When they looked at him again, all the parts below the calf were sucked into the grass. Xia Xue rushed over with an arrow step, and shouted at them at the same time: "You are not allowed to move, lie down on the spot!" ”

Song Gang and Li Kang had no choice but to lie down on the grass.

"The rest of the people also don't move, and they all lie down!" Ouyang Qian and Jiang Yong were also all lying on the grass.

Xia Xue also quickly lay down, slowly crawled towards Song Gang and Li Kang, untied the rope from her waist as she climbed, she pulled the rope in a circle and threw it at Li Kang.

"Put the rope trap on yourself, then hold on to the rope and lie on your stomach and don't move." Xia Xue ordered.

Li Kang gripped the rope tightly with both hands, and the turf was already up to his knees.

Xia Xue also ordered Song Gang loudly: "Get down and climb out of this place." Song Gang originally wanted to drag Li Kang, but when he heard Xia Xue's order, he had to lie down and slowly climb back.

Ouyang Qian was anxious to step forward to save Li Kang, but Xia Xue yelled sternly: "No one is allowed to approach Li Kang, and no one is allowed to make senseless sacrifices!" ”

"Li Kang, I'll pull you slowly, you have to be careful when moving your body. With each movement, give the mud time to flow under the limbs. Don't rush, moving quickly will only create a gap between the mud or sand and suck your body into the depths. ”

Xia Xue pulled the rope hard while explaining the precautions to Li Kang. Half an hour later, Li Kang was finally dragged out of the grass and mud.

Looking at the turf that had just fallen into it, it quickly closed again, leaving no trace.

"Crawl slowly, don't stand up." Xia Xue ordered Li Kang.

Li Kang, who was a little frightened and demented, obediently followed Xia Xue's order and slowly came back.

Xia Xue then ordered all the personnel to slowly crawl and retreat to safety.

Everyone finally escaped, Li Kang was covered in mud, paralyzed on the ground and weak, almost sucked into the grass and buried alive, this terrible thing really frightened Li Kang.

"When the snow melts, this meadow turns into a dangerous swamp, and there are dangerous traps hidden everywhere, and the herd of antelopes just now was swallowed up by the swamp." Xia Xue explained to everyone the reason for the danger just now.

"Your Majesty, this meadow is very large, and it is difficult to get around, so how do we get through it?" Ouyang Qian asked anxiously.

"Standing on the turf, it's easy for people to sink in. And lying on the turf, but nothing happens, do you know what the reason is? ”

Everyone shook their heads.

Xia Xue stood up, took out the Tang knife and said, "The tip of this knife is easy to pierce a person's body, but it is difficult for a fist to penetrate a person's body." Because the pressure on the tip of the knife is strong, the pressure on the fist is small, and the pressure is inversely proportional to the force area......"

Everyone listened to it in a fog, and they couldn't understand Xia Xue's words.

"Your Majesty, is it difficult for us all to crawl over the grass? Then there are war horses, how can they climb over? Ouyang Qian asked as if she didn't understand.

"We can cut down trees and make planks or rafts, so that we and our horses can walk through the swampy meadows on planks or rafts."

"Your Majesty, these truths you are saying are too profound for me to understand. We can do an experiment, I go to the place where Li Kang has fallen, let the turf suck my feet in again, I take a plank and prop it on the board with both hands to see if I can pull myself out. If we can pull it out, we can bring a wooden plank when we encounter a swamp in the future. Song Gang said while comparing paintings.

"No, what if I can't pull it out?" Li Kang was worried about putting Song Gang in again.

"Last time, it happened so suddenly that everyone wasn't prepared. This time we can be ready for rescue......" Song Gang still insisted on his opinion.

"Song Gang's suggestion has a certain scientific truth, as long as we are prepared for rescue, it is estimated that there will be no danger to life." Xia Xue approved Song Gang's proposal.

"Your Majesty, I weigh less than Song Gang, let me do the test." Ouyang Qian squeezed over.

In the end, Xia Xue made a decision that Song Gang would do the experiment, but put a rope on her body in advance, just in case.

Song Gang hugged a wooden plank, ran to the place where Li Kang had fallen, and jumped the turf a few times, and the turf really sucked his feet in. He laid the plank in front of him, propped his arms on it, and pulled out his feet that had sunk into the turf. He let the turf suck his feet in, let the turf sink to his knees before taking measures to save himself, and still pulled himself out of the swamp by the plank.

"Immediately cut down the trees and make a plank for each of them that was more than three feet long and more than a foot wide, and had triangular ends at both ends. This one is for personal use, take it with you, and don't leave it in the swampy meadows. It is also necessary to make a batch of large planks or wooden rafts for the horses, and act quickly. Xia Xue gave an order to Li Kang, Song Gang and others.

After a day, the planks and rafts needed were basically made.

Xia Xue was still not at ease, so she popularized the knowledge of the swamp and the self-rescue method of the swamp in distress to Ouyang Qian, Li Kang, Jiang Yong and Song Gang.

"When passing through a swamp, you should have a probe staff in your hand and explore solid ground or shallow muddy water. There are often ponds formed by clumps of plants in the swamp, and these floating layers composed of broken leaves, lake grass, and soil have different thicknesses, strengths, and supporting forces, and it is easy to have accidents when walking on them. If you come across a place with bright greenery, you should detour because it is either humid or has a thin floating layer, and there is likely to be a mud pond underneath.

The quagmire is generally found in swampy or damp, soft and muddy wilderness areas. When you see a black flat ground with no grass, you should be even more careful. At the same time, keep an eye out for cyan sphagnum bogs. Sometimes, moss fills the surface of the bog like a carpet, which is the most dangerous trap.

In case of falling into a swamp, do not panic, put down the probe stick, throw off the backpack, lie flat, try to expand the contact surface between the body and the swamp, and control the speed of sinking. Once the sag is under control, you can use the roll of your body to get yourself out of the swamp. You can also use your body to lean forward to extend this distance. If you notice that your feet are sinking, you should lean back and fall gently. When falling, try to spread your arms as far as possible to spread your body weight, which will keep your body on the surface. or climbing or approaching dry ground or other attachments. For example, if there are tree roots and grass next to you, you can pull it to move your body. Caution must be exercised when moving the body. With each movement, you should give the mud time to flow under your limbs. Don't rush, moving quickly will only create a gap between the mud or sand and suck your body into the depths. It usually takes about an hour to move a few meters. If you feel tired, stretch out your limbs and lie still. This position will keep the body from sinking.

If you have a walking stick, you can stick it in the sand and mud under your body. If someone is traveling, lie still and wait for the companion to throw a rope or stick and drag him out of danger. Rapid movement is not only not very helpful, but it can quickly exhaust you. If you are alone, lie down facing the sky, gently flick your hands and feet, and slowly move to the hard ground in a backstroke position. ”

Xia Xue, Ouyang Qian, Li Kang, Jiang Yong, and Song Gang spread large wooden planks or rafts on the grass, so that the men and horses could safely pass through the death swamp.
