They broke open the rusted iron gate, and the five of them proceeded along the corridor; some of the rooms on either side were completely covered by soil, while parts of others still remained.

"Look, this used to be a large computer room, with steel frames filled with chips and cooling devices." Sura excitedly spoke of her discovery as she turned over a piece of rubble.

"Can these still be used?" Guy looked at the rusty and decaying structures.

"Many of the circuit boards are corroded and aged. Even if the crystals inside the chips aren't damaged, they're probably unusable." Flan shook his head.

"However, if we take these back, the Slami Association will pay a high price for them, because some of the precise components and chip structures in them can be recycled." He said while examining the shattered circuit board in his hand.

"So, they're quite valuable?" Sherry's eyes gleamed with excitement.

"Exactly. These are creations from an era of advanced ancient technology, much of which is now lost, making them naturally rare."

"Let's see what else we can find here. If we don't discover anything new, we can come back tomorrow and excavate this place thoroughly." Flan suggested.

Afterwards, the group continued to explore the corridor, discovering a hollow central hallway with several connected passageways.

"If we consider the entire ruin as a human nerve network, we probably entered through the nerve endings, and this should be a small central nerve, similar to a spine."

"And from an architectural and psychological perspective, the most crucial and important things are often placed in the center or main line." Flan drew on paper with his finger, analyzing the topography here.

As the group discussed the locations of treasures or important materials, Hexia held up a lantern, carefully examining the walls and corner facilities, pondering quietly.

There were no skeletal remains of any creatures to be found here, meaning either everything was evacuated before the ruin was abandoned, or the users of the ruins were not normal biological beings.

Judging by the one abandoned room after another found along the way, there weren't even any traces of beds or chairs, leading Hexia to feel that this was likely not a place where humans lived.

Unfortunately, the level of technology in this ruin was quite advanced, lacking any surface inscriptions, text documents, or paper materials; however, the group did find numerous crystal screens that had once been used, though none of them could be activated now.

According to Flan's calculations, the group proceeded towards the central hallway, though the passage door was closed.

"I tried using a shovel, but it wouldn't budge at all—the material it's made from is far stronger than a shovel." Guy shook his head.

"Only explosives then?" Sherry rubbed her hair.

"Even explosives would struggle." Sura replied.

"Such an alloy door must have considered explosion scenarios during construction—ordinary explosives won't open it, and larger amounts could collapse and bury the whole ruin." Though saying this, Sura was not worried or disheartened.

"So, we can only count on Hexia now."

"Me?" Tilan was a bit surprised; she indeed could break open the door, even with her bare hands, but didn't understand why Sura was so confident in her.

"Of course, if Hexia uses that sword, she'd surely succeed." Sura confidently nodded with folded arms.

It turned out to be that Personality Weapon—they almost forgot about the sword, because at her current strength, whether using the sword or not didn't make much of a difference.

"Understood." Since Sura had suggested it, Tilan didn't need to reveal anything extra and returned with Sura to retrieve the sword box hidden at the campsite.

Sherry didn't quite understand their exchange and actions, wondering why everyone believed that the delicate Hexia could break open the sturdy and thick alloy door.

"Haha, you'll find out soon." Guy patted Sherry's shoulder.

Soon, Hexia and Sura returned.

The iron sword box was opened, removing the heavy, dark red broken sword secured inside and placing it in Hexia's hand.

As she injected Magic Power into it, the sword gradually transformed from a stone-like dark red into a metallic sheen, and the grid engraved on the sword's blade glowed a deep red.

Gripping the sword, Hexia held it horizontally in the air with both hands, then walked step by step towards the alloy door, before slowly inserting it into the door.

Wisps of green smoke drifted up from the alloy door, followed by the sound of metal scraping, and as the girl slowly cut the door open with the sword, fine metal threads oozed from the seam, coiling into silver-white curved spirals.

Minutes later, the elliptical alloy panel fell, striking the ground with a heavy echo, revealing the dark corridor beyond to everyone present.

Putting away the sword, Hexia followed the group forward, inspecting the rooms along the passage.

Perhaps due to being well-sealed and protected, the preservation inside these rooms was especially intact.

"This is!" Flan exclaimed in surprise upon opening the door to see the massive bionic mechanical body towering several meters above him.

It appeared as a six-legged insect, its body made of silver metal construction, with four pyramid-shaped flying wings that spread out from its back, able to retract into a sturdy carapace. At the front were two pairs of sharp blades, and gun barrels capable of spewing high-temperature jets were on the sides of its waist and abdomen. The overall lines were smooth, conveying a sense of industrial precision and neatness.

"Is this an inactive War Machine?" The group carefully and cautiously observed, fearing that the large silver machine might suddenly awaken.

"It should be." Flan took out a lantern, turning the knob on top, using the Fresnel lens principle to concentrate the light ahead.
