Starting with a Wooden Stick, I Became Invincible by Killing Monsters

Gu Changge traveled to a world full of monsters. He got a system where he gets points by killing monsters. With points, Gu Changge can exchange for anything. Martial arts, magic, super powers, as long as you can't think of it, there is nothing you can't change. Alas, alas, no, what age is it? You still have to practice to level up, but like me, I just need to kill monsters. Don't compete with me for monsters. Get out of the way, this monster, let me come. My little cuties, I'm here for you again. When Gu Changge appeared in front of the monster with a nuclear bomb in his left hand and a watermelon knife in his right hand with a Gundam standing behind him. The monsters went crazy. Look, that lunatic is here to kill us again. Everyone, run away. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
