Chapter 41: Strength Upgrade, The Immortal Lightning Dragon

The Underworld Flames emitted by the dragon were considered a special type of magical fire. While not aggressive, it was considered quite 'vicious'. 

It had the characteristics of corrosion, demon-breaking, soul-burning, and curse while fully ignoring a person's defense.

Once attacked, even a god of the same level would become a soulless corpse without any visible wounds on the surface.

The prisoners' leader had used this method to kill several priests within Vogah's divine domain, which was why he had been imprisoned here.

He had thought that the Underworld Flames Dragon could easily kill Sullo.

Then, he could seize the key to open the barrier and escape from this prison planet he was trapped in.

But unexpectedly, the Underworld Flames Dragon was blocked by an ordinary golden light shield.
