Wuxia Crossover: I Owe the System Ten Billion, So I Married a Madwoman

Song Shixiong spent his whole life helping others look after Ning Yao. After transmigrating into a nightmarish scenario from the start, he has no choice but to borrow from the System just to stay alive.

As a result, he racks up a usurious debt of one billion faith points to the System. Unable to repay it, he eventually discovers that if he marries the heroine, half of her faith points automatically become “marital property,” which the System can deduct toward his debt. His eyes light up.
