On December 25, 1941, Hong Kong fell. The emergency room of Donghua Hospital was filled with blood, and wounded soldiers from the 38th Division of the Japanese Army filled the corridor. Chen Xi's scalpel had just cut open a major's chest when the head of the Special Higher Education Course pushed open the door and handed over a blood-stained photo: "Have you seen this person?" The photo showed an underground party liaison officer who would be executed in three hours. Chen Xi's face didn't change color, and his fingers moved accurately inside the abdominal cavity. When the last stitch was stitched, a microfilm slipped into the drainage tube - it was the latest defense map of the Hong Kong and Kowloon defense lines. Under the operating light, Japanese Colonel Matsui Taichiro stared at his hands: "Doctor Chen, I heard that you can snatch people from the hands of the King of Hell?" Chen Xi took off his bloody gloves: "Colonel, I only snatch people who deserve to live." That night, three anonymous intelligence reports were sent from different departments of the hospital. The explosion of the gendarmerie warehouse, the poisoning of pseudo-government officials, the modification of the guerrilla ambush route - all clues point to a scalpel that has never missed. Matsui was furious and set up a deadly trap: If the "spy doctor" could not be found within three days, he would kill all the medical staff in the hospital. And Chen Xi's next target is on Matsui's own surgery appointment sheet.
