What could be inside the cave? Both of them were curious.Maybe—it really was a hidden treasure chamber on Volcano Island.But Yun Luohe and Yu Chenjin didn’t fully believe they’d be lucky enough to stumble on a treasure trove. Even getting here had been incredibly difficult—this place was anything but easy.As for whether or not to enter—One glance at each other, and they understood exactly what the other was thinking.They’d come all this way. There was no turning back. There had to be resources inside worth the risk.Yun Luohe was slightly more cautious than Yu Chenjin.She approached the entrance first and carefully inspected the surroundings.The heat was suffocating, red light and a blast of hot wind poured from within.It was obvious—the temperature inside the cave was dangerously high.At this rate, if they went in, they wouldn’t last long. Even if they kept drinking cooling beverages, they might last an hour at most.Yun Luohe activated her [Scanning Eye], staring intently into the cave for a while.“I can sense it’s very dangerous inside… but also that there are a lot of valuable things. If we go in, we’ll probably leave with our skins half peeled.”There was no chance of retreating completely unscathed.Still, she hadn’t detected any lethal-level entities, which meant there weren’t any boss-tier monsters lurking inside.If a lava behemoth suddenly emerged from the magma, they’d be dead without question—no hesitation, just run for their lives.But although she could sense danger, there wasn’t outright fear. Her subconscious recoiled from this place, but she didn’t feel it was something she couldn’t handle.Even so, there was a faint sense of unease in her chest.She didn’t know how to decide—so she wanted to hear Yu Chenjin’s opinion.If Yu Chenjin said go in, they’d charge in without hesitation.If he thought it was too risky, they’d just go back down and explore somewhere else.But knowing Yu Chenjin’s personality—If he were the kind to fear danger, he wouldn’t have crossed the lava river with her to get here in the first place.So the two of them reached an unspoken agreement: they would go in.Yun Luohe said, “Let’s get ready first.”She was still more meticulous—if they were going in, they had to prepare for everything that might go wrong.Like purchasing some protective gear from the trading center—gear resistant to toxins, fire, and extreme heat.The sulfur stench was thick, so gas masks were a must. And just in case, she decided to stock up on more antidotes.Next was new heat-resistant shoes and clothing—their gear had been worn down badly from climbing the cliffs, especially the shoes and outerwear.While shopping, Yun Luohe noticed the trading center now offered hydration sprays, so she bought two bottles just in case.Very quickly, they finished their prep and swapped into fresh equipment.Though the emergency purchases cost a bit more than usual, they’d just scored a massive haul of obsidian—they were flush with resources, and didn’t mind the expense.Yun Luohe said, “Let’s go. Once we’re in there, stay sharp.”Yu Chenjin replied, “I’ll go first.”His expression remained steady as he gripped his monk staff and stepped forward to take the lead.As they stepped into the cave, the temperature wasn’t as unbearable as expected.Inside, there was a semi-natural tunnel. Immediately visible was a spiral nautilus-like iron staircase. The passage felt about 45°C—roughly the same as outside.It probably wasn’t the deepest point yet. It would get hotter further in.Sulfurous steam seeped yellow from cracks in the stone walls—clearly toxic—but they’d both come prepared with protective measures, so it wasn’t a concern.Still, Yun Luohe could smell the sulfur, so she opened her character panel and kept checking her status at intervals. If any signs of poisoning appeared, she’d take antidotes immediately.At the bottom of the iron staircase was a nearly vertical rock fissure.They could hear the flow of magma below. At that moment, Yun Luohe realized—the entire mountain was like a massive boiler.Two iron chains hung down the stone wall. It was obvious—they’d have to use the chains to descend.The rock surface was covered in glassy lava textures, with some protrusions suitable as footholds.Without their heat-resistant suits and boots, it would be impossible to make the descent. But they were prepared.After a tough climb down, the two of them finally reached the bottom—and what they saw took their breath away.Before them stretched a crimson lava lake about seventy or eighty meters across. Red fragments floated across the surface.The entire cave floor was bathed in a strange, glowing light.Close to the lava lake, the heat was unbearable.It felt like standing inside a furnace—probably around 70°C. Their bodies felt like they were being grilled alive.Both Yun Luohe and Yu Chenjin were having trouble breathing.They quickly drank iced beverages to cool down, and finally their complexions improved.But that wasn’t enough. Thankfully, Yun Luohe had brought the [Silverback Spider Silk Blanket] Yúntūn had woven.She had Yúntūn chill it again using [Frost Mist Breath], then wrapped it tightly around her body.That helped cool her directly and let ❀ Nоvеlігht ❀ (Don’t copy, read here) her endure the heat longer.Along the lake shore, dense clusters of fern-like plants were growing.They resembled the [Volcanic Flame Ferns] they’d seen by the lava river earlier, but these were darker in color—likely a higher-grade variant.Yun Luohe didn’t rush to harvest them—her gaze was fixed on a column of obsidian in the center of the lava lake.Atop the column sat a box. A red pattern coiled around the pillar, with embedded gems the color of molten lava.Anyone with a brain could tell—that was a treasure chest.On the far side of the lava lake, there was a solid black door. A keyhole sat in the center. Clearly, they needed a key to open it.As for the key—it wasn’t hard to guess. It was almost certainly inside the chest.But how were they supposed to retrieve the box from the center of a lava lake?Yun Luohe pinned her hopes on Yúntūn.Neither she nor Yu Chenjin had a way to reach it—but for Yúntūn, it was a simple matter.All it had to do was shoot silk to latch onto the box, yank it, and pull it back.But Yun Luohe also wanted those red stones embedded in the pillar—so it would be best to drag the entire obsidian column over.That would be trickier.She spoke to Yúntūn in a low voice.Yúntūn shot out a few threads of silk, wrapping them around the obsidian column. The ice-blue silk thickened, tightening slowly around the stone.Once it was secured, it released [Frost Mist Breath] along the threads. The chill spread through the silk, and faint cracks appeared across the surface of the column.Then, Yúntūn’s silk transformed into a web, completely enveloping the pillar.Before the obsidian fractured completely, it hauled back the entire column—along with the treasure chest and the red stones on top.Yun Luohe didn’t hold back on praise. “Amazing! Yúntūn, you’re the best little beast in the world.”Yúntūn let out an excited, happy trill.Yu Chenjin, standing nearby, smiled faintly.Even though it was Yun Luohe who had given the command, Yúntūn’s flawless execution had exceeded his expectations.“So obedient. I’ll make sure to reward you with something delicious later.”Yun Luohe hugged it close and rubbed her chin against the soft fluff on its back, making Yúntūn even more excited.Yun Luohe pulled the web open.The moment she touched the chest, a task triggered.[Enter Lava Secret Chamber][Objective: Open the sealed chamber door and find the Fire Dragon Scale]She quickly had Yu Chenjin touch the chest too.As expected—he received the task as well.It reminded them of their first meeting on Spider Island, when they’d both received the sacrificial mission inside the Spider Queen’s cave.Another co-op dungeon. Not bad.Since their [Luck] values were about the same, Yun Luohe didn’t overthink it and opened the chest immediately.[Opened Lava Secret Chamber Chest. Obtained: Lava Obsidian Key ×1, Geopulse Black Boots ×1, Volcano Crystal Core ×5, Heat Resistance Potion Recipe ×1, Magma Shield Blueprint ×1]The loot was good.The [Lava Obsidian Key] was clearly for opening the chamber door. The remaining four items—they could each choose two.Without Yúntūn, they wouldn’t have been able to get this chest at all, so Yu Chenjin let Yun Luohe choose first.She picked the boots and the heat resistance potion recipe.The other two went to Yu Chenjin.[Geopulse Black Boots: Grants immunity to lava trap damage. Leaves lava footprints and temporarily freezes nearby terrain when walking. Movement speed +40%. Withstands temperatures below 70°C.]The boots were covered in obsidian-scale armor and looked seriously cool.The soles had orange-white coloring, made from a complex blend of materials. It looked like they used both lava and [Ice Crystals], which surprised them both—how had those two opposites been combined?Then again, the orange-red material might’ve been those red stones embedded in the obsidian pillar.Yun Luohe picked up the [Heat Resistance Potion Recipe].[Heat Resistance Potion: Grants 90% flame damage immunity for 30 minutes after injection. A semi-transparent heat shield forms over the skin. Can withstand temperatures up to 150°C.Side Effects: After the effect ends, body temperature drops by 5°C, [Stamina Points] -30. Must be used while [Stamina Points] are high.Recipe: Juice [Volcanic Flame Fern] leaves into pulp, add lava turtle shell powder and mix at low temperature until gelled. Finally, blend in sulfur crystals.]It was clearly an excellent potion—essentially burning [Stamina] in exchange for high-temperature resistance.Spending 30 [Stamina Points] to walk through fire for half an hour? Definitely worth it. It also cooled the body afterward, making it useful in a variety of situations.But—making it required lava turtle shell powder, which she didn’t have.Still, with a name like that, it had to be somewhere on Volcano Island—maybe even inside this lava lake.Now that the loot was split, Yun Luohe began inspecting the rest of the obsidian column’s contents.[High-Density Obsidian: A rare forging material. Enhances flame resistance in gear and used to build explosion-proof shelters.][Volcano Crystal Core: A high-grade fire element material. Core component of lava-powered reactors. Used to operate advanced machinery and weaponry.]The high-density obsidian broke into over twenty chunks.There were fifteen [Volcano Crystal Cores] in total.Although Yun Luohe and Yúntūn had retrieved them, she still gave Yu Chenjin a few pieces.Yu Chenjin handed her the [Lava Obsidian Key]. “Shall we go open the door?”“Not yet. Let me harvest the rest of the [Volcanic Flame Ferns] here first. Then we’ll eat something and top off our [Stamina Points] before heading in.”Aside from the intense heat of the lava lake, nothing dangerous had happened so far, which made her suspicious.Compared to the Spider Queen’s lair or the Bat Caverns, this place was unnaturally quiet.She had a strong feeling something was waiting behind that door.——Soon, Yun Luohe and Yu Chenjin were ready to go again.Yun Luohe held the [Lava Obsidian Key] and approached the pitch-black door.Her [Scanning Eye] couldn’t see through it—only faintly picked up on the presence of something inside.So they wouldn’t go charging in immediately once the door opened.Yun Luohe looked at Yu Chenjin. “We’ll wait a bit after it opens.”Yu Chenjin nodded. “I know.”His danger-sensing ability might not be as sharp as Yun Luohe’s, but he had some instinct for it.Yun Luohe inserted the [Lava Obsidian Key] into the door’s only keyhole.A crisp click sounded.The door opened easily.But that was only the first step of the mission.Next—they had to find the [Fire Dragon Scale].They didn’t know exactly what it looked like, but judging by the name, it would be obvious once they saw it.It was surely a high-tier material.What worried Yun Luohe most was this: if the system wanted them to find a [Fire Dragon Scale], surely there wasn’t an actual fire dragon waiting behind the door… right?She’d already ruled that out when they arrived.A fire dragon would be an unbeatable opponent. She wouldn’t have come in here if she thought that kind of thing was inside.A minute passed. The air was completely still.But Yun Luohe remained motionless—she wasn’t stepping in yet.Standing at the doorway, they could see inside the chamber.A lava stream snaked around the edge of the room, forming a glowing red ring.Several large stones floated above the lava, each with a red turtle sprawled on top.Thousands of black obsidian stalactites hung from the ceiling, dripping red corrosive liquid from their tips.Clusters of sulfur crystals dotted the floor, casting an orange-yellow glow that stood out sharply against the lava's color.Even though the resources inside were obviously abundant—and they could see the lava turtles—Yun Luohe’s expression stayed grim.They waited for quite a while. Still, nothing moved.So they finally decided to enter.The chamber was indeed very quiet.Aside from the corrosive liquid dripping from the obsidian stalactites, nothing else seemed threatening.The red turtles lay motionless in the lava, showing no signs of hostility.
