The creator god of the concave-convex world is a very arbitrary god. He created countless planets and people in the concave and convex world, and ruled them as he pleased and without rules - he made some planets rich and beautiful, some barren and desolate, some people enjoyed freedom and happiness, and some people were burdened with heavy taxes and hard labor. The Creator God established seven divine envoys to carry out God's will on his behalf. However, the God of Creation does not deny his people the opportunity at all - if anyone wants to change their destiny and realize their wishes, then go and participate in the "Bump Contest"! Contestants will receive "special abilities" given by the competition system, and will be able to practice and use their abilities to continuously fight through levels. As long as you can win the final victory in the concave and convex competition, you will get everything, and you will be given the power to rule the world on behalf of the gods just like the "Seven Gods". However, these are just hypocritical appearances...
