The mighty bloodline sword.

"You bastard...You were able to block me!Well, decent garbage, but can you handle another blow?" Duke Vlodbir looked at him angrily and immediately, while still finishing his words, began to attack. 

He was fast and accurate, but Viktor managed to dodge him with practically zero distance.

The duke was even more enraged when he noticed that Viktor managed to dodge another attack.

He charged with a flurry of thrusts, and shouted:

"You guys attack too!!!" As he looked at the brothers who were in shock and clearly sadder than normal vampires to see their close ones die.

They had no choice but to obey, despite being internally enraged even with the duke, they still wanted to attack this human, and they could not take revenge against someone with a higher rank than them.

'The duke is strong, as strong as T'wan.' 

'At this pace he's going to kill me.'
