Transmigrating to Another World: Am I Not Human?

[No Fixed Couple + Multiple Male Leads + Quick Transmigration + Ensemble Cast] [All Male Leads Are Virgins] Chu Fengci was a top-tier corporate drone in the modern world: greedy for money, lustful, and selfish. Those were the labels other people gave her, but they were true enough. She worked nine to five every day and sometimes delivered food on the side. But one night, while unwinding and watching videos, she laughed so wildly that she choked on a mouthful of water and died, forced to leave this beautiful world. She was also forced to leave behind the money she'd spent half her life scrimping and saving! She was furious, but there was nothing she could do. But when she opened her eyes again, she had transmigrated. And she wasn't even human. She was a cow. What kind of disastrous start was this... She thought fate was playing a joke on her, but then she transmigrated into a cat... The third time... The fourth time... She gradually began to fall apart, but she also made a demand of the System: after completing her mission, she had to become human. She mustn't steal anyone else's body or identity. She had to create a nonexistent identity of her own in that world. Most importantly, she could only be called Chu Fengci.
