A challenge was meant to be a free fight.
However, to ensure fairness, there should be rules for the challenge.
Swoosh!
Xing Han lifted his big hand and there were explosive beams of light that flew up the sky.
That was obviously two hundred and eight crystals, equivalent to the number of contestants.
"I have already used Spiritual consciousness in these crystals. I have made some markings to track the order of the challenge, from one to two-hundred and eight. Whenever you inject some dark force into it, the markings will be shown and these markings are indelible. You guys go ahead to choose!" Xing Han told the contestants.
This kind of rule meant that every warrior would depend on their own luck to win the challenge.
Whoever was the first to pick his opponent would have a good headstart and a clear advantage.
The marking that was left behind could not be amended. Once there was a change, the crystal would break.
