1. First of all, the upgrade indicator is the experience value. Only when the experience value of each level is enough can you upgrade. Click on the avatar in the upper right corner to bring up the profile page. The first line in green is the empirical value.

2. Experience value can be obtained through daily tasks and order tasks, which is the most convenient way.

3. If you want to pursue the experience value, try to choose a difficult order task to complete, such as blue or purple, and the experience value is attached. At the same time, you can open today's advanced treasure chest to get gold coins.

Another effective way to increase experience is to get food by cooking or playing tricks. Eat these directly, and you can gain experience to help you upgrade quickly. However, there is a limit to the food you can eat every day. There is a satiety index on the right side of the avatar. If you exceed this index, you can't continue eating.
