"But, Tou Ding, don't we have a salt lake in Hanmenguan? How can there be a shortage of salt? “

Mu Qingli was puzzled, she clearly remembered that when she entered the pass, there was a clear lake on the horizon, and there was a circle of silver-white salt belts around the lake, like a beautiful collar on the salt lake, she had traveled to the salt lake in her previous life, similar to the lake in Hanmen Pass, and Hanmen Pass is located at the junction of the Gobi and the plains, and the climate has been dry all year round.

Ding Gangtou said strangely: "You kid still know about salt lakes?" Then he shook his head and sighed: "The salt of the salt lake is called green salt, it is salty and bitter, and it is poisonous, and it is inedible at all. ”

"Tou Ding, doesn't anyone know that green salt can only be eaten after purification?"

"What? Purification? What is the meaning? Ding looked puzzled.

Mu Qingli suddenly realized that the problem was. Untreated green salt contains a lot of minerals, phosphate and other impurities, is not allowed to be eaten directly, if directly eaten will cause great harm to the human body, in this era, it is obvious that there is no purification technology, so it will cause the cold door to guard the salt lake but lack of salt.

Mu Qingli said helplessly: "Ding Guy, eating green salt without treatment will indeed cause harm to the human body, but after purification, it will be no different from ordinary salt, and it can be eaten normally." ”

When Ding Gang heard this, he grabbed Mu Qingli's arm excitedly and said, "Hearing you say this, will you purify this?" ”

Mu Qingli was caught in pain, and she didn't dare to struggle, so she had to nod and say, "I will." She remembers visiting the local people during her travels to see the process of making a handful of raw salt, so she really knows how to do it.

Old man Ding seemed to be in disbelief, his eyes widened, if the salt of the salt lake could be used, then, such a large lake...... Old man Ding didn't dare to think about it anymore, his eyes were shining, he grabbed Mu Qingli's arm tightly, as if he was afraid that Mu Qingli would escape, and he didn't speak very neatly and pulled Mu Qingli to the city, "Okay!" Good boy, you go with me, you tell the general how you make salt, if ...... If you can really succeed, you will be a great hero of the Zhendong Army! “

Mu Qingli didn't expect a simple salt-making method to make Ding Gangtou so excited, and he was staggered by Ding Gangtou for a while, so he was embarrassed.

It didn't take long for Ding Gangtou to pull Mu Qingli away from the military camp and come to the general's mansion in the city.

While Ding Gangtou was negotiating with the soldiers guarding the gate, Mu Qingli tilted his head and looked at the general's mansion in this cold gate, saying that it was the general's mansion, but in fact, it was bigger than an ordinary house. Hanmen Pass has a large area of green and yellow grass slopes and clear lakes, there is no Gobi-like desert desolation, the dwellings in Guanzhong are generally short mud embryo houses, and the mud embryo houses of the general's mansion are very large, the courtyard in front of the house is a martial arts training ground again, covering a wide area, compared with others it seems to be much more majestic and magnificent.

After Mu Qingli finished looking, the soldiers guarding the courtyard gate also ran into the room to tell the general, and then hurriedly came out to let Ding Gangtou go in and reply.

Ding Gangtou pulled Mu Qingli, crossed the courtyard gate and passed through the martial arts training ground, and entered the lobby facing the courtyard gate, where a desk was placed on the left side of the hall, and the head of the Zhendong Army, General Zhao Ziyi, was sitting on the Taishi chair behind the desk.

"Ding Yimao, the leader of the food battalion, meets the general!" Ding pulled Mu Qingli and respectfully saluted Zhao Ziyi.

Mu Qingli finished the military salute with Ding Gangtou, and couldn't help but be stunned when he looked up!
