In order to prove their innocence, these disciples naturally did so.

After all the male disciples gathered around, Yi Fang explained in detail the new traces found outside Mo Hao's window.

During this period, Luo Shiyao and several other disciples of the Colorful Sect had been carefully observing the movements of these male disciples, especially when Yi Fang said that he was going to check the shoes of everyone present, he quietly kept an eye on everyone's feet.

It's just that the thief seems to have some determination, and so far there is no abnormality.

At this time, Jin Chan, a handsome and old-fashioned disciple of the Imperial Gold Sect, questioned: "Even if the person who was poisoned doesn't have time to go back and change his shoes, I don't know how many steps back and forth, and the traces on the soles of the shoes have already been rubbed clean, if Senior Sister Yifang wants to find through the soles, I'm afraid it will be difficult to achieve." ”

Everyone's eyes focused on Yifang again, and some even looked disdainful, feeling that her method was a little taken for granted.

Yifang looked like she was in her chest, and replied, "I have my own way." ”

During this period, Chi Li never asked to interrupt Yi Fang, if it was just Yi Fang who said these words, she would naturally have a lot of doubts. But after guessing that it was Luo Shiyao's instructions, he felt that things were basically in order.

Whether he likes this stinky boy or not, but after more than ten years of getting along, he has to admit that Luo Shiyao is a little different, and he has many whimsical ideas when encountering problems, and he can often get twice the result with half the effort.

"I have studied pharmacopoeia since I was a child, and I have personally tested ......" Yifang is not good at lying, so these two sentences are not very natural, but fortunately, everyone's attention is on the facts of the case and does not think much about it.

“…… It was discovered that all drugs in the world are divided into acid-base amphoterides, and a reagent was made to detect acid-base properties.

This reagent will turn grass green when it encounters acidic drugs, giving off a very special fragrance; When encountering alkaline drugs, it will turn red, the deeper the alkalinity, the stronger the red, and even emit a pungent smell when it touches alkaline substances.

And this Netherworld Sun Grass Ash is the most alkaline thing, so the residue of the sole may be able to escape the naked eye, but it can't escape my acid-alkali reagent. ”

As she spoke, she took out the white porcelain vase that Luo Shiyao had given her.

"All you have to do is take off your shoes and try it."

The corners of Luo Shiyao's mouth curled almost imperceptibly, because one foot finally shook unconsciously, as if he wanted to wipe the soles of his shoes with his hands, but immediately stopped.

Although the trembling was very secretive, it was still captured by Luo Shiyao, who had been paying attention.

Luo Shiyao naturally couldn't really create a pH reagent, he didn't even know the acid-base properties of the Netherworld Sun Grass, so he just learned and used it to make the lie seem more real.

The actions made by people subconsciously are often difficult to control, and when the thief heard that there was incriminating evidence on his shoes, he would subconsciously want to take a look, so Luo Shiyao kept an eye on their feet.

Of course, these people are not ordinary people, and it is still very possible to hold back.

So Luo Shiyao still has a backhand.

Being a thief is a well-known truth, but not everyone can make perfect use of this psychology.

In this matter, the key to exposing the weak-hearted thief is that he must believe that the acid and alkali reagent in Yifang's mouth will definitely be able to detect the drug residue on the soles of his feet.

As long as he believes it, he will definitely find a way to evade inspection.

No one will show the bloody butcher's knife to the scout, and even if he is suspected, he will do everything possible to hide it and put it in death.

It's better to be suspected than to be hammered.

So, how do you make people believe in this theory of acidity and alkalinity?

It is definitely not enough to just say it, he has just made arrangements.

If everyone's feet don't move, someone will question Yifang's acid and alkali reagent, and she will use the incense ash and reagent in her hand to prove it to everyone, so that they know that after the incense ash in her hand is mixed with the reagent, it will really turn red, and it will emit a pungent and choking smell.

Luo Shiyao's storage bag brought a lot of condiments, all of which he had tasted for more than ten years, and because there were too many types, each bottle was made into a yin and yang bottle by him.

And half of the bottle he had just given Yifang was filled with cumin, and the other half was chili.

So it's really possible to "try" it.

As long as the thief believes in the reagent, then he will definitely do everything possible to avoid inspection, and he will naturally reveal flaws.

Although this method is not 100% successful, it is definitely a method worth trying, with a high success rate and the fastest method.

Even if he really failed, he still had the clue of Netherworld Sun Grass, which was not a spirit plant that anyone could have.

Starting from the poisonous incense, the time of the crime, and the interpersonal relationship between Mo Hao and Mo Cheng, it is nothing more than spending a little more time, and you will definitely be able to find out.

But fortunately, the thief is still too young and has already been exposed, so he can directly detect and frame him and force him to admit it.

Well, he did it in the first place, and it can't be regarded as a false accusation.

None of the people present had obviously heard the discussion on the acidity and alkalinity of drugs, many people had doubts flashing in their eyes, some people had some disdain on the corners of their mouths, and some people thought that Yifang was bluffing and luring thieves to reveal their flaws.

Looking forward to what comes next, I wonder if any idiot will refuse to check.

But no one took the initiative to question it.

Because everyone knows that whoever is questioning Yifang's investigation now and acting too active will be suspected by everyone.

So the scene seemed quiet for a while.

Luo Shiyao had already told Yifang the person who was shaking his feet behind Yifang, she snorted coldly and glanced around, and said directly: "You guys take off your shoes." ”

The shaky man couldn't stand anymore and began to rub his feet back and forth gently.

Luo Shiyao said in his heart that you kid is so easy to deceive, and he is really an iron man.

Just as many disciples bent down and were about to take off their shoes, Chi Li Xianjun frowned slightly, stepped forward and said in a deep voice: "This apprentice of mine has been very smart since he was a child, and he likes to drill camps, this method of testing the acidity and alkalinity of drugs has been seen before in this palace, so ......" Sister Ba's eyes suddenly became a little sharper, swept over the people present, and her cold voice was a little threatening: "This palace advises you to stand up by yourself, so that you can suffer less flesh and skin." ”

As the person who knew Luo Shiyao best, others might not believe this acid-base theory, but Chi Li knew that this child had grown up, and all kinds of strange knowledge in his head was like an inexhaustible treasure.

So she was convinced of the acid-base theory.

The reason why the thief stood up by himself and suffered less from flesh and skin was not how kind she was, but simply because she felt that it was indecent for so many people to take off their shoes together, and she didn't want to smell their stinky feet.

Everyone present immediately stopped taking off their shoes and began to discuss, and some of the bolder ones began to shout.

"Chili Immortal Jun has spoken, who did it, hurry up and stand up yourself."

"Now I can stand up and suffer less flesh and skin."

"That's it, Chili Immortal Jun has said it, then this reagent will definitely be able to find you, and if you are smart, you shouldn't resist stubbornly."

……

Sister Ba is very prestigious in the Dao Sect, if it weren't for Yu Zisu's birth, almost everyone thought that after the death of the White Feather Immortal, she would take over the position of the head of the Colorful Linglong Sect.

With her endorsement of the acid-base theory, no one finally questioned it anymore and believed Yifang's words.

This naturally includes Li Changfeng, although he is messing around, he still has knowledge.

So he gritted his teeth, slightly stiffened his neck, and strode out with an expression of nonchalance.

"I ordered the incense." …… Do you dare to kill me?
