C49 Xi sanmo died in a car accident

The car accident that Xi Sanmo repeatedly mentioned happened when she was seventeen.

In the autumn of her seventeenth year, for some reason, Xi Sanmo suddenly drove a black Buick to the outskirts of the city. The road she walked on had no roadblocks and few cars, but it was on such a road that she experienced a very serious car accident.

She didn't crash into the car, she didn't chase after it
