The farther north went, the temperature eased a little, Lu Yingfang asked the system, now the highest temperature during the day is 30, and there are fifteen or sixteen degrees at night. Although there is some cool autumn, there is less water along the way!

Their official roads are so far away from the water source that it takes more than an hour to fetch water and back and forth each time, sometimes longer.

It's a hassle to run out of water for two days in a row! People can endure it, but horses can't, and if they get sick, it's very troublesome.

It hadn't rained here for a long time, and the creek I had been there was about to dry up, and everyone was in a hurry. I don't know what the next road holds!

The soldiers who went to explore the road this time found that there was a big river not far away, and everyone was very happy, but when they got there, they found that the river was muddy with cement and sand, and there were foreign objects floating and worms and leech larvae, which made people's scalp tingle.

Zeng Mao heard the report from the soldiers, ran to the river to take a look, and his heart was cold. They hadn't found a water source for two days, and now they couldn't use it, so what if the next stream dried up again?

Lu Yingfang was also happy, but tonight there was finally water to wipe her body. When I heard that the river water could not be used, my heart suddenly cooled.

She remembered that she had watched a lot of wilderness survival programs before, and thought that there were several ways to get water in the wild, and she would see if she could use it. She insisted on going to the water source, and Qiu Da had to lead her on a long mountain road.

Zeng Mao was asking people to fetch water, and then boiled it on the spot with a small stove, trying to see if he could drink it.

Even the boiling water is very muddy, and a bunch of unidentified objects float on it, making it disgusting to look at, let alone drink.

The water could be given to the horses, but people could not drink it.

Zeng Mao saw Lu Yingfang take a look at the water in the pot, so he looked around. Finally, let a few descendants of the Lan family start digging a pit at a place by the river.

Zeng Mao walked over, and Lu Yingfang said that the water in the river could not be drunk, and tried to dig the pit again.

Zeng Mao waved his hand and beckoned the soldiers who came with him to dig a pit together, and dug a big pit according to the old lady's wishes. After a while, there was really water overflowing.

"There are no worms in this water." A soldier scooped up a scoop of water and exclaimed in surprise.

Lu Yingfang did not breathe a sigh of relief, she said to Zeng Mao: "The water of the river is full of insect eggs and dirt, and this water still needs to be filtered. "This is Qiu Da has made a simple filter, she asked Lin Zi to pour some yellow river water down, and the water flowing from the filter is clean.

Zeng Mao knew that everyone in the Lan family drank boiled water, and Mrs. Lan said that it was not easy to get upset. He also passed on the order to do it, but some people felt that boiling water was troublesome and did not drink boiled water, and he didn't bother to care about it one by one.

"How is this done?" Zeng Mao blurted out, with this, there is no need to worry about water sources when marching and fighting in the future.

Lu Yingfang nodded at Qiu Da, and Qiu Da spread out the things in his hand and explained them one by one: "If there is no oil paper outside, you can use large leaves to make a funnel and put a layer of cotton cloth, you see, this is clean fine sand, charcoal powder, fine sand, charcoal powder, fine sand, 5 to 7 layers, press tightly and press ......."

It's that simple? All the soldiers present opened their mouths wide so that they could get clean water?

Lu Yingfang was interested, and then said: "If it's inconvenient to be outside, take a pipe...... A pipe like a flute, a ball of grass, charcoal, and a layer of cloth can also directly absorb water from the river. "I learned this from watching Bei Ye's program on TV.

"If the water found is not clean, you can also collect it in a basin or pot or other water storage container, put a small amount of alum or mashed kapok branches and leaves, and then mash the cactus and walnut kernels, stir well, and settle for two quarters of an hour, and the water on the surface is also pure." As soon as Lu Yingfang finished speaking, she suddenly found Zeng Mao saluting her.

Zeng Mao: "Mrs. Xie instructed that in the future, the soldiers will be able to drink clean water." Although the other two methods mentioned by the old lady have not been tried, facts speak louder than words. Those things in Qiu Da's hands actually really cleaned the yellow river water.

Zeng Mao's personal soldier followed: "Old lady Xie pointed." ”

The rest of the soldiers were smart this time, and said in unison: "Old lady Xie pointed." ”

If the previous meal made the soldiers grateful, this drinking water problem really helped them solve a big problem. When they were on the march, it was a trivial matter to drink raw water and make trouble with their stomachs, and some even contracted dysentery and lost their lives.

Lu Yingfang was very surprised to see that the gratitude values given by the soldiers were all 2 or 3. They are not the Lan family, and they used to provide merit points like 0.1, but this time they actually have such a high merit value.

"It's all trivial, hello everyone, it's really good." Lu Yingfang smiled and hurriedly advised, "This raw water still has to be boiled, especially this water may still have a lot of insect eggs, boil it for a while before drinking." ”

In order to be safe, Lu Yingfang had to filter the water dug out of the pit and then boil it before drinking.

Because there were a lot of pits to be dug and the water was slow, it was delayed and it was dark.

Zeng Mao received a report from the soldiers that a lot of wild beast feces had been found nearby, and this was the water source, so I was afraid that it was dangerous.

There was a drought in the north, and I didn't know when there would be water on the way, and the soldiers sent out have not returned so far. So they have to replenish the water here.

After getting the water for tonight, Zeng Mao ordered to leave some soldiers to get water tomorrow morning, and borrow the Lan family's spare carriage to load the water.

The Lan family has eaten a lot of food, and the carriage has long been empty. Just enough to hold water.

Everyone withdrew from the mountain forest, and when they returned to the camp, they learned that a wolf pack had attacked the horseman on the Lan family's side. The coachman was bitten by a wolf on the leg and stomach, but fortunately, the people around him rushed to the rescue, and the soldiers next to him reacted quickly and opened their bows and arrows, which saved the people. The wolf left two carcasses.

A horse was bitten to the point of dying, and Lu Yingfang took the initiative to kill the horse and share meat for everyone to eat.

When Lu Yingfang learned that it was Xing Guan who saved the driver, her mood was a little delicate. Ever since Xing Guan ate Huoxiang Zhengqi Pills, he has been brushing his presence on the Lan family's side. Now that he has saved people, she has to thank him again. This came and went, and in the eyes of others, the friendship between the two of them seemed to come up.

And that's the last thing she wants.

Lu Yingfang was angry this time: System, are you dead? There is a wolf pack attack, why don't you warn of it?

- Beep, I'm sorry, I didn't pay attention to you filtering the dirty water in the field. Besides, the coachman was not dragged away by the wolves, he couldn't die if he was bitten!

For the system, probably not dying is a trifle!

I was bitten by a wolf, and there is no vaccination to get it! If you have a virus like rabies, you can't do anything! Lu Yingfang calmed down, maybe she relied too much on this system, it seems that this system can only be used as Taobao.

- Don't be angry! In fact, this system is just here to urge you to earn merit points.,I really don't know about the other directions of the plot! It takes a lot of energy to keep an eye on everyone's movements.

Lv Yingfang: If there are earthquakes, mountain floods, locust plagues, etc., can you still warn of them?

- It can be, but it may not be timely enough!

In other words, although the system promised to warn, it was not very reliable!

Forget it, it's her who thinks too much! The so-called golden finger is a vague plot, plus a system that only needs "merit points".

She went to see the driver herself, a man about twenty or thirty years old, who was the man of the car dealership.

- This driver has always contributed merit! You advanced half of the money to the coachmen, relieved his urgent need, and gave his father money to see a doctor. So he was grateful that you had tried to improve everyone's food level along the way, and he also contributed merit points.

Lu Yingfang asked with concern, so that his merit value contributed another 0.2. The other party is gracious, Lu Yingfang moved her mind, maybe there will be a small stronghold in the capital in the future, maybe this coachman can do it.

Lu Yingfang promised to give him another ten taels of silver to recuperate. However, the driver said that he asked her to keep it for the time being. He was afraid that if he came all the way, he would lose it, or if it was stolen, he would be in trouble. After Lu Yingfang agreed, she turned around and asked Qiu Da to observe whether the coachman was available, and then asked Aunt Gu to boil medicine for him, and then she returned to the carriage.

Just now she had heard Zeng Mao's explanation to the soldiers, the wolves could have attacked at night, but now that so many people are active, they are all attacking. There are two reasons, one is that there are many wolves and they are courageous. Instead, the wolves were hungry and chose to attack immediately. Whatever the reason, it's not good for their group.

Lu Yingfang searched and found out the "Wild Trap Making Method" and bought it directly.

She knew that this group of soldiers had been on the battlefield and had many archers, but their ranks were too long, and the archers couldn't take care of so many people.

Lu Yingfang lit an oil lamp in the carriage and quickly traced the picture on the electronic screen. Fortunately, these drawings are not difficult, and with the text description, you can understand them.

The drawn several trap diagrams were quickly brought to Zeng Mao by Qiu Da.

Soon, the camp was lively.

The wolves will definitely attack tonight, and if there are no archers, try to set traps. Fortunately, this is a mountain forest, so there is no need to worry about accidentally injuring people.

This time the trap was with a bow and arrows, and the bow was not enough, but fortunately there were a lot of arrows. The soldiers made a simple bow out of appropriate marblewood, resting it on a forked stake fixed to the ground, the arrow arched over a taut string, and the toggle rod attached to the tripwire was attached to the upper end and stuck to the trigger stick on the downward groove on the side of the arrow, so that the open bow and arrow were balanced. Use three short stakes that are far apart and fixed to the ground to change the direction of the triprope, and the prey touches the triprope in exactly the direction pointed by the arrow.

If you touch the rope, you will be easily hit by an arrow if you are a large beast or an animal approaching from the side of the triprope, so you don't have to worry about a night attack. I'm afraid that there are too many wolves, and some wolves that have slipped through the net will come forward and bite people.

In addition, there are traps such as ropes that are used one by one.

That night, the wolf howl in the forest kept ringing, disturbing everyone from sleeping.
