Introduction: What should I do if I cross to another world and become an NPC? This idea has been deeply rooted and sprouted in William’s mind! Therefore, he decided: I want to be the strongest NPC in history. Wear the thickest armour and give the most vicious beatings! Who says an NPC will be killed by players? Who says an NPC upgrades more slowly than players? Who says an NPC must explode equipment, I can explode in more ways… Bah humph. Anyway, it’s impossible for me to die. Just take a look at all you trash players. Your father will stand here and let you chop for an hour without a frown!...
