Into the Unknown
The desert stretched endlessly before us—scorching sun above, waves of sand below. Our expedition team was heading straight into the infamous “Corridor of Death,” a barren no-man’s-land where countless journeys had failed.
The only thing we trusted to carry us through?
A roaring Caterpillar C7.1 Electronic Injection Engine.
At dawn, when the key turned, the 7.1L inline-six diesel heart awakened. Its precise electronic fuel injection system delivered power with razor-sharp accuracy. Every roar was like a battle cry, promising strength against the unforgiving wilderness.
[Horror Tales] Caterpillar C7 Engine at Midnight
1. Abandoned Mining Area
Amid the desolate northwestern Gobi Desert lies a long-dormant open-pit mine. Winds and sand howl year-round, and the shattered mine cars, collapsed conveyor belts, and rust-corroded machine rooms create a scene reminiscent of a dead city.
Lin Tao, a buyer of used construction machinery, received a strange commission: someone offered him a high price to dismantle a Caterpillar C7 engine from the abandoned mine.
"This engine is long dead, and it wouldn't fetch a penny," his assistant, Lao Zhang, said with a frown.
"The client specifically requested a C7 and was willing to pay three times the price." Lin Tao lit a cigarette, his eyes piercing.
So, they drove to the silent mine.

Hello everyone, this is your old friend, the Chairman of the Construction Site Literature Association. Today, I'm not going to tell you about a love story or a fantasy tale of immortality, but about a creature more formidable than any hero—the Carter C18 engine.
When I first saw it, eight words came to mind:
This isn't an engine, it's a divine beast from heaven!
