"Ping Guogong, here, is this hair enough?"

Liu Hong came to the post house and took out more than a dozen long hairs from his arms and put them in front of Tang Ping.

The hairs were wrapped around the comb that Ahsan had dropped, and he pulled them off while he was picking them up.

The two guards saw it from behind, and they wouldn't have thought that he was just going to comb the hair.

"Enough, well done." Tang Ping patted Liu Hong's shoulder: "Let's go back and rest today." ”

After Liu Hong left, Tang Ping and the three of them opened the door together, first back to Chang'an, and then back to modern times.

"San'er will go to our hospital for testing." Gou Shaoqun said: "If this is true, I am afraid that it will be difficult for you to explain it in your hospital." ”

"Okay!" The three of them took a taxi, and with Gou Shaoqun, a princeling, his family's private hospital was naturally unimpeded.

Li Shan went to the test, and Tang Ping and Gou Shaoqun took out their mobile phones and scolded each other while turning on the black.

This kind of hair test, as long as it is detected with a large fluorescence detection machine or colloidal gold detection plate, the time is still very fast.

After the two of them finished a game, Li Shan had already come out.

"How?" Tang Ping asked.

Li Shan nodded a little solemnly.

Gou Shaoqun took the test report, threw it into the shredder after reading it, and asked the laboratory to delete the test records, and the three of them left the hospital.

Back in Nanzhao, Gou Shaoqun said to Tang Ping: "Now it is very clear that the king of Nanzhao and his sons should have eaten poppies. ”

What they identified Liu Hong at the beginning was a poppy.

It is said that this thing was introduced to China during the Six Dynasties, but it has always been used as an ornamental flower.

The Tang Dynasty poet Guo Zhen wrote a poem called "Rice Capsule Flower", which is another name for the poppy.

The years of Guo Zhen's birth and death are 656 to 713, which is the earliest record of opium poppy cultivation in China.

However, from his poem, it can also be inferred that before this, there must have been records of cultivation in China.

It's just that this thing is used as an ornamental flower, so Tang Ping didn't care.

But now the symptoms of the king of Nanzhao and his son have made them suspicious.

After the laboratory test, it was also confirmed that there was indeed a poppy component in the hair of the king of Nanzhao.

And only their royal family has such symptoms, I am afraid that someone knows about the addictive nature of the poppy and has used it as a poison.

This is not allowed by Tang Ping, and everyone who is familiar with history knows the harmfulness of this kind of thing.

This is all engraved in the genes, and there is a joke on the Internet that is: if your parents know that you are drunk driving, they may choose to shield you. But if you know that you touch this thing, then you may be tied up and sent to the police station.

"Now we have to figure it out, who made this thing? How many people know about its addictive nature? Tang Ping tapped his fingers on the table next to him and said.

Li Shan asked: "Is there still no result in searching in the city with drones?" ”

Tang Ping shook his head, although drones are black technology, their scope is limited, and this Nanzhao country is really a sea of flowers.

There are blooming flowers everywhere, and it is indeed difficult to find their target in these flowers.

Gou Shaoqun suddenly looked at the two: "Are we stupid?" ”

"You are!" Tang Ping and the two said to Gou Shaoqun in unison.

"We all are!" Gou Shaoqun said: "Since the king of Nanzhao has those symptoms from time to time, it means that someone must be taking it for him regularly, and he only has that kind of symptoms when he is addicted!" ”

Tang Ping's eyes lit up: "So we just need to stare at the king of Nanzhao Kingdom, we can know!" ”

I have to say that at the beginning, several people forgot to look for this from the source.

Tang Ping no longer let the drone cast a net aimlessly in the sky to search, but aimed at the king of Nanzhao.

After observing for two days, Tang Ping and the others were a little surprised to find that no one else approached them except for the palace maid who delivered food normally.

"Did we guess wrong?" Tang Ping scratched his head, his nose twitched, and looked at the flowers on the windowsill.

"Flowers! Flower cake! Tang Ping exclaimed: "Do you remember when Liu Hong came back to report on the first day, he said that he originally planned to take away a plate of flower cakes, but was rejected by those palace maids?" ”

"That's right, he also mentioned that those palace maids said that flower cakes are eaten by His Majesty every meal, so they can't be given to him."

"So, in fact, the one used to poison is the flower cake!"

Gou Shaoqun hammered the table: "Now we should not be focusing on the king of Nanzhao, but those."

Ingredients for flower cakes! ”

The drone couldn't shoot all the way inside the imperial dining room, but it didn't bother Tang Ping.

After nightfall, Lao Cui and Lao Du quietly sneaked into the imperial dining room of the palace, and then installed two cameras in a hidden place.

Tang Ping only needs to park the drone on the roof of the imperial dining room, and the two cameras can transmit the picture to the drone.

After staring at it for another day, Tang Ping and the others finally found a suspicious character.

It's the cook who said it was Xiao Luo's apprentice.

In the morning, when all the cooks came to the imperial dining room, he put something into the flowers that made the flower cakes while everyone was not looking.

And then he is also responsible for making the filling, so he is the minion who reaches into the imperial dining room behind the scenes.

When Liu Hong went to the imperial dining room again to get the lunch for Tang Ping, he found the cook.

"I'm sorry!" Liu Hong bowed sincerely and said: "I was angry with my boss that day, so I sprinkled my anger on you, and after I went back, I thought about it was wrong for me to do this, it was in vain that I read so many books of sages." ”

The words made the cook stunned, but thinking about Liu Hong's coming over in the next few days, he really didn't make them sad.

Seeing that Liu Hong said it so sincerely, and I heard that this Lord Liu was quite generous......

As soon as he thought so, Liu Hong took out a leather square thing from his arms and handed it to him: "This is the Pingguo Gong rewarded me, it is the most popular wallet in Chang'an, which can be used to enlarge Tang coins and other money, please be sure to accept it!" ”

I couldn't help but say, so I stuffed the wallet into the cook's hand: "If you think this thing is not practical, Ping Guogong said, go to Chang'an City to have a special store for luxury goods, and you can sell it for ten yuan!" ”

"Ten times!" The cook was a little dizzy: "Can you really sell so much?" ”

His monthly income is only 300 wen a month, and ten yuan is almost what he can earn without eating or drinking for three years.

"What is the identity of Ping Guogong, do you think he will deceive people?" Liu Hong glanced at the wallet and said with some reluctance: "I really feel sorry for you, and I feel uneasy, so I gave it to you." ”

Hearing Liu Hong say this, the cook was afraid that he would take it back again, so he quickly put his wallet back in his arms and stuck it to his meat: "Okay, I accepted this gift, and you don't have to apologize anymore." ”
