Su Yu's words made Ada ponder slightly, reminding him of the miraculous Giant Will within his body. Indeed, he didn't need to fear, and now Ada also felt a strong curiosity towards the Netherworld Skull.
Su Yu himself became curious about the Netherworld Skull, and with the Giant Will slumbering in his body, having devoured what was known as the most perfect "999" Seed Power, even if the Netherworld God had really tampered with this skull, Su Yu need not be afraid.
He took out the Netherworld Skull, and with a thought, his Giant Will immediately descended, striking the skull.
Previously, he had used the Giant Will to stimulate the Divine Power within the Netherworld Skull, which unleashed a very powerful force when thrown. However, this time, he wasn't aiming to stimulate the skull's power but to transform its energy into Lightning Power.
