Fangjiazhuang.

After Fang Yiai came back, he was idle, he was not a hard-working person, invention was not a momentary effort, and the manufacture of gunpowder was not in a hurry.

However, what he didn't expect was ......

Before noon, Li Tai hurriedly ran back, obviously to make gunpowder, "Master, I heard my father say that you will invent something that can destroy the Liangyi Hall by yourself, can you participate in it?" ”

Li Shimin figured out the personalities of the two.

Fang Yiai is an ironclad lazy master, and he is eager to see this real thing, so he leaked the news to Li Tai.

With Li Tai's fanatical attitude towards science, when he heard that there was such a miraculous thing, he would definitely not be able to resist his curiosity and would take the initiative to come over.

In fact, it is also Li Shimin's prevention!

Of course, he is not at ease with such a powerful thing, it is only in the hands of one person, even if this person is someone he trusts.

"You're here, who will be responsible for the official road."

For Fang Yiai, it is good for Li Tai to get involved, so that there will be tools to use, but Li Tai is still shouldering the burden of hardening the official road, so he has such a question.

"Master, don't worry, I have my junior brother to take care of it, if there is something that can't be handled, he will naturally not come to me." Li Tai obviously arranged everything, followed the example, and threw the matter to his junior brother.

It's just that Susan, who came in to deliver tea, covered her mouth and chuckled, thinking in her heart: "It is worthy of being a master and apprentice, this skill of stealing and playing tricks is really in the same vein." ”

"In that case, you can stay, don't miss the official business." Fang Yiai gave a word, which can be regarded as a promise.

"Master rest assured, disciple knows in his heart." Li Tai nodded in agreement, he had an infinite interest in new things, and couldn't wait to urge, "Master, when are we going to do it?" ”

"Don't worry, it's noon soon, let's have lunch first."

"Oh!"

Li Tai immediately calmed down, looking forward to the start of lunch soon.

After lunch.

Fang Yiai was lying on the recliner, and in the face of Li Tai's urging, he said unhurriedly: "Don't be in a hurry to make gunpowder first, and before that, the teacher will give you a lesson." ”

Originally, after listening to the first half of the sentence, Li Tai's eyes darkened, and he thought that he was looking for some reason, but when he heard the back, he was happy again.

"The discipline we want to talk about today is called chemistry, which is a branch of science that studies the composition, nature, structure and change laws of all things, and creates new material ......."

As for the specific action of making gunpowder, leave it to Li Tai, a tool man, to do, "You first prepare sulfur, saltpeter, charcoal, and gunpowder formula: one sulfur, two nitrate, and three charcoal." ”

The recipe for black powder was learned in the chemistry textbook of junior high school in the previous life.

In fact, in today's world, gunpowder has long existed, but the best formula should not have been experimented with, after all, Taoist priests like to add some messy things to alchemy.

"Everything you come by yourself must be kept secret and not known to others." Fang Yiai admonished.

"The disciple remembered."

Li Tai knew that the matter was serious, and he clenched his fists and said solemnly, so he couldn't wait to leave and start preparing.

However, he was stopped by Fang Yiai, who turned into an old mother and told him repeatedly; "This thing is very dangerous, don't use it in the laboratory at home, remember not to have open flames, don't wear silk clothes, preferably cotton clothes......"

Because of his love and love, the family vacated a room as his laboratory. Li Tai did the same, and built a room in his palace.

Of course, the compound is the base camp, and naturally there is also his laboratory, which is all made of cement.

After the glass was fired, he customized a lot of strange bottles and jars, which were actually beakers, flasks and the like, which gave him the appearance of a laboratory.

"Whoa!"

"Forget it, you'd better wear sackcloth."

Fang Yiai remembered that Datang had not yet planted cotton on a large scale, let alone used it for clothing, and the so-called cotton at this time was actually silk cotton or cotton silk, which would inevitably not produce static electricity.

"Whoa!"

This time, Li Tai was not stopped again, and left in a hurry, and began to prepare the materials for gunpowder.

……

Fang Yiai shouted excitedly: "Qiao'er, go and invite Uncle Wen Quan to come over!" ”

He was talking about cotton.

In Datang, the rich wear mink fur in winter, and they don't feel a little cold, so he ignores this point because he is full and doesn't know that hungry men are hungry.

However, when he can, he will not be stingy to lend a hand.

Especially after meeting the Japanese Mission, his mentality has undergone a slight change, no longer it is not about himself, he is born as a Tang Dynasty, how can he not care about himself, his own destiny is closely related to this land.

Of course, the premise of all this is that he does not need to go into battle himself.

It's too late to plant cotton now, but down jackets can be done to benefit the people of the world, he doesn't want to delay more time, and there is still money to be made.

After a while, Fang Wenquan followed.

The movement made by Fang Yiai also recruited Susan to see what whims Xiang Gong had.

"Uncle Wen Quan, you ask the merchants of the Western Regions to see if you have seen a white plush plant with flowers, if so, buy some seeds and come back, I will be of great use in the future."

"Also, the people in the village are idle, I will arrange a job for them, go to ten miles and eight towns to collect duck feathers and goose feathers, as for the price, you can negotiate it yourself."

Fang Yiai took a breath and put forward all the requirements.

"Alas! Good! I'll do it. Fang Wenquan was on the side, nodding vigorously in agreement.

What the hell is Fang Yiai, he doesn't know, and there is no need to understand it all, Erlang's thinking, it is difficult for people in the world to catch up.

But what he ordered must not be a trivial matter, he just has to cooperate fully and do his best to do it.

"Actually, we can also set up a farm in the village, specializing in raising poultry, meat can be bought, and feathers will also be useful when the time comes." Fang Yiai added.

"Okay, I'll talk to someone later."

Fang Wenquan hurriedly wrote it down, this is to help Zhuang get rich, how can he not be serious.

However, at this time, Susan next to her said coldly, "The kind of plant that Xianghao said earlier, the concubine should have seen it." ”

"Really?"

"Can it be, the flowers are white and fluffy, soft to the touch, and there are many small black seeds."

"It shouldn't be wrong, where has the lady seen it?"

Susan smiled and said, "That's a kind of flower, called: Bai Diezi, a rich and noble family in Chang'an, there are seeds." ”

What Fang Yiai didn't know was that cotton was introduced to the Central Plains during the Northern and Southern Dynasties, but most of it was planted in the frontier, and it was planted as an ornamental flower in the Tang Dynasty.

"Haha! The lady is really a lucky star. ”

Fang Yiai was excited, and hugged Susan, "Let's go! "Kissed it.

He also thought that he would have to wait for the merchants of the Western Regions to bring it back, so it would be another year, so he hurriedly instructed: "Uncle Wen Quan, you go buy some seeds." ”

Although he is very familiar with Fang Wenquan, no matter how he says it, he can be regarded as an elder, Susan suddenly blushed with shame, patted her husband coquettishly, and ran away with her head down.

"Erlang, I'm going to get busy with nothing."

"Uncle Wen Quan, you're busy."

Fang Wenquan smiled at his uncle and left the house to work. Living to such an age, it is not strange to see anything, but I am sincerely pleased with the love of the young couple.

……

Saltpeter, sulfur, charcoal, I don't know what is scarce, go to any medicine store, you can buy all three, not to mention that they still open saltpeter mines.

It didn't take long for Li Tai to get his things done and come back.

The little fat man was sweating on his head, but there was a light in his eyes, not only did he not feel tired, but his face was ruddy and excited.

He has a strong interest in this kind of scientific invention, and he can't wait for it, "Master, so the disciples of the East and West are ready, and they are placed in the laboratory director of the Miscellaneous Academy, how can it start?" ”

"Alright, let's go now!"

Fang Yiai sighed, finally got up, and went to the courtyard with Li Tai.

Miscellaneous courtyard.

Although the laboratory specially prepared for Fang Yiai, although it is located in the corner, there is a spacious courtyard, and it is also one of the places with the highest security level in the courtyard.

As soon as they entered the house, they both changed into sackcloth, but the room was heated, so they didn't feel cold at all.

Li Tai put the three bags on the table and asked, "How do you want to get it?" ”

There are apprentices, this kind of dirty work is tiring, and he should not use the house to do it, he casually instructed, and sat down on the side, "First crush the three into powder." ”

"Whoa!"

Interest is the source of motivation, under this premise, Li Tai will not feel tired, let alone troublesome, and immediately start grinding.

"Don't put the powder together, it's dangerous!"

When Li Tai was about to start grinding the second one, Fang Yiai reminded him in time, and he immediately changed his position.

"Master!"

I don't know how long it took, Fang Yiai was about to fall asleep, Li Tai called him, he wiped the side of his mouth and put on makeup, "Finished grinding?" ”

There were three tables separated in the room, each with a pile of powder on it, and Li Tai's fair and fat face became a flower cat face.

Without Li Tai to speak, Fang Yiai instructed him, "Okay! Mix the three in proportion and put them in a clay pot...... Don't do so much, less yet! A little less! ”

"Let's go, let's try outside!"

Soon after, Fangjiazhuang heard a "boom", and the farmers hurried out to see what was going on, but they didn't see anything.

And then......

All kinds of rumors are disturbing!

"In winter, there is thunder in dry land!"

"There must be some amazing monster that God has chopped it!"

"I don't know if I'm killed? Don't come out and harm people! ”

……

Miscellaneous courtyard.

Fang Yiai and Li Tai hid in the house, and were shocked to a burst of tinnitus, like two bear children, the house is an all-cement structure, and the defense ability is extremely strong.

"It's so powerful!" After a brief loss of consciousness, patting his ears, Li Tai jumped up excitedly, "Success!" Gunpowder has been made! ”

In the courtyard, in the corner of the house in the courtyard, a hole was blown into the ground.
