Turn into a Mouse to Cultivate Immortality

You can turn into a mouse, what else is impossible? Chen Xuan traveled to a world of cultivating immortals where the weak preyed on the strong. He was thrown into the forest at the beginning and almost starved to death.   He had neither background nor cultivation, and he couldn't even gather the resources for cultivation.   While escaping for his life, he accidentally gained the power to transform into a mouse.   After transforming into a mouse, he can drill holes through walls, steal the sky and change the weather, and can also steal various cultivation resources.   Relying on this ability, he quietly traveled among the major sects, stealing spiritual stones, elixirs, and techniques.   While others are still practicing hard, he has been relying on the stolen resources to soar all the way, and his cultivation has improved by leaps and bounds.   In the future, he will transform into a fairy among rats, pretending to be a pig and eating a tiger, stealing all the way to the peak of the fairy world, and he will be so happy that he can fly!
