The labyrinth that swallowed humanity. Four choices were given to them.

Easy Mode, where anyone can survive. Normal Mode, where only those who fight survive. Hard Mode, where only 1% can survive. And the Solo Mode, where only one person survived.

The strongest returnee of humanity, Kang Taesan, was an Easy Mode player.

He heard countless times,

“What if you had chosen the Hard Mode, or even the Normal Mode?”

Regretting his cowardly choice while dying amidst destruction, he gets another chance to choose.

“This time, I won’t make the wrong choice.”

The strongest Easy Mode player has returned.

When I woke up after a pretty crappy death, what greeted me was one of those famous fantasy worlds! I didn’t expect anything like becoming the strongest with a common job, or rising to the top with the weakest class…All I wanted was to live a slow farming life, but the world just wouldn’t leave me alone!
