He was somewhat surprised that he could do so well, even though a small body contained an adult Soul.
So he could understand that he could fool ancient people in mathematics, after all, he was not a fish that slipped through the net of nine-year compulsory education.
But the fact that he was so good in other aspects made him feel incredible.
Because he found that his memory was excellent now, it was an exaggeration to say he could remember everything at a glance, but he could remember most of it after reading it once.
This made him mutter, "Could it be the Golden Finger of a Transmigration?"
He stopped thinking about those irrelevant things; today, he made a major discovery.
He found clues to the mysterious side, or more precisely, clues to the ancient mysterious side.
Today, when he was reading "A General History of Croatia Continent," he found a passage that roughly meant:
"After the Elf race collectively left the Croatia Continent, the wars among various nations began. This war lasted for over three hundred years, directly signaling the end of the Second Era, and the Third Era gradually took the stage."
Croatia Continent was the name of the land he was currently living on.
And the Elf race, according to his memories from his previous life, was a race inherently tied to the mysterious side; they did not seem like normal humans at all.
A history book like "A General History of Croatia Continent" should not fabricate a race.
However, it was a pity that the Second and Third Eras were too ancient, and there were very few books that recorded events from those eras.
It should be noted that one era is ten thousand years, and it is currently the Fifth Era.
The time when the Elf race left was already twenty to thirty thousand years ago, so it was already quite good to have even a few words recorded over such a long span of time.
However, what puzzled him greatly was that, by era calculations, humanity in this world had developed for fifty thousand years, which was much, much longer than the original Earth civilization.
But why were the most advanced inventions still only Steam engines?
This left him completely bewildered; if this were Earth, wouldn't fifty thousand years mean directly rushing out of the Milky Way galaxy?
Alas! Difficult! But fortunately, he finally found a clue: this world does have a mysterious side, or more accurately, it once had a mysterious side.
This discovery made him somewhat excited, after all, what was the point of just being a duke who ate and waited to die? This world was very boring.
If one were to look at the progress of only developing Steam engines in fifty thousand years, by the time they managed to invent mobile phones and the internet, his grave might not even be found.
Because of his discovery, he was in a pretty good mood today.
He walked with a book tucked under his arm, humming an unknown tune, and swaggering with an arrogant gait.
"Mysterious side, huh? I wonder if there are any golden-haired, beast-eared lolis. If not, a golden-haired, beast-eared older sister would be fine too!"
He walked along, thinking about all sorts of random things. When he was lost in thought, a call suddenly interrupted him.
"Little Eros! Have you seen your sister?"
Eros was his name in this life, and his full name was Eros Lunka Nos.
Eros turned his head and saw a person with long platinum-blonde hair draped over her shoulders.
She was wearing a white fluffy long dress, with delicate and pretty features, and eyes as gentle as water.
It was his mother in this life, Estelle Yurika Nos.
As for the sister she mentioned, it was naturally Wendini Lunka Nos. According to the laws of this world, she was his only sister.
As for the rest of his half-siblings, since they were illegitimate children, Estelle would not treat them harshly, but she would not be particularly close either.
Eros shook his head, "I've been reading in my room all this time. I'm just about to go to the library to find a book. Xiao, ahem! Sister didn't come to find me today, and I don't know where she is."
He almost blurted out Xiao Mei Mei. Luckily, he reacted quickly and covered it up in time.
Estelle didn't hear anything amiss. She glanced at the book tucked under Eros's arm, bent down, kissed him on the forehead, and praised him:
"My little Eros is so well-behaved, unlike your sister. Mr. Boroka just told me that Wendini didn't go to class again today, and I don't know where she ran off to."
Feeling the soft touch on his forehead and the words that sounded like they were meant for a child,
Eros felt a tiny bit awkward, but it truly felt wonderful.
He immediately said, "Sister is still young; it's normal for her not to like studying. When she reaches my age, she definitely won't be like this."
Estelle looked at her seven-year-old son with a strange expression. Why did he say that so oddly?
"Sister is still young, and when she reaches your age... your sister is two years older than you, alright?" Looking at Eros, who acted like a little adult, she didn't know whether to laugh or cry.
She straightened up and patted Eros's head. She had to continue looking for Wendini; constantly skipping classes was not something a lady should do.
Watching her tall and beautiful figure gradually disappear, Eros truly couldn't understand. In his opinion, Estelle's beauty could definitely be described as captivating.
Yet, with such a beautiful wife at home, his old man still found a bunch of mistresses outside, which he truly couldn't comprehend.
He couldn't understand. Was it really as the previous life said? A wife is not as good as a concubine, a concubine is not as good as a mistress, and a mistress is not as good as one you can't have?
He shook his head and continued to swagger with an arrogant gait towards the library. But he hadn't walked far when a black shadow leaped out of the flowerbed and tackled him.
Eros looked at the golden-haired loli sitting on his waist, seeing the leaves stuck in many places on her clothes, and instantly knew what had happened.
No wonder Estelle couldn't find her; she was hiding in the flowerbed by the roadside.
Wendini glared fiercely at her brother, whom she had tackled, her tone incredibly fierce (truly incredibly fierce):
"Tell me, was it you who told Mama yesterday that I broke her carefully arranged flower arrangement, which made me stand for an hour?"
Eros looked at Wendini, who was sitting on him. Although her expression was fierce, perhaps because she perfectly inherited her mother's excellent looks,
Even when she was fierce, she still looked so cute to him; he wanted to pinch her cheeks. Although her tone was super fierce, it couldn't hide the soft cuteness in her voice.
Eros felt his loli Soul burning fiercely. Such a cute loli, not to mention she was his younger sister, ahem, older sister, who could resist not teasing her a little?
So he righteously said, "That's right, I said it. Didn't you break it?"
Wendini looked at her brother, who was pressed beneath her, yet showed no remorse and even acted arrogantly. She grew even angrier and roared,
"It really was you! Watch how I deal with you!"
With that, she pulled out a bottle of ink from her pocket. Clearly, she intended to use this ink to draw something on Eros's face.
But before she could act, she heard Eros say:
"If you draw on me, I'll tell Mama that you lost her necklace last time, the one she couldn't find."
"You know, that was a gift from Grandmother. Mama was sad for a long time after it went missing."
Wendini's expression froze. The ink in her hand suddenly lost its appeal.
But looking at Eros, who was still arrogant beneath her, she was really angry, so angry that she felt her lungs were about to explode.
She casually threw the ink bottle away, pressed her hands on Eros's shoulders, and shook him vigorously, muttering through gritted teeth:
"You damn tattletale, ah ah ah ah ah!!!"
Although he was being continuously shaken, Eros was in a pretty good mood at the moment.
I just love seeing you like this, wanting to get revenge on me but being utterly helpless.
