Yang Xu looked at Cai Yan and said weakly: "I'll listen to you, just call Yang Zhen!" He turned back and told Diao Chan, "Cicada, you take care of Xiaoyan, I have to go over beforehand!" ”

Diao Chan nodded, Yang Xu glanced at Cai Yan again, turned around ruthlessly, and went out without hesitation!

"Where is the alchemy room, take me there!" Yang Xu asked Pei Yuanshao with a dark face! The latter was a little scary, "In the western city!" "Then lead the way! Out of the mansion, stepping on the horses that had come from the guards, the two went straight to the alchemy room.

The alchemy room, now there is no shadow of the room, there are broken bricks and tiles all around, seeing that Zhang Hongzheng is personally organizing people to clean up the scene, Yang Xu dismounted and walked over.

"What about the alchemist? Call him here! Yang Xu shouted.

"My lord! Alchemist he," Zhang Hong resigned, and replied half a sentence, "What's wrong with him?" Yang Xu asked again!

"His bones are gone in the explosion! However, "Zhang Hong said half a sentence again, which made Yang Xu impatient! "Zigang, why have you become intermittent, grinding and chirping, and you have something to say!"

"But we found his Dantong! Still alive! "Zhang Hong is also weak-hearted, Yang Xu's confession was originally going to be kept secret, but now everyone knows about it!

"Call Dantong, I'm going to ask him!" Yang Xu said angrily!

Zhang Hong motioned to the soldier next to him, and in less than a minute, he brought a child about ten years old, this child's face was blue and purple, and his eyes were full of horror!

"Little friend, how much charcoal and sulfur did the Taoist priest use to fall to the ground?" For the child, Yang Xu's tone was a little gentle.

"My lord, the immortal master used half a bucket of sulfur, a bucket of charcoal, and three buckets of saltpeter, and then put it in a large pot to fry, and it began to smoke when it was fried! The immortal master said that it was not enough firepower! Let me go get some firewood! As soon as I went out, the house blew up! Dan Tong said, his mouth trembling, a little frightened.

After Dantong finished speaking, Yang Xu felt that his pores were cold, how much is a bucket, ten buckets and one stone, one stone is converted into about 60 catties in later generations, and one bucket is 6 catties, according to this ratio, the gunpowder prepared is more than 30 catties!

30 pounds of black powder! Yang Xu felt that this Taoist priest who refining gunpowder had died unjustly, and it was even more extravagant!

"Why does he put so much at once?" Yang Xu asked again!

"When the immortal master used the Dan furnace for the first few alchemy attempts, he was not satisfied with the refining because the effect was not good, and he felt that the reason was that the dosage was not enough! That's why I put so much this time, how could I have thought of it" As he spoke, Dan Tong actually cried out loud!

"The Taoist priest told his subordinates about this, and he successfully refined gunpowder a few times, and after he tasted it, he felt that the effect was a little worse, so his subordinates asked him to refine gunpowder again!" At this time, Zhang Hong interjected a sentence next to him!

Hearing Zhang Hong's words, Yang Xu grabbed a keyword, tasted it, and suddenly looked at Zhang Hong, his eyes widened incredulously, "You mean, that gunpowder was eaten by a Taoist priest?" ”

"Yes, after the Taoist priest ate it, he said it tasted good!" Zhang Hong replied strangely.

Yang Xu suddenly felt that thousands of grass and mud horses ran through his mind, and later generations compared a person to a short temper, saying that he had eaten gunpowder, but he didn't expect that there were really people who ate gunpowder, and gave a good review, the taste was not bad!

"Who said gunpowder was edible?" Yang Xu pronounced this sentence word by word!

"Isn't gunpowder medicine, can't you eat it? Is it for external application? Zhang Hong asked puzzled.

Yang Xu was speechless for a moment, is gunpowder medicine, it seems to be really medicine, but it can't be taken or used externally! Yang Xu pointed to the surrounding ruins and walls, and said to Zhang Hong: "Gunpowder is used to explode, you see, this alchemy room is blown up thoroughly!" Therefore, this gunpowder is mainly used in warfare, not in medicine! Got it? ”

"Got it!" Zhang Hongmuran nodded, for him, this name is too misleading, it is obviously the name of medicine, but it is a sharp weapon used to kill people! Zhang Hong looked around again, this scale, this scene, really responded to Yang Xu's words at the beginning, it was extremely powerful!

"Lord, then do we need to find a new Taoist priest to refine gunpowder!" Zhang Hong asked.

"Lian, of course you have to refin, but it's not a Taoist, it's our craftsman!" Yang Xu replied affirmatively.

"Ahh Craftsman? Zhang Hong exclaimed, a professional alchemy master like a Taoist priest has been blown to pieces, if it is a craftsman, then it will not be blown up all over Chang'an!

"Just now, Dan Tong said that I have already guessed the approximate formula! If you refine it according to this ratio, you will definitely succeed! Yang Xu said confidently. However, you have also seen the disadvantages of gunpowder, that is, it is very dangerous, it will burn immediately when you see a fire, and it may explode! So be extra careful when refining! ”

Looking at Zhang Hong, who was dazed, Yang Xu pounded his forehead and said dejectedly: "Forget it, I still personally guide the craftsmen, so as not to make any noise and make people worry!" ”

"My lord!" At this time, Zhang Hong hurriedly stopped, "How can the lord's golden body be put in danger!" ”

"What a thousand gold bodies, what dangerous places, gunpowder is very dangerous in the eyes of those you don't understand, for me, although dangerous, but at least it can be controlled!"

Zhang Hong wanted to persuade a few words again, but saw Yang Xu waving his hand, "Don't grind, it's so decided, you hurry up and clean this up now, don't let too many people notice the abnormality!" Remember, this is a secret! ”

"Subordinates obey!" Zhang Hong responded, and then arranged for the soldiers to go.

"Pei Yuanshao, you also go to help!" Yang Xu said again, and Pei Yuanshao immediately received the order!

Looking at the busy Zhang Hong, Yang Xu is now a little skeptical of his decision, at that time he valued Zhang Hong's city-building stunts, so he put him in the position of the head of the Ministry of Industry, now it seems that he is only very experienced in how to arrange artificial materials and speed up construction, as for invention and creation, he doesn't know anything!

Yang Xu thought back to the inventors and creators of the Three Kingdoms, thinking about it, there were only four, Zhuge Liang and his wife counted one, Liu Ye counted one, invented the thunderbolt car, the real leader, or the last person, Ma Jun.

Ma Jun, a Fufeng man in the late Han and early Wei dynasties, was a master of machinery in ancient China, skilled in the invention and creation of instruments! People commented on him as "the world's most famous skill"!

But it's too early now, and it is estimated that Ma Jun has not been born yet! Liu Ye has already voted for Cao Cao, and he only invented the thunderbolt car, he is not a famous craftsman, Zhuge Liang and his wife, they are now more than ten years old, and they don't know which corner to play with mud!

With such a thought, Yang Xu found that there was no Fang Ming family in this era, and immediately sighed: "With gunpowder, what about the cannon, I didn't learn how to make a cannon when I was in school!" ”

If you want Yang Xu, who only knows a little bit of the principle, to build artillery, and then use artillery fire to hit the enemy from a long distance, it can only be achieved in the Year of the Monkey, it is better to directly raise a knife and cut it now!

"There is no hope for cannons, let the craftsmen figure it out for themselves, but grenades can still be made! It's easy! Yang Xu thought about it from another angle, it is really possible to make grenades, although it may be a little rougher!

Make a hollow iron ball, then fill it with gunpowder, plug the hole, leave a lead, and the simplified version of the grenade is made, but how to do it, such as leaving a handle, not throwing a lead ball, and the problem of the lead, etc., all need to be considered.

However, with this idea, Yang Xu was in a happy mood, stepped on the horse, and went back to the house to clear his mind.
