Deep Sea Embers

A huge void is located at the end of this alleyway.

Fanna came to the edge of the hollow, the alleyway came to an abrupt end here, the ground and the ceiling disappeared in front of her as if being swallowed by something invisible, and opposite to the neat fracture, the huge and empty darkness even made her The judges all felt a huge pressure, and the instinctive fear of human beings when facing this huge dark space surged like mountains and seas.

Morris also came to the empty "entrance", he raised the lantern in his hand, but the light from the special underground lantern seemed to be swallowed directly - the light did not disappear, but because the dark space ahead was too huge So that there is nothing to reflect light in all directions, the light gradually decays in the dark, and finally only illuminates a steep slope extending downward from the pit wall, and the rest of the place is still shrouded in darkness.

"This... no matter how you look at it, it can't be the original structure in the mine." Fan Na took a light breath and looked back at the mine road that the group of people walked all the way. Stop it... this location should be the 'stone wall' mentioned in the report."

Morris bent down and carefully inspected the inner wall of a small hollow illuminated by the lantern: "It feels as if there was some kind of huge 'thing' filling here, but now that thing disappeared out of thin air, leaving A big hole."

"Such a large-scale cavity did not collapse, but stabilized?" Duncan couldn't help but frowned, and looked worried when he looked up at the darkness, "If a collapse occurs here, at least one-third of the upper I'm afraid there will be big problems in the city."

Speaking of this, he suddenly looked back at Agatha: "Are you okay? It seems that the state has not been right since just now?"

"I...can't see clearly the 'empty' you are talking about," Agatha said with some hesitation, "I can only see a huge and distorted reverberation here, and the wind is full of noise. There is really nothing in front of us. There's none?"

"It's nothing, at least visually, and I can't feel the pollution left by the extraordinary power." Fan Na nodded with certainty, and then thought deeply, "But you can feel... Maybe it's because of this place. What is left behind is resonating with you?"

"I don't know," Agatha shook her head, then turned to Duncan, "what do you think?"

"You should go in and see what's going on inside." Duncan had already made a decision, and then he waved his hand in the air, and a group of dark green flames appeared beside him out of thin air, and the skeleton bird wrapped in flames came out of nowhere. It fluttered out of the flames and landed on his shoulders with ease.

Ai Yi tilted his head and looked around: "The old driver is here! The old driver is here!"

"It cannot be ruled out that this 'cave' is at risk of collapsing, so take this pigeon with you," Duncan explained, "Don't disperse after entering, and always pay attention to whether there are signs of instability around you, and pay attention to the movement above your head. Once there are signs of collapse, Send it to everyone."

"Yes, Captain." "Understood." "Okay." "Hey..."

Duncan knocked on Alice's head casually, then confirmed the terrain at the edge of the hole, took a light breath, and was the first to step out towards the darkness.

Others followed suit.

Stepping into the hollow is a rather steep slope, and the slope is not continuous. There will be a high-low drop and a winding "fork" in the middle at any time. You must be careful every step you take, and this winding In this way, the difficult ramp continued to go deep into the darkness, as if it could reach the bottom of the hollow.

The ramp feels like a deep indentation in the rock after the effects of some long-term erosion have worn off.

Duncan walked cautiously in the dark, while the dark green flames quietly burned and spread under his feet. The endless spiritual fire illuminated the small space around the path, and left a striking "flame" behind everyone. Path", looking back, you can see the flowing fire like a thread, winding and outlining the road leading to the exit of the void in the darkness.

When exploring in such a large and dark underground space, it is very important to make good signposts. Although there are pigeon spirits as the ultimate means of evacuation, Duncan still left his own flames along the way out of caution—these flames also extended It helps him grasp the subtle changes in the inner wall of the cave at any time.

A storm sword made of ice had condensed in Fanna's hand. She held the sword in one hand, and was on the lookout for monsters that might lurk in the huge darkness. Alice held her head carefully throughout the whole process, for fear that she would be hurt by a slip of her foot. Decapitated in this darkness, Agatha was affected by some kind of "reverberation" in this cave because of her perception, so she could only be supported by Fanna, and stepped carefully on the rugged slope.

Morris was curiously observing the stones on the side of the road all the way.

"Very dense rock... and it seems to be fused and squeezed together." He raised the lantern, with a faint silver light in his eyes, and observed as far away as possible, "If the inner wall of this cave is entirely composed of this kind of rock formation, This may explain why it remains stable after its 'contents' are gone - the stones form a dense and thick 'inner shell' that supports the entire structure."

Speaking of this, he hesitated for a moment, and then said uncertainly: "However, only one inner shell may not be enough. For such a large-scale cavity, there should be other supports in the middle."

Fan Na couldn't help turning her head to look at the old man: "How many fields do you know?"

"Mathematics, history, chemistry, mysticism, physics, a little knowledge of geology and mining, and some knowledge of fighting, firearms, machinery, and blasting," Morris said casually. "Any questions?"

Fan Na was dumbfounded: "You...how did you do it?"

"It's enough to read more books," Morris said. "It's not surprising that I understand these things. After all, I am a historian."

Fan Na looked at Morris with a strange look, and thought to herself which one of the many subjects mentioned by the other party, except firearms, fighting and demolition, could be related to the professional needs of a "historian", but she hesitated. I didn't have the nerve to say it for a long time.

The expression on Agatha's face, supported by Fanna, was even weirder—this lady gatekeeper was once again deeply shocked by the followers around Captain Duncan, and the last time she had a similar feeling, she still knew that Fanna was a " When "Sports Student"...

However, Morris himself obviously did not have the self-awareness that caused everyone to marvel. At this time, his attention was once again attracted by the "stone" under his feet.

Under the light of the lantern and the green fire, the surface of these stones has a slight metallic luster, and I don't know if it's an illusion... There seem to be some special lines on their surface.

The old scholar bent down, picked up a piece of gravel, and examined it curiously.

He stopped suddenly.

Duncan also stopped, and looked curiously at the stone in Morris's hand: "Is there any problem?"

After several seconds, Morris seemed to react suddenly, and said slowly with a strange tone: "...it's boiling gold."

Agatha immediately turned her head: "Boiling gold?"

"The raw boiling gold ore is so pure that it can be stuffed directly into the steam core reactor..." Morris murmured to himself in astonishment, then quickly bent down to pick up another piece of gravel, and squatted down after checking it Come down, carefully examine every rock under your feet, the more you check, the more frightened you become, "This is also... no wonder, no wonder I felt that the texture of these 'stones' was very strange just because it was too dim can find..."

The old scholar stopped suddenly and looked up at Duncan and Agatha.

The expression on his face was astonishing, but there was also a vague excitement of having made a great discovery: "It is indeed boiling gold, captain, Agatha—this entire cave is formed entirely of boiling gold! At least it The bottom of the pit is covered with raw ore!"

Everyone fell silent, and in this silence, Duncan could clearly feel Agatha's violent ups and downs, and Fanna could even feel Agatha's body trembling slightly.

No one understands the meaning of "boiling gold" better than a native of Frost.

"It's full of boiling gold here, and we saw remnants of boiling gold veins in the mine before." Fan Na held Agatha's hand and whispered, "It seems that at least for a while, Frost doesn't have to worry too much. gone."

"Yes...don't worry...there's boiling gold here..." Agatha muttered to herself, but her tone was unusually complicated, "but why, why are there these things..."

"Will the erosion of the Youshen Lord leave boiling gold?" Duncan couldn't help frowning, "If the information is correct, that's how this big hole should come from..."

Everyone seemed to suddenly become serious, so that even Alice, who had always been unresponsive, felt the change in the atmosphere. Miss Doll couldn't help but leaned over and gently pulled Duncan's arm, and said cautiously: "Captain... What is boiling gold?"

Duncan: "..."

With everyone so serious, it's really hard for this hanhan to still be a steadfast hanhan.

He sighed: "Boiling gold is the foundation of modern industry and the energy source for all steam-powered machinery—just like people need to eat, machines also need boiling gold to run."

Alice listened half-understood, and nodded suddenly after a long time: "Oh——"

Duncan didn't care whether the illiterate puppet really understood, and his eyes once again turned to the dark depths ahead.

This huge underground cavity has completely aroused his curiosity.

If the entire cave is made of extremely high-purity boiling gold... then what is waiting for him in the deepest part of the cave?
