Although the Mini World had not been completely refined by Lin Feng, the Heart of the Netherworld was the core of the Mini World, therefore this Mini World could be considered Lin Feng's own.
Here, Lin Feng could be said to be the absolute boss, not at all afraid that Zhang Sheng and Wei Feng would harbor any ill intentions. Should they truly harbor such thoughts, Lin Feng could simply extinguish them with a single thought, effortlessly!
However, Zhang Sheng and Wei Feng wouldn't commit such foolish acts, having witnessed Lin Feng's strength themselves, as well as his possession of an independent world, which they, being mere Yin spirits, could not possibly contend with!
Besides, once they left this Mini World, they might be captured or dealt with by others, and then there would be nowhere to even cry!
What's most crucial is that Lin Feng had once promised them, given the right opportunity, he would avenge them!
Hatred, after all, was the most important thing in their hearts!
