Fight for the Steam Age

As soon as Chen Qifu opened his eyes, he found that he was buried alive in a coffin! He originally thought there was no hope of rescue, but he never expected that a landslide caused by heavy rain would accidentally rescue him from the coffin... When he walked to a city, he discovered that this place was not modern at all, but the steam age! He traveled through time, but that was not all that surprised him! He found that he had actually traveled through time and became a missing person, and unfortunately, he was targeted by Jack the Ripper... Just when he was dying, a "Tsarist Russian Princess" came out of the dark fog and opened a casino field for him - Russian roulette with a 51% winning rate! After that, every time he bets on his life, the probability will increase by 1%, but correspondingly, he will lose one year of life. And as the probability increases each time, it corresponds to a different gambling game. So in his only 49 years of life, how should he deal with the pressing steps of the genius detective team? Can he use gambling to compete with the entire era of roaring steam and surging dark and evil undercurrents?
