662 Chapter 301: The Giant Turtle Roars to the Sky, Fighting the Battle Demon Lord

"Jack, you... suddenly becoming so monstrous is a bit too much for me."

Sitting on a giant stone turtle statue, Justin Welan looked at Jack Clark's Purple Killing Energy skyrocketing by 90,000 in one day and couldn't help but feel somewhat shocked, even though he was already used to it.

More than 90,000 Purple Killing Energy, that means he had slain tens of thousands of Level 5 polluted monsters in one day.

Tens of thousands of Level 5 monsters – even if you add up the entire Eastern Summer Academy students from all three grades of Martial Cultivation, the count wouldn't reach 10,000 Fifth Layer Heaven cultivators.

Of course, with the Void Creatures on the outskirts being almost cleared, there were hardly any level 5 monsters left.

The Void Creatures Jack Clark killed today were probably Level 6 and above, a large number of Level 7, and that's why his Purple Killing Energy increased so much in such a short time.
