What's the use of the legendary star-gathering essence of Oz?

Ozzie said that the essence of multi-stars has the purpose of cultivating star trails. Star-wheel exploration is a brand-new training resource in the legendary orbit era of Oz, and the training materials of the orbit (Juxingshi, Juxingjing, Juxingjing) are obtained by participating in adventure games. In the first week, the output of cultivation materials doubled, and Juxingjing could be exchanged for the exclusive essence of time and space.
