Add a new system AO-SYSTEM.
AO-SYSTEM has three passive abilities :
1. Increase the upper limit of Astral energy.
2. It has a certain chance of not losing Astral after death.
3. It has a certain chance to get the buff after reviving.
The above three passive abilities will increase their effectiveness as their level increases.
The system will start when the second backup occurs.
