At this time, the continent is still a barren wasteland of elements; powerful wizards abandoned this world a thousand years ago to explore the multiverse, becoming little more than elusive legends.Only Su Nan knows that, a thousand years later, the elements will revive, the wizards will return, and the continent is about to enter a prosperous era of magic.So, his task is quite simple: work hard to cultivate and become a wizard, surviving until the age of wizards arrives!“Resource-poor?”“There’s nothing for it; I’ll just have to synthesize everything myself.”Su Nan opens the synthesis cube. This is the story of a traveler with a player panel and a synthesis cube, leveraging a slight advantage of foresight to make a name for himself in a foreign world.

It begins on the mountain.

With the glint of a knife, a flash of steel in the hands of a sworn brother. A betrayal.

Stabbed and pushed down the mountain, Zi Chen lied within the red-stained snow, left to die.

This is where it begins; he is given life by lightning,
baptized by thunder.
