Shen Feng didn't know so many things, in her opinion, she just took advantage of the kindness of a young man.

She didn't know what Shen Qingqing was paving for her behind her back, nor did she know Zong Wende's series of ideas.

She has lived with Shen Qingqing in a small county under the attachment of X City since she was a child, and she has become accustomed to the guidance and malice of others.

She has always played her role well, first because of the hope of the main personality, and later for the sake of the woman.

Thinking of this, Shen Feng remembered Shen Qingqing's actions before his death, and his eyes were dim.

It is also because of that woman's deathbed behavior that she will firmly believe in the existence of the master's personality.

However, no matter what she thinks of her now, Shen Qingqing has been dead for five years.

The Si people have become loess, and the past should go away with the wind.

The most important thing to focus on now is what is in front of you.

Shen Feng adjusted his mood, comforted a few words of the main personality that was bubbling because of her depression, and then focused on the present.

Without knowing what the future would be, Shen Feng directly prepared for the worst.

The question, however, is whether she should use the money left by her birth mother, or how much.

If things go as she expected, then the money will be a pile of waste paper; But what if the nations were strong enough to support humanity through the prophesied catastrophe?

Then her decision at this time will limit her future start, although it is not a failure, but it will also add a lot of trouble, and maybe it will affect her original intention, so that she has to compromise some things she does not want to do.

This is not what Shen Feng is happy to see.

Although Shen Feng has always believed in his own judgment, any guess is variable, as long as it is not 100% certain.

Turning the tables against the wind falls short and often changes in an instant.

However, from another point of view, the choice between the two is that one risk is to work hard or rely on the adoptive mother, and the other is to starve to death, freeze to death, thirst and bleed to death.

It's clear which is more important.

So Shen Feng took out his mobile phone and swiped it to buy it.

Not to mention, it was also the first time for her to try sorting goods from high to low prices, and it felt amazing!

No wonder everyone wants to make a fortune (cough

In addition to the sleeping bag she bought first, Shen Feng also bought high-power camping solar charging panels.

Although the unit price is not as good as a sleeping bag, Shen Feng can't stand it and buys 10 of them.

- The despair of running out of power is like the enemy pushing the tower and your phone flashes back, and your heart is flustered and helpless.

However, there are also expensive benefits, such as the charging pad can be folded and converted - easy to carry; Tiled together, the thickness is about eight centimeters - space-saving; Waterproof and dustproof, cold and heat resistant - do not pick the environment; It can be used between minus sixty (1) degrees Celsius and seventy degrees Celsius – just for survivalists.

Because there are many and important live equipment needed in Shenfeng's plan, although things like camp lanterns and other things come with solar charging, what if it rains for many days?

It's better to be prepared to feel at ease.

In addition, considering the rain, Shen Feng also bought five additional hand-cranked generator outdoor mobile power supplies, but this thing is too fragile, the only thing worthy of praise is that the equipment is small (16*8*24cm), counting the space of the internal line, the actual area in the space props is not large.

These charging equipment are mainly used to supply energy for another batch of materials, such as a series of equipment used to combat low temperatures, such as car electric blankets and heating belts, plus the daily electric pump outdoor water purifier no matter how low the energy consumption is, it also needs electricity.

In order to live a good life, Shen Feng also tried his best today!

Look back at the discussion group in the study hall.

All six of them were holding their phones, each assigned an item that needed to be compared and had an occasional conversation.

Now that most of the items have been discussed, we are left with the most difficult drugs to choose and buy.

"Now that eating, drinking, housing, and transportation have been discussed." Yang She said, "Let's take a look at the next item first." ”

[Medication].

He wrote on the blackboard.

Medicine is one of the necessary supplies, especially when you can't even find a doctor in the last days.

Of course, even if you find a doctor and run out of medicine, it is difficult for a clever woman to cook without rice.

"Directly related to life, antibiotics and anti-inflammatories."

Shen Feng didn't take his eyes off the phone, and said, "Especially for the treatment of skin infections." ”

Antibiotics and anti-inflammatory drugs are rarely used, but not in the last days, anti-infective drugs are essential for survival in the wild. Otherwise, the wound may become infected and ulcerated at any time due to soaking in the river water, and in severe cases, amputation and death.

"Painkillers." Yang She said jokingly.

In his view, pain is sometimes the murderer who destroys people's will to live.

"Antidiarrheal medicine!"

All:???

Chen Sisi found that no one was speaking, and when she looked up, she saw that everyone was looking at her with strange eyes, and hurriedly explained, "Don't look at me, what if you eat bad things, diarrhea and dehydration?" My grandfather said that when they were marching, many comrades died of dehydration because they drank unclean water! ”

Chen Sisi looked embarrassed and hurriedly raised his arguments.

- This girl......

Shen Feng felt quite appreciative, she found that Chen Sisi's thoughts and remarks were sometimes very good, just like the previous military rations, which was also the address of the online store that she said and provided.

Chen Huimin saw that the little sister was fried, and hurriedly smiled and comforted, and wrote down the antidiarrheal medicine on paper.

While she didn't think she would eat anything else, especially if there was plenty of food and water in the space, she could prepare one if there was enough space.

She didn't know that the anti-diarrheal medicine she had prepared that she didn't think she needed at all saved her life when the city disappeared in the future, the planet was formatted, and she almost died of dehydration when she had to eat weeds with other people to hide the existence of space props.

At this time, like Tian Mengdan and Hu Yunpeng, she didn't pay attention to it.

Shen Feng and Yang Shezhi are different from those three, one of them places orders directly at the online pharmacy, and the other is editing information to distant relatives.

Shen Feng was very happy, because she had omitted antidiarrheal drugs in her original plan, but through Chen Sisi's mouth, antidiarrheal drugs were one of the necessary medicines.

Not bad.

Sure enough, we can discuss together to find out and fill in the gaps.

"Alcohol." Yang She saw that everyone didn't speak, and thought about it again.

"And I recommend 95 percent alcohol."

"But I remember reading in a book that too much alcohol can form a protective film on the surface of bacteria, and it is difficult to kill alcohol completely." Hu Yunpeng was surprised.

"You remember well, but you can dilute it later. Just keep the concentration between 70% and 75% fine. Yang She suggested that the concentration of 95% should only be for the sake of more alcohol, after all, dilution is much easier than purification. ”

Shen Feng explained to the puzzled Hu Yunpeng.

Yang She also nodded and said that this is what he meant, she is worthy of being a girl who is regarded as an opponent by him, and she is quite rich in common sense and knowledge.

"Alcohol is good, it can be disinfected and used as fuel!" Hu Yunpeng clapped his hands excitedly, thinking that alcohol could also be used as fuel.

"According to what you say, adding sulfur to make realgar wine can also repel insects and snakes."

Chen Huimin pursed her lips and smiled, her eyes full of excitement about discovering something good.

In this way, they can be used for multiple purposes, which saves space and improves the use of materials to a certain extent.

"Speaking of insect repellent snakes, do we still need to prepare some anti-allergy medicines, snake pills, and cooling oil?" Chen Sisi said.

"If it's a rainforest-like environment, it's definitely needed."

Shen Feng nodded in agreement, and Chen Huimin wrote down the three types of drugs mentioned on paper.

They plan to discuss the drugs they need first and then choose the brand of drugs.

"Rainforest? If it's very hot, can we learn to make ice out of saltpeter like the heroine in the novel? Tian Mengdan looked excited with honey, she likes to read time travel novels the most, but she didn't expect that one day she would be able to experience it.

"If you want to use the salt, I remember that there is a novel that says that the heroine found the salt field, and the salt flower next to it is the salt!"

"You read a lot of messy novels, no wonder your brain is ......"

"Sisi!" Chen Huimin grabbed her friend and didn't let her finish.

However, even if Chen Sisi didn't finish speaking, Tian Mengdan knew that what she didn't say was not a good thing, but unexpectedly, Tian Mengdan only snorted and ignored Chen Sisi, unlike before, when the two of them faced each other.

"There's a lot of useful knowledge in the novel."

Shen Feng is also a person who likes to read, and said with a smile, "But you are sulfur and saltpeter, plus charcoal, are you planning to make black powder directly?" ”

She quipped, but in her heart she felt that she could indeed prepare some items related to black powder.

Saltpeter, in particular, can also be used to make ice.

Saltpeter dissolves in water and absorbs a lot of heat, making it a must-have for extreme heat weather and can be used repeatedly.

Shen Feng did not forget that in addition to cooling down in the mass extinction, the direct cause of the catastrophe of the end Permian period, which was the most serious 252 million years ago and caused the extinction of 90% of the world's organisms, was excessive temperature.

And predictably, even if you are lucky enough to avoid the heat, the rise in sea levels due to global warming is a problem that cannot be ignored.

If it weren't for the idea of loading a ship into the space that was too whimsical, Shen Feng actually really wanted a boat of his own!

Although she has placed an online order to buy the so-called multi-layer thickened version of the inflatable boat that is not afraid of thorns, wear, scratches, collisions and punctures, it is still safe and reliable without cruise ships.

Although even if the cruise ship could fit into the space, she couldn't afford it.

Of course, there are also fiberglass speedboat-style inflatable boats, and they have been on the World Expo, but the price is ......

Shen Feng decided that in order to comfort the uneasiness in her heart, plus it was an inflatable boat, so she bought a 1.75-meter single model and two 2.3-meter models that can carry up to 3.5 adults, plus a model boat that can ride up to seven adults.

Why buy it this way?

Don't ask, if you ask, the answer is poverty.

Probably because of the quality, two yachts are close to the price of a sleeping bag. You know, the sleeping bag is full of down and other valuable things.

Everyone was actively discussing, and Shen Feng's mobile phone vibrated again.

The caller ID was my cousin, who said that he had arrived at the gate of her school.

- That's not good news.

Shen Feng pursed his lips, hung up the phone, and explained to everyone with great regret that he had to leave first because there was a family member to pick him up.

"It's okay, Fengfeng, go ahead, if there is any result, we will send it to the group at that time!"

In order to record the results of the discussion, the six people also specially formed a group.

"Okay, then I'll go first, and you guys talk slowly." Shen Feng waved goodbye.

In fact, Shen Feng knew that if nothing else, this would be the last time they would see each other.
