When he killed the older birdman, he got three rewards.

The first reward was 10000 units of the essence of nature which he transferred to the inner world to increase its richness in the essence of nature.

The second reward was the demi king realm essence gem, which he just checked.

The final reward was an additional reward for killing a Demi King realm cultivator and it was a special reward box.

'Should I open it or store it for an emergency case?' When he saw the system notification, Ajaxa's first thought was whether to open it or not?

Since it was known that a special reward box would give a required item that would help him for his present situation. So, after thinking for a moment, he decided to not use it.

'Instead, I will open the two mysterious reward boxes from the missions,' He quickly shifted the boxes from special to mysterious rewards box which would give a random item.
