Missing for Three Years, I Return as the King of the Old Ones

Modern City + Invincible Protagonist + Spiritual Qi Revival Three years ago, Gu Chenzhou mysteriously disappeared in a car accident. Everyone thought he was dead. Three years later, he returned to Linhai in ragged clothes, only to find his home gone, his parents missing, and his younger brother caught up in a mysterious research project. Even his identity had long since been completely erased from this world. No one knew that during those three years, he had gone to another world. There, he had climbed to the throne atop mountains of corpses and seas of blood, and subdued countless races at the depths of the abyss. But when he returned, he was gravely wounded and on the verge of death, stripped of all his power and left with a broken body that could collapse at any moment. At first, all he wanted was to find his family and live quietly. But when the dark dealings of the powerful came to light, when an ancient corruption beneath the city began to stir, and when one hidden, uncanny force after another emerged from beneath the veneer of modern order, Gu Chenzhou realized that this seemingly ordinary city had never been clean. With the mortal world in turmoil, the old king returns. In this life, he will turn the city upside down first, then peel back the deepest secrets of this world, one layer at a time.
