The Tao Ancestor Is Above, the Demon Lord Is Below, I Am in Trouble

The time traveler Li Wujiu can be said to have the word "unlucky" carved on his forehead. No system, no grandfather, no family background - a standard three-no product. Relying on his bargaining skills in his previous life, he went to bargain, but was scolded by the market lady to the point where his heart was unbalanced. Then he was sold into a black mine by his "best friend", who promised to "include food and accommodation". Seeing that he was about to turn into a green-eyed mining ghost due to hunger, he made a desperate move with his pickaxe, and unexpectedly dug out a dazzling and blinding strange crystal. As soon as he took it into his arms, he was sucked in and fucked instantly, and he passed out immediately! When I woke up again, I was already overwhelmed by the mountain of corpses, and thunderclouds rolled in the sky, just like the end of the world. Thunder and lightning struck at him like a silver snake that split the sky, and it was only thanks to the "human flesh lightning rod" that he managed to survive. He pinched the culprit's crystal, looked up to the sky and cursed: "Oh my God! Are you the one who invites thunder?!" Before he could finish his words, an unprecedented thunder and lightning struck down with precision as thick as a bowl... With a thunderbolt, he, the unlucky guy, was bound to the Violent Demon Lord and was thrown into the world of cultivation to die. Apart from a confused look, all that's left is the soul asking: Is it too late to be reincarnated now?
