I Have 108 Older Sisters

"Yu Tian's only remaining family, his younger sister, was diagnosed with leukemia, and they needed 2 million for the bone marrow transplant. There was no way the poor siblings could afford that. Just as Yu Tian was completely devastated, a red Lamborghini stopped in front of him. The lady in sunglasses who walked out of the expensive vehicle told Yu Tian that she was his long-lost older sister. She then transferred him 3 million to solve his current problem. "Come on. Come back with me. All of your older sisters are dying to meet you." "Um... How many older sisters do I have?" "Why don't you guess?" "Two? Maybe three? There's no way I have seven or eight older sisters, right?" The lady shook her finger and smiled. "Including me, you have 108 older sisters." Yu Tian's eyes widened."
