Reborn as an Extra with the SSS-Divine Debt System and my Past Skills Novel

[Congratulations, you have earned +9 coins. You have repaid 999,999,999 / 1,000,000,000 Coins. You need 1 more coin to repay your debt.] “You’ve got to be kidding me.” ______ After living a hundred lives, Lucian finally managed to repay his debt to the system. World after world, he fought, bled, and struggled—all for the freedom he had foolishly given up the day he begged the system to save his life. At last, he had done it. 999,999,990 coins. Just one more mission, one last world, and he would finally be free... Or so he thought. But this was no joke. The system had screwed him over one final time. Still, there was hope. With only a single coin left to repay, the system could no longer play its tricks. Freedom was just within his grasp—if he could survive this last world. All Lucian had to do was reach the end. Simple, right? Except this time, the world itself seemed determined to destroy him.
