Su Xun lost his parents at a young age and relied on his elder sister Su Siqing, who became a disciple of the Taiyi Sect, one of the thirteen heavenly sects. Su Siqing cultivated the supreme sect-protecting technique Moon Shadow Illusion Sky Treasure Manual, possessed six innate spiritual roots, and achieved Heavenly Foundation Establishment, a feat unseen in a millennium. She planned to reach the Golden Core realm within three months to become the Young Peak Lord of Clear Moon Peak, which would allow her to legally bring her brother into the sect. Su Xun, stuck at the second layer of Qi Refining for years due to mediocre talent, harbored a hidden golden finger: a tiny new world connected to his consciousness. This world was barren and lifeless until he poured spiritual energy into it, accelerating its time flow and guiding its human civilization from primitive tribes to a developed cultivation society. Over two hundred years of accelerated time, the inhabitants took the basic Qi Refining Manual he taught them and relentlessly improved it, even deducing a path to Foundation Establishment. With seventy-nine Foundation Establishment cultivators now thriving, Su Xun merged his consciousness with the world's leader Su Yuan to directly absorb their optimized technique, which he called the Qi Refining Foundation Establishment Manual. Applying this enhanced technique to himself, he purified his true essence and broke through to the third layer of Qi Refining, his cultivation speed and foundation vastly improved despite consuming a high-grade spirit stone that could have powered two more years in his small world. His sister gave him her savings of twenty high-grade spirit stones over half a year, which Su Xun used mostly to accelerate his small world, knowing that once in the sect he could access better resources. Still, time was against him; the Taiyi Sect's Ascension Gate opened only once every ten years, and he could not meet the requirements of being under eighteen years old, having cultivation above the fourth layer of Qi Refining, and possessing at least three spiritual roots. Su Siqing promised to plead with her master and secretly bring him up the mountain after she became Young Peak Lord, but Su Xun felt the weight of her sacrifice. Just then, an elder named Zhou Tong, the Chief Seat of the Nine Flowers Peak of Taiyi Sect, appeared in his courtyard. Zhou Tong revealed that Su Siqing had begged him to take Su Xun as his disciple, but he warned that if Su Xun entered the sect as a mediocre appendage, he would forever stain his sister's brilliant path. Su Siqing was destined to become a peak lord or even the sect leader, but her brother's weak presence would become a target for criticism and hold her back. Zhou Tong questioned whether Su Xun was content to be a burden and suggested he try to enter the Ascension Gate by his own effort instead. Su Xun understood that his sister had bowed to others for his sake, and he resolved to change his fate. He knew his small world could provide continuous improvements to his cultivation technique; as long as he supplied spiritual energy, the civilization within would further perfect the path he taught them. Though the Ascension Gate was closing soon and his cultivation was still insufficient, Su Xun refused to give up. He decided to use every last spirit stone to accelerate the small world, hoping to glean enough insights to break through the fourth layer of Qi Refining and enter the sect on his own merit. His ultimate goal became clear: to stand beside his sister as an equal, not as a burden, and to become a true cultivator of the Taiyi Sect. The story follows Su Xun's journey from a poor, overlooked youth with a parasitic golden finger to a determined cultivator who finally harnesses his unique power to accelerate his growth, facing the conflict between relying on his sister's protection and forging his own path. The interplay between the real world and his personal small world drives his progression, with the improved Qi Refining Manual serving as his core opportunity. Su Xuns determination to protect his sisters future and prove his own worth becomes the central motive, setting the stage for his imminent struggle to enter the immortal gate.
