I Have Just Become the Second Generation Immortal, and the System Wants Me to Become a Goddess?

You may not believe it, but I, Lin Yan, was beaten to death with 1 million yuan. The front foot just won the lottery, and the back foot entered the crematorium. When he opened his eyes again, he was transformed into the top dandy of a family that cultivates immortals—sounds very satisfying? But this body was dug out by his biological father when he was 6 years old and transplanted to his younger sister. Since then, he has become a laughing stock in the world. A mess, for sure. Fortunately, the gold finger that comes standard with travelers arrived as scheduled. The bad news is, the system is a fool. The first step in binding was to get my gender wrong. The compensatory gift package for newbies is called "Transformation into the Goddess of the Nine Heavens" - unlimited time, unlimited times, and unknown cultivation level. I, Lin Yan, am a straight man. You give me this thing? What's even more outrageous is yet to come. The ultimate mission is to let my sister who took my bone praise me for my beauty. The reward is to get the Supreme Bone back and add 10 million in cash. In order to go home, I, a dignified man of seven feet, was forced to wear a skirt with flowing clouds and wide sleeves, and with that face that charmed all living beings, I went to trick my cold sister. Finally, when she looked back, she was stunned: "It's so beautiful..." Mission accomplished. And I jumped over the wall and turned back into a man, facing her chasing me with an innocent look on my face: "What fairy sister? Are you stupid?" This is my daily life in the world of immortality - during the day, I am the good-for-nothing young master who is despised by the whole clan, but secretly, I am the Fairy Bai Yueguang who my sister will never forget. This vest can cover you for a whole day. But the problem is, the idiot in the system has started issuing new tasks again...
