Time is of the essence. I immediately called the supermarket to have them deliver the goods to my doorstep.

20 bags of flour, 20 bags of rice, 5 bags of various cereals, 20 barrels of cooking oil, 10 boxes each of salt, soy sauce, vinegar, white sugar, and brown sugar, 200 catties each of dried goods such as wood ear mushrooms, shiitake mushrooms, and vermicelli.

Various snacks, dried fruits, beef jerky, sausages, instant noodles, spicy and sour noodles, and ten boxes of my favorite snail noodles.

Canned powdered milk, soy milk powder, oatmeal, coffee powder, soy milk powder, and so on.

Next are bath and hygiene products, especially sanitary napkins. I had the supermarket deliver all their inventory.

Then comes the electrical appliances. There's an appliance store near the residential area.

Four air conditioners, three rice cookers, six electric woks, ten electric kettles, ten induction cookers, and ten electric blankets.

Remember, natural gas will be cut off in half a month after doomsday.

To have a meal, we must rely on solar energy.

After doomsday, the temperature rose sharply, and it was sunny every day. It continued like this for a year, followed by a sudden drop in temperature, and heavy snowfall for several months.

So, I need to purchase a few bottles of gas, and even a stove and coal briquettes.

This way, when the solar power is unable to supply electricity during heavy snowfall, I can burn coal.

No sooner had I hung up the phone than I heard someone knocking on the door.

Looking through the peephole, I saw my best friend and a tall man, so I opened the door with relief.

My best friend spoke quickly, "This is my younger brother, Xing Feng. He just got off the plane, and the airport was sealed off. We can't leave now."

It seems the government has realized something is wrong and wants to prevent the spread of the virus. We can't leave now.

Time is of the essence. I showed them the prepared list and asked them to see if anything was missing.

My best friend took a look for a long time, then looked up at me with a hint of sadness in her eyes.

Her gaze made me feel uneasy.

I know she still has many questions in her mind, but we both know it's not the time to discuss them.

My best friend comes from a wealthy family, so we don't have to worry about money. We decided to continue buying, and we made detailed arrangements.

I continued to purchase supplies, while my best friend went to her classmate who works at a pharmacy to buy medicine.

Xing Feng is an electrical engineering major, so it's his task to buy refrigerators, modify the main door, handle water and electricity, and install water purifiers and solar power generators.

Following the online guide, I also bought twenty sets of bedding, various clothing for all seasons, several boxes of underwear, 50 power banks, four drones, a high-powered telescope, pepper spray, hemp rope, high-intensity flashlights, and so on.

Regardless of whether they will be useful or not, as long as they are mentioned online, I bought them all.

Xing Feng had the door replaced with a blast-proof door comparable to a bank's vault. Even the glass was bulletproof. Starting from the 23rd floor, all the way up to the 28th floor, each staircase was equipped with a stainless steel door.

There was also a door outside the elevator.
