Deep within the capital city, in the quiet, ancient alleys, lies Lin Chen, a seemingly gentle young man who carries the thousand-year legacy of the Northern Song Dynasty's "Wen Shu Ge" (Literary Pavilion). He can play the zither, evoking the totems of civilization and stunning the world; he can appraise and date treasures, making a decisive judgment at Panjiayuan Market; and he possesses both "a heart of zither and a heart of swordsmanship," his ancient martial arts moves imbued with the fantastical light and shadow of intangible cultural heritage, repelling enemies without a trace.

Faced with the Qin family's commercial strangulation, the "Black Cross" organization's cultural plunder, and the open and covert attacks of international forces, he joins hands with the gentle ancient book restorer Su Qingwan, the charming business queen Shen Mei, the fiery ancient martial arts successor Chu Yao, and the capable Interpol agent Ye Jinbao, navigating antique streets, auction houses, and cultural secrets.

From the capital to the world, he has used his unparalleled talent to blend intangible cultural heritage with technology and fantasy. Amidst political intrigue, business battles, and dialogues between civilizations, he has safeguarded the cultural heritage of China, making the name "Wen Shu Ge" resound throughout the world and writing a legend of civilization protection and global confrontation.

Good news, he's transmigrated to the world of anime! Bad news, no cheat codes! Su Mu transmigrates to a crossover anime world filled with slice-of-life stories, but all he gets is a broken Sword Saint System. The system can provide him with sword techniques from various worlds, but it can't teach him them immediately; he has to learn them through his own efforts. Su Mu practices diligently and eventually becomes a sword master, but the comfortable life of modern society troubles him. No one can challenge him, and he finds amusement in beating up thugs at Soubu High School. Until one day, he obtains an Infinite Flow System, allowing him to transmigrate to different worlds and challenge powerful figures from those worlds. Su Mu has completely opened the door to a new world! *The Failed Knight*, *Black Bullet*, *The Burial of Freeland*, *Ascendance of the Fearless*, *High School DxD*, *DanMachi*, *Type-Moon*, *Honkai Impact 3rd*... From then on, Su Mu's fame spreads throughout various worlds. (Main world mixed with Aoyama Gyoukai, randomly transmigrating to Infinite Flow worlds)
