Transmigrating With Two Garen Copies

Volume One: Surviving in Chang'an (Chapters 1–50): The two Galens adapt to life in the ancient world. Using his accounting skills, they help one of Su Chengye's subordinates sort out a chaotic military supply ledger and uncover a loophole where provisions are being skimmed. With meticulous handwork, they help a talisman cultivator draw low-grade talismans, solving the problem of wasted talisman paper and catching Su Chengye's attention for the first time. They enroll in Chang'an's lowest-tier institution, the Chang'an School of Calculation, a fringe establishment that combines mundane studies with cultivation, and begin exploring the path of the “calculation cultivator.”

- Volume Two: Making a Name (Chapters 51–150): They join Su Chengye's household as his accountant, using modern accounting methods to reform its finances and close loopholes exploited by corrupt confidants installed by powerful clans. In the “Chang'an Supply Allocation Case,” they use a cost-benefit model to predict that the grain route will be attacked and change the transport route in advance, saving vital supplies. Meanwhile, they cultivate “calculation essence,” learning to control it precisely with both hands and draw low-grade talismans with 30% greater accuracy, attracting the attention of fringe powers in the cultivation world.
