Immortality: The Days of Trading Life for Money

[Latest Update]: Li Changsheng's current total lifespan is 138,761.2 billion years. Li Changsheng died alone in his old age, and after being reborn, he had a character panel. Paying real money increases lifespan; one or two coins equals one day of life. One free attribute point is gained for each day you live. Li Changsheng is a man of survival. As long as he can survive, he has unlimited lifespan. He was reborn in a parallel universe similar to the time of World War I. He went to Africa to pan for gold right from the start. He was digging for gold and spending money to buy his life. It wasn't until Li Changsheng gained a lifespan of ten thousand years that he suddenly realized that this was only the beginning of a wonderful life. Li Changsheng possesses the talent of "time travel," allowing him to travel through time and space to other worlds. During the Great Western Dynasty, Li Changsheng overthrew the corrupt court, established the Great Tang Empire, and collected gold to gain a million years of lifespan. In the Dragon Realm, Li Changsheng obtained a martial arts inheritance, slaughtered the Black Dragon Clan that had invaded the human race's territory, and obtained the Dragon Pearl. He could exchange one pearl for ten thousand years of lifespan, thus increasing his lifespan by more than ten million years. I recently heard that Li Changsheng clashed with the Five-Clawed Black Dragon from the Upper Realm during the Dragon Transformation and Ascension Ceremony, and used the Ice Phoenix Intent to kill the Five-Clawed Black Dragon.
