Lu Heng looked at the remaining three individuals and asked again, "Those who already have Third Transition Source Material but wish to change it, step forward now."
This time, two more individuals stepped forward.
Finally, only one person remained at the back. He was the highest-ranked among the ten, with a Source Energy Level of 40 and had already obtained a Third Transition Class.
As such, he couldn't participate in the competition for the two pieces of Third Transition Source Material.
This Level 40 Superpower Soldier was called Cao Lixiong, the one with the highest Source Energy Level among the ten.
Because of his high level and strong Combat Power, he had succeeded in a previous call to arms through a Source Material battle and obtained a complete Third Transition Class.
His Third Transition Class was "Energy Shield Guard."
This was a Defense System Class, with very strong defensive capabilities, which could also provide defense in water.
