"Where is Nathan?" Sera asked while looking around.
Selena glanced at her mysteriously, as though something bothered her mind. Ultimately, she said, "He is in the bedroom, absorbing some cores. Unlike us, he needs more cores to have the same amount of Ena as us.
"That's why this trip is for him to have the time to swallow those cores.
"It's quite stressful mentally and physically, so absorbing it here will help a bit. The school is pretty chaotic after all."
"Fair enough." Sera looked surprised that Selena gave all that information. She soon smiled and gently pushed Selena from behind. "Now, now. Selena. Why don't we train? I have heard that the sea can be used to train our bodies. Let's do it, shall we?"
Selena looked down, falling into deep thought. She ended up sighing. "Sure. Let's do it."
Sera smiled and led her to the beach.
As Selena said, the trip was made for them to increase their Ena. But because of his absorption rate, Nathan had to spend more time to absorb the cores.
On the other hand, Selena and Sera had more time to train and absorbed the cores during the night.
After a few days, Nathan finally got a visitor.
It was Evelyn. She brought 20 mature class cores with her and dropped them on the bed. "These are half the amount I've promised. Other than the cores you will get from the negotiation with Sullivan, I will give you the rest in two to three weeks."
"Woah." Nathan looked surprised. "You really give it to me?"
"Of course. I don't plan to take back my promise." Evelyn glanced at the numerous cores scattered in the room. She couldn't help but ask, "It seems you're going to summon your fourth familiar. Do you have any idea of what you want as your fourth familiar?"
"I have been thinking about familiars with specific characteristics such as the one ruling over the sky, living inside the water, amphibious, and rare terrains like swamps. I can think of other possibilities, but I think I want a familiar that is versatile with my current situation."
"Versatile with your current situation, huh? And do you understand the situation you're currently in?"
"Yes. I don't know how much they prioritize me, but I am certainly targeted by this secret organization. As a result, I need fighting power that is not only unique but also powerful. This way, I can surprise the enemy.
"It should be an escape artist and have an ability that can extract some information," explained Nathan.
"You sound so greedy. Is there even a familiar that versatile? I have never heard about it." Evelyn frowned.
"The thing is… there is one familiar that can match all my criteria." Nathan smirked.
Evelyn crossed her arms. "Heh…"
Evelyn shrugged. "Nothing. The saintess' Valkyrie as well as the other two familiars from that vampire girl are your doing, right?"
"I don't intend to hide it anyway. It's the knowledge from my beasts." Nathan rolled his eyes. "It's probably because they are beasts that they have different experiences, which allows me to gain a lot of knowledge about other familiars.
"In the past, people who summoned their familiars knew nothing about them until they summoned them and studied about them, right?
"This is the same. Of course, I don't have any intention of telling them about weak familiars."
Evelyn paused for a moment. "You should know my abilities, right?"
"Yes. What do you think I should summon for my new familiar?"
Nathan looked down, falling into deep thought. 'Is there a God of Space or Gravity? Since it's quite rare with the terms of gravity, I should think about the God of Space…
'Hmm. I don't know if there is even a God of Space… at least directly linked to the space element. What about fantasy races? There are simply too many races that I can't think of anything right now.
'Still, if it's Evelyn, she should have a divine being. If only it were like a powerful god or goddess… I could recommend her the Goddess of Night, Nyx.
'No. I think it's more suitable for Selena since vampires and Lilitu are the creatures of the night.'
Nathan sighed. "Sorry. I can't think of anything. Maybe I will ask them about it later."
She squinted her eyes, noticing that Nathan didn't call them right away, even though he was able to do so.
However, she didn't press him. She simply took out a piece of paper. "Anyway, this is the list about the suspected students from the 2nd and 3rd academies. You can use this during the negotiation and see what mission will be suitable for you."
"Understood. I'll also tell you how many mature class cores I get from the sword saint later."
Evelyn nodded. "Tell me when you need the alien. I will send them directly to your room in the academy."
Evelyn turned around and disappeared into thin air.
Nathan sighed again. "It's been a week. I guess I should return to the academy briefly. Besides, Master is about to come here, so I might as well invite them. I guess I should tell Selena and Sera. This is a perfect time for them to get to know each other. I hope they don't fight without me around."
With that thought in mind, he headed outside, finding Selena and Sera training on the beach.
Selena seemed to be correcting Sera's form and position as if teaching her their fighting style so that there wouldn't be any problem if they needed to fight together.
The scene put a smile on his face as his worries disappeared.
Both Selena and Sera noticed him and immediately came to him.
"What are you doing? Are you done with the cores? Or are you too tired?" Selena asked while placing her hand on his forehead to check his temperature.
"No, I'm fine. I'm thinking about returning to the academy for a day. I need to negotiate with Sullivan, especially regarding our next mission."
"Then, I will accompany you." Selena wanted to enter as if planning to pack her luggage, but Nathan stopped her.
"No. I will go alone this time."
Selena looked shocked while Sera surprisingly hugged Selena's arm while coquettishly asking, "It's fine, isn't it? We should continue our training, right?"
Selena looked at her for a while before sighing. "Fine."
