Endless Silver Machine

Shortly after Aika and Tylua were sent to the intensive care unit of "Mystis", their high fever and other symptoms were relieved.

While the instructors and senior students of the Pharmacy Department were still analyzing their blood samples, Aika and Tylua woke up one after another.

After emerging from the coma, the instructors allowed Luo Luo and Ling, who were waiting anxiously outside, to meet them.

Senior Tiruya was still half-lying in bed, and Aika, who had already gotten out of bed, happened to meet Lolo who hurriedly walked in.

"Brother!" Before he could say anything, Luo Luo scolded him sternly, "You can't just get out of bed and walk around now!"

"I have been fine for a long time, and I don't feel any discomfort. I am still very energetic after a good sleep..."

Aika feels that no matter what excuse she makes now, it will only make Luo Luo, who is worried about herself, more and more angry, and can only show her energetic side to her and Ling behind her.

"No matter what, you should go to bed now!"

Luoluo pushed Aika into the room without any explanation, and then noticed senior Tiluya beside him. Luoluo's strength in front of Aika suddenly weakened a lot.

"I'm sorry, Tylua-senpai, my voice was a little too loud..."

"It doesn't matter. Just like Aika said, I just had a good nap. After you came here, I became more awake."

"Senior Tiruya, we all saw what happened at that time, even if we say this now..."

The severity of sleeping and high fever coma are not on the same level at all. The seemingly comforting words of Aika and Senior Tiruya are too childish in Ling's eyes.

"This may be true for Tiruya-san. After all, half of your bloodline belongs to the vampire clan."

After receiving the notification that the two men were awake, Instructor Letika, who went to the bridge to report the investigation, immediately rushed to the monitoring room.

"I just got the report from the Pharmacy Department. Your blood sample was very active when it was sent for testing, and the abnormal indicators immediately returned to normal values."

"Because I only have half the recovery ability of a normal vampire, the initial symptoms of poisoning will probably last for a while. I'm sorry for making everyone worry."

"If I had thought calmly at that time, I should have been able to make a more accurate judgment. It turned out like this. I'm really sorry..."

Teacher Letika has been apologizing to everyone since she came back. She probably hasn't understood that everyone is very grateful to her for bringing everyone back.

Senior Tiruya didn't know how to comfort her dejected instructor. She could only smile bitterly and put on her boots and sit on the edge of the bed.

"But the situation of Aika-san is a bit incomprehensible."

When everyone felt relieved briefly because of Senior Tiruya's special physique, the next words of Teacher Letika caught everyone's attention.

"I heard that Aika only became like this because she removed Tirua-senpai's body. Didn't she wake up before Tirua-senpai because her symptoms were relatively mild?"

"I'm more concerned about another issue." Instructor Letika glanced at the Pharmacy Department's report card as if she wanted to confirm again, "Student Aika, the difference between your blood sample and Tilua's blood sample is very high. similarity."

"But Aika is a human, right? Teacher Letika, this statement is like..."

"Yes." Teacher Letika nodded and acknowledged what Ling had not finished saying, "Compared to humans..."

Although Teacher Letika has not finished speaking, everyone present has already understood what she meant.

The unspoken speculation was like a bomb that detonated in the custody room where the atmosphere had finally been relaxed.

"Impossible! If my brother is half-blood, I should be the same!"

The person who can't accept this statement the most is not Aika, but Luoluo, who is closely connected to Aika by blood.

As if she was afraid of hearing the end, she interrupted Teacher Letika's words.

"Lolo, calm down and listen to what Teacher Letika has to say first."

"Why can brother be so calm? This kind of thing is simply impossible, right?"

"Teacher Letika just said that 'the similarity is very high'. You have already started making random guesses before the specific situation is confirmed."

Aika also knew that this was just deceiving himself. He could immediately understand what Teacher Letika meant, not to mention Lolo who thought more about it than him.

It was only when he held down the excited Lolo that he felt her panic from her trembling shoulders.

Not only that, Lolo's "unspoken words" and "invisible feelings" were also conveyed to Aika's heart.

The first time I heard Luo Luo's heartfelt voice was when she regained her memory and was already regretful and crying.

At that time, Luoluo's heart was peered into by herself without any reservation. After that time, Aika never heard Luoluo's voice again.

I remember that "Light Flame Sword" once said that "Heart of Orchid" connected Luoluo and his own heart. When the feelings of one of the parties fluctuate violently, the inner feelings will flow out.

Therefore, Aika knew what Luoluo was thinking at this moment and what made her so upset.

No matter how strong his words were, Aika just hoped that Luo Luo could calm down and listen to him.

"Classmate Luoluo, I'm not sure that classmate Aika is not human, it's just that there is a possibility..."

The sudden excitement of Lolo made Teacher Letika panic for a moment.

Not only her, but even Aika did not expect that Luoluo would express his panic because of such unwarranted speculation.

Ling, who has lived with her for a year, is also aware of the reason for Luoluo's fear.

"Only you know your relationship with Aika best!"

The relationship that was once a firm one has become so sensitive now. Is it because the period when the two were closest has changed? Or are you ignoring problems that have been deliberately hidden?

Luoluo, who was frightened by Ling's scolding, finally realized her gaffe. Her hands hung down weakly, hiding her expression of shame and unwillingness under the shadow of her bangs.

"……sorry."

After a brief silence, Luo Luo raised his head again, with a shy smile on his cheek, so gentle that he couldn't even tell whether it was a genuine or fake smile.

Ling approached Luoluo. Aika thought she had something to say to her about what just happened, so she let go of Luoluo's shoulders.

But Ling didn't speak immediately. Instead, he raised his hand and pulled Luoluo into his arms, hugging her waist gently.

"Don't lose to your own heart. This world is not determined by the 'Heart of Orchid'."

"Eh? Sister Ling... or..."

At an extremely close distance, Ling whispered into Luo Luo's ear and simply let her go from his arms.

Luo Luo, who was suddenly let go, staggered back a few steps and looked at Ling with a puzzled look on his face.

Instructors Aika and Letika were far away from both of them, so naturally they didn't hear Ling's whisper to Luo Luo.

"Sister Ling, that was just now..."

"If you want to encourage Luo Luo," Ling looked at Luo Luo's confused eyes, "This is what you are really worried about."

"Ah...um..."

Luoluo nodded in understanding. She seemed to want to ask something else, but she didn't ask.

"What on earth are you talking about?"

Watching Ling and Luoluo singing and talking about topics that seemed to have nothing to do with the present, Aika was a little confused.

"nothing dealing with you."

"Hello……"

"But... why does my brother's body become like this?"

"Tirua-san, do you know the reason for this? This is my first time encountering this situation."

Instructor Letika looked at the only half-blood here, Tylua-senpai, trying to get the answer from her.

"Actually, I probably know the reason why Aika-san's blood is similar to mine." Senior Tiruya, who has been excluded from the topic, showed an awkward smile, "It's just that the atmosphere you just had, I really can't stand it. It’s convenient to interrupt…”

…………

"Classmate Aika's blood is similar to mine because I once fed him my blood."

Teruya-senpai's cheeks were slightly red as she said something that no one knew happened.

"Then it makes sense. The blood of the vampires has assimilated the blood of humans, right?"

Knowing this information, Teacher Letika immediately understood what happened to Aika.

"When did something like this happen? Aika, have you ever sucked the blood of Senior Tiruya?"

"I remember Nana said that vampires can only exchange blood with their significant other after getting married. Brother, how could you do such a thing to Senior Tiruya!"

"Who is Nana! And I have never done such a thing to Tylua-senpai! We have never even held hands!"

"Actually, you were all present at that time, but you didn't pay special attention. After all, even I myself didn't realize this problem..."

Senior Tiruya, who was sitting by the bed, heard Luoluo and Ling questioning Aika. Although she looked a little embarrassed, she still insisted on helping Aika smooth things over.

"That was when we first met a year ago. You were imprisoned by the Nemesis Society near the Imperial City Defense Bureau. Do you remember?"

"Yeah. At that time, my brother and I were imprisoned in the barrier by the man in white."

"That perverted man who was putting on airs, I still get goosebumps when I think about it."

Although a year has passed, the first contact with the Nemesis Society is still fresh in everyone's memory.

In the barrier called the "Field", Aika had no power to fight back against the man in white. It wasn't until Wei Xi opened a passage outside the barrier and Ling and Tilua came to the rescue that the man in white retreated. .

"At that time, classmate Aika was seriously injured. I didn't think much about it at the time, so I just bit my finger and fed him my blood."

"If Tirua-senpai said this..."

Aika vaguely remembered that after being rescued from the Nemesis Society, he was fed something by someone while he was unconscious, and then immediately lost consciousness.

After waking up in Liuyin's mansion, the injuries from the battle were basically healed.

"It turns out that what I drank at that time was Tylua-senpai's blood..."

"Because my blood can speed up the recovery of injuries, and this is the first time I've seen someone suffer such a serious injury. I didn't think too much about it... In short, it's me who is causing the changes in your body now. I'm sorry!"

"I have to thank Tiruya-senpai for saving me at that time. Without Tiruya-senpai's help, I might have died at that time."

During this year, the blood that Tirua-senpai fed her did not cause any trouble, and this was not an act that required her to apologize.

After the battle with Liuyin on the rocky beach outside Pufa Town, even though Wei Xi minimized the damage and was protected by Liuyin's ice coffin, Aika still rested for more than a month before taking action.

After that, he was penetrated through the abdomen by a magical mechanical attack from the underground factory in the northwest district of the imperial capital, but he was able to get out of bed and move around after only being comatose for a day. The questions he had at that time were finally answered.

"Senior Tiruya's blood has helped me a lot this year. Instead, I should thank you."

"Telua-senpai, can it be understood now that Aika is still a human being, but her physique is closer to that of a vampire?"

"Is that so..." Senior Sister Tiruya pondered for a while, then nodded vaguely, "It's probably just like Ling-san understands..."

"This understanding should be wrong."

"Eh? Isn't that so?"

The person who was most surprised by Teacher Letika's denial was actually Tylua-senpai herself.

"Tirua-san, don't you even know your own blood?"

"This is the first time I have given my blood to someone else..."

Ling and Luoluo also mentioned just now that the act of "donating blood" has special meaning to the vampire clan.

In this calm situation, Tylua-senpai would probably feel particularly ashamed every time she recalled this behavior.

However, Aika, who accepted this shameful behavior without knowing it, felt guilty towards Tirua-senpai.

"As mentioned before, Tiruya-san is a half-blood, so he only has half the abilities of a normal vampire. Aika-san must have received very little blood, right?"

"Well, only a little bit came out from my fingertips..."

"So I speculate that the vampire characteristics inherited by Aika-san only have strong resilience. And as time changes, human blood will dilute the vampire's blood, and this resilience may disappear soon."

"is that so……"

For some reason, Tylua-senpai's hope was to help Aika's body return to its original state, but her voice sounded slightly regretful.

Aika also feels regretful, not because she relied on the resilience given by Tylua-senpai, but because she just learned that this connection in about ten minutes will disappear.

"This time, Tylua-san and Aika-san have the same symptoms. It seems that it is not due to contact infection, but due to the connection of the same blood."

"Teacher Letika, what does this mean?"

Letika kept saying nouns that were not taught in class, which Aika couldn't understand at all.

"When Tiruya-san's blood was activated by the toxin, the assimilated blood in your body also underwent the same change, because the two bloods came from the same person."

"Homologous body fluids and homologous tissues have been mentioned in the pharmacy class, but they have not been explained specifically..." After instructor Letika proposed the concept, Lolo immediately thought of similar terms that he had heard in the pharmacy department. , "But will there still be a connection between the two homologous substances in vitro?"

"The blood of the vampires is a special case. But this kind of connection will only be effective when the distance is very close. This is the case tonight. Generally, this weak connection can be ignored."

"In other words, Tylua-senpai's blood won't have a big impact on my body, right?"

I don’t know if Aika understood Teacher Letika’s explanation, but he summarized the long speech above into one point.

"Well... there should be no impact that you need to worry about. Now you can move around freely."

Instructor Letika walked towards the door as she spoke. She had not finished her report on the bridge, but she patiently stayed here to explain in order to reassure everyone.

"By the way, although you have just recovered now, the operation will continue tomorrow. Our two investigation teams will gather to make plans later. You can make your own arrangements now."

Instructor Letika, who finally entered the custody room, never closed the door. As soon as she left the intensive care unit, Wei Xi walked in immediately.

I thought that Teacher Letika forgot to close the door because she was in a hurry, but it turned out that she had already expected that Wei Xi would be waiting outside the door.

"Xiao Xi, didn't you go to rest?"

"I'm sorry, but I really can't sit down with peace of mind..."

Wei Xi's torn uniform has been taken away by students from the Logistics Department, and now she is walking around the ship wearing only the pajamas she brought.

It seemed that Wei Xi had just pulled this pajama out of the box in a hurry. She didn't even dry her wet long hair. When she put it into the pajamas at random, a few strands of hair stood up.

"Telua-senpai and brother should go take a shower first."

"What about you?"

"Now just think about your own affairs. Luoluo, has the meal started now?"

"It seems so. I thought I heard a bell just now."

"I'll take your share back to the room. You and Xiao Xi can go back first."

Except for the regular set menu for lunch at "Mistas", breakfast and dinner only include pastries and drinks. Ling can bring back all the portions for five people by himself.

Ling immediately "arranged" tasks for everyone. Although he was a little arrogant, he was indeed very organized.

There was also an investigation team meeting in the evening. Considering that the time they could freely arrange was limited, Aika and Tirua-senpai did not refuse.
