Su Xiao frowned in thought. He was sure that this blue crystal was definitely something good, but he didn't know what to exchange for it.
Jörmungandr's tentacle slapped the ground, seemingly growing impatient.
Blue Steel Shadow energy gathered in Su Xiao's hand, which was almost representative of the Shadow of Annihilation Law. Sensing the Blue Steel Shadow energy, Jörmungandr's tentacle coiled around it.
With a sizzling sound, the Blue Steel Shadow energy passed over Jörmungandr's tentacle. The tentacle trembled a few times and then nothing more happened.
It wasn't Blue Steel Shadow energy, but as soon as Su Xiao released Blue Steel Shadow energy, Jörmungandr's tentacle immediately coiled around it.
After hesitating for a moment, Su Xiao formed an 800-point strength energy shield in front of him, which was formed by Blue Steel Shadow energy.
