In Shanghai during the Republic of China, the cold-faced officer Chu Xiao was ordered to track down the "Gunpowder Ghost", but he encountered a ridiculous scene of Shen Zhihan, a doctor of chemistry, cooking noodles in a beaker. The muzzle of the gun is pressed against the chin, and the smell of gunpowder smoke surrounds the food:
"Is cooking noodles like dynamite?"
"It tastes stronger than bullets."
The cat-and-mouse game suddenly turns into a fatal attraction. When the Japanese army launched an inhumane germ warfare plan, Shen Zhihan put on a mask and transformed into the famous actress "Han Yu". His sleeves flipped and poisonous wine poured into the enemy's cups. During the curtain call, Chu Xiao pressed him against the makeup mirror and whispered:
"Every singing sound is like calling my name..."
Laboratory utensils reflect cold light, and stage rouge hides murderous intent. He calculates his way out in equations, and he plots his way back with gunfire.
——Beakers collide with bullets, and smoke and roses burn together. Two souls use love as a blade in the broken mountains and rivers to write the most ardent formula to save the country.
Purpose: Scientific rationality and iron-blooded romance collide in the national tragedy, tempering the immortal spirit that protects the mountains and rivers.
