Those green flames shouldn't be underestimated. It was probably a condensation of toxic fire, which explains why it felt more domineering than the usual orange flames.
"Open!"
Without hesitation, Lin Jin opened the Visitation Hall's door.
For a while, Lin Jin could borrow its energy to enhance his spells.
Fire's weakness was water.
Water was the most suited to put out these toxic green flames. Even so, the dragon's fire was much too powerful to be doused immediately. Lin Jin was fortunate enough to have the water reservoir scale and Xiao Huo's Dharma body.
Ice possessed Yin energy, so by using the Dharma body to activate the water reservoir scale, Lin Jin could amplify the water's energy by opening the door of the Visitation Hall.
In an instant, a round barrier of water with a hundred-meter radius was erected around Lin Jin. Not only did he protect himself, but he also protected everyone else within the vicinity.
