"Get up...!"

Li Zhan came to his father's workshop... The workshop is in a bamboo room outside the courtyard, at this time Li Dafu, Zhang Hei, Zhang Shun, Zhang Wen, and Zhang Liang are constantly making wooden boxes.

Seeing Li Zhan come in, Li Dafu asked with a smile, and then began to work again.

"How many wooden boxes can be made in a day?"

Li Zhan asked.

"About three hundred... That one... Zhan'er, how much do you need? Li Dafu stood up and looked at Li Zhan and asked.

"The more the merrier, but for now, two thousand... We're going to get the business up and running first. Li Zhan smiled, then greeted his uncle and cousins before going out.

When he came outside, Li Zhan saw that his grandfather was bringing Li Sheng, Zhang Gong, and Zhang Jian to grind saltpeter powder.

The tool is the stone mill, probably in the Warring States period stone mill on the historical stage, it is generally believed that as late as the Qin and Han dynasties, the stone mill has been widely used by the people. The technology of grinding flour gradually matured, and delicious pasta dishes such as noodles and steamed bread were developed, and more and more Chinese began to use wheat as a staple food.

At the same time, those Europeans were still using the most primitive methods to make bread and eat it.

One, two, three, all shirtless, the muscles all over the body really made Li Zhan embarrassed, at this time Li Zhan also knew why he let his uncle's two sons push the stone mill, this muscular, it is a pity not to push the stone mill.

"Grandpa...!"

With a soft shout, Zhang Damao turned around and saw that it was Li Zhan, and immediately said with a smile on his face: "Zhan'er is awake, hey... I woke up too early, why didn't I get some sleep? ”

"Huh...!" Looking at the sun that was almost noon, Li Zhan smiled and said, "Don't sleep, get up and take a look, how much stone powder have you crushed?" ”

"Look...!" Zhang Damao took out an empty bag and said with a smile: "There is no more...!" ”

"Wow... Great work...! Li Zhan greeted Li Sheng, Zhang Gong, and Zhang Jian.

"Big brother... Cousin...! Li Sheng, Zhang Gong, and Zhang Jian also immediately smiled and gave Li Zhan a response.

At this time... Zhang Damao said with a smile: "It's just grinding some stones, what's hard, and these stones are not hard at all, right... Zhan'er, I actually saw such a stone on the mountain behind. ”

"Huh...?" Li Zhan was stunned for a moment, looked at Zhang Damao on the side and asked in surprise: "Grandpa... You can't be mistaken, right? ”

"How could you be mistaken... There are really a lot of them, but I didn't know what these were before, and if I did, I'd show you a piece. Zhang Damao looked very determined.

Li Zhan was also surprised.

Because according to Li Zhan's memory, the mountain Zhang Damao said was Wang Shunshan in the future, and this Wang Shunshan was a national forest park in later generations, and I haven't heard of saltpeter mines?

It's just that there is no future generation, it doesn't mean that there was no before, maybe it was picked up in a certain dynasty?

Thinking of this, Li Zhan looked at his grandfather and said, "Grandpa... Wait a minute, we'll go into the mountains. ”

................................

Wang Shunshan... The south is adjacent to the Qinling Mountains, the north is adjacent to the Bahe River, surrounded by blue water, and the scenery is charming. Wang Shun buried his mother here and got his name,

The poet Du Fu once wrote: "Languan is far away from a thousand streams, Yushan is high and two peaks are cold", Han Yu was degraded to Chaozhou and was blocked by heavy snow on the way through Languan, leaving the eternal quatrain of "where is the home of the clouds across the Qinling Mountains, and the snow hugs the Languan and does not move forward".

Li Zhan has climbed once, but this time is completely different from the last time, this time it is even more beautiful, because it is summer, and the green shade is stacked and cool... Fragrant trees, collar spring trees, golden maples, Chinese hazelnuts, rowans, antelopes, black bears, giant salamanders, etc... It's really breathtaking!

Li Zhan regretted that he didn't have a bow and arrow at home, otherwise, he would definitely be able to get some game and go back, follow behind his grandfather, and his younger brothers surrounded him in the middle.

After walking through a few woods and a few streams, Li Zhan enjoyed the scenery all the way, but Li Zhan's younger brothers have been carefully protecting Li Zhan.

So no matter how beautiful the scenery is, they don't want to see it.

"Zhan'er... It's right in front. ”

Zhang Damao in front grinned, followed Li Zhan and the others across a stream, through a mountain forest, and came to a flat mountain... Here, Li Zhan finally saw a large area of saltpeter mine exposed on the surface.

"Zhan'er... Isn't it this? Zhang Damao walked up to Li Zhan's side and asked as if he were meritorious.

"It's... Be...! Li Zhan smiled happily and said, "Grandpa... You're so godly, I just need this...! Great, our family will never worry about this lack in the future. Grandfather... How did you find out about this? ”

"Hehe... Coincidentally, about a year ago, a pair of nobles came to Lantian to play... I was going to find someone to go into the mountains, and then I was chosen, and gave me ten big money, and when they were hunting, they came here by accident, and I followed. ”

"God help me." Li Zhan grinned.

"That's nature... Zhan'er is a child of a fairy, of course the heavens will protect you,"

"Huh...!" Just when Zhang Damao kept touting his grandson, our classmate Li Zhan let out a soft 'huh', and he actually saw another exposed mineral on the other side.

After Li Zhan took a closer look, he shouted in surprise: "Rock salt...!" ”

Rock salt is stone salt, this thing is colorless and transparent, and when it contains impurities, it is light gray, yellow, red, black and other colors, and the glass is luster. It is a typical mineral of chemical sedimentary origin, which is often deposited in salt lakes and coastal shallow lagoons of various geological ages under dry and hot climate conditions, and symbiotic or associated with potash, carnallite, polyhalite, gypsum, anhydrite, miscanthus salt, etc.

Just when Li Zhan wanted to rush over, Zhang Damao stopped Li Zhan and said, "Zhan'er... What are you going to do? ”

"Grandpa... There is salt there. ”

"Salt?" Zhang Damao shook his head again and again: "Child... It wasn't salt, the stone looked like salt, and it had a little bit of salinity, but that kind of salt would kill you if you ate it.

You don't know... Last time, the second dog in Zhangjia Village died after eating this kind of stone. ”

"Haha...!" Looking at his grandfather, who was worried about him, Li Zhan suddenly laughed, and this laughter made Li Zhan's grandfather and younger brothers dumbfounded.

However, Li Zhan said hesitantly: "Grandpa... This is just a rock mine, of course, you can't eat it directly, there are a lot of toxic substances in it, but when I was in the fairy world, I learned how to use the poisonous substances in it to get out.

When there are no more toxic substances, all that is left in it is edible salt..! ”

"Really...!" Soon, Zhang Damao also showed a surprised expression, you know, this salt... But it's a good thing... At this time, Datang was seriously short of salt.
