Wei Qingqing smiled and answered, "What the county lord said is that I have many ways, and I will not disappoint you!" ”

The smug smile on the face of the county lord of Wuyang was blocked by Wei Qingqing's words, and he instantly froze, as if he didn't expect that Wei Qingqing could be so arrogant without the shoe prints.

The eldest princess of Jinyang turned slightly pale, and asked Wei Qingqing: "Do you still have a way?" ”

"The eldest princess doesn't have to be angry, the courtiers have already prepared, and the shoe prints are intact!" Wei Qingqing said that he ordered Bai Qi to untie the small burden and expose the wrapped objects to everyone, "I thought of a way to expand the shoe print!" ”

When everyone heard this, they were immediately very curious, and their eyes fell on the white object, and Mrs. Yu stepped forward to take a closer look at the object......

It was a long brick board that looked like it was made of white clay, and the raised part of the board was a complete and clear shoe print, and the lines on the shoe print were so clear that it looked almost exactly like the real sole.

Mrs. Yu reached out and touched the white brick board, "Is this really the shoe print on the muddy ground before?" ”

Wei Qingqing nodded, "Exactly, the two sisters who guarded the shoe prints were also present when I extended the shoe prints, and they watched me rub the shoe prints little by little, if the lady doesn't believe it, you can ask them!" ”

When the two palace maids heard this, they stepped forward together and told what they had seen yesterday to confirm that what Wei Qingqing said was true.

Mrs. Yu's gaze at the shoe prints suddenly became rare, and she couldn't put it down and stroked the patterns on it, "What did you use to extend the shoe prints?" ”

"I'm good at medicine, so I'm naturally most familiar with the matter of curing diseases and prescribing medicines," Wei Qingqing began to fool everyone, "so I use the most common medicinal herb - gypsum." ”

Wei Qingqing suddenly ordered Bai Qi to go to find all kinds of medicinal materials yesterday, the purpose was to find the flavor of gypsum, and other medicinal materials such as wolfberry, angelica, and astragalus were just used to hide people's eyes and ears.

"Gypsum raw use has the effect of clearing heat and quenching fire, removing annoyance and quenching thirst; Calcination has the effect of gathering sores and muscles, collecting dampness and stopping bleeding. These are the two most common uses of plaster, and most doctors understand them. ”

"But few people know that gypsum can be used for another purpose—gypsum slurry can be obtained by mixing gypsum powder with water, and gypsum will be extremely cohesive and can be used to make gypsum objects with accurate shapes."

Wei Qingqing was afraid that everyone would not understand, so he gave a simple example, "You can use shoe prints with only shallow traces as a mold for making pastries, and gypsum paste as dough put into the mold." ”

"What a pastry mold can engrave on the dough, what a shoe print can engrave on the solidified plasterboard. There are two differences between the two: one is that the gypsum slurry is thick and cement-like when poured, and the dough is a lump; ”

"The second is that after things are formed, the pastry is soft and fragile, while the gypsum board is a hard and unbreakable object."

"Wonderful! What a wonderful analogy! Simple and popular, one click! Before Wei Qingqing's words fell, Mrs. Yu high-fived and praised.

The eldest princess of Jinyang and the others also quickly understood, knowing that Wei Qingqing was using the method of making pastries to engrave the shoe prints in the mud on the gypsum board.

"How did you know that you could use gypsum to make shoe prints?" When Mrs. Yu encounters something she is interested in, she likes to break the casserole and ask the end, so the questions are thrown out one after another.

Wei Qingqing lied and fooled her without changing her face, "I saw this method on an ancient book, but unfortunately that ancient book was burned to ashes in a fire." ”

She cleverly made up an excuse to gag Mrs. Yu's mouth, lest she propose to borrow an ancient book to read it.

Mrs. Yu was really disappointed when she heard this, "It's a pity that that kind of worldly treasure has been burned to ashes!" ”

"Since the shoe prints are still there, why don't you quickly find out the poisoner?" The county lord of Wuyang urged angrily, she was really angry in her heart - this Wei Qingqing actually relied on some gypsum dough to make another comeback!

"Don't be impatient," Wei Qingqing was not in a hurry to reveal the answer, but only spoke unhurriedly, "Let's restore everything from beginning to end first, so that we can straighten out our thoughts and find the person who poisoned us." ”

"First of all, the county lord of Wuyang wanted to make a fool of me today, so Tete prepared a medicinal powder for me, and instructed the maid Zijuan to sneak into the teahouse and put the medicinal powder into my teacup...... This matter is what the county lord of Wuyang said himself, right? Wei Qingqing paused as she spoke, deliberately looking at the county lord of Wuyang and waiting for her to admit it.

The county lord of Wuyang snorted coldly and reluctantly admitted: "No mistake. ”

Wei Qingqing then continued: "Everyone may ask, there are so many teas in the tea room, who knows which tea will be delivered to me after it is served?" This is actually very simple, and I think Mrs. Yu can answer it. ”

Mrs. Yu gave Wei Qingqing a lot of face, and did not hesitate to cheer her up, "I have gone to the flower hall before and found two key places: first, only Princess Huaisi drank milk at the banquet; ”

"The second is that the banquet is not a round table but a long table, each table can just accommodate two people, and Princess Huaisi, who drinks milk, happens to sit at the same table with Mrs. Wei."

Mrs. Yu told everyone that the tea cups in the tea room were all two on a tray, and one tray was brought in by a maid, just for a table.

That is to say, the tray with a cup of milk and a cup of tea will definitely be sent to Princess Wise's table by the maid.

Therefore, if you want to poison Wei Qingqing, you only need to put medicine in the tea next to the milk.

"Mrs. Yu is really as careful as dust." Wei Qingqing first praised Mrs. Yu, and then asked: "Lord Wuyang, what Mrs. Yu said is correct, right?" That's how your maid Zijuan poisoned me, right? ”

"No mistake." The face of the county lord of Wuyang was a little ugly, and she gritted her teeth with hatred for Wei Qingqing forcing her to admit her mistakes over and over again, and she couldn't help but answer!

"There is an old saying that 'the praying mantis catches the cicada and the yellow finch is behind', and the purple cuckoo doesn't know that he has been targeted for a long time! The man followed Zijuan all the time, and when Zijuan had finished poisoning, she went on to put the poison into my teacup! ”

"After the man finished poisoning, he found an opportunity to get close to Zijuan, and thought of stealing the bag on Zijuan's body, and after he succeeded, he replaced the spices in it with poison, and then sneaked back to the teahouse and threw the bag in a hidden place, leaving a perfect backup for himself to borrow a knife to kill people!"

"It can be seen that the poisoned person is quite scheming, although I was given a poison that would not attack immediately, but I still cautiously thought about the way out in case of an incident, so that this matter could not involve her in any case, it can be said that one step is three steps."

The eldest princess of Jinyang heard this puzzled opening and asked, "You also said that the tea cup next to the milk will definitely be delivered to you, so why was Concubine Li poisoned in the end?" ”
