The protagonist's halo-terrifying indeed.

Pass it on to more people, and let Lingnan's arcades forever 'fill the streets with commerce'!" That winter solstice, Muhammad returned to Chen Jialuo's Tomb in Hangzhou with a miniature Manchurian window and stained-glass pattern ornaments. Beside the Silk Road Heritage Stele, another new token was added-the pillar-and-window pattern on the Manchurian window, interwoven with tokens such as Lingnan stained glass, Southern Fujian red bricks, a tea basket from the Tea Horse Road, and a Dunhuang silk handkerchief, like a "picture of global civilizations coexisting along a commercial street." Watching a replay of the arcade pattern festival through his AR glasses, Di Yun said with a smile, "From snowy mountains to commercial streets, our heritage really has woven the world into a 'pattern trade network'!" Muhammad opened the Global Pattern Digital Platform. On the screen, a video was playing of A Jie helping tourists identify arcade pillar patterns, captioned: "We are all the arcades' 'street guardians,' and guardians of global patterns too!" Winter snow from West Lake fell on the miniature Manchurian window, while Leifeng Pagoda stood in the snow in the distance, bearing witness to this passing down of heritage that crossed mountains and seas and connected commerce and trade. Muhammad knew that wherever his next stop might be, the moral principles of A Deadly Secret, the keen edge of the Hu Family Saber Technique, and the warmth of global patterns would, like the spiral columns of Lingnan's arcades, forever turn, forever guide the way toward the intermingling and coexistence of human civilizations, and continue writing new cultural chapters that would never end. A new chapter of A Deadly Secret: the coexistence of ring patterns and carved decorations in Hakka tulou (traveling with Hu Fei). Half a month after the Lingnan arcade pattern festival closed, Muhammad received an invitation from the Fujian Longyan Hakka Tulou Protection Association-they hoped to revitalize the "Tulou Ring Patterns" and "Carved Door Decorations" in the tulou settlements. These patterns, engraved on the tulou's outer walls and carved into the wooden components of their gateways, held the Hakka people's clan wisdom and defensive philosophy: the concentric lines of the "Tulou Ring Patterns" symbolized "clan reunion," with each ring corresponding to one layer of the tulou's structure and carrying the implication of "layer upon layer of protection"; the "Carved Door Decorations," meanwhile, expressed wishes for "the family's peace and health" through auspicious designs such as pines and cranes or bats, and some carvings even concealed codes indicating the locations of defensive mechanisms. Yet most of the younger generation now lived scattered across cities and had long since lost the ability to read these "codes within the buildings." When Muhammad invited Hu Fei to join him, Hu Fei was studying the colored patterns on the miniature Manchurian window. Hearing the invitation, he smiled and said, "In Lingnan, saber light reflected in stained glass. At the Hakka tulou, it's time to let saber light reflect in ring patterns. Let's see whether concentric circles can 'stand guard together' with saber techniques!" When the convoy arrived at the Yongding tulou cluster, Uncle Zhang, a researcher of Hakka tulou, was already waiting in front of Chengqi Lou. Pointing at the "concentric ring patterns" on the tulou's outer wall, he said, "In this building's 'Three-Ring Guardian Pattern,' the innermost ring is the ancestral hall, the middle ring is the clan's living quarters, and the outer ring is the defensive works-the thickness of each ring corresponds to a different degree of protection; as for the 'pine-and-crane carvings' on the gateway, the spot toward which the crane's beak points is the concealed door to what was once a lookout opening. But how would children these days know how to read clan stories in the ring patterns?" Hu Fei looked up at the tulou's concentric outline, his saber reflecting the curves of the ring patterns. "The 'Ring Formation for Repelling Enemies' form of the Hu Family Saber Technique emphasizes 'letting the saber follow the ring's turn, attacking within defense.' The layout of these Tulou Ring Patterns looks like a natural 'saber formation diagram'!" One, the defensive fusion of martial arts and tulou patterns: letting saber light "guard alongside the rings." Working with Lin Xiaowu, Hu Fei combined the agility of Lingnan's "Arcade Pillar Step" with the steadiness of Southern Fujian's "Swallowtail Ridge Step" to devise the "Tulou Ring Formation Step": guided by the concentric paths of the "Three-Ring Guardian Pattern," the youths were to walk along the ring patterns in the tulou courtyard, slowing their steps in the inner ring (the ancestral hall area) and gently raising both hands (symbolizing reverence for their ancestors), then advancing steadily through the middle ring (the residential area),
