My legendary class is Husband Of Deathwill Sisters?!

"I wonder where Elias Deathwill hid his high-quality straw dummies before passing you a castle, Master," Erin asked while Alex took his time to go to the treasury.

Her master grew interested in her words, urging her to speak what was on her mind, "What do you mean?"

Erin nodded within the treasury room, opening her eyes. She looked at the treasures she had never seen before Elias Deathwill's plan to find a husband for his daughters. Those items entered the treasury precisely after his escape.

And as she listened to Alex talk about his training with the straw dummies, Erin confirmed that there were high-quality straw dummies.

As the treasury spirit, Erin was the real treasure. She knew about facilities, even before Elias Deathwill gave up on the castle for his successor's sake.

"There were only low-quality straw dummies. Elias Deathwill made them after he visited the Divine Cat's Mirror World. I think he got inspired by this place!" Erin explained, stressing the last words.

Elias wouldn't be able to completely reproduce such a unique world's mechanics in a weaker continent, would he?

It was already impressive that he and his people created straw dummies that could leverage their users' battle experiences.

In a way, it could be said that Elias Deathwill's battle maniac's heart influenced facilities in the Deathwill Castle, allowing them to be what they were today.

But that was still quite odd, for Erin recalled something important, "I think he complained about their low quality, though…"

Alex listened to her voice attentively, picking up clues, "You say that he didn't keep high-quality stuff in his castle's treasury? He also kept away high-quality straw dummies from the castle…

It sounds as if he didn't have those items, to begin with," Alex casually muttered, adding more ideas to Erin's heart.

She pondered aloud, thinking about possibilities.

It would take some while for them to realize that Deathwill Castle became stronger on its own after Elias Deathwill ran away from it.

Many factors contributed to it, but the most important one was that the next owner of the castle would be named Alexander.

"We will learn about it one day," Alex chuckled before the treasury's doors. It was not a time to talk about Elias Deathwill and his weird ideas.

Alex put his hands on the treasury. In the past, those doors wouldn't even budge, for he could only pick up items from here through fate.

For example, Alex learned about The Dullahan King's Sword through Celia's authority. He wouldn't have it in his inventory if it weren't for her. Remia's Crystallized Elven Heart was the same.

But in the fairy's case, he had an easier route through the quests.

"I have gathered enough blood from the hungry demon convicts. I have more than enough contribution to step to this place!" Alex shouted, exerting his whole strength as he pushed the doors forward.

He used all his strength, his body trembling. His head went red as he held his breath, not giving up!

Alex summoned his four additional arms, adding their strength!

And the moment those hands appeared, his eyes turned red. A significant change happened slightly after, for the doors opened a little.

"I won't give up!" Alex spoke through his teeth, bringing out more power!

BANG!

At last, the doors opened!

"Ah!" Alex stumbled forward, for these doors opened as if the giants suddenly helped him, immediately spreading them.

He rolled inside, standing up with an awkward but relieved smile. The grand doors closed then, leaving him alone with Erin.

"Master! You did it!" Erin's eyes shimmered in ecstasy as she had another room where she could see and touch her master.

And as Erin's feelings were obvious, Alex boldly wrapped his hand around her waist, supporting his tired self on her curves.

Erin added her hands to help him.

In this way, Alex limped his way forward, "This is the treasury? It feels like I am in another dimension."

Alex felt like he was in a treasure, indeed. But as it was so grand and vast, he couldn't believe this place was exactly in his castle. Instead, it was as if the grand doors were portals to another world!

The place had an abundant amount of money and treasures. Everything was neatly arranged, from the quality and level recommendations.

"It's my work, Master," Erin smiled, awaiting her Master's praise.

Alex patted her head.

Erin's eyes twinkled, "So that's why Stella likes head pats so much…."

While she stood in a daze, Alex ran his eyes through the shelves. He saw swords and other items stuffed in glass, waiting for Alex to clear the prerequisites.

"I need to check items I can pick up with the hungry demons' blood," Alex opened the system, using its help to highlight items he could get even without opening the doors.

Of course, Alex hadn't fulfilled any quests.

But as former Deathwill Kingdoms' nobles had been sentenced to his prison, Alex could use their blood to pick items. He would've used it as a second option if he couldn't step into the treasury.

But now, as he was here, he could see the prerequisites of all items here. He also would be able to twist them.

For example, The Dullahan King's Sword. Elias expected Alex to raise Sara's sin significantly before giving him such a sword.

Little did he know that Celia was more than just an annoying brat.

In a similar way, Alex would be able to twist the perquisites of other items.

"Look here, Master," Erin pointed at the treasure in the middle. It was a grand item in a special showcase in such an eye-catching spot.

Alex had noticed it before but ignored it, for he looked for items he could receive first.

But as Erin wanted him to look at it, he naturally used the system to scrutinize the item.

[The Fallen Goddess' Marriage Ring(???)(Sealed)]

Alex's heart trembled as he stared at it.

"Why do I feel… some connection with this item?" Alex narrowed his eyes, feeling a fear he had never felt before.

And in the next second, unknown emotion clenched his heart.

"Ah!" Erin cried as Alex pushed her away. She didn't expect such a reaction, let alone him giving up on her curves!

But as the black torrents, similar to the darkness from The Lost Kingdom, oozed out from Alex, Erin understood that something had started influencing him.

And as he stared into his eyes, Erin's heart ached, "What is… this wrath? What have I done wrong, Master?"
