At this time, a figure blocked in front of him and said to him: "Chairman, I see that we can't eat anything here, in case ...... Let me use this silver needle to see if there is any problem! Xiao He stood up and said to the Supreme Treasure.

"I don't think there's a need to be so excited, you see that these adults are so sincere in inviting us to eat this reception banquet together, and knowing that I don't drink alcohol, I also specially prepared sour plum juice, this sour plum juice looks sweet and delicious, and I use it to quench my thirst in this unbearable heat." The Supreme Treasure said nonchalantly.

"That's right, Minister Xiao. What you said really cooled the hearts of several of our old men, and it also failed the good intentions of Doctor Hua. ”

"Minister Xiao, if you really want to test poison with a silver needle, then try it! I, Hua Anxing, am standing up straight, and I won't do such a bad thing. Hua An looked like a gentleman, and even the Supreme Treasure thought that he didn't do tricks, if it wasn't for the fact that he really ate poison in the sour plum juice later, he really thought it was their villain's heart to spend the belly of a gentleman.

"Don't think I dare not try, we can't joke about the life of our chairman. The chairman told me to try it before I could drink it. Saying that, Xiao He took out a silver needle that he carried with him to test poison and inserted it into the sour plum juice and stirred it back and forth a few times, and then took it out and observed it carefully, and found that there was indeed no change on the silver needle, how could it be that there was really no problem with this sour plum juice.

Supreme Treasure felt sorry for Xiao He in his heart because he was too stupid and naïve, in fact, this silver needle poison test thing was only useful for one thing, that is, arsenic. It can often be seen in various palace fighting costume dramas that before a certain concubine eats, the eunuch is used to stirring the food with a silver needle to make sure that the food is not poisoned. In fact, the purpose of the silver needle poison test is to test whether there is arsenic, because the ancient arsenic production technology is poor, containing impurities such as sulfur and sulfide, and chemical reactions will occur when in contact with silver, but if it is modern, arsenic is refined very pure, so even if the silver needle is tested for arsenic, it will not turn black.

Someone once conducted an experiment, and three tasteless and odorless deadly poisons were selected on the spot, rat poison, thallium salt, and cyanide, and then three sterling silver needles containing 99 percent silver were put into liquid bottles containing the above three poisons; Thirty seconds later, the silver needles were removed, and none of them turned black.

Is it because the time is too short, and it is difficult for the venom to react with the silver needle? Actually, no, even if this is left for a day, they will not react, and the silver needles will not change color. Where did the ancient saying of silver needle poison test come from? Why has it been around for so many years? In fact, the poison of the silver needle test that is circulated among the people refers to a specific poison, arsenic. Another silver needle of the same purity was placed into the aqueous solution of arsenic and stirred several times; Thirty seconds later, the silver needles removed from the aqueous solution of arsenic still did not change color.

This is the arsenic refined under the modern process, the principle of silver needles turning black, silver needles encounter sulfur or sulfide will produce a kind of silver sulfide, ancient arsenic, because of backward production technology, arsenic will contain sulfur and sulfide impurities. When the sulfur contained in it comes into contact with silver, a chemical reaction occurs, causing a black layer of silver sulfide to form on the surface of the silver needle. Therefore, Xiao He wanted to rely on silver needles to test poison, as long as the other party was not stupid enough to use arsenic to poison, it would be impossible to find out what was wrong with it. And looking at Hua An's affirmative expression, he knew that this silver needle drug test was probably useless.

So the result was that Xiao He tried it in every dish and wine with a silver needle, and there was no change when he took it out, and the same was true in the sour plum juice.

"How about Minister Xiao, I said that I didn't poison at all, you also tried it with this silver needle, now you should rest assured, right?" Doctor Hua said proudly.

"I don't care, Chairman, I always feel that something is wrong, how can they become so enthusiastic about us all of a sudden, there must be something wrong with this." In fact, Xiao He is not the only one who has such thoughts, Lu Xiaoyu also found the problem. He thought that it was impossible for such a smart person as Supreme Treasure not to know that those old ministers were not sincere in their devotion to the PLA. It's just that there is no evidence yet that they want to be unfavorable to the PLA, so they have to be very cautious in everything they do.

Since the Supreme Treasure had tested the poison a few times before, his courage has become bigger and bigger, and he is not afraid of what tricks that Hua Taiyi will come up with, he wants to see what poison in this sour plum juice can make him unable to parry.

The Supreme Treasure was ready to take the sour plum juice and drink it, it is estimated that Imperial Doctor Hua felt that this scene was not similar enough, and he thought that he really poisoned the Supreme Treasure to death, and it was estimated that the People's Liberation Army would not be able to let him go. Instead of letting them be caught and ravaged to death, it is better to drink this sour plum juice now and die with the Supreme Treasure, which can also make him even more convinced that there is no problem with this sour plum juice.

So when the Supreme Treasure hadn't taken the sour plum juice yet, he first raised his cup and drank the sour plum juice inside.

"What are you doing, Doctor Hua? Didn't I believe you? I'm ready to take it and drink it, why are you just going to drink it yourself? No, you'll have to pour me another glass. Supreme Treasure was surprised that this Hua Taiyi really didn't react at all after drinking the sour plum juice, could it be that he guessed wrong? They want to kill themselves in other ways?

Doctor Hua was silent, as if angry, he silently poured another cup of sour plum juice for the Supreme Treasure, and handed it to him with both hands. Doctor Hua didn't speak during the whole process, because if the toxin that sealed the throat with blood did not come into contact with the air in large quantities, the spread of the toxin would slow down, but once he spoke and breathed, he would die in a moment, so at this time, Doctor Hua was still holding his breath!

Xiao He and Lu Xiaoyu didn't have any poisoning reaction after seeing that Imperial Doctor Hua drank the sour plum juice, but stared at the two of them deadly, feeling like saying that you saw it, I didn't lie to you, I drank it myself. Xiao He thought that Dr. Hua was angry, but he felt that some villains had the heart of a gentleman.

He was about to drink a glass of sour plum juice to apologize to Doctor Hua, when a hand stopped him, "Old Xiao, what are you doing?" Seeing that this sour plum juice is delicious, it's okay to drink it secretly? Tell you that all this sour plum juice is mine alone, and none of you can touch it, do you hear it? Let me first taste the taste of this sour plum juice. ”

The Supreme Treasure is also afraid that there are chronic toxins in this sour plum juice, if there is really a problem, let him bear it alone, and the second is that he really loves to drink this sour plum juice, he is afraid that if everyone drinks this sour plum juice, his gluttony will be hooked, and the sour plum juice will not be uncomfortable.
