I recommend the novel "What To Do If I Become A Tiger In A Zoological Garden" to you. The male protagonist was reborn as a tiger, but he was locked in a cage and admired by tourists. He was not willing to live like this, so he used the system to help him and was determined to become the strongest. This novel did not involve the cultivation of the system. It focused more on the growth and battle of the protagonist. I hope you like this fairy's recommendation. Muah ~😗
