In fact, this is a very casual sign in the sign bucket, allowing you to buy oil supplies. In fact, many sign barrels say oil fines. For some reason, the gods will punish you for oil. The reason is that your heart is not sincere, or your question is circuitous, or you have a problem, and so on. There are many reasons anyway. This kind of lottery is a kind of ability-strengthening lottery in the lottery game, aiming at increasing the authority of the immortals.
Most of the signs in the sign box are ambiguous, and only a few good or bad words are the definite tone (but if the sign doesn't like you, he can turn good words into bad words and let you be blocked). And such fines or reprimands are severe or naked. It doesn't mean anything, just let you contribute more.
