It has a system, including the changes of the twelve gods. The twelve gods of the Universiade will change, so will the twelve gods of the Universiade, and so will the fleeting time.
The changes of the twelve gods in the year of destiny are conditional, and of course there is an independent eight-character rule system, which has been handed down by the blind for thousands of years and used in actual combat. If you don't learn this system and don't understand the conditions of use, how can it be highly accurate, hehe.
