Sea cucumber has a great tonic effect, and is generally used by people who are weak or elderly to replenish their bodies.

Chen Zhe is in the prime of life, he is a young man with strong blood, and eating sea cucumbers at his age is almost equivalent to adding fuel to the fire.

Chen Zhe, who woke up, only felt that his whole body was hot and unbearable, as if he had swallowed a stove and went in, and he felt that he was afraid that something would happen if he hugged Yan'er again, so he struggled to get up.

Unexpectedly, when he tossed like this, Yan'er was woken up by him instead.

"Hmm...... I accidentally fell asleep. ”

The little girl rubbed her sleepy eyes and whispered.

"Yan'er, are you awake?"

Chen Zhe asked apologetically.

After all, he woke Yan'er up.

Yan'er nodded and sat up, looked at the moon in the sky, and then looked at Chen Zhe, then suddenly stunned, pointed to Chen Zhe's nose and said, "Xiao Chen, Brother Xiao Chen...... Why do you have a nosebleed?"

"Huh?"

Chen Zhe hurriedly wiped his nose, only to find that he had a nosebleed.

Bright red blood flowed out, staining his fingers red.

"Oh...... It should be that the sea cucumber has eaten too much and is on fire......" Chen Zhe said helplessly, "This thing is too supplemental, give me a lot of supplements." ”

"What should I do then?" Yan'er asked worriedly while leaning over to help Chen Zhe wipe his blood, "What can I do to extinguish the fire?"

"Forehead ......"

Chen Zhe thought a little embarrassed, he did know some methods to extinguish the fire.

After pondering for a while, Chen Zhe thought of a method: "I know, doing exercise can extinguish the fire." ”

"Do sports, do you do sports, do you need my help?" asked Yan'er innocently.

Chen Zhe smiled: "It's not necessary, I'll do it myself." ”

After speaking, Chen Zhe got up and picked up the blood-drinking knife and walked to the beach not far away.

He urgently needs to vent all the power of the desolation in his body now, so that he can consume the firepower brought by eating sea cucumbers.

Yan'er didn't know what Chen Zhe was doing, she was a little uneasy, so she got up from the blanket and followed Chen Zhe to the beach.

After walking to the beach, Chen Zhe waved the blood-drinking knife to dig a sand pit on the ground, the soil of the beach is relatively soft, and it is relatively labor-saving to plan, and in a blink of an eye, he has already dug out a very deep sand pit.

Yan'er watched from the side in a daze, and quietly pondered in her heart-

"Why did Brother Xiao Chen suddenly dig a sand pit on the beach like a child? Could it be that he is still childlike?

Or do you want to use this way to extinguish the fire?"

Just when Yan'er couldn't figure out the situation, Chen Zhe had already completed the first sand pit, which was about one meter in diameter and one meter deep, and it looked like it was in order, not like it was dug out for fun.

After digging the first bunker, Chen Zhe immediately started digging the second bunker next to him.

At this time, Yan'er couldn't help it, and asked curiously: "Brother Xiao Chen, do you have any purpose for digging these sand pits?"

Chen Zhe nodded and explained, "Yes, these sand pits are useful, they are simple salt wells for me to make salt." ”

"Salt well?" Yan'er's eyes flashed with a strong desire for knowledge, and she asked again, "Do you want to use these sand pits to make salt?"

"Hmm......" Chen Zhe replied and continued, "There is salt in the seawater, and we have to refine this salt from the seawater, and if we want to refine it, we have to find a container that holds the seawater, right?"

"Yes......," Yan'er said, then turned back and pointed to the wooden barrel in the distant camp, "but I thought the wooden barrel was a container for seawater." ”

Chen Zhe couldn't help laughing when he heard this, shook his head and said: "Silly girl, how big is the wooden barrel? How much seawater can it hold? The salt content in seawater is about 3.5%, which means that only 3.5 grams of solid salt can be refined from a hundred grams of seawater, you can calculate by yourself how much seawater we have to consume to make enough salt to marinate those wolf meats?"

"This ......" Yan'er counted with her fingers, and gave up directly in the end.

"It takes a lot of seawater!" she said in a high-level manner.

Chen Zhe smiled and admitted: "Yes, to practice so much salt, you need a lot of seawater, and the wooden barrel is definitely not enough, so I have to dig a sand pit." ”

Only then did Yan'er understand: "Dig a sand pit, use the sand pit to hold seawater, and then practice salt directly from here, right?"

"Yes. Chen Zhe said, and then said, "In addition, you see, there is no high tide yet, and the sea water has not yet passed here, and when the high tide comes in the middle of the night, the sea water will naturally cover these bunkers and fill the bunkers with seawater." When the tide recedes tomorrow, the bunker will be full of seawater, which saves us the trouble of fetching water ourselves. ”

Hearing this, Yan'er almost applauded Chen Zhe's wit.

"Brother Xiao Chen, you're too smart, aren't you? I said why you are digging a sand pit here, it turns out that you want to use the principle of tides to irrigate seawater. ”

Chen Zhe said with a smile: "Don't tout me anymore, I'm easy to be proud of you like this." ”

Yan'er smiled and said, "What are you afraid of? My little brother Chen is excellent, don't you let people say it?"

After speaking, the little girl also squatted down and followed Chen Zhe to dig a sand pit with a hard shell, and said while digging: "I also eat too many sea cucumbers, and I also need to extinguish the fire." ”

Chen Zhe knew that Yan'er was worried that he would be tired alone, so he took the initiative to help this time, so he handed Yan'er the blood-drinking knife, and he used shells to dig sand.

The two worked together and soon dug a neat row of bunkers out of the beach.

After another hour or so, the sea water gradually overflowed, Chen Zhe saw that the high tide was coming, and hurriedly took Yan'er's hand and said, "Okay, we have to go back quickly, the tide has already started, and it is more dangerous on the beach at this time." ”

When he first arrived, Chen Zhe didn't know much about the situation in this area, and if the waves of the high tide on the beach were more urgent, it was very likely to sweep people into the sea.

So be sure to leave the beach at high tide to ensure safety.

The two retreated hand in hand to the camp and sat by the campfire to watch the tide rise.

The surging tide came in waves, and the scene looked spectacular.

In the middle of the night, there were already many stars in the distant night sky, and when I looked up, the sky was full of stars and shining brightly.

The seaside is different from Chen Zhe's camp, there are no tall trees here, so it is easy to see the whole sky, looking up at the starry sky, Chen Zhe and Yan'er are shocked by the beauty of nature.

"Brother Xiao Chen, the starry sky is so beautiful...... When I was in the city, I didn't have a chance to see such a beautiful starry sky, and the stars were either obscured by tall buildings or blocked by smog. Yan'er whispered.

"Yes, so this wilderness survival is also a good opportunity to get in touch with nature, and many magnificent sights can only be enjoyed in the wild. Chen Zhe said softly.
