631 Simmer! Superlative!

On the verge of mental derangement, Li Yao was quite befuddled. But he sensed the incoming danger out of instinct and crossed his arms to block the scorpion tail.

However, the enormous, apocalyptic strength inside the scorpion tail pierced into his abdomen, like a bolt of lightning, aimed right at the lump of spiritual energy that he had just condensed!

BOOM!

For a moment, Li Yao felt that a volcano was erupting inside his abdomen. The overwhelming spiritual energy spurted out like magma. All the disordered strength finally found a leak and escaped out of his body in a hurry!

Li Yao was finally back to himself. He was no longer in danger of mental derangement, but he had also come to the painful understanding that his core formation had failed!
