To Xiao Qiang, he already knew from Xiao Nanshan what a heavenly thunder talisman of the earth rank meant.
In this world now known as the age of the end of the law, the heavenly thunder talisman was already rare, let alone a heavenly thunder talisman of the earth level. According to Xiao Nanshan, an ordinary person's heavenly thunder talisman could generally be successfully drawn by a martial artist at the foundation-building stage, while an earth-level heavenly thunder talisman could only be drawn by a martial artist at the golden pill stage or above. As for those at the Nascent Soul stage and above, talisman was no longer their primary means of fighting their enemies; they battled with magic treasures and their cultivation levels instead.
