The Spy's Deadly Poison

No System, no pocket dimension. The protagonist knows a little traditional Chinese medicine and is highly skilled in pharmacology. Becoming a top agent takes more than personal ability; luck is essential too. Mu Yunping is just such a legendary agent. He first joins the Military Statistics Bureau, then infiltrates the No. 76 secret service organization as a spy, and eventually joins the underground Communist Party. With these three identities, he plays a unique role in the War of Resistance against Japan.

Mu Yunping may not be much of a fighter, but he is exceptionally clever and can always come up with an unexpected way to defuse a crisis. With the full support of the members of his undercover team, he leads them in completing one mission after another with distinction, making an indelible contribution to the fight against the Japanese invaders.
