Open one and take a look. From the ancient times when humankind began to reproduce, it starts to introduce in a dull and tasteless way, but is extremely academic! If they hadn't all been to college, they would have had no patience to read through!
After reading a big circle, several female students summarized a few points. To give birth to a healthy child smoothly, in addition to paying attention to diet and mood, appropriate exercise is also necessary.
In ancient times, women who often farmed were more likely to give birth to children. Some even worked while giving birth and then continued working after resting for a few days in order to make a living. They didn't even do a full month's confinement.
However, the chances of difficult labor were extremely high for young ladies who never left their rooms.
In terms of nutrition, carbohydrates and protein are needed. Folic acid, fish oil, DHA and other nutrients also need to be supplemented.
It sounds quite sophisticated, but on the island, these are not so hard to obtain.
For example, the more common tuna, salmon, mackerel, yellow croaker and most deep sea fish contain large amounts of fish oil and DHA.
Folic acid is even easier. Animal livers, bamboo shoots, and all kinds of fruits.
Moreover, even without pregnant women, these things can greatly improve people's physique and quality of life.
The girls pored over it for a long time, quickly jotting down all the useful knowledge points they came across.
Of course, they also saw some strange knowledge points.
Ning Shu said, "It's a rumor that girls can get pregnant by sleeping with a boy's used bedding!"
Lin Qianqian said, "Swimming together won't result in pregnancy either!"
Jiang Yao said, "But don't believe that just rubbing without penetration is safe. There are case studies on this!"
Tang Xiaoguo reminded, "Did you hear that, Lu Zhe!"
"Why are you telling me this? Give me the phone quickly. It's going to run out of battery soon."
Lu Zhe took it and started browsing.
While all the girls were enthusiastically looking up how to nurture the fetus, he was more sensible and looking up some pre-pregnancy information.
He calculated the days. Shen Bing was already nearly a week late. But isn't this abnormal?
For someone who has always been regular for over ten years, it is indeed a bit abnormal.
But is their current environment normal?
Next, Lu Zhe noticed this:
"Central inhibiters and hormone drugs can cause intense sexual arousal in females. The brain stays in a state of high excitement and tension for a long time, which severely affects estrogen secretion and causes menstrual delay.
In addition, malnutrition can also cause delayed menstruation!"
Lu Zhe immediately thought of the psilocybin mushrooms and bamboo shoots they had eaten. Those are psychedelic drugs with strong stimulation.
That is to say, Shen Bing met the necessary conditions for menstrual delay.
Then what about the bodily changes she mentioned?
Nausea? That would only happen after one or two months!
In this case, the stimulating taste of bear meat could also cause nausea. Even I feel like throwing up when I suddenly eat it.
Drowsiness? Who wouldn't want to sleep more after so much activity every day.
Look, when there's nothing to do in the cave, you don't feel like sleeping, do you?
Could it be that you got it wrong, Sis Shen?
At this point, Lu Zhe was also unsure.
But now, without the means to accurately test the high and low levels of chorionic gonadotropin, there was no way to accurately detect pregnancy.
The only reliable way was to wait for the next menstruation.
Better nurture the body and observe for a period of time before jumping to conclusions.
After Lu Zhe finished checking, there was only 4% battery left on the phone.
"Lu Zhe, anything else you need to check?"
"Nothing for now."
Jiang Yao said, "Let's look through the photos. No problem with that, right?"
Lu Zhe felt looking at old pictures would comfort everyone's mood after being stranded on a deserted island for so long. "Go ahead."
Shen Bing was very eager. "Can I see too?"
"Come, come, everyone come!"
Ning Shu opened the photo album. There were over a thousand photos, including recent ones as well as old ones saved from the cloud storage of the previous phone.
These were all the bits and pieces of their college days.
"Look, this was the inter-university football league. Number 7 is Lu Zhe, our business school's only male representative for our university!"
"Lu Zhe is so amazing!"
Lu Zhe nodded. "I'm alright."
"The one holding the sign is our etiquette class monitor, Lin Qianqian!"
Shen Bing scrutinized Qianqian carefully... "Wow, Qianqian is so beautiful!"
Qianqian blushed. "No way?"
"Back then so many boys chased after Qianqian! Even more than those chasing me!"
"Look, we all got selected for the cheerleading team..."
...
After looking for a while, there was 2% battery left. Ning Shu decided to switch it off to avoid draining the battery each time, which would damage it too much!
Looking at the old photos, hope and feeling were evoked in each friend's eyes.
"Since we can see the photos now, I believe our days ahead will get better and better too!"
Right then, the sound of rain outside seemed much lighter, not as deafening as before.
Jiang Yao said, "Let's all have a good sleep and sweet dreams. I'll keep watch next."
"Thanks Yao Yao!"
Lu Zhe lay down horizontally on the bear fur and quickly fell asleep.
When he woke up again, it was already 10am.
The night watch had been taken over by the monitor Qianqian and Yao Yao. Shen Bing was also up. The three girls were using the last of the python meat and vegetables to cook soup.
"Have some to warm your stomach."
Lu Zhe nodded. Hearing the lighter rain outside, he asked: "Did the rain get lighter again?"
"What lighter rain? When I took over from Yao Yao, it was pouring even harder than at the start, been madly pouring for a few hours already. It only started slowing down recently."
Lu Zhe nodded. Thankfully this bear cave was elevated several meters above the ground, otherwise they would have been completely flooded.
Pushing the bamboo door open to take a look outside, it was still pitch black.
Lu Zhe was shocked. He looked at his watch again. "I'm not wrong, right? It should be 10am now!"
Ning Shu nodded. "That's right!"
When she looked outside, she became doubtful. "I can't be sure now either. Isn't it 10pm at night?"
"Should be daytime."
After comparing Tang Xiaoguo and Lu Zhe's watches, they displayed the same time - 10 o'clock.
Shen Bing worried. "Could it be reversal of night and day? Or is it that the cloud layer has been blocking sunlight all along?"
"The first is too fantastical. The second has higher possibility."
Lu Zhe continued thinking. "If it's the clouds, then this rain may really last a long time!"
Ning Shu said, "Ah? I thought it was almost over!"
"This is like the extra time in a ball game. Regrettably, we don't know how long this game will last, nor how many times such extra time will happen."
Lin Qianqian said, "Fortunately, we feel very cozy here, no need to worry about wind or rain."
Lu Zhe pondered: "I need to head out while the rain is lighter!"
Shen Bing was surprised. "What?"
"Judging from the cloud density, the rain may keep falling for a long time. It's uncertain when there will be light rain again. I need to gather some more food supplies and firewood to store up."
Shen Bing objected. "It's too dangerous to go out now."
Lu Zhe understood Shen Bing was right. Exploring the jungle in the rain was extraordinarily risky, but what choice was there?
"If I don't go out now, when we run out of supplies, we'll either starve or still have to go out in heavy rain to find stuff."
