Yun Shang fell silent and frowned. She thought to herself, 'this is for Xia Houjing. Why did he save NING Hua Jing after he killed Xia Houjing? More importantly, who is he?'
Emperor Ning also had a long face. He waved his hand and said, "go back to the palace with me, the head of court of justice."
The head of court of justice answered yes immediately and followed emperor Ning out of the prison. Yun Shang and Emperor Ning rode together, and the head of court of justice followed them on a horse.
"In your opinion, where should we start?" Emperor Ning got on the carriage. He frowned and asked in a low voice.
Yun Shang thought for a while and said gently, "We should start on the oil."
Yun Shang said as emperor Ning looked at her. "In general, the oil is an extremely luxurious thing for the ordinary families. They won't buy too much. Besides, in some rich families, it doesn't smell well, and the lights and oil used are added with good aroma. Xia Houjing was caught in prison by surprise, so was my sister. If the culprit wanted to buy so much oil in such a short time, there should be a lot of traces of it. Although it might be done on purpose, it could still be a clue. "
Emperor Ning didn't speak. Yun Shang thought for a while and added, "what we need to investigate as well is the guards and guards in the prison. The lock of sister's cell is complete. There is only one explanation: the key to her cell is on the culprit's body. Only the guards have the keys to the rooms. Even if it were not them, someone must have taken the key from them. "
Emperor Ning nodded, "there are many traps in the prison, but they are

They kept silent for a while. Prince Jing glanced at the scroll on the table and said, "are you looking at the documents in the prison?"
Yun Shang nodded her head, "I want to see who built up the prison. I want to know who is in the prison too." No matter what happened, it meant that the man was very familiar with the prison and its triggers.
"The creator of the prison..." Prince Jing frowned. "It's said he is a very famous person. But he doesn't seem to be a citizen of the state of Ning."
The creator of the prison was not from the state of Ning? Yun Shang frowned, having no idea what this had to do with the fire incident.
"By the way, after you left, I found that the cooking oil was too much and the smell of it could be long-lasting. I feel a bit strange. Let's go to prison together later and have a check." Yun Shang said gently.
Prince Jing nodded his head and remained silent for a while. Then he said flatly, "after this matter is settled, you go to the state of Xia with me."
