Ordinary man Li Shengdai leads a mundane and difficult life. As a poor but good man, he donates his only savings to those in need. However, one day, a beautiful girl, Hu Xuedie, suddenly appears at his door with a strange contract, marking the beginning of an unknown and mysterious turn in this ordinary story... One merit point can be exchanged for one minute of life. Doing a good deed earns one merit point.
Committing a bad deed deducts one hundred merit points. Saving a mortal earns ten merit points. Killing a mortal deducts one thousand merit points. Saving a good person earns fifty merit points. Killing a good person deducts five thousand merit points. If you have enough merit points, then congratulations, immortality is no longer just a dream!   ---    "Eighteen thousand five hundred and three years old?!" "Hiss!" Seeing that Ximen Xiaoxiao did not refute, everyone present gasped and stared at Ximen Xiaoxiao with wide eyes. Eighteen thousand five hundred and three years old.
This young lady in front of them was definitely the longest-lived person they had ever seen in their lives.
