Building a Doomsday Fortress with a Trillion, The Whole Internet Calls Me Crazy

Suppose the apocalypse comes in a year. I want to build a large shelter that can accommodate a million people. How should I go about it? Waiting for answers, urgent!

Parallel world

A countdown to the apocalypse appeared in Wei Han's mind!

He immediately posted for help on Zhihu, and netizens from all walks of life rushed to offer suggestions!

"When the apocalypse comes, you need to dig deep and stockpile food. Store enough supplies. How do you not know that?"

"Stock up on canned food, instant noodles, and bottled water. They'll be worth more than gold in the apocalypse!"

"Choosing the right location for the shelter is crucial. The perimeter needs to be built with high-strength concrete and steel plates, the interior needs plenty of room, and you need a full arsenal of weapons!"

"Air purification systems, water filtration systems, waste disposal systems, and power equipment are all top priorities. Don't skimp on any of them!"

"Stock up on sugar and fertilizer, and look into making your own kassam rockets."

At first, everyone thought it was just a joke post!

But a year later, when the apocalypse really arrived...

All of humanity was left utterly dumbfounded!
