Reborn with Modern Weapons

This is the story of an old guy who spent seventy or eighty years in a high-martial-arts world, then returned to his youth and activated an Achievement System.

Well, just beating up all the scumbags he met in his previous life definitely won't be enough! Quietly keeping his head down and farming isn't what he wants out of life, either!

If he sets his sights on killing any god who stands in his way and slaying any Buddha who blocks his path, then throws a party in the Supreme Divine Hall, will they tie him up and dunk him in a pig cage?
