Patch v1.15 updated

Modifications:
· Adjusted the mechanism of "Spear of Purify", now it will not deduct physical attack multiplier due to any other equipment with negative health regeneration.

· Fixed the bug that the battle process might not match the battle result in some cases

· Fixed several incorrect tile passages

Thanks to all friends who found bugs and made comments, and happy 2023 & the second anniversary (though a little bit late)!
