"It's her for now." Tang Xiao pinched the bridge of his nose, "It would be nice if Princess Changgu's body could be examined, so that we could know if she was poisoned." ”

"There is no need to investigate, so Princess Chang died of poisoning."

"What kind of poison is that?"

"It was checked out by Imperial Physician Zhang back then, and it was said to be arsenic, but the palace was not allowed to have such a poison, so the poison was brought in from outside the palace, and the palace concubines couldn't leave the palace easily, so they should have bought it outside."

"If you find out who went out to buy arsenic, you can know who killed Princess Changgu, but it was more than 20 years ago, so it's not easy to investigate, but even if it's not easy to check, you have to check."

Tang Xiao lowered his eyes and began to figure out how to check.

Thinking about it, my head is going to explode.

Feng Junmo didn't want to disturb her, so he sat quietly aside.

After a moment, Tang Xiao slapped his head.

"There it is."

"What?"

"Find a painter to take the portraits of all the palace maids around the queen, and then take their portraits one by one to the pharmacy and ask."

"This can't be done, it's been more than 20 years, and even people with good memories will forget."

"No, the people who sell medicinal herbs are usually very careful, not to mention poisons, so there should be a record in the pharmacy."

"Well, then I'll make up a reason and ask the painter to go to the palace to paint their portraits."

Tang Xiao leaned over to him, put his hand on his shoulder, raised his eyebrows and smiled: "Lord, then if I wash away the grievances of your mother, how can you thank me?" ”

"How do you think I can thank you?" Feng Junmo raised his eyebrows.

"It's still the same sentence, be gentle with me, don't kill me."

She's really persistent.

This is the condition that is mentioned every time.

Could it be that she is so afraid that he will murder her?

But if she is obedient and doesn't always get angry with him, why would he kill her? You must know that it is not good to be angry too much!

Feng Junmo covered his forehead and let out a long sigh.

"Do your best."

"Hehe, then you go to the painter to paint a portrait of the queen's palace maid, and I'll think about this matter again."

"Yes."

Feng Junmo nodded, then got up and left.

Tang Xiao lay on the table, his right index finger tapped on the tabletop, and the sound of "knock" sounded.

What if I can't find the palace maid who bought arsenic back then by relying on the portrait? No, we have to find another way!

Tang Xiao suddenly had a flash of inspiration, got up and rushed out of the room, running all the way, and finally saw Feng Junmo at the door of the mansion.

Because the weather was too hot, she was already panting and sweating profusely after running for so long.

"Lord Wang, you don't have to go, I thought of another way." Tang Xiao leaned on the door frame, panting.

Feng Junmo was just about to get into the carriage, and when he heard her say this, he asked the housekeeper to park the carriage, and then walked up to Tang Xiao, looking at her who was sweating profusely and panting.

"What's the solution?" Feng Junmo asked.

"It's complicated, and you need to find the king of Zhenbei to join forces." Tang Xiao's cheeks were flushed, as if he had been coated with a layer of rouge, and the white was translucent and red, which was very good-looking.

Tang Xiao knew that the matter of playing tricks on King Zhenbei last time had not been resolved, and he would naturally not be willing to find him this time, but he always had to try.

Feng Junmo took a deep breath.

"Do you think he'll help you? Have you forgotten the last time he came to Xingshi to ask about sin? ”

"What's this, I have a way to get him to help me." Tang Xiao patted his chest and looked at Feng Junmo with a smile, "This matter is on me, I'll go!" ”
