Fireflies rise from humble beginnings, while the bright moon eventually ascends into the heavens. One day, my math teacher asked, “Why is the twelfth lunar month called Layue?” Anyone who has eaten cured meat knows: because there's cured meat, it's called Layue. I didn't look into it, but a random thought made me think this couldn't be right. Which is older, a father or a son? Could a son give birth to his father? So, a math teacher may know the exact values of numbers, but that doesn't mean they know everything beyond them. I wrote this work to help people improve their cultivation, not just math teachers. Of course, whether this cultivation can improve, and whether this spiritual energy can be absorbed, determines whether one can become an immortal. The heavens and earth are home to immortals, fallen down to the human realm.
OK, it's quite interesting to taste it carefully.
