The Book of Time

The world is composed of two origins: "Ember" and "Time". When all beings awaken, they need to choose "Ember Cultivator" (burning life to gain explosive power) or "Chrono Sequencer" (controlling time but being counterattacked by the law of cause and effect). The protagonist accidentally awakens his dual origins and becomes the "Apostle of Ember" who has been tabooed for thousands of years.
