How to pass the secret teaching line of Sudan
After opening the side image of God, starting from the spiritual vision to 1, there will be constant "spiritual war" events, which will make the protagonist think about the essence of the world, and will add connections to the righteous gods and evil gods or doubts about them according to the results of the thinking. Adding the value to a certain extent will trigger the sermon ritual (limited time), and then follow the plot.
I don't know how to determine this value, but it is fixed to think about the relationship between Orthodox faith and the relationship between Orthodox God, and to think about the relationship between Tantric faith and evil gods. I doubt I can get it stably by rationality (it sounds like it but I haven't tried it).
