Redscale: The Intelligence War of the Three Kingdoms

Lu Chen, a modern intelligence specialist, unexpectedly transmigrates into Xuchang in the fourth year of Jian'an and becomes a covert operative under Cao Cao, code-named “Shadow Scale.” As the bloody storm of the Edict of the Belt sweeps through the capital, he forges crucial evidence using his original “three-way intelligence verification method” and manipulates the couriers carrying secret messages with microexpression psychology. From the Eight Formation Diagram cipher to a covert operative training system, he plants the seeds of division in Cao Cao's camp on the eve of the Battle of Guandu. In the end, he helps bring about the first Intelligence Pact of the Huai River between the states of Wei, Shu, and Wu. See how this intelligence analyst uses modern thinking to rebuild the rules of a chaotic age. In this war without smoke, blades glint in the ink on bamboo slips.
