Chapter 900: Chapter 501: Sweeping Through the Secret Realm

Ye Feng looked at the Crystal Core in his hand, his expression revealing a slight surprise.

He could feel that it contained an extremely pure and vast amount of Spiritual Energy. If he absorbed it, he could rapidly enhance his strength.

Ye Feng estimated that absorbing about five of these Crystal Cores would be equivalent to one Spirit Element Pill.

It was worth noting that even for the Elders' official disciples, they could only obtain ten of these pills per month.

For the ordinary members of the Heavenly God Court, they received even fewer, at most one or two pills a month. But here, by killing a dozen or so beasts, he could achieve this goal.

When you really consider it, killing the beasts was definitely simpler.

In addition to that, these Crystal Cores also contained a huge amount of Life Energy, which could quickly heal someone else's injuries.

Ye Feng surmised that the effect of these Crystal Cores should be comparable to a Seventh Order Fruit of Life.
