The next five days in Thornbridge passed in a blur of activity as the party prepared for Silver rank testing. They took smaller contracts during this period. Nothing was as dangerous as the Rat King, but enough to keep their skills sharp and earn additional income.

  A warehouse clearance yielded several giant spider nests and added another large amount of experience to his allies. An escort contract for a merchant traveling to a nearby village proved uneventful, but paid well. A bounty on a group of bandits operating outside the city led to a tense confrontation, but ultimately resulted in their successful capture.

  Through it all, Arin continued improving his reading skills, working through the texts Erandil had sold him. The bestiary proved particularly valuable, offering insights into the behavior and weaknesses of monsters that matched his own experiences.

  The System primer revealed something interesting about his progression. Adaptive Slimes, according to the book, were extremely rare variants that appeared roughly once per thousand normal slimes. They possessed the unique ability to absorb not just mass and essence but also skills and resistances from defeated creatures.

  That explains why my ability list keeps growing. Each new monster type I absorb can potentially grant a new resistance.

  The book also noted that Adaptive Slimes historically struggled to advance beyond Level 15, as their rapid early growth came at the cost of slower later progression. The amount of essence required for each level increased exponentially, eventually making advancement prohibitively difficult without access to high-level threats.

  Something to worry about later. For now, I'm still growing steadily.

  On the third day, Peck's party returned from their cave clearance contract with stories of encountering a nest of bat-like creatures that had proven more aggressive than expected. One of their party members had been seriously injured, forcing an early retreat.

  "The healing temple charged us half our contract payment," Peck complained when they met in the guild hall. "I swear, the prices in Thornbridge are double what they were in Greengate."

  T H A T I S H O W B I G C I T I E S W O R K

  "Yeah, I'm learning that." Peck adjusted his bow. "Heard you killed the Rat King though. That's impressive, especially for Bronze rank. You going for Silver testing?"

  Y E S I N ONE W E E K

  "We're thinking about it too, but probably not ready yet. Maybe next testing period." He paused. "Listen, my party's planning to head back to Greengate after this contract. Thornbridge is too expensive, and we're not quite at the level where the higher-paying contracts make sense."

  W I L M I S S H A V I N G F R I E N D H E R E

  "Same. But we'll cross paths again. Adventurer community's smaller than you'd think, especially in the Bronze-Silver range. Keep getting stronger, and maybe we'll end up working together on something bigger down the road."

  They parted ways with mutual wishes of good luck, and Arin reflected on how friendships worked in the adventuring world. People came together for contracts, formed bonds through shared danger, then drifted apart as their paths diverged. It was different from the more permanent connections he'd formed with the woodcutters or his party, but valuable in its own way.

  The preparation period also gave Arin time to decide about his skill points. He'd been saving them, waiting to see if a fourth skill slot made sense, but now he reconsidered.

  Two points to upgrade a skill to Tier 2. He had exactly that many saved, which meant he could upgrade one of his existing skills whenever he chose. Charge, Darkvision, or Stealth—each had potential benefits.

  Which one benefits the party most?

  Charge was his primary offensive ability, the tool he used to initiate combat or strike at vulnerable targets. Upgrading it would likely increase damage or reduce essence cost.

  Darkvision enabled him to scout effectively in dark environments like the sewers. Making it stronger might extend the range or clarity.

  Stealth was his survival tool, the ability that let him avoid detection and move unseen. A Tier 2 version would presumably drain less essence or make him harder to detect.

  He brought it up with Kelsa during a quiet moment between contracts, spelling out his reasoning that the essence drain was becoming a limiting factor for extended operations.

  "Stealth is the smart choice," she agreed. "You're the best scout I've ever worked with, and making that ability more sustainable helps the entire party. Plus, at Silver rank, we'll be facing smarter enemies. Being able to stay hidden longer could save lives."

  That settled it, stealth would get the upgrade.

  On the morning of the seventh day, Guild Master Theron summoned the party to his office with an unexpected proposition.

  "I've received a request from a minor noble in the city," he explained after they'd gathered. "His daughter has been having nightmares about monsters in her room. The family healer found no magical causes, so they believe an actual creature may be entering through the walls or windows. They want it investigated and eliminated."

  "That sounds like a Copper rank contract," Torvin said skeptically.

  "Normally, yes. But the noble is willing to pay twenty gold for the investigation because his daughter is terrified, and the family's reputation is at stake. He specifically requested a party with a good track record."

  "When?" Kelsa asked.

  "Tonight. The creature apparently only appears after dark. You'd investigate the room, identify any potential threats, and eliminate them. Simple contract, good pay, helps build connections with Thornbridge nobility."

  After Theron dismissed them to discuss, the party debated whether to take it.

  "It feels beneath us after the Rat King," Torvin said. "We're Bronze rank adventurers preparing for Silver testing, not nursemaids for noble children."

  "But twenty gold for one night's work is excellent pay," Essa countered. "And noble connections could be valuable later, especially when we eventually try to reach Vyrdan. We'll need allies in high places."

  "What do you think?" Kelsa asked Arin.

  I F C H I L D I S S C A R E D W E S H O U L D H E L P P A Y I S G O O D B U T H E L P I N G I S B E T T E R

  "Spoken like someone who actually understands what being an adventurer means," Kelsa said with approval. "Fine. We take it. One night, investigate the room, either find a creature or prove there isn't one, collect payment, and continue preparing for Silver testing."

  They met the noble family that evening at their residence in Thornbridge's upper quarter, where the wealthy maintained elaborate homes behind walled compounds. The father, Lord Brennick, greeted them with barely concealed skepticism.

  "You're the adventurers? I expected... more."

  "We're Bronze rank preparing for Silver testing," Kelsa said diplomatically. "We recently eliminated the Rat King infestation in the merchant quarter. Guild Master Theron recommended us for this contract."

  "Hmm. Yes, I heard about that." Brennick's expression softened slightly. "Very well. My daughter Lyssa is six years old. For the past week, she's been waking up screaming about a shadow monster that watches her sleep. The family healer found no curses or possession. We believe something is actually entering her room, possibly through the ventilation system."

  He led them through the mansion to Lyssa's room, a space decorated with expensive furniture and toys that spoke of significant wealth. The girl herself sat on the bed, her mother beside her, both looking tired and frightened.

  "Lyssa," Brennick said gently, "these adventurers are here to help. Can you tell them about the monster?"

  You might be reading a pirated copy. Look for the official release to support the author.

  The girl clutched a stuffed animal and spoke in a small voice. "It comes from the ceiling. It's made of shadows and has red eyes. It watches me and makes scratching sounds."

  Arin's core pulsed with recognition. That description matched something from the bestiary he'd been reading.

  I T M I G H T B E S H A D O W R A T S M A L B U T D A N G E R O U S

  "Shadow rats?" Brennick looked alarmed. "In my home?"

  "They're attracted to fear," Kelsa explained. "They feed on negative emotions and can manifest in dark places. If your daughter's been scared, that would draw them."

  "Can you eliminate them?"

  "That's why we're here."

  The party set up for a nighttime watch, with Lyssa and her mother relocating to a different room while the adventurers took positions in the child's bedroom. Arin positioned himself near the ceiling where the girl had reported seeing the creature.

  Hours passed. Midnight came and went. Arin was beginning to wonder if this had been a false alarm when he heard it—the faint scratching sound Lyssa had described.

  Movement in the shadows near the ceiling vent. Something small and dark, barely visible even to his Darkvision.

  [Shadow Rat - Level 3]

  There. A creature no larger than a normal rat, but formed from living darkness with two pinpricks of red light for eyes. It scurried across the ceiling, clearly searching for the source of fear it had been feeding on.

  Arin activated Stealth and flowed silently toward it. The shadow rat sensed movement at the last second and tried to flee, but Arin was faster. His mass engulfed the creature before it could fully disappear into darkness.

  [-3 Essence per minute]

  [+8 Mass]

  [+6 Essence]

  The absorption was unusual. The essence of the shadow rat tasted differently from that of normal creatures. More ethereal, less substantial.

  But then another scratching sound came from a different vent. And another. There wasn't just one shadow rat, there was a nest of them living in the mansion's ventilation system.

  Over the next two hours, the party hunted through the vents and walls, finding and eliminating nine shadow rats total. They were individually weak, only Level 3, but numerous and difficult to see in the darkness.

  Arin absorbed seven of them, gaining small amounts of mass and essence with each one. But more importantly, he gained something else.

  [Shadow Resistance increased to Tier 2]

  The notification surprised him. His existing Shadow Resistance had upgraded simply from absorbing multiple shadow-based creatures. This was the Adaptive Slime trait in action, his body literally adapting to the threats he encountered.

  A second notification followed.

  [Skill Available: Fear Sense - Tier 1]

  [Accept skill? This will replace one of your current skills.]

  [Fear Sense: Detect creatures experiencing fear within a moderate radius. Cost: Passive, no essence drain.]

  Arin considered it. The shadow rats had hunted by following fear, tracking the emotional signatures of their prey. Having that ability could be useful for finding hidden enemies or sensing ambushes before they happened.

  But replacing Charge, Darkvision, or Stealth? Each of those skills had saved his life multiple times. Charge gave him mobility and striking power. Darkvision made him effective in any lighting condition.

  Fear Sense was interesting, but not interesting enough.

  [Skill Declined]

  When dawn came and the last shadow rat had been eliminated, the party reported their success to Lord Brennick.

  "Nine creatures," he said, looking pale. "Living in my home's walls for gods know how long."

  "Your daughter's fear attracted them," Kelsa explained. "Now that they're gone and she knows it's safe, they won't return. Shadow rats need sustained fear to survive."

  "You’re certain that she’ll be safe now?" the Lord asked.

  "Completely. We can guarantee it."

  Brennick paid the promised twenty gold plus a bonus for eliminating more creatures than expected. But more valuable than the payment was his gratitude and the connections it might eventually provide.

  As they left the noble quarter and returned to their inn, Arin reflected on what he'd learned from this contract. Not every adventure needed to be a life-or-death battle against powerful monsters. Sometimes the most important work was helping a frightened child sleep safely, protecting people from threats they couldn't handle themselves.

  This is what Levi meant about making a difference. About helping people.

  The final week before Silver rank testing passed quickly. More contracts, more training, more preparation. The party's coordination improved with each joint operation, reaching the point where they could communicate through minimal words or gestures.

  Torvin's armor was fully repaired and upgraded with better shoulder protection. Kelsa acquired a new sword, balanced specifically for her fighting style. Essa's healing supplies were restocked, and she'd learned two new spells from the temple.

  During a contract clearing animated vines from a warehouse, Arin decided it was finally time to use his saved skill points. Two points for a Tier 2 upgrade—he had exactly what he needed.

  [Upgrade Stealth to Tier 2?]

  [Cost: 2 Skill Points]

  [Confirm? Y/N]

  He confirmed without hesitation.

  [Stealth upgraded to Tier 2]

  [Essence cost reduced to 2 per minute]

  [Detection difficulty increased significantly]

  The improvement was immediate and noticeable. When he activated the upgraded Stealth, the essence drain felt manageable rather than limiting. He could maintain it for thirty minutes now instead of twenty, and the sensation of being hidden felt stronger, more complete.

  Testing that evening confirmed the effectiveness of the upgrade. Even Kelsa, who'd grown accustomed to spotting him while hidden, had difficulty detecting his presence.

  "That's going to be incredibly useful at Silver rank," she said. "Most enemies won't even know you're there until you're already attacking."

  On the morning of their Silver rank testing, the party gathered at Thornbridge's main guild hall with dozens of other Bronze rank adventurers hoping to advance. Guild Master Theron addressed the assembled group from a raised platform.

  "Silver rank testing consists of three components," he announced. "Individual combat assessment, where you face a simulated Level 12 opponent. Team coordination trial, where your party completes an objective under time pressure. And practical application, where you take a Silver rank contract under observation."

  He paused, letting that sink in. "The individual assessment happens today. Teams that pass will schedule their coordination trial. Those who succeed at both receive a supervised contract. Pass all three, and you achieve Silver rank. Fail any component, and you remain Bronze until the next testing period."

  The testing began immediately, with adventurers called in order of registration. Arin's party watched as others entered the testing arena and emerged, some celebrating their success, while others were clearly disappointed.

  When Torvin's name was called, the dwarf entered the arena with his warhammer and shield. Through the observation windows, they watched him face a magical construct designed to match a Level 12 opponent's capabilities. The fight was brutal but methodical, with Torvin using his defensive skills to wear down the construct before finishing it with devastating hammer strikes.

  Essa's test involved facing a construct that specialized in offensive magic. She passed by using healing magic defensively while wearing it down with careful counterattacks.

  Kelsa's assessment was against a fast, mobile construct that tested her sword skills. She passed through superior technique and battle-tested reflexes.

  Then it was Arin's turn.

  He entered the arena, and the observers above activated the testing construct. It materialized as a large humanoid figure made of crystal, with four arms and glowing red eyes.

  [Testing Construct - Level 12 Equivalent]

  The construct attacked immediately, moving with speed that caught Arin off guard. Crystal fists slammed into the arena floor where he'd been standing, cratering stone. He activated Stealth and flowed aside, using his upgraded ability to avoid detection.

  [-2 Essence per minute]

  The construct paused, apparently unable to see him now. It began sweeping the arena methodically, trying to find him through area attacks.

  Arin waited for an opening, studying the construct's patterns. It had no obvious weaknesses, being made of solid crystal, but it also couldn't see him. That gave him the advantage of choosing when and where to strike.

  He used Charge, slamming into the construct's leg joint with maximum force.

  [-5 Essence]

  The impact cracked the crystal but didn't break it. The construct spun toward him, all four arms swinging, but Arin had already moved. He flowed around to the back and struck again, this time targeting where the first crack had appeared.

  Another hit. Another crack spreading through the crystal.

  The construct adjusted its tactics, creating a pulse of energy that disrupted Arin's Stealth. He became visible, and immediately all four arms targeted him.

  He took the hits, letting his mass absorb the impact while flowing away from the worst of it.

  [-34 Mass]

  But he'd learned what he needed. The construct's joints were vulnerable, and sustained damage to the same point would eventually cause structural failure.

  Arin activated Stealth again despite knowing it would be disrupted, using the brief moments of invisibility to position for better strikes. Hit and move, strike and flow, wearing down the crystal construct through persistent targeted attacks.

  The fight lasted seven minutes before the construct's leg finally failed, sending it crashing to the arena floor. Arin pressed his advantage, wrapping around the construct's head and using his acidic nature to burn into the crystal.

  It wasn't fast, but it was effective. The construct's struggles gradually weakened until it finally dissolved, defeated at last.

  [Testing Construct Defeated]

  Arin emerged from the arena to find his party waiting, their expressions filled with pride.

  "You passed," Kelsa said simply. "All four of us. Now we wait for the coordination trial."

  They had done it. Proven themselves capable of handling Silver rank threats individually. One step closer to the rank that would let them take more dangerous contracts, earn better pay, and eventually build toward Vyrdan.

  As they left the guild hall to celebrate, Arin felt his core pulse with satisfaction and determination. The journey continued, one challenge at a time, toward the answers he sought and the justice Levi deserved.

  He was level 10, his Silver rank testing underway, and a party of friends who'd become family. Not bad for a slime who'd escaped the sewers just a few months ago.

  The future was uncertain, but Arin was ready to face whatever it brought.
