Traveling Across the Heavens, Committed to Changing the Ending of Bullshit

As the name suggests, Chen Bullshit has experienced nothing but bullshit since he was a child. All these bullshit situations changed when the child reached the age of eighteen and received help from a system. It turns out that his miserable fate in this life was ultimately caused by his innate fate of being lonely and widowed. He could only change his fate by slowly accumulating his destiny through the world-traveling system. The introduction is weak, you can watch it on your own, it may have multiple worlds, multiple ideas, funny writing, the protagonist is a fake guy, and the plot is a bit subversive.
