In 1941, as the smoke of war broke out at Pearl Harbor and the war in the Pacific swept across the Southeast Asia, the Japanese army broke through the jungles of Malaya and attempted to annex the entire Southeast Asia. In troubled times, with great waves washing over the sand, the twin Takeda brothers hid in the enemy camp, using flesh and blood as blades and faith as a lamp, retrograde in the abyss of the spy sea.
His elder brother, Takeda Shinichi, joined the Japanese Malayan Corps, swirling around the power whirlpool under Yamashita Fengfumi, and stealing top-secret military information in the shadow of swords; his younger brother, Takeda Shinji, as a doctor of chemistry, lurked in the Nanyang spy agency, using top knowledge to create a secret chemical space and build an anti-Japanese underground fortress. The two brothers are both underground members of the Chinese Red Party. They are far apart from each other, but they cherish the same righteousness of their family and country, and they stick to each other in the bloody storm.
