"By the way, the glass I wanted that day?"

"I've ordered someone to rush to make it, so I guess it can be delivered in two days."

"Okay, thank you Steward Yan."

Yan Hewen didn't say anything, just bowed down and saluted him to leave.

Ning Qi immediately brought this box of saltpeter into the house, the color of saltpeter brought by Yan Hewen is very pure white, the main ingredient in this natural saltpeter is potassium nitrate, followed by sodium chloride and □□.

However, these two substances are relatively stable under heating and are not easy to decompose, so potassium nitrate can be directly replaced by natural saltpeter to make oxygen.

This experiment is actually quite simple, just heat it, the question is what to use for oxygen? It was really a headache, and after thinking about it for a while, Ning Qi decided to try it with a bottle first, and if it could really produce oxygen, he would find something to fill it.

On this day, Ning was so busy that he didn't even eat lunch with Yan Yunzhou, and at noon, Yan Yunzhou looked at the empty chair opposite and asked:

"What about Ning Gongzi?"

"Lord Wang, Ning Gongzi is in the room in the morning, and I don't know what I'm doing."

Yan Yunzhou thought about Yan Hewen's words yesterday, his face was a little unsightly, and he waved his hand, the man retreated, and the one in the palace had been inquiring about the news of the firearms battalion under him in the past few years.

This firearm was originally developed by the first emperor, and it was first used in the northern army, but the power of firearms at that time was not great, and it can only be said that it was better than nothing, until later, Tianling Zhenren of Yuqingguan improved the ratio of the original firearms on that basis, and the power was greatly improved.

The battle with Beimu three years ago was extremely dangerous, and he was forced to use firearms on the battlefield, and it was after that that that the fear of him in the palace became even deeper.

If he was really a Ming Jun, he wouldn't hide this thing, but now, he had to think about it more.

If he dies in the coming day, the soldiers who fought with him in the north may not have a good end, and if he repeats the mistakes of the south, then Daliang will face the iron hooves of Beimu.

He put down his chopsticks and was in no mood to eat, Yan Hewen stepped forward:

"Lord, I want to go over and have a look."

Yan Yunzhou's chest was so tight that he coughed twice, and just as he was about to speak, a small head poked out at the door:

"Second uncle?"

At the door is a little girl wearing a baby pink jacket, who looks cute and looks like she is six or seven years old, it is the widow of Yan Yunzhou's brother, Yan Yueqi:

"Come, come."

Seeing that the little girl Yan Yunzhou's face was much gentler, she beckoned to her, and the little girl ran in, obviously very close to him, and directly handed Yan Yunzhou a piece of pastry:

"What's wrong with Ji'er? Didn't learn the rules with Mama today? ”

Yan Yunzhou took the pastry in her hand and carried the little girl to the chair next to her, but the little guy hooked his neck slimy:

"Second uncle, why hasn't the third uncle come to see me for a long time?"

The little girl's unintentional words made Yan Yunzhou's heart ache, but she didn't show it in the slightest:

"Your third uncle went to a far away place, and he was in a hurry, so he didn't say goodbye to Ji'er."

The little girl just asked casually, and was soon taken by Yan Yunzhou to forget the topic just now, and just hooked his neck to be coquettish:

"Second uncle, did you give my brother a pony? I want it too. ”

She didn't take a nap after dinner today but sneaked over to ask for a horse, Yan Yunzhou smiled, the eldest brother's eldest son is 9 years old this year, and he just sent a small foal a few days ago, ready for him to use it to practice riding and archery, which is the little girl is also greedy.

"Well, let's do it, the second uncle gave you a foal, but you can't ride it now, you have to wait until you are older, if you want to run a horse, you can only let your female teacher take you there."

The Flame King's Mansion is a military general, although he is not too harsh on children, but what should be learned is always to be learned, that is, Yan Yueqi is less than seven years old, and there are female teachers around him.

Let the little girl Yan Yunzhou send away the little girl, his face also showed tiredness, and he was interrupted by his niece, Yan Yunzhou also stopped thinking about going to see Ning Ji now, he stood up and commanded Yan Hewen:

"Rather you go and stare there, if so, if he is really from the palace, control it first."

"Yes."

Ning Qi was stuffy in the room at the moment, made a simple shelf, used to fix a glass cup, filled the glass cup with saltpeter, and heated it with an alcohol lamp.

But now there is no alcohol, he originally wanted to use candles instead, but obviously the little heat of the candle is not enough to stuff his teeth, so in the end he can only ask Shun Cai to go to the kitchen to ask for some firewood and charcoal, and put it under the bottom to heat.

Momotsuki and Shuncai didn't know what he was doing, but they could only do as he was told, and without a glass tube, Ning Yi used a thin bamboo tube hollowed out to draw out oxygen.

But the reaction effect is not significant, after heating for a long time, the reaction is very slow, Ning Qi sat on the side and sighed, it seems that there is no manganese dioxide catalysis or not.

He vigorously recalled what he learned when he was in school, manganese dioxide is different from potassium permanganate and is easy to decompose, and natural manganese dioxide exists, mainly in soft manganese ore.

He called Shun Cai and described the appearance of pyrolite, he remembered that it could be in the mountains, on the rocks, it was not a deep mine, and now it had come to this point, and he would make everything about this oxygen.

"Young master, do you mean that gray and black clods? Clusters and clusters? ”

Ning's eyes lit up:

"yes, you've seen that?"

"Well, I should have seen it, that thing is a little soft, and it can write on the ground."

Ning Yi immediately grabbed him:

"Where have you seen it? Get me right now, and get me all the types of things you've ever seen. ”

Ning Ji said to the housekeeper and only said that Shuncai would help him buy some things, and Yan Hewen did not stop him.

He understood what the prince meant, as long as Ning Zhi was not really angry with the palace, he would not care, and only hoped that the Ning Gongzi in front of him would not disappoint the prince.

Shuncai went out through the side gate, and the horses of the palace could not be used, so he hired horses out of the city with the money given by Ning Yao, and came to the vicinity of Zhuangzi, where they used to live.

He remembered that there was something behind the mountain, and he was very careful all the way as Ning Ji told him, but Ning Ji obviously didn't know what was going on outside.

Yan Yunzhou was assassinated, Dali Temple was arrested all over the city, but this palace is like an iron bucket that can't be entered, and now I don't know how many people are staring at this palace.

Shuncai is wearing the slightest inconspicuousness, other people may not care, but the people of the Hou Mansion of Anyuan recognize him, Ning Wenhong has been crazy for the past two days, and the people of the Hou Mansion have followed him immediately when they saw Shun Cai come out, but they don't want all this to be seen by the secret guards of the palace who are secretly staring at the back.

Shun came back after dark, and brought back a bag of ore, Ning Ji didn't even eat dinner, and when he saw what he brought back, he had to verify it the same.

But he didn't want him to do it just now, the door in the house was suddenly pushed open from the outside, Yan Hewen stood at the door with people, and the guards on both sides were carrying swords, which didn't look like they were bringing him dinner, and Ning Yi was also stunned.

"Steward Yan?"

"Ning Gongzi, I'm afraid it's inconvenient for you to live here, let's talk in another place."

Ning Jiao's heart jumped, what is the situation? Where to speak?

"Offended."

Yan Hewen raised his hand slightly, and the guards behind him immediately stepped forward to suppress Ning Yao, who didn't have time to resist, and only spoke in a hurry:

"What does this mean? What about your lord? Let go. ”

Ning Qi was covered by someone before he finished speaking, his eyes were covered with black cloth, and when he opened his eyes again, he had already arrived in a place where it was dark and cold all around, and only the candles lit on the walls could illuminate this place.

A dark, damp smell came to his face, and he remembered that he had just descended the stairs, so this should be underground?

Ning Zhen really didn't understand what was going on? He stared at Yan Hewen who came over:

"Where is this? What about your lord? Let me go. ”

Yan Hewen looked at him expressionlessly:

"Ning Gongzi still wants to see the prince at this moment?"

As soon as these words came out, Ning Qi's heart was full of thoughts, why couldn't he see Yan Yunzhou? Suddenly, a terrible thought came to him, was Yan Hewen a spy buried next to Yan Yunzhou? He was arrested, has Yan Yunzhou already been poisoned?

"What happened to the prince?"

Ning Ji began to look around as he spoke, could it be that Yan Yunzhou was also arrested?

Yan Hewen frowned slightly when he heard his words, but he was used to acting, no wonder the prince treated him differently, but unfortunately, he was sorry for the prince's blue eyes.

"Ning Gongzi has no need to pretend at this time, your attendant went out of the mansion to see someone and brought something back, don't you know?"

Ning Yi raised his head suddenly, his pupils shrank, so it was Yan Yunzhou who caught him?

Shuncai was immediately brought up, and he looked at Ning Jiao's gaze in horror:

"Childe, I really don't know anything, I just ran into the head of the original Zhuangzi..."

Yan Hewen snorted coldly:

"Just the head of the village? Isn't the head of the village the steward of your Houfu? The little father-in-law next to the steward, do you think the secret guards of the palace will not be recognized? ”

Shuncai's eyes were full of horror, his words were silent, and Ning's heart was cold, father-in-law? The people in the palace? He hasn't been here for a few days, Momotsuki and Shuncai have been by his side, although he doesn't fully trust them, but there are only these two people around who can still be used.

He didn't think about it so much today, the people in the palace were-for-tat with Yan Yunzhou, so he decided that he was from the palace.

"Childe, I really didn't say anything."

"Take it down, and when asked, he said why."

Ning Ji watched Shuncai being pulled down and immediately spoke:

"Wait, what did he know when he first came to the palace? I want to see Yan Yunzhou. ”

"Ning Gongzi is really hard-boned, someone is coming..."

Before Yan Hewen finished speaking, the door was opened by the guards, and the attendants on both sides bowed:

"Lord Wang."

Yan Yunzhou fell to the ground with a thick cloak, his face was white and terrifying, he coughed sideways for a long time before he raised his head to look at Ning Qi, his eyebrows and eyes were cold:

"Ning Gongzi is actually a person in the palace, but this king is disrespectful."

The author has something to say:

It's over, I'd rather be in danger

Chapter 16: This King Gives You Another Chance

Yan Yunzhou's words almost directly sentenced Ning Jiao to death, and Ning Jiao's palms began to sweat, this era is not the era of the rule of law that he used to live in, and the person in front of him can decide his life and death with a word.

He had seen with his own eyes how Yan Yunzhou treated those who came to assassinate him, he was just a big grudge who worshipped him, and he asked himself if he could not have the same treatment as his younger brother.

So who did Shuncai meet today? And what did you say? Why did Yan Yunzhou think so sure that he was from the palace as soon as he came back?

"Lord Wang, even if you want to convict me, you have to show evidence, Shuncai was indeed sent out by me, and I asked him to help me find two things.

As for the people he met in the former Houfu and the people in the palace, this doesn't prove anything, my father must be trying his best to find out the news in the palace now, and it's normal to see if he goes out to interrogate him. ”

Ning Yi reacted to the possible situation in an instant, he didn't know if Shuncai really said something, and even he didn't know if Shuncai was really with the original owner.
