Every Life I Borrow Must Be Repaid

In this world, the poor can sell off the lives they never lived. Some sell the future of "if I had studied medicine" to pay tuition, some sell the possibility of "I could have left my hometown" to settle debts, and some even mortgage all their life choices to others in advance. Xu Zhaochuan also sells. He owes 312 heng yuan, and even his landlord is starting to worry whether he can walk back on his own after the auction. But just as his "doctor life" is sold, someone in the auction hall is critically injured. Xu Zhaochuan stares at the buyer for a few seconds and does something very unscrupulous—he borrows back the life he just sold. Ninety seconds later, the person is saved. The buyer also calls the police. From that day on, Xu Zhaochuan discovers that all the people he could have become can still come back. Doctor, swordsman, merchant, craftsman, investigator... The more he borrows, the stronger he becomes. And the more he owes. Until one day, he realizes that the prosperity of this world is built on the countless futures that have been sold off. And someone is preparing to leave everyone with only one life from now on. — Description from novelcodex.org
