Sorry, need to rant a bit.
So the 1st Celestial Deity and 1st Martial God made a big doodoo, tried their best to resolve it but end up dead.
But the Martial God created a sucession system! Great! Then the first fucker stole all the benefit out of it and refused the call to fix the problem, causing the seond successor to be lobotomized and the third, who is MC, to be hunted like a dog.
