▸ The ledger is stuffed into a red lacquered bamboo tube (mainchain anchored)

▸ Detailed accounts are torn into hundreds of golden slips (transaction splitting)
▸ Seal corner cover pepper pattern bite arrow mark (anti-counterfeiting certificate)

Suddenly, a sharp whistle came from downstream! The tax collector's patrol boat intercepted the skiff: "No official seal on the note, false account!" Cui Suanpan sneered and threw out a swan feather verification dart. The tip of the dart pierced through the note, and the ink actually revealed a phantom: the tax collector's fingerprints from last night, which altered the rice amount, were exposed in the light and shadow. "I’ll deduct three boat’s feet fee from you!" The tax collector retreated, covering the back of his hand. This move is called the fraud revelation technique.

The heavy rain flooded the official sluice. The governor's inspection ship was stuck in the mudflat, while the grain officials from various states were exchanging silver at the teahouse using the #Arbitrum water sign. The floating mortise and tenon pattern on the card displays in real-time:

"Songjiang Prefecture Fire Expense Silver 47 taels"
"Changzhou Prefecture is exempt from waiting for three days"

The most astonishing is that #Arbitrum abacus – it hangs from the beams of the teahouse, untouched by anyone yet ringing day and night. Sparks fly between the beads, scorching the blue bricks with tomorrow's grain price trends. The grain officials observe the scorch marks and adjust the ships: "This is ten miles faster than waiting for the governor's approval!"

Ritual manifestation

Key operations must present the "ARB" light and shadow text
When fraud is exposed, one must drink: "ARB reveals the truth!"

Five years later, the river channel is silted. The new governor prohibits private transportation, #Arbitrum 水牌被熔成铜锭。崔算盘临刑前夜，百船汉子将 # Arbitrum's flag is soaked in tung oil, rolled into a fuse and buried in the silt.

On the Suzhou dock tonight, old tea drinkers can still hear strange sounds — when the freighter's whistle startles the water birds, the sound of an abacus comes from beneath the mud. Tung oil seeps out from the cracks of the bluestone slabs, gathering into the shape of a beast's head in the moonlight, only to be swept away by the waves.

The grain officials said that is the soul of #Arbitrum calculating the tidal accounts. The bamboo tube of the mainchain is still drifting in the canal, while the soul of the dark paddle has already swum into the Pacific cable, continuing to split accounts and notes at the bottom of the sea.
