Yang Shouli was the kind of person who treated men and women as if they were completely different people. In his eyes, women could only take charge of butlers and their children.

He didn't say anything, but only locked up his room. He walked over, picked up the bowl of tea, and gulped down a mouthful of it as if it was white water.

Xie Jingxi looked at him curiously. This Master Yang's hair was not dirty, it was not far from here, she had probably washed herself today, and even though his hair was disheveled, it was not combed neatly like most people's, and was still on the top of her head. This was fine, but his dry hair was covered with a layer of fine dust. It was unknown if she had been blown away by the bottom of the pot; her face was covered with dust, making him look extremely unsightly.

Xie Jingxi took a careful sniff, which seemed to have the smell of saltpeter and sulfur, could it be that this Master Yang liked to set up cannons inside the house?

"Today, I brought Jingwan here to meet you, and this is the person you mentioned, Master Yang."

Xie Jingxi could see that he was not very enthusiastic, hence she only nodded politely, "Master Yang, I was presumptuous of you."

Mistress Yang prodded Yang Shouli with her elbow, "What insolence? The only reason you guys are here is to treat us as your friends, ignore him. He only has this kind of dead face all day, stop acting like he owes you money."

Yang Shouli glared at her fiercely, "I was just thinking, what do you know about women?!"

"I don't think I know what's good for me. You just fiddle around in there like a demon. Can you eat it like a meal? If it wasn't for me, you would have starved to death."

This really made Yang Shouli speechless, although he was a proper level five official, his yearly tribute was only a hundred and eighty gold, not to mention, it was not even enough for a month's worth of food and drinks. He did not like camping, so he did not have any extra income, but of course, he did not have any connections with other people either.

If not for Mistress Yang who knows how to live, he would have really starved to death in his life. Yang Shouli had nothing to say, he could only hold in his anger, turned around and ignored her, and said to Gu Yun: "I've thought about the one you mentioned to me last night, and I still don't understand it. The key thing is that the ratio is not easy to grasp, but I tested it once just now, and it was not satisfactory.

Gu Yun didn't come here to see him do this, so he naturally didn't have any objections. But since he wanted to bring Xie Jingxi along, Yang Shouli had some objections, but the words that Mistress Yang had said after starving her entire life was still in his ears. In the end, she didn't dare to say that she was scolded, so he could only allow her to follow.

Yang Shouli brought them to a small hill at the back of the courtyard. Xie Jingxi could roughly guess what he was going to do, and saw that Yang Shouli had brought a few bags of medicinal powder and a few cannon fodder, which he obviously brought himself. It was extremely simple, he placed all of the cannon fodder next to different mounds.

"These are the formulas that I just modified. Let's give it a try for now, but in the end, it still needs to be decided based on the structure of the fire rod and its actual power."

Xie Jingxi had been looking at it curiously, she did not expect Yang Shouli to have such a talent. She did not have Gu Yun's experience and ideas in this area, she only felt that it was fun, and did not really expect Yang Shouli to research anything that could shock the world, she simply treated it as a pleasure to look at.

When Yang Shouli ignited the cannon fodder, Xie Jingxi seemed to have understood where their passion lay. This was indeed not a normal plaything used for fun, although Yang Shouli did not use much gunpowder, but the shock from the explosion shocked Xie Jingxi a little, if this thing was used on the battlefield, then its meaning would be different.

Of course, Xie Jingxi didn't know at this time that he was going to research even more exquisite fireballs as well. She was already filled with admiration as she said in a low voice to Gu Yun: "Looks a little interesting."

Gu Yun was originally afraid of her, so he brought her a little further away and covered her ears affectionately. However, Xie Jingxi did not give way in the face of his embarrassment, and seeing that she was not afraid, Gu Yun brought her in a little more.

"How about it? It's fun, right? This is a game that you can't watch no matter where you go."

Yang Shouli shook his head as he walked over, his face covered in dust, "It's still not satisfactory. This power is far from what I imagined, even if we put it in the Fire Rod Cannons, I'm afraid its effects are limited."

Gu Yun comforted her: "Take your time, if there is anything you need my help with, just say it, it is not a one-day affair, you have already done very well."

Yang Shouli sighed, and then noticed that Xie Jingxi seemed to be a little closer to him, "This is not a joke, you don't feel the slightest bit sorry for a lovely wife like me."

"It's okay, Xi has guts."

Xie Jingxi laughed along with him, "It's alright, Master Yang. I am not that delicate, but you have given me a whole new level of respect for you."

Yang Shouli felt embarrassed from his praise, and dejectedly waved his hand, "Sigh, don't mention it, it's nothing." As he spoke, he rolled up the cannon battle paper. "This is just a small matter. If it's useless, I can only use a shotgun."

Xie Jingxi looked at the powder in his hand and curiously walked over. Just as she was about to pick up a bag of powder to smell it, she was stopped by Yang Shouli as if she was facing a great enemy, "Ah, this is not good, this is not fun, you better be careful not to scatter it."

Xie Jingxi laughed, "That's nothing to worry about, it's just saltpeter and sulfur. If I were to light it up with a puff, it would be good."

After being choked by her, Yang Shouli also felt that he had made a fuss over nothing, but he was also unhappy to see her touch these things.

Xie Jingxi not only smelt it, she even used her hands to pick it up for a long time, causing Yang Shouli's heart to hang in her throat. She didn't know why this tender young lady would be so interested in this thing that could suffocate people.

"Although I don't know much about it, I know that the basic gunpowder is made up of saltpeter, sulfur, and charcoal powder in proportion." Xie Jingxi explained slowly, and Yang Shouli could not help but listen, "I remember that I once read a random book, and wrote a few words in this area. I only remember that it seemed that the selection of these raw materials could also affect the power of the gunpowder explosion, and from the looks of it, the color of the materials used by the Lord were not good, and there were even some faint impurities, which was probably because they were unsatisfactory."

Yang Shouli sighed: "There's no other way about it, all that can be bought on the market right now are these kinds of things." Even though she didn't have a constructive opinion, her words had already made him have a whole new level of respect for his. "It seems that you understand medicinal pills?"

"I know a little about it, but it's all from the books. I happen to know some purification methods, but I've never used them, so I don't know if they're useful. If you need them, I can write them to you."

Yang Shouli opened his eyes wide, he looked at Xie Jingxi like she was a god, "You actually know the purification method? "That's great. It doesn't matter if it's useful or not, we have to try. We have to try." Yang Shouli was a little excited, he patted Gu Yun's shoulders and did not say anything for a long time, "Your wife, you have eyes, it's really great, I have to quickly get her to write it down."

Xie Jingxi was overwhelmed by her favors, when Yang Shouli did not take her seriously, he did not take her seriously, but this sudden enthusiasm was too much! Gu Yun simply smiled from the side, but did not even bother to say a word, he was so angry that Xie Jingxi rolled his eyes.

Yang Shouli was no longer there in Yang Shouli's eyes, he chased after Xie Jingxi asking all sorts of questions, and in the end even addressed him as mister, "Thank you, Mr., can adding wolf poop really cause the gunpowder to go against the wind? "Can Kui Ye really increase the explosive power .."

Xie Jingxi was afraid that if she ran away, she would not be able to find her. She really wished that she could help her search Xie Jingxi's body and stomach, and only let her go after the sun had set. Mistress Yang was embarrassed, so she wrapped up a lot of dry vegetables for them and sent him away apologetically.

On the way back to the Marquis Mansion, Gu Yun massaged Xie Jingxi's shoulders, "It's really been hard on us Xi today."

Xie Jingxi rolled his eyes, "Do you still dare to introduce a few more ridiculous people?!"

Gu Yun laughed slyly, "How would I have known that my wife would read so many books and even know about the gunpowder? I did indeed want to bring you here to enjoy the show."

It's just that the information he has access to is limited, and just relying on his own grinding alone is already very rare. If what I said is helpful, then it might actually be possible, and if it wasn't said that the coastal strife from before was very severe, if we had an advanced firearm, what would we have to fear? "Su Yun said.

Gu Yun smiled meaningfully, "I hope that I can let you have your word."

When she returned to the Marquis Mansion, it was already dark. Xie Jingxi was just about to tell Ming Yu to prepare water for a bath when she saw Zhao Zhang waiting outside the courtyard, as if there was something urgent.

"Master, the King Jin has sent a message, telling you to go quickly." Zhao Zhang was here, so he couldn't speak too carefully. Gu Yun frowned, "I understand."

"It's so late already, why don't you hurry up and go. I don't know if you'll be able to come back for dinner, but I'll keep it for you." Seeing that she had matters to attend to, Xie Jingxi exhorted him a few words before returning to his room. Gu Yun did not return to his room, instead, he turned around and headed straight to the King Jin Palace.

"Master, King Jin has been searching for you everywhere since afternoon and has not been able to find you." Master, King Jin has been searching for you since afternoon.

Gu Yun muttered to himself: "Everyone has been keeping an eye out for the past few days, as for Madam, please send someone to guard her place well. Don't say too much, don't make her uncomfortable."

Zhao Zhang paused for a moment, he felt that his actions now were different from before.
