There are three strange cases in Beijing, with lock marks on the heart and mouth, killing people silently, and it is said that they are caused by evil spirits.
Ou Junsheng, an official from the Ministry of Justice, went into a deserted alley alone and found an ancient black iron lock in a century-old craftsman's workshop. Only then did he realize that the so-called evil was just a big lie that had been told from generation to generation.
A lock is not a life-stealing tool, but a tool to suppress evil; a person is not innocent, but a greedy and delusional person.
He entered the game as a loner, but in a desperate situation, he met a woman in plain clothes who showed mercy.
She had a silver needle in her sleeve, a secret in the world between her eyes, and a pure body, yet she walked through the wind and rain with him and passed through the mountain of knives.
The lock keeper has been guarding the secret for hundreds of years, the Black Evil Gang has been chasing the lock for ten years, the old grudges of the Craftsman Sect, and the poison of the troubled times are all entangled with this ancient lock.
It turns out that what was waiting for this century-old puzzle was never someone who was greedy for power and profit, but someone who had no distracting thoughts and dared to expose right and wrong.
The lock recognizes the master, the situation is restored, and we stay together through thick and thin, and finally see the light of day.
From now on, there will be no evil in the world, and peace will last year after year.
Intention: Those with a right heart can eventually overcome the situation; with sincerity, we can exchange for clarity in the world.
