Zyron's plan of waiting for the formation to run out of effect wasn't bad.
After all, it was only Xu Feng who could confront them whereas the other tank was occupied in dealing with the Colossus.
And on the off-chance, Zhao Kai finished the battle early and joined Xu Feng. It still wouldn't change much, given Zhao Kai's skills would be in cooldown and his mana should have been expended.
With that being in the factor, only Xu Feng who was a healer could possibly damage them.
'Hmph, just stay arrogant and continue yapping.' Zyron sneered inwardly.
The reason why he even made his threat was not to spout a third-rate villain's line. But it was to distract Xu Feng and force him to respond to him. Thus, allowing them to continue to stall for time.
