Su Wan gazed at the crystal core, which emanated a bluish light. Her face was solemn.
This crystal was the key to breaking the seal and freeing the Fire Elemental Lord. It was also the key to their rewards.
Su Wan gestured to the giant lizard to take down the crystal core. To everyone's surprise, the giant lizard couldn't get within five meters of the altar.
It couldn't get through the force field at all.
Su Wan frowned. She commanded a Battleaxe Warrior to try. The outcome was the same.
Perhaps it required someone of stronger mana! The crystal had been stored here for so many years. The power was so great that it created a force field that nobody could pass through.
She glanced at Xu Yuan. He was the only one who could lift the crystal. "Xu Yuan, please help…"
Xu Yuan approached the crystal. The blue light repelled him. A gray light emanated from Xu Yuan and poured into the crystal. The gray energy devoured the blue one slowly.
