Nine students arrived at Tiantu Mountain, where Teacher Taitan had already set up the practice field in the open wilderness.
The first lesson of the Earth Magic Course practiced the Circular Burrow Escape Skill, the second lesson practiced the Linear Burrow Escape, and this lesson was to practice the Broken Line Burrow Escape.
In front of Teacher Taitan, there were two rows of small trees hanging with colorful markers, ten in each row. The students needed to perform a "zigzag" movement using the Burrow Escape between the two rows, and each time they reached a small tree, they had to emerge and pull off a marker from the tree.
Each small tree had markers of different colors hung on it; after completing the zigzag movement, they then had to use the Linear Burrow Escape to return to the starting point and hand over ten different colored markers to Teacher Taitan as a sign of completing the trial.
The task for this lesson was twenty times, the same for everyone.
