Is it necessary for Jin Shanshan to wake up?

It's not necessary. In the "300 Heroes" game, there is no difference between Jin Shanshan's awakening and non-awakening. The biggest difference is the different appearance, so it is not necessary. "300 Heroes" is a DOTA-like online game independently developed by Shanghai Jumping Network Technology Co., Ltd. and operated by Shenzhen Zhongqingbao Interactive Network Co., Ltd.
