The imperial doctor nodded: "Yes, it has been half an hour."

Gu Nuo'er looked at Ling Tianyin's face, she stepped forward and tried to get Ling Tianyin's pulse.

The imperial physician said loudly, "Your Highness, if your majesty has another accident, can you afford this responsibility?"

Gu Nuo'er didn't look at him, just lightly pressed on Ling Tianyin's pulse.

The girl's face is cold and charming.

Her voice was cold: "I'm all here, what do you think is the responsibility that I can't bear?"

The doctor was speechless.

Gu Nuo'er calmed down and felt Ling Tianyin's pulse.

Fortunately, she has been learning some medical skills from her third brother, and even without mana, she can still tell whether a person's condition is good or bad.

The poison in Ling Tianyin's body was not severe, it could even be said to be a sudden illness.

It seems that the poisoner only started today.

Gu Nuo'er put Ling Tianyin's hand back into the quilt gently after knowing it.

Prince Yun Linzhou has already brought his courtiers in.

Along with them, there was Queen Lu who heard the news and came to visit.

"Your Majesty!" Empress Lu hurriedly sat down on the edge of the bed with a worried face, holding Ling Tianyin's hand tightly.

Yun Linzhou's tone was calm enough: "Since the mother is here, my son will explain the cause and effect in front of everyone at one time."

"This evening, the father suddenly vomited blood while drinking the medicine, and then fell into a coma."

"After the imperial doctor came to diagnose and treat, he found that the father was poisoned."

Empress Lu looked at him with tears in her eyes: "But what does this have to do with Nuo'er?"

Yun Linzhou handed over his hands and replied, "My son asked the Imperial Hospital, these days, the father and the emperor have asked the Imperial Hospital to decoct the medicine according to the prescription prescribed by the princess."

"Three times a day, it doesn't fall. After the imperial doctor's examination, there is a medicine in this prescription, which is in conflict with the state of the father's dragon body."

Empress Lu hurriedly asked, "What medicine is it?"

Yun Linzhou raised his eyes to look at Gu Nuoer, and he said word by word, "Dragon bone grass."

Gu Nuo'er did not change her face, but her eyes were clear but suddenly darkened.

It turned out to be waiting for her here.

Empress Lu looked surprised: "Dragon bone grass? What is that?"

Yun Linzhou turned to the queen and said, "After Qingge became seriously ill, the princess, as her friend, sent a lot of dragon bone grass from Daqi to treat her disease of leaving the soul."

"But everyone should not know that if the dragon bone grass is used by unsuitable people, when the amount is huge, it is enough to be comparable to arsenic poison, which will make people swell with blood and die suddenly."

Master Kou, who had just been slapped by Gu Nuoer, immediately pointed at Gu Nuoer and yelled.

"You thief girl who came here, how dare you try to murder the emperor, and waste the emperor and the queen's trust and favor with you!"

Gu Nuo'er gave him a cold look: "I didn't poison."

Mr. Kou threw his sleeves and sneered with his hands behind his back: "There is no basis for what you say, the evidence is conclusive, but you, who can coax the emperor to drink the poison as a life-saving medicine?"

Gu Nuoer calmly took out a piece of paper from her arms.

Her dark eyes are smart, her complexion is white, and she is strong and unyielding.

"When I wrote the prescription to the emperor, I specially used copy paper, that is, two pieces of paper stacked on top of each other to write, his one, and I keep one."

Yun Linzhou's eyes darkened.

Gu Nuo'er calmly pointed to the pamphlet brought by the imperial doctor and said, "Just compare my handwriting with the two pairs and see if there is a medicine such as dragon bone grass in it, and then you will know whether I have been poisoned."

Master Kou was still shouting fiercely just now, his eyes flickered with astonishment, and he glanced at the prince from the corner of his eye.
