Pokémon: Master System.

At such close range, Xia Yu could clearly see its gaping maw dripping foul-smelling saliva, and its red vertical pupils reflecting his own image.

"What kind of reward should I give you?" The three-headed dragon suddenly raised its head, as if asking Xia Yu, or perhaps deep in thought, talking to itself.

Then it suddenly lowered its head, its red dragon eyes radiating a dazzling light.

The three-headed dragon's gaze seemed to have the power to see into people's hearts, making Xia Yu feel that he had no secrets under the three-headed dragon's gaze.

"Oh?" The three-headed dragon seemed to have discovered something interesting, and a surge of immense power rushed towards Xia Yu: "I know what reward I can give you now."

"You actually have so many Dragon-type Pokémon?" Hydreigon's gaze fell on Xia Yu's Poké Ball, and its teasing voice slowly rang out: "It just so happens that I've been alone in this secret realm for too long, and I've forgotten the passage of time. You can leave one of them with me to train, and you can come back to take it away in half a year."

Hearing the voices of the three evil dragons, Xia Yu's face showed surprise.

Leave behind a Dragon-type Pokémon... to train under the guidance of the three Hydreigon before you?

Xia Yu's eyes flashed. This reward was completely beyond his expectations, but he had to admit that it was the best reward among the three levels.

Given the terrifying strength of these three Hydreigon, any Dragon-type Pokémon that trains with them for half a year will definitely experience a surge in power!

To receive personal guidance from a three-headed dragon with near-god-level strength is an incredibly rare and fortunate opportunity.

This also means that Xia Yu will have to be separated from his Pokémon for half a year.

Who should we send?

Xia Yu fell into thought. Among the Dragon-type Pokémon in his hand, aside from Charizard and Sceptile, which have Dragon-type attributes after Mega Evolution.

The remaining six are: Dragapult, Haxorus, Salamence, Noivern, Dragonair, and the yet-to-hatched Duraludon.

Duraludon is definitely out of the question, as it's still an egg. Dragapult and Dragonair are also definitely out of the question.

This is because Xia Yu's Dragapult is a Shiny Pokémon, and also Xia Yu's signature Pokémon.

If Xia Yu stayed in the secret realm, and someone were to break into the third level of the secret realm and see the shiny Dragapult, they would immediately think that Xia Yu had been here. At that time, Xia Yu's shiny Dragapult would not be by his side, and it would be difficult to explain.

The reason why Hakron cannot stay here is also very simple.

Since Dragonair was a Pokémon that Xia Yu had just caught, there wasn't much of an emotional connection between them. If he left it here, Xia Yu might lose Dragonair.

This leaves Xia Yu with only three choices: Haxorus, Salamence, and Noivern.

Xia Yu thought for a moment, and finally focused his gaze on the Noisy Dragon.

Noivern is Xia Yu's highest-potential Pokémon and also his starter Pokémon.

It started with King-level potential, improved to near-Champion level, and then improved to Master level through five silver crowns.

…………

[Speaking of which, let me also explain why Xia Yu used the Silver Crown on Sonic Dragon instead of Iron Warrior or Draco Balto.]

The Silver Crown's ability is to maximize a certain ability. For example, if the maximum individual value (IV) for each ability in the game is 31, the Silver Crown's effect is to maximize that IV to 31.

For creatures like Draco and Iron Warrior, whose inherent aptitude is already at the near-master level, it is likely that their individual values ​​for various abilities are 30 or even 31. Using the Silver Crown on them would not have a significant or even any effect.

The Silver Crown is more effective on Pokémon with lower potential. It raises a Pokémon with an IV of 0 to 31, and it also raises a Pokémon with an IV of 30 to 31. That's why Xia Yu used it on Noivern and Cinderace, which have the lowest potential.

Because only in this way can the improvement in qualifications be maximized.

…………

Noivern is undoubtedly the Pokémon with the highest potential in Xia Yu's possession, and the most suitable Pokémon to train with Hydreigon is naturally the one with the highest potential.

In particular, advancing from the Master level to the Quasi-God level is an insurmountable chasm, much like the difference between mortals and gods. Following it might provide some experience for breakthroughs, preparing one for future breakthroughs to the Quasi-God level.

Therefore, considering all these factors, Noivern is the best choice to stay.

However, this was only Xia Yu's own idea. Ultimately, who should follow the three-headed dragons to cultivate would still have to be consulted with them.

Thinking of this, Xia Yu took out a Poké Ball and released Noivern, Hydreigon, and Salamence.

As soon as the three Pokémon appeared, they immediately saw the terrifying Hydreigon, which looked like a giant dragon. Its immense pressure brought them a great sense of oppression.

Xia Yu looked at the three Pokémon and slowly spoke, explaining the situation to them: "Noivern, Haxorus, Salamence, is any of you willing to stay here and train with Hydreigon for half a year? I will come to pick you up after half a year."

"You have all seen how powerful the three-headed dragon is. If you train with it for half a year, your strength will definitely improve significantly. However, we cannot meet during these six months."

"Only by becoming stronger in solitude."

"You need to be mentally prepared. If anyone wants to stay, you can let me know."

After Xia Yu finished speaking, his gaze fell on the three Pokémon.

The Haxorus shook its head directly, clearly indicating its refusal.

Although it has now evolved from a toothy creature into a Haxorus, it is still as clingy as it was when it was a puppy.

Next was the Bloodwing Wyvern, which also shook its head, clearly unwilling to stay here.

Therefore, Xia Yu could only focus his attention on the Noisy Dragon.

"Sonic Dragon..."

The decision is yours...

"Whether you like it or not, I respect your choice."

"If you're willing, I'll let you stay and come back for you in six months."

"If you're not willing, I'll give up this reward."

"It all depends on you..."

Meeting Xia Yu's gaze, Noisy Dragon's eyes gradually hardened, and then it turned to look at the three-headed dragon in the sky, which was as powerful as a god.

Its enormous size and surging energy inspire awe and make people dare not confront it.

Training alongside such a powerful three-headed dragon?

…………

In the past, the three-headed dragon would have refused without hesitation; it only wanted to stay by Xia Yu's side.

But now, after experiencing so much, Soundwave Dragon has grown a lot. Its thoughts have changed, it considers more things, and it is no longer as carefree as before.

Noisyur now understands the importance of strength better than anyone else.

Previously, it was the weakest of all Xia Yu's Pokémon. It didn't like training, was playful and carefree.

The end result was that it became increasingly marginalized within Xia Yu's team.

This was the first time it had truly grasped the importance of strength.

Especially when it saw Charmander, who joined the team later than it, evolve into Charizard, and Treecko evolve into Sceptile, while it was still just Nombat, it felt a sense of urgency and crisis.

That period was the most agonizing time for it. Unable to help Xia Yu much, it grew increasingly eager for power.

Although Xia Yu's attitude towards it remained unchanged, its mindset subtly shifted when it saw that Charizard and Sceptile could stand on their own.

Although it evolved into Noivern after that, it still couldn't change anything.

By then, it had fallen behind Charizard and Sceptile, becoming the weakest member of the trio.

The situation only improved slightly after Xia Yu used the Silver Crown on it, bringing its aptitude to the Master level.

Only by experiencing the world of the weak can one develop a desire for strength.

He has now realized the importance of power and knows that if he wants to stay by Xia Yu's side forever, he must have great strength.

The Noisy Dragon looked at Xia Yu with an increasingly determined gaze. It had already made its decision, nodded sharply at Xia Yu, and then turned to roar at the three-headed dragon.

Seeing Noivern nod, Xia Yu felt a sense of relief. The little Noibat had finally grown up and had the courage to stand on its own.

But at the same time, he also felt a sense of loss, like watching a child he had raised since childhood venture out on their own, and he couldn't help but feel a little worried.

From the time Nobbat was still an elf egg, he has never been separated from Noivern.

Noivern was Xia Yu's starter Pokémon and the key to his becoming a Dragon-type master.

Even though he knew that letting the Soundwave Dragon train with the Hydreigon was the best option at the moment, Xia Yu was still extremely reluctant to part with it for half a year.

"Sonic Dragon, have you thought it through?" Xia Yu asked, looking at Sonic Dragon.

Noisy Dragon nodded slowly, looking at Xia Yu with a resolute gaze.

"Okay." Xia Yu walked towards the sonic dragon and gently hugged it: "I will definitely come to pick you up in six months. Take good care of yourself."

Noisyboro stretched out its huge wings and hugged Xia Yu. After a brief embrace, Noisyboro resolutely turned around, flapped its wings, and flew towards Hydreigon, disappearing into the clouds.

They both knew that this separation was for a better reunion next time.

"Now... you can go to the final level of the secret realm!" With the voice of Hydreigon rang out, a silver rift appeared in the sky. Xia Yu recalled all his Pokémon and headed to the fourth level of the Dragon Spiral Tower!

…………

The fourth floor of the Dragon Spiral Tower.

"The dazzling sun will eventually dispel the darkness, burn away sin, and all blasphemers will turn to ashes."
