Shen Yi's explanation left Mayumi Saegusa completely stunned.
She could understand these sentences individually, but the meaning they conveyed when strung together sounded so unbelievable.
"In other words, even without knowing the Activation Sequence, you can successfully cast magic simply by injecting your Psions into the engraving components inside the CAD. For example, some of the magic I used before was also engraved in the internal components." Seeing Mayumi Saegusa look, Yunyi reminded her.
After listening to Yunyi's explanation, Mayumi Saegusa understood the use of this Engraving-Type CAD. However, the confusion in her heart did not lessen much.
In Modern Magic, every step, from constructing the Activation Sequence to successfully casting the spell, is essential. However, the emergence of this Engraving-Type CAD will completely rewrite this understanding.
Seeing her bewildered expression, Yunyi simply smiled and reached out to ruffle her hair. Shen Yi, sitting opposite them, looked at the two children with a hint of disdain in her eyes.
"Alright, alright, you two, stop getting in my way and go out for a walk. I'll tidy up the archives room, and we'll grab a bite to eat together later," Shen Yi urged the two away.
After being kicked out of the archives, Yunyi and Mayumi Saegusa were both somewhat helpless.
After showing Mayumi Saegusa around the research ship, introducing her to the ship's staff, showing her the facilities in each cabin, and having a meal with Shen Yi, the two finally left the research ship and returned home.
"School starts tomorrow, Yunyi-kun, it's almost time for a new semester," Mayumi Saegusa whispered, leaning on Yunyi's shoulder.
Yunyi rolled her eyes in annoyance. "Don't mention this, it gives me a headache. Do you think those teachers at First High School are out of their minds? Why did they have to move me from Subject Two to Subject One?"
Upon hearing Yunyi's words, Mayumi Saegusa couldn't help but burst out laughing.
A few days ago, Mayumi Saegusa received a call from the principal of First High School, asking her to tell Yunyi that he would be attending Class A of the first year after the start of the new semester, and would no longer need to attend Class E of the Course 2 Student.
When Yunyi heard the news, he didn't think it was a good thing. However, after being persuaded by Mayumi Saegusa, he agreed.
"There's no other way. You've revealed too much. Even if the teacher wanted to turn a blind eye, the others wouldn't allow it! Besides, your promotion from the second subject to the first subject sets a good example for the other Course 2 Student, doesn't it? Hope is what motivates!"
Just as the two were chatting, Kasumi Saegusa and Izumi Saegusa pushed open the door and walked in. They were both middle school students, and school started earlier than usual. Seeing the two little ones skipping and jumping into the room in their uniforms, Yunyi greeted them, "Looks like you two are in a good mood today?"
Kasumi Saegusa nodded with a smile, but Izumi Saegusa pouted. She wasn't in a good mood; she was simply relieved!
At the beginning of the holiday, Yunyi was busy and didn't have time to take care of them. But when he was less busy, Mayumi Saegusa entrusted him with looking after the two sisters' magic practice.
Kasumi Saegusa's situation is alright; it's mostly routine studying. Aside from being "educated" by Yunyi a few times while learning theoretical knowledge, things are generally harmonious. But for Izumi Saegusa, it's a much tougher time.
Ever since she started learning Spatial Magic from Yunyi and mastered it, Yunyi had been teaching her this knowledge. Looking back on that process, Izumi Saegusa felt incredibly wronged.
Although Yunyi's teaching methods were quite "rough," Izumi Saegusa successfully learned several Spatial Magic application techniques. Otherwise, the little girl wouldn't have continued to be close to Yunyi.
"Hey, what's that you're wearing, sister?" Just then, Kasumi Saegusa pointed at the thing on Mayumi Saegusa's wrist and asked in confusion.
"This? It's a new CAD program." Mayumi Saegusa raised her wrist to indicate it before saying with a light laugh.
"Is it a new model? Did you buy one for us too, sister?" Kasumi Saegusa asked.
Upon hearing her question, Mayumi Saegusa's smile froze.
"This wasn't bought!"
"You didn't buy it?" Kasumi Saegusa, puzzled.
"Did your brother give it to you?" Izumi Saegusa asked.
After spending a holiday together, Izumi Saegusa of addressing Yunyi had changed from " Brother Yunyi " to the more intimate "brother".
"I guess so," Mayumi Saegusa nodded in agreement.
"Since it was given by Yunyi-kun's mother, it should be considered a gift from Yunyi-kun, right?" Mayumi Saegusa thought to herself.
"Ugh, my brother's biased," Izumi Saegusa complained.
"That's right, we want them too!" Kasumi Saegusa in.
Yunyi felt a headache coming on. It wouldn't be a problem for him to take out two of these Engraving-Type CAD and give one to each of the two little ones, but the one that Mayumi Saegusa was wearing was a special model that Shen Yi had made especially for her. Asking him to take out two identical ones right now was simply impossible.
"Well, this is the only one I managed to get. If there's another chance in the future, I'll prepare another one for you, okay?" Seeing the expectant look in the two little ones' eyes, Yunyi was too embarrassed to say no directly, so he could only express this meaning indirectly.
"Alright then, brother, don't forget about me and Kasumi's share, okay?" Izumi Saegusa reminded her before pulling Kasumi upstairs to change her clothes.
After watching the two little ones go upstairs, Yunyi finally breathed a sigh of relief. But seeing Mayumi Saegusa smirking beside him, Yunyi poked the soft flesh on her waist in annoyance.
"All you do is laugh; you don't even try to cover for me."
"They're my younger sisters, you know. As their older sister, I can't just keep ignoring them, can I?" Mayumi Saegusa brushed away Yunyi's mischievous hand.
The last day of summer vacation was spent leisurely, and the next morning, after the familiar wake-up call, Yunyi and Mayumi Saegusa went out together to First High School.
Familiar streets, familiar stations, and familiar faces.
The two had just gotten off the train at the station when they saw familiar figures gathered nearby.
"Oh, Yunyi and the president, good morning." It was Miyuki Shiba who was the first to notice the two and greet them.
"Good morning, Miyuki, and everyone else too," Mayumi Saegusa replied.
Yunyi, standing to the side, also waved symbolically, greeting everyone.
" Yunyi, I heard you've been promoted to the first department?" Leonhart asked, putting his arm around Yunyi's shoulder.
"Ah, yes, that's right." Yunyi responded, nudging Tatsuya Shiba's stomach with his elbow. " Tatsuya, don't miss me when I'm gone."
P. S.: Just got back to Beijing from a business trip, overslept today! One more chapter to finish writing and posting.
