Chen Jiu transferred to a new and only hidden profession, the "Weapon Master". He unintentionally fused the Yin and Yang jade pendant brought by time travel and obtained the chaotic space. The professional weapons opened up his intelligence in the chaotic space. Chen Jiu has lived a life of being useless ever since.
When a rusty sword has percentage damage, when a cooking spoon has an extremely huge size, and when a picture book has the darkest means of killing, the enemy will know what cruelty is.
When the chaotic space turns into the chaotic world, and when a new professional system appears, the impact on the world will be terrible.
When the weapon master becomes the realm master, the secret realm of this world will tremble.
"Hey! Classmate, you are so strong. I know a secret realm. Do you want to try it?"
"Hey! Friend, you are almost dead. I have a chance to transform your race. Do you want to try it?"
Who does the protagonist end up with?
