The crowd searched around the ruined temple and found that apart from a few wild dogs, there were no signs of human entry.

Just then, a guard discovered something near the puddle ahead.

"Miss, there is something going on here."

A guard squatted down and picked up a few pill residues on the ground that had not been melted by the rain with the tip of his knife.

Qin Jiuge followed closely and squatted on the ground to examine it carefully. The dark red pill had become very light in color after being soaked. But it was still recognizable that it was not an ordinary pill.

She took out a silk handkerchief and wrapped it carefully, "Take it back and give it to the imperial physician for examination."

…

Back at the princess's residence, Chu Qingluan was reading the secret report. When she saw Qin Jiuge coming in, she asked without even raising her head, "How is it?"

"Princess." Qin Jiuge took out a silk handkerchief from her bosom and unfolded it. "The situation is more complicated than I thought. The Imperial Hospital has verified the drug residue and confirmed that it is Dingjing Powder."

Dingjingsan, on the surface, is a medicine for women to calm the nerves and soothe convulsions, but in fact it contains blood-breaking ingredients such as musk and saffron, and can be used to kill people in a covert way.

Chu Qingluan tapped the table lightly with her fingertips and suddenly asked, "Where's Yun Yan?"

"Still locked up in the woodshed, crying out that he was wronged..."

Having said this, Qin Jiuge suddenly paused, and an important clue suddenly came to his mind.

"Princess, I'll go to the woodshed right now." After she said that, she turned around and said goodbye, without even waiting for Chu Qingluan's instructions.

Meanwhile, in the backyard woodshed.

With a "bang", Qi Che shouted that he was tired and was about to sit down to rest for a while, when suddenly the door was kicked open from outside.

Qi Che was startled at first, and subconsciously glanced at the haystack not far away.

Under the haystack, there was a pile of hay stained with red soil.

Qi Che's pupils shrank suddenly, but he quickly returned to his cowardly look.

"Ms. Qin, what are you doing..."

Qin Jiuge strode forward with a cold face, his eyes fixed on the tip of his shoes.

"Someone, take off his shoes for me!"
