Spokesperson of the God of the Universe: the System Asks Me to Collect Taxes

As long as there is civilization, there will be transactions. Since transactions exist, taxes must be paid! What kind of prehistoric land, what kind of super power, what kind of invincibility in the universe, what kind of interstellar overlord... I can't explain it here, I have to pay the tax on it all! Otherwise, it could range from raising taxes to genocide, and it's up to you! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
