Yan Yin, an immortal cultivation ancestor who failed her heavenly tribulation, soul-transmigrated into the interstellar world as a G-grade mental power weakling abandoned by her family. Using immortal cultivation methods such as alchemy, talisman-making, and artifact-refining to deliver a dimensional reduction strike, she opened an online store selling spiritual talismans and pills that became a viral sensation, got admitted into a military academy to slap her enemies in the face, and forged the legendary mecha "Xiuxiu" with spiritual consciousness. She healed her relatives and fiercely slew fierce beasts to become deified in a single battle, and the evil-clearing pills she crafted pierced through the conspiracy of the mysterious organization "Dark First Guild." Finally, she rallied interstellar allies to expose the mastermind, cherished mutual devotion with Lin Yansheng, a descendant of the Tianlang clan, and swept across the entire starry sky with sheer strength.
