The next day.
After washing up, Tatsuya Shiba and the others had breakfast under the guidance of their servants and then prepared to take their leave.
Before leaving, they prepared to say goodbye to Mayumi Saegusa. What they saw instead was Yunyi holding Izumi Saegusa in his arms.
"Huh? What's going on?" Erika Chiba was the first to ask.
She had barely begun to speak when Mayumi Saegusa raised her hand to shush her.
The group walked over to Mayumi Saegusa, puzzled. Miyuki Shiba whispered, "President, what are they doing?"
" Miyuki, don't speak yet, just watch," said Mayumi Saegusa.
Everyone was puzzled by this scene.
But just then, Yunyi's voice suddenly rang out.
"Don't rely on your eyes to communicate with your Psions; use Psions feedback to pinpoint their weaknesses."
"Yes, I understand!" Izumi Saegusa replied.
She slowly closed her eyes and, following Yunyi's instructions, attempted to communicate with Psions.
Unlike the Psions within the body, establishing contact with the Psions in the outside world is no easy task. However, under the harmonizing effect of Yunyi's Domain Magic, the resistance of the Psions within the domain to Izumi Saegusa has been minimized.
A moment later, Izumi Saegusa opened her eyes, pointed to the area in front of her, and whispered, "I can feel a blurry outline there."
"Great! Next, we need to set that location as the coordinates, clearly outline the door, and then open it. Can you do that?"
"Hmm, I'll try." Izumi Saegusa held her breath and tried to trace the outline of the door, but for some reason, the marks she had just drawn a moment ago would quickly crumble.
" Brother Yunyi, I can't do it." Izumi Saegusa opened her eyes and looked at Yunyi with disappointment.
"It hurts!"
Yunyi slashed her hand with a chop, clearly annoyed.
"Are you an idiot? I asked you to draw an outline, and you actually Psions you could draw it like a painter! Don't you know you're a Psions?! You're so stupid!"
Yunyi's outburst brought tears to Izumi Saegusa's eyes. But she found the key to understanding from Yunyi's words.
She raised her hand to wipe away the tears that were about to fall, Izumi Saegusa closed her eyes and tried again.
Seeing that Izumi Saegusa was almost crying from being scolded, Kasumi Saegusa quietly snuggled closer to her older sister.
" Kasumi, it's okay if you don't come closer. After all, you don't need to learn from Yunyi-kun." Mayumi Saegusa comforted the little quail in her arms.
"Ugh, sister, Brother Yunyi is so strict!" Kasumi Saegusa complained.
"I think Little Kasumi is right, Yunyi is indeed very strict." Miyuki Shiba had also been scolded, chimed in.
Honoka Mitsui and Shizuku Kitayama nodded in agreement, seemingly sharing their viewpoint.
Hey! You guys over there, you're making too much noise!
Just as they were whispering amongst themselves, Yunyi cast a stern glance at them. The girls who had just been speaking trembled and quickly shut up and stood at attention.
A moment later, the group realized how ridiculous their actions had been. Their faces flushed, they looked at Yunyi, but this time they remained silent.
Within the domain, Yunyi observed the progress of Izumi Saegusa's drawing. Although she had received hints from Yunyi, it was still her first time trying this, and she didn't have many Psions to guide. However, her sensitivity to Spatial Magic made the outline of the door she sensed very large! As a result, she couldn't even draw the outline, let alone depict it in more detail.
Yunyi sighed softly and snapped his fingers. The next moment, a clearly depicted Imaginary Number Gate appeared before the two of them.
" Little Izumi, with your current abilities, it's impossible for you to clearly depict such a large door all at once. When you practice in the future, remember to do what you can, okay? Otherwise, if you come into contact with too many spatial elements at once, you'll get drunk again," Yunyi admonished.
Izumi Saegusa nodded, her eyes filled with envy as she watched the Imaginary Number Gate slowly dissipate.
"Rest for a bit, let your body get used to contact with spatial elements. Once you can handle more, controlling spatialized Psions will be easier."
After saying that, Yunyi canceled the Domain Magic. He turned to Tatsuya Shiba and the others and asked, "Are we going back?"
"Yes, that's what I was planning to do, so I wanted to come over and say hello," said Tatsuya Shiba.
"Oh dear, are you going back so early? You can have lunch before you leave." Mayumi Saegusa advised, after all, it seemed a bit impolite to treat Tatsuya Shiba to a barbecue after they had come all this way.
Yunyi didn't care whether they stayed or left; it was just a matter of having a few more chopsticks, and Saegusa Family wasn't short of money for food.
Seeing this Tatsuya Shiba and the others felt embarrassed to leave now, especially since they would just be playing on the beach there anyway, so they accepted Mayumi Saegusa's invitation to stay.
However, they were guests, and although they were dressed rather lightly, they hadn't brought swimsuits or anything like that. In the end, everyone decided to go for a walk on the beach; those who wanted to play in the sand could play for a while, or they could get a watermelon and cut it up.
However, just as everyone was playing on the beach, an explosion suddenly occurred underwater near the Ogasawara Islands.
In the late 21st century, most of the old energy sources have been phased out. Apart from nuclear power, which is used for military purposes, most energy sources are increasingly shifting towards new energy sources such as solar energy.
However, with the rapid development of various countries, the energy supply of solar energy has become somewhat insufficient. Therefore, countries have turned their attention to the resources in the ocean.
Not long ago, Ichijo Family Group began planning to lay cables on the seabed near the Ogasawara Islands, with the aim of mining seabed resources in the area in the near future.
However, a mistake occurred in their work: a section of the submarine cable experienced a leakage.
Normally, this situation wouldn't cause any major harm, and could be prevented with timely maintenance and repairs. However, it just so happens that the location of this electrical leak is near a rare metal mine.
The surface of the ore deposit cracked after coming into contact with a leaking current, exposing another rare element, rubidium, hidden within the vein! This ore releases heat and can even explode when it comes into contact with water!
Normally, if the volume of rubidium-containing ore is large enough and the amount of water it comes into contact with is not excessive, an explosive reaction can be avoided. However, as the surface cracks of the seabed deposit gradually expanded and the rubidium ore came into contact with more and more water, it eventually triggered a massive explosion of the seabed vein! And this vein connected to a dormant volcano hidden on the seabed!
