Flowers need to be spent playing Qin when doing famine power, or getting injured, so that they have a chance to gain famine power (the higher the level, the greater the chance). After level 20, you can absorb the power of famine and become a demon god (the higher the level, the longer the duration). The power of flower famine is the body of a demon god, who can kill all the immortals in the sky and release the power of famine by assembling ten artifacts.
