Start as a Silver Dragon and travel to Equestria

"Xingxuan... what are you holding with magic..." Stygian looked at the matte black metal weapon with red muzzle and smoke, a little confused.

"Oh, this is the imitation firearm M4A1 carbine I made myself. It has the characteristics of high range, high rate of fire, and high lethality. Although it may not be as good as the prototype in some aspects, if it is equipped with armor-piercing bullets, I think the Siren at that time would not need to be exiled..."

......

The three siren sisters who were on tour in the human world suddenly shuddered...

"Sonata... Do you feel a chill..." Adachi looked at Sonata sitting in the passenger seat of the small van and wrapped her clothes around her.

"Me too, maybe... going to Canterlot High School to participate in the tour is a mistake? But the rewards for the singing competition are really generous..."

Alia's voice came from the van behind

"Don't worry, when you get there, remember to come down and eat some toast."

......

"Um...are you serious?" Stygian looked at Xingxuan, who looked like an arms fanatic, with some hesitation.

"Hahaha, of course I'm kidding, how is that possible?" Xing Xuan threw the gun to Stygian and replaced the magazine with one filled with rubber bullets.

"Come, try this. It's really better than magic. It doesn't consume physical strength and has lethality. Although it may not work on some magic shields."

"No... No, Luoshu invited me to help manage this place. By the way, have you found anything strange about Luoshu recently?" Stigian declined the gun that Whitebeard Xingxuan pushed at him.

"Um... no." Star Swirl the Bearded looked disappointed that Stygian was not interested in this thing.

But at this time, Gilda, wearing black composite armor, knocked on the door and entered.

"Old Deng! If you continue to recommend something you made that is completely unsafe, I swear I will kick you out of the institute in the next second!" Star Xuan, pointing at the white-bearded man who was loading the magic incendiary bomb, shouted.

"Ha! You little eagle, be more respectful in your tone. Even though you are the one in charge of security here, it doesn't mean you can scold me. As a great magician, I have my own limits."

"Then take a look at what this is?" Gilda looked teasingly, and with a smile on his face, he took out a bill from his armor and shook it in front of Whitebeard Xing Xuan. The long bill almost gave Xing Xuan a myocardial infarction.

"What?! Nearly ten thousand horse bits! Are these things so expensive? Luo Shu never said he would compensate for it."

......

Shining Chijing had a rare holiday, because today was the founding day of the Phantom Empire, and they also got 3 days off, so he decided to come and play with Teacher Luoshu, he hadn't seen him for a long time.

After some inquiries, he found out that Luo Shu had established a research institute, and he estimated that Teacher Luo Shu should be there.

When he was still struggling with how to get into the underground entrance guarded by several griffins, the griffins opened the door for him directly. It seemed that he should be on the whitelist...

After entering the institute, Shimmering Red Crystal looked around curiously. After passing the body search at the security checkpoint on the first floor, Shimmering Red Crystal's long sword and several daggers were left in the prohibited items storage room...

"Um... these things can't be brought in?"

Shining Red Crystal looked at the almost pure white pony in front of him, except for a few blood-red highlights on its mane. The pony was recording the contraband items he brought.

Flashing Chijing glanced at his work badge hanging on his white uniform: Yuqi, security guard, Pegasus...

"Yeah, that's right, even if you are Minister Luo Shu's student, it's not allowed. Okay, let's go, remember to come and get it when you come out later." After Yuqi used his wings to hold the pen to record the things, he left the prohibited items storage room with the flashing red crystal...

When Shimmering Red Crystal walked all the way to the fourth floor, he stopped because he saw something that looked very familiar to him. It was exactly the same as the thing in the "future" reflected by the Harmony Tree...

First there were the lightning feathers, then these strange devices... Things in the future are emerging one by one. Does this mean that the future is real...

So that strange black and red Alicorn...could it be lurking somewhere...

The glittering red crystal stopped the descent to the fifth floor...

"I can't ask Teacher Luoshu for everything... My own future is controlled by myself, maybe I can solve it myself..." Flashing Chijing took a few steps back, but there was still some hesitation in his eyes. However, after struggling for a while, he decided to tell Luoshu about his concerns.

......

Luo Shu, who was formulating new rules and regulations, put down his pen and looked at the closed office door.

"Aren't you coming in yet? Flashing Red Crystal?"

After standing at the door for a long time, Shimmering Red Crystal pushed the door open with magic. He opened his mouth as if he wanted to say something, but the words were stuck in his throat for a while before he could utter a word.

"Good afternoon, Mr. Luo Shu."

"Shining Red Crystal, I can see the worry in your eyes. Do you need my help or answer?"

Luo Shu got down from the chair and walked to the side of the shining red crystal, but his expression was calm and he didn't seem to be concerned.

"Um... it's still about the future, I..." Shimmering Red Crystal remembered that she hadn't asked Luo Shu why there were almost no crystal unicorns before...

"I want to ask... Mr. Luo Shu... why there are almost no crystal unicorns?"

"..., Scarlet should have told you about this. King Sombra was also a Crystal Unicorn before his body shattered, and then he transformed into a Wasteland Shadow Fiend after his body shattered. So the Crystal Unicorn may be a transitional stage of the Wasteland Shadow Fiend...

But, Shining Red Crystal, although you may be... it does not mean that all Wasteland Shadow Demons are bad, or you can go to the extremely cold land north of the Crystal Empire to find the answer."

Luo Shu had said so much, he could not give any more hints, his words only served to correct and assist fate...

Watching Shimmering Red Crystal on the sofa in his office, he was thinking...couldn't think...his brain was down...preparing to practice, and then he called out to Shimmering Red Crystal who was about to leave.

"Shining Red Crystal, wait a moment and don't leave"

"What happened to Teacher Luo Shu?"

"Let me measure your size. We are going to develop a prototype armor soon. You can try it first." Then Luo Shu took out a design drawing with dense markings on it, and those markings...

The more I look at the twinkling red crystal, the worse it looks...

The initial functions and future research directions marked above are exactly the same as the equipment worn by the ponies he saw in the future...

......

In the extremely cold land, a cloaked figure appeared...
