The baron's swordplay was not skillful at all and he was mostly swinging his sword around with brute force. So after each forceful swing, he revealed large gaps and Weiss easily took advantage of them and wounded him again and again.
After a few exchanges, the baron suddenly started to feel dizzy and realised that he had been poisoned. This made his movements even slower and taking that opportunity, Weiss created even more wounds on his body.
The only reason he was still not dead was because he was wearing a high quality armour that only a noble was able to buy and because as an official knight, he had a strong life force which gave him extra vitality.
But still with how the situation was playing out, baron Patrick Souran was sure that after a few more exchanges, he would definitely not be able to move anymore. Seeing his current pathetic condition, Weiss spoke up again -
"Father. Do you remember testing a poison on me to see if it was effective for hunting small animals or not ? The poison I am using is the same one. I have just made it a little bit stronger."
This turn of event made the baron extremely angry. In his anger, he used all his lifeforce to strengthen himself beyond his limit.
By doing so, his agility and strength suddenly increased by a great margin and he managed to pierce Weiss's wrist with a quick and powerful sword thrust. This was a special technique that was a secret treasure of the Souran family.
With this sudden powerful move, the baron managed to disarm Weiss and her sword fell from her hand. This success made him elated. But that elation soon disappeared as he felt a mind breaking pain in his groin region.
When the sword had pierced her wrist, Weiss did not show any reaction and stayed focused on the baron. Even though she felt a lot of pain, it was not enough to even make her frown.
This degree of pain was nothing to her as her mother had regularly pierced her hands with kitchen knives and forks. So Weiss was very much used to this level of pain.
So she calmly noticed that after this sudden forceful attack, her father had lost his balance completely and had given her a golden opportunity.
So not caring about the pain, she decided to take advantage of this oppertunity and kicked her father directly in his unprotected balls.
A crushing sound was heard when her kick connected there and it was clear that Weiss had destroyed her father's family jewels.
Feeling the insane amount of pain, baron Souran also let go of his sword and stopped moving for a moment.
Weiss used that split second to kick the sword up to her hand that has fallen from her father's.
Then she coated the sword with her life force and pierced her father's heart with it while forcefully penetrating the armour.
After his heart was pierced, the green light covering the baron's body slowly faded away and he fell down on the ground with a horrified expression on his face. He was already dead.
Even for a supernaturally powerful knight like him, it was impossible to continue living after his heart was destroyed.
Seeing the death of his father by his little sister's hands, son of Baron Patrick Souran, David lost his mind in fear and wet his pants. He was extremely scared for his life now.
He had been training for almost a decade to become a offical knight but still now he was stuck in the realm of a mid level knight apprentice. As his father was not able to defeat Weiss with his strength of an official knight, he knew that he had no chance.
So David decided to use his wits to samehow save his life in this situation. As soon as Weiss turned to look at him after killing her own father, he started to beg for his life on his knees.
"Weiss, my dear little sister. I know what I have done is wrong and I promise that will never do it again. Just let me go and I will never show my face to you. I will go far away from here and start a new life.
I just don't want to die so soon. We are still blood related brother and sister at the end of the day. So please please forgive me and let me go."
"Big brother, I can easily feel your hidden killing intent toward me. You have not managed to get far in your training as a knight and now it looks like you have also failed in your basic training as a nobleman to properly hide your true feeling."
Saying this, Weiss gave David a cold and piercing look and continued -
"If I let you go, you are planning to invite count Falgur to take revenge on me, right ? That way you can get rid of me while becoming the true ruler of the Souran territory. Isn't that what you're currently planning ?" Weiss said this in a cold tone of voice.
Seeing that Weiss was able to read him like an open book, David's face turned pale white. What she had mentioned was exactly what he was planning to do.
David wanted to see his sister becoming a sex slave for the count Falgur family while he would become the next baron Souran. Why would he not desire that. All of this rightfully belonged to him.
But after getting seen through by his sister, fear filled his heart. He could not allow his sister to find out about these thoughts of his or he would definitely die. So he started stuttering in nervousness.
"N-no, how can I-i think about something like tha-"
Before he could finish his words, Weiss had already slashed her sword toward him. He was unable to show any resistance or even react to that super fast attack and his head soon rolled on the ground.
...
After killing her big brother, Weiss next looked at her mother. She was a very vicious women and whenever she was unleashing her anger on Weiss, she had always enjoyed that to the fullest.
In this family, the person who had inflicted most pain upon Weiss was this mother of hers.
But after witnessing the death of her husband and her son, the vicious nature of her heart had been suppress and she was currently acting very meek. She was looking at Weiss with a mixture of both fear and pleading in her eyes.
Weiss despised her mother from the very bottom of her heart. Weiss had an extremely powerful memory. So she could remember everything since her birth.
But among these vast amount of memories, there was not even a single moment when her mother had treated her kindly or had shown any motherly affection.
Even when she was born, what had greeted her was not a motherly look but a look of contempt because her mother was expecting a baby boy.
She was also neglected and was breastfeed only once in a while because the baron wanted his daughter to be healthy so that he could sell her off to a powerful noble family for benefit.
While Weiss was slowly coming toward her mother Sherry, she suddenly started talking in a pleading tone.
"Weiss, my dear. I'm just a powerless woman and I can't do anything to you. I have carried you for nine months inside me, so please let me live. You can take me as a prisoner. I don't mind that."
After saying this much in one breath she continued -
"I will even sleep with other nobles for you. I can teach you how to please men in bed so that you can also make good connection with other poweful noblemen. So keeping me alive is more beneficial."
That was how Sherry tried to show off her value to her blood related daughter Weiss.
