Right at that moment, Shackler Luo Guixing attacked him. All of a sudden, a silver glow was seen in the middle of the arena. The glow was barely there as it seemed to be translucent. Although it could still be seen, the intense spatial waves it made it a little hard to see.
It was then that Tang Wulin and his companions saw that Luo Guixing's body no longer had the three soul rings it had in the past. There were four soul rings that rose from his body this time.
It was true, Luo Guixing had also leveled up to a four-ringed soul master. This fact was one of the biggest source of confidence of their battle today.
He was a four-ringer soul ancestor with two yellow and two purple soul rings, and the soul skill he was using at that moment was his fourth soul skill, Dual-World Division!
