And Guo Biwu's blood reacts so violently with the silver needle, and the arsenic is extracted from the essence of Heding Red - Red Letter, so it is obvious that Guo Biwu is poisoned by arsenic.

But explaining what chemistry is to people in this world must be wishful thinking. Xiao Jinse's heart turned, and then he spoke leisurely: "Your Majesty, not all poisons can be detected with silver needles, for example, poison arrow wood, broken intestine grass...... Oh, and by the way, and peacock gall ......."

While speaking, Xiao Jinse looked at Mo Ziheng and continued to explain: "These poisons cannot be detected through silver needles. ”

Mo Ziheng squinted his eyes and looked at Xiao Jinse, as if he was looking at some dangerous elements, right now this "dangerous element" was saying some poisonous names that he had never heard of, for some reason, although this girl was only seventeen or eighteen, although it was only the first time they met, he actually had a sense of convincing from his heart.

"In the whole Daluo, the poison that can be detected by the silver needle is only arsenic and Heding red, and then the toxin force of arsenic is several times that of Heding red.

After speaking, Xiao Jinse was silent. Xiao Yunzi, who was listening with soy sauce on one side, couldn't help but give Xiao Jinse a thumbs up in her heart: This Miss Xiao really has two brushes.

Mo Ziheng pondered for a moment, and didn't believe or disbelieve Xiao Jinse's words, but just looked at Xiao Jinse fixedly: "In your opinion, how should I check next?" ”

Xiao Jinse was stunned, obviously she didn't expect Mo Ziheng to ask her this.

Sorting out the cumbersome details, he looked at Mo Ziheng: "The toxin spreads so quickly, there are no more than two ways of poisoning, one is eating, and the other is blood contact. ”

Speaking of this, Xiao Jinse bowed to Mo Ziheng with a firm look in his eyes and said, "Right now, I just need to check if there are fresh wounds on the Wu nobles, the kind that sees blood." If not, then it is good to check the food that the nobles have eaten today, as long as they have touched the food and the original ingredients, they must check it. If there is a wound, then the palace maid who is close to the nobles will always have some clues. ”

After listening to Xiao Jinse's words, Mo Ziheng was like seeing the sun through the clouds, and it was extremely bright. Xiao Jinse's words are modest, in fact, as she said, when she checked it out, where did she only get some clues? I'm afraid that the cause of death of the noble people is completely understood.

Mo Ziheng's eyes flashed, and he raised his chin at the stunned man on the side.

He quickly began to check whether there were any wounds on Guo Biwu's body.

Xiao Jinse was also carefully inspecting on the side, and suddenly there was a soft sound, and the slight impact of metal and marble slabs attracted Xiao Jinse's attention.

Following the sound, Xiao Jinse lowered his head and found a delicate ring lying quietly on the marble floor, which seemed to be its voice.

Xiao Jinse squatted down and picked up the ring on the ground. The style of the ring is quite chic, silver, winding to outline the appearance of leaves, circled into a ring, which is a live buckle.

"This is what I gave to the nobleman, and she carries it every day." Seeing the ring, Mo Ziheng's heart was sour again, and his tone was slightly sluggish.

Xiao Jinse nodded, the things of the deceased should have been attributed to the deceased out of respect. Just when Xiao Jinse was holding the ring and was about to put it back on Guo Biwu, Xiao Jinse's eyes suddenly sank: "No, Your Majesty, there is something wrong with this ring!" ”
