The party continued for another hour. The ones who fainted regained their consciousness and continued partying without any care. It seemed like the leaders flaring their Spirit Powers was something that happened a few times in the past, so they weren't really that surprised anymore.
Panlong and Qianlong talked to him for a while, telling him the story about how they ran the Castle when Ao was sleeping for 10 years. All the time, though, Ao kept silent and maintained her regal figure, not opening her mouth even once unless necessary, like ending the party.
According to Qianlong, Ao didn't talk much unless they talked about important matters, such as what they should do about the future of the dragons or when there was a war conference.
It surprised him when Qianlong mentioned the war conference. But when he thought about it again, dragons lived for a long time. Probably more than a millennia or two. They lived through a time when not all Supernatural races were friendly with each other.
Some were still not friendly, but it was peaceful enough compared to a thousand years ago, or so she said. The one who stopped the war was the strongest as he made contracts with many Mythical Races and made them friendly with each other.
That was why the Ruler was respected and feared. And that was why Qianlong tested him earlier. Not only to know his real intention but also to know his personality. He passed the test with his answer.
After the party, Kai returned to the bedroom, walking through a long corridor with Ao and a few servants who escorted them out. The others also changed location to the great hall in another building to continue their party.
Entering the bedroom, they sat on the bed and Ao spoke.
"That was marvelous, dear husband."
She had a proud smile on her face as Kai turned to her, confused.
"What do you mean?"
"Qianlong is a bit headstrong, and Panlong hates someone without guts. The fact that you challenged them and delivered a satisfying answer made them like you, which is a bit hard to do. That's why it's marvelous, my Dear."
The Dragon King approached him, leaning her head against his shoulder in a loving manner. "You're really the perfect one for this lady."
"Is that so?" Kai replied, a bit happy that he did a good job convincing the two leaders of each faction earlier. "What shall we do next? Is there any plan for today?" He asked, looking at Ao, who was clinging to him.
She was really different when she was outside. The strict Ao looked really cool and unapproachable. Meanwhile, the Ao that he saw right now was cute and really clingy.
Looking up at Kai, Ao had a grin. She then pushed him down on the bed and licked her lips, much to Kai's surprise.
"We do have a plan, dear husband." She said, leaning forward to his ear.
His heart was beating. Scratch the cute; this Dragon King was a cool woman. "What plan?" He asked, a bit anticipating something again.
But while he was excited, thinking she would help him to replenish his Spirit Power again, her answer wasn't what he had expected.
"It's your training." She whispered before backing away, giggling happily. "Did you expect something more? Let's save that one tonight, okay?" She put her index finger on her lips, smiling playfully.
Kai was a bit embarrassed. How could he think something like that when it was clear that she had brought him here to make him stronger? Of course, it was training.
He sucked at controlling his Spirit Power, and Ao was trying to teach him how to make his control better.
"So we start today?" He asked, trying to be as expressionless as possible.
Ao nodded, moving away from his body and lying beside him. "I will be the one who teaches you how to control your Spirit Power and help you replenish it slowly. This Castle has abundant Nature power, so you will fully recover your Spirit Power in a single day."
Right. Unlike in New York, he could feel this place was filled with Nature power. It was even more abundant than the power spot in Japan where Spirit Foxes lived.
Absorbing Nature power in this place would help him recover at a fast speed. However, it would be a bit longer than usual because his Spirit Power reserve grew in size once again. It was even bigger than Amber's now.
He didn't know how big Ao's Spirit Power reserve was because he hadn't fused with her yet. But maybe, it was even bigger than Amber and Ibaraki combined, seeing how Ao lived way longer than both of them and her position as the Dragon King.
Even Qianlong and Panlong, who weren't even Mythical Beasts, had Spirit Power comparable to Amber. The world was vast, and Kai was happy to know that he could still explore it. But at the same time, he also realized that Amber might not be as powerful as he initially thought.
'I need to get stronger.'
Ao noticed the change in Kai's emotion. She raised her body and looked at him. "We can do it slowly, dear husband. We have all the time we need in this world. We will be safe inside this Castle. Slowly, we will build your strength, skill, and knowledge. Qianlong and Panlong will also assist you in your training."
"Both of them are?" He asked, surprised.
"Yes." Ao nodded.
"Qianlong will teach you about Supernatural World knowledge. You can ask anything to her. She's really smart." She boasted proudly as if Qianlong was her own child.
"Then Panlong will teach you about fighting techniques. He's a western fire dragon, and I think he can teach you to control your Phoenix fire and close-quarter combat. And every night, I will teach you about how to control your Spirit Power. I hope you have a lot of energy left, dear husband."
The way she spoke had a hint of hidden meaning. Kai didn't want to think about it and only nodded his head. Obviously, he noticed what that hidden meaning was. The way she said it was enough for him to realize it.
"Well–" He started, raising his body. He looked at Ao with determination. "Let's start right now. What should I do?"
"Just stay right there." Ao replied and crawled behind Kai. She slowly undressed him, only the top, revealing his lean body. His muscle was gone, and he was ashamed.
'I need to train again to regain my lost muscle.'
"Don't worry, dear husband. You're fine the way you are. Don't force yourself."
"Hahaha…" He laughed bitterly. It was like Ao could read his mind. Then she continued.
"You're easy to guess," Ao replied with a small giggle as she put her hands on Kai's back. "Alright. Now concentrate on how I move Spirit Power inside your body. We will do this training daily until you can move it yourself similar to the way I move it. Do you understand, my Dear?"
"Yeah." Kai nodded and sat comfortably. His legs were crossed and his hands were on his lap. This was what people called Lotus Position. He could concentrate better when he sat like this. "I am ready."
