My Six Cute Loli Girls

My name is Bai Xiaobai. I was taking a shower. A huge wave came and I was inexplicably involved in this world. In this world, I got the help of a system named Ruoruo. I will show you how I upgraded step by step and reached the pinnacle of life. "What? You said there are six cute loli girls here?" "What? I can upgrade even if I drink water?" "What? Am I a water spirit?" In this world, you may not survive the first chapter without systematic help, and I am the chosen one.
