There was a story about a skilled blacksmith who first forged an extremely sturdy cage and then forged an equally sturdy iron lock.
Then, he walked into the cage that he had forged and carefully felt its sturdiness. The lock that was hung on it suddenly fell down.
He was locked inside. Because his shop was relatively remote and his business was not very good, when he was discovered by others, he had already died of thirst or starvation.
The Japanese priest in front of him was just like the blacksmith in the story. He carefully built the iron cage and the Iron Lock, and in the end, he was the one who was locked.
The priest was different from the young man who had his head broken by Bai Yingying upstairs. He was a bit more advanced and had a stronger endurance.
Because of this,
he still had a part of his rationality.
