After transmigrating to another world, Green obtained the King of Glory Mall System. He had planned to roam the world with a sword, but then got too busy with work to go.
Starting from scratch in a blacksmith's shop, he went from an unknown blacksmith to researching the power of miracles, guiding the development of mechanical arts, and becoming one of the Empire's Four Great Masters of Mechanical Arts. He repaired the King's Canyon and wielded the Heavenly Book. When the first Tower of the Sun was completed, a cleric who claimed to be immortal emerged from it... The entire continent was left in shock!
