Let me explain

Ming put down the telescope, brushing through the chat channel, waiting for Da Vinci to return home. Actually, he was quite looking forward to the zombie that it would bring back, with pure anticipation for scientific research.

"Do you have nothing better to do? We should chat about those big shots on the level leaderboard. Do you think Ming is the strongest?"

"You're really idle, aren't you preparing for the zombie wave tonight?"

"What is there to prepare for? As long as there are no elite monsters appearing, there's not much of a problem. Even if there are, I'm not afraid. I have saved enough money. Once the doomsday trading line opens tonight, I can buy two professional skills in one go. Even if it's an elite monster, I can kill it!"

"Buying two at once? You must have saved a lot. I've checked the professional skills, and the two cheapest ones add up to 1500 gold coins."
