This skeleton is very large, looking not smaller than an elephant.
Xu Yi took out the machete and directly split open its skull.
Inside the skull, there was a blue brain crystal, slightly larger than the brain crystals he had seen before.
Clearly, this was not a brain crystal of a level 3 Fierce Beast.
"Level 4, or level 5 Fierce Beast's brain crystal?" Xu Yi picked it up and sensed it using Spiritual Power.
There was a surging force inside.
"It should be level 4. This is still the activity area for level 3 Fierce Beasts." Xu Yi examined it for a while, then collected this precious level 4 brain crystal.
With this level 4 Fierce Beast brain crystal, Xu Yi felt that he had the strength to deal with level 4 Fierce Beasts.
Before leaving, Xu Yi used his Spiritual Power to scan one more time, confirming there were no other usable brain crystals present, then left with a bounty of loot.
By the time he returned to camp, it was already dark.
