Li Xun traveled to a country with a highly developed mechanical civilization. He wanted to work hard to obtain citizen points and be promoted to a first-class citizen. Suddenly, he discovered that as long as he learned a basic skill to a certain stage, he could obtain probability points that changed the probability.
30% success rate to break through the bottleneck, use probability points, break through!
10% success rate for finding lost treasures, use probability points to find it!
The probability of defeating your opponent is 50%, use probability points and win!
The deeper the skills you master, the more probability points you have.
ps, the plot is biased toward superpower combat, with various ability settings. Add a bit of cyberpunk mechanical style, and the map will slowly shift from planet to interstellar.
