Through the Taobao system, Li Yu quickly found out the ingredients of those pills. One of the ingredients surprised Li Su.

As Li Su guessed, the gold pill is full of precious medicinal materials, ginseng, deer antler, He Shou Wu, honeysuckle, etc., and then some heavy metals such as gold powder, silver powder, mercury, and lead and zinc.

The golden substance smeared on the gold pill is the drug opium.

The recorded history of opium production can be traced back to the Ebers Papyrus, the first drug book in Egypt 3,500 years ago.

In 139 BC, when Zhang Qian went to the Western Regions, opium reached China. During the Three Kingdoms, Hua Tuo, a famous doctor, used marijuana and opium as anesthetics; In the second year of the Tang Dynasty (667 AD), there was a record of opium imports, and the Arab opium of the Tang Dynasty was called "A Furong"; In the "Kaibao Materia Medica" published in the Northern Song Dynasty in 973 AD, opium was named poppy corn, and the latter "corn" was used as a capsule.

The painting that Qinggu Daoist showed Yuan Tiangang was a poppy flower, and the pills were extracted from its fruit.

Li Shimin took Jindan, which contained opium, and was already addicted, so he naturally couldn't do without Jindan, so he was controlled by Qinggu and others.

Li Shimin was harmed by both heavy metals and drugs, and it was normal for him to have hallucinations, and the degree of physical damage was already very serious.

Li Su loved Li Shimin deeply, so he hated Qinggu and others to the core. He was determined that he would not tolerate any mercy in this attack, and that he would completely eradicate them.

Li Su sent someone to call the director of the Overseas Intelligence Bureau, and explained to him the knowledge related to opium, and told him to try to control the source of opium for Qinggu and others.

He confessed that as long as he discovered the source of opium in Qinggu, he would immediately seize it. He wanted to cut off the supply of Qinggu and at the same time take opium into his own hands.

He had a clear grasp of the situation of foreigners in Chang'an, and soon found clues from a merchant of the Great Food Empire.

Soon after, the apprentice of Kiyoya Daoren went out to pick up the goods, and he came to the door of the merchant's courtyard, knocked on the door and entered, and never came out again.

In the afternoon of the same day, he came to the East Palace to report the situation to Li Su.

He said: "His Royal Highness the Prince, the people have taken it and seized 135 catties of opium. ”

Li Su asked, "Is there anyone else in Chang'an City who has goods in their hands?" ”

"All foreign merchants, especially in Central Asia, are monitored to ensure that the people of Qinggu will not get another opium or two," he said. ”

Li Su said: "Well done, all those who are related to Qinggu Dao people will be closely monitored. Especially those who left Chang'an, all of them were disposed of. ”

He said, "Your Highness rest assured. The minister will not have a chance to give them opium. ”

That night, the apprentice of the Qinggu Daoist still did not return, and he had a premonition that something was wrong, so he sent another apprentice to the Great Food Country merchant to check on him.

As a result, the apprentice did not come back.

Qinggu Daoist knew that something was wrong, so he hurriedly came to the Wei Wangfu and personally led the Wei Wangfu guards to the courtyard of the Great Food Merchant. As a result, the building was already empty.

Qinggu returned to the Wei Palace, found Yuan Tiangang, and the three of them discussed countermeasures together.

Qinggu Daoren said worriedly: "Things are a little wrong, today my two apprentices are missing. That's not all, the most important thing is that the source of the fairy grass is out of stock, and the inventory in the alchemy room can support it for another two or three days at most. ”

Yuan Tiangang was anxious when he heard this, and he said, "How is this good? Three days later, the emperor asked you for Jindan, what should I do? ”

Li Tai said: "Otherwise, I will show my father and the emperor that the prince sent someone to snatch it." ”

Qinggu shook his head and said, "It's useless, this is a matter without evidence, the emperor won't believe it." When the time comes, people bite back, saying that you have framed others, but you can't come up with evidence, but you are passive. ”

Li Tai was a little dumbfounded, and he said, "What can I do about this?" Now, people ignore us, and in a few days, we won't be able to do anything about ourselves. ”

Qinggu said: "Don't panic, the only way to do this is to gamble." ”

Li Tai and Yuan Tiangang asked together, "How to bet?" ”

Qinggu said: "Give the prince a problem, it's best if they can't accept it, if they don't do it, they will say that they have offended the gods, and the gods will not give them elixir." Isn't that enough?

When the time comes, the emperor will definitely be angry with the prince, and maybe the prince will be abolished. Now the emperor believes that we will definitely make King Wei the crown prince after the abolition of the crown prince. ”

Li Tai said with some unease: "In case the prince and they do it, or rather, the emperor punishes them and makes me the crown prince, you don't have the elixir in your hands, how can you explain to your father?" ”

Qinggu said: "That's not simple, after we reach the goal, I will persuade the emperor to retreat, this retreat, come to 7749 days, then you have the final say in the court, 50 days, what can you not do?" ”

Li Tai said: "Brilliant plan, great. ”

Yuan Tiangang asked, "Is there anything that His Royal Highness the Crown Prince can't accept?" ”

Li Tai smiled: "It's too simple. The prince is very hypocritical, what kind of affection does he say, he regards his wife as more important than his own life, so let him sacrifice one of his wife. I was sure he wouldn't. Ha ha. ”

Qinggu said: "Okay, that's it, Your Highness, you find someone to draw a portrait of the prince's woman, and paint it as a Taoist costume, don't paint it too realistically, just look like it." Poor Dao has his own way to make the emperor believe. ”

Yuan Tiangang said: "Clever plan, this is a dead end, I think the prince will break it?" ”

Yuan Tiangang really appreciated it, and he only now realized that when it came to being insidious and vicious, he was really far behind these two.

After the three of them discussed, Li Tai found someone to paint a portrait of the crown princess.

If you paint a portrait of an ordinary woman, it is not an easy task, people live in the back house, outsiders can't see it, and you have no reason to paint a portrait of someone's family, which is a very difficult thing.

But it's too easy to paint a portrait of the crown princess. Because the princesses basically have jobs, they often come out to show their faces, especially Li Ning'er, she has to go to work every day, and there are hundreds of people who have seen her.

As for finding a portrait, it's even simpler. Li Tai, the king of Wei, also has a very high level of painting, and he can do this, but it is inconvenient for him to do it himself, because many people have seen his paintings.

In fact, there is no need for him to take action in person, in the Wei Wangfu, those who can draw, can find ten or eight with a random stroke.

Soon, Li Ning'er's portrait was completed.
