Worlds' Strongest

When Ren figures out the key to a puzzle that has stumped Earth’s best and brightest for eons, he will suddenly find himself on a world where the refinement of your soul and the dedication to your craft can unlock ultimate power.

Too bad everyone here seems to want to kill him before he gets the chance.

But if Ren can discover the secret of his own spiritual strength, he might not only find his way in this strange new universe... he will become the strongest person on this world and every other too.
