Ling Xiao was accidentally reborn into the zombie world and became Ninth Uncle’s younger brother.

Awakening the sky fire system can awaken endless strange fire.

At the same time, you can gain experience points, spells, magical powers, constitution and other rewards by burning all things in the world.

“Senior brother Shi Jian came to kill him? Just in time, let him see how powerful the Nine Dragons Thunder Gang Fire I just awakened is!”

“The ghost king of Fengdu Ghost City is coming to arrest me? Just to show you the taste of hell fire!”

“Ding…Congratulations to the host for burning the sun, gaining experience points: 10 billion! Obtaining bloodline: Golden Crow Divine Body, turning into a new sun!”
