On the other side, the four princesses were about to rest after freshening up, when they suddenly heard a "squeak" on the door, and Ruan Wanwan, dressed in a black cloak, appeared at the door, startling the four princesses.

"Late? It turned out to be you, this late midnight, why are you dressed like this? ”

Ruan Wanwan untied the tie around her neck, took off her cloak, and gently placed the flower pot in her hand on the table.

The fourth princess was even more surprised: "I also hugged such a pot of weird flowers." ”

Ruan Wanwan said: "You also think it's weird, right?" ”

The fourth princess heard the deep meaning in her words, and carefully studied the basin for a while, but she didn't see anything unusual.

"It's not weird, it's just that the color is brighter, and the others are nothing special, where did this flower come from?"

"I just quietly entered the palace and saw the queen's mother, and this flower was taken out of her palace."

The fourth princess was taken aback again: "Didn't the emperor say that no one is allowed to visit the queen without his permission, how did you get in?"

Ruan Wanwan briefly told her the ins and outs, and said: "I always feel that there is something wrong with this pot of flowers, and I can't find where the problem is for a while, or you can help me take a look."

The fourth princess finally understood what was going on and asked, "Are you suspicious, someone wants to poison the queen?"

Ruan Wanwan carefully inspected the flower pot, nodded and said, "It's very possible."

The fourth princess also stepped forward and was about to take a closer look, when suddenly a strange smell came into her nose.

"This flower...... Why do you smell some herbs? ”

The words of the fourth princess reminded Ruan Wanwan, and she suddenly thought that the fourth princess had studied medicine and understood some pharmacology.

"In your opinion, where did the smell of these herbs come from?"

The fourth princess looked through the branches and leaves, and dug a little dirt in her nails, and the more she examined it like this, the more surprised she became.

"It seems that there are really people who want to take this opportunity to be unfavorable to the queen."

Ruan Wanwan's face also became grim, and said, "This flower, let's put it in your room tonight, you can help me check it and see what is strange in it."

Needless to say, the four princesses also had this intention. I said yes right away.

Ruan Wanwan fell asleep restlessly, hoping that there was something wrong with the potted flower, and hoping that it was okay, so she didn't sleep well for a night.

By dawn, I was finally a little sleepy, but there was a knock on the door outside.

She had no choice but to get up and open the door with two huge black circles under her eyes, and the fourth princess stood outside, her expression was very serious, holding the pot of red and bright flowers in her hands.

"The results of the inspection are in."

Ruan Wanwan suddenly fell asleep, pulled the fourth princess into the room, and closed the doors and windows.

"I checked last night and there was something wrong with the potted flowers."

As she spoke, the fourth princess took out a paper bag from her sleeve, which contained some unknown medicinal herbs and some dirt on it, which seemed to have been dug out of a flower pot last night.

"This thing is called sea buckthorn grass, it comes from the Western Regions, if it is combined with other medicinal materials, it is life-saving and curative, but if it appears alone, it is a deadly poison."

Ruan Wanwan looked at the pile of medicinal herbs carefully, wanting to touch it, but she was afraid of its toxicity.

The fourth princess saw her scruples: "Direct contact with the skin is no problem, its toxicity is mainly transmitted by smell."

He continued: "There is nothing wrong with that pot of flowers, but someone put some crushed sea buckthorn grass in the soil where the flowers are planted, and after the palace maids have watered the flowers, the sea buckthorn grass in the soil will absorb water and exude a burst of fragrance, which is mixed with the fragrance of the flowers, and it is not easy to be detected."

"They want the queen to smell this poison every day and kill her slowly."

There was no need for her to continue, Ruan Wanwan already understood what was going on.

The fourth princess was a little frightened, she had been in contact with medicinal materials for so many years, and it was the first time she had encountered this kind of living case of killing people with medicinal materials.

"Yes, there are not many sea buckthorn plants in the pots to raise suspicion. At first, people who have smelled the smell will have problems such as mental fatigue and drowsiness, and as time goes by, they will slowly become weaker and weaker, and they will become stupid, delirious, and even crazy. By the time he found out, he was already terminally ill and unable to return to heaven, even if Hua Tuo was alive, he couldn't be saved. ”

The more Ruan Wanwan listened, the more angry she became, and she clenched her fists tightly: "They are too ruthless to come up with such a vicious way to deal with the queen."

The fourth princess sighed: "Yes, the queen is now older, and her health is not as good as before, if we don't find the clues in the flower pot today, when the queen has an accident, everyone will only think that it is her own problem." And there is no suspicion of anything else. ”

Ruan Wanwan thought of a question: "Is there no antidote to this sea buckthorn grass?"

The fourth princess said: "If the poisoning is not deep, it can be slowly adjusted, and if it is too late, it will be completely hopeless."

She held Ruan Wanwan's hand and said with some fear: "Fortunately, you kept an eye on it last night and moved the flower pot back, otherwise, we are afraid that we will be kept in the dark."

The queen was murdered, this is a big deal, the fourth princess has never encountered such a thing, and she has long run out of ideas.

"Wanwan, what are you going to do, should we report this matter to the emperor?"

Although Ruan Wanwan was also very scared and worried, after all, her psychological quality was better than that of the fourth princess, and she had not yet reached the point where the six gods had no master.

She thought for a while and shook her head at the fourth princess: "You must tell the emperor, but not now."

"But...... It can't be delayed any longer, if there is often this thing in the queen's room, the body will be greatly damaged. ”

Ruan Wanwan lowered her head, thought seriously for a while, and said, "Don't tell the emperor for the time being, but...... We can give the queen a wake-up call and ask her to be careful. ”

The fourth princess was at a loss, and now seeing Ruan Wanwan so calm, she seemed to have found the backbone, and she was not as anxious as she was just now.

"What are you going to do?"

Ruan Wanwan patted her hand and comforted her: "Don't worry, you must keep this matter secret, and you can't let a third person know, before we get the evidence, we must not startle the snake."

The fourth princess nodded vigorously, and promised again and again: "Okay."

Ruan Wanwan glanced out the window, the sky was already bright, and it must be very inconvenient to enter the palace to see the queen at this time, so she could only wait for another day and go out when it was dark.

However, Ruan Wanwan didn't want to wait so long, the sooner this matter was resolved, the better, and something could happen later.

She comforted the fourth princess, and after sending her out, she called her personal maid in.
