My apocalyptic heroine has come true

I, Fang Ming, am the only survivor of the plane accident. My parents and relatives have left me, and I have become a disabled person.
I do not want to live.
I, Xia Xiaochi, am the only survivor of the shelter explosion. My parents and relatives have left me, and I have become a disabled person.

……
By chance, Fang Ming, who was at the lowest point in his life, came into contact with a doomsday survival game.
In the game, the heroine encountered the same accident as him.
The same thing, but she made a different choice.
Fang Ming deeply admired her strong will.
He can't save himself in reality, but he can save the heroine in this game.

Fang Ming closed his eyes and rushed forward.
With his powerful money ability, Fang Ming not only rescued the heroine, but also built the strongest shelter in the apocalypse.
Now, he watched the heroine he had personally raised walk in from behind the door wearing power armor.
Fang Ming was dumbfounded.
"I'm here to repay you," she said.
