Shasha unleashed a flurry of sword strikes, while Mikhail raised his axe to block them all.
He knew that when it came to speed, he was not a match against his sister, but that was fine. He had his own way of dealing with those who moved fast, and that was what he did.
Taking minimal movements, he unleashed a slash, overpowering his sister, which caused her to uncontrollably skid backward.
A fearless smile appeared on Shasha's face, while a grin was plastered on Mikhail's.
Thirteen chuckled internally seeing that the two simply fought to the best of their abilities, forgetting that they had spectators watching them.
The exchange became more intense as both did their best to land a hit on their opponent.
Lady Callista couldn't help but nod her head in satisfaction. Although both of them didn't seem to be used to the fighting style they were using, it was still at a passable level.
She believed that before Mikhail and Shasha started their First Wandering, they would be able to refine their fighting style, allowing them to have a higher survival rate the moment they stepped into the world of Solterra.
Suddenly, with a roar Mikhail lunged forward and used his superior strength to hit Shasha's rapier, making it fly backward, disarming her.
However, Shasha wasn't fazed as she did several backflips in quick succession, catching her rapier before it fell on the ground.
Just as the two were about to clash again, they heard a clapping sound, which made both of them look at their five-year-old brother, who had a smile on his face.
"Okay, let's end the spar for now," Thirteen said. "Good job, Bro, Sis."
Mikhail and Shasha glanced at each other before lowering their weapons. This act made Lady Callista arch an eyebrow as she looked at the five-year-old, who had stopped her siblings from continuing their spar.
That alone proved that Mikhail and Shasha acknowledged their little brother and listened to his orders.
Trisha was also very surprised because she didn't expect the two to listen to their younger brother as if he were the eldest in the family.
Mikhail and Shasha then walked towards their Grandmother with looks of expectation. They were wondering what she was going to say about their performance.
"Both of you did well," Lady Callista said. "At first, I was surprised because the two of you weren't using the Leventis Battle Style. But the Martial Techniques that both of you are currently using suit both of you perfectly. By the way, who taught you those martial techniques?"
"Father taught me mine," Mikhail replied.
"Mother taught me mine," Shasha replied.
These were the replies that Thirteen had told them to use if this question came up. His father and mother had already been informed about this, and both of them agreed that this was the safest way to handle this matter.
"What Grade are these Martial Techniques?" Lady Callista inquired.
This time, it was Alessia who answered the question.
"Both of them are Gold Grade Martial Techniques," Alessia replied in a calm manner.
Lady Callista, Hans, and Trisha looked at Alessia in shock.
Gold Grade Martial Techniques were very rare and far in between.
Even the Leventis Sword Art, Heaven's Divide, was a Peak Gold-Grade Martial Technique.
"Where did you two get them?" Lady Callista asked.
"Where else, Mother?" Alessia replied. "Gerald got them while exploring Ruins in Solterra. You know he's hard at work trying to support the family."
The old lady nodded her head in understanding. "Do you plan to Auction or sell these Martial Techniques?"
"Of course not, Mother," Alessia replied. "We're not that stupid. Mikhail and Shaha will inherit these Martial Styles, so when they have a family of their own, their children will inherit their legacies."
Lady Callista found this answer acceptable and gave Trisha a side-long glance.
"If this information reaches my husband, I'll kick you out of the Villa," Lady Callista said with a smile. "You will never work for me again and never be trusted by me again."
Trisha nodded her head in understanding. "My Lady, although my employer is the Patriarch, I have not forgotten that you were the one who took me into the family. I will not betray your trust."
"Good," Lady Callista nodded. "You can give that recording crystal to my husband and let him think whatever he wants to think. But the Grade of these Martial Techniques must be kept secret no matter what."
Trisha nodded a second time. "Understood, My Lady."
Suddenly, everyone felt a fluctuation in the residence, making Alessia smile.
"It seems that Gerald has come home early," Alessia said. "Mother, let's all go and meet him."
Lady Callista smiled. "Since I'm already here, why not?"
Mikhail and Shasha went ahead to meet their father, while Alessia guided her mother-in-law to the private gateway that their family had inside the residence.
Suddenly, Shasha's scream reverberated in the surroundings, alarming Alessia, Hans, and Thirteen.
Without another word, Alessia and Hans darted toward the place where they heard the scream, drawing their weapons as they ran.
Lady Callista then asked Trisha to take her there, which the latter obeyed.
"Stay here with Remi," Lady Callista said as she handed the little girl over to Thirteen. "We'll check the situation first."
After saying those words, the two left, leaving Thirteen and Remi behind.
The five-year-old frowned, but he didn't move from his spot while hugging Remi, who had a curious look on her face.
Since he was not aware of what made his sister, Shasha, scream, he decided to not do anything reckless and wait until the adults had dealt with the situation.
They were still far too weak to do anything, and if an enemy had managed to infiltrate their residence, they wouldn't even last a few seconds before being killed.
He would only learn a few minutes later that his Father, Gerald, had suffered serious injuries and barely managed to return home after surviving an assassination attempt.
Before he lost consciousness, Gerald was able to say the name of the organization that targeted him, and it was none other than one of the top Assassin Organizations in Solterra that went by the name Death Wish.
