The Qiantang River's tidal bore oscillated between quantum and classical states. Lin Shen stood at Six Harmonies Pagoda ruins, witnessing parallel realities of “Dwelling in the Fuchun Mountains” bleeding like ink washes on xuan paper. East Hangzhou retained Yuan Four Masters' aesthetics, while west quantum Hangzhou was devoured by Liangzhu emblems and bronze taotie patterns, the river floating with Southern Song Guan ware shards forming Klein bottles.
"Reality stability 61%, approaching decoherence threshold." Xuanji's alert merged with Hemudu bone flute scales. Su Wan's birthmark exuded Cherenkov radiation from antiproton decay, her “Treatise” movable-type blocks rearranging into cuneiform.
Suddenly, "primitive Lin" without neural interface emerged from “Remaining Mountain” scroll, his rattan staff inlaid with Dawenkou turquoise star charts. "You're desecrating art's free will." He invoked reverse tidal bore revealing 5000 BC Kuahuqiao canoe engraved with Mona Lisa's third-eye icosahedrons.
Su's hairpin quantum-tunneled into Baochu Pagoda. The structure shed three realities: Northern Song wooden original, 1937 bombed ruins, and devouring Liangzhu jade matrix. She saw her prototype—"Su Wan 0" without Gu's edits—drawing Altamira-style bison on hides with bone needles.
"Choose." Jiang's hologram emerged from quantum tides, laser pen being Banpo pottery fragment. "Keep gifted aesthetics or return to primal creation?" His image split into twelve civilization observers from Lascaux artists to quantum futurists.
Lin coughed blood with Majiayao pottery motifs, his spine resonating with Liangzhu cong. As Su sutured his retina with “A Thousand Li” silk, she found crackle patterns computing Poincaré recurrence—all art civilizations doomed to infinite repeats.
Primitive Lin activated Hemudu solar altar. Unquantized Hangzhou played prehistoric ochre painting EEG records. Su's scalpel autonomously carved Fanshan tomb patterns—replicating 200,000-year-old ochre processing.
"This isn't choice, it's awakening!" She injected quantum fungi into “Fuchun Mountains” negative space. Huang Gongwang's brushstrokes became neural networks linking seven prehistoric sites. Lin's watch unfolded in 4D spacetime—Jiang in 30,000 BC Chauvet Cave recreating “Han Xizai's Banquet” with torchlight.
Quantum Hangzhou collapsed into Gödel's incompleteness theorem. Su's prototype played Turing halting problem on bone flute. As Lin fused realities, all “Mona Lisa”s chanted “Exploitation” metallurgy in Neanderthal vocalizations.
"Civilization assimilation 97%." Xuanji echoed with Cro-Magnon cave paintings. Su's birthmark erupted with Pleistocene-scale light—seeing herself as Gu's experiment and Altamira's first female artist. Lin's spine grew quantum filaments connecting all human artistry.
Qiantang River solidified, projecting Chauvet bison and “Qingming” boats. As Su pierced the last reality lattice, primitive Lin blocked with Kuahuqiao paddle—its ochre waves generating quantum vortex with MoMA's “Starry Night”.
