The next day, I opened a portal to the palace first to get Albert and Marie. Along with the twins.
"Hey. What's our schedule?" Albert asked.
"You asked me as if I'm your assistant or something. What do you want to do first?" I asked back.
"For now, let's have Alan and Lana play with the other children first," Marie said.
It's been a while since they played with the other children. Not counting the time we were having our feast in the monsters village.
The twins unable to contain their happiness to be able to play with other children. After all, although they are happily living with their parents in the capital, it's nearly impossible for them to play with other kids. Unless there's other noble's kids about the same age as them.
Although there were some, most of them didn't stay in the capital. And only visited from time to time when Albert invited them. And he did that a lot to see if they are people he can trust or not.
"Roy, look! I can make many things with my ice!" Lana shouted as she built a sofa made of ice.
"Hmm… that's amazing. But since you're here to play with the others, there's no need to use your magic. Just play with everything around you, okay?" I said to Lana.
"Okay!"
As soon as I said that, she and her brother run to the park to meet with other children who are already playing there.
…It will be dangerous if I let her use magic whenever she wants. Good thing she did it indoor.
"…you will be a good father in the future. Unlike me," Albert said.
"It took a long time for her to not call me "Pleb" anymore though," I replied.
And to make it worse, I need to act and speak in a way that will make the twins trust me. Because we don't know if any one of them inherited Albert's ability to see through lies. I hope at least Alan inherit that ability since he will be the king in the future.
Though the future king is playing with mud along with other children outside.
"Lina and the others will watch over them. Now what?"
"How's the vampires?" Albert asked.
"You want to meet them? They are in that building. I told them that they can explore the city while being guided with Kayla or the others. But they seem to be unable to hold back their excitement," I said as I looked over the building they're in and see them getting dressed nicely.
Well, the vampires always dressed nicely. But their dress was too formal to go out. They will be seen as if they are nobles instead.
Well, some of them are indeed nobles. Vampire nobles. Though it's best to get them dressed as a hunters or just normal people so they don't cause problem.
"Let's meet them first," Albert said.
I guided the king and the queen to the next building. All of them already know that Albert and Marie are the king and the queen and be as respectful as they can.
"I brought them to a bandit extermination last night. They did well to not kill anyone. But they seem to love the taste of human's blood too much. As for the bandits, I put them in an empty island," I said to Albert.
"What will you do to them?" Albert asked.
"This might sound crazy, but I think it's best for the vampires to have a human ranch. Specially made for them so they can raise bandits or criminals for their blood. Maybe a jail is easier to say," I said.
"Hmm… I'll think about it. We'll see what happen after one month," Albert said.
We can't really decide whether the vampires will be good to work as a warden or not. Well, that is obvious. They only stayed here for one night.
As for the bandits, well, maybe killing them will give them salvation.
Man, we're here with vampires who drank the blood of humans, but I'm the cruelest one. That's just show how superior I am to them.
After seeing the vampires, it's time to go to the hospital. I didn't use portal since they want to walk around. They put on disguises by using Blobbies I gave them so they can walk around incognito. And we stopped many times before finally reaching the hospital.
Once we got to the hospital, Dean greeted us. Since he saw me with two unknown people, he instantly recognized them as the king and the queen.
"Umm… what should I call you two with?" Dean asked as he's wondering if the two want to stay incognito.
"Don't worry. We will remove our disguise once inside. You can call us by our titles or our names," Albert said.
After that, Dean brought us to the deepest part of the hospital. Where no one should go wandering about. Even the staffs in the hospital, only some who are allowed to come and go.
Of course I already have the permission. Other than me, it was Sophie who has the permission. They think that she's my assistant.
And now, she even in the lab trying to find a cure to a disease that I told her about. Since I was busy with other things, I can't do it myself. It's good to see her being helpful.
Though the main reason we're here to day is not her. We just greeted her and continue walking even deeper.
And inside, we see several people being experimented on.
It might look as if we're trying to do something evil like the Professor from the cult since we do human experiment as well. But these people are criminals on death sentence. They agree to prolong their life for medication purpose. So, it's not like we force them to be our lab rats.
Still, some of them died. That's why only doctors with strong mentality, are allowed to work on them.
…basically, mad doctors. I'm included in the list. And Dean as well. Although he didn't show it to public, he's that kind of guy who will do various experiment for the sake of humanity.
"…tell me your progress," Albert said.
"So far, we found five different blood types. For now, we call them blood type 1, 2, 3, 4, and 5. But there might be more. Using the equipment we have, we can tell those five blood types. But there are still some that we can't tell. Like Roy's blood. Which mean we still don't know what type of blood he can get," Dean said.
"Then, if he's wounded badly and in need of blood, he can't recover?" Albert asked worriedly as I'm the strongest one against the cult. I'm feel honored.
"That bring us to the next experiment. Victoria said that it's possible for a patient to get blood transfusion from their own blood. They will donate their blood weeks before surgery, and the doctors will use it. It's still in the testing though," this time, I'm the one explaining.
"That's right. For Blood Type 1 to 3, it's safe to transfuse blood from the person to themselves. But 4 and 5, there's some side effect. We don't know if there's some sort of mutation in their blood, or it's because of the blood type. That's why we will need more people to experiment on," Dean said.
"And the blood saved is in a bag?" Albert asked.
"Yes. And it's being stored in a certain box that will help us to make sure the blood can still be good as long as possible," Dean said.
"Roy. You wanted the vampires to get money so they can buy some blood? What if we lack blood in the future? Those blood bags will be useful in the war," Albert asked me.
Dean was confused because we're talking about vampires. I'll tell him later.
"Not now. Just an idea at least. Once we figure out more about blood transfusion, we can publicize our work and get more people to donate their blood. That way, we can get more. The cult might learn about this as well, but it should be fine," I said.
I mean that even if the cult learned about blood transfusion, during the war, most of them will die before getting blood transfusion. At least I'm going to make it happen that way.
And we also need to test if people with the same blood, but with different magic level can be safely have blood transfusion. There are many things that doesn't exist in Victoria's world that we have to learn from scratch. But at least Victoria's knowledge from her world helped us a lot.
"And you said that the higher magic level the mage is, the more delicious their blood for the vampires. You're going to charge them a lot of money to get the blood of an expert level mages, right?" Albert asked.
"I will also ask them to donate their blood. At least those with me. In case they are wounded in the future and Kayla's healing unable to heal them as they lost a lot of blood, they can get their own blood transfused into them. Probably, I will ask them to donate blood at least once a month," I said.
With blood transfusion, we can have higher chance of survival in the war. Even if we loss a lot of blood, we will be able to recover. But I hope the knowledge about this will spread to other doctors faster.
Marie also asked Dean about the equipment to test blood types and see if she could make an even more advanced equipment. And she even thinks of something to appraise people's magic level.
…why didn't I think of it?
Anyway, once our business here is over, we returned home. Seems like the experiment is going smoothly so far.
And since I'm someone who will fight at the frontmost area, undoubtedly, I will be the one who will need a lot of blood. I hope they can find my blood type soon. Or at least find a way to tell that it's fine if my blood can be transfused to my body later.
This is an important experiment that we have to succeed no matter what. Not only will it be great during the war, having blood for surgery will increase the chance of survival for the patient.
And this time, it's something I discovered. Not from the knowledge of the future, but from me.. Even though it's mainly from Victoria's knowledge, at least I can be proud that I'm the one who discovered this method in this world.
