Lin Mo, an outer disciple, was framed by his elder brother for stealing the sect's secret treasure. His spiritual veins were completely shattered and he was left to feed the ants in the mass grave of Ten Thousand Devours. When he was about to die, he swallowed a wisp of the remaining soul of the Demon King that had been sealed for thousands of years in the gap between the monuments - the price was that every time he used the magic power, he would lose a piece of his life memory.
