Yveltal, flying at high speed in the sky, brought Gui Ling to the marked ruins. On the way, Yveltal noticed Gui Ling's serious expression and was a little puzzled.

Gui Ling put on a black cloak and began to sharpen his skills, looking ahead with sharp eyes.

"......... (What's wrong? This is the first time I've seen you like this.)"

"There's probably going to be a tough battle ahead. Are you scared?"

"......... (What do you think?)"

"Hmph, I thought so too. This time, we not only have to face a powerful organization, but also a Mega Evolved Rayquaza. Are you ready?"

Yveltal was stunned for a moment, and after a long period of thought, he also showed a serious expression.

"......... (Although this trip is a bit dangerous... I am willing to go with you.)"

"If we can't win, we run. I don't want any of us to get hurt."

Gui Ling gently stroked Yveltal's back, trying to help him relax.

"......... (How confident are you?)"

"If all of us Mega Evolve, we have seven-tenths of a chance. The main thing is to reap the benefits of others' struggles. We must not act too hastily."

.........

At this moment, at the top of a ruin, there were two stone pillars. Steven, Fleur-de-lis, Manon, and Alan arrived and began to investigate with two Pokédexes.

Finally, Alan and Steven touched the two stone pillars with their respective Key ites. The next second, a colorful ladder to a sky island appeared, and everyone, with excited hearts, slowly walked forward and up.

"I'm truly impressed, Mr. Fleur-de-lis. If it weren't for you, I'd probably still be digging holes here."

"Not at all, I should be thanking you."

"Thank you too, Alan. If it weren't for you, this path wouldn't have been created."

"To be thanked by the Champion, you're really something!"

"Then let's go."

An island floated in the sky, with countless ancient ruins on it, and the degree of damage was extremely great; it was impossible to discern what the previous buildings looked like.

"The giant stone... should be here."

Steven and his group arrived at the central ruin and began searching all around. Then, on the altar in the middle, Steven translated the ancient script and finally came to a conclusion.

"On these two altars, offer different keys."

"No mistake, the giant stone is here! Alan, you go to the altar on the opposite side."

When the two again placed their Key ites, the mechanism in the middle lit up with colorful light, and as the mechanism moved, the giant stone was slowly lifted out.

"We found it, the legendary giant stone!"

"The origin of Mega Evolution..."

"The Key ite also reacted greatly."

Fleur-de-lis picked up his phone and made a call. A few minutes later, a huge airplane flew over, and many staff members began to test the giant stone's data with instruments.

"What is this doing?"

"First, an analysis of the composition, because this is a very valuable discovery."

But just as the analysis wave hit the giant stone, the giant stone began to emit strong energy and started to vibrate.

"The energy of this light... is the same wavelength as a Mega ite! And its heat far exceeds that of a Mega ite!"

But just as the detection was underway, the sky began to be covered with dark clouds, and several bolts of lightning struck down.

Slowly, a dragon's roar came from the dark clouds.

"Something's coming!"

As Alan's words fell, a Rayquaza emerged from the dark clouds and began to hover above the giant stone.

"Representative! The internal pressure of the giant stone is higher than expected!"

With Rayquaza's roar, golden Mega Evolution light began to burst from its body.

As the light enveloped Rayquaza, the next second, Rayquaza completed its Mega Evolution, and the giant stone also began to emit intense energy.

"Rayquaza Mega Evolved?!"

"How is that possible...?"

"But it definitely happened!"

With a dragon's roar from Rayquaza, it began to charge up a Dragon Pulse. Alan saw the light and immediately told everyone to avoid it. A great battle was about to break out.

After flying for some time, Yveltal finally arrived at the location. Gui Ling saw that the battle had entered a white-hot stage, exchanged glances with Yveltal, and began Mega Evolving in advance.

Gui Ling jumped from Yveltal to Noivern, then flew rapidly to the battlefield.

Just as Rayquaza was about to unleash Draco Meteor to destroy the giant stone, Yveltal directly fired a Hyper Beam, forcefully dispelling Rayquaza's attack.

Under the shocked gaze of Fleur-de-lis and his group, Gui Ling descended from the sky riding Noivern. Gui Ling observed the situation and found that the current situation was very favorable to him.

Not only were the staff either dead or injured, but Metagross and Charizard also suffered significant damage. The current situation was definitely the best time.

"Come out! Everyone!"

Gui Ling summoned all his Pokémon and began their Mega Evolution.

What attracted Steven the most among them was definitely Mega Diancie. Upon seeing Diancie, Steven felt that the giant stone was no longer appealing; he forgot everything else and stared intently at Little Princess Diancie.

Diancie noticed Steven's gaze and looked back. Seeing Steven's infatuated eyes, she thought for a moment and still warmly greeted him. Just waving a hand with a smile completely captivated Steven.

Metagross, seeing Steven in his current state, could only carry him away sheepishly.

Fleur-de-lis, looking at the mostly Mega Evolved Pokémon in front of him, was somewhat surprised but showed no excessive emotion. However, he did have a desire to recruit Gui Ling.

Mega Rayquaza roared at the Mega Yveltal in front of it, as if declaring its sovereignty, but Yveltal said nothing and directly fired a Death Wing.

Yveltal had been looking forward to this battle for too long. He knew that under normal circumstances, he would definitely not be able to defeat this guy, but he had his most trusted family behind him.

Indeed, after Rayquaza dodged Death Wing, a Dragon Pulse was fired, but it was blocked by Diancie's Sacred Diamond.

Immediately following, Will-O-Wisp, Gunk Shot, Moonblast, Boomburst, Water Shuriken, Wood Horn, Razor Leaf, Psycho Cut, and Dark Void all surged towards Rayquaza.

Although Rayquaza was incredibly fast, it still took some damage from the dense attacks. It was even hit by Dark Void and paused for a moment, but quickly recovered. The next second, Yveltal's Hyper Beam directly hit him and blasted him away.

Rayquaza: Group attack, huh? Fine, fine, fine! If you have the guts, fight me one-on-one!

Rayquaza roared in anger and used its Dragon-type ultimate move, Draco Meteor, but it was completely blocked by Diancie's Diamond Storm. However, this also left Diancie almost exhausted. Fortunately, the stone given by Xerneas had a strong Fairy aura, which immediately restored Diancie's stamina.

Seeing that its attack was useless, Rayquaza's body began to glow with green energy. This was its exclusive ultimate move, Dragon Ascent, but this skill had a drawback...

"The drawback is that you can only attack forward with this thing! Yveltal! Kyogre! Use Death Wing and Psybeam from the sides!"

As Gui Ling tightly gripped the Fairy stone, a strong Fairy aura enveloped Diancie, creating a huge diamond barrier. Gengar and the others also used Protect, condensing barriers with their own energy, hoping to lessen the impact of Dragon Ascent.

But everyone's Protect was immediately broken through. Only Diancie's Sacred Diamond blocked this attack, but Dragon Ascent did not stop, relentlessly destroying the Sacred Diamond.

Yveltal and Kyogre struck Rayquaza from the sides, and the Sacred Diamond also began to show cracks. Just as the Sacred Diamond was about to shatter, Rayquaza finally couldn't withstand the petrification effect of Death Wing and turned into stone.

Although Yveltal was weaker than Rayquaza in every aspect, the petrification effect of Death Wing was too overpowered. Even if it could be resisted, its life force would still be fed back to Yveltal.

What's more, it also took a Psybeam hit, and being quadruple weak to Ice is no joke.

Watching Rayquaza, now turned to stone, fall to the ground, everyone finally breathed a sigh of relief. Diancie also finally couldn't hold on and dispelled her Mega Evolution. Gui Ling quickly pulled Diancie into his arms.

“You’ve worked hard, Little Princess. Get some good rest.”

“Gardevoir~”

After Gui Ling handed Diancie to Gardevoir, he also patted Yveltal and Kyogre’s heads.

“Kyogre, you were a great help. Your Psybeam was excellent.”

“Woo~”

“Thank you, old friend.”

“………… (Never mind, let’s just think about how to deal with this giant stone, and this Rayquaza, are you going to catch him?)”

“Not for now. This Rayquaza isn’t my target.”

Gengar and the others also rushed over to encourage him, and Gui Ling happily embraced everyone. At this moment, Fleur-de-lis calmly watched everything and slowly walked over.

“The Trainer of Yveltal, that rumor was indeed true, but now the rumor needs to be changed, because this Trainer also has a Lord of the Ocean.”

Gui Ling glanced at Fleur-de-lis and ignored him, instead slowly walking to the front of the giant stone, revealing a villainous smile.

“I finally got it. With this, Kyogre can perform Primal Reversion, right?”

Gui Ling nodded towards Kyogre. Because there was no water, Kyogre could only look at the giant stone from the ground, unable to reach it.

Yveltal quickly grabbed the giant stone and slowly flew above Kyogre, signaling it to open its mouth.

Seeing the situation, Fleur-de-lis panicked and quickly tried to stop Gui Ling.

“Wait a moment! Mr. Gui Ling!”

“What’s wrong?”

Gui Ling glared fiercely at Fleur-de-lis, crossing his arms and confronting the ‘Golden-Maned Lion King’ in front of him.

“We discovered this giant stone first, please give me some face. Our Team Flare needs this giant stone. If you want Kyogre to undergo Primal Reversion, we can help you!”

Gui Ling sneered, stepping on the petrified Rayquaza and pointing at the giant stone behind him.

“That thing is my prey, and this Rayquaza is too. I don’t want anyone stealing my prey, understood?”

Fleur-de-lis tried to negotiate further, but was immediately outlined by Gardevoir and Gengar’s Shadow Sneak. Alan stood in front of Fleur-de-lis at this moment, wanting to command Charizard to attack again.

“Yo~ Isn’t this Alan, who wants to become the strongest?”

“You know me?”

“I’m too lazy to know you. You don’t seriously think Fleur-de-lis is taking this giant stone for something legitimate, do you?”

Fleur-de-lis flinched at this remark, somewhat surprised by Gui Ling’s words.

“Only a fool like you would believe what Fleur-de-lis says. Fleur-de-lis, don’t think I don’t know your scheme. I advise you to drop it. Otherwise… you wouldn’t want to experience the power of Death Wing, would you?”

Gui Ling was too lazy to waste words and snapped his fingers. As Kyogre swallowed the giant stone, its body was immediately enveloped in colorful light.

In the light, Kyogre’s skin began to crack. Primal Reversion, unlike Mega Evolution, doesn’t change one’s appearance, but rather allows one to return to their most powerful state.

The sky began to pour with rain, and terrifying water elements began to gather around, covering the entire Kalos region.

The energy brought by the giant stone exceeded imagination. Kyogre was originally similar in size to Yveltal, but in the light, it began to grow larger and larger. When the light dissipated, Primal Kyogre appeared before everyone.

However, this Primal Kyogre’s size was ridiculously huge. This was the first time Gui Ling had seen such a large Kyogre. He remembered that although Kyogre was large, it shouldn’t be this big, right?

Its size was almost larger than this floating giant island, at least more than ten times its previous size.

“Is this reasonable? It shouldn't be this big, right?”

In just half a minute, the ground already had nearly ankle-deep water. Gui Ling, noticing the situation, quickly told Kyogre to stop.

Kyogre obediently absorbed the surrounding water elements, and the sky returned to its former clear state.

“Such a good boy.”

Kyogre flew over and rubbed Gui Ling’s hand, which made Gui Ling very satisfied.

Even though Kyogre gained immense power, it was still the same child who loved to cling to everyone.

“But your size seems a bit too large, a bit abnormal. Let’s take you to Professor Platane.”

Gui Ling nodded towards Yveltal. Yveltal spat out life force from its mouth into the petrified Rayquaza. The next second, Rayquaza returned to normal and soared into the sky again.

After recovering, Rayquaza shook its head, wanting to attack again, but felt the sky was dark.?

Looking up, it fell into contemplation, seeing Kyogre, who was nearly ten times larger than itself.

“???” Translation: (Is my second brother this big? Am I still not awake?)

Rayquaza shook its head, deciding not to bother with it and directly launched a Hyper Beam. As a result, Kyogre only felt it like a tickle and suffered no damage.

This left Rayquaza even more confused.

“???” Translation: (No? Are you my second brother?)

“Woo—?”

“???” Translation: (You don’t know me? You wouldn’t happen to be the ancestor of my second brother’s ancestor, would you? This size is ridiculous…)

Kyogre clearly felt a bit impatient, opened its mouth, and began to condense Psybeam. In Rayquaza’s shocked gaze, it froze him into an ice pop again.

“Alright, Kyogre, stop playing. Let’s go back.”

After Kyogre unfroze Rayquaza, Gui Ling came in front of Rayquaza and raised an eyebrow, looking at him.

“Are you convinced?”

Rayquaza roared, clearly unconvinced.

“Not convinced? Hold it in! You’re not my target. I’m taking the giant stone, alright? Rather than letting you destroy it, it’s better for me to have it.”

Rayquaza was about to retort, but seeing Kyogre and Yveltal beginning to condense Psybeam and Death Wing, it fell into contemplation again. The next second, it immediately flew away while Gui Ling wasn’t paying attention.

Rayquaza: Oh my god! I met something ominous today!

Gui Ling recalled everyone into their Poké Balls, leaving only Yveltal.

Yveltal also canceled Mega Evolution and lowered itself, allowing Gui Ling to jump on.

“Mr. Gui Ling.”

Fleur-de-lis quietly looked at Gui Ling on Yveltal’s back and said coldly.

“I, Fleur-de-lis, will remember what happened today.”

“I advise you not to remember. If you dare to provoke me, your Team Flare will all suffer.”

Yveltal flapped its wings, carrying Gui Ling into the sky. The air current from its flapping wings directly blew Fleur-de-lis and Alan onto the stones, showing no respect to either of them.

If Gui Ling hadn’t been afraid that his appearance might cause a spacetime distortion, he would have turned both of them into stone statues right now.

…………

“………… (Where to go?)”

“Looking at the time, the Celebration of the Covenant Tree should be here. Let’s go check it out.”

“………… (Why didn’t you catch that Rayquaza? He’s also a Legendary Pokémon!)”

“He’s not my target. My target is that Black Rayquaza who fought seven!”

“………… (Black Rayquaza?)”

“It’s a Shinny, who single-handedly held off seven Legendary Pokémon. Although he ultimately lost, his power was evident.”

“………… (You’re getting a bit ahead of yourself, aren’t you? If you want something that can fight seven, wouldn’t you have to defeat him first? Do you think we can beat him?)”

“Let’s try. If it really doesn’t work, we can just come back and catch that Rayquaza from before~”

“………… (Sigh, you guy…)”

“In the Pokémon world timeline, there seems to be only one giant stone. Here, the author changed the number of giant stones.”

“The author also couldn’t think of a way to make Kyogre undergo Primal Reversion…”

“And then there’s Kyogre’s combat power. Perhaps everyone will feel that this is an epic buff for Kyogre. I will adjust it later, so please look forward to the future plot.”

Oh my god! Thank you to Fu Fu’s Salary Card for the Great God certification! Big brother, I wish you ten consecutive draws with five golds, and no off-banner for Furina!!!
