My Son, the Sword Immortal, Is Reincarnated, Please Don't Lie Down Again

Lu Yuan always felt that his greatest achievement in his life was to raise his somewhat silly son. Until one day, his son gave him a black mud ball and told him that it was the Nine Transformations Golden Pill. Lu Yuan: "Go away, you prodigal thing has been deceived again!" The next second, he was rejuvenated and his body became a saint. The son handed over another broken book and said it was the Ancient Emperor's Scripture. Lu Yuan: "It's too hard to use as toilet paper!" As soon as he finished speaking, the old hen at home realized the truth on the spot after hearing the two words, and spoke with real fire. Lu Yuan was completely confused. It wasn't me who was crazy, it was my world! When his son told him his past life identity and thrust a fire stick into his hand, Lu Yuan finally accepted his fate. Okay, I just want to be an invincible strong man, but can you let me pull the grass out of the ground first?
