Jiang Fei couldn't wait to use the big turntable.

After a burst of weird music ended——

System: [Ding - As the old saying goes, you get used to it after a while, the host obtains a "stretch tights"]

Jiang Fei looked at the black stretch tights that suddenly appeared in his hand.

It is a one-piece style.

It can protect from neck to ankles, much like a diving suit.

But the material of the clothes is thin and cold, and feels like chewy jelly.

[Tips: "Stretch tights" are cut-proof, bullet-proof, waterproof, insect-proof, bite-proof, fire-proof, and radiation-proof. They can not only ensure that the human body temperature is the most comfortable 20-25 degrees, but also adapt to all body shapes.

Whether it is 300 catties or 80 catties, it can fit perfectly.

And the "stretch tights" are made of special materials that are dust-proof and oil-proof, and will never get dirty.

Isn’t this a life-saving garment that combines a constant temperature suit, a bulletproof vest, and protective clothing?

That thing!

Jiang Fei put away the tights with satisfaction and used his mind to check the unlocked area.

The remaining white mist on the 7th floor of the supermarket had dissipated for more than half, revealing two large areas.

Like the home textile area on the 5th floor, three extra-long single-sided large shelves enclose an open area.

In the center is a large platform 5 cm above the ground.

One section had a sign that said "Electrical Appliances" and another had a sign that said "Furniture."

The electrical appliance area is equipped with induction cookers, gas stoves, egg steamers, juicers, air conditioners, air purifiers, electric water heaters, washing machines, vacuum cleaners, air fryers, disinfection cabinets, electric kettles, hair removers, hair dryers, curling irons, electric blankets, humidifiers, coffee machines, sweepers, electric toothbrushes, shavers, massagers and other household appliances.

There is only one of each appliance, and there is no brand logo on it. The appearance is all gold, and it looks like a three-no brand.

Obviously, this is an electrical appliance produced in a supermarket.

Jiang Fei checked the furniture area again.

There are basic furniture such as tables, chairs, benches, sofas, beds, cabinets, coffee tables, etc.

Unified simple style, all made of logs.

The style is single, but it is enough for daily use.

Jiang Fei was a little surprised that the furniture was not in gold color.

She thought that everything produced in supermarkets would be golden in color.

Jiang Fei told Lu Yu about the unlocked area.

"We won't be short of home appliances and furniture in the future."

Lu Yu's focus was not here: "Your supermarket even has home appliances and furniture, will it also have medicines?"

"I remember going to a large supermarket before, and it sold medicine."

“Not only that, they also sell snacks there.”

Jiang Fei was excited.

If the supermarket could really unlock the medicines, then her chances of surviving would be much greater, and she wouldn't have to work so hard to grow herbs.

"We won't go back today. We'll try to collect all the gold from this underground gold mine."

Tomorrow and the day after tomorrow are summer and autumn, which will not affect travel. She and Lu Yu can return home before winter.

In order to prevent Xiao Chuxia and the others from worrying, Jiang Fei took out a special walkie-talkie and tried to call the other party.

No response was received.

Jiang Fei and Lu Yu changed places to call.

Only when I reached the entrance did I get in touch with Xiao Chuxia and the others.

"Lu Yu and I are going to collect gold from the mine these two days, so we won't be going home for the time being. Remember to help me collect the crops in the yard tomorrow."

"There are instant meals in the kitchen and refrigerator. You can make them for yourself when you are hungry."

"The food for Dahuang and Xiaohei is in the cabinet in their room."

Xiao Chuxia: "Miss Tuan, you and Brother Lu should be careful."

After cutting off the communication, Jiang Fei and Lu Yu began to concentrate on collecting gold nuggets and ores.

When you are hungry, eat freshly prepared meals from the supermarket warehouse.

When I feel tired, I go to the supermarket to take a nap, and then come out to continue when I wake up.

After two days and three nights of hard work, Jiang Fei and Lu Yu collected all the gold nuggets and ores on the ground in the mine.

Including all ores that can be mined.

[Ding——Gold detected: 135 grams]

[Currently owns gold: 78108864 grams]

[Current unlocking progress: 58%]

Lu Yu: "The ore I gave you just now was the last piece. If you want to collect more gold, you can only mine deeper, but we don't have enough manpower and equipment."

Jiang Fei: "No, let's go home first."

"It's already nine o'clock in the evening. Winter will come in more than two hours. It's too late to drive in the snow. Let's hurry back home."

Jiang Fei walked towards the entrance, his arms so sore that he couldn't lift them.

Mining ore is really tiring.

Lu Yu was equally exhausted.

The two were also covered in dust and dirt from digging for ore, and their clothes became dirty, so they planned to go home and wash them.

As we got closer to the entrance, the sound of heavy rain could be heard.

"Today is autumn, and it's usually windy and sandy. Why is it raining today..." Jiang Fei's voice stopped abruptly, and he smelled a faint strange smell in the air.

Similar to the pungent smell of chemical reagents.

Could it be... acid rain?

Jiang Fei couldn't help but quicken his pace and ran to the entrance.

It rained heavily.

Huge raindrops slammed into the ground and onto the armored vehicle they parked outside.

It is visible to the naked eye that the car body is corroded and full of pits.

Jiang Fei was completely worried.

The last acid rain is more terrible than ordinary acid rain.

In addition to corroding buildings, human bodies, forest vegetation, sculptures, etc., it will also destroy crops, causing land to become barren and pollute water sources.

Even if we manage to avoid acid rain, our future will be half-dead.

Acid rain can release aluminum from a stable state in the soil, polluting the air, and long-term inhalation by humans can cause poisoning.

Blood in the stool, tinnitus, vomiting, anemia, blurred vision, brain damage, slow reaction, and memory loss are the mildest symptoms.

In severe cases, it can lead to paralysis of the respiratory center, renal failure and even death.

This is the death from the sky - acid rain.

For safety reasons, Jiang Fei took Lu Yu into the supermarket.

He used the walkie-talkie to contact Xiao Chuxia and others.

"It's acid raining outside now. Don't go out or stay by the window."

The roof of the brick house is covered with plastic sheets and slates, which are not easily corroded by acid rain and should be able to survive three acid rains.

She remembered that there were three acid rains last year.

The first session lasted two hours.

That night, the second rain came and it rained all day long.

The last one was two days later. It only rained for more than ten minutes and then the acid rain completely ended.

But the order and duration of this natural disaster had changed, and she could only use the last acid rain as a reference.

Xiao Chuxia's voice came from the other end of the intercom.

"Little sister, you and Brother Lu, don't come back yet. I'll tell you when the rain stops."

"If you are accidentally exposed to acid rain, rinse with sodium bicarbonate solution. We all have this in our medicine cabinets."

Sodium bicarbonate has the effect of cleansing the skin and can disinfect and kill bacteria, so Jiang Fei had put it in the medicine box before.

"If you need anything, please contact me via intercom."

After turning off the intercom, Jiang Fei took Lu Yu to the big wooden house in the residential area of the supermarket.

When Lu Yu saw the wooden sign with the words "Jiang Fei Lu Yu" hanging on the door, he was startled.

"This is?"
