Forest Shroomy crouched low behind a moss-covered stump and watched the man at the edge of the eastern grove. Luke the Lumberjack. She knew him by sight, but this time something was different. He carried a case she had never seen before, metal and angular, not the tools of his trade. She moved closer, staying beneath the twisted branches of the old tree with purple and pink leaves. The bark was rough against her shoulder as she pressed herself flat. From here she could see the machine he was assembling. Orange metal, tracked wheels, an arm that extended upward with blades at the end. It was built for cutting, but not like any saw she had seen before. Luke walked a slow circle around the grove's perimeter, stopping every few meters. He bent down at each spot and brushed aside the leaf litter. Forest Shroomy pulled the test tube from her pocket and held it up to the light. Inside, the soil sample she had collected three nights ago showed the pale threads of dead mycelium suspended in dirt. The places Luke was examining matched the locations where the stranger had inserted probes into the ground. She tucked the tube away and watched him return to the machine. He climbed into the seat and reached for the controls. The engine coughed once, then roared to life. Forest Shroomy understood now. The probes had been markers. The extraction had been preparation. And this machine was here to finish what someone had started. Her forest had six days before the network collapsed, and Luke had just reduced that timeline to hours.

Forest Shroomy stepped out from behind the purple and pink tree. The machine was moving now, its blade arm lowering toward the ground. She had minutes at most before it tore through the first root channel and started the cascade that would kill everything connected below. She ran toward the old oak at the grove's edge where she kept her emergency post. The treehouse platform gave her height and a clear line of sight across the eastern section. From the deck she could see the damage already done. A line of fresh stumps cut through the grove like a wound, the earth between them churned and torn. Where the machine had passed, pale clusters of mushrooms pushed up through the disturbed soil, their caps covered in delicate webbing. The mycelium was trying to reconnect what had been severed, but it was dying faster than it could repair. Forest Shroomy pulled the test tube from her pocket and unscrewed the lid. Inside was the last viable spore sample from the healthy western network. If she could get it into the ground at the breach point before the machine cut through the main channel, the spores might take hold and create a bypass. The network would survive, weakened but intact. But she would have to cross directly into Luke's path to reach the spot in time. She climbed down the ladder and started running. The machine's engine roar grew louder as she moved through the grove. Luke saw her when she was twenty meters away. He pulled a lever and the blade arm stopped, hovering just above the ground. Forest Shroomy dropped to her knees at the soft earth between two ancient roots and dug with both hands. She poured the spores into the hole and packed soil over them, pressing hard. Behind her, Luke shut off the engine. The silence felt like a question neither of them knew how to answer. The spores were planted, but the machine was still here, and Luke was still watching.

The engine coughed once, then caught. Forest Shroomy's head snapped up from where she knelt in the dirt. Luke had restarted the machine. The blade arm began to lower again, its metal edge gleaming as it descended toward the main channel. She had seconds. The main channel ran beneath a thick exposed root shaped like a broken branch, split down its center from decades of growth. If the blade cut through it, the entire eastern network would collapse before the spores could take hold. Forest Shroomy sprinted toward the machine, waving both arms. Luke saw her but didn't stop. His hand stayed on the lever. The blade kept lowering. Forest Shroomy planted herself directly in front of the root. Luke would have to cut through her first. She held his gaze, refusing to move. The blade stopped three feet above the ground. Luke's jaw tightened. He pulled the lever back and shut off the engine again. This time he climbed down from the operator's seat. He walked past her to a wooden shelter at the grove's edge where he stored fuel and tools. Inside, he pulled a chain through the machine's wheel spokes and locked it to a support beam. Then he pocketed the key and walked away without a word. Forest Shroomy knelt beside the root and pressed her palm to the soil. Beneath her hand, she felt the first tiny mushrooms pushing through the earth where she'd planted the spores. The bypass was beginning. The machine was chained. She had bought the network time to heal, but Luke still had the key.

Forest Shroomy stayed beside the root for twenty minutes, watching the tiny mushrooms spread through the soil. They needed three more hours to establish stable connections. Then she heard boots on gravel. Luke was coming back. She stood and positioned herself between him and the machine. He carried a tool bag and the key. His eyes swept past her to the chained wheels, measuring his approach. Forest Shroomy calculated quickly. If she let him unlock the chain, the blade would tear through the bypass before it rooted. If she blocked him again, he might leave and return with help. Luke stopped six feet away and pulled the grease-slicked key from his pocket. "I'm not starting it," he said. "Just moving it off my land." Forest Shroomy glanced at the mushroom cluster pushing through the dirt around the root. The caps were barely visible above the soil, their threads still fragile beneath. She stepped forward and pointed at the ground, then held up three fingers. Three hours. Luke followed her gesture to the tiny mushrooms. His jaw worked. "Three hours and it's done growing?" She nodded once. He looked at the machine, then back at the mushrooms. Finally he dropped the key into her palm. "Three hours. Then I'm back for it." Forest Shroomy closed her fingers around the key. It was warm from his pocket and slick with oil. She had bought the network exactly the time it needed to root. When Luke returned, the bypass would hold. She knelt beside the mushrooms and pressed her free hand to the soil, feeling the threads beneath strengthen with each passing minute. The machine would leave, but the forest would survive it.

Forest Shroomy waited beside the bypass network, counting down the hours until Luke returned. The mushroom caps had spread wider through the soil, their threads growing stronger beneath. She held the machine key in her pocket and watched the eastern grove for movement. Two hours and forty minutes had passed when she heard voices. Luke appeared first, carrying a leather briefcase instead of his tool bag. A woman walked beside him wearing a bright cap with "SHROOM FOREST" stitched across the front. Forest Shroomy recognized the embroidery pattern immediately — it matched the signs at the forest's northern entrance, the ones placed by the conservation office fifteen years ago. The woman stopped ten feet from the machine and set the briefcase on a flat rock. She pulled out a pocket watch, checked the time, then looked directly at Forest Shroomy. "Two hours forty-seven minutes since he gave you the key. We're early, I know." Forest Shroomy stepped toward the bypass network, blocking their view of the mushrooms. The woman raised both hands, palms out. "I'm not here to move it. I'm here to measure." She opened the briefcase and pulled out soil testing equipment — the same brand Forest Shroomy used for pH readings. "Luke filed a land disturbance report this morning. Said someone planted an endangered species on his property line." The woman knelt near the edge of the grove, careful not to step on the new growth. "If these mushrooms are what I think they are, this whole area gets reclassified. No machines, no cutting, no disturbance for five years minimum." Forest Shroomy pulled the key from her pocket and held it out to Luke. He took it without a word. The woman collected three soil samples, labeled each tube, and closed her briefcase. "I'll have the lab results in forty-eight hours. Until then, nothing moves." She looked at Luke. "That means the machine stays exactly where it is." Luke nodded once and walked back toward the tree line, leaving the key in his pocket and the machine still chained. Forest Shroomy watched them leave, then turned back to the mushrooms. The bypass network had earned more than three hours — it had earned five years. She knelt and pressed her palm to the soil, feeling the threads pulse beneath her hand.

Forest Shroomy stood at the edge of the bypass network and watched the eastern grove for signs of movement. The conservation officer's promise hung in the air — forty-eight hours until the lab results, five years of protection if the mushrooms tested positive. But promises meant nothing if the network collapsed before then. She found the second set of probe marks three hundred yards deeper into the forest, near the oldest root channels. Six puncture holes arranged in a tight circle, each one perfectly spaced. The soil around them had already started to shift, nutrients draining away just like at the eastern grove. Forest Shroomy knelt and pushed her fingers into one of the holes. It went down eighteen inches before her hand stopped against something hard and smooth. She wrapped her fingers around it and pulled. The probe came free with a wet sucking sound — sleek metal with a hollow core, designed to draw material up from deep below. Someone had been extracting mycelium samples while she fought over the eastern grove. Forest Shroomy carried the probe back to her emergency post and measured the decay rate. At this speed, the oldest channels would fail in seventy-two hours — twelve hours before the lab results arrived. She needed to slow the drainage long enough for the classification to take effect. She worked through the night, hauling metal fencing from the northern boundary and staking it in a wide circle around the probe sites. The fence wouldn't stop someone determined, but it would slow them down and leave evidence if they tried again. By dawn, she had secured the perimeter and planted warning markers at each post. When she pressed her palm to the soil inside the fenced area, the mycelium threads felt weaker but stable. The oldest channels were holding. She had bought enough time for the conservation officer's timeline to matter. Forest Shroomy sat back against the fence and looked at the probe in her hands. Forty-eight hours until the results came. Seventy-two hours until the channels failed. The margin was thin, but it was there. She had built her defense. Now she would wait.
