It is the third evening since Onn's departure.

Iss and Camilla are taking a walk in the front yard. Due to the good weather and the approaching night, Iss can clearly see the blue light pillars connecting the sky and earth in the distance. Previously, Iss thought that this was a unique meteorological landscape of the other world. However, since learning about the history of the continent, Iss couldn't help but have some strange thoughts.

"So that's The Tower of Alexia, huh? I didn't expect it to be visible from such a distance."

"The reason why the Niro District can exist independently within the Hells Kingdom is precisely because of the protection from The Tower of Alexia. However, the one in the Niro District is the smallest among all The Towers of Alexia. It is nothing compared to the Alekandes Tower in the Pessia Lead, which you are about to inherit."

"No...that's not what I mean."

Iss murmured in a soft voice, making sure Camilla couldn't hear. What impressed him was the tower-like building that exceeded a height of one kilometer. On Earth, Iss could only think of the mythological Tower of Babel. But in this other world, there were a total of twenty-seven wonders called The Tower of Alexia.

No one knows where The Tower of Alexia came from, let alone who created it. According to the continental history that Iss has read, The Tower of Alexia first appeared a thousand years ago, during a time when the survival of humanity was at stake.

Under the command of the first queen of the unified blood race, Alver I, the united blood race launched a full-scale war against humanity. In less than five years, they defeated most of the human countries at the time. And after nearly twenty years of retreating, the scattered human countries finally formed an alliance to fight against the blood race.

However, even with this alliance, the war only shifted from a one-sided situation in favor of humans to gradually being eroded by the blood race.

Until The Tower of Alexia appeared.

A total of twenty-seven Towers of Alexia suddenly appeared on the continent a thousand years ago. At first, people regarded The Tower of Alexia as monsters and dared not approach them. It wasn't until an adventurer climbed to the top of one of the towers and discovered the secret of The Tower of Alexia that humans finally realized that the war had taken a turn.

The Tower of Alexia could absorb the magic power from the earth ley lines and use it for its own purposes. Those who controlled The Tower of Alexia could unleash large-scale magic, even manipulating the weather.

The human alliance immediately sent people to control all the Towers of Alexia that they could. They changed the weather to intense sunlight, which vampires, except for pureblood and upper-level blood races, could not withstand. The lower-level vampires, who were the main force in the war, would burn to death in the sunlight before even stepping foot on the battlefield. From that point on, the balance of the war began to tilt in favor of humans.

In addition, the demon race appeared and caused massive destruction behind the blood race. Blood Queen Alver I had to recall troops for reinforcement. After nearly a hundred years, the world gradually evolved into the current situation, with the blood race occupying half of the continent and humans taking the remaining one-fourth.

Since both the blood race and humans controlled some of The Towers of Alexia, the side that initiated the war often couldn't break through the other side's cities, even after enormous sacrifices. That's why there hasn't been any fighting between the blood race and humans for nearly a century.

"It feels like The Tower of Alexia is a prelude to an alien invasion."

"Ali...en invasion?"

Camilla tilted her head slightly, her expression full of incomprehension.

Iss quickly explained.

"Oh, what I mean is that The Tower of Alexia may not be as great as one imagines."

"In the past, many people on the continent indeed believed that The Tower of Alexia was an evil presence, saying that it was a trap set by other continents. But after a thousand years, such claims have been thoroughly debunked.""Indeed."

The reason Count Persia did not send in his army was probably because he considered the protection of The Tower of Alexia in the Nelu District, Iss yawned and thought to himself. He was just being overly concerned, like an unfounded worry.

They walked in silence for a moment, and Iss glanced at Camilla, who was half a step behind him. Her beautiful face always made him unable to help but look at her a few more times. Before traveling through time, he would never have imagined being able to talk to a girl with golden hair and red eyes like her. But this was a fact that had happened, and she even called him "Lady Sister".

"Lady Sister, do I have something on my face?"

"Oh, nothing. I was just thinking that Camilla was wearing some accessories," Iss replied embarrassedly. The accessory he referred to was the white bat headband that Camilla was wearing. Yesterday, while passing by a jewelry stall in the shopping street, Iss couldn't resist the sudden surge of the feminine side of his heart and picked out some accessories.

Naturally, he also invited Camilla to choose. However, Camilla didn't have any concept of "preference" or "liking" at all. She even felt that Iss didn't need to buy anything for someone of her low status. Helplessly, Iss could only pick out a bat-shaped headband for Camilla that was exactly the same as his, but with a different color. Camilla's was white, while Iss's was black.

"If Lady Sister doesn't like it, I can take it off."

Camilla said without any shyness or embarrassment, still maintaining her expressionless voice. She reached out to take off the headband, but Iss immediately stopped her.

"No, it's fine. I was just curious. You don't have to take it off."

Even though he didn't command Camilla to wear it, she still put it on her head. This was a positive change, although it might have been an unintentional act by Camilla.

Iss glanced at Camilla again. Today, Camilla was no longer wearing the cold black off-the-shoulder long dress. Instead, she was wearing a warm white gown that looked very cozy. Her originally elegant aristocratic temperament became more approachable.

Unfortunately, even though her appearance was perfect, her unchanged poker face made her less cute.

Although calling him "Lady Sister" with every sentence was...adorable.

Iss couldn't help but sigh.

"Haah."

"Lady Sister, do you have something on your mind?"

Camilla's question made Iss tilt his head slightly. Maybe it was just his imagination, but Camilla had been speaking more lately.

"Not to the extent of having something on my mind. It's just that the blood quality collected by Nyx is inconsistent. Sometimes, we encounter situations where all the flavors are not that good."

Regarding the quality of blood, Iss had recently discovered some interesting things. For example, even if the blood comes from the same person, if tasted by two different vampires, they would get completely different flavors. In other words, different vampires have different perceptions of blood. Some blood that he personally found to have a bad taste, turned out to be delicious when tasted by the vampire servants or blood slaves in the mansion.

Based on this conclusion, Iss finally understood why the eldest daughter of the count only took blood from females. For the body of the count's eldest daughter, male blood generally had a bitter taste. Although there were a few females whose blood also had a slight bitterness, they were in the minority. This conclusion was based on multiple experiments, and so far Iss had not found any males whose blood did not have a bitter taste.

"Can't you take blood from the blood slaves or servants in the mansion?"
