I Have Been Stuck on the Same Day for 3,000 Years

In the year 2065, the newcomer, Lu Feng, entered the Obsidian Ruins in the Shadow World. He was subsequently trapped in an endless time loop of the day of his entry. Three thousand years went by, yet Lu Feng would always reset and start anew at 6 am each day, no matter how many times he died. In order to pass the long millennia, he mastered all the professions found in the Shadow World. To his surprise, what followed a common BOSS battle was not a reset, but the dawn of a new day!
