I recommend Fist Gang, especially the urban supernatural novel written by Bai. The male protagonist, Li Zheng, rushed into the city with an iron fist. He did not give in to the sinister reality.

I recommend 'Lady's Floating Fist', author: Wind in Heavenly Robe. The female lead, Feng Piaopiao, looked like a lady, but she was not. The male lead, Wei Chu, was a Taiji genius, cold and venomous. 150,000 short and sweet novels, similar to " A Smile Is Beautiful," with a happy story.

However, she was entangled with Wei Chu in Taiji. She did not know what would happen after her identity was exposed. This book had a four-star recommendation index. It was a super short romance novel, fresh and sweet, but not greasy. 'Ancient Warrior Female Agent' was not bad either. The author was Xi Zhen. The female protagonist, Feng Aoqi, had magical ancient martial arts. Her soul traveled through the city and became a special agent. She had a successful career and a one-on-one relationship. The process was light and the ending was happy. "Building a Woman's Kingdom," written by Green Wing Chasing Light. In the female idol category, the female protagonist held high the female idol flag in the male world and walked the beautiful male route. It was a hilarious story. "Journey to the Heavenly Realm," composed by Qi Xia Ye. The young man traversed the heavens, searching for hidden conspiracies. Those close to him became enemies, and he wanted to achieve supreme status. There was also 'The Strongest Son-in-law in History' written by Silent Pastry.
