As can be seen from the above table, no matter which kind, you have to pay for Spring Cake 2, which means you can change up to 475 kinds. However, the average number of shredded leeks can only be changed to 278, so it is necessary to choose more 1 and 4, and at the same time, the influence of the choice of 1 on the exchangeable capacity of fried leeks and fried bean sprouts should be considered.
