Although Tao Qing felt aggrieved, he still led a thousand soldiers and set off towards the unknown north.

The morale of the soldiers along the way was not very high, after all, this time it meant that they had left the elite soldier sequence from now on, and their treatment would naturally be reduced a lot.

They are usually no worse than others in training, and their head skills on the battlefield are not less than others, so why should they look down on people?

The blame for this is that Tao Qing chose himself.

Tao Qing led this grumbling military horse, according to the location marked on the map given to him by Liu Ping, Xiaoxing stayed overnight, and traveled all the way north, as if rushing to the execution ground.

The farther north they went, the more desolate they became, and their hearts sank.

Dingbian has the saying of "Yuyan in the east, Ganliang in the west, Huanqing in the south, and the desert in the north", which is already on the edge of the desert, and in this post-Han era, it is already regarded as a border.

When they arrived, they saw the barren and uninhabited environment around them, and their hearts sank to the extreme.

"General, this place is so desolate, are you sure that this is what the lord is talking about?" A pro-soldier asked Tao Qingdao with a bitter face.

Tao Qing lowered his head and carefully looked at the map, nodded and said, "Judging from the picture, it should be right." ”

"But there is not even a ghost shadow here, the lord is pampered, he should not have been here, how can he know that salt can be produced here?"

"Yes, if we dig for a long time and there is no brine underneath, wouldn't we be busy in vain?"

"You stupid, if we really can't dig up the brine, won't we be able to go back?"

"That's right! It makes sense. ”

The soldiers figured this out and immediately jumped for joy.

Who wants to stay on the edge of this desert all day and eat sand?

If they dig a well here and can't dig out the brine, then they are not to blame.

Of course, they can return to Chang'an justifiably.

"Don't make any noise, let's start quickly," even Tao Qing felt that what the soldiers said made sense, so he said in a loud voice: "Whoever has dug a well at home, hurry up and choose a location to dig."

If the location is chosen properly, the general will be rewarded. ”

Digging wells is also a science, people who are good at site selection can analyze the underground water veins according to the topography, and the site is located in the place where the water veins are abundant, and the wells dug out have enough water.

"The small family has been digging wells for generations and letting the little ones come." At this time, a clever little colonel raised his hand and sneered.

"Then don't you hurry?"

The little colonel took out a compass from his arms, looked around, and then stared at the compass with care, and said with words in his mouth: "Looking for the dragon and dividing the gold to see the winding mountain, a heavy entanglement is a heavy pass......"

"Wait!" Tao Qing said angrily: "Are you so sure that your family is digging wells? ”

"Yes...... Be...... This is a small family ancestral craft......" The little school turned pale with fright.

"Bastard, I think your family is an ancestral tomb robbery," Tao Qingqi was angry, the tomb is generally selected in a dry place, if you use the method of finding a tomb to dig a well, it is strange that you can dig water.

"Small home...... It is true that the gold will be divided, but the site will also be dug at the site. ”

"Okay, okay, I'll believe you once, I can't get the water and then settle accounts with you," Tao Qing waved his hand impatiently.

Even if he knew that this kid was a family of tomb robbers, after all, he was a soldier under him, and there was no need for him to deal with this chaos.

Besides, he had no other way than to believe in the heir of the tomb robber in front of him.

The little school was extremely efficient, and with the compass in hand, he instantly set seven or eight positions within a radius of more than ten miles.

Tao Qing gave an order, and all the soldiers picked up shovels and heads, and began to dig down at those positions at the same time.

After all, a well can't explain the problem, delineating such a large area, if these seven or eight wells are dug out of clean water, not brine, he can go back and report to Liu Ping.

He also felt that the analysis of the soldiers just now was correct, with Liu Ping's high status, how could he have come to such a desolate place? Even if you have been here, do you know if this is brine or not?

Sitting in the study, I randomly clicked a place on the map and told him that he could make brine and dry salt here, why does this sound so mysterious?

In order to get out of this ghost place as soon as possible, the soldiers dug very hard, and the depth went down at a speed visible to the naked eye.

Tao Qing, as the leader of this team, set up camp in the middle of those wells.

"General, out of the water!" With a shout, the first well was dug out of the water.

"How's that, how's it, what's the smell of water?" Tao Qing hurriedly ran over, lay at the mouth of the well, and looked down.

I saw that the well was about two or three zhang deep, and there were several soldiers at the bottom who were busy blocking the spring.

According to the practice of digging a well, when digging a spring, it should be plugged first, keep the well dry, and then continue to dig down until two or three springs are dug out, and then open the spring at the same time, so as to ensure that the water in the well is full of head.

It seems that the little tomb robber did not deceive people, the first spring dug here was full of water, and those soldiers were busy, and there were some postures that could not be stopped.

However, someone had already brought a bucket out of Tao Qing in advance.

Tao Qing's liver has been hot for the past two days, and he is really thirsty, so he took a handful of water with both hands and drank it fiercely.

"Poof—"

He just took it in his mouth, and before he could swallow it, he opened his mouth and squirted out, saying with a bitter face: "Why does this water taste like this?" ”

He chirped and licked the remnants of his mouth: "It's so salty, it's killing me." ”

"Could it be...... Is this really brine? ”

The soldiers looked at Tao Qing's embarrassed appearance, but they didn't dare to laugh, and gathered around to see the clear water in the bucket, which seemed to be no different from ordinary well water.

I dipped my finger in it, and when I put it in my mouth, it was really salty.

"I just don't know, can salt be dried out of this water?"

These people were born in Danyang, and Danyang County is not a salt-producing area, so no one has ever seen salt.

"Whether you can dry the salt or not, you can only try to know, but you have to wait for this bucket of water to dry, I'm afraid the time will not be short,"

Tao Qing looked at the big sun overhead, although the autumn tigers were raging, and the wind in this place was also very strong, but letting such a bucket of water dry naturally, it was not possible to complete it overnight.

"It's so small that I have an idea," a soldier next to him said: "The general just wants to try whether this bucket of water can dry out the salt, in fact, there is no need to dry it at all, the general pours the water into the iron pot, and a fire is built underneath, and it doesn't take an hour for the water to dry. ”

"You're so fucking smart," Tao Qing couldn't help but admire, and then commanded the soldiers to take two mouthfuls of the cooking stove, put it on it, pour the bucket of water into it, and light a fire underneath.

After a while, the water boiled.

Tao Qing looked at the boiling water, and his heart was also up and down.

Whether you can produce salt or not is all in this pot.

If the water in all the wells could not produce salt, he immediately led his army back to Chang'an.
