassador's personal escort?" Spike asked. Jin Yun clearly didn’t want to waste any more time explaining. Without responding, she grabbed him and pulled him toward the door. Spike instinctively resisted, gripping the doorframe tightly with his claws. While he still didn’t understand the full situation, the changeling’s actions were far from earning his trust.

"It’s here!!! The royal advisor is in danger!!!" Just then, a group of soldiers, twice the number of the previous ones, appeared, and without saying a word, they began attacking Jin Yun. Even though they had the advantage in numbers, the soldiers were quickly disarmed and knocked out one by one, with Spike watching in awe.

"Whoa... you really are Jin Yun..." After witnessing her incredible fighting skills back in the Crystal Empire, Spike finally believed that this changeling was indeed Jin Yun. But how could all of this be happening? Could it be that all these eastern ponies were actually changelings in disguise? As Spike looked at the soldiers groaning on the floor, he couldn’t help but feel some sympathy for them. While checking their bodies, Spike voiced the biggest question in his mind, only to receive a vague answer.

"I don’t have time to explain!! We need to warn the other princesses and lock down the castle, to prevent those impostors from escaping!" Jin Yun spoke urgently, her anxiety clear. If the chancellor encounters any danger, not only would she disgrace herself before the emperor, but it would also shame her entire master's homegate. And right now, Spike was the only dragon she trusted, so she needed his help. But why had she chosen to trust Spike over the other princesses? Maybe it was because he was a dragon.

"Whoa!! Don’t rush so much!! I can walk on my own!!" Jin Yun, still panicked, didn’t consider Spike’s feelings and dragged him out of the room, heading straight for the display hall. Only after repeated requests did she finally let him go, and as they ran, she explained her suspicions.

"If everything is as you say, then we should be going to Princess Celestia and Luna for help right now!" After understanding the situation, Spike suddenly stopped, and Jin Yun, looking both anxious and confused, waited for him to speak.

"But!!... do you really think..."

"Trust me, we can’t handle them on our own. We need more help!!" Seeing that Jin Yun still had doubts, Spike insisted. Honestly, he didn’t understand why Jin Yun was so opposed to the alicorns.

"Alright..." Under Spike’s determined gaze, Jin Yun reluctantly agreed. "Get on my back, we don’t have time to run to the dining hall."

"What are you going to do?" Spike climbed onto Jin Yun’s back, still not understanding the plan.

"We’ll use teleportation."

"Teleport...?!" As soon as Spike heard the word "teleport," he instinctively tightened his arms around Jin Yun’s neck. The words had barely left his mouth when a bright flash of light enveloped them. The next moment, they appeared in the dining hall, startling Princess Celestia and Luna, who were still having their meal.

"It’s that changeling!!" Standing beside Jin Yun and Spike was one of the soldiers who had been knocked out earlier. He had just reported the situation to the princesses. Seeing the changeling, he stepped back in fear, but with the big princess by his side, he gathered his courage. After a brief hesitation, he charged forward, signaling the other soldiers to try and capture Jin Yun. Of course, all their attempts were in vain as they were swiftly knocked out once again.

"Careful!!" Spike, who had been thrown to the side, saw the magical energy building up around Princess Celestia’s horn. A chill ran through him—if that magic hit, it could be disastrous. But Jin Yun was fast, and she noticed the danger. After knocking down the last soldier, she turned swiftly, using the momentum to make her cloak flare up. She ducked down, hiding completely beneath her cloak. When the magical blast struck her cloak, it ricocheted, much like a ball hitting a net at an angle, and flew off in a different direction, leaving a deep scar on the wall.

"Princess Celestia!! Please wait!! She’s not a changeling!! She’s Meng Yu’s escort, Jin Yun!!"
