My grandpa is different from everyone else's; he is a cat. Long before I was even a little child, he was already there, and even when grandpa's grandpa was little, he kept watch by his side just the same. Grandpa once told me, Grandpa Bai has actually always been very lonely. If you can step onto the path of cultivation, you will be able to stay by his side forever. Just like that, I set foot on the path of seeking immortality, and thereby walked into Grandpa Bai's world.
