After Liu Wei opened the Abyss Fang Chain, he was surprised that he seemed to have learned a technique.
He then tried to recall the effects of opening the Abyss Fang Chain in the Blood Demonheart Sutra.
He then mumbled.
"So, it's called Blood Roar Techniques? A qi sound technique, which originates from demonic qi vibrating the throat and lungs, then projecting them outward.
Opening the Abyss Fang Chain will enable me to learn the Stage 1 of the Blood Roar Techniques. The Basic Blood Roar."
From what Liu Wei recalled from the descriptions of the book, which more often than not, he preferred to learn it by discovery, he had to channel his blood qi into his lungs, compressed it, and released it as a guttural roar.
As much as Liu Wei wanted to test it immediately, he wanted to focus on his cultivation.
Hence, he rested his body for three hours, testing the effects of opening the Abyss Fang Chain from time to time.
