After the separation, the family had a lot of fish and meat every day, and the best was furious

Xiao Jingchuan had thought of all the methods and asked the soldiers to think of them with him, but no method was feasible.

If Lin Ting can solve the problem of drinking water for the army and the people in the border town, he can only do so by bringing the Rain God.

"Yesterday, Yi'an brought people to Weirui Pavilion and took all the water from my well. This gave me an idea that might solve the problem of drinking water in Border Town."

"You want us to dig a well?"

Xiao Jingchuan heard what Lin Ting meant and immediately came to a conclusion.

Xiao Jingchuan and his men had tried digging wells a long time ago. The well in Weirui Pavilion was deeper than all the wells in the border town.

If water could be obtained simply by digging wells, the army in the border town would have plenty of people. However, after digging the wells, a large amount of water would have to be injected into them to bring up the groundwater.

But where can they find plenty of water now? They don’t have the ability like Lin Ting to spend money to dig a well.

"No, digging a well is not the best option. I have been observing the water output of the well in Weirui Pavilion since daytime yesterday.

There is a big difference between the water output during the day and at night. Based on my observations and calculations, I think there should be an underground river in the border town.

As long as we can find this underground river and dig it out at its shallowest point, the problem of drinking water for the army and people in the city over there will be solved."

Underground river?

Xiao Jingchuan seemed to have seen this unfamiliar word in a book before, but the book used exaggerated words to describe things, so he thought it was a word imagined by the author.

"An underground river? It's underground, underneath the ground we're standing on?"

Xiao Jingchuan confirmed with Lin Ting again, wondering if it was what he understood.

"Yes, it's right under the land we are standing on. As long as we determine the location, we can start digging."

Xiao Jingchuan felt that what Lin Ting said was a fantasy. Even if there really was a secret river as she said, how could they determine the location?

Could it be possible that such a huge border town would be turned upside down by digging deep into the ground?

"Madam Lin, are you kidding me? I understand what you said, but I don't quite understand it."

General Han had the same doubts in his mind as Xiao Jingchuan. Lin Ting was very smart, and what she said was generally of reference value.

But even if we are sure that there is such a river, it is difficult to find it.

"General Han, Second Prince, since you can guess that there is an underground river, it won't be difficult to find it."

As Lin Ting spoke, she stretched out her hand, and Bai Lu handed the mugwort in her hand to her. The border town was dry, and there was nothing else, but mugwort was everywhere.

The one in Bai Lu's hand was picked by her at the entrance of the military camp.

"The grass in my hand is called mugwort, which is also a Chinese herbal medicine. It is usually used for moxibustion and has the effect of dispelling cold.

In traditional Chinese medicine, each herb has its own properties. When you apply moxibustion on your body, you see the smoke going up, but its properties are sinking downwards.

It will find the place in the body where the cold is the heaviest and dispel the cold. The formation of cold originates from water.

As long as we gather this mugwort and burn it in one place, its medicinal properties will move downwards. If it comes into contact with water, you will see white smoke rising from the ground."

After Lin Ting finished his proposal, Wan Weiran immediately applauded.

"Yes, why didn't I think of this method? The human body and nature have many similarities. If there really is an underground river, burning wormwood is the fastest way to find it.

Master Lin, Master Lin, you always come up with such wonderful ideas. I look at the wormwood all over the ground outside every day, but I still can't think of any."

Lin Ting and Wan Weiran agreed with each other. Xiao Jingchuan didn't understand pharmacology, but since both of them thought so at the same time, it meant that this method was feasible.

"Without further delay, I'll find someone to do it."

Xiao Jingchuan immediately stood up and went outside the tent, calling Yijia to assemble the troops.

Yijia received the order and shouted to the people outside the military camp.

"Come on, gather..."

Soon, a team of two hundred people was assembled in the army, and Xiao Jingchuan stood in front of the army and gave orders.

"Do you see the grass in my hand? Go outside and cut some of it. The more yellow grass, the better. Collect all of it and bring it to me within half an hour."

"Yes!"

More than two hundred people spoke in unison. They were soldiers, and the first military order of a soldier was to obey his superiors unconditionally.

Xiao Jingchuan took Lin Ting to find a good place to burn mugwort.

After calculating the area of ​​the border town, the two men finally decided to go out of the city gate and burn outside the city.

Xiao Jingchuan gave the order and Yijia was responsible for the execution, and soon the mugwort was piled into a small hill.

The men under him set fire and burned.

The weather was already dry, and all they picked up were dry mugwort. When they burned it, it quickly turned into a raging fire, and thick smoke rushed into the sky.

"Madam Weirui, what now? What do you want us to do now?"

Xiao Jingchuan always listened to Lin Ting. Yijia didn't ask him this time, but asked Lin Ting directly.

"Now, gather some people and search within a 20-mile radius, with this wormwood fire as the center. If you see smoke coming out of the ground, mark it immediately and report back."

"Yes!"

Yijia went to make arrangements, this time calling in more soldiers and doing things according to Lin Ting's method.

Xiao Jingchuan and Lin Ting stood by, looking at the pile of flames that was as big as a small hill. With the naked eye, the smoke was rising. He didn't know whether things would really be as Lin Ting said?

Anyway, since Lin Ting gave him a solution, he believed it. Even though he had doubts in his heart, he was still willing to listen to Lin Ting and give it a try.

"It will take a while for the wormwood to burn out. Second Prince, why don't you go back and rest for a while?"

This method of using mugwort to find water will not be quick. It may take an hour or two, or in the afternoon, or even tomorrow.

However, Lin Ting was confident in her knowledge. She deduced that there must be an underground river.

"This is about the drinking water problem in the border town. I have to watch from here."

Seeing that his persuasion was futile, Lin Ting walked over to a tree and sat down. Bai Lu gave the water bag on her body to Lin Ting to drink.

After all the mugwort was burned, Yijia asked a group of people to look for it because he trusted Lin Ting very much.

A woman can make her career so powerful. Just by spreading rumors about Saren, she can help the border town army win with fewer troops.

This kind of woman is exactly the kind of person he admires the most. She is too smart and feels that there is nothing in this world that she doesn't know.

At noon, Lin Ting ate corn porridge with the people in the military camp. The corn was all fresh corn sent from the court.

The emperor also gave food to the people in the border towns. Although it was not much, it would not let the people starve to death.

At the end of the day, the pile of mugwort turned into ashes. In the evening, when it was almost dark, Yijia's men finally brought good news.

"Report, Commander, Master General, white smoke is coming out from under the cracks in the rocks two kilometers outside the city."
