Everybody sleep, I'll keep Vigil.

Ning Shu nodded: "I see, but why not put them in plastic bottles?"

Lin Qianqian said: "Wouldn't the stones burn through the bottles!"

Lu Zhe nodded and said: "We use this method to heat the seawater to sixty or seventy degrees, then pour it into plastic bottles so it won't burn through the bottles! And once poured into the bottles, we will have free hot water bottles!"

"We have twenty bottles, which is equivalent to having 20 hot water bottles! These 20 hot water bottles should be enough to help us get through the cold nights!" Lin Qianqian suddenly realized: "What a great idea!"

Jiang Yao also praised: "Simple, direct, effective, and most importantly easy to operate!"

Ning Shu gave a thumbs up: "Lu Zhe, you really have a knack for this!"

Tang Xiaoguo also admired: "Why didn't I think of that?"

With the plan formulated, they proceeded to implement it!

The beach sand was fine and soft, easy to dig up. Lu Zhe and Ning Shu were responsible for digging the pit, Tang Xiaoguo collected stones, and Lin Qianqian was responsible for putting the stones in the fire to heat up!

Jiang Yao was responsible for fetching seawater, then using sticks to clip the heated stones and put them into cans!

"Hiss..."

As soon as the heated rocks were put into the cans, the seawater made a scalding sound, but after shaking, it quickly blended with the seawater into sixty to seventy degree hot water!

Although still a little hot to hold, pouring it into the bottles would not burn through them.

In just half an hour, Jiang Yao had made more than ten hot water bottles!

To keep warm, they were buried in the sand.

At the same time, Lu Zhe and Ning Shu used sticks to dig out a 2-meter by 2-meter square pit in the sand!

Dried by the fire!

Then the broad leaves were inserted obliquely around to cover the entire pit!

The hot water bottles in the sandy pit gave off waves of heat, just like a heater, dispelling the severe cold in the middle of the night!

Lying in the sandy pit, Tang Xiaoguo happily said: "Wow, warm and happy!"

Jiang Yao also lay down and fantasized: "It feels like...sleeping in a grave! Do you think a native will jump out in the middle of the night and bury us all!"

Upon hearing the words "bury", Tang Xiaoguo screamed in fright: "Ahhh..."

Ning Shu also shuddered: "Yao Yao, couldn't you refrain from telling horror stories in the middle of the night!"

Jiang Yao stuck out her tongue: "How thrilling!"

Tang Xiaoguo yelled: "What's so thrilling, I was so scared I peed..."

At this time, Ning Shu discovered a new problem: "A 2-meter wide pit can barely fit four people, if Lu Zhe squeezes in it definitely won't fit!"

Lin Qianqian blushed and said, "Besides, we're all girls here, it’s fine for us to sleep together, but it would be a bit awkward for a boy to be here!"

Lying at the edge, Jiang Yao pushed aside the broad leaves and slid over a bit: "Little Zhe, just sleep next to me!"

Tang Xiaoguo felt a little uncomfortable being squeezed by Jiang Yao: "Yao Yao don't crowd me!"

Jiang Yao dismissively said: "I just feel bad for my buddy and want him to fit, can't you make some room!"

Tang Xiaoguo angrily said: "You're so caring huh!"

Jiang Yao laughed: “Of course, not like you who just gives Little Zhe a hard time...”

"Yao Yao you... Hey, Lu Zhe why didn't you guys dig a bigger pit!"

"Because we don't need to!" Lu Zhe flatly said.

"Why not?"

"Because tonight, not all five of us can sleep, someone has to keep watch!"

Upon hearing the words "keep watch", the four girls simultaneously cried out: "Ah?"

"We still need to keep watch!"

"I'm tired to death, who can still keep watch..."

"I’m so sleepy, I just want to sleep until mountains crumble and earth and heaven unite..."

Only Ning Shu solemnly said: "Do we really need to keep watch?"

Lu Zhe nodded: "This is our first night stranded on the deserted island. In case something unexpected happens at night, we need to respond in a timely manner! We also need to tend the bonfire, add firewood, and change the hot water bottles for our companions!

So someone must keep watch!"

"But everyone is so tired..."

"Either draw lots or take turns standing watch. If no one is willing, then I’ll keep watch!"

Ning Shu thought for a moment, and very responsibly said: “Lu Zhe... you were the most exhausted today. How could we let you stand watch! If someone really must keep watch, then as class leader I’ll do it!”

Ning Shu's sense of responsibility moved everyone.

Lin Qianqian thought about it and said, "Class leader, you are tired too. I’ve been awake for a while without doing anything, so let me keep watch!"

Tang Xiaoguo was also moved, saying: “Actually, I'm not that tired, I can totally keep watch. Let Tang do it tonight!”

Seeing this, Jiang Yao also said: “Everyone stop competing. I woke up the latest and did the least work. If someone needs to keep watch, it should be me!”

Lu Zhe realized that although these girls were usually chattering noisily, when push came to shove they were very sensible and understood propriety!

And he himself, empowered by the system, had physique and stamina far surpassing his original self...

Since this was the case, he shouldn’t let the girls stand watch either!

Thinking of this, Lu Zhe stretched lazily: “I suddenly thought, if a prehistoric python or Godzilla crawled out at midnight, you wouldn’t know how to respond. So the first night I’ll stand watch myself!”

Tang Xiaoguo pouted: “There you go trying to scare people again!”

Jiang Yao worriedly said: “You can’t go a whole night without sleep!”

Lin Qianqian was also concerned: “It would be bad for your health.”

Lu Zhe smiled: “I’ll catch up on sleep when the sun rises. Then you can take over from me!”

Ning Shu thought about it: “No need to wait that long. I’ll relieve you after four hours. Everyone else just sleep soundly!”

Lu Zhe thought this was also feasible:

“Alright! Get to sleep early everyone, and rest up to meet tomorrow’s challenges!”

“Then... thanks for the hard work, class leader and committee member!”

“Well then...sleep!”

“Good night!”

“Qianqian, you're hugging me too tight!”

"Sorry..."

The four girls snuggled up together and soon began to sweetly snore!

They were exhausted!

So tired that as soon as they laid down, they fell asleep.

Lu Zhe sat by the fire roasting his hands, looking at the four exquisite beauties before him, and felt a strong sense of duty to protect them!

Add some more firewood first!

Lu Zhe broke some sticks into pieces and threw them into the fire.

Then he took a hot sand bottle and put it inside his clothes, warming his chest.

But it was destined to be a long hard night!

Might as well take this chance to open up the system and review the system data!

Current data!

Although body temperature, fluid levels, salt levels, protein, fat, carbohydrates were not very high, they were all above the safety line!
