The Little Snake Who Transmigrated Across the Heavens Becomes a Dragon in the City

Bai Tangtang transmigrates into a vast universe and gains the aid of a System. She will run multiple simulations here, exploring the hidden truth behind this universe on her own. Then, with the System's help, she will make her way into the Myriad Worlds.

This is a dragon-transformation story, but she won't start transforming into a dragon until later. She remains a snake throughout the early part, eventually evolving into the Primordial Dao One World Serpent. In the middle, she creates a clone to take the hits for the protagonist across the Myriad Worlds. The clone is one of the Five Phoenixes and Nine Chicks.
