When Yun Shi was in the Dragon Yin Pavilion, he had also heard of the poison of Ice Snake Grass, but this herb was very rare in the Central Plains and was mainly unearthed in the Western Regions, so the people who could use this poison either bought it from a horse merchant from the Western Regions, or he had people from the Western Regions by his side who knew how to obtain this herb.

So this is the only clue to this matter, and then Yun Shi suddenly thought that although this matter was aimed at Concubine Xian, it was actually aimed at the queen, because Concubine Xian's only enemy in the palace was the queen, and he also searched for ice snake grass in the prince's room, indicating that the murderer finally wanted to target the queen and the prince's mother and son.

So it is very likely that the murderer is the common enemy of Concubine Xian and the queen, and the murderer will kill two birds with one stone by poisoning Concubine Xian, and then blaming the queen, and finally getting away with it.

After Yun Shi thought about this clearly, the next target to find was the common enemy of the concubine and the queen in the palace, because this person was the most motivated to commit the crime.

And this person can still enter and exit the prince's room, there are not many people who can meet the above three conditions, as long as the queen, the virtuous concubine and all the palace maids around the prince are called over for interrogation, in fact, you should be able to find the final real culprit.

Especially the palace maids around the queen and the prince, because only they have the opportunity to freely enter the East Palace, or even enter the prince's house, and put the ice snake grass into the prince's room.

So, Yun Shi took the initiative to ask to see Liu Yishan: "Your Majesty, Wei Chen already has some clues about the prince's poisoning of Concubine Xian, I hope Your Majesty will give me some time, and I will definitely be able to find out the truth." ”

"Since you are so sure, I will order you to try this case now, and you must solve it within five days. This matter implicates the crown prince, and you should have avoided it. But I believe in your ability, I will order the Xuanwu army in the palace to assist you, you must find out the truth as soon as possible, and now because of this matter, rumors are spreading in the harem, and I am not at peace. Liu Yishan said with a serious face.

"The minister's decree, the minister will not disgrace his mission, please rest assured!" After finishing speaking, Yun Shi walked out of the temple.

Then, Yun Shi immediately ordered the Xuanwu Army to summon the palace maids around the queen and the prince to the East Palace, and then began to inquire one by one, and then wanted to get some clues from them.

But in the end, nothing was found, because among them, the only maids who could get close to the prince's room were Qiuyue, Mengli, and the two, of which Qiuyue and Mengli were the henchmen of the queen, and it was impossible to frame the queen and the prince.

And Fang Ruo, who was next to the prince, had just arrived at the prince's side, and the prince brought it back from outside the palace, and the prince had a life-saving grace for her, so she had no motive to frame the prince.

However, Yun Shi started on the other hand, so they didn't have any motives on the surface, but they could check their origins and backgrounds to see if their families would have any grievances with the queen.

Sure enough, Yun Shi found out some clues from it, this prince rescued Fang Ruo from outside the palace, because it was saved by the prince, so the Inner Mansion Division did not have detailed information about Fang Ruo's family background, but it was recorded as a fatherless and motherless, and he was an orphan.

But after the verification of the Xuanwu Army, this palace maid Fangruo has a mother outside, and her mother actually has something to do with Liu Mufeng of Wenxuan.com.

Liu Mufeng's biological mother was a palace maid in the palace at that time, and Fang Ruo's mother was the palace maid's sister, so Fang Ruo's behavior was very suspicious.

First of all, she pretended to be an orphan girl, which attracted the prince Liu Xifeng to rescue her into the palace, and then she was the palace maid next to the prince, and her mother was also related to Liu Mufeng, so she was the most suspicious at this time.

So Yun Shi ordered the Xuanwu Army to bring his mother into the palace, and now pressed her into the palace dungeon, and then Yun Shi took the Xuanwu Army to personally arrest Fang Ruo, and then let the two meet briefly in the prison.

Then Yun Shi began to interrogate the palace maid Fang Ruo, in fact, Yun Shi only knew that their mother and daughter had a relationship with Liu Mufeng, and they deliberately approached the prince, so they must have a plan.

However, he did not know the purpose of their mother and son approaching the prince, so he captured Fang Ruo's mother in the palace and let Fang Ruo see her mother in the dungeon.

Then when Yun Shi interrogated Fang Ruo, he deliberately said: "Fang Ruo arrested you at this time, in fact, because we have found out the real culprit this time, it is your mother, and your mother has confessed, but she only has one request to let you go, because she said that she forced you to do all this, and everything has nothing to do with you." ”

When Fang Ruo heard this, his heart was immediately confused, and then he cried and said: "No, all this has nothing to do with my mother, I made my own opinion, I want to poison the virtuous concubine, and I also want to frame the Son of Heaven, please cure my crime and let my mother go!" ”

"Oh? Then why did you poison Concubine Xian, why did you frame the prince? Yun Shi asked suspiciously.

Fang Ruo then said everything, "My mother's sister, who is also my aunt, was originally a maidservant in the palace, but once she received the favor of His Majesty today, and finally became pregnant with a dragonborn, and finally gave birth to a prince, which is now King Wenxuan. And after my aunt gave birth to Queen Wenxuan, she died suddenly. The diagnosis of the imperial doctor was that she died in childbirth, but in fact, my mother knew that my aunt was actually killed by the queen.

The queen originally wanted her mother and son to die twice, but in the end, her aunt successfully gave birth to the prince, and the aunt was finally killed by her. The aunt's child was adopted by the current concubine, all thanks to the queen. The queen is most nervous about his son now, so I deliberately approached the crown prince so that one day, I can bring down the queen. Fang Ruo said viciously.

"Since you hate the queen so much, why do you want to poison Concubine Xian?" , Yun Shi then asked.

"Because that Concubine Xian is not a good thing, she snatched my aunt's child, and when I arrived in the palace, I learned that Concubine Xian and the queen were not in harmony, so only by poisoning Concubine Xian could I successfully marry the queen. So you see, I did all of this, and it had nothing to do with my mother. Fang Ruo shouted at Yunshi.

Yun Shi sighed, "Thank you for telling me the truth, in fact, your mother didn't say anything to me, but I will promise you to put your mother back, and then take good care of your mother." ”

Fang Ruo realized that she had been deceived, and then shouted at Yun Shi, "You liar, you help unscrupulous people like the queen and the crown prince, and you won't end well in the end!" ”

Yun Shi had no choice but to walk out of the dungeon, and then found Liu Yishan to recover his life, although the case was clear, but he was not happy at all......
