Although the prince is not in good health, there is more than one son! As long as he becomes the emperor and sets up another crown prince, the king of Han can only look at the throne and sigh!

Therefore, the return of His Majesty's army to Beijing this time is the best opportunity!

Bai Tang closed his eyes: Qin Ling! You're here! If it weren't for you, who could have calculated that His Majesty would die on the way back to Beijing and lay such a meticulous trap?

Just, why would you do that?

The prince's face became solemn, and the itch on his fingertips became heavier, and he had to run his fingernails through his fingertips.

Qin Xuan asked urgently, "Did Bai Tang find anything?" ”

Bai Tang stared at the prince's finger: "Originally, no, now...... Your Highness, what happened to your hands? ”

The prince couldn't help but spread out his palms, revealing palms of varying shades of color and peeling flakes.

Qin Xuan was taken aback, and hurriedly called the imperial doctor, while blaming the prince: "Why didn't you call the imperial doctor earlier when you were not feeling well?" ”

The prince was also wronged: "It was fine a few days ago, but today it's suddenly like this!" ”

Judge Lu hurriedly came, and as soon as he saw the prince's hand, his face turned grim: "What has Your Highness touched recently?" Have there been any greenery, spices, or other additions to the temple? ”

The prince and the palace people thought hard for a long time, and shook their heads together: "No." ”

Lu Yuan's verdict was cold-faced, and after confessing the crime, he immediately called several colleagues to search the prince's living room.

Qin Xuan asked in shock: "Doctor Lu, could it be that the prince he-"

"Hmm." Doctor Lu gritted his teeth, "Poisoned!" ”

The prince was shocked and frightened when he heard this: "Poisoning?!" ”

"Your Highness, rest assured!" Doctor Lu hurriedly said, "Fortunately, I found it early!" Chen will help you prepare the antidote immediately! ”

Qin Xuan was furious, and he actually put the poison into the East Palace! Fortunately, Bai Tang is awake! couldn't help but look at Bai Tang, but saw that his face was as heavy as water, and a pair of wonderful phoenix eyes were completely condensed into ice, and the forest was terrifyingly cold!

Half an hour later, the prince had already drunk a bowl of antidote.

Doctor Lu was reported: "No suspicious things were found in the prince's palace!" ”

Doctor Lu stared at several medical officers in disbelief: "Impossible! ”

The medical officers bowed their heads and said, "Lord Lu, I really haven't found anything poisonous!" ”

The crown prince and Qin Xuan couldn't help but look at each other!

Doctor Lu flicked his sleeves and went into battle in person!

It was more than half an hour, and Doctor Lu came back with a disgraced face.

Qin Xuan was furious: "Even you haven't found it?" ”

Doctor Lu closed his eyes: "The toxicity of this substance is quite strange!" It was obviously caused by His Highness's exposure to some poison. But the minister tried his best, but he never found the source of the poison! The minister is derelict in his duties, and the minister is worthy of His Highness's trust, and he is ashamed of the hospital! ”

The prince was quite calm, and waved his hand: "The person who uses poison is cunning, what is the crime of Imperial Doctor Lu?" He searched the hall and fixed on Bai Tang's body: "Bai Tang, you are well-informed, how can you know that Gu is poisoned?" ”

As if Bai Tang had woken up from a long slumber, he looked at Xu San beside him, and then at Doctor Lu, and after a long time, Fang said with some difficulty: "Your Highness, you asked Master Ban Zhi to treat your leg disease before. Has the Guru ever ...... What is left for you? ”

The prince was stunned and confessed a few words to Doctor Lu.

Doctor Lu quickly took two volumes of medical scriptures from the prince's bedroom.

"Does Gongzi Lian suspect that there is something wrong with this medical scripture?" Doctor Lu is very confident in Ban Zhi's medical skills and character, "I have also examined these two volumes of medical scriptures, and there is nothing unusual!" ”

Bai Tang looked at the dark yellow medical scripture that was obviously many years old, and many ice arrows shot out in his phoenix eyes!

Panchi!

It's not good to be his miracle doctor and holy monk, and when he is full, he runs thousands of miles to the capital to murder his grandson? ! He's really tired of being crooked?!

Faintly, he had a hunch that Ban Zhi's behavior was probably inseparable from Qin Ling!

"Baitang?" Xu San tugged at his sleeve. "Imperial Doctor Lu is talking to you!"

Bai Tang took a long breath, raised his head and met Doctor Lu's suspicious eyes: "Imperial Doctor Lu, below is the shopkeeper of Songzhu Zhai, who has to be promoted by his peers, and has a slight reputation in the engraving industry." ”

Imperial Doctor Lu smiled: "The old man knows!" ”

Bai Tang stepped forward and picked up a volume of medical scriptures: "The paper under this world, no matter how light or expensive, Bai Tang has a lot of experience." ”

Doctor Lu Tai's chin bowed: "Songzhu Zhai's Korean paper, the recent magnetic green paper, are all paper intermediate products. ”

"Magnetic green paper-" Bai Tang smiled bitterly, "His Royal Highness the Prince." The Gao family in the city worked hard to make magnetic green paper, and asked me. I showed him the way. Tell him that the magnetic blue paper may have been lost in the Central Plains, but in Wusizang, because Princess Wencheng entered Tibet, there may be a legacy! ”

Imperial Doctor Lu was puzzled: "This ...... What does it have to do with this medical scripture? ”

"Imperial Physician Lu. The papermaking technique of Tibet was started by Princess Wencheng's entry into Tibet. The paper used in these two volumes of medical scriptures is the unique paper of Wusizang - Tibetan paper. ”

Hearing this, Imperial Physician Lu couldn't help but look at the medical scriptures twice.

"Tibetan paper is thicker and tougher than the paper in the Central Plains." Bai Tang took the Korean paper before the prince's case and compared it, and the Tibetan paper was a little thicker than the Korean paper!

"The materials used to make paper are always adapted to the right place. After years of exploration in Tibet, local plants such as angelica leaves, agarwood, and dogwood have become the main materials of Tibetan paper. ”

Imperial Physician Lu was a little dazed when he heard this: "You have been talking about Tibetan paper for a long time, what do you want to say?" ”

Bai Tang said with a straight face: "Imperial Doctor Lu, please listen to me." ”

Among them, Tibetan paper with wild camellia trees as the main raw material is the top quality. Paper with agarwood as the main raw material is medium grade. However, all the important scriptures of Tibet were written on paper made of inferior materials! ”

Doctor Lu and everyone were puzzled: "Why is this?" ”

"Because the main raw material of inferior paper is a plant called Ruixiang wolf venom!" Bai Tang spit out the words "Ruixiang wolf venom", and he couldn't help but think of clusters of white flowers and red paths, beautiful but with deadly toxins! "Paper made from this raw material is inherently toxic! Insects and ants do not invade, it is not easy to corrode, and it can be stored for thousands of years! ”

Doctor Lu had never been to Uszang, nor had he heard of this plant, but when he heard its name, he felt that it was so poisonous: Ruixiang Wolf Venom - a beautiful and fragrant poisonous flower as fierce as a wolf!

Xu San understood: "You mean-the paper transcribed by these two volumes of the Medical Scripture is made of Ruixiang wolf poison?" ”

"Yes!" Bai Tang put down the medical scriptures and asked for a basin of water to wash his hands carefully. "Do you want to come to Master Panzhi to wash his hands after he has finished treating His Highness?"

The crown prince and Doctor Lu nodded silently. Ban Zhi applied medicine and massaged the prince, and it is very normal to wash his hands afterwards, and no one will suspect that the medical scriptures he brought are poisonous!

"Normal people are physically strong, and occasional contact with wolf venom paper is not too much of a problem. But His Highness is different! Bai Tang couldn't help but praise the mastermind after the incident, "The prince is weak, and he has allergies and poisoning reactions after a little contact. If you are exposed to it for a long time, the toxin will invade your body—"

With the prince's body and bones, don't even think about saving it!
