Bottom Line 72 Hours

Retired agent Lu Xiao, who was once a sharp sword for national security that made enemy agents frightened, now exiles himself in the shadow of the port warehouse, letting his sharp edge become dusty. When the most dangerous foreign mercenary organization "Viper" extended its claws to the country's energy lifeline, a shocking conspiracy against the LNG receiving station quietly detonated within 72 hours. No backup, no intelligence, just an old wound and a rusty dagger. The ghost codename "Dark Blade" of the past is dead, and only "The Bottom Line" is reborn. This is a race against time, and a desperate fight to death. He must prove that even the dullest knife can cut through the deadliest snake.
