Traveling through the sky, there is no one to rely on, no golden finger to make the sky explode, and even communication is a problem. What should I do?
At this moment, Chen Guan received a suicide note from his future self!
“What, I died at the age of twenty?!”
“No, we must avoid giving propositions!”
Every once in a while, a suicide note would arrive. In this way, Chen Guan sought good fortune and avoided misfortune, and began his steady life.
Alchemy is just a hobby. Please don’t use your career to challenge my hobby. I don’t want to offend anyone. Thank you!
ps: The protagonist is very talented and doesn’t have a big golden finger, so he can ignore it. He doesn’t dislike Xiao Yan or praise him. If you don’t like him, don’t enter~
