Happy Palm: The War King's Favored Little Doctor Consort

"Su Qingli, what do you mean?" Marquis Qingyang felt vaguely uneasy.

"What I mean is that the murderer who killed the lady must be someone close to her who knew her very well." Su Qingli walked forward and grabbed Xu'er's hand. "Miss Xu'er, why are your hands shaking so badly?"

"You killed my wife, I'm afraid..."

"Are you afraid that I will kill my wife, or are you afraid that if you cut your finger you will also be poisoned and die?"

Xu'er was so frightened that she stammered incoherently: "You're talking nonsense, I...I didn't do that."

Su Qingli ignored Xuer's sophistry, but looked at everyone and continued speaking.

"The wife of the Marquis of Qingyang has been poisoned by a type of poison called Naraku. This poison is very special. It is harmless when taken orally, but it becomes highly toxic if it comes into contact with blood. It will kill her in a matter of minutes."

"Naraku is colorless and tasteless, but when it comes into contact with the juice of purple water lily, it will turn light purple." Su Qingli took out a piece of grass, "This is the purple water lily I found in the weeds in the Qingyang Marquis's mansion."

Su Qingli handed the purple water caltrop to Xuanyi: "Take a basin of clean water and drop the juice of the purple water caltrop into the water."

Xuan Yi dripped the juice of purple water caltrop into the water and looked at Su Qingli.

Su Qingli grabbed Xuer's hand and dipped her hand into the basin. After a while, Xuer's hand was stained with a layer of light purple.

"Okay, so you are the murderer of my lady!" Marquis Qingyang pulled out the guard's knife and chopped it, as if he wanted to kill Xu'er.

Xu'er was stunned and forgot to react for a moment, while Xuanyi grabbed the wrist of Marquis Qingyang and pushed him away.

"My Lord, please be patient. Just because this girl's hand is poisoned doesn't mean she is the one who poisoned it." Su Qingli put her own hand into the water, and soon, her hand was also stained light purple.

"Everyone, look, my hands are also stained with poison." Su Qingli said slowly, "It's not that we are the murderers, but this maid and I have touched the poisoned items."

"What item?"

"Today, I only touched one thing in Madam's room: a chess piece."

"You mean, the chess piece I gave to Madam is poisonous?" asked the Marquis of Qingyang viciously.

"Yes, sir."

"Ridiculous! How could the chess piece I gave my wife be poisonous?" As he spoke, the Marquis of Qingyang grabbed a chess piece and threw it into the basin. The piece did not change color. "It's obvious that you and this maid worked together to poison my wife!"

"My Lord, what I'm saying is that the chess game my wife and I played this morning was poisonous." Su Qingli said slowly.

"This is the chess set you used this morning. This is the only set in Madam's room!"

Su Qingli shook her head: "Madame Qin, do you remember when I was playing chess with Madam this morning and I accidentally dropped a chess piece?"

"I remember it seemed to have fallen into the couch, but I didn't pick it up at the time."

The expression of Marquis Qingyang changed instantly. He had never imagined that due to a mistake, a chess piece would be left at the scene!

"If this chess set is the same one we used this morning, then there should be one piece missing, but this one has exactly the same piece missing."

Marquis Qingyang's forehead was covered in cold sweat. He suddenly snatched the knife from the guard beside him and rushed towards Su Qingli: "Quibbling, you killed my wife, give me your life!"

Xuan Yi kicked the Marquis of Qingyang away, and two Xuanyi guards pinned the Marquis of Qingyang to the ground. Seeing this scene, everyone became even more afraid to speak.

Su Qingli glanced at the Marquis of Qingyang and took out a chess piece. "I found this chess piece from under the Madam's couch. Guard Xuanyi can testify to this."

Su Qingli threw the chess piece into the basin, and soon the chess piece changed color.

Everyone was immediately filled with sighs. Who could have imagined that the Marquis of Qingyang, who loved his wife so much, would actually set up such a vicious plan and poison her on her birthday?
