In the world of cultivating immortals, spiritual roots are used to judge the level and the golden elixir determines the future, but Lin Yan took a different approach. Occasionally, I came across the inheritance of ancient wood, and realized the wonders of the world of mortise and tenon. I used ordinary wood to make utensils, and used ingenuity to construct the Tao. Building things is to cultivate the Tao, and the interlocking mortise and tenon joints are the foundation of the Tao. A small wooden house is built to protect the wind and thunder, a large fairy tower is built to control the stars. One tenon penetrates the hole, and one hammer connects the gods. Let's see her holding a carving knife and swinging an ax to chisel, using the skill of tenon and tenon to carve out the path to heaven and immortality for the builders in the midst of the contending of thousands of immortals!
