"Damn it, the lightning tribulation is here."
Seeing the dark clouds overhead, Xiao Yu shouted and ran toward the edge of the island. The lightning tribulation was immensely powerful; he did not dare remain where he was. Besides, he had already done all he could to help Medusa. Whether she succeeded or not, he still had to consider seizing the Green Lotus Core Flame next. If he fainted from excessive blood loss, not only would he miss out on the Green Lotus Core Flame, he might even be chopped into pieces by the enraged Snake-People Tribe.
The thunderbolts filling the sky caused even those fighting outside Holy City to stop. They all gathered outside the temple, which was now enveloped by a pale purple barrier that kept everyone outside.
In a secluded corner of the temple, Xiao Yan looked at the lightning overhead, swallowed, and asked in a trembling voice, "Teacher, what is that?"
Medicine Elder raised his head to glance at the thunder filling the sky and said with slight astonishment, "I once read an ancient book that recorded how certain powerful magical beasts would undergo the baptism of heavenly tribulation when they were born or advanced. Once they overcame it, their strength would improve tremendously. I never expected to have the chance to witness it with my own eyes."
Amid the lightning and the azure glow of the Heavenly Flame, everyone saw an enormous purple figure standing in the air. Bolt after bolt of lightning struck the giant purple snake before their eyes, splitting its flesh and skin. The beautiful purple scales that had covered its body scattered all around, only to be reduced to ashes beneath the lightning's assault.
As Medusa's hisses gradually weakened, her charred body fell into the center of the island and lay motionless.
