In fact, from the moment these scientists came to this world, the exchange between the two worlds had officially begun, although it was still only one-sided.

Although the people of the Castlevania do not know about this, it is no secret that among the senior officials, there are people from another world who come here.

Nathan came to see him in a curiosity, but then he went back with a helpless look on his face.

The elf secretary with green hair asked curiously: "Why are you wearing this expression? You seem to be disappointed?"

"Don't mention it." Nathan waved his hand, his expression on his face looked a little boring: "I used to think that people in another world were different, but it turned out that they were just two pairs of limbs... and there was no difference between us..."

The elf secretary smiled: "Maybe it's just a coincidence in the universe? What if one day we can discover completely different creatures?"

Now as knowledge is gradually becoming popular, even these low-level lives understand that the world they live in is just a planet in the universe.

Regarding the concept of the universe, this is basically very common in Castlevania.

Originally, this was a secret that only advanced lives could know, but now even children understand.

Nathan pulled the petite elf secretary over to Lou's arms: "It's still interesting that the race in our world is, hehe..."

"Don't, it's daytime now..."

The secretary was itchy all over his body when he touched itchy and struggled gently.

"What's wrong during the day?" Nathan looked indifferent, "Don't worry, now my king doesn't care about it, and Lord Alisha won't come to me even if she's fine."

Hearing this, the secretary struggled a little less: "That can't be like this. I play with me every day. What should I do after I get home?"

Nathan smiled and said, "It's okay, she won't mind. I have always been very interested in aliens since I was a child. Now I finally have the chance and I am always a little happy."

"Then why didn't you play with aliens before?" the elf asked with a smile.

"Are you afraid of death..." Nathan rolled his eyes, "Not to mention that there was no time at that time, and then who would dare to walk out of the guardian array at that time? But speaking of it, you elves don't seem to eat people, right?"

The elf sitting in his arms turned around and rode on his lap, smiling at him and explaining: "It's not that we don't eat people, we don't eat meat!"

Nathan was a little curious when he talked about this: "What would happen if you saw humans in the forest before?"

"Most of the time I hide," the elf explained with a smile. "The humans who dared to walk out of the guardian array in the past were basically strong people who were not easy to mess with. It is not good for both sides to have conflicts. But if they were ordinary people, they might be shot to death as a target!"

"Why?" Nathan was puzzled, "Don't you like humans?"

"Of course I don't like it," replied the elves. "We are all beautiful races like succubus, but our lifestyles are completely different. The elves will always be captured and imprisoned as slaves, and will also be auctioned as commodities..."

Nathan nodded: "I heard that some nobles do this..."

The elf poured a cup of tea and handed it to him: "So at that time, it was normal for different races to hate each other."

After taking the teacup she handed over, Nathan took a sip and his expression gradually became serious: "Then why are you..."

Seeing his expression, the elf suddenly grinned and tweaked her green hair: "What? I doubt what purpose is?"

"No..." Nathan's eyes drooped, feeling a little embarrassed, "Just a little curious..."

The elf straddled him again: "Of course it's because I'm not forced now! We will not be treated as slaves or commodities, and all actions are based on voluntary conditions. Even if we have signed a contract with our king now, he still has not forced us to do anything. We don't hate this kind of life."

"So you really like me?" Nathan's eyes lit up.

"Of course!" The elf nodded with his big eyes.

Nathan gasped excitedly: "Don't you... dislike me old?"

"Old?" The elf opposite him looked questioning, then grinned: "You are only a few decades old, why do I think you are old? Unlike me, I am over 500 years old, and my body exudes a decay smell..."

"ha?"

Nathan sniffed hard, feeling a little strange. He obviously smelled a smell with a plant fragrance, so why did she say it was a rotten smell?

Elfs are also extremely long-lived races. First-level elves can live at least a thousand years, so the concept of age may be different.

"In my opinion, you are not old at all, and your whole body smells of youth!" As she said that, she leaned over her head and kissed Nathan's head.

Nathan, who felt something was wrong, turned his head and looked out the window. Suddenly, he saw an extremely handsome male elf flying through the sky, pointing at him and asking, "What do you think of him?"

The secretary opposite shook his head, with regret in his tone: "He is really a little old. Unless he really can't help it, I don't want to play with him..."

Seeing her serious look, Nathan frowned slightly, as if he understood the essence of the problem.

After all, it seems normal for different races and the aesthetics are different from humans.

For example, the aesthetics of succubus mainly rely on smell.

…………

In the experimental building, biologist Poke explained to Niteya with an excited look on his face: "So, the succubus' sense of smell is simply beyond imagination!"

"Well," Nitia on the opposite side nodded expressionlessly, "I have read your report. What do you want to say?"

"Medical!" Poke explained with a chorus. "In our world, there are already specialized training dogs to identify diseases such as cancer. The sense of smell of succubus is much better than that of dogs, let alone advanced succubus, it is completely possible..."

"I'm sorry, there is no cancer in our world." Nitia interrupted him directly, "Maybe because of magic, people in our world will hardly get sick as long as they can eat and wear and wear."

"Uh..." Poke was stunned, "That is to say, without external factors, people in your world will not get sick?"

Niteya nodded: "There are many injuries, and there are poisoning, but all the cases of illness occur in slums. There are no cases of illness in this world's nobles!"

Olilyn next to him took over the topic: "Especially under the rule of Vikadman, my king, there is no record of illness."

Poke asked incrediblely: "You are separate to poisoning and illness... Then what should I do if I am not sick, even if I am poisoned or injured?"

Niteya thought for a while: "Alchemists can make some basic healing drugs. In the past, most of them went to church. Holy magic can detoxify and heal wounds, but the limit on their own lifespan cannot be changed. However, if you encounter a druid, it can not only heal the wound, but also extend the remaining lifespan."

"Wait," Poke asked, "If I understand correctly, the magic of the Holy attribute can cure injuries and detoxify, but there is no way to do anything about organ failure caused by aging, right?"

"Um!"

"But can the druid break through the limits of lifespan and rejuvenate the already exhausted organs?"

"You can understand that." Niteya nodded, "It's just that the druid is almost impossible to meet."

"How to say it?" Poker didn't quite understand.

"There are fewer than ten druids in the world now, and maybe even fewer!" Needia explained, "and druids don't like to communicate with other races, and basically only live in their own world."

"This..." Poke was stunned for a moment, "Do we have druids here?"

Nitia shook her head and said nothing.

"Once there!" Olilyn, who was behind, helped explain, "But in the battle some time ago, he sacrificed his life to protect my king."

Poke and others all looked regretful.

Nitia murmured to herself, "Die...?"

"That's a pity." Poker said a little regretfully, "If you can check DNA, you might be able to cultivate more..."

"Don't think about it, it's impossible." Netiya raised her head and sat on the chair. "In our world, any race combines with humans and gives birth to mixed races, but the druid should be an exception, although I have no evidence..."

"What's the meaning?"

"Druids are a combination of plants and animals, and are the most special kind of living organism in the world." Netiya explained, and seemed to be talking to herself, "This is a truly natural race, so I guess it cannot be combined with humans."

Poke nodded. Although he was a little regretful, he still made a small joke: "Thanks to the high-level life fertility rate in your world underground, otherwise the population would have been overcrowded long ago..."

…………

Inside the castle, Dikao was lying on the bed, enjoying the massage of Elisa and the others.

"Hmm..." Dikao let out a long sigh.

Grey, who was kneeling in front of him, slowly raised his head, swallowed all the drinks in his mouth, and then continued to ask with curiosity: "My King, you just said that your original world fertility rate is very high. So if you don't want to have children, how should you contraceptive?"

Dikao leaned against Alisa and smiled: "Put it in a raincoat. Simply put, put a layer of glue on this thing, and then..."

Listening to his explanation, the other succubus felt a little incredible and even a little novel.

Feiyana asked, "That world has no magic power, right? What if it breaks down?"

"There's no way." Dikao shrugged, "If you break it, you can only pray that you won't win the bid or take medicine, but this is not good for your health. The humans in my world do not have the strong physical fitness of this world. In short, it's right to be troublesome."
