Chapter 6: Surface Area

  The classroom smelled of floor wax and old paper. It was fourth period: Chemistry II. The only sounds were the scratching of pencils and the rhythmic, hypnotic ticking of the analog clock on the wall.

  Yuta stared at question number twelve on his exam paper.

  “Explain the relationship between particle size and reaction rate in a heterogeneous mixture.”

  Most students would write the textbook definition: Smaller particles have a larger total surface area, leading to more frequent collisions between reactant molecules. They would memorize the phrase "Surface Area," get the marks, and forget it by lunchtime.

  But Yuta didn't see text on a page. He saw the chipped, uneven stone mortar sitting in his inventory in Elixir Online.

  He saw the Volcanic Peppers.

  "The mortar is damaged," Yuta thought, spinning his pen between his fingers. "The bottom is uneven. I can't grind the peppers into a fine powder. I’ll be left with coarse chunks. Low surface area. Poor extraction."

  If he just added water to those chunks, the essential oils—the capsaicin—wouldn't dissolve. Capsaicin was hydrophobic. It hated water. It needed a non-polar solvent.

  I need lipids, he realized. I need fat.

  He sketched a quick diagram of a lipid molecule binding to a capsaicin molecule on the back of his exam paper. He wasn't just answering a test question; he was planning his next move.

  Connecting...

  Welcome back, Yuta.

  The transition was instant. The smell of floor wax vanished, replaced by the crisp, earthy scent of Riverwood in the morning.

  System Alert: Daily Reset Complete.

  Stamina: 100/100.

  Yuta sat on the edge of the stone fountain in the village square. He had exactly 1 Copper Coin in his inventory. He was destitute, but he had raw materials.

  He placed the heavy, chipped mortar on the fountain’s rim. He took out the three Volcanic Peppers and the severed Ember Rat Tail.

  "Let's test the hypothesis," Yuta whispered.

  He used a sharp loose stone to slice open the rat tail. Inside, running along the scorched vertebrae, was a layer of thick, yellow elemental fat. It smelled like sulfur and bacon.

  He scooped the fat into the mortar. Then, he added the peppers.

  He began to grind.

  Crunch. Scrape.

  The sound was gritty. The uneven surface of the cheap mortar made the work twice as hard. The pestle slipped and skidded. But Yuta didn't stop. He worked the pestle in a rhythmic, circular motion, forcing the coarse pepper chunks into the yellow fat.

  Chemistry took over. The lipids in the fat acted as a solvent, latching onto the oils in the pepper skins. The mixture turned from a pale yellow to a deep, angry orange. The heat remaining in the elemental fat helped soften the waxy skins, compensating for the lack of a fine grind.

  Passersby ignored him. The square was filling up with players preparing for the day's hunt.

  System Alert: Crafting...

  Progress: 100%

  Yuta scooped the thick, orange sludge into three of his clean vials. He corked them tight.

  If you find this story on Amazon, be aware that it has been stolen. Please report the infringement.

  Item Created: Ember Balm (Rank F)

  Effect: Grants "Warmth" buff for 10 minutes. Prevents "Chilled" status.

  Side Effect: Minor Skin Irritation.

  He had three vials. He had 1 Copper. It was time to enter the market.

  Yuta walked toward the North Gate. This was the exit that led toward the foothills and the Wolf Caverns—areas known for their damp, cold winds.

  The market district near the gate was a sensory assault.

  It was a chaotic symphony of commerce. The air was thick with the smell of roasting lizard-meat on skewers, the metallic tang of polished armor, and the dust kicked up by hundreds of boots.

  "LFG! Level 5 Tank looking for Healer!" a voice boomed over the crowd.

  "Selling Wolf Pelts! 5 for 1 Silver!"

  Clang. Clang. A blacksmith was repairing a dented shield right on the street, his hammer ringing like a bell.

  Players were haggling, arguing, and inspecting gear. It was a living, breathing economy.

  Yuta found a spot near a wooden support beam. He didn't shout. He didn't have the lungs or the Charisma stat to compete with the merchants screaming about swords and shields. He just stood there, holding one of the orange vials up to the sunlight. The liquid glowed like trapped magma.

  A party of three walked past. They looked miserable. Their leather armor was stained with mud, and they walked with the heavy, trudging steps of a failed run.

  "I can't do it," the Archer complained, rubbing his arms. "My attack speed dropped by 20% as soon as we entered the cave. My fingers were too stiff to draw the bow."

  "It's the Chill debuff," the Warrior grunted. "We need fur cloaks. But the NPC charges 500 Copper for one. We're broke."

  Yuta stepped forward.

  "You don't need cloaks," he said.

  The group stopped. The Warrior, a tall guy with a cracked wooden shield, looked down at Yuta. "Who are you?"

  "I have a solution for your attack speed," Yuta said calmly. He tossed the vial to the Warrior.

  The Warrior caught it. He inspected the item details. His eyebrows shot up. "Ember Balm? Prevents Chilled status?"

  "For ten minutes," Yuta explained. "Rub it on your joints. Hands, elbows, knees. It keeps the blood flowing. No stiffness. No speed penalty."

  "Rank F?" The Archer scoffed, reading over the Warrior's shoulder. "It says 'Causes Skin Irritation'. It creates an itch?"

  "It tingles," Yuta corrected. "But ask yourself: Would you rather itch for ten minutes, or would you rather freeze and die again?"

  The group exchanged looks. The logic was undeniable. They had already lost XP from dying once. They couldn't afford another failure.

  "How much?" the Warrior asked.

  Yuta did the calculation quickly.

  Ingredients: Free (Looted).

  Vials: 2 Copper each.

  Labor: High.

  "10 Copper per vial," Yuta said.

  "That's..." The Warrior hesitated. "That's fair. The Alchemist NPC sells warming potions for 50, and they taste like ash."

  The Warrior dug into his pouch. Coins clinked—the sweet sound of liquidity.

  "We'll take three. One for each of us."

  Transaction Complete.

  Received: 30 Copper.

  Items Removed: 3x Ember Balm.

  Yuta nodded. "Pleasure doing business."

  He watched them walk away, uncorking the vials and applying the orange salve to their arms. Steam began to rise from their skin as the elemental fat reacted with the air. They looked ready.

  Yuta checked his inventory.

  Starting Funds: 1 Copper.

  Sales: +30 Copper.

  Total Funds: 31 Copper.

  He felt the weight of the coins. It wasn't a fortune. It was barely a meal for a high-level player. But it was profit.

  He turned and walked back into the town, heading for the crafting district. The noise of the market faded slightly, replaced by the rhythmic pounding of the forges.

  He stopped at a run-down smithy on the corner. The NPC smith was a burly man with soot-stained skin, hammering a glowing bar of iron.

  "I need a knife," Yuta said, approaching the counter.

  The smith didn't look up. "Top shelf is steel, 1 Silver. Bottom shelf is iron, 50 Copper."

  "I can't afford those," Yuta said. "I want something from the scrap barrel."

  The smith stopped hammering. He pointed his tongs at a wooden barrel in the corner filled with rusted metal and broken handles. "25 Copper. No refunds."

  Yuta walked over to the barrel. He rummaged through the reject pile. He ignored the rusty swords and the bent daggers. He was looking for a specific shape.

  He found it. A skinning knife. The tip was snapped off, and the wooden handle was wrapped in rough twine, but the base of the blade was thick and the steel was decent. It wasn't a weapon for fighting; it was a tool for harvesting.

  "I'll take this one," Yuta said.

  He counted out the coins.

  Transaction Complete.

  Paid: 25 Copper.

  Current Funds: 6 Copper.

  He was poor again. He had gone from 1 to 31, and back down to 6. But in his inventory, he now had a Mortar, 2 empty Vials, and a Skinning Knife.

  He walked out of the village gates, past the players shouting for parties, past the merchants selling dreams.

  He headed toward the dense forest in the West. He wasn't going to the Wolf Caverns. He wasn't going to the Goblins.

  "Deer," he whispered.

  The Stags in the Western Woods were fast. They were skittish. They didn't fight back often, but catching them required patience, not firepower. They had thick hides, sinew, and fat.

  Yuta touched the handle of his broken knife.

  Others were rushing to clear dungeons. They wanted to be heroes. They wanted to see their names in lights.

  Yuta didn't care about fame.

  "I'm not ready yet," he said to the silent trees. "But I will be."

  He stepped into the shadows of the forest. The hunt was on.
