Spy war + official intrigue + undercover.
When an officer who suddenly wakes up begins to truly become a sharp blade in the heart of the enemy camp step by step, his legend is also being written step by step. You can have fame, you can have profit, you can have women and beauty, you can have intelligence, you can have many friends, you can have a few enemies. A different intelligence agent, a different top agent, code-named "010" is writing a legend step by step.
