With the ingredients, even if there is no formula ratio, you can always come to a conclusion by experimenting one by one! This is Yang Xu's method, find a piece of newly produced silk paper in the workshop, and write the words charcoal, sulfur, and potassium nitrate on it.

Then he threw the brush aside, although the words on the paper were not good, but they were still horizontal and vertical, Yang Xu looked at it, and was about to hand this over to Zhang Hong, but at this time he felt awkward no matter how he looked at it, charcoal, no problem, sulfur, should be able to understand, but potassium nitrate, this is a chemical name, I know it, others can understand it!

What is potassium nitrate? Yang Xu was also confused, when he was in chemistry class, he listened a lot and saw less, what the specific object was, he really didn't know, there was no way, search for memory!

After a while, he finally found the relevant one, and Yang Xu changed the potassium nitrate to saltpeter! But he continued to use his brain, and searched the memories of his previous life before and after, and now he feels sleepy, and his head is a mess!

"Lord, are you looking for me?" Just when Yang Xu was about to fall asleep, Zhang Hong entered the study!

"Zigang, you're here!" Yang Xu greeted, handed him the formula on the table, and said mysteriously: "I dreamed of an immortal last night, and he taught me the recipe for making gunpowder, but how many of these things need to be refined, you still need to find a Taoist priest to ponder and experiment!" ”

Zhang Hong held the silk paper, his face full of doubts, "Lord, what is gunpowder and how can it be refined?" ”

"Gunpowder is a powerful and extremely powerful one" Yang Xu wanted to explain, but his mind was confused, and he couldn't find any words to describe it for a while, so he was directly stuck! After half a ring, he said categorically: "You will know what this gunpowder is when it is refined, I want the most powerful and effective one!" ”

As he spoke, Yang Xu waved his hand again, "No, I'm too sleepy, I have to go to sleep for a while!" You go and get ready first! Then he walked out of the study by himself, leaving Zhang Hong confused!" What's the matter, my lord, it's mysterious! What kind of medicine is this gunpowder, and what is it used to refine it? Zhang Hong was puzzled, and at this time, Yang Xu yawned and came, as if it was a bright light in the fog, instantly pointing out the direction for him! Let him pause.

"I didn't expect that the lord was young, and his body would not be good! I even thought of finding some pills and refining pills to nourish and maintain health! Zhang Hong sighed in his heart. At this time, Yang Xu walked to the door, and as if he remembered something, he suddenly turned around and told Zhang Hong: "Remember, this matter must be kept secret!" Don't leak it out! ”

"Don't worry, my subordinates will be tight-lipped!" Zhang Hong blurted out immediately! Yang Xu nodded with satisfaction, and then left, Zhang Hong looked at his figure, his eyes were full of sympathy, "Lord, in fact, if you don't remind you, I also know about confidentiality, this kind of thing, it doesn't have a good reputation when it spreads!" ”

Another ten days passed, in these ten days, the progress of recruiting recruits made Yang Xu very satisfied, but the cost gave him a headache, just after lunch, Zhang Zhao found him to discuss the issue of money, it sounds like a discussion, and it is to complain and ask for money!

When the Xiongnu returned to Chang'an, Yang Xu couldn't be busy with a bunch of things at that time, so he proposed many changes, one of which was that all departments that needed money, don't look for him, just look for Zhang Zhao! And then in the newspaper!

The power of the household department is great, but Zhang Zhao has become sneaky, hiding when he sees people all day long, and occasionally meeting, as if others owe him millions of taels of gold! It makes people laugh and cry! No, he went to Yang Xu to make money again.

"Lord! Recently, the expenses have been too big, and the household department can't come up with the money at all, and the subordinates really have no choice, so they have to be cheeky to find the lord! ”

Zhang Zhao cried with a sad face, like an angry little resentful woman!

It was the first time for Yang Xu to see Zhang Zhao's expression, as if he had discovered a new continent, he couldn't help laughing, and felt that it was inappropriate, so he had to hold back! "Tell me, Mr. Zhang, where is there a shortage of money?"

Zhang Zhao counted his fingers and said to him one by one, "The first is to recruit soldiers, 70,000 horses have been recruited in the past half a month, these horses have to ask for money for their armor and weapons, Xu Huang is a tall general, and his tone is also big, so he directly asks me for 10,000 gold!" ”

Yang Xu endured! Continue to listen to Zhang Zhao!

"The 500,000 captives brought back from the grassland, although they are poorly fed and clothed, they have to ask for money, and Li Yan of the Criminal Department is not small, even if I want 5,000 gold!"

Yang Xu looked at Zhang Zhao's funny appearance, and couldn't help it, took a sip of tea, and pressed it! before continuing to motioned for him to continue.

"The school building is newly opened, the master wants money, the books ask for money, the students want money, and the facilities need money, although Lord Xu Jing is a literati, his tone is bigger than all of them, and his mouth is 20,000 gold! Let me get straight out of the door! Zhang Zhao said, his face was still indignant!

"Hahaha!" Yang Xu finally couldn't hold back and laughed directly! He smiled, but Zhang Zhao was stunned! "Why is the lord laughing!? Is it uncomfortable for subordinates to say? ”

Yang Xu hurriedly stopped laughing, pressed his hand, motioned for him to sit down, and then said, "Master Zhang, don't worry, I have already prepared gold for you, just take it!" ”

In Zhang Zhao's suspicious eyes, Yang Xu beckoned the guards and said, "You go to the Hero Building and call Yang Yun back!" ”

"No!" The guards took the order and left.

Yang Xu sat down instead, poured tea for Zhang Zhao, and smiled without saying a word! Seeing this, Zhang Zhao seemed to have a bottom in his heart, and he didn't complain!

Not long after, Yang Yunfeng hurriedly entered the door and said, "Young Master, what are you looking for me?" ”

Yang Xu glanced at him and asked, "How did you prepare the 100,000 gold I asked you to prepare a few days ago?" ”

Yang Yun arched his hand, "It's all ready, just wait for the young master to speak!" ”

Yang Xu smiled and said, "After you go down, you will hand over the money to Lord Zhang!" ”

"Yes! Master! Yang Yun responded, looked at Zhang Zhao next to him stupidly, and said in a daze: "This is the end?" ”

"It's over, otherwise what!" Yang Xu stretched out his hands and asked rhetorically.

At this time, a maid rushed in in a panic, knelt down in front of Yang Xu, and said, "Master, the second lady is about to give birth!" ”

"What?" Yang Xu exclaimed and got up! The maid trembled, but still said intermittently: "Soon after the second lady's lunch, she felt unbearable abdominal pain, and she was probably about to give birth!" ”

"Take me there!" Yang Xu hurriedly said! The maid hurriedly got up and led the way in front!

"It's been an hour, why hasn't there been any movement in the house!" Yang Xu was anxious outside the room like an ant on a hot pot, spinning around!

"Young master, don't worry, it'll be fine!" Yang Yun comforted on the side! Zhang Zhao was also not far behind him, the corners of his mouth opened and closed slightly, but he didn't speak!

"Why don't you worry, it only took less than half an hour for the cicada at that time, and now an hour has passed!" Yang Xu was anxious, and his airway was airway.

Yang Yun was also dumbfounded, he had never experienced this kind of thing, and he didn't know how to comfort him, so he had to keep his mouth shut and not speak!

At this moment, a huge sound roared, instantly spreading throughout the heavens and the earth, and then everyone felt a slight shaking! After that, there was no sound, and everyone was frightened and wondered, how could there be thunder on this sunny day?

Yang Xu was not surprised, he just paused for a second, and his mind was on Cai Yan in the room again! But at this moment, there was a sound of joy in the room. "It's out, it's out!"

And then there was another baby cry! Yang Xu's face finally eased at this moment! A maid came out of the house and reported good news to Yang Xu,

"Congratulations, sir, Madame has given birth to a little son!"

Zhang Zhao, who was behind him, stepped forward when he heard this, and bowed his hand, "Congratulations to the lord, this son should be thundered, and the future will definitely be extraordinary!" ”

Yang Yun also said happily: "Yes, young master, just after thunder, the little young master was born, this is the will of heaven!" ”

I like to listen to good words, and Yang Xu is no exception, smiling slightly, and said: "Master Zhang is serious, since Zibu has a relationship with this son, why don't you grow up to be his mentor?" ”

"The subordinates are shallow, and they are favored by the lord, so it is better to be respectful than to obey their fate!" Zhang Zhao didn't shirk it, so he happily accepted, and then said: "Since the little boy has come to the world, then the subordinates will go back to the household department first!" ”

"Good! You go back first, there are a lot of things to do! Yang Xu happily agreed, and then instructed Yang Yun: "You accompany Master Zhang and hand over the gold to him!" ”

"Yes! Master! ”

After the two left, Yang Xu waited outside the door for a while, and waited until the next person cleaned up the house before letting him in!

When Yang Xu entered the room, he first looked at Cai Yan on the bed, only to see that she was weak at this time, her face was pale, and there were sweat stains on her forehead!

"I'm sorry for you, Xiaoyan!" Yang Xu sat on the edge of the bed, held Cai Yan's hand distressedly, and said softly.

"Husband, these are what I should do!" Cai Yan said in a weak voice, "Let's take a look at our children first!" ”

Cai Yan reminded that Yang Xu took the child in the hand of the maid and held it in his arms, at this time he took a closer look and smiled at Cai Yan: "Our son is really different!" Zhang Zhao also said outside just now that this son will fall with thunder, and he will inevitably be famous all over the world in the future! So I even thought of a name! It's called Yang Lei! ”

"Didn't you say yes, my son was named Yang Zhen, and my daughter was named Yang Nan, why did you regret it!" Cai Yan's weak voice came!

Yang Xu was about to explain, Diao Chan entered the house, and when he saw Yang Xu, he said: "General Pei Yuanshao came to the study just now, and said that he wanted to see you, I told him that you were here, and he followed!" Now outside the door! ”

"Pei Yuanshao! What is he here for? Yang Xu thought to himself, and said loudly to the outside of the question: "Pei Yuanshao, if there is something to say directly outside the door!" ”

"My lord, Lord Zhang Hong of the Ministry of Industry asked the last man to send an urgent report, saying that the alchemy room had exploded, please come over!"

"What an alchemy room exploded! Does it have anything to do with me? Yang Xu felt inexplicable!

"Lord Zhang said that it was the alchemy room where the lord asked him to refine gunpowder! It exploded just now, and not only the last general heard it, but it is estimated that the whole Chang'an City heard it! ”

Hearing Pei Yuanshao's reply, Yang Xu's heart suddenly looked like an overturned soy sauce bottle, with mixed flavors! looked at the child in his arms, but he was secretly scolding Zhang Zhao in his heart, "What should happen to thunder, it's all nonsense, what the hell, it's labor and management that make people study gunpowder exploded!" ”
