In this extremely short span of time, Di Heng and Di Hui only just managed to react. It's not that their reaction speed was slow, but Su Chen appeared too suddenly, and Su Chen had locked onto Di Xi earlier, so they felt nothing at all.
It wasn't until Di Xi's heavy saber light clashed with Su Chen's sword light that they realized what was happening.
Before they could help, or even catch a glimpse of Su Chen's figure, Di Xi was already dead, turned into nothingness.
"Who is it?!" Di Heng's expression turned incomparably serious, and he roared.
Although it was an ambush, instantly killing Fourth Elder Di Xi is extremely difficult.
At least, Di Heng himself was not confident in doing so.
In other words, the opponent's strength was at a minimum at the Fourth Level of the Human Lord Realm, if not more.
He couldn't figure out who it was.
Among those who reached the Fourth Level of the Human Lord Realm, there seemed to be about ten out of the thirty-six people who entered.
