The little caterpillar can play a permanent big Q, Feihuo. Big Caterpillar can open permanent sharp speed and legend of the night. It can be said to be a permanent concentration camp. Many people like to open worms, and some players even accumulate hundreds of them and open them together. The cost-effectiveness of the caterpillar is very high, but it is very easy to open it, so I suggest that you save a little more before you open it.
