Chapter 2528 - Chapter 2592: Celestial Evolution

This Tian Yan Formation has a very domineering name. The so-called Tian Yan is recorded in "Zhou Yi · Xi Ci Shang Zhuan", which states: "The great derivation number is fifty, and its use is forty-nine. Divided into two to represent the duality, hanging one to represent three, using four to represent the four seasons, returning the odd to the remainder to represent leap years, and leaping again in five years, hence using it again and then hanging it. Heaven is one, earth is two, heaven is three, earth is four, heaven is five, earth is six, heaven is seven, earth is eight, heaven is nine, earth is ten. Heaven's number is five, earth's number is five, the five positions are obtained and each has its union. The total number of heaven and earth is fifty-five, and this is how changes occur and ghosts and gods operate."
