I'm a cracked version of the game. I also ordered many times to do this task. The one with the most experience in cooking didn't respond. I still don't believe what I said online, but after I finished cooking for more than a dozen times, I cleaned the dishes for a long time. Suddenly, it said that I had upgraded, so it was really necessary to cook more. On the basis of the original, I did it for more than ten times before I got to Level 4. Those who didn't cook much would insist on it for longer.
