Indestructible Wall is a naturally formed unique stone wall that contains natural Heavenly Dao Patterns. It boasts excellent defensive capabilities and recovery ability.
Those whose attack power has not reached the True God Level can't leave even the slightest mark on the Indestructible Wall. Even for True Gods, any marks left would heal very quickly.
Generally speaking, the depth of the marks a First Tier True God could leave on the Indestructible Wall wouldn't exceed one centimeter. For the Second Tier, it wouldn't exceed two centimeters; for the Third Tier, three centimeters... and so on.
Thus, using the Indestructible Wall for testing makes it very easy to gauge the tester's attack strength.
As the testing began, each participant's results were recorded on their respective Identity Tokens. To demonstrate fairness and transparency, the data for everyone were also displayed on the massive screens projected in the sky.
