1. Optimize the store refresh algorithm and fix a bug that may cause game crashes during store refresh
2. New automatic backup and save mechanism: Game saves will be backed up every minute (only game progress will be backed up, not battle progress)
3. Fix the issue where the game cannot be saved correctly due to abnormal computer shutdown or other reasons during the save process: Once there is an abnormal save save, the backup save will be loaded for the game. If the backup save also cannot be loaded, a save damage prompt will pop up and the game will be reset to prevent the game from running
4. Fix the bug where accumulated damage becomes negative after exceeding 2.1 billion
5. Slightly reduce the impact of luck on the drop rate
After wave 6.20, all treasure drops will be reduced to 1/3 (boss remains unchanged)
After 7.25 waves, the golden treasure chest has been adjusted from a certain drop of gold and red chips to a certain drop of purple, gold, and red chips
8. Increase the maximum attack speed of weapons (0.025 seconds per attack) to avoid the problem of game lag when the attack speed reaches once per frame in extreme situations
9. Significantly improve the experience required for core upgrades above level 30
10. Tianyan chip: Increase visual field from 30% to 25%
11. Reduced the number of particle effects in the recovery matrix
