Not long afterwards, Queen Seondeok decided to take a walk with her officials on the Namsan Mountain. When he heard of it, Kim Yushin made a pile of dry logs and twigs in the garden outside of his house and set it on fire for the Queen to see. High up on the mountain, the Queen noticed the black smoke that was coming from Yushin's residence area, and asked those accompanying her if they knew the reason. No one dared to answer her, but simply looked at one another in embarrassment. When the Queen pressed on the issue, she finally learned from them about the rumor of Munhee's pregnancy out of wedlock and that Kim Yushin might burn her to death because of it. She was astonished with what they said and wondered "Who could the father be, to make Kim Yushin act like that". She then noticed the anxious look on Kim Chunchu's face and asked if he knew anything about it. After the truth was revealed, the Queen ordered him to go and save Munhee's life by granting him the permission to marry her as his second wife, to become his lawful spouse when his first wife died.
