Lin Ye, the car god in his previous life, was reborn into a racing world where man and machine are integrated.
The racing cars here are transformed from "machine girls", their souls are synchronized, and they share the same body.
Others started with a top-notch mecha, but when he woke up, there was only a scrapped mecha [Night Shadow] picked up from a scrap iron yard - the stability was 10%, she would die at any time, and there was no money to repair her.
The only way to survive is to get into the dirtiest and most violent underground racing track.
Using the borrowed "empty car body", he dragged the dying Ye Ying to fight against the desperadoes on the track and the overlord Ye Han who ruled here.
"She said she wanted to run."
"Then I will take her from this underground abyss all the way back to the track under the sun."
