Planned in the Genshin main line killed, all countries and regions after all the characters are open, the second creation of the concert will be complete and balanced samples, then re-fine-tune the model and add the reality of the style of screening to assist the game of the various countries output gatekeepers, in order to enhance the output of the differentiation and quality. | |
