Actually, it seems the path to the Duke’s Library doesn’t necessarily require obtaining the Royal Artifact to be opened.

It’s just that after acquiring the Royal Artifact, the Sain Dungeon will provide indications about the existence of the path’s location, and before that, this road is obscured by an illusion similar to a hidden door.

Fingerley only found out about this afterward.

Even though adventurers know there are hidden doors within the Sain Dungeon, they wouldn’t idly suspect that a random wall in the wide open space of the sunny Royal City could be a hidden door, right? Generally, only in those complex passageways would people start considering the possibility of hidden doors.

The Sain Dungeon uses people’s habits against them.

After defeating the Steel Giant Puppet, all Fingerley and his companions had to do was take the Bat Monster’s Express to reach Yanor Londo, getting a chance to catch their breath along the way.

Nadi was observing the surroundings throughout the journey, trying to memorize the route with her memory, perhaps next time she wouldn’t need the Bat Monster’s help, and could transform into a giant dragon, carrying everyone to Yanor Londo, maybe even bypass the Steel Giant Puppet and fly straight there!

However, she quickly realized that upon flying, they experienced a scarcely noticeable teleportation, and then the outline of Yanor Londo appeared on the horizon.

Such a seamless scene switch...

After all, the City Lord of the Sain Dungeon wouldn’t invest a large amount of spiritual power to create a big map solely for the Bat Monster to fly, the adventurers seemed to be carried by the Bat Monster to Yanor Londo, but in reality, they underwent a teleportation.

Meanwhile, on the other side, three Magic Professors were researching the numerous rewards obtained from the Boss Monster.

"Turns out it’s not possible."

Hades held the item known as the Core of Steel Giant Puppet in his hand, letting out a sigh.

He originally thought the core that could drive the Steel Giant Puppet must be packed with powerful energy, and such an item with immense energy outside the dungeon would certainly have uncountable uses.

But after the research, he realized this thing was just a façade.

Rather than being the core that provides energy to Steel Giant Puppet, it’s more like a key, a key given by the Sain Dungeon to those who defeat the Steel Giant Puppet to exchange rewards, it has no other function aside from exchanging rewards...

Not only is the core of the Steel Giant Puppet like this, items such as the soul of the Chaos Witch are the same, they have no other uses except for trading with the Sain Dungeon.

This is a clever cost-effective idea from the Sain Dungeon.

Hades could understand this, in his understanding, the Sain Dungeon uses some power to reproduce figures from the past, and the reproductions are definitely not the same as the real ones, whether it’s the core or the soul having such issues doesn’t matter.

"A pity, I wanted to try replicating the Steel Giant Puppet."

He shook his head, tucking the Core of Steel Giant Puppet back into his chest, and at that moment, the Bat Monsters had already reached the sky over Yanor Londo, successfully landing on the terrace.

Fingerley’s familiarity with Yanor Londo was even higher than with his remembered hometown, so he led the way in front, not spending much time at all to reach the winding staircase leading to the Duke’s Library.

"Back again."

He sighed, recalling the overwhelming pressure from the White Dragon Heiss in his memory, for a moment his legs resisted the brain’s command to step onto the staircase.

A heavy thud from behind caught his attention; he turned and saw Nadi among three people and a dragon, all suddenly donned in heavy armor, the thickness and weight making even a warrior like him twitch his eyelids.

Surely it would affect movement, right? Normally fragile magicians opt for donning heavy armor at the expense of mobility, is this trade-off worthwhile?

The place where Fingerley most wanted to complain was—

"Do dragons really need to wear armor?" he said to a struggling Nadi "Is this stuff sturdier than your dragon scales?"

"This is my research on magic heavy armor, compared to her scales it’s hard to say." Turci said with a hint of pride, pulling out an extra set of armor from the Space Ring and tossing it to Fingerley.

"I only just noticed you’re carrying such a rare treasure as a Space Ring."

Fingerley was complaining about how heavy armor affected movement, yet his hands obediently put on the armor, sadly the crystallized right hand couldn’t wear the arm armor.

Because he knew he wasn’t the main force of this battle, at most he was a guide and a backup.

"It’s precisely due to your crystallization that she also needs to wear armor, we don’t want her to grow crystals affecting combat power." Vienma pointed at Lady Nadi, who was bouncing around in curiosity for wearing armor for the first time, the movements even made people see the shadow of her daughter, Fudolin, on her.

"So this bears magic specifically targeting crystallization."

Magic targeting crystallization?

This piqued Fingerley’s curiosity, what kind of magic could it be, could it be a magic shield of a different nature?
