Reborn, I Swapped Fateful Spirit Pets with My Younger Sister

Mom took my younger sister and me to buy lucky spirit pets. I fell for a little white snake at first sight. My sister thought snakes were scary and hard to care for, so she chose the easiest pet to raise, a loach. They said it took a loach a whole year to recognize its master, so my sister pampered it carefully. But it died in less than six months. After I started raising the little white snake, I was hired by a foreign company and won tens of millions in the lottery. My sister went mad with jealousy. She said snakes ate loaches, and accused me of making my snake steal the loach's good fortune. While I was off guard, she pushed me into the moat. When we were both reborn, my sister snatched the little white snake first. She had no idea. Snakes are creatures of dark yin energy, and they choose their masters themselves. Force one to accept you, and it will turn on you.
