Barbatos was drinking a powerful wine in a goblet made from a massive tooth. It was not a rough affair, but a true artifact. It had been Forged by one of his ancestors from their own tooth.
He needed it to make a wine strong enough to even phase him normally. His Silver Tiger bloodline was highly beneficial with a significant downside as his race advanced. They lost the ability to enjoy a good drink!
His ancestors had worked with anyone, even the wicked sects, to see if there was any way to restore the power of a good drink!
He was not certain of the legend but it was rumored that his ancestor found a Divine Drunken Master. It was apparently considered a serious issue for the Divine Realm cultivator and he made it his mission to let Barbatos' ancestors enjoy drinking once more.
