當地球逐漸被深淵吞噬後，最後的倖存者終於做出一個瘋狂決定。他們不再等待末日降臨，而是主動穿越裂縫，前往宇宙邊境之外，尋找一切災難的源頭。
With Earth collapsing beneath the influence of the abyss, the final survivors abandon hope of rescue. Instead, they choose an impossible path—crossing the cosmic boundary itself to uncover what lies beyond the gate and why countless worlds have fallen before them.

基地陷入黑暗後，所有人都明白時間已經不多了。天空中的巨大眼睛持續擴張，而遍布世界各地的裂口則不斷吞噬現實。極地基地的科學家利用殘存設備推算出一個令人絕望的結果。如果裂縫繼續擴大，不到數十天，整個地球將完全與深淵融合。那時候，人類存在過的痕跡將被徹底抹去。阿誠站在觀測台前，看著冰原盡頭逐漸崩潰的天空。他知道逃亡已經毫無意義。就在此時，基地深層資料庫終於破解出部分來自山底研究計畫的隱藏紀錄。那些檔案顯示，數十年前發現的黑色物質並非單純的宇宙碎片，而是一種導航標記。它會引導智慧生命接近某個特定位置——宇宙邊境。更令人震驚的是，所有被深淵吞噬的文明，最終都曾抵達同樣的地方。科學家提出最後的計畫。他們認為巨大裂縫本身就是一條通道。如果有人能進入裂縫深處，也許能找到關閉海門的方法。雖然成功機率近乎零，但這已是人類最後的希望。阿誠、小玲與阿傑決定參與行動。三人搭乘基地改裝完成的重力穿梭艙，在無數倖存者注視下緩緩升空。當穿梭艙離開地球大氣層時，他們第一次完整看見如今的世界。冰封地球表面遍布巨大裂痕，黑色海洋在冰層下方緩慢流動，而天空中的深淵裂口幾乎覆蓋半顆星球。那些漂浮於宇宙中的巨大存在則像沉默守衛般圍繞著地球。穿梭艙接近裂縫邊緣時，所有儀器開始失常。時間顯示器不斷跳動，空間座標完全失去意義。下一秒，艙體穿過裂縫。眼前景象讓所有人陷入沉默。那裡沒有星空，也沒有宇宙。只有一片無邊無際的黑色海洋。巨大的殘骸漂浮在海面上，有破碎星球、毀滅城市、以及難以辨認的文明遺跡。天空與海洋融為一體，根本分不清上下左右。更詭異的是，海面漂浮著無數光點。當穿梭艙靠近時，小玲才發現那些竟是一段段記憶。有人類的回憶，也有來自陌生種族的片段。數十億文明的歷史像海浪般在黑暗裡漂流。阿傑開始聽見聲音。那些聲音來自海面下方，像無數亡者正在低語。他們不斷重複同一句話：「不要繼續前進。」然而穿梭艙已無法停止。遠方黑暗中，一道比銀河還巨大的輪廓正逐漸浮現。那是一扇門。一扇真正的門。海門、裂縫、深淵，都只是它投射出的影子。門表面覆蓋著無數文明留下的符號，每一道刻痕都代表一個已經滅亡的世界。當穿梭艙靠近時，門忽然自行開啟。門後方並非黑暗，而是一片純白光芒。阿誠原本以為自己即將看見宇宙的真相，可映入眼簾的景象卻遠超想像。白光之中，漂浮著無數世界。那些世界有些仍然繁榮，有些則剛剛誕生。更可怕的是，地球也存在其中，而且不只一個。數以萬計的地球同時漂浮在白色虛空裡，每一顆都經歷著不同命運。有的和平發展，有的已經毀滅，而有些則正被海門侵蝕。小玲終於明白，深淵並非單純毀滅者。它像某種篩選機制，不斷測試無數世界。就在眾人震驚之際，一道巨大身影從白光深處慢慢出現。那東西沒有固定形態，身體由星河、時間與記憶構成。它緩緩低下頭，注視著渺小的人類。然後，一個聲音直接在三人意識裡響起：「你們終於抵達邊境。」

The moment darkness consumed the polar facility, everyone understood the end was approaching. The immense eye hanging above Earth continued expanding while fractures spread across reality like cracks in broken glass. Scientists working beneath the ice reached a terrifying conclusion. If the abyss kept growing at its current rate, the planet would vanish within weeks. Not through destruction, but through absorption. Earth would simply become part of something larger, leaving no evidence that humanity had ever existed. Cheng spent hours watching the fractured sky from the observation deck. Escape no longer mattered. Then a discovery changed everything. Hidden archives recovered from the original mountain research project revealed information buried for decades. The strange black substance discovered beneath the old house was never a contaminant or organism. It was a beacon. A marker placed intentionally to guide intelligent civilizations toward a destination known only as the Boundary. Even more disturbing was the realization that every extinct civilization found in the cosmic records had eventually followed the same path. The surviving scientists proposed a final mission. If the cosmic fracture served as a gateway, perhaps its origin could be reached. Maybe somewhere beyond the abyss existed a way to stop the collapse. The odds were almost nonexistent, but no alternatives remained. Cheng, Ling, and Jie volunteered immediately. Within days, a modified gravity vessel was prepared beneath the ice. Hundreds of survivors gathered silently as the craft launched toward the dying heavens. For the first time they witnessed Earth from orbit. The planet resembled a wounded sphere wrapped in frozen oceans and black scars. Vast cracks stretched across continents while enormous entities drifted around the world like silent guardians. As the vessel approached the cosmic rupture, every system aboard began malfunctioning. Navigation coordinates dissolved into nonsense. Clocks displayed impossible values. Then the ship crossed the threshold. Everything changed. Beyond the fracture there were no stars. No galaxies. No recognizable universe. Instead an endless black ocean stretched beyond sight. Fragments of dead worlds drifted across its surface. Ruined planets floated beside shattered cities and monuments belonging to species long forgotten. Above and below became meaningless. The ocean and sky merged into one infinite darkness. Strange lights shimmered upon the black waters. As the vessel descended closer, Ling realized they were not lights at all. They were memories. Human memories. Alien memories. Entire histories belonging to civilizations scattered across countless ages. Trillions of lives drifted silently across the abyss like waves. Jie suddenly heard voices emerging from beneath the ocean. Millions of them whispered together in a language he somehow understood. They all carried the same warning. “Turn back.” But there was nowhere left to return. Far beyond the horizon, something enormous emerged from the darkness. At first it resembled a mountain. Then a continent. Finally they understood. It was a door. A real door. The sea gate, the fractures, even the abyss itself had merely been shadows cast by this unimaginable structure. Its surface was covered with symbols left behind by extinct civilizations. Every mark represented a world that had reached this place before disappearing forever. As the vessel approached, the door slowly opened. The travelers expected darkness beyond. Instead they found light. Endless white light. What existed behind the door shattered every assumption they had ever held about reality. Floating within the brightness were countless worlds. Some flourished with life. Others had only recently formed. Many had already fallen into ruin. Among them drifted thousands upon thousands of Earths. Each version existed simultaneously. Some enjoyed peace and prosperity. Others had been destroyed long ago. Many were currently being consumed by the same sea gate spreading across their own world. Ling finally understood. The abyss was not simply a destroyer. It was part of a vast process affecting realities beyond imagination. Then something moved within the light. A colossal presence emerged from the infinite white horizon. It possessed no stable shape. Galaxies, memories, and fragments of time flowed through its form like currents through water. Slowly it lowered itself toward the tiny human vessel. The three survivors could do nothing but stare. Then a voice echoed directly inside their minds. “You have finally reached the Boundary.”
