Traveling through the Tang Dynasty: Peerless Village Girl

Chapter 164 Saltpeter
　Now, apart from taking care of Tang Mu, it seems that there is nothing to do, and Mo Feiyi also feels quite leisurely.

On this day, after Tang Mu had taken the medicine, he lay down and fell asleep, and Mo Feiyi took Xiaoyu for a walk on the streets. He had been in Chang'an for so long, and apart from his busy schedule, he really didn't take a good look at the market in Chang'an.

Pedestrians are bustling with each other on the street, and there are many shops on both sides of the street, with a dazzling array of goods, showing the incomparable prosperity of the Tang Dynasty.

Today is the market day, and there are many people going to the market. The wide streets are full of people, which looks abnormally crowded, and some sections even have traffic jams.

He and Xiaoyu ate a pancake, a bowl of mutton soup, and bought some snacks at a snack bar by the roadside. Seeing that the streets were crowded, Mo Feiyi chose the alleys and alleys with fewer trips to go home for convenience.

"Hey, miss, look, it's not winter yet, how can there be snow and frost on this wall?" Xiaoyu pointed to a wall with a fussy expression.

There was indeed a layer of white frost on the old wall, and a few naughty children scraped it off with wood chips to play with.

Mo Feiyi smiled and said, "That's not Xueshuang, it's nitrate."

In the late Tang Dynasty, black gunpowder had already appeared, but it was not used too much in military affairs.She also saw records in "Tiangong Kaiwu" by Song Yingxing in the Ming Dynasty that Sichuan, Shanxi, and Shandong produced the most nitrate, and there were also nitrates that emerged from the earth walls, called wall nitrate.

Xiaoyu was curious, so she ran over to ask some children for a little nitrate to play with.

"Hey, haven't you grown up yet?" Mo Feiyi felt amused, and continued walking. After walking a few steps, his heart skipped a beat.

Xiaoyu just lowered her head and played with the wall gun in her hand. How could she think that the lady stopped suddenly and almost bumped into her head, "Miss, what's the matter with you?"

Mo Feiyi thought of Tang Mu, he had a worried and painful expression all day long, and he often had nightmares, worrying that those killers would come to his door.

Some things have to be faced sooner or later. To help him get rid of the nightmare, he must get rid of the source of fear in his heart. Mo Feiyi thought of making black powder.

She read "Heavenly Craftsmanship", and she was curious about the purification and production methods of nitrate. The mixture of nitrate, sulfur, and plant ash is black powder, but the specific ratio, she can't remember. Cleared up.

Returning home in a hurry, Mo Feiyi called the fake Baoyu and told him to find a way to buy some saltpeter and sulfur.

Sulfur is sold in the market, but nitrate is not available. Mo Feiyi told him about the nitrate, and the fake Baoyu rolled his eyes, and he had an idea in his mind.

He asked someone to bring the leather bag, bought a lot of candied gourds along the way, and came to the place where Mo Feiyi saw the wall, and the children were still scraping the wall with wood chips to play.

Fake Baoyu played with the hulu candies in his hands, with a wretched smile on his face, "Kids, do you want to eat hulu candies?"
