The Time Flow Formation of the Dao Opening Sect was a world as large as a Middle Thousand World. However, this world did not have anything like forests, mountains, oceans, etc.
It was a green world; the sky and the earth were all green, making the entire thing somewhat eerie. Only two people lived inside that world: Wang Tian and Wang Wei, and they separated themselves by a great distance.
Wang Tian dug a cave underground to reforge his Primordial Spirit and enter the Duyi Realm. Meanwhile, Wang Wei created a small cottage with the Heaven Concealing Array surrounding it.
He wanted to use this seclusion to catch up with his peers in cultivation.
Once the retreat began, he did not immediately enter the next realm but ensured that he indeed cultivated his Yang God to the absolute peak. Then, he began to break the shackles on his body.
