People have their own life beads. After awakening, they are either thought beads or body beads, such as hand strings circling at the left and right wrists respectively. The heavenly bead is like the twin of human beings. When the two beads of mind and body appear on a person at the same time, they are called the heavenly bead. The person who cultivates the body bead is the body bead master, the person who cultivates the Italy bead is the Italy bead master, and the person who cultivates the heaven bead naturally is the heaven bead master. The highest level of Celestial bead master is 12 pairs of beads. Therefore, its cultivation process is also known as the "Twelve changes of Celestial bead". Our protagonist is an archer who practices the transformation of the heaven.
