Hearing Jiang Zhimian's words, Chi Mohan approached to see what was in her hand.

It's just that he is not very proficient in minerals, and looking at the black powder in Jiang Zhimian's hand, he doesn't know what it is.

Jiang Zhimian explained, "This black powder is nitrate that has not been processed. ”

"You've used ice cream." Chi Mohan has a good memory.

Jiang Zhimian bowed, "Nitrate is used to make firecrackers, fireworks and explosives, it is a very important ore, more precious than iron, but Mei Zhao did not report this kind of thing." ”

The reasons for this can be imagined.

Chi Mohan also recalled carefully, and on the account schedule of the warehouse, there was indeed no mention of nitrate.

"Could it be that the content is too small, so it is not reported?" Chi Mohan asked.

Jiang Zhimian shook his head, "I took a look, all the way over, there was saltpeter powder falling everywhere in the mine, and it only fell here later, people came and went, and they stepped on the powder." ”

And this situation shows that there are often people who transport saltpeter outside, and there is spillage in the process, so much powder will be left.

As for how much was shipped out, Jiang Zhimian was not sure.

The only thing that is certain is that there must be a lot of them.

"The amount of saltpeter is extremely large, Mei Zhao will definitely not hide it in the iron mine, so where is it being sent?" Jiang Zhimian began to ponder.

As he was talking, Mei Zhao's sharp voice was already heard outside.

"Little County Lord, General Mo, are you in there?"

Jiang Zhimian quickly stood up straight, patted the saltpeter in his hand clean, and smiled on his face, "Grandpa Mei, we are here." ”

It was only a cup of tea before they entered the mine, Mei Zhao came in such a hurry because he was worried that his secret would be discovered, right?

While thinking about it, Mei Zhao had already arrived in front of the two, also holding a lantern, and under the dim light, the pale cheeks looked even more terrifying.

"Little county lord, you are a daughter, how did you come to this kind of place, what kind of place do you need, just tell me, I still sent someone to the palace like last time." Mei Zhaopi smiled and said with a smile.

Jiang Zhimian waved his hand indifferently, "I grew up in the countryside, I don't have to be nervous, Grandpa Mei doesn't have to be nervous, I came here to see if there are any diamonds in here." ”

"Diamonds? What is it? Mei Zhao was stunned.

Jiang Zhimian explained, "I have also heard that there is a kind of stone in the world, which is transparent, like a crystal clear ice cube, and extremely tough, except for myself, there is nothing to cut it, it is a thing that represents the unswerving loyalty of love." ”

"Is there such a thing in the world?" Mei Zhao was very confused.

It's unheard of!

Jiang Zhimian playfully stuck out his tongue, "I also heard about it, it is said that it is in the ore, so come and try your luck, and it is not good to take advantage of the crowd, when everyone knows, what should I do if I find it and hide it?" ”

"It turned out to be for this," Mei Zhao still didn't believe it in his heart, but he began to show goodwill on his face, "I'll let those people pay attention to it tomorrow, if it is dug up, it will definitely be dedicated to the little county lord, and it will definitely not be hidden." ”

"Okay, if you dig up rubies, sapphires, yellow diamonds, etc., remember to give it to me." Jiang Zhimian said.

Although looking for gems is just an excuse, if she can really find them and make them into jewelry and the like, she still likes it.

Mei Zhao agreed one by one, and then sent Jiang Zhimian and Chi Mohan to leave the mine.

When he got out of the mine, Jiang Zhimian found that the sky was already dark, three or two stars were dotted on the dark night, and the half-moon crescent moon was dimly illuminating the path.

The horse he rode was tied to the door, and he was already impatient, foaming at the mouth of his big nostrils, and with a flick of his head, he flew everywhere.

Chi Mohan took off his robe and wrapped Jiang Zhimian in it.

A small fox, even more petite in the outer robe, only showed its small head and clear eyes.

"Grandpa Mei, then we'll go first, and we'll see you later." Jiang Zhimian said.

Gonggong Mei smiled slightly, "General Mo spoils the little county lord like this, it's really kind, then okay, I won't send it, the little county lord and General Mo should be careful on the road." ”

waited until the two of them rode away, and then their faces turned cold.

Turning around, he looked at the guard in front of him who was ventilating him, and asked, "Did they ask you anything?" ”

"Back to Father-in-law Mei's words, no, the little county lord only said that he wanted to go in and have a look, and asked for a lantern, so his subordinates hurried to inform Father-in-law Mei."

The next thing, Mei Zhao is very clear.

Mei Zhao couldn't help but bow, "I always feel that there is a problem with what kind of diamond I am looking for." ”

"That'...... Father-in-law Mei, otherwise, let's give the little county lord ......"

Before the guard finished speaking, he was stopped by Mei Zhao raising his hand.

"Don't worry, let's see if it's looking for this first, and then talk about it in case the matter is revealed."

For this matter, Mei Zhao has a 100% chance of winning.

Even if Jiang Zhimian discovers his little secret and knows that he is using saltpeter as explosives?

Will she be able to find her own place to store saltpeter?

As long as you can't find it, it's just a matter of talking.

And Jiang Zhimian's side has also returned to the palace.

As soon as he went back, Goudaner anxiously pulled Jiang Zhimian to the yard.

When he entered the house, he hurriedly closed the door and window, and then took out the little mouse from under the bed and sent it to Jiang Zhimian.

The little mice in the rat trap were jumping around alive, and there was no clue to it.

"Huh? How could this be......" Dogan was stunned for a moment, "just now it was like crazy, bouncing its feet in the cage vigorously." ”

"Springfoot?" Jiang Zhimian couldn't help frowning.

Dogdan'er nodded, "Yes, it's like a sheep's madness, and it keeps bounceing its feet, but it doesn't foam at the mouth, like this." ”

As she spoke, she lay on the bed and demonstrated it to Jiang Zhimian.

"It's not epilepsy, it's probably an acute heart attack." Jiang Zhimian said.

"Heart disease?" The dog can roughly understand what this means.

Jiang Zhimian bowed, "Yes, try again, this time give it a larger dose and see the situation." ”

Unlike humans, rats can withstand very small doses, so even when humans don't feel anything, rats can already show symptoms.

The sudden convulsions on the ground may be related to the toxins in this wine jar.

Try again, if this is still the case with the mice, then dissect the rat again and you will get the answer.

With evidence, it is easy to clean up the eldest son.

Just when Jiang Zhimian was collecting evidence of Bai Yishen's poisoning, there was also an incident on Bai Yishen's side.
