If you are looking for a recommendation for a time-travel novel set in Russia where the protagonist earns money, I would suggest "重生俄羅斯當寡頭" by 琉璃灣. This urban novel tells the story of a character who is reborn in Russia during the turn of the century and embarks on a journey to become a tycoon. The book explores the protagonist's growth and experiences as they navigate the challenges of being in a foreign land. Although I cannot provide a detailed summary or review, this novel seems to fit your criteria.
