I Returned with My Golden Core, but My Wife Was Already Ashes

To save my gravely ill wife, I willingly went with my master, a cultivator of the Ruthless Dao, to pursue immortality. He confined me on Spirit Mountain and told me I could either sever my ties of love or reach the Golden Core stage. Otherwise, I was not allowed to leave seclusion. Before I left, I told my wife to wait for me for seven years. I promised I would return after seven years. But on the day I completed my Golden Core, I found only her ashes at the burial ground. The corpse demons nearby said that when she was thrown there, all ten of her fingers had been broken, and her mouth had been tightly sewn shut with thick thread. She had suffered horribly. And the day before I emerged from seclusion, someone had poured oil on her, set her on fire, and ground her bones to dust! All of this was tied to the powerful and wealthy.
