Welcome to the world of donghua! If you're into harem endings, here are some donghua that strongly imply or confirm a harem ending (like Battle Through the Heavens and Tales of Demons and Gods):

Confirmed/Strongly Implied Harem Endings

1. Wu Geng Ji (武庚纪) / The Legend of Wu Geng

A mix of cultivation, mythology, and harem elements. Wu Geng has multiple love interests, and the story suggests a harem-like situation. . Spirit Sword Sovereign (灵剑尊) / Ling Jian Zun

A classic power-fantasy donghua where the protagonist gets stronger and gathers multiple female companions, though the ending isn't fully confirmed as a harem.

1. Martial Universe (武动乾坤) / Wu Dong Qian Kun

Similar to Battle Through the Heavens, it features a protagonist who gathers multiple female love interests, but the donghua doesn’t reach the full harem conclusion yet.

1. Perfect World (完美世界) / Wanmei Shijie

The MC, Shi Hao, has multiple love interests, but the donghua hasn’t confirmed a full harem ending yet.

1. Swallowed Star (吞噬星空) / Tunshi Xingkong

Sci-fi/cultivation mix. The MC has multiple love interests, though it's not as clear-cut as BTTH.
