Lord Krune

Ten days later, Krune finished obtaining the effect from the Tier 3 Essence, now weighing 490 kilograms, just 10 kilograms short of reaching the peak of Tier 2. 

Seeing how closed he was, he wished to perform an experiment. Since he already incorporated the effect of the Tier 3 Essence in his Ocean Heart's development effect, he wished to see if he would face any obstacles once he reached the peak of Tier 2 or if the development effect would take him straight into Tier 3. 

It was only possible for him to experiment now when the cost was cheaper and the time required was less. If he tried this in Tier 4, it might cost a lot more. After all, Wrister had to hunt a Demon Emperor to obtain a Tier 4 Demon Core.

And to do that, he had to risk his life. Plus, it wasn't guaranteed that he would emerge victorious all the time. Nevertheless, Krune laughed when he reached 500 kilograms in weight. And the next day, he reached 501 kilograms without any hindrances.
