Try to save the world, Transmigrator!

"Hmm? You want to study at St. Freya Academy for a while?" Theresa looked at Xin Yu, who was standing before her office desk, wanting him to stay as a student for a period. She was a little unsure what was going on.

Why did this guy suddenly want to stay? Why did Kiana suddenly turn her head away?

But noticing Kiana's furtive glances, and how she was gleefully swinging the hand she held linked with Xin Yu's little finger, as if declaring her victory, Theresa's expression turned somewhat subtle.

"Kiana's academic performance isn't good. I plan to help her achieve good grades. Also, as her boyfriend, if I don't study well myself, I won't have the right to tutor her. So I promised her that I would be a student with her at the school for a while, and I also feel that my own knowledge is somewhat lacking. After all, I'm actually a high school student who hasn't even graduated, despite being over 200 years old."

Yes, this too isn't much of a problem. After all, there are tens of thousands of students at St. Freya Academy, and Theresa is still an ancient warrior who masquerades as a high school girl.

"So that's how it is. No problem, I'll get your admission procedures sorted out quickly. However, you should know that the St. Freya Academy you previously attended was destroyed because of the Third Honkai Eruption, so a lot of your information needs to be re-filled by you." Regarding Xin Yu wanting to enroll in St. Freya Academy, Theresa had absolutely no objections. After all, he was also her niece's boyfriend. In terms of character, someone willing to sacrifice their life to save others wouldn't be a bad person.

Theresa took out a paper document from a drawer in her office. The parts that needed to be filled in were all basic personal information.

Xin Yu picked up a pen from the side, and as he was writing his age, he hesitated for a moment, but ultimately, with some reluctance, he wrote down the number 16.

Even he himself had forgotten how old he was. Although he looked very young, he was certain he was already over 200. But now, maintaining a youthful appearance, it felt like he was falsifying his age if he wrote over two hundred.

Then, when it came to filling in family members, Xin Yu simply wrote "none." After all, he had indeed investigated before. The identity set for him in that background seemed to be some kind of overseas account that didn't exist, and every month, a sum of money would be transferred to the bank account he owned.

As for who opened this account, Xin Yu couldn't find out at all. Given his current situation, the only possible source of this untraceable origin was himself, who had crossed over.

After filling out the form, Theresa merely glanced at it, then put it away, before tilting her head to look at Xin Yu.

"You know, the situation at St. Freya Academy is quite special. Because it's a training ground for resisting Honkai, most of those with adaptability and resistance to Honkai are female. So, since the school's inception, there has only been one male student. Therefore, regarding your accommodation, I plan to arrange for you to stay in…"

"No need! Xin Yu can just stay with me! We are boyfriend and girlfriend; it's perfectly normal for us to live together." Kiana interrupted Theresa's words.

"Kiana, you two haven't even gotten married yet…"

"I don't have a household registration, no legal registration. Dàyímā, do you want to help me and Xin Yu get two household registrations, the kind that can be directly registered for marriage?" Theresa was rendered speechless by Kiana's retort, and finally, helpless, she rubbed her forehead and said, "Do you want to move all your things into the girls' dormitory? Or do you want your boyfriend to move into an entire girls' dormitory building?"

"That won't do! Although I can accept him cross-dressing, I absolutely cannot accept him being surrounded by a group of girls!"

"Dàyímā, I'd really rather move in with Xin Yu than have him move into a girls' dorm by himself!"

"…..Kiana! Get out! Now! Get out of my office!"

Seeing her great aunt about to lose her temper, Kiana stuck out her tongue, then winked at Xin Yu and quickly ran out.

After Kiana left, Theresa let out a long sigh, her mood somewhat calmed, and said to Xin Yu, "Apologies, I was a bit agitated just now."

"It's alright. After all, Principal Theresa is also looking out for her niece. My heart is also somewhat restless; this is also for her own good." Xin Yu, for some reason, suddenly felt a bit of anger welling up in his heart, but thinking that Theresa's actions were also for Kiana's benefit, this anger was also understandable. After all, he was for her good too.

Xin Yu didn't know where he took out a tea caddy and teacups from. He poured Theresa a cup of tea from the caddy.

Theresa looked at Xin Yu's back with some curiosity. How on earth did he conjure up a tea caddy and teacups from behind his back? She hadn't heard Xin Yu approach that place, and when she did, she found that he was already holding a set of tea caddies. Could it be that he wasn't acting like a little girl, but was actually curious and poked her?

Xin Yu sat upright, then took a sip of the tea offered by Xin Yu. After drinking it, he was slightly surprised. The taste of this tea was quite good, with a faint floral fragrance, and it seemed to alleviate some of the fatigue in his body after drinking it.

"This is some specially made tea leaves of mine. Drinking it can help one sleep better and also alleviate some bodily fatigue. Since Principal Theresa has to manage such a large academy and deal with so many complicated matters, you must be very tired. This is a small token of my respect."

Theresa accepted the tea leaves Xin Yu handed over, which were packed in a wooden box, with a slightly dazed expression. Why did she suddenly find this young man before her so pleasing to the eye! Kiana, you really found a good boyfriend.

"Regarding your accommodation, there is a two-story villa on campus that was originally reserved for specialized personnel sent from headquarters. That place isn't usually occupied by anyone, and it's also been tidied up quite a bit. There are some vacant rooms available for you to stay in, so you can go stay there."

Theresa felt that since she had accepted Xin Yu's tea leaves, and also considered him the other party's elder, she should always show some care.

"Thank you, Principal Theresa."

Xin Yu picked up the documents already prepared on the desk, the key to the small villa that Theresa had someone fetch from the school's logistics department, and a list of daily necessities to prepare.

"Right… that…" Theresa hesitated, looking at Xin Yu with some difficulty.

"You guys are still young… so… be careful with safety measures…"

Theresa felt her face at this moment must be very red, perhaps even hot.

"Of course, of course." Xin Yu understood Theresa's meaning, agreed, and then quickly left.

In fact, safety measures were completely unnecessary. After all, his own stuff… rather than calling it genetic material, it was more like some kind of liquid containing energy. Moreover, he had reproductive isolation.

This was also why he and Yae Sakura had been together for 200 years without having any children.
