Yang Xiaotian had two Supreme King Martial Souls.
This time, Yang Xiaotian planned to use his Black Dragon Martial Spirit to absorb the Abyssal Master's Beast Soul.
Although the Black Tortoise and the Black Dragon were both Supreme King Martial Souls, Yang Xiaotian still preferred the Black Dragon Martial Spirit, perhaps because he came from Earth and held a special sentiment for dragons.
Therefore, he intended to use the Black Dragon Martial Spirit to absorb the Abyssal Master.
After all, the Abyssal Master was a Soul Beast nearing two million years of age, a once-in-a-lifetime encounter. To find another nearly two-million-year-old Soul Beast next time would likely be impossible.
The Black Dragon Martial Spirit hovered above Yang Xiaotian's head.
Under Yang Xiaotian's command, the Black Dragon Martial Spirit, reminiscent of the Ancient Divine Mountain, opened its maw and started swallowing the Abyssal Master's Beast Soul.
