I Jumped Off a Cliff but Didn't Die, I Became the Descendant of the Ancestor of Jiuyou

During the family competition, three of my ribs were broken in front of everyone, and I lost my bloodline. The fiancée stood on the high platform and tore up the marriage contract with her own hands, scattering the shredded paper in my face. "From now on, you and I have nothing to do with each other." When she said this, her eyes were colder than the snow in the twelfth lunar month. That night, I stood on the edge of the cliff, ready to end it all. But I was dragged into the abyss by a jade secret that was secretly given to me. At the bottom of the abyss, there is a crazy old man locked up. "Boy, your way of jumping off the cliff is very pleasing to me," he smiled like a liar, "How about being my apprentice?" Later I found out that the shabby book of exercises he taught me was called "Nine Nether Sacred Scriptures". Later I found out that there was a huge conspiracy hidden under the torn-up marriage certificate. Later I found out—— The fiancée who humiliated me in public is the only person in the world who doesn't want me to die.
