The constant temperature box contains not spices but animal organs soaked in preservative liquid. Tang 꿦 uses a folding fan to pick up the half-rotten sheep liver, and micro-tattoos emerge under the ultraviolet light: "This is the sacrificial mark in the Luban Book!"
Qin Feng suddenly stuttered and pointed to the ceiling. The thermal imaging showed that the ventilation ducts formed the innate Bagua formation. Su Chen climbed up the shelf and touched the bronze mechanism in the duct - a replica of Zheng He's compass. As he turned, the blue bricks on the ground suddenly cracked, revealing the stairs leading to the underground.
In the center of the secret room, seven ever-burning lamps surrounded the bronze coffin. Tang's compass was completely out of work, so he dipped some lamp oil and drew the hexagram of Lian Yi on the coffin: "Buried in Yin, prospered in Mao, this is an evil magic to change the fortune of Yang by using the Yin house!" Inside the coffin lay the vivid face of Chen's ancestor, holding the Nazi document from 1943 in his hand.

Yellowed documents record a shocking conspiracy: During World War II, the Nazis smuggled looted cultural relics disguised as Zheng He's relics through the network of overseas Chinese in Southeast Asia. Chen's ancestors acted as middlemen and used feng shui secrets to build an underground transportation network, with the Chao Phraya River Pier being the hub at the time.
"Look here!" Su Chen used a nano knife to cut open the sleeve of the corpse, and found a cargo route map tattooed on the crook of the arm - it completely overlapped with the spice transportation route of the contemporary Chen Group. Qin Feng suddenly called up the autopsy report of the frozen Chen Zihao, and the ink composition similar to that of the Nazi documents was detected in the stomach residue.
On a rainy night, three people raided the Chen family's old house. Tang 꿦 used the Five Emperors' Coins to crack the door mechanism, and Su Chen found a secret compartment behind the ancestral tablet. When the bronze compass was inserted into the groove, the entire wall flipped over to reveal a secret room - an optical array composed of thirty ancient mirrors, projecting the reflection of the gilded Buddha onto the jewelry building on the other side of the river.

"This is the real weapon!" Su Chen pointed at the convex lens in the center of the mirror array. After multiple refractions, the sunlight formed a high-temperature focus on the river surface, which perfectly explained Chen Zihao's drowning without water - the focused sunlight instantly vaporized the water in his lungs.
Tang 꿦 pulled off the canvas behind the mirror, revealing the solar calendar time during the Nazi era: "They used ancient astronomical algorithms to calculate the focusing time!" Qin Feng suddenly resumed his fluent speech: "All the dead were born at the time of the solar eclipse, and the moisture content of their skin is abnormal!"
When the police rushed to the top floor of the jewelry building, the real mastermind was debugging the last mirror. The 90-year-old Mrs. Chen turned around, and her face was exactly the same as the frozen corpse: "The anti-time incense allowed you to live for a hundred years... But true immortality requires more sacrifices..."
Tang Xiao threw out the Luoyang shovel to smash the solar calendar, and the uncalibrated mirror array suddenly caught fire. Su Chen used a fire axe to split open the safe, and inside were boxes of anti-time incense - radioactive isotopes covered with agarwood.
When Qin Feng uploaded the evidence chain to the alarm system, the Chen family's old house collapsed. In the smoke and dust, the century-old corpse quickly weathered, leaving only the Nazi documents curled up in the fire.
Three months later, Su Chen stood in front of Zhenghe Pavilion. The pupils of the restored gilded Buddha were no longer red, the golden signboard of Tang 꿦's fortune-telling stall swayed in the sun, and Qin Feng delivered the latest autopsy report - all the "freezing age" effects were caused by radiation diseases.
The rainstorm came suddenly, washing away the century-old conspiracy. When the first ray of sunlight penetrated the clouds, the three people disappeared in the fireworks of Chinatown, and a new case was quietly growing in the morning mist...
