After running for a while, Lu Qing remembered what she had come here for. She hurriedly checked the surroundings and sure enough, she found a dry puddle with a thick salt cap at the bottom. This was the origin of the biggest salt mine in the future, the precious potash mine.

After walking for a few hundred meters, Lu Qing found an area with fewer animal tracks and started to inspect the structure of the salt mines.

Not only was there the potash mine, there were also some gypsum that coexisted with the soda mine. If she didn't have to leave Yumen Pass, then the tofu factory could open again …

Lu Qing picked a few clean pieces of gypsum and soda and set them aside. She then started to clean up the huge salt cap, which contained a lot of sand. These were the first things she had to filter out.

Yu Mingchuan also came to help, but at first he couldn't tell the difference between soda and salt. Lu Qing taught him to identify it for a while before she finally figured it out.

By the time Faang Jiming and his entourage arrived, Lu Qing and Yu Mingchuan had already picked a pile of salt.

Lu Qing didn't see the flatbed, but she was a little puzzled. She saw that the group of people had brought their stuff with them, including the huge iron pot, the fine linen, and the charcoal.

"Defend your ears and ears. Let's do it here."

Yu Mingchuan explained as he held Lu Qing's hand.

Lu Qing nodded and then began instructing her men to gather firewood, build pots, and boil water.

These people were extremely quick. After a while, they were all ready to boil the water.

Lu Qing asked them to first throw the dirty salt block into the pot. After the salt block was dissolved, they would filter it with gauze and charcoal, burn it dry, and then use cold water and hot water for a few times. After that, they would leave the separated crystal block alone and burn it dry.

Some of what looked like salt was thrown away by Lu Qing.

While Lu Qing was making the salt, these people didn't even dare to blink for fear of missing anything. However, they were still confused. They didn't know why they would have to go through cold water and hot water repeatedly after cleaning it with charcoal gauze, or why they would end up with three different things …

Satisfied, Lu Qing tasted the sodium salt she separated. The bitterness was gone. Perfect.

"This part of the salt can be eaten. As for the rest, if I sprinkle them into the fields, it will help the crops grow. The rest that I threw away will be thrown away."

Everyone stared at Lu Qing in shock. Yu Mingchuan was the first one to reach out his finger and taste the salt Lu Qing had just eaten.

It was salty, not bitter, better than the salt they had eaten before.

"Hehehehe …"

A burst of deep laughter came out from Yu Mingchuan's mouth. Soon after, it became bigger and bigger, scaring the birds on the poplar tree away.

Although Faang Jiming was expressionless, his eyes revealed his thoughts. It was too bright.

Steadily, he walked over to the pile of salt and also tasted it. His face was filled with shock and ecstasy.

Liu Chen was naturally unwilling to accept this. He grabbed a handful of salt and put it into his mouth.

"We have salt!"

The group of people cheered. They grabbed the salt and put it in their mouths, but Lu Qing couldn't stop them.

Yu Mingchuan, who had stopped laughing, kept a smile on his face and pulled Lu Qing, who was trying to stop the guards from eating the salt, into his arms.

"Lu Qing, don't go."

Lu Qing's mind exploded when she heard this. This bastard was going back on his word!

"We agreed that if I solve the problem of your salt, you will let me go outside!" Lu Qing struggled as hard as she could, but this fellow's arms were like iron, they just stood there, not moving at all.
