Before a normal battle, these Beastmen could first inject Battle Qi into these Fierce Beast Crystal Cores, then use them during combat.
If following standard procedures and wanting to ensure the modified body's life, then the best choice for these Fierce Beast Crystal Cores would be Crystal Cores from Silver Tier Fierce Beasts.
Because a single Silver Tier Fierce Beast Crystal Core can store Silver-level Battle Qi, and it also has better output capability.
After all, having to bury a Fierce Beast Crystal Core inside the body is itself an extremely high-risk matter.
If the Fierce Beast Crystal Core were to undergo an Energy conflict, or get hit and cause an Explosion, then the modified body would be blown to pieces.
But now, under Fang Zhou's suggestion, there was no need at all for Silver Tier Fierce Beast Crystal Cores—Silver Tier Fierce Beast Crystal Cores are so expensive.
