MOUNTAIN SITTING IMMORTAL (MSI)A conduit of the great Dao happened to enter the grotto heaven called Earth. No one had been able to take ownership of this conduit for many years until Marvin came into contact with it. Marvin met the requirement to use the conduit. This allowed him to begin his journey towards immortality. The journey begins from transcending the first mortal coil at Body Forging to transcending the second at Energy Gathering, passing through the subsequent mortal coils, and hopefully to becoming a true immortal with eternal life.But the conduit is far more useful than helping a dying business tycoon gain another lease at life. It is also a conduit of great power. This power and many more will be his as long as he continues to sit on his mountain and grows the mountain into a colossus. The mountain will bring him to greater heights and greater power. This is the story of the Mountain Sitting Immortal.
