The palace at night is shrouded in darkness, this majestic palace, high red walls, dark shadows at night, even more people feel that the copper wall is ironclad, and it is difficult to fly. The sky above me was starless and gloomy, as if it was going to rain.

The dead leaves of the begonias in the courtyard are blown everywhere by the wind, and when you step on it, you can clearly hear the sound of the leaves breaking. A few bamboo poles in front of the window are swaying, and the bamboo leaves are rattling.

In the middle of the night, the wind and bamboo knock on the autumn rhyme, and the thousands of leaves and thousands of voices are love.

In the Daming Palace, Tang Xuanzong, who was about to go to bed, had already taken off his clothes, and was holding his favorite concubine Wu Huifei and teasing, preparing for a battle of clouds and rain and close-quarters.

Suddenly, a hurried, hurried eunuch burst in.

"Your Majesty, Dali Temple Lieutenant Chi Zhenjin, I want to see you late at night", the eunuch hurriedly said.

"The damned Yu Chi Zhenjin won't let me rest well. Little baby, obediently here, wait for me to come back!"

"I know, Your Majesty, the concubine must wash the incense, waiting for Your Majesty. ”

............

"What? It's really nonsense", Tang Xuanzong sat on the dragon chair of the Zichen Hall with an angry face, and his body burst out with a majestic and arrogant momentum, and asked angrily, "Where did you get this news?"

"Your Majesty, this is what my subordinates of Dali Temple have discovered, every sentence is true, please ask Your Majesty to learn clearly", Yu Chi Zhenjin almost didn't catch his breath, and said with a panicked expression.

"Who is this person next to you?", Tang Xuanzong asked strangely. There was a young man who looked like a guard standing next to Yu Chi Zhenjin, who was brought in by Yu Chi Zhenjin, and he didn't say a word since he came in, I don't know what Yu Chi Zhenjin brought him for.

"This, Your Majesty. He is an ordinary temple in Dali Temple, just a six-grade official", Yu Chi Zhenjin heard Tang Xuanzong ask about the man he brought, his heart was almost to his throat, and after thinking about it again and again, he still did not say the true identity of this person.

"It's just a Dali Temple, you dare to step into the palace hall of the Tang Dynasty, Yu Chi Zhenjin, the people you bring are not small", Tang Xuanzong shouted angrily.

"Your Majesty, although he is an ordinary temple, he is thoughtful, and this news is what he analyzed", Yu Chi Zhenjin secretly swallowed a mouthful of saliva and continued, since he didn't debunk him just now, then there was no need for it after that.

"Joke, my Luoyang royal family, more than 1,200 people, including me, almost everyone drinks tea from Qingxin Tea House. If the Pure Heart Tea House really intended to kill me, I would have died long ago. Moreover, why do you think that Qingxin Tea House will be the real culprit behind the scenes", Tang Xuanzong still didn't believe what Yu Chi Zhenjin said, and asked the young man.

"Weichen, when Weichen first knew, he also felt that this was unbelievable and unbelievable......"

"It's a bunch of clichés, I don't want to listen to these useless things, get to the point. Moreover, I am asking him, not you, don't interject", Tang Xuanzong directly interrupted Yu Chi Zhenjin's words, and continued to ask the young man.

"Your Majesty. It is true that Qingxin Tea Workshop is the Emperor's Tea Workshop, but the point is that Qingxin Tea Workshop is the royal tea workshop appointed by the previous demon queen Wu Zetian when he was in power, when the demon queen Wu usurped the imperial power of the Tang Dynasty and ascended the throne as the emperor, it was once known as the Wu Zhou era, and the Qingxin Tea Workshop was established at that time. Perhaps, the person behind the Qingxin Tea Shop was the remnants of the Wu clan at that time, and the thief was not dead, and he was delusional about wanting to seize power again and reproduce the glory of the Wu Zhou era", the young man responded calmly, splashing dirty water on the head of the dead Wu Zetian without hesitation.

"Are you sure?What evidence do you have to prove that this is the remnants of the Wu Clan," Tang Xuanzong asked sharply, not affected by this person's seemingly sincere sophistry.

"Wechen vouched for his life, and what Wechen said was true. If what Weichen said is false, Weichen is willing to cut himself to comfort the world", Yu Chi Zhenjin quickly stood up and said at this time. Now he is already difficult to ride a tiger, stretching out his head is a knife, shrinking his head is also a knife, it is better to fight again, he only hopes that the person next to him does not scold him. With that, he didn't just glance back at the young man he had brought into the palace.

"This ......", when it comes to the struggle for imperial power, plus Yu Chi Zhenjin is a descendant of the founding heroes and a loyal general of the Tang Dynasty. Faced with Yu Chi Zhenjin's behavior of guaranteeing his life, Tang Xuanzong didn't wait to pay attention to it, he no longer paid attention to Yu Chi Zhenjin and the young man, and secretly lowered his head and thought. The surrounding atmosphere fell silent for a while, and Yu Chi Zhenjin didn't even dare to breathe.

"Jia Jingzhong", Tang Xuanzong suddenly shouted.

"The slave is here, Your Majesty", Jia Jingzhong, the eunuch of the celebrant of ceremonies, hurriedly responded.

"How many kinds of tea does the Qingxin Tea Workshop pay tribute to the royal family?" asked Tang Xuanzong.

"Your Majesty, the tea paid tribute to the royal family by the Qingxin Tea Workshop has a total of five kinds of tea: Bird's Tongue, Purple Bamboo Shoots, Yellow Buds, Mengding, and Changming, all of which are high-grade tribute teas. There will be a gift from Qingxin Tea House today", Jia Jingzhong responded.

"Immediately invite Dr. Tongtian Wang Bo from the Imperial Physician's Department to come to the palace to see me," Tang Xuanzong ordered.

"Yes, Your Majesty", Jia Jingzhong, the eunuch of the ceremonial ceremony, shouted to Gao Shen outside: "Someone is coming! Your Majesty has a decree, Dr. Wang Bo of the Xuantai Medical Department will enter the palace to see the saint." ”

"Xuan, Dr. Wang Bo of the Imperial Medical Department entered the palace to see the saint. ”

"Xuan, Dr. Wang Bo of the Imperial Medical Department entered the palace to see the saint. ”

............

"Your Majesty, the old minister and the imperial physician Wang Bo are here, I don't know what His Majesty summoned the old minister overnight?", an old man with an old medical box on his back stood in the Zichen Hall and asked Tang Xuanzong.

"It's really helpless to summon Imperial Doctor Wang in the middle of the night, and I hope that Imperial Doctor Wang will forgive me," Tang Xuanzong explained with a smile. Imperial Physician Wang Bo has served and diagnosed three generations of Tang Emperors in the Imperial Physician Department, and has the deepest qualifications and the strongest means of treating patients in the Imperial Physician Administration, no matter how domineering Tang Xuanzong is, in front of the Imperial Physician Wang Bo, he has to restrain a little, who makes the family an old doctor, and he is also a privileged Dr. Tongtian.

"I have five imperial teas here, and I heard that some people want to harm me through tea. Imperial Physician Wang's medical skills are the most skillful, and I asked Imperial Physician Wang to check whether it is poisonous or not", Tang Xuanzong said respectfully.

"Oh, how can there be such a thing? Let's take a look", the imperial physician Wang Bo took a box handed over by the eunuch Jia Jingzhong, and after opening it, there were five parts of tea leaves of different colors in it.

Imperial Physician Wang Bo opened the medical box he was carrying, took out some bottles and cans of things, and kept tinkering.

Yu Chi Zhenjin's eyes stared at the thin hands of the imperial physician, and secretly thought to himself in his heart, I hope there will be no mistakes, I hope there will be no mistakes, I hope nothing will go wrong......

"This one, there is no poisonous ......"

"This one is not poisonous......

"This one is not poisonous......

With the continuous experimentation of the imperial physician Wang Bo, one tea after another was not poisonous, Yu Chi Zhen's heart was about to jump out, and his forehead was unconsciously full of sweat.

"Young man, it is useless to be calm, to be in a hurry. Take it easy, the most important thing is to live the mentality. Look at the people, their expressions are calm, their mentality is natural, and they study hard", the imperial physician Wang Bo glanced at the nervous Yu Chi Zhenjin, and then looked at the young man with a calm expression, and said in a calm tone.

"This one, there is no poisonous ......"

"This one is not poisonous...... Wait, that's not right...... This shouldn't be like this...... I'd like to see this happen to me before...... What is it?"

Looking at the last tea leaves, the imperial physician Wang Bo fell into deep thought, slowly recalling the past.

"By the way, I remembered", the imperial physician Wang Bo seemed to think of something, and he took out a few other bottles with strange shapes from the medical box and tinkered with them.

"Yes, that's it. I knew it was like this", the imperial physician Wang Bo looked at the inspection results of the last tea and smiled with satisfaction on his face.

"I don't know, did Imperial Physician Wang find out anything?" Tang Xuanzong hurriedly asked when he saw Imperial Physician Wang Bo put down the bottle and jar in his hand.

"Your Majesty, the old minister lived up to the emperor's grace and did find out some clues. There was no poison in these five teas, but in this last tea, Lao Chen found out that it contained Gu", the imperial physician Wang Bo replied.

"Gu, what is Gu?", Tang Xuanzong asked strangely.

"Your Majesty, Gu is not poisonous. It is a kind of artificially cultivated poisonous insects, the cultivation method of Gu is very cruel, generally only with the flesh and blood of living creatures to raise it can be fed, Gu is divided into several kinds, each of which has a different cultivation method, but it is roughly the same. Gu can invisibly kill people, there is no medicine stone, and it is extremely fierce. Gu is very rare in the Central Plains, and the method of raising Gu generally originates from the countries of the Western Regions, if not, Lao Chen had some experience in the early years, and ordinary doctors may not be able to recognize it. Because it is not poisonous, the general method of testing for poison has no effect," replied the Imperial Physician Wang Bo.

"Then what kind of Gu is this?", Yu Chi Zhenjin, who was standing on the side, hurriedly asked.

"This is a dung beetle, and it is also a strange Gu among Gu. Gu eggs enter the human body with the tea soup, lurking in the blood of the person, the true qi can not be detected, and it can also strengthen people's muscles and bones at the beginning, make people energetic, and be beneficial to martial arts training. However, if you have a seizure, you will definitely die. Good Gu, this is a good Gu ......", Imperial Physician Wang Bo said seriously and frivolously.

"Dung beetle, Imperial Physician Wang, how to solve this kind of Gu?", Tang Xuanzong couldn't sit still at this time, and hurriedly asked. You know, he himself often drinks the water brewed from the tea leaves of the Qingxin Tea Workshop, what can he do?

In fact, although it was Tang Xuanzong who summoned the imperial physician Wang Bo, he still didn't believe Yu Chi Zhenjin's words in his heart. Because, after the Qingxin Tea Workshop became the imperial tea workshop of the Tang Dynasty because of its ancestral tea secret method, it has been abiding by its duties for hundreds of years, not participating in the political power struggle above the court at all, and is in a neutral identity, so after he won the throne at that time, he did not punish the Qingxin Tea Workshop, it is still the imperial tea workshop. This time, in fact, if it weren't for Yu Chi Zhenjin's fight with his life, what he said was so categorical, he called the imperial doctor Wang Bo with the mood that it would be better to give it a try. It's just that I didn't expect that the imperial physician Wang Bo really found something that shouldn't be in the tea paid tribute by this Qingxin Tea Workshop, although it is not poison, but this Gu is more ruthless than poison. However, if it is poison, it will not be able to reach the palace at all, and it should be exposed in the previous layers of strict investigation, if not, the Western Regions Gu Worm is little known in the Central Plains, how could they use the Western Regions Gu Worm to perform this kind of strategy.

In the early years, the imperial physician Wang Bo had traveled all over the world, leaving footprints in the Northern Desert, the Western Regions, Southern Xinjiang and other places, with superb medical skills and broad knowledge, if it were not for the emperor who had a life-saving grace for him, he would not have stayed in the palace to study medical skills with peace of mind. For this reason, the emperor also set up a special position for him - Dr. Tongtian of the Imperial Physician's Department, in normal times, he didn't need to do anything at all, unless he endangered the life and death of the royal family, he would take action. This time, if Tang Xuanzong hadn't suddenly thought that there was such a Dr. Tongtian in the Imperial Medical Department, maybe he wouldn't be able to find out anything, and his shallow knowledge was a hard injury.

"Your Majesty, as far as the old minister knows, dung beetles are dry and poisonous, and they must be driven away with a gentle antipyretic soup. However, Lao Chen had only heard of it, and he had not really seen this kind of Gu, and he still needed to make a few attempts, and Lao Chen was not too sure. However, if there is a person who has fallen into the Gu and asks the old minister to give it a try and think about it carefully, maybe the old minister can find a way to drive away the Gu, this is the best way", said the imperial physician Wang Bo.

"That's good", Tang Xuanzong was overjoyed when he heard that there was still a chance to be rescued, and asked Jia Jingzhong: "What kind of tea is the last tea that Imperial Doctor Wang studied?"

"Your Majesty, it's a bird's tongue tea," the celebrant Jia Jingzhong responded.

"Okay, then summon a minister who often drinks bird's tongue tea to enter the palace quickly," Tang Xuanzong ordered.

"Yes, Your Majesty. ”
