Portals appearing all over the world connect to another fantastical realm of swords and magic.
After arriving in another world, Ye Qian, a member of a JSOC special operations team, trained elves in guerrilla warfare, led slaves in overthrowing a noble lord, and rode on a dragon's back as he dived into battle. But during a special reconnaissance mission in the other world, he was captured by Alisa Urandale Lecleran, a young paladin of the temple. After a series of twists and turns, he became the young paladin's adjutant and set out on a journey to find the relics of the saints.
